Abstract
Description
Technical Field
[0001] The present application relates to the field of motor casings, and in particular to a high-strength casing. Background Art
[0002] The outer wall of the motor housing is usually spaced apart and symmetrically extended to the outside by two plates as mounting legs. When the motor is fixed to the work platform, the mounting legs are fixed to the platform by bolts, thereby fixing the entire motor to the platform.
[0003] Because the entire weight of the motor is applied to the mounting foot, the mounting foot is typically integrally formed with the motor housing in related art. However, since the mounting foot is a cantilevered plate, the contact surface between the mounting foot and the motor housing is only on one side, resulting in a small contact area and weak connection strength. When the mounting foot is subjected to a large impact or encounters a bump, the mounting foot is prone to breakage, thereby affecting the use of the entire motor. Utility Model Content

[0008] In order to improve the axial strength of the casing body, a plurality of reinforcement rings are fixedly provided on the outer wall of the casing body, and the plurality of reinforcement rings are arranged at intervals along the extension direction of the casing body.
[0009] In order to improve the radial strength of the casing body, a reinforcement strip is fixedly provided on the outer wall of the casing body. The extension direction of the reinforcement strip is consistent with the length direction of the casing body, and the reinforcement strip intersects with the multiple reinforcement rings.
[0010] In order to improve the heat dissipation effect inside the casing body, a plurality of heat dissipation blades are provided on the outer wall of the casing body, and the plurality of heat dissipation blades are arranged at intervals circumferentially on the casing body.
[0011] In order to increase the functionality of the mounting base while reducing the material cost of the mounting base, a mounting groove for mounting a capacitor is opened on the outer wall of one side of the mounting base, and a dustproof cover is provided at the notch of the mounting groove.
[0012] A cable groove for storing excess cables of the motor is provided on a side of the mounting seat away from the mounting groove, and a shielding cover is provided at the notch of the cable groove.
[0013] In order to allow the cables to pass through the cable groove and connect to the power supply, the shielding cover is provided with a wire hole for the cables to pass through.
[0014] In order to fix the mounting seat without affecting the space in the mounting groove and the cable groove, countersunk holes for bolt installation are provided on the groove walls of the mounting groove and the cable groove on the side close to the ground, and the countersunk holes pass through the mounting seat.

[0019] 3. The installation slots and cable slots ensure the strength of the mounting base and the housing body, reduce the material used for the mounting base and reduce the cost. At the same time, the installation slots and cable slots also improve the functionality of the mounting base.
[0020] 4. The heat sink, dust cover and heat dissipation fins on the shielding cover increase the contact area between the housing body and the outside air, thereby improving the heat dissipation effect of the housing body. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following is combined with Figure 1-3 This application is described in further detail.
[0026] The embodiment of the present application discloses a high-strength housing. Figure 1 The high-strength housing includes a housing body 1 and a mounting base 2. The mounting base 2 has a U-shaped placement slot, into which the housing body 1 is inserted, so that the mounting base 2 partially wraps around the housing body 1. The housing body 1 and the mounting base 2 are integrally formed, and the housing body 1 is secured to the mounting platform via the mounting base 2. The placement slot on the mounting base 2 increases the contact area between the mounting base 2 and the housing body 1, thereby improving the overall strength of the housing.
[0027] Reference Figure 1 The housing body 1 is a cylindrical structure with openings at both ends. It rests horizontally on the mounting base 2, with its axial ends protruding from opposite sides of the mounting base 2, forming a cantilevered state. Reinforcing ribs 11 are integrally formed between the portions of the housing body 1 that protrude from the placement slots at both ends and the mounting base 2. Multiple ribs 11 are provided, spaced apart vertically, thereby increasing the strength between the protruding portion of the housing body 1 and the mounting base 2.
[0028] Reference Figure 1 and Figure 2 A reinforcement ring 12 is integrally formed on the outer wall of the housing body 1, with the center of the reinforcement ring 12 coinciding with the center of the housing body 1. Multiple reinforcement rings 12 are provided, spaced apart along the axial direction of the housing body 1. When the housing body 1 is subjected to an axial impact force, the reinforcement rings 12 prevent the housing body 1 from significantly bending, thereby providing better protection for the components within the housing body 1.
[0029] Multiple reinforcement strips 13 are integrally formed on the outer wall of the housing body 1. These strips 13 extend in the same direction as the axial direction of the housing body 1, and each strip 13 intersects with multiple reinforcement rings 12. The strips 13 are spaced apart along the circumference of the housing body 1. When the housing body 1 is subjected to an external radial impact, the reinforcement strips 13 enhance the strength of the housing body 1, preventing it from denting.
[0030] Reference Figure 1 and Figure 2 Furthermore, heat dissipation fins 14 are integrally formed on the outer wall of the housing body 1 , extending in the same direction as the axial direction of the housing body 1 . Multiple heat dissipation fins 14 are provided, spaced apart along the circumference of the housing body 1 . This increases the contact area between the housing body 1 and the air, improving the heat dissipation of the housing body 1 . Due to the presence of the reinforcement strips 13 , multiple heat dissipation fins 14 are arranged between each two adjacent reinforcement strips 13 , ensuring that the heat dissipation fins 14 do not interfere with the effectiveness of the reinforcement strips 13 .
[0031] Reference Figure 2 and Figure 3 Mounting base 2 has a mounting slot 21 defined on its outer wall, perpendicular to the horizontal side of the mounting groove 21. This slot 21 accommodates the motor's capacitors, which balance the motor's voltage and current, maintaining stable operation. A countersunk hole 22 is defined on the wall of the mounting groove 21, located near the ground, and extends through the mounting base 2. Bolts can be inserted into these holes to secure the mounting base 2 to the mounting platform. Furthermore, bolts passing through the countersunk holes 22 are less likely to protrude into the mounting slot 21 and interfere with the capacitors.
[0032] Reference Figure 2 and Figure 3 The notch of the mounting slot 21 is covered with a dust cover 23, which is fixed to the mounting base 2 by bolts, thereby preventing dust and the like from entering and accumulating in the mounting slot 21. In addition, a plurality of heat dissipation fins 24 are provided on the outer wall of the dust cover 23 on the side facing away from the mounting slot 21. The plurality of heat dissipation fins 24 are arranged at intervals along the vertical direction, thereby improving the heat dissipation effect of the housing body 1.
[0033] Reference Figure 2 and Figure 3 A cable groove 25 is provided on the side of the mounting base 2 facing away from the mounting slot 21. Excess power cables from the motor can be stored in the groove, keeping the motor neat and tidy during use. Similarly, countersunk holes 22 for bolt insertion are provided on the wall of the cable groove 25 on the side closest to the ground. A shielding cover 26 is bolted to the notch of the cable groove 25, shielding the notch. The outer wall of the shielding cover 26, facing away from the mounting base 2, is also provided with a plurality of heat dissipation fins 24, spaced apart vertically.
[0034] A wire hole 27 is provided on the outer wall of the shielding cover 26, and the wire hole 27 passes through the shielding cover 26 itself and is connected to the cable groove 25. The power line on the motor can pass through the wire hole 27 and be connected to an external power line or power supply.
[0035] The high-strength housing of this embodiment is implemented as follows: the mounting base 2 partially encloses the housing body 1 through the placement groove, increasing the contact area with the housing body 1. Simultaneously, the reinforcing ribs 11 reinforce the overhanging portion of the housing body 1. The provision of the reinforcing ring 12 and reinforcing strips 13 increases the radial and axial strength of the housing body 1, thereby enhancing the overall strength of the motor housing.
[0036] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
