Description

Technical Field

[0001] This utility model relates to the field of electromagnetic brake housing technology, specifically to a motor with an electromagnetic brake module. Background Technology

[0002] Chinese patent application No. 201822219388.0 discloses a motor housing with heat dissipation effect, including a housing body. The housing body includes a motor mounting part and a driver mounting part connected to the outer peripheral wall of the motor mounting part. The lower end face of the motor mounting part and the lower end face of the driver mounting part are on the same plane, and there is a height difference between the upper end face of the motor mounting part and the upper end face of the driver mounting part. An opening groove with a U-shape is opened on the outer peripheral surface of the motor mounting part, which leads to the driver mounting part.

[0003] In the above technical solution, a conventional motor housing is installed on the motor to isolate and seal the internal structure of the motor. However, when using the motor housing in the above technical solution to isolate and seal the electromagnetic brake in the motor, the edges of the motor housing need to be fastened with screws or bolts, which makes the disassembly and assembly of the motor housing cumbersome. Each screw or bolt needs to be unscrewed to adjust the motor housing. Moreover, once the screws or bolts rust, they become difficult to unscrew, making it inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to provide a motor with an electromagnetic brake module that can quickly lock the motor housing to isolate and seal it from the electromagnetic brake.

[0005] To achieve the above objectives, this utility model discloses a motor with an electromagnetic brake module, including a motor body. An electromagnetic brake module is provided at one axial end of the motor body, and a cover body for protecting the electromagnetic brake module is provided at this end. The cover body has a cylindrical structure, and an extension is provided on the axial end face of the cover body away from the electromagnetic brake module. The extension facilitates the user to apply force to the cover body to move or rotate the cover body. A radial opening is provided at one end of the cover body relative to the extension. Assembly parts are symmetrically provided at both ends of the opening near the radial opening on the outer circumferential surface of the cover body. A bolt is provided between the two assembly parts, and the bolt can bring the two assembly parts closer together to tighten the cover body.

[0006] When it is necessary to isolate and seal the electromagnetic brake module in the motor, place the cover body at the end corresponding to the electromagnetic brake module in the motor, and make the cover body fit with the motor body. Use bolts to bring the assembly parts located at both ends of the radial opening closer to each other. During the process of the cover body being locked by the bolts, the inner wall of the cover body abuts against the motor body, thereby making the cover body and the motor body concentric and completing the installation, thus achieving the isolation and sealing of the electromagnetic brake module.

[0007] This utility model, through the radial opening and assembly part design on the cover body, requires only a small number of bolts to fix the cover, ensuring concentric installation of the cover body and the motor body, avoiding the use of a large number of screws or bolts for edge fastening. When the electromagnetic brake module needs to be maintained or replaced, the staff can disassemble the cover body more quickly, reducing the inconvenience caused by rusted or difficult-to-unscrew screws, thus greatly simplifying the disassembly and assembly process and improving work efficiency. This utility model has the advantage of being able to quickly lock the motor housing to isolate and seal it from the electromagnetic brake.

[0008] Preferably, the cover body includes an inner cover fitted onto the electromagnetic brake module and an outer cover fitted onto the outside of the inner cover.

[0009] By setting two interlocking inner and outer covers, it is easier to adjust only the outer cover during installation without having to adjust the inner cover as well. This allows for separate adjustments to the inner and outer structures of the cover body, increasing the degree of freedom during product installation.

[0010] Preferably, the extension is provided on the outer cover, the radial opening is provided through the outer cover symmetrical to one end of the extension, the two mounting parts are respectively located at the two ends of the radial opening on the outer cover along the circumferential direction, and the ends of the two mounting parts that are close to each other are parallel planes.

[0011] Since the cover body is divided into an inner cover and an outer cover, when adjusting the extension on the outer cover, only the relative angle between the outer cover and the inner cover needs to be adjusted. In the actual installation process of the electromagnetic brake, while ensuring the installation position of the electromagnetic brake for different vehicle motors, the relative angle of the outer cover is adjusted so that the extension on the outer cover is in a position that is convenient for the user to apply force.

