[0028] Embodiment 1

[0029] Referring to FIG. 1 , this embodiment provides a motor anti-rotation fixing base, comprising: a connecting member 1, a placing platform 2 and a rotating shaft 4. The connecting member 1 comprises a first connecting plate 11 and a second connecting plate 12, and the first connecting plate 11 is connected to the second connecting plate 12 at a certain angle. In this embodiment, the first connecting plate 11 is perpendicular to the second connecting plate 12, and an edge of the second connecting plate 12 extends upward in a direction perpendicular to the second connecting plate 12. The first connecting plate 11 has a first connecting portion 111 for connecting to the vehicle body, and the second connecting plate 12 has a second connecting portion 121 for connecting to the vehicle body. The placing platform 2 is used to install the motor 3. The placing platform 2 is connected to the first connecting plate 11, and the placing platform 2 is arranged parallel to the second connecting plate 12. The motor 2 is arranged on the placing platform 2, and the placing platform 2 is provided with a limit assembly for limiting the rotation of the motor. The rotating shaft 4 is used to drive the swing arm of the door opening device to rotate. One end of the rotating shaft 4 is connected to the output shaft 31 of the motor 3, and the other end is connected to the second connecting plate 12 through a bearing, so that the rotating shaft 4 is vertically supported between the placing table 2 and the second connecting plate 42. It should be noted that in this embodiment, the connecting member 1 and the placing table 2 are an integrally formed structure.

[0030] During actual use, the connector 1 is fixedly mounted on the vehicle body through the first connecting portion 111 and the second connecting portion 121, the motor 3 is mounted on the placement platform 2, the output shaft 31 of the motor 3 drives the connecting shaft 4, the outer periphery of the connecting shaft 4 is fixedly connected to one end of the swing arm, so as to drive the swing arm to swing, thereby realizing the opening or closing of the vehicle door. The limit assembly can improve the stability of the motor 3. Since the limit assembly can limit the overall rotation of the motor 3, the amount of fasteners required for fixing the motor 3 is reduced, and the installation area required for the fasteners is reduced, thereby reducing the installation and fastening space of the high-torque motor on the placement platform 2. When the motor 3 is subjected to additional impact force (the force generated by the reverse mis-push or mis-collision during the door opening and closing process), the motor 3 and the placement platform 2 are kept stably connected due to the limitation of the limit assembly, so as to avoid the vibration of the motor 3 causing twisting of the fasteners, and protect the torsional strength of the fasteners between the motor 3 and the placement platform 2.

[0031] See also Figures 1 to 3In a specific example provided in the present application, the limiting assembly includes a first limiting protrusion 211 and a second limiting protrusion 212, and the first limiting protrusion 211 and the second limiting protrusion 212 are arranged on the placing platform 2 and are arranged opposite to each other. Specifically, in this embodiment, the placing platform 2 includes a round table 22, and the first limiting protrusion 211 and the second limiting protrusion 212 are arranged on the round table 22. The round table 22 area between the first limiting protrusion 211 and the second limiting protrusion 212 is provided with two mounting holes 23 that penetrate the placing platform 2. The fixing bolt passes through the mounting holes 23 to fix the motor 3 on the placing platform 2. The mounting plate 32 on the motor 3 is embedded between the first limiting protrusion 211 and the second limiting protrusion 212, so that the first limiting protrusion 211 and the second limiting protrusion 212 can limit the rotation of the motor 3. It should be noted that in other embodiments, the limiting assembly may include three or four limiting protrusions, and the specific number is not specifically limited here, and can be set according to actual needs. It should be noted that the present application does not impose any specific limitation on the height of the first protrusion 211 and the second protrusion 212 above the truncated table 22 , and the heights can be set according to actual needs.

