Abstract
Description
Technical Field
[0001] This utility model belongs to the field of DC motor technology, and specifically relates to a high-protection DC motor. Background Technology
[0002] Traditional DC motors often face the following problems in industrial applications: the motor is prone to displacement or loosening under high load or vibration environments, resulting in unstable operation and affecting equipment accuracy; the mounting base lacks effective protective design, and the motor is susceptible to external impact or dust corrosion, shortening its service life. Utility Model Content
[0003] The main purpose of this utility model is to provide a high-protection DC motor. Through modular stabilizing plate, stress dispersion design and extended connection structure, it achieves high stability, strong protection and flexible installation and adaptation, significantly improving the reliability and maintenance convenience of the motor under complex working conditions.
[0004] To achieve the above objectives, this utility model provides a high-protection DC motor, which includes a DC motor body and a stabilizing plate mounted on the DC motor body. The stabilizing plate has a rectangular outline and a sleeve hole is provided in the center of the stabilizing plate. The motor body passes through the sleeve hole and is fixed inside the stabilizing plate. The stabilizing plate is used to fix the DC motor body.
[0005] The high-protection DC motor provided by this utility model features a stable plate sleeve hole design that ensures a rigid connection between the motor body and the base, suppressing vibration and displacement. The rectangular outline increases the support contact area, disperses the motor's operating load, and improves overall stability.
[0006] In one possible implementation, the four corners of the stabilizing plate are rounded. Rounding eliminates sharp corners, preventing scratches to equipment or personnel during installation and improving safety.
[0007] In one possible implementation, the stabilizing plate has a positioning and fixing hole at each of its four corners. These holes are compatible with standard screw structures, simplifying the installation process and reducing labor costs.
[0008] In one possible implementation, an arc-shaped groove is provided on the inner side of the positioning and fixing hole. The arc-shaped groove disperses the local stress during bolt tightening and prevents cracking around the hole.
[0009] In one possible implementation, a metal connecting plate is disposed on the rear side of the stabilizing plate, and the metal connecting plate is located at the top of the stabilizing plate, extending beyond the top of the stabilizing plate. The metal connecting plate provides expansion interfaces for peripherals (such as heat sinks and sensors), enhancing functional integration. Attached Figure Description
[0010] Figure 1 This is a schematic diagram of a high-protection DC motor structure provided by this utility model. Detailed Implementation
[0011] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.
[0012] In the description of this application, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0013] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.
[0014] See attached diagram. Figure 1 , Figure 1 This is a schematic diagram of a high-protection DC motor structure provided by this utility model, as shown below. Figure 1 As shown, the present invention provides a high-protection DC motor including a DC motor body 1, a stabilizing plate 2 installed on the DC motor body 1, the stabilizing plate 2 having a rectangular outline, a sleeve hole provided in the center of the stabilizing plate 2, the motor body passing through the sleeve hole and fixed inside the stabilizing plate 2, the stabilizing plate 2 being used to fix the DC motor body 1.
[0015] The high-protection DC motor provided by this utility model features a stabilizing plate with two sets of holes to ensure a rigid connection between the motor body and the base, suppressing vibration and displacement. The rectangular outline increases the support contact area, disperses the motor's operating load, and improves overall stability.
[0016] In one possible implementation, the four corners of the stabilizing plate 2 are rounded. Rounding eliminates sharp corners, preventing scratches to equipment or personnel during installation and improving safety.
[0017] In one possible implementation, the stabilizing plate 2 has a positioning and fixing hole 3 at each of its four corners. The positioning and fixing holes 3 are compatible with standard screw structures, simplifying the installation process and reducing labor costs.
[0018] In one possible implementation, an arc-shaped groove 4 is provided on the inner side of the positioning and fixing hole 3. The arc-shaped groove 4 disperses the local stress during bolt tightening and prevents cracking around the hole.
[0019] In one possible implementation, a metal connecting plate 5 is disposed on the rear side of the stabilizing plate 2, and the metal connecting plate 5 is disposed at the top of the stabilizing plate 2, extending beyond the top of the stabilizing plate 2. The metal connecting plate 5 provides an expansion interface for peripherals (such as heat sinks and sensors), enhancing functional integration.
[0020] It is worth mentioning that those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
