[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0025] Please refer to Figures 1-4 The utility model provides a kind of technical scheme: a box structure for automobile window motor, including box 12, comprising,

[0026] Mounting hole 8, number is three, and is equilateral triangle shape equidistantly connected in one side of box 12;

[0027] Stiffener 9, at least ten, is connected in the side of box 12 away from mounting hole 8, and is equidistantly arranged in circumferential array;

[0028] Brush holder 2, it is set on box 12, and it is used with multiple stiffener 9 cooperation and constitutes vent hole 10.

[0029] It needs to be explained that box 12 is made of PBT material or plastic material, and its appearance is polished.

[0030] Specific implementation, box 12 one side equilateral triangle shape equidistantly distributed three mounting holes 8, mainly for the motor box 12 is firmly installed in the specific position of automobile. The layout mode of equilateral triangle can provide stable support structure, ensure that box 12 still maintains fixed position when being subjected to vibration and external force in the process of automobile driving, at least ten stiffener 9 is equidistantly arranged in circumferential array in the side of box 12 away from mounting hole 8. These stiffener 9 enhances the structural strength of box 12, when internal stress is generated when motor is operated, or vibration in the process of automobile driving is transmitted to box 12, stiffener 9 can disperse these stress and vibration, prevent box 12 from deforming due to stress, when internal electric energy is converted into mechanical energy in the process of motor operation, heat will be generated, if heat can not be dissipated in time, it will affect the performance and life of motor. The role of vent hole 10 is to realize the circulation of air inside and outside motor. When motor works, internal air is heated and rises, is discharged through vent hole 10, while relatively low temperature air from other positions will flow in, forms air convection.

[0031] Reference Figure 3 Box 12 is connected with gear box cover 3, gear box cover 3 is rotationally connected with worm wheel 1, box 12 is rotationally connected with main shaft, main shaft is connected with worm 5, worm 5 is meshed with worm wheel 1.

[0032] In specific implementation, it is necessary to point out that the inner diameter of the gear box cover 3 matched with the worm wheel 1 is larger than the outer diameter of the worm wheel 1.

[0033] In specific implementation, the worm 5 is arranged to be engaged with the worm wheel 1, and the rotation of the worm 5 can drive the worm wheel 1 to rotate in the gear box cover 3. The engagement transmission of the worm and the worm wheel 1 has a unique property, the helical structure of the worm 5 interacts with the gear teeth of the worm wheel 1, which can realize a large transmission ratio, and the gear box cover 3 is connected with the box body 12 to provide a relatively closed space for the engagement of the worm wheel 1 and the worm 5, thereby playing a protection and support role. It can prevent dust, sundries and the like from entering the engagement area.

[0034] Referring to Figure 3 , the rotor is rotatably connected in the box body 12, and the brush holder 2 is connected to the rotor.

[0035] In specific implementation, the brush holder 2 is connected to the rotor, and its main function is to provide continuous current supply for the rotor winding.

[0036] Referring to Figure 3 , the bearing body 7 is connected to the main shaft, and the bearing sleeve 4 is rotatably connected to one end of the main shaft.

[0037] In specific implementation, the bearing body 7 is tightly connected to the main shaft, which provides stable support for the high-speed rotating main shaft, and the bearing sleeve 4 rotatably connected to one end of the main shaft plays a role of axial positioning for the main shaft. It limits the movement of the main shaft in the axial direction, and the bearing sleeve 4 also provides a certain degree of protection for the bearing body 7. It can prevent dust, moisture and other impurities from entering the bearing interior, avoid the abrasion or corrosion of these impurities to the rolling elements and raceways, thereby prolonging the service life of the bearing.

[0038] Referring to Figure 3 , the main shaft is connected to the plum blossom fork 6 at the end away from the bearing sleeve 4, and the plum blossom fork 6 is rotatably connected in the box body 12.

