Description

Technical Field

[0001] This utility model relates to the field of assembly technology for brushless DC motors containing gearboxes, and more particularly to assembly mechanisms for brushless DC motors. Background Technology

[0002] Electric motors, as commonly used drive mechanisms, are widely used in various electrical appliances, especially small household appliances such as smart trash cans, fans, rice cookers, and air fryers. However, in current technology, motors are directly mounted on the bottom or top of these devices, and they are assembled as a single unit. But for complex devices, such as smart trash cans that require multiple steps to dispose of garbage, the base and top need to be detachable. If the motor is directly mounted on the base, too many holes need to be drilled for the assembly of the motor and motor bracket, making the assembly cumbersome and difficult to remove once fixed. Utility Model Content

[0003] The purpose of this utility model is to provide an assembly mechanism for brushless DC motors, which allows the motor and gearbox to be directly assembled by inverting the motor bracket, making disassembly and installation convenient.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0009] An isolation mechanism is mounted on the motor bracket, which isolates the gearbox from the motor bracket and the base respectively.

[0014] Furthermore, the stepped structure extends downward to form several reinforcing ribs that contact the upper isolation plate.

[0015] Furthermore, the isolation mechanism is equipped with an assembly plate near the base, and the assembly plate is provided with several inverted electrical components, which are suspended above the base.

[0016] Furthermore, the motor is positioned close to the base, and the motor and gearbox are respectively positioned at both ends of the motor bracket.

[0029] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.

[0030] See attached document Figure 1-6 As shown, the assembly mechanism for the brushless DC motor in this embodiment includes a base 100. The base 100 can be an assembly base for other small household appliances, generally located at the bottom. To facilitate installation, a motor bracket 200 is inverted on the base 100, that is, the top of the motor bracket 200 contacts and is assembled with the base 100, and the top is suspended. Specifically, a motor 210 is mounted on the motor bracket 200, and the motor 210 is positioned facing the base 100.

[0031] In this embodiment, the motor is a brushless DC motor. A gearbox is needed to reduce its speed. Therefore, a gearbox 220 is included, located on the side of the motor bracket 200 and offset from the motor 210. The gearbox 220 is suspended above the base 100. Since the main source of noise during operation of the brushless DC motor is the gearbox, noise propagation needs to be reduced. Therefore, in this embodiment, an isolation mechanism 300 is installed on the motor bracket 200. The isolation mechanism 300 isolates the gearbox 220 from both the motor bracket 200 and the base 100, effectively isolating the gearbox. The noise generated by the gearbox during operation is isolated by the isolation mechanism 300 and forms an airflow dispersion trajectory within the isolation mechanism 300. This internal airflow dispersion trajectory disperses the noise, achieving noise reduction.

[0032] In this embodiment, not only is the assembly of motors and the like facilitated, but the noise of the gearbox during the use of brushless geared DC motors is also addressed, thereby improving the user experience and reducing noise pollution.

[0033] In this embodiment, to facilitate the assembly of multiple mechanisms, the motor bracket 200 forms an assembly shell, such as an assembly cavity with only an opening facing the base. Since the gearbox 220 is relatively large, and to prevent it from being too close to the base, the assembly shell can be partially protruded to form a stepped structure 230. The stepped structure 230 protrudes, and the gearbox 220 is then assembled below the stepped structure 230. Alternatively, the stepped structure 230 can be provided at other locations on the assembly shell, such as the side of the motor, to allow for clearance.

[0034] Specifically, the isolation mechanism 300 includes an upper isolation plate 310 and a lower isolation plate 320, which are fixed to the lower part of the stepped structure 230 by bolts 400. This makes the entire isolation mechanism essentially suspended, enclosing the entire gearbox, thus not only preventing structural interference from its rotation during use but also providing localized noise isolation.

[0035] To complete the assembly of the isolation mechanism, the stepped structure 230 extends downwards in a portion to form a snap-fit ​​groove 240. The bolt 400 extends into the snap-fit ​​groove 240 and forms a transition gap with the snap-fit ​​groove 240. In this embodiment, the bolt 400 is actually fixed to the upper and lower isolation plates, and then rotates into the snap-fit ​​groove 240 by threading to complete the assembly. The bolt is not fully inserted into the snap-fit ​​groove; its purpose is to form a transition gap. At this time, if torsion occurs due to the rotation of the motor and gearbox during use, the torsional force can be dispersed through the gap.

[0036] In this embodiment, to synchronously isolate the motor, the upper isolation plate 310 can be extended to form a protective surface for the motor 210, and a through hole is provided on the protective surface for the motor output shaft to pass through. At this time, the motor output shaft passes through the upper isolation plate and approaches the motor bracket, so that it matches the structure on the motor bracket.

[0037] In this embodiment, the motor bracket is inverted, and a separate support structure can be formed on top of it, on which various structures can be assembled.

[0038] To improve overall strength, the stepped structure 230 extends downward to form several reinforcing ribs 231 that contact the upper partition plate 310.

[0039] In this embodiment, in order to assist the operation of the motor, etc., a power supply and a main control board are also required. The isolation mechanism 300 is equipped with an assembly plate 500 near the base. The assembly plate 500 is provided with several inverted electrical components. The electrical components are suspended above the base. At this time, the assembly of the relevant accessories is completed.

[0040] To reduce interference during the rotation of the motor and gearbox, the motor 210 is positioned close to the base 100, and the motor 210 and gearbox 220 are respectively located at both ends of the motor bracket 200. In this configuration, the motor and gearbox are positioned one below the other, and horizontally, one is on the left and the other on the right, ensuring misalignment.

[0041] To enable plug-in and detachable assembly, the motor bracket 200 is provided with a slot 250, and the base 100 is provided with an insertion part 110 that matches the slot 250. This plug-in assembly method is simple and facilitates disassembly and assembly.

[0042] Furthermore, in this embodiment, a double plug-in connection is used. Specifically, the insertion part 110 has an H-shaped structure, and a limiting groove 111 is formed on the H-shaped structure to accommodate the slot. At this time, the entire slot 250 is first inserted into the limiting groove 111, and then the insertion rod 112 extends upward from the middle of the limiting groove 111. At this time, the insertion rod matches the slot 250 to complete the second double plug-in connection.

[0043] The brushless DC motor assembly mechanism in this embodiment is used in the intelligent waste processor. The motor bracket 200 is then inverted to form a support part, and subsequent mixing tanks and heating and other multiple processing devices can be assembled onto the motor bracket to achieve multiple benefits.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
