[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-3The utility model provides a technical solution: a structural device for improving the protection level of a motor, comprising a motor body 1, the motor body 1 comprising a motor casing 2, a motor rear end cover 3 and a motor brake 8, the upper surface of the motor casing 2 is provided with a motor rear end cover 3, the inner side surfaces of the motor casing 2 and the motor rear end cover 3 are provided with a first sealing ring 4, the outer surface of the motor rear end cover 3 is provided with a screw terminal 5, the outer surface of the screw terminal 5 is fixedly sleeved with a first sealing gasket 6 and a second sealing gasket 7, the first sealing gasket 6 and the second sealing gasket 7 are respectively located on the inner side and the outer side of the motor rear end cover 3, the first sealing gasket 6 and the second sealing gasket 7 are respectively tightly attached to the inner wall and outer surface of the motor rear end cover 3, the upper surface of the motor rear end cover 3 is provided with a motor brake 8, the motor brake 8 adopts a specially customized closed structure, which can improve the protection effect, and the motor brake 8 and the inner side surface of the motor rear end cover 3 are provided with a second sealing ring 9.

[0021] By setting the first sealing ring 4, the sealing between the motor housing 2 and the motor rear end cover 3 can be increased. Secondly, due to the setting of the first sealing gasket 6 and the second sealing gasket 7, the sealing between the screw terminal 5 and the motor rear end cover 3 can be increased. Then, due to the setting of the second sealing ring 9, the sealing between the motor rear end cover 3 and the motor brake 8 can be increased. Finally, the motor lead adopts a waterproof connector 10 structure to achieve a waterproof function. At this point, sealing and waterproofing treatment is achieved between multiple groups of components on the motor body 1. Therefore, the motor body 1 is not easy to be infiltrated by water, and it is not easy to cause damage to the motor body 1, thereby ensuring the performance of the motor body 1.

[0022] The sizes and shapes of all components in this structure are not specifically limited here and need to be produced according to actual conditions.

[0023] In order to improve the overall protection of the device, the present invention provides a waterproof connector 10 on the outer surface of the rear end cover 3 of the motor. Compared with the motor lead wire guard coil commonly used on IP54 motors, this solution uses a waterproof connector 10 instead, so that it can achieve the waterproof function and improve the overall protection of the device.

[0024] In order to facilitate the staff to install the first sealing ring 4 into the interior of the motor rear end cover 3, the utility model provides a first installation groove on the lower surface of the motor rear end cover 3. The inner diameter of the first installation groove is adapted to the outer diameter of the first sealing ring 4 and has the same size, which makes it convenient for the staff to install the first sealing ring 4 into the interior of the motor rear end cover 3. At the same time, because of the same size, when the first sealing ring 4 is placed in the interior of the first installation groove, the first sealing ring 4 and the first installation groove will be installed tightly, which indirectly improves the overall protection of the device.

[0025] In order to facilitate the staff to place the second sealing ring 9 into the interior of the motor brake 8, the utility model provides a second mounting groove on the lower surface of the motor brake 8. The inner diameter of the second mounting groove is adapted to the outer diameter of the second sealing ring 9 and has the same size, which makes it convenient for the staff to place the second sealing ring 9 into the interior of the motor brake 8. At the same time, because of the same size, when the second sealing ring 9 is placed into the interior of the second mounting groove, the second sealing ring 9 and the second mounting groove will be installed tightly, which indirectly improves the overall protection of the device.

[0026] In order to improve the sealing performance of the first sealing ring 4, the first sealing gasket 6, the second sealing gasket 7 and the second sealing ring 9 when they are in use, the utility model uses rubber as the manufacturing material of the first sealing ring 4, the first sealing gasket 6, the second sealing gasket 7 and the second sealing ring 9. The sealing parts made of rubber material have good sealing performance and can effectively prevent the entry of liquid, gas and dust, thereby improving the sealing performance of the first sealing ring 4, the first sealing gasket 6, the second sealing gasket 7 and the second sealing ring 9 when they are in use. At the same time, they also have good elasticity and deformation ability and can adapt to sealing surfaces of different shapes and sizes. Secondly, they have good wear resistance and fatigue resistance and can extend service life. Finally, the cost is relatively low and they are economical and affordable. The manufacturing materials of the above-mentioned groups of sealing structures are not limited to rubber, and better and more suitable materials can also be used.

[0027] When in use, first, a first mounting groove is opened on the lower surface of the motor rear end cover 3. When the staff installs it between the motor casing 2 and the motor rear end cover 3, the first sealing ring 4 is installed into the inside of the first mounting groove, which can enhance the sealing effect between the motor casing 2 and the motor rear end cover 3. Secondly, a first sealing gasket 6 and a second sealing gasket 7 are sleeved on the outer surface of the screw terminal 5. The first sealing gasket 6 and the second sealing gasket 7 can be respectively tightly attached to the inner wall and outer surface of the motor rear end cover 3 to enhance the sealing between the screw terminal 5 and the motor rear end cover 3. Then, a second mounting groove is opened on the lower surface of the motor brake 8. Then the staff puts the second sealing ring 9 into the inside of the second mounting groove and then installs it between the motor rear end cover 3 and the motor brake 8 to enhance the sealing between the motor rear end cover 3 and the motor brake 8. At the same time, the motor brake 8 is specially customized to develop a closed structure. Then, a waterproof connector 10 is used at the motor lead to achieve a waterproof function. At this point, the sealing process between multiple groups of structures inside the motor body 1 is completed to improve the overall protection.

[0028] Subsequently, when the staff conducted an airtightness test on the motor body 1 at a later stage, they found that the pressure maintenance coefficient of the motor body 1 could reach 99.19% after 30 seconds of pressure maintenance. Therefore, the protection level of the motor body 1 meets the IP67 standard.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
