Description

Technical Field

[0001] The utility model relates to the field of motors, in particular to a high-speed motor for an aviation trainer. Background Art

[0002] A Chinese patent with the publication number of CN217590440U discloses an assembly structure of a high-speed motor, including a stator, a front end cover and a rear end cover. The front end cover and the rear end cover are connected by four first connection bolts distributed circumferentially. A plurality of first connection ears are circumferentially arranged on the outer walls of the front end cover and the rear end cover at a distance from each other. The first connection ears on the front end cover and the rear end cover correspond to each other one by one. Bolt holes are provided on the first connection ears. Each group of corresponding first connection ears is fixedly connected by a first connection bolt. A plurality of second connection ears are circumferentially arranged on the outer walls of the front end cover and the rear end cover near each other, and the second connection ears on the front end cover and the rear end cover correspond to each other one by one. Bolt holes are provided on the second connection ears. Each group of corresponding second connection ears is fixedly connected by a second connection bolt.

[0003] The above structure can realize the fixation between the front end cover and the rear end cover by screwing a plurality of first connection bolts into the first connection ears on the front end cover and the rear end cover respectively, and screwing a plurality of second connection bolts into the second connection ears on the front end cover and the rear end cover respectively. However, during the fixation process of the front end cover and the rear end cover, it is necessary to manually keep a plurality of first connection ears and second connection ears on the front end cover and the rear end cover in one-to-one correspondence. Only at this time can the connection between the front end cover and the rear end cover be realized. If the first connection ear or the second connection ear on the front end cover is misaligned with the first connection ear or the second connection ear on the rear end cover during the fixation process, the position of the front end cover or the rear end cover needs to be adjusted, resulting in an increase in the amount of tools for workers and a low fixation efficiency. Summary of the Utility Model

[0004] Aiming at the shortcomings in the prior art that it is necessary to manually keep a plurality of first connection ears and second connection ears on the front end cover and the rear end cover in one-to-one correspondence to realize the connection between the front end cover and the rear end cover, resulting in an increase in the amount of tools for workers and a low fixation efficiency, the utility model provides a high-altitude motor for an aviation trainer with convenient fixation.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A high-speed motor for an aviation trainer, comprising a front end cover, a rear end cover, and a stator disposed between the two. A fixing component for fixing the two is provided between the front end cover and the rear end cover. The fixing component includes a plurality of insertion columns circumferentially arranged on the rear end cover. Through holes corresponding to the insertion columns in number and position are provided on the front end cover. After the insertion columns are inserted into the through holes, a part of the insertion columns penetrates out of the through holes. And a limiting component for limiting the position of the front end cover is provided at the end of the insertion column far from the rear end cover after the insertion column penetrates out of the through hole.

[0007] Adopting the above solution, when the front end cover and the rear end cover are fixed to each other, the plurality of insertion columns provided on the rear end cover can be inserted into the through holes on the front end cover. And the limiting component provided on the insertion column can abut against one end of the through hole far from the rear end cover after the insertion column passes through the through hole, so as to limit the position of the insertion column, reduce the probability of the insertion column retracting into the through hole, and thus reduce the probability of the front end cover and the rear end cover separating from each other. Since the fixation between the front end cover and the rear end cover only requires aligning the through holes on the front end cover with the insertion columns on the rear end cover and moving the front end cover towards the rear end cover direction, so that the insertion columns pass through the through holes, and making the limiting component on the insertion column limit the position of the insertion column, the installation of the front end cover and the rear end cover can be completed, and the installation is more convenient and time-saving.

[0008] Preferably, the limiting component includes a limiting block telescopically arranged on the outer wall of the insertion column and capable of abutting against the end of the through hole. A receiving groove for receiving the limiting block when the limiting block contracts is provided on the outer wall of the insertion column. A reset component for driving the limiting block to keep part of it protruding out of the receiving groove and at the same time driving the limiting block to protrude out of the receiving groove after contraction is provided between the receiving groove and the limiting block. An introducing component for driving the limiting block to automatically retract into the receiving groove when the insertion column is inserted into the through hole is provided on the limiting block.