[0039] In specific implementation, the plum blossom fork 6 is tightly connected to the end of the main shaft away from the bearing sleeve 4, and can directly receive the rotating power transmitted by the main shaft. Since vibrations will be generated during the driving of the automobile, and the motor will also generate certain vibrations during operation, the rotatable connection mode of the plum blossom fork 6 and its own elastic deformation capability depending on the material properties and structural design can buffer and absorb these vibrations and impacts to a certain extent.

[0040] Referring to Figure 3 , the box body 12 is connected with the positioning hole 11 on the side close to the reinforcing rib 9.

[0041] In the installation process of the automobile window shaking motor, the positioning hole 11 provides an accurate positioning reference for the installation of the motor at a specific position of the automobile. On the automobile manufacturing or assembly line, the workers can quickly and accurately determine the position of the motor by inserting a positioning pin, bolt or other positioning device into the positioning hole 11.

[0042] In the second embodiment, to avoid the generation of a large amount of heat by the components in the box 12 during use, which would cause the components to work under overload, movable heat dissipation fins are arranged on the surface of the reinforcing rib 9 perpendicular to the direction of the reinforcing rib 9. These heat dissipation fins are connected to the reinforcing rib 9 through a rotating shaft and a torsional spring, and a micro heat dissipation fan is arranged in the box 12. When the micro heat dissipation fan is started, the pressure generated by the air flow acts on the heat dissipation fins, causing them to rotate around the rotating shaft and expand the heat dissipation area. When the fan stops running, the torsional spring causes the fins to return to the initial position, reducing the occupation of space and thus better dissipating heat from the components in the box 12.

[0043] At the same time, a rotary foreign matter filter screen can be installed at the inlet of the air vent hole 10. The filter screen is in the shape of a cylinder and has a central shaft connected to the driving end of the micro heat dissipation fan. When the micro heat dissipation fan is started by the motor, the filter screen rotates synchronously. The airflow generated by the micro heat dissipation fan dissipates heat inside the box 12 and forms a certain air pressure on the surface of the filter screen, which helps the filter screen to shake off the attached dust and impurities. In this way, the self-cleaning function of the filter screen is also activated simultaneously while dissipating heat, realizing the linkage of heat dissipation and filtration.

[0044] Further, to avoid unnecessary wear and energy consumption caused by continuous rotation of the filter screen for a long time, an intermittent cleaning function can be realized through a control circuit. During the continuous operation of the micro heat dissipation fan, the control circuit temporarily increases the rotation speed of the driving motor at a preset time interval, for example, every 5-10 minutes, so that the filter screen can more effectively shake off the dust and impurities under high-speed rotation. After a few seconds of high-speed rotation, the motor returns to the normal fan driving speed, and the filter screen continues to rotate at a lower speed, which can ensure the cleaning effect of the filter screen while reducing energy consumption and wear.

[0045] At the same time, a detachable collection box is arranged below the filter screen to collect the foreign matter shaken off, which facilitates regular cleaning and effectively prevents foreign matter from entering the motor interior while realizing the self-cleaning function and ensuring the smoothness of the air vent.

[0046] Working principle: box 12 side isosceles triangle-shaped equidistant distribution of three mounting holes 8, mainly for the motor box 12 is firmly installed in a specific location of the car. Isosceles triangle layout can provide a stable support structure to ensure that the box 12 in the process of driving the car to withstand the shock and external forces, still maintain a fixed position, in the box 12 away from the mounting hole 8, at least ten reinforcing ribs 9 are arranged in a circular array equidistant. These reinforcing ribs 9 enhance the structural strength of the box 12, when the motor runs the internal stress, or the shock during driving the car to the box 12, reinforcing ribs 9 can disperse these stresses and vibrations, prevent the box 12 due to stress and deformation, the motor in the process of running, the internal electrical energy into mechanical energy will produce heat, if the heat can not be timely, will affect the performance and life of the motor. The role of the vent 10 is to realize the flow of air inside and outside the motor. When the motor is working, the internal air is heated and rises, and the vent 10 is discharged, while the relatively low temperature of the outside air will flow from other locations, forming a convection current.
