Description

Technical Field

[0001] This utility model relates to the field of micro motor technology, and in particular to a protective end cap for micro motors. Background Technology

[0002] Micromotors, as efficient and precise miniature drive devices, have been widely used in various fields such as smart devices, robots, medical instruments, and automotive electronics. With continuous technological advancements, micromotors are becoming increasingly smaller, while performance requirements are gradually increasing. During their efficient operation, micromotors, due to their compact structure, high operating speed, and large load, are highly susceptible to external environmental factors such as chemical corrosion and mechanical impact, which can interfere with their normal operation or even cause damage. Therefore, protective end caps, as an important component of micromotors, play a crucial role in protecting the motor from harsh environmental conditions.

[0003] In existing technologies, most micro-motor protective end caps are generally fixed with bolts, which complicates the installation process. Fixing requires tools such as screwdrivers and wrenches, increasing the difficulty of installation and disassembly. Furthermore, the need to tighten or loosen each bolt individually makes the entire operation time-consuming, thus reducing production efficiency.

[0004] Therefore, those skilled in the art have provided a protective end cap for micro motors to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a protective end cap for micro motors. In use, the end cap is inserted into the micro motor body via a connecting block that rotates, causing the groove of the connecting block to engage with the protrusion on the upper end of the micro motor body. Simultaneously, a limiting plate slides to limit the connecting block, and the positioning groove on the upper end of the limiting plate cooperates with the positioning pin on the upper end of the fixing frame, enabling a stable and rapid connection between the end cap and the micro motor body. This prevents loosening or detachment, ensuring the reliability of the motor during operation. Furthermore, the end cap can be installed without the need for complex tools, reducing installation time and labor costs, and improving production efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A protective end cap for a micro motor includes a micro motor body and an end cap. The micro motor body has evenly spaced sliding grooves on one outer side. Each sliding groove has a limiting plate inside. Each limiting plate has a positioning groove in the middle of one end face. A fixing frame is fixedly connected to both sides of the upper end of the micro motor body. Positioning pins are evenly spaced and fixedly connected to one end face of one fixing frame. An output shaft is located in the middle of the interior of the micro motor body. Protrusions are evenly spaced and fixedly connected to one inner side of the micro motor body. Connecting blocks are evenly spaced and fixedly connected to one end face of the end cap. Grooves are formed inside each connecting block. A support frame is fixedly connected inside the end cap, and a fan is rotatably connected inside the support frame.

[0008] With the above technical solution, when the end cap is in use, the connecting block extends into the micro motor body and rotates, so that the groove of the connecting block engages with the protrusion on the upper end of the micro motor body. At the same time, the limiting plate slides to limit the connecting block, and the positioning groove on the upper end of the limiting plate cooperates with the positioning pin on the upper end of the fixing frame, so that the end cap and the micro motor body can achieve a stable and fast connection, avoiding loosening or falling off, ensuring the reliability of the motor during operation. At the same time, the end cap can be installed without the use of complicated tools, reducing installation time and labor costs, and improving production efficiency.

[0009] Furthermore, a sealing ring is fixedly connected to one end face of the micro motor body, and the outer wall of the sealing ring is tightly fitted with the inner wall of the end cap.

[0010] The above technical solution effectively improves the sealing between the end cap and the micro motor body, prevents impurities from entering the motor, and improves the reliability and service life of the motor.

[0011] Furthermore, air inlets are evenly spaced on one side of the micro motor body, and air outlets are evenly spaced on the outside of the end cap.

[0012] The above technical solution optimizes the airflow path, allowing heat to be dissipated more quickly from the micro-motor body, further improving heat dissipation efficiency and keeping the micro-motor body within its optimal operating temperature range.

[0013] Furthermore, the inner wall of the fan is in close contact with the outer wall of the output shaft;

[0014] The above technical solution ensures efficient transmission between the fan and the output shaft, reduces energy loss, improves fan efficiency, and thus enhances overall heat dissipation performance.

[0015] Furthermore, all of the aforementioned positioning pins are slidably connected to the positioning groove, and each of the positioning pins has a pin on one side inside.

[0016] The above technical solutions improve installation efficiency, increase connection stability, and prevent loosening or detachment during use.

[0017] Furthermore, all of the connecting blocks extend into the interior of the micro motor body, and all of the grooves engage with and are connected to the protrusions.

