Description

Technical Field

[0001] This invention relates to the field of motor technology, and in particular to a motor that is easy to maintain. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Its main function is to generate driving torque, serving as a power source for electrical appliances or various machines. Electric motors are widely used in various fields, such as industry, transportation, and household appliances, and are an indispensable part of modern life.

[0003] In practical use, existing motors are generally fixed to a supporting object using bolts. However, during operation, the motor vibrates, causing these bolts to loosen. Loose bolts intensify vibration, affecting the motor's stability and operating efficiency. Prolonged exposure to loose bolts can also lead to motor damage and safety accidents. Furthermore, because existing motors are fixed to the supporting object with multiple bolts, tools are needed to loosen and remove these bolts before the motor can be detached, reducing the convenience of disassembly and maintenance.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1: Please refer to Figures 1 to 11 :

[0039] This invention proposes a maintenance-friendly motor, comprising: a motor body 1; a motor base 101 at the bottom of the motor body 1, with four T-shaped sliding strips evenly arranged on the bottom surface of the motor base 101, and a mounting seat 102 slidably connected to the bottom of the motor base 101 via the four T-shaped sliding strips; two mounting plates 103 on both the left and right sides of the mounting seat 102, each mounting plate 103 having a mounting hole, and a fixing bolt 2 being movably inserted into each mounting hole; a limiting plate 106 fixedly connected to the front end of the mounting seat 102, and two one-way locking mechanisms 3 symmetrically installed on the front end of the limiting plate 106; and a fan cover 1010 installed at the rear end of the motor body 1, with a limiting mechanism 4 on both the left and right sides of the fan cover 1010 for limiting the fan cover 1010.

[0040] Each mounting plate 103 has a fixedly installed annular one-way limiting plate 104 on its upper end face, and each annular one-way limiting plate 104 has one-way limiting teeth 105 arranged in an annular array on its upper end face. The edge of one side of the upper end face of each one-way limiting teeth 105 is chamfered to cooperate with the rounded corner of one side of the lower end face of the one-way limiting plate 204.

[0041] Two plug-in plates 107 are fixedly connected to the front end face of the motor base 101, and each plug-in plate 107 has a rectangular plug-in through hole 108 on its right end face. The two plug-in plates 107 can pass through the limiting plate 106.

[0042] The upper surface of the mounting base 102 is provided with four T-shaped sliding grooves evenly spaced. The four T-shaped sliding grooves on the mounting base 102 are used to slide and connect with the four T-shaped sliding strips on the bottom surface of the motor base 101. After the motor base 101 and the mounting base 102 are slidably connected, the mounting base 102 will be limited in the vertical direction.

[0043] The rear side of the outer peripheral surface of the motor body 1 is provided with four slide rails 109 in a circular array, and each slide rail 109 is provided with a T-shaped slide groove. The T-shaped slide grooves on the left and right slide rails 109 are provided with a limiting insertion hole 1012. The inner peripheral surface of the fan cover 1010 is provided with four T-shaped sliding blocks 1011 in a circular array. The four T-shaped sliding blocks 1011 are used to slide and connect with the T-shaped slide grooves on the four slide rails 109.

[0044] The fixing bolt 2 is externally fixedly connected to an annular limiting block 201, and the outer circumferential surface of the annular limiting block 201 has two strip-shaped grooves 203; the tightening direction of the fixing bolt 2 is clockwise.

[0045] An annular sliding plate 202 is slidably connected to the outside of the fixing bolt 2, and the annular sliding plate 202 is located above the annular limiting block 201; two one-way limiting plates 204 are fixedly connected in an annular array on the bottom end face of the annular sliding plate 202, and the two one-way limiting plates 204 can be slidably connected to two strip-shaped sliding grooves 203; one edge of the lower end face of each one-way limiting plate 204 is rounded; an annular limiting plate 205 is fixedly connected to the outside of the fixing bolt 2 at the bottom of the hexagonal rotating block, and a spring is sleeved between the annular limiting plate 205 and the annular sliding plate 202 on the outside of the fixing bolt 2; when the one-way limiting plate 204 is in the one-way limiting state... The lower end of the one-way limiting plate 204 is in close contact with the upper surface of the annular one-way limiting plate 104, and the one-way limiting plate 204 is located between two adjacent one-way limiting teeth 105, thereby effectively preventing the fixing bolt 2 from loosening and avoiding the situation where the vibration is aggravated and affects the stability and operating efficiency of the motor body 1; by pulling the annular sliding plate 202 upward, and then rotating the annular sliding plate 202 from 45 degrees to 90 degrees, the annular sliding plate 202 and the one-way limiting plate 204 can be locked on the upper part of the annular limiting block 201. At this time, the fixing bolt 2 can be easily rotated counterclockwise, which facilitates the disassembly of the fixing bolt 2.

