Description

Technical Field

[0001] This invention belongs to the field of automotive motor technology, specifically relating to an assembly method for a base for new energy vehicles. Background Technology

[0002] New energy vehicle motors refer to the drive motors used in new energy vehicles. Their forms vary depending on the operating environment and frequency. Different types of motors also have different characteristics. New energy vehicle motors generally use permanent magnet DC motors. Based on the type of electricity they transmit, new energy vehicle motors can be divided into two main categories: brushed motors and brushless motors. Based on the mechanical structure of the motor assembly, they are generally divided into two main categories: "geared" (high motor speed, requiring gear reduction) and "gearless" (motor torque output without any reduction gear).

[0003] The motors of new energy vehicles are fixed inside the car by a base. However, the existing bases lack protection for the motors, and the road conditions in which the car is driven are varied. Bumps may cause the wires to come loose and the motor to shift, affecting normal driving. Summary of the Invention

[0004] The purpose of this invention is to solve the aforementioned technical problems existing in the prior art and to provide an assembly method for a base for new energy vehicles. The method involves assembling the base using an assembly table. First, clamping is performed, with a fixing platform on the assembly table positioning and fixing the support seat. A rotating clamping mechanism clamps and fixes the protective frame. Then, the base is installed. First, the longitudinal support rod is fixed to the support seat, and then the transverse support rod is fixed to both ends of the longitudinal support rod using L-shaped fixing seats, completing the base installation. Next, a rotating clamping mechanism controls the protective frame to rotate above the assembly table, and then the rotating clamping mechanism drives the protective frame to slide above the base, thus securing the protective frame. The protective frame is connected to the base to complete the installation of the protective frame. Then, the motor is installed in the mounting cavity formed by the protective frame and the base. This allows the protective frame to protect the motor, preventing external objects from bumping into it and improving the safety of motor use. The limiting component is installed in the mounting cavity, with the lower limiting member supporting the bottom of the motor and the upper limiting member abutting against the top of the motor, thereby fixing the motor in the mounting cavity. The limiting component is used to limit the motor in the mounting cavity, greatly improving the stability of motor installation. At the same time, the setting of the limiting component can be used for motors of various sizes, increasing the applicability of the base.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A method for assembling a base for a new energy vehicle includes the following steps: a. Equipment before assembly First, prepare all the necessary components for the base installation, clean all the components and the assembly table, and then reset the assembly table. b. Clamping and fixing 1) Positioning and fixing of the support base The top surface of the assembly platform is slidably connected to the fixed platform. An adjustment component is provided between the two fixed platforms at one end. The adjustment component is used to adjust the distance between the two fixed platforms at one end so that the fixed platform can be set with the support seats at the four corners of the bottom surface of the base. After the adjustment component adjusts the position of the fixed platform, the support seats are connected to the fixed platform and fixed by water inlet. 2) Fixing of the protective frame One end of the assembly table is slidably connected to a rotary clamping mechanism. The rotary clamping mechanism is used to clamp the protective frame and control the protective frame to rotate onto the assembly table. Then, the rotary clamping mechanism drives the protective frame to slide, so that the protective frame is installed on the base. c. Installation of support base and base First, place both ends of the longitudinal support rod in the base on the support seat, fix the bottom of the longitudinal support rod to the support seat, and then fix the transverse support rod to the longitudinal support rod through the L-shaped fixing seat to complete the installation of the base; d. Assembly of the protective frame First, a fixed slide rail is welded to the top of the base. A sliding frame is fixedly installed at the bottom of the protective frame. The rotating clamping mechanism drives the clamped protective frame to rotate onto the assembly table, so that the protective frame is on the assembly table. Then, the rotating clamping mechanism is controlled to move the protective frame to one side of the base. The sliding frame at the bottom of the protective frame slides into the slide rail at the top of the horizontal support rod, thereby connecting the protective frame to the base. Then, the rotating clamping mechanism releases the protective frame and rotates it to the initial position. e. Installation of limit components The motor is placed in the mounting cavity formed by the protective frame and the base. The limiting component includes an upper limit component and a lower limit component. The upper limit component is installed on the upper part of the protective frame, and the lower limit component is installed on the longitudinal support rod, so that the lower limit component supports the bottom of the motor and the upper limit component abuts against the top of the motor, thereby completing the assembly of the base.