[0012] Preferably, the outer circumferential surface of the inner cover has a plurality of grooves arranged in an annular array along the axial direction of the motor body. Each groove includes a lateral slot with its opening facing away from the axis of the inner cover and an axial slot located away from the electromagnetic brake module. The inner circumferential surface of the outer cover is provided with a protrusion that cooperates with the groove.

[0013] By setting grooves on the outer circumferential surface of the inner cover and setting protrusions on the inner circumferential surface of the outer cover, the outer cover is circumferentially limited to prevent the angle between the outer cover and the inner cover from changing. The entire circumferential area is divided into sections according to the number of protrusions, thereby adjusting the angle between the outer cover and the inner cover in a fixed way.

[0014] Preferably, the groove and the convex strip have a narrowing structure from the end away from the electromagnetic brake module to the end closer to the electromagnetic brake module.

[0015] By setting the grooves and ridges into a constricted shape, it is easier for the outer cover and inner cover to be demolded during the actual production process.

[0016] Preferably, the inner cover has a plurality of positioning grooves symmetrically arranged on its outer circumferential surface, and the outer cover has positioning blocks that fit into the positioning grooves on its inner circumferential surface.

[0017] During the process of moving the outer cover closer to the inner cover, the user is informed of the actual position of the outer cover by inserting the positioning block into the positioning groove, which facilitates the user's installation of the outer cover.

[0018] Preferably, the inner cover has a mounting groove at the axial position near the electromagnetic brake module end that matches the brake clutch flange, and the axial position of the inner cover has a screw set for use with the brake clutch flange of the electromagnetic brake module, which facilitates the installation between the inner cover and the electromagnetic brake module, and ensures the stability of the inner cover relative to the electromagnetic brake module after installation through the mounting groove and the screw set.

[0019] Preferably, the outer cover has a through hole at its axial position, and the opening range of the through hole is larger than the coverage range of the screw assembly.

[0020] By providing through holes in the outer cover, users can easily access the screw assembly of the inner cover through the outer cover, simplifying the disassembly and assembly process of the cover body.

[0021] Preferably, at least one end of the two assembly parts along the axial direction of the motor and the other end that is far apart from each other along the circumferential direction are provided with inclined surfaces. The inclined surfaces make the end of the assembly part away from the outer cover narrow in shape, which facilitates the flow of plastic material in the mold during the actual production process of the outer cover and ensures the production quality of the outer cover.

[0022] This invention requires only a small number of bolts to fix the cover, ensuring concentric installation of the cover body and the motor body, avoiding the use of a large number of screws or bolts for edge fastening, and has the advantage of being able to quickly lock the motor housing to isolate and seal it from the electromagnetic brake.

[0029] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0030] Depend on Figure 1 As shown, this embodiment discloses a motor with an electromagnetic braking module, including a motor body 11. An electromagnetic braking module 13 is provided at one axial end within the motor body 11. A cover body 12 for protecting the electromagnetic braking module is provided at this end. The cover body 12 has a cylindrical structure with the same diameter as the motor body 11. A sealing structure, a corrugated sealing ring 21, is provided between the cover body 12 and the motor body 11. The cover body 12 includes an inner cover 14 fitted onto the electromagnetic braking module 13 and an outer cover 15 fitted onto the outside of the inner cover 14. Figure 5 As shown, the inner cover 14 has a hexagonal mounting groove 141 at the axial position near one end of the electromagnetic brake module 13, which matches the brake clutch flange 131. Figure 2 As shown, the inner cover 14 is provided with a screw assembly 18 at the axial position for use with the brake clutch flange 131 of the electromagnetic brake module 13. The screw assembly 18 is assembled at the hexagonal position of the mounting groove 141, which facilitates the installation between the inner cover 14 and the electromagnetic brake module 13. The mounting groove 141 and the screw assembly 18 ensure the stability of the inner cover 14 relative to the electromagnetic brake module 13 after installation.