[0018] The above technical solution ensures a firm connection between the end cap and the micro motor body, improves the stability and vibration resistance of the connection, and guarantees the reliable operation of the motor in complex environments.

[0019] Furthermore, one end face of each of the plurality of limiting plates is in close contact with one end face of the fixing frame on one side;

[0020] The above technical solution enhances the limiting effect, prevents relative displacement of the connecting block during operation, and ensures the stability and safety of the motor during long-term operation.

[0021] This utility model has the following beneficial effects:

[0022] 1. This utility model proposes a protective end cap for a micro motor. In use, the end cap extends into the micro motor body through a connecting block and rotates, causing the groove of the connecting block to engage with the protrusion on the upper end of the micro motor body. At the same time, a limiting plate slides to limit the connecting block, and the positioning groove on the upper end of the limiting plate cooperates with the positioning pin on the upper end of the fixing frame, so that the end cap and the micro motor body can achieve a stable and quick connection, preventing loosening or falling off and ensuring the reliability of the motor during operation. In addition, the end cap can be installed without the use of complicated tools, reducing installation time and labor costs and improving production efficiency.

[0023] 2. The present invention proposes a protective end cap for a micro motor. When in use, the fan inside the end cap is fitted onto the upper end of the output shaft, so that the fan can be directly driven by the output shaft when the micro motor is running. This keeps the fan speed consistent with the motor speed and, together with the air outlet, effectively dissipates internal heat, significantly improving heat dissipation efficiency. This helps the micro motor maintain its optimal operating temperature, avoids overheating caused by heat generated during operation, and extends the service life of the motor.

[0033] Reference Figure 1-6 The present invention provides a specific embodiment of a protective end cap for a micro motor, comprising a micro motor body 1 and an end cap 11. Sliding grooves 2 are evenly spaced on one side of the outer surface of the micro motor body 1. Limiting plates 3 are provided inside each of the sliding grooves 2. Positioning grooves 4 are provided in the middle of one side end face of each of the limiting plates 3. Fixing frames 5 are fixedly connected to both sides of the upper end of the micro motor body 1.

A support frame 13 is fixedly connected inside the end cap 11. A fan 14 is rotatably connected inside the support frame 13.

[0034] When in use, the end cap 11 extends into the micro motor body 1 via the connecting block 15 and rotates, causing the groove 16 of the connecting block 15 to engage with the protrusion 17 at the upper end of the micro motor body 1. At the same time, the limiting plate 3 slides to limit the connecting block 15, and the positioning groove 4 at the upper end of the limiting plate 3 cooperates with the positioning pin 6 at the upper end of the fixing frame 5, so that the end cap 11 and the micro motor body 1 can achieve a stable and quick connection, preventing loosening or falling off and ensuring the reliability of the motor during operation. In addition, the end cap 11 can be installed without the use of complicated tools, reducing installation time and labor costs and improving production efficiency.

[0035] A sealing ring 9 is fixedly connected to one end face of the micro motor body 1. The outer wall of the sealing ring 9 fits tightly against the inner wall of the end cover 11, effectively improving the sealing between the end cover 11 and the micro motor body 1, preventing impurities from entering the motor, and improving the reliability and service life of the motor. Air inlets 10 are evenly spaced on the outer side of the micro motor body 1, and air outlets 12 are evenly spaced on the outer side of the end cover 11, optimizing the airflow path and allowing heat to be dissipated more quickly from the micro motor body 1, further improving heat dissipation efficiency and keeping the micro motor body 1 within its optimal operating temperature range.

Next, the limiting plate 3 is pushed forward to limit the connecting block 15, and the positioning groove 4 at the upper end of the limiting plate 3 engages with the positioning pin 6 at the upper end of the fixing frame 5. Then, the pin 7 is inserted into one end of the positioning pin 6 to achieve a stable and quick connection between the end cap 11 and the micro motor body 1, preventing loosening or falling off and ensuring the reliability of the motor during operation. During the operation of the micro motor, the fan 14 inside the end cap 11 is fitted on the upper end of the output shaft 8 and driven by the output shaft 8, keeping the speed of the fan 14 consistent with the running speed of the motor, and effectively dissipating heat through the air outlet 12, significantly improving the heat dissipation efficiency, thereby helping the micro motor maintain the optimal operating temperature, avoiding overheating, and extending its service life.