[0006] Furthermore, the assembly platform includes a tabletop, fixed platforms, adjusting components, and a rotary clamping mechanism. A track is fixedly connected to the top surface of the tabletop, and the fixed platforms are slidably connected to the track. Adjusting components are connected between the two fixed platforms at one end, controlling their relative movement towards each other on the track. The rotary clamping mechanism is slidably connected to one end of the tabletop. The fixed platforms first position and fix the support base, facilitating subsequent installation of the base. The rotary clamping mechanism clamps and fixes the protective frame outside the tabletop, increasing the operating space for clamping the protective frame and facilitating its installation. The protective frame is then installed onto the base via the rotary clamping mechanism.

[0007] Furthermore, the base includes a support seat, a base, a protective frame, and a limiting component. The base and the protective frame together form an installation cavity. The base includes longitudinal and transverse support rods. The transverse support rods are fixedly connected to both ends of the longitudinal support rods via L-shaped fixing seats. The support seat is fixedly connected to both ends of the bottom surface of the longitudinal support rods. The protective frame is fixedly connected to the base. The limiting component includes an upper limiting component and a lower limiting component. The upper limiting component is connected to the protective frame, and the lower limiting component is connected to the base. Both the upper limiting component and the lower limiting component are located within the installation cavity. The upper limiting component abuts against the top of the vehicle motor, and the lower limiting component supports the bottom of the vehicle motor. The support seat provides support for the base, while the base for new energy vehicles provides a fixed installation function. The protective frame and the base together form an installation cavity, and the limiting component limits and fixes the motor within the installation cavity, thereby protecting the motor.

[0008] Furthermore, in step b, the bottom of the support base has connecting grooves at both ends, and the top surface of the fixed platform has a corresponding fixing screw. The fixing screw passes through the connecting groove, and a fixing nut is screwed into the end of the fixing screw. The fixing nut is tightened onto the support base. The bottom of the fixed platform has a sliding groove that matches the track. The support base is installed on the top surface of the fixed platform by the fixing screw and fixing nut on the top surface of the fixed platform. The sliding groove allows the support base to slide on the track.

[0009] Furthermore, the longitudinal support rod has grooves at both ends corresponding to the support base, with reinforcing plates inside the grooves. A connecting hole is located at the bottom of the groove, and a threaded connecting rod is located at the top of the support base. The threaded connecting rod passes through the connecting hole, and a connecting nut is screwed into the end of the threaded connecting rod, tightening it within the groove. The threaded connecting rod is located at the top of the support base, with its top passing through the connecting hole and positioned in the groove. The connecting nut is then screwed into the top of the threaded connecting rod and tightened within the groove, thus fixing the support base and the longitudinal support rod together.

[0010] Furthermore, the adjustment assembly includes a mounting base, a positive and negative threaded screw, a screw motor, adjusting blocks, and hinged rods. The positive and negative threaded screws are rotatably connected to the mounting base, and the screw motor is fixedly connected to one end of the mounting base. The screw motor drives the positive and negative threaded screws to rotate. Adjusting blocks are connected to both ends of the positive and negative threaded screws, and each end of the adjusting block is hinged to one end of a corresponding fixed platform. The mounting base is used to install the positive and negative threaded screws and the screw motor. The screw motor controls the rotation of the positive and negative threaded screws, causing the adjusting blocks at both ends of the positive and negative threaded screws to move towards each other along the direction of the screws. This, in turn, drives the fixed platforms at both ends of the track to move towards each other along the direction of the track via the hinged rods, thereby adjusting the distance between the two fixed platforms and thus adjusting the installation position of the support base.

