[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] See also Figure 1 , Figure 2 The figure shows an end cover multi-channel heat dissipation motor, including a motor body 1 and an end cover structure 2 installed at the end of the motor body 1. The end cover structure 2 is used to seal the motor body 1. The end cover structure 2 includes an end cover body 201 fixedly connected to the motor body 1 by bolts, and the end cover body 201 is movably sleeved on the outer side of the output shaft of the motor body 1.

[0023] See also Figure 4 A plurality of heat dissipation fins 202 are fixedly welded to the outer side of the end cover body 201 . The heat dissipation fins 202 are aluminum fins. The heat dissipation fins 202 made of aluminum material are relatively light in weight.

[0024] See also Figure 4 A plurality of through holes 203 are provided on the heat dissipation fins 202, and the shape of the through holes 203 is circular. A plurality of fixing blocks 205 equidistantly distributed in a circumference are fixedly installed on the outer sides of the motor body 1 and the end cover body 201, and fixing bolts are installed on the fixing blocks 205.

[0025] See also Figure 3 , Figure 4 A plurality of reinforcing ribs 204 equidistantly distributed around a circle are arranged on the inner side of the end cover body 201, and the reinforcing ribs 204 and the end cover body 201 are an integrally formed structure, and the reinforcing ribs 204 can enhance the strength of the end cover body 201, and the support ring 3 is located on the inner side of the plurality of heat dissipation fins 202, and a gap is reserved between the support ring (3) and the end cover body (201), and the connection between the support ring 3 and the plurality of heat dissipation fins 202 is fixed welding.

[0026] The working principle of the end cover assisting the motor in heat dissipation is good: during the operation of the motor body 1, the temperature inside the motor body 1 rises, and the multiple heat dissipation fins 202 on the outside of the end cover body 201 exchange heat with the air. The multiple heat dissipation fins 202 increase the heat exchange area of ​​the end cover body 201, and the gas passes through the through holes 203 on the heat dissipation fins 202, so that the end cover body 201 increases the air flow channel, thereby further increasing the heat exchange area and heat exchange efficiency, so that the end cover body 201 assists the motor body 1 in heat dissipation. The effect is better, which is beneficial to the uniform temperature distribution inside the motor body 1, and avoids the uneven temperature distribution affecting the performance and life of the motor body 1.

[0027] Embodiment 2

[0028] See also Figure 2 This embodiment further explains the first embodiment. The support ring 3 is used to support the output shaft of the motor body 1. The support ring 3 is movably sleeved on the outer side of the output shaft of the motor body 1.

[0029] In this embodiment: during the rotation of the output shaft of the motor body 1, multiple heat dissipation fins 202 support the output shaft of the motor body 1 through the support ring 3, which is beneficial to enhancing the stability and bending resistance of the output shaft of the motor body 1, and the support ring 3 is located at the end of the heat dissipation fin 202 away from the end cover body 201, so that a gap is left between the support ring 3 and the end cover body 201 to facilitate the passage of gas, which is beneficial to the heat exchange between the heat dissipation fin 202 and the gas.

[0030] Embodiment 3

[0031] See also Figure 4 This embodiment further illustrates other embodiments. A plurality of balls 4 equidistantly distributed on a circumference are movably embedded in the inner side of the support ring 3. The balls 4 can reduce the friction between the support ring 3 and the output shaft of the motor body 1, and the connection between the balls 4 and the output shaft of the motor body 1 is rolling contact.

[0032] In this embodiment: when installing the end cover body 201, the personnel pass the output shaft of the motor body 1 through the end cover body 201 and the support ring 3 respectively. The output shaft of the motor body 1 contacts the multiple balls 4 on the inner side of the support ring 3, which can effectively reduce the friction between the support ring 3 and the output shaft of the motor body 1. It is not only convenient to install the end cover body 201, but also beneficial to reduce the wear of the output shaft during the rotation of the output shaft.
