Description

Technical Field

[0001] This utility model belongs to the field of motor cover technology, specifically relating to a motor cover for a tricycle. Background Technology

[0002] Nowadays, most agricultural tricycles are electric vehicles. The motor of an electric vehicle consists of an internal motor body and an external motor housing, which includes the motor end cover.

[0003] The patent specification with publication number CN221487466U discloses a motor end cover, including a base plate, a side plate, a cover plate, and a surrounding plate. One end of the side plate is connected to the base plate, and the other end is connected to the cover plate. The surrounding plate is arranged along the periphery of the cover plate and includes a support part, an abutment part, and a boss part. The support part is connected to the periphery of the cover plate, and the abutment part and the boss part are respectively protruding from both ends of the support part. The abutment part is used to abut the end face of the outer shell, and the boss part abuts the inner sidewall of the outer shell. The support part is provided with a first receiving groove and a second receiving groove communicating with the first receiving groove. The first receiving groove is arranged near the abutment part and accommodates a sealing ring. The second receiving groove is arranged near the boss part.

[0004] The motor end cover is provided with a second receiving groove to collect the waste generated by the friction between the end cover and the outer shell, and a sealing ring is provided to seal the inner wall of the outer shell to improve the tightness of the connection between the end cover and the outer shell. The shortcoming of this technical solution is that the waste generated between the end cover and the outer shell is due to the different vibration frequencies of the outer shell and the end cover during the operation of the motor. The difference in vibration frequency between the outer shell and the end cover leads to collision, thereby generating debris. That is, the tightness of the connection between the end cover and the outer shell is low.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] The purpose of this utility model is to provide a motor cover for a tricycle. The technical problem to be solved is as follows: the existing motor end cover has a low degree of tightness when connected to the outer shell.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A tricycle motor cover includes a cover body, an outer plate at the top of the cover body, a plurality of reinforcing blocks uniformly fixedly connected to the outer plate and the cover body along the circumferential side, a shaft hole in the middle of the cover body penetrating the cover body and the outer plate, at least four locking holes uniformly arranged along the circumferential side of the cover body, a fixed shaft cylinder fixedly connected to the middle of the inner side of the cover body, a plurality of reinforcing strips between the fixed shaft cylinder and the cover body, and a positioning ring on one side of the cover body, the positioning ring having two constant pressure strip openings.

[0009] As a further embodiment of this utility model: the angle between the reinforcing block and the adjacent locking hole passing through the center line of the cover body is 30 degrees, and the two constant pressure strips are symmetrical about the central axis of the cover body.

[0010] As a further embodiment of this utility model: the cover body is provided with six locking ears evenly distributed along its circumferential side, and the locking holes correspond one-to-one with the locking ears.

[0011] As a further embodiment of this utility model: an inner cavity is provided on the inner side of the cover body, and a beveled ring is provided between the side wall of the inner cavity and the bottom surface of the inner cavity, and the outer side of the reinforcing strip is fixedly connected to the beveled ring.

[0012] As a further embodiment of this utility model: the inner side of the positioning ring is flush with the side wall of the inner cavity, the bottom surface of the cover is provided with a docking ring surface on the outer side of the positioning ring, and the bottom surface of the reinforcing block is flush with the docking ring surface.

[0013] As a further embodiment of this utility model: a bearing cavity is provided on the inner side of the fixed shaft cylinder, and three reinforcing shafts are evenly arranged on the circumferential side.

[0014] The beneficial effects of this utility model are:

[0015] By setting an outer plate on the outside of the cover, setting a reinforcing block between the outer plate and the cover, and setting multiple reinforcing strips on the inside of the cover, and setting a fixed shaft cylinder with a reinforcing shaft, the overall structural strength of the motor end cover is improved by setting multiple reinforcing structures. By setting six locking holes on the circumferential side of the cover and setting a positioning ring, the tightness of the connection between the motor end cover and the motor housing is improved. By evenly arranging the reinforcing blocks, reinforcing strips, locking ears and constant pressure strip openings, the mass distribution of the end cover is uniform, ensuring the overall stability of the end cover when the motor output shaft rotates.

[0016] After the end cap is connected to the motor housing, its high-strength structure, tight connection, and high stability during operation can effectively improve the tightness of the connection between the end cap and the housing, thereby preventing the end cap from vibrating at different frequencies relative to the housing when the motor vibrates. This effectively prevents ineffective collisions between the end cap and the housing, thus improving the structural stability of the motor housing and assisting in improving the effective power of the motor.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 scope of protection of the present utility model.