[0011] Furthermore, the rotary clamping mechanism includes a sliding seat, a rotating rod, a connecting arm, a drive assembly, and a clamping assembly. One end of the table surface has a sliding groove, and the sliding seat is slidably connected in the sliding groove. The rotating rod is rotatably connected to the top of the sliding seat. The drive assembly is fixedly connected to one end of the sliding seat, and one end of the connecting arm is fixedly connected to the top of the rotating rod. The clamping assembly is located at the other end of the connecting arm and is used to clamp the protective frame. The drive assembly drives the rotating rod to rotate the connecting arm, thereby controlling the clamping assembly to rotate the protective frame onto the assembly table. The sliding seat drives the clamping assembly and the protective frame to slide along the direction of the sliding groove. The clamping assembly is used to clamp and fix the protective frame. The drive assembly controls the rotating rod to rotate the connecting arm and the clamping assembly, thereby rotating the protective frame onto the assembly table. The sliding seat is slidably connected in the sliding groove, thus driving the rotating rod, clamping assembly, and drive assembly to slide along the direction of the sliding groove, allowing the sliding frame in the protective frame to slide into the slide rail on the base, completing the installation of the base and the protective frame.

[0012] Furthermore, the drive assembly includes a bracket, a drive motor, a transmission belt, a driving pulley, and a driven pulley. The bracket is fixedly connected to the sliding seat, and the drive motor is fixedly connected to the bracket. The output end of the drive motor is connected to the driving pulley, and the bottom of the rotating rod is connected to the driven pulley. A transmission belt connects the driving pulley and the driven pulley. The drive motor controls the rotation of the driving pulley, which in turn drives the driven pulley to rotate via the transmission belt, thereby controlling the rotation of the rotating rod. The drive motor controls the rotation of the driving pulley, which in turn drives the driven pulley to rotate, thus rotating the rotating rod and enabling the clamping assembly to rotate the protective frame onto the assembly table.

[0013] Furthermore, the clamping assembly includes a lifting cylinder, a pushing cylinder, a clamping frame, an adjusting frame, and a clamping part. The lifting cylinder is fixedly connected to the top of the other end of the connecting arm. The output end of the lifting cylinder passes through the connecting arm and is fixedly connected to the top of the clamping frame. Both ends of the clamping frame are fixedly connected to pushing cylinders. The output ends of the pushing cylinders pass through the clamping frame and are fixedly connected to the adjusting frame. The end of the adjusting frame near the center of the clamping frame is connected to the clamping part through a telescopic damping rod. A buffer spring is sleeved on the outer side of the telescopic damping rod. The clamping part clamps the two sides of the protective frame. The inner wall of the clamping frame is provided with a guide rail. The top of the adjusting frame is provided with a guide block corresponding to the guide rail. The guide block is slidably connected to the guide rail. The lifting cylinder is used to control the lifting and lowering of the clamping frame. The push cylinder controls the adjusting frame to drive the clamping part to clamp the two sides of the top of the protective frame, so that the protective frame is fixedly connected to the clamping frame. The guide rail and guide block play a guiding role in the movement of the adjusting frame. During the clamping process, the cooperation of the buffer spring and the telescopic damping rod plays a buffering role, which plays a protective role in clamping the protective frame.

[0014] Furthermore, both the upper and lower limit components include an adjusting plate, a threaded column, and a limiting block. The threaded column is fixedly connected to the protective frame and the longitudinal support rod, respectively. The adjusting plate and the limiting block are fixedly connected. The adjusting plate has an adjusting hole through which the threaded column passes. A fastening nut is screwed into the end of the threaded column and tightened onto the adjusting plate. The limiting block has an arc-shaped limiting groove corresponding to the automotive motor. The limiting block abuts against the upper and lower ends of the automotive motor through the arc-shaped limiting groove. First, the motor is placed into the mounting cavity, and then the upper and lower limit components are installed. The threaded column passes through the adjusting hole, driving the adjusting plate to move the limiting block, so that the arc-shaped limiting groove abuts against the motor. Then, the fastening nut is tightened onto the adjusting plate for fixation, thereby fixing the motor in the mounting cavity.