[0046] The one-way locking mechanism 3 includes a rectangular sliding shell 301, a rectangular sliding block 302, a trapezoidal plug-in block 303, and a pull block 304. The rectangular sliding shell 301 is fixedly installed on the front end face of the limiting plate 106, and the rectangular sliding block 302 is slidably connected inside the rectangular sliding shell 301. The head end face of the rectangular sliding block 302 is provided with a trapezoidal plug-in block 303 that penetrates the head of the rectangular sliding shell 301. A spring is provided inside the rectangular sliding shell 301 at the tail end of the rectangular sliding block 302. The front end face of the rectangular sliding block 302 is fixedly connected with the pull block 304, and the pull block 304 is provided with a handle. When the two one-way locking mechanisms 3 are in the locking and limiting state, the two trapezoidal plug-in blocks 303 are respectively plugged into the two rectangular plug-in through holes 108. The one-way locking mechanism 3 is used to limit the one-way locking mechanism 3.

[0047] Example 2, based on Example 1, such as Figure 1 , Figure 4 and Figure 10As shown, the limiting mechanism 4 includes a limiting housing 401, a rectangular slider 402, a rectangular sliding plate 403, a pull handle 404, a limiting rod 405, an L-shaped limiting block 406, a pad 407, a hexagonal sliding column 408, and a spring guide rod 409. The limiting housing 401 is fixedly connected to the front side of the outer periphery of the fan cover 1010, and the rectangular slider 402 is slidably connected inside the limiting housing 401. The limiting rod 405, which penetrates the head of the limiting housing 401, is fixedly connected to the head end face of the rectangular slider 402, and the spring guide rod 409, which penetrates the tail of the limiting housing 401, is provided on the tail end face of the rectangular slider 402. A spring is sleeved on the outside of the spring guide rod 409 inside the limiting housing 401. The pad 407 is fixedly connected to the upper end face of the rectangular slider 402. Furthermore, a hexagonal sliding column 408 is fixedly connected to the upper end of the pad 407, and a circular limiting plate is provided at the upper end of the hexagonal sliding column 408. A rectangular sliding plate 403 is slidably connected to the outside of the hexagonal sliding column 408, and a pull handle 404 is fixedly connected to the rectangular sliding plate 403. A spring is sleeved on the outside of the hexagonal sliding column 408 between the rectangular sliding plate 403 and the circular limiting plate. An L-shaped limiting block 406 is fixedly connected to the upper end of the limiting housing 401. When the two limiting mechanisms 4 are in the limiting state, the two limiting rods 405 are respectively inserted into the two limiting holes 1012. Through the cooperation of the slide rail 109, the limiting holes 1012 and the limiting mechanism 4, the fan cover 1010 can be removed from the rear end of the motor body 1 without the use of tools, which is more convenient.

[0048] The working principle of this embodiment is as follows: In use, first, the mounting base 102 is placed on the supporting object. Then, the four fixing bolts 2 are movably inserted into the four mounting plates 103. Next, the four fixing bolts 2 are tightened clockwise into the nuts on the supporting object. The nuts on the supporting object are fixed together with the supporting object. When the fixing bolts 2 are tightened clockwise, the bottom surface of the annular limiting block 201 is in close contact with the upper surface of the mounting plate 103. At this time, the lower end of the one-way limiting plate 204 is in close contact with the upper surface of the annular one-way limiting plate 104. The one-way limiting plate 204 is located between two adjacent one-way limiting tooth blocks 105. Since the lower end face of the one-way limiting plate 204 is rounded and the upper end face of each one-way limiting tooth block 105 is chamfered, and the one-way limiting plate 204 is slidably connected inside the strip groove 203, the annular limiting block 201 and the fixing bolt 2 can only rotate clockwise and cannot rotate counterclockwise, thus effectively preventing the fixing bolt 2 from loosening.

[0049] When the motor body 1 needs to be disassembled for maintenance, simply pull the handles on the two pull blocks 304 simultaneously in opposite directions. This will move the two rectangular sliding blocks 302 and the two trapezoidal plug-in blocks 303 in opposite directions, causing the two trapezoidal plug-in blocks 303 to be pulled out from the two rectangular plug-in through holes 108 respectively. This will cause the two plug-in plates 107 to lose their limiting function. Then, push the motor body 1 backward to make the motor base 101 slide away from the mounting base 102. After the motor base 101 slides away from the upper part of the mounting base 102, the motor body 1 is disassembled.

[0050] When it is necessary to remove the fan cover 1010 from the rear end of the motor body 1, simply move the pull handle 404 upward so that the pull handle 404 is higher than the L-shaped limit block 406. Then move the pull handle 404 towards the tail end of the spring guide rod 409, so that the pull handle 404, along with the rectangular sliding plate 403, hexagonal sliding column 408, pad 407, rectangular slider 402 and limit rod 405, moves towards the tail end of the spring guide rod 409, thereby pulling the limit rod 405 out of the limit hole 1012. Then, lock the pull handle 404 at the lower rear side of the L-shaped limit block 406 to limit the limit rod 405. After the two limit rods 405 are pulled out from the two limit holes 1012, the fan cover 1010 loses its limiting function at the rear end of the motor body 1. Finally, the fan cover 1010 can be removed from the rear end of the motor body 1.
