Description

Technical Field

[0001] This utility model belongs to the field of brushless motor technology, specifically relating to a plastic-encapsulated DC brushless motor. Background Technology

[0002] A brushless motor is a typical mechatronic product consisting of a motor body and a driver. Because brushless DC motors operate in a self-controlled manner, they do not require additional starting windings on the rotor like synchronous motors that start under heavy loads with frequency conversion speed regulation. They also do not experience oscillations or loss of synchronism when the load changes abruptly. The operating efficiency, low-speed torque, and speed accuracy of brushless DC motors are better than those of frequency converters with any control technology, making them worthy of industry attention.

[0003] According to CN214543879U, a plastic-encapsulated waterproof DC brushless motor is disclosed. This technology discloses "a protective cover, an airbag, a fixing rod, a cone head, a locking block, an ear plate, a fixing sleeve, a mounting hole, a brushless motor body, a fixing ring, a sealed bearing, a telescopic air bag, an air tube, a limit ring, a spring, a first fixing block, a connecting rod, a fixing head, a guide rod, a second fixing block, a fixing shaft, a fixing groove, and a connecting shaft. The brushless motor body is uniformly fitted with three fixing rings on its outer circumference. This utility model improves the waterproof performance of the brushless motor body by setting an outer protective cover and a sealed bearing, which is beneficial to improving the ability of the brushless motor body to work in humid and underwater conditions and expanding the application range of the brushless motor body. By pressing and releasing the airbag, the locking block can rotate and reset along the fixing shaft. It is also beneficial to achieve quick installation and disassembly of the device by engaging the locking block with the fixing hole, which is beneficial to improving work efficiency."

[0004] Although the design enables quick installation and disassembly of the device through the engagement of the locking block and the fixing hole, which is beneficial to improving work efficiency, the device can only be installed in a single direction when installing the plastic casing. When it is necessary to install it in a vertical direction, the device lacks the necessary fixing structure, making it difficult to achieve stable installation.

[0005] To address the aforementioned issues, this application proposes a plastic-encapsulated brushless DC motor. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] like Figure 1 As shown:

[0025] A plastic-encapsulated brushless DC motor includes a plastic-encapsulated housing 1.

[0026] In this implementation plan: The existing patent (publication number CN214543879U) discloses a waterproof DC brushless motor with a plastic-encapsulated structure. This patent discloses a protective cover. The plastic-encapsulated shell 1 in this application adopts the same technical means as the prior art. The technical means will not be described in detail here. For details on the improvement of the prior art, please refer to the following disclosure. In order to solve the technical problems existing in the prior art, such as the background art disclosed above, "when the device installs the plastic-encapsulated shell 1, it can only be installed in a single direction. When it needs to be installed in a vertical direction, the device lacks the necessary fixing structure, making it difficult to achieve stable installation." In combination, this problem is obviously a real and difficult problem to solve. Therefore, in order to solve the above problems, a vertical mounting head 2 and a horizontal mounting head 3 are added on the basis.

[0027] Furthermore:

[0028] like Figure 1 - Figure 5 As shown:

[0029] In conjunction with the above, it also includes a vertical mounting head 2, a horizontal mounting head 3, a rotating shaft 4, an adjusting plate 5, a connecting block 6, and a base plate 7, all located on one side of the plastic seal 1. The vertical mounting head 2 and the horizontal mounting head 3 are fixedly mounted on the surface of the plastic seal 1, and the rotating shaft 4, which is slidably connected to the adjusting plate 5, is also fixedly mounted on the surface of the plastic seal 1. One end of the adjusting plate 5 is also fixedly connected to the surface of the connecting block 6, and the connecting block 6 is also fixedly connected to the surface of the base plate 7. The base plate 7 is also in close contact with the surface of the plastic seal 1.