[0031] An extension 16 is provided on the axial end face of the outer cover 15 away from the electromagnetic brake module 13. The extension 16 is located on the outer cover 15 at the end away from the axis. The extension 16 facilitates the user to apply force to the cover body 12. A through hole 151 is provided at the axis position of the outer cover 15. The opening range of the through hole 151 is larger than the coverage range of the screw assembly 18. A radial opening 17 is provided on the outer cover 15 at the end radially opposite to the extension 16. The radial opening 17 penetrates the outer cover 15 along the axial direction. An assembly part 19 is provided on the outer circular surface of the outer cover 15 for use with the fastening bolt 20.

[0032] Two assembly parts 19 are located at the two ends of the radial opening 17 on the outer cover 15 along the circumferential direction. The ends of the two assembly parts 19 that are close to each other are parallel planes. Figure 3 As shown, both assembly parts 19 are provided with inclined surfaces 191 at one end along the axial direction of the motor and at the other end that is far apart from each other along the circumferential direction. The inclined surfaces 191 make the end of the assembly part 19 away from the outer cover 15 narrow. The bottom surfaces of the two assembly parts 19 and the bottom surface of the outer cover 15 are located on the same plane.

[0033] Since the cover body 12 is divided into an inner cover 14 and an outer cover 15, when adjusting the extension 16 located on the outer cover 15, it is only necessary to adjust the relative angle between the outer cover 15 and the inner cover 14. In the actual installation process of the electromagnetic brake, while ensuring the installation position of the electromagnetic brake for different vehicle motors, the relative angle of the outer cover 15 is adjusted so that the extension 16 on the outer cover 15 is in a position that is convenient for the user to apply force.

[0034] Depend on Figure 4 , Figure 5 As shown, the outer circumferential surface of the inner cover 14 has eight sets of grooves 142 arranged in a ring along the axial direction of the motor body 11. Each groove 142 includes a lateral slot with an opening facing away from the axis of the inner cover 14 and an axial slot located away from the electromagnetic brake module 13. The inner circumferential surface of the outer cover 15 is provided with a protrusion 152 that cooperates with the grooves 142, thereby dividing the entire circumferential area of ​​the inner cover 14 into sections, thereby adjusting the angle of the outer cover 15 relative to the inner cover 14 at a fixed value of 45°.

[0035] The groove 142 and the ridge 152 have a narrowing structure from the end away from the electromagnetic brake module 13 to the end close to the electromagnetic brake module 13, which facilitates the demolding of the outer cover 15 and the inner cover 14 during the actual production process.

[0036] The inner cover 14 has several symmetrically arranged positioning grooves 143 on its outer circumferential surface, and the outer cover 15 has positioning blocks 153 that fit into the positioning grooves 143 on its inner circumferential surface.

[0037] When it is necessary to isolate and seal the electromagnetic brake module 13 in the motor, place the inner cover 14 at the end corresponding to the electromagnetic brake module 13 in the motor, and align the mounting groove 141 of the inner cover 14 with the brake clutch flange 131. Secure the inner cover 14 to the brake clutch flange 131 using the screw assembly 18. After the inner cover 14 is installed, adjust the position of the extension 16 according to actual installation needs to determine the angle of the outer cover 15 relative to the inner cover 14, so that the protrusion 15 of the outer cover 15... 2. The outer cover 15 is moved towards the inner cover 14, opposite to the groove 142 of the inner cover 14, until the positioning block 153 of the outer cover 15 is embedded in the positioning groove 143 of the inner cover 14. At this time, the fastening bolt 20 is rotated, and the fastening bolt 20 brings the two assembly parts 19 closer to each other and closes the radial opening 17, so that the outer cover 15 and the inner cover 14 fit together, thereby completing the installation between the outer cover 15, the inner cover 14 and the motor body 11, and realizing the isolation and sealing of the electromagnetic brake module 13.