[0009] Adopting the above solution, the limiting block telescopically arranged on the outer wall of the insertion column can protrude out of the receiving groove partially after the insertion column passes through the through hole. And the surface of the limiting block protruding out of the receiving groove partially can abut against the side of the through hole far from the rear end cover, so as to reduce the automatic retraction of the insertion column into the through hole and reduce the probability of the front end cover and the rear end cover separating from each other. The provided introducing component can drive the limiting block to retract into the receiving groove when the insertion column is inserted into the through hole, so that the insertion column can be smoothly inserted into the through hole. The provided reset component can be used to push the limiting block retracted into the receiving groove to protrude out of the receiving groove partially, so as to limit the position of the insertion column and reduce the probability of the insertion column retracting into the through hole.

[0010] Preferably, the reset component includes a spring provided between the bottom of the receiving groove and one end of the limiting block close to the receiving groove, with both ends connected to the two respectively.

[0011] With the above solution, the spring provided can drive the limiting block provided in the receiving groove to be partially extended outside the receiving groove. At the same time, the spring can also push the limiting block to extend outside the receiving groove after the limiting block retracts into the receiving groove under the action of the guiding component, so as to reset the limiting block.

[0012] Preferably, the guiding component includes a guiding inclined surface provided on the limiting block, and the guiding inclined surface is inclined and decreases from the end close to the rear end cover to the end far from the rear end cover.

[0013] With the above solution, by providing a guiding inclined surface on the limiting block, when the plugging post is inserted into the through hole, it abuts against the inner wall of the through hole, thereby driving the limiting block to retract into the receiving groove when the plugging post is inserted into the through hole, so that the plugging post can be smoothly inserted into the through hole.

[0014] Preferably, at least two groups of the limiting components are provided and are evenly distributed on the outer wall of the plugging post.

[0015] With the above solution, evenly providing at least two groups of limiting components on the outer wall of the plugging post can reduce the probability of the plugging post automatically retracting into the through hole, thereby reducing the probability of the front end cover and the rear end cover separating when the motor is in use. At the same time, it can also make the force transmitted from the limiting block to the plugging post more uniform, thereby increasing the service life of the plugging post.

[0016] Preferably, an anti - detachment component for reducing the separation of the front end cover and the rear end cover caused by the automatic retraction of the limiting block into the receiving groove is provided on the limiting block.

[0017] Preferably, the anti - detachment component includes a through groove horizontally provided on the limiting block and a limiting plate inserted into the through groove and having both ends extending out of the through groove. When the limiting block is partially extended outside the receiving groove, the bottom of the through groove is higher than the outer wall of the plugging post or flush with the outer wall of the plugging post.

[0018] With the above solution, by providing the limiting plate, when the limiting block extends outside the receiving groove, it is inserted into the through groove until both ends of the limiting plate are partially extended outside the through groove. At this time, the limiting plate can abut against the outer wall of the plugging post, making the limiting block unable to retract into the receiving groove, thereby reducing the probability of the front end cover and the rear end cover separating.

[0019] Due to the adoption of the above technical solutions, the utility model has remarkable technical effects: when the front end cover and the rear end cover are fixed to each other, a plurality of insertion columns arranged on the rear end cover can be inserted into the through holes on the front end cover, and the limiting components arranged on the insertion columns can abut against one end of the through hole far away from the rear end cover after the insertion columns pass through the through holes, so as to limit the positions of the insertion columns, reduce the probability of the insertion columns retracting into the through holes, and thus reduce the probability of the front end cover and the rear end cover separating. Since the fixation between the front end cover and the rear end cover only requires aligning the through holes on the front end cover with the insertion columns on the rear end cover and moving the front end cover towards the rear end cover direction, enabling the insertion columns to pass through the through holes and making the limiting components on the insertion columns limit the positions of the insertion columns, the installation of the front end cover and the rear end cover can be completed, and the installation is more convenient and time-saving.

[0029] The present utility model will be further described in detail below in conjunction with the drawings and embodiments.