[0030] In this implementation scheme: When it is necessary to install the plastic seal 1, the bottom surface of the plastic seal 1 and the base plate 7 can be kept in a close fit. At this time, the rotating shaft 4 is located at the bottom of the adjusting plate 5, while the connecting block 6 above the adjusting plate 5 and the vertical mounting head 2 are kept in a close fit. The horizontal mounting head 3 is not connected to other components. Then, the bolt can be passed through the vertical mounting head 2, the adjusting plate 5, and the connecting block 6 on one side of the base plate 7 to complete the installation of the plastic seal 1. When the working environment changes and the plastic seal 1 needs to be used horizontally, the adjusting plate 5 and the rotating shaft 4 can be slid together. At this time, the rotating shaft 4 will gradually move from the adjusting plate 5 to the horizontal position. The bottom of plate 5 moves to the top of adjusting plate 5, and the plastic seal 1 and the base plate 7 will gradually separate. Then, the adjusting plate 5 can be rotated around the pivot 4. The adjusting plate 5 will drive the connecting block 6 and the base plate 7 to rotate 90 degrees around the plastic seal 1 around the pivot 4. At this time, the connecting block 6 will point to the direction of the horizontal mounting head 3. Then, the pivot 4 and the adjusting plate 5 can be slid together again, and the base plate 7 will fit against the side of the plastic seal 1. The connecting block 6 will then be connected to the horizontal mounting head 3. Then, the plastic seal 1 can be fixed again with bolts, thus completing the horizontal installation of the plastic seal 1.

[0031] Furthermore:

[0032] In an optional embodiment, the bottom of the plastic casing 1 is cube-shaped.

[0033] In this embodiment, the cube-shaped plastic seal 1 can be connected to the vertical mounting head 2 and the horizontal mounting head 3 on the surface of the plastic seal 1 before and after the adjustment plate 5 rotates, which can provide favorable conditions for different installation postures of the plastic seal 1.

[0034] Furthermore:

[0035] In an optional embodiment, the vertical mounting head 2 and the horizontal mounting head 3 are arranged perpendicular to each other.

[0036] In this embodiment, the vertical mounting head 2 and the horizontal mounting head 3, which are arranged perpendicularly to each other, can be connected to either the vertical mounting head 2 or the horizontal mounting head 3 before or after the adjustment plate 5 rotates, thereby allowing the installation posture of the plastic casing 1 to be flexibly adjusted.

[0037] Furthermore:

[0038] In an optional embodiment, the rotating shaft 4 is symmetrically arranged on both sides of the surface of the plastic casing 1.

[0039] In this embodiment, the rotating shafts 4 symmetrically arranged on both sides of the surface of the plastic casing 1 can provide favorable conditions for the installation of the adjustment plate 5 and ensure the rotation and sliding operation of the adjustment plate 5.

[0040] Furthermore:

[0041] In an optional embodiment, the surface of the adjusting plate 5 is provided with an elliptical groove that matches the rotating shaft 4.

[0042] In this embodiment: the groove opened on the surface of the adjustment plate 5 enables smooth sliding between the adjustment plate 5 and the plastic seal 1, and after sliding between the adjustment plate 5 and the plastic seal 1, the two can rotate.

[0043] Furthermore:

[0044] In an optional embodiment, the connecting blocks 6 are symmetrically arranged at both ends of the adjusting plate 5.

[0045] In this embodiment, the connecting blocks 6 symmetrically arranged at both ends of the adjusting plate 5 can form a stable connection between the adjusting plate 5 and the vertical mounting head 2 or the horizontal mounting head 3, thereby making the installation of the plastic shell 1 more reliable and ensuring the stability of its working environment.

[0046] The working principle and usage process of this utility model are as follows: When it is necessary to install the plastic seal 1, the bottom surface of the plastic seal 1 and the base plate 7 can be kept in a close fit. At this time, the rotating shaft 4 is located at the bottom of the adjusting plate 5, while the connecting block 6 above the adjusting plate 5 and the vertical mounting head 2 are kept in a close fit. The horizontal mounting head 3 is not connected to other parts. Then, the bolt can be passed through the vertical mounting head 2, the adjusting plate 5, and the connecting block 6 on one side of the base plate 7 to complete the installation of the plastic seal 1. When the working scene changes and the plastic seal 1 needs to be used horizontally, the adjusting plate 5 and the rotating shaft 4 can be slid together. At this time, the rotating shaft 4 will... Gradually move from the bottom to the top of the adjusting plate 5, and the plastic seal 1 and the base plate 7 will gradually separate. Then, the adjusting plate 5 can be rotated around the pivot 4, and the adjusting plate 5 will drive the connecting block 6 and the base plate 7 to rotate 90 degrees around the plastic seal 1 around the pivot 4. At this time, the connecting block 6 will point in the direction of the horizontal mounting head 3. Then, the pivot 4 and the adjusting plate 5 can be slid together again, and the base plate 7 will fit against the side of the plastic seal 1. The connecting block 6 will then connect with the horizontal mounting head 3. Then, the plastic seal 1 can be fixed again with bolts, thus completing the horizontal installation of the plastic seal 1.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, 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.