[0022] like Figure 1 and Figure 2 As shown, a tricycle motor cover includes a cover body 1, an outer plate 2 at the top of the cover body 1, three reinforcing blocks 3 evenly fixedly connected to the outer plate 2 and the cover body 1 along the circumferential side, a shaft hole 4 in the middle between the cover body 1 and the outer plate 2, a plurality of locking holes 5 evenly provided along the circumferential side of the cover body 1, a fixed shaft cylinder 6 fixedly connected to the middle of the inner side of the cover body 1, eight reinforcing strips 7 between the fixed shaft cylinder 6 and the circumferential side of the cover body 1, a positioning ring 8 in the inner side of the cover body 1, and two constant pressure strip openings 9 in the positioning ring 8;

[0023] It should be noted that the through-shaft hole 4 is used to extend the motor's rotating shaft to the outside of the motor to realize the driving function. A reinforcing ring plate is welded to the outer side of the top of the outer plate 2 to improve the support structure strength at the motor rotating shaft. The outer side and sides of the cover 1, outer plate 2, reinforcing block 3, and reinforcing ring plate are all electroplated with anti-corrosion paint to extend the service life of the motor cover. The motor cover is based on the basic structure of the cover 1 in the prior art, with the outer plate 2 for structural reinforcement and connected by the reinforcing block 3. The purpose of using the reinforcing ring plate is to improve its structural strength without significantly increasing the weight of the cover.

[0024] The angle between the reinforcing block 3 and the adjacent locking hole 5 and the line connecting the axis of the cover body 1 is 30 degrees. The two constant pressure slots 9 are symmetrical about the central axis of the cover body 1. That is, the mass of the motor cover is uniformly distributed. When used as a cover for the motor output shaft, the rotational stress of the motor shaft can be evenly distributed, thereby improving its stability during use and extending its service life. In addition, the constant pressure slots 9 are used to balance the air pressure inside and outside the motor to assist the motor in stable operation.

[0025] Six locking ears 10 are evenly fixedly connected to the circumferential side of the cover 1, and the locking holes 5 pass through the locking ears 10 and correspond one to one; that is, the locking holes 5 are evenly arranged on the outside of the cover 1. Compared with the locking holes 5 being arranged in the middle or inside of the cover 1, when it is connected to the motor housing, the bolts are independent of the cover 1 sealing surface, thereby ensuring the integrity and tightness of the cover when it is sealed.

[0026] An inner cavity 11 is provided on the inner side of the cover 1. An oblique connecting ring 12 is provided between the side wall of the inner cavity 11 and the bottom surface of the inner cavity 11. The outer side of the reinforcing strip 7 is fixedly connected to the oblique connecting ring 12.

[0027] The inner side of the positioning ring 8 is flush with the side wall of the inner cavity 11, and the bottom surface of the cover 1 is provided with a docking ring surface 13 on the outer side of the positioning ring 8. The bottom surface of the reinforcing block 3 is flush with the docking ring surface 13.

[0028] The inner side of the fixed shaft cylinder 6 is provided with a bearing cavity 14, and three reinforcing shafts 15 are evenly arranged on the circumferential side.

[0029] It should be noted that the oblique connecting ring 12 is used to improve the connection strength between the side wall and the bottom surface of the inner cavity 11, and the reinforcing strip 7 is used to improve the overall structural strength of the cover 1; the mating ring surface 13 is used to mate with the motor housing, and the bottom surface of the reinforcing block 3 increases the mating area of ​​the mating surface. Therefore, when all the locking holes 5 are locked, the connection surface between the cover 1 and the motor housing obtains sufficient support surface. With the locking of multiple locking holes 5, the tightness of the connection between the motor end cover and the motor housing is improved; in addition, when the motor end cover is connected to the housing, the positioning ring 8 is inserted into the inner side of the housing to position the connection. The bearing cavity 14 is used to install the bearing to power the rotation of the motor output shaft. At the same time, the use of the reinforcing shaft 15 can strengthen the support of the rotating part, thereby making the rotation of the motor rotating shaft more stable and reducing the vibration frequency.

[0030] In other words, by increasing the overall structural strength of the end cap, improving the docking accuracy and locking tightness, the tightness of the connection between the end cap and the motor housing is improved. This can effectively improve the synchronization between the end cap and the motor housing when the motor is running, reduce the mutual collision phenomenon caused by the end cap and the housing vibrating at different frequencies, thereby extending the service life of the end cap and improving the effective power of the motor during operation.

[0031] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
