Description

Technical Field

[0001] This utility model relates to the field of motors, specifically a self-heating side cover for motors. Background Technology

[0002] The electric motor is the core power component of an electric vehicle. It converts electrical energy into mechanical energy to drive the vehicle. Electric vehicle motors are mainly divided into two types: brushed motors (mainly composed of components such as stator, rotor, brushes, and commutator; the stator is the fixed magnetic field part, and the rotor is the part that rotates in the magnetic field) and brushless motors (the motor operates through electronic commutation; it mainly consists of stator, rotor, and electronic controller; the stator has windings, and the rotor has permanent magnets; the electronic controller controls the energizing sequence of the stator windings according to the rotor's position signal, causing the rotor to rotate under the action of the magnetic field).

[0003] However, the coils in the motor are prone to overheating during operation, and the motor's heat dissipation is poor. When the internal temperature is too high, the permanent magnet will lose its magnetism, affecting the performance. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a self-heating side cover for motors, thus solving the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a motor self-heating side cover, including a motor side cover, a transmission shaft hole is provided at the center of the motor side cover, reinforcing ribs are arranged in an annular array on the outer side of the transmission shaft hole located on the inner side wall of the motor side cover, heat dissipation fins are provided between two adjacent reinforcing ribs located on the inner side wall of the motor side cover, and mounting through holes are arranged in an annular array on the outer side of the motor side cover.

[0006] As a further embodiment of this utility model: a connecting shaft is installed inside the drive shaft hole, and an edge banding machine cover is provided on the outer side of the connecting shaft at the end away from the motor side cover. A first cooling fan is provided on the outer side of the connecting shaft corresponding to the inner side of the motor side cover, and a second cooling fan is provided on the outer side of the connecting shaft corresponding to the inner side of the edge banding machine cover.

[0007] As a further embodiment of this utility model: a rotor base is provided between the motor side cover and the sealing machine cover, magnetic sheets are installed in a circular array on the inner side wall of the rotor base, and a hub is provided on the outer side of the rotor base.

[0008] As a further improvement of this utility model, the convex arc of the blades of the first cooling fan and the second cooling fan are aligned in the same direction.

[0009] As a further improvement of this utility model, the motor side cover and the edge sealing machine cover have the same structural dimensions.

[0010] As a further improvement of this utility model, the heat dissipation fins and reinforcing ribs are integrally fixed with the motor side cover.

[0011] As a further embodiment of this utility model: the magnetic sheet is fixedly connected to the rotor base, and a motor stator is installed between the motor side cover and the edge sealing machine cover on the outside of the connecting shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By integrally fixing heat dissipation fins and reinforcing ribs on the inner side of both the motor side cover and the edge sealing machine cover, the heat transfer efficiency can be increased and the heat dissipation effect can be accelerated when the heat rises through the staggered arrangement of heat dissipation fins and reinforcing ribs.

[0014] The blades of the first and second cooling fans have the same convex arc, so the air outlet direction of the second cooling fan corresponds to the air inlet direction of the first cooling fan. This increases the airflow speed inside the device and accelerates the contact of heat with the motor cover. Attached Figure Description

[0020] 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 protection scope of the present utility model.

[0021] like Figure 1-4As shown, this embodiment provides a motor self-heating side cover, including a motor side cover 1. A drive shaft hole 4 is provided at the center of the motor side cover 1. Reinforcing ribs 3 are arranged in an annular array on the outer side of the drive shaft hole 4 and on the inner side wall of the motor side cover 1. Heat dissipation fins 2 are provided between two adjacent reinforcing ribs 3 on the inner side wall of the motor side cover 1. Both the heat dissipation fins 2 and the reinforcing ribs 3 are fixedly connected to the motor side cover 1. A mounting through hole 5 is arranged in an annular array on the outer side of the motor side cover 1.

[0022] like Figure 2-4 As shown, in this embodiment, a connecting shaft 9 is installed inside the transmission shaft hole 4. A sealing machine cover 101 is provided on the outer side of the connecting shaft 9 at the end away from the motor side cover 1. The motor side cover 1 and the sealing machine cover 101 have the same structural dimensions. A first cooling fan 10 is provided on the outer side of the connecting shaft 9 corresponding to the inner side of the motor side cover 1. A second cooling fan 102 is provided on the outer side of the connecting shaft 9 corresponding to the inner side of the sealing machine cover 101. The fan blades of the first cooling fan 10 and the second cooling fan 102 have the same convex direction. A rotor base 6 is provided between the motor side cover 1 and the sealing machine cover 101. Magnetic sheets 7 are installed in a ring array on the inner side wall of the rotor base 6. The magnetic sheets 7 are fixedly connected to the rotor base 6. A motor stator is installed on the outer side of the connecting shaft 9 between the motor side cover 1 and the sealing machine cover 101. A hub 8 is provided on the outer side of the rotor base 6.

[0023] The working principle of this utility model is as follows: During use, heat dissipation fins 2 and reinforcing ribs 3 are integrally fixed on the inner sides of both the motor side cover 1 and the edge sealing machine cover 101. When the heat rises, the staggered arrangement of the heat dissipation fins 2 and reinforcing ribs 3 increases the efficiency of heat transfer, accelerating the transfer of internal heat to the motor side cover 1 and the edge sealing machine cover 101 through the heat dissipation fins 2 and reinforcing ribs 3, and then dissipating it to the external environment. At the same time, during assembly, after the rotor is installed as a whole on the outside of the connecting shaft 9, the connecting shaft 9 is then installed inside the motor side cover 1 and the edge sealing machine cover 101 respectively. Inside the drive shaft hole 4 of the part, when the motor is working, the edge banding machine cover 101 and the motor side cover 1 rotate as a whole, which will drive the first cooling fan 10 and the second cooling fan 102 inside to work. Since the fan blades of the first cooling fan 10 and the second cooling fan 102 have the same arc protrusion direction, the air outlet direction of the second cooling fan 102 corresponds to the air inlet direction of the first cooling fan 10. This can increase the air circulation speed inside the device, accelerate the heat contact with the motor side cover 1, and facilitate the heat transfer to the outside through the heat dissipation fins 2 and the reinforcing ribs 3.