[0032] See also Figures 1 to 4 In a specific example provided in the present application, the first limiting protrusion 211 has a first limiting surface 213, the second limiting protrusion 212 has a second limiting surface, the first limiting surface 213 and the second limiting surface are both planar structures, and the first limiting surface 213 and the second limiting surface are arranged opposite to each other. In actual use, due to the planar structure of the first limiting surface 213 and the second limiting surface, the force of the mounting plate 32 of the motor 3 can be dispersed, the bearing capacity of the first limiting protrusion 211 and the second limiting protrusion 212 can be improved, and the stability of the motor 3 can be further increased. In other embodiments, a plurality of protrusions are provided on the first limiting surface 213 and / or the second limiting surface, and a limiting groove matched with the protrusion is provided on the mounting plate 32 on the motor 3, so as to further prevent the mounting plate 32 from rotating, thereby preventing the motor from rotating and improving the stability of the motor during operation. Therefore, the present application does not limit the specific structure of the first limiting protrusion 211 or the second limiting protrusion 212, and any specific structure that can limit the overall rotation of the motor 3 is within the protection scope of the present application.

[0033] The motor 3 is mounted on the placement table 2. During the actual operation, the mounting plate 32 on the motor 3 exerts a strong force on the first limiting surface 213 on the first limiting protrusion 211, which may easily damage the first limiting protrusion 211 and affect the performance of the first limiting protrusion 211 in blocking the overall rotation of the motor. Figures 1 to 5In a specific example provided in the present application, the surface of the first limiting protrusion 211 away from the motor 3 is a first arcuate surface 214, and the two side ends of the first arcuate surface 214 are respectively connected to the two side ends of the first limiting surface 213, and the surface of the second limiting protrusion 212 away from the motor 3 is a second arcuate connecting surface 215, and the two side ends of the second arcuate connecting surface 215 are respectively connected to the two side ends of the second limiting surface. In actual use, due to the arcuate structure of the first arcuate surface 214 and the second arcuate surface 215 themselves, they have strong pressure resistance. When the motor 3 applies thrust to the first limiting surface 213 and the second limiting surface, the first arcuate surface 214 can increase the strength of the first limiting protrusion 211, and the second arcuate surface 215 can increase the strength of the second limiting protrusion 212. It is worth mentioning that, in this embodiment, a first arcuate transition surface 216 is provided at the connection between the first limiting surface 213 and the adjacent first arcuate surface 214, and a second arcuate transition surface 217 is provided at the connection between the second limiting surface and the adjacent second arcuate connection surface 215. The first arcuate transition surface 216 can disperse the thrust of the mounting plate 32 on the first limiting protrusion 211, further ensuring the stability of the first limiting protrusion 211, and similarly, the second arcuate transition surface 217 is used to improve the stability of the second limiting protrusion 212, and at the same time avoid the first limiting protrusion 211 and the second limiting protrusion 212 from being damaged under the action of the mounting plate 32, thereby ensuring the stable operation of the motor and improving the safety performance of the vehicle.

It should be noted that the present application does not limit the number of reinforcing plates 112, and can be provided according to actual needs, for example, two reinforcing plates are also provided at the other end of the first connecting plate 11.

[0035] See also Figure 1 In a specific example provided in the present application, each reinforcing plate 112 is provided with an arc groove 113 for improving the connection strength of the reinforcing plate 112. The arc groove 113 can improve the strength of the reinforcing plate 112, ensure the strength between the placement table 2 and the second connecting plate 12, and improve the use stability of the motor.

It should be noted that in this embodiment, a reinforcing plate 115 is also provided on the first connecting plate 11, and the top of the reinforcing plate 115 is fixedly connected to the lower surface of the placing table 2, and the bottom of the reinforcing plate 115 is fixedly connected to the limit block 114. The reinforcing plate 115 can further enhance the strength of the limit block 114 and ensure the stability of the limit block 114 in limiting the swing arm.

[0038] See also Figures 1 to 3 In a specific example provided in the present application, the first connection portion 111 includes a first connection block 1111 disposed on the first connection plate 11. Specifically, there are two first connection blocks 1111. The first connection block 1111 is a structure extending outward from one side of the first connection plate 11.