[0015] The present invention, by adopting the above-described technical solution, has the following beneficial effects: This invention assembles the base using an assembly table. First, clamping is performed; a fixed platform on the assembly table positions and fixes the support seat, and a rotating clamping mechanism clamps and fixes the protective frame. Then, the base is installed. First, the longitudinal support rod is fixed to the support seat, and then the transverse support rod is fixed to both ends of the longitudinal support rod using L-shaped fixing seats, completing the base installation. Next, a rotating clamping mechanism controls the protective frame to rotate above the assembly table, and then the rotating clamping mechanism drives the protective frame to slide above the base, connecting the protective frame to the base, completing the installation of the protective frame. The motor is installed within the mounting cavity formed by the protective frame and the base. The protective frame protects the motor, preventing it from being bumped or struck by external objects, thus improving the safety of motor use. The limiting component is installed in the mounting cavity, with the lower limiting member supporting the bottom of the motor and the upper limiting member abutting against the top of the motor, thereby fixing the motor in place within the mounting cavity. The limiting component is used to limit the motor within the mounting cavity, greatly improving the stability of motor installation. At the same time, the setting of the limiting component can be used for motors of various sizes, increasing the applicability of the base.

[0016] In step b of this invention, the bottom of the support base has connecting grooves at both ends, and the top surface of the fixed platform has a corresponding fixing screw. The fixing screw passes through the connecting groove, and a fixing nut is screwed into the end of the fixing screw. The fixing nut is tightened onto the support base. The bottom of the fixed platform has a sliding groove that matches the track. The support base is installed on the top surface of the fixed platform by the fixing screw and fixing nut on the top surface of the fixed platform. The sliding groove allows the support base to slide on the track. The two ends of the longitudinal support rod have grooves corresponding to the support base. A reinforcing plate is provided in the groove, and a connecting hole is provided at the bottom of the groove. The top of the support base has a threaded connecting rod that passes through the connecting hole, and a connecting nut is screwed into the end of the threaded connecting rod. The connecting nut is tightened into the groove. The threaded connecting rod is located at the top of the support base, and the top of the threaded connecting rod passes through the connecting hole and is located in the groove. The connecting nut is then screwed into the top of the threaded connecting rod and tightened into the groove, thereby fixing the support base and the longitudinal support rod together.

[0017] The rotary clamping mechanism of this invention includes a sliding seat, a rotating rod, a connecting arm, a drive assembly, and a clamping assembly. A sliding groove is provided at one end of the platform, and the sliding seat is slidably connected in the sliding groove. The rotating rod is rotatably connected to the top of the sliding seat. The drive assembly is fixedly connected to one end of the sliding seat, and one end of the connecting arm is fixedly connected to the top of the rotating rod. The clamping assembly is located at the other end of the connecting arm and is used to clamp the protective frame.

The sliding seat drives the clamping assembly and the protective frame to slide along the direction of the sliding groove. The clamping assembly is used to clamp and fix the protective frame. The drive assembly controls the rotating rod to rotate the connecting arm and the clamping assembly, thereby rotating the protective frame onto the assembly platform. The sliding seat is slidably connected in the sliding groove, thereby driving the rotating rod, clamping assembly, and drive assembly to slide along the direction of the sliding groove, allowing the sliding frame in the protective frame to slide into the slide rail on the base, completing the installation of the base and the protective frame.

Detailed Implementation

[0020] like Figures 1 to 9 The figure shows an assembly method for a base for a new energy vehicle according to the present invention, which includes the following steps: a. Equipment before assembly First, prepare all the necessary components for the base installation, clean all the components and assembly table 1, and then reset assembly table 1. b. Clamping and fixing 1) Positioning and fixing of support base 7 The top surface of the assembly platform 1 is slidably connected to the fixed platform 3. An adjustment component 4 is provided between the two fixed platforms 3 at one end. The adjustment component 4 is used to adjust the distance between the two fixed platforms 3 at one end so that the fixed platform 3 can be set to the support seat 7 at the four corners of the bottom surface of the base. After the adjustment component 4 adjusts the position of the fixed platform 3, the support seat 7 is connected to the fixed platform 3 and fixed by water inlet. 2) Fixing of protective frame 9 One end of the assembly table 1 is slidably connected to the rotary clamping mechanism 5. The rotary clamping mechanism 5 is used to clamp the protective frame 9 and control the protective frame 9 to rotate onto the assembly table 1. Then, the rotary clamping mechanism 5 drives the protective frame 9 to slide, so that the protective frame 9 is installed on the base 8. c. Installation of support base 7 and base 8 First, place both ends of the longitudinal support rod 12 in the base 8 on the support seat 7, fix the bottom of the longitudinal support rod 12 to the support seat 7, and then fix the transverse support rod 13 to the longitudinal support rod 12 through the L-shaped fixing seat 14 to complete the installation of the base 8. d. Assembly of protective frame 9 First, a fixed slide rail 57 is welded to the top of the base 8. A sliding frame is fixedly installed at the bottom of the protective frame 9. The rotating clamping mechanism 5 drives the clamped protective frame 9 to rotate onto the assembly table 1, so that the protective frame 9 is located on the assembly table 1. Then, the rotating clamping mechanism 5 is controlled to move the protective frame 9 to one side of the base 8. The sliding frame at the bottom of the protective frame 9 slides into the slide rail 57 at the top of the transverse support rod 13, thereby connecting the protective frame 9 to the base 8. Then, the rotating clamping mechanism 5 releases the protective frame 9 and rotates it to the initial position. e. Installation of limit component 10 The motor is placed in the mounting cavity 11 formed by the protective frame 9 and the base 8. The limiting component 10 includes an upper limiting component 15 and a lower limiting component 16.