[0030] Embodiment

[0031] A high-speed motor for an aviation trainer, refer toFigure 1-2 , Figure 7-Figure 8 , including a front end cover 1, a rear end cover 2 and a stator 3 disposed therebetween. A fixing member for fixing the two is provided between the front end cover 1 and the rear end cover 2. The fixing member includes a plurality of insertion posts 4 circumferentially arranged on the rear end cover 2. Through holes 5 corresponding to the insertion posts 4 in number and position are provided on the front end cover 1. In this embodiment, four insertion posts 4 and through holes 5 are respectively provided. After the insertion posts 4 are inserted into the through holes 5, a part of them penetrates out of the through holes 5. And a limiting member for limiting the position of the front end cover 1 when the insertion posts 4 penetrate out of the through holes 5 is provided at one end of the insertion posts 4 away from the rear end cover 2. At least two groups of limiting members are provided and evenly distributed on the outer wall of the insertion posts 4. In this embodiment, two groups of limiting members are provided and symmetrically arranged on the outer wall of the insertion posts 4.

[0032] Reference Figure 1-Figure 6 , the limiting member includes a limiting block 6 telescopically arranged on the outer wall of the insertion post 4 and capable of abutting against the end of the through hole 5. A receiving groove 7 for receiving the limiting block 6 when the limiting block 6 contracts is provided on the outer wall of the insertion post 4. A reset member for driving the limiting block 6 to keep partially protruding out of the receiving groove 7 and at the same time driving the limiting block 6 to protrude partially out of the receiving groove 7 after contraction is provided between the receiving groove 7 and the limiting block 6. An introducing member for driving the limiting block 6 to automatically retract into the receiving groove 7 when the insertion post 4 is inserted into the through hole 5 is provided on the limiting block 6. The reset member includes a spring 8 connected to the bottom of the receiving groove 7 and one end of the limiting block 6 close to the receiving groove 7 at both ends. The introducing member includes an introducing inclined surface 9 provided on the limiting block 6. The introducing inclined surface 9 is inclined and decreases from the end close to the rear end cover 2 to the end away from the rear end cover 2.

[0033] Reference Figure 3-Figure 6 , an anti - detachment member for preventing the front end cover 1 and the rear end cover 2 from separating due to the automatic retraction of the limiting block 6 into the receiving groove 7 is provided on the limiting block 6. The anti - detachment member includes a through groove 10 horizontally provided on the limiting block 6 and a limiting plate 11 inserted into the through groove 10 and protruding out of the through groove 10 at both ends. When the limiting block 6 partially protrudes out of the receiving groove 7, the bottom of the through groove 10 is higher than or flush with the outer wall of the insertion post 4.

[0034] Specific fixing process: When the front end cover 1 needs to be fixed to the rear end cover 2, first, move the front end cover 1 so that the four through holes 5 on the front end cover 1 are aligned with the four insertion posts 4 on the rear end cover 2. Then, move the front end cover 1 in the direction close to the rear end cover 2 so that the insertion posts 4 on the rear end cover 2 are inserted into the through holes 5 on the front end cover 1. When the insertion posts 4 are inserted into the through holes 5, the guiding slopes 9 on the symmetrically arranged limiting blocks 6 on the outer wall of the insertion posts 4 will abut against the inner wall of the through holes 5. As the insertion posts 4 penetrate deeper, the guiding slopes 9 will be squeezed against the inner wall of the through holes 5. At this time, the limiting blocks 6 will be squeezed by the guiding slopes 9 and retract into the receiving grooves 7, and the springs 8 will be compressed. At this time, the insertion posts 4 are inserted into the through holes 5. After the front end cover 1 moves to the designated position, that is, when the limiting blocks 6 on the insertion posts 4 protrude from the other end of the through holes 5, at this time, the limiting blocks 6 will lose the extrusion of the inner wall of the through holes 5, and the springs 8 arranged between the limiting blocks 6 and the receiving grooves 7 will recover, thereby pushing a part of the limiting blocks 6 to protrude out of the receiving grooves 7. At this time, the limiting blocks 6 that partially protrude out of the receiving grooves 7 can abut against the side of the through holes 5 far from the rear end cover 2, so as to limit the position of the insertion posts 4, thereby realizing the fixation of the front end cover 1 and the rear end cover 2, reducing the probability of the front end cover 1 and the rear end cover 2 being separated. Finally, insert the limiting plate 11 into the through slots 10 on the limiting blocks 6, reducing the probability of the limiting blocks 6 automatically retracting into the receiving grooves 7 during the use of the motor, thereby further reducing the probability of the front end cover 1 and the rear end cover 2 being separated.

[0035] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