Adjusting assemblies 4 are connected between the two fixed platforms 3 at one end, controlling their relative movement towards each other on the track 6. The rotary clamping mechanism 5 is slidably connected to one end of the tabletop 2. The fixed platform 3 first positions and fixes the support base 7, facilitating the subsequent installation of the base 8. The rotary clamping mechanism 5 clamps and fixes the protective frame 9 outside the tabletop 2, increasing the operating space for clamping the protective frame 9 and facilitating its installation. The protective frame 9 is then installed onto the base 8 via the rotary clamping mechanism 5.

[0022] The base includes a support seat 7, a base 8, a protective frame 9, and a limiting component 10. The base 8 and the protective frame 9 together form an installation cavity 11. The base 8 includes a longitudinal support rod 12 and a transverse support rod 13. The transverse support rod 13 is fixedly connected to both ends of the longitudinal support rod 12 by an L-shaped fixing seat 14. The support seat 7 is fixedly connected to both ends of the bottom surface of the longitudinal support rod 12. The protective frame 9 is fixedly connected to the base 8.

[0025] The adjustment assembly 4 includes a mounting base 26, a threaded rod 27, a screw motor 28, adjusting blocks 29, and a hinge rod 30. The threaded rod 27 is rotatably connected to the mounting base 26, and the screw motor 28 is fixedly connected to one end of the mounting base 26. The screw motor 28 drives the threaded rod 27 to rotate. Adjusting blocks 29 are connected to both ends of the threaded rod 27, and hinge rods 30 are hinged to the corresponding ends of the two fixed platforms 3 at their respective ends. The mounting base 26 is used to mount the threaded rod 27 and the screw motor 28. The screw motor 28 controls the rotation of the threaded rod 27, thereby causing the adjusting blocks 29 located at both ends of the threaded rod 27 to move towards each other along the direction of the threaded rod 27. This, in turn, drives the fixed platforms 3 located at both ends of the track 6 to move towards each other along the direction of the track 6 via the hinge rod 30, thereby adjusting the distance between the two fixed platforms 3 and thus adjusting the installation position of the support base 7.

[0026] The rotary clamping mechanism 5 includes a sliding seat 31, a rotating rod 32, a connecting arm 33, a drive assembly 34, and a clamping assembly 35.

The clamping assembly 35 is used to clamp the protective frame 9. The drive assembly 34 drives the rotating rod 32 to rotate the connecting arm 33, thereby controlling the clamping assembly 35 to rotate the protective frame 9 onto the assembly table 1. The sliding seat 31 drives the clamping assembly 35 and the protective frame 9 to slide along the direction of the sliding groove 36. The clamping assembly 35 is used to clamp and fix the protective frame 9. The drive assembly 34 is used to control the rotating rod 32 to drive the connecting arm 33 and the clamping assembly 35 to rotate, thereby driving the protective frame 9 to rotate onto the assembly table 1. The sliding seat 31 is slidably connected in the sliding groove 36, thereby driving the rotating rod 32, the clamping assembly 35 and the drive assembly 34 to slide along the direction of the sliding groove 36, so that the sliding frame in the protective frame 9 slides into the slide rail 57 on the base 8, completing the installation of the base 8 and the protective frame 9.

[0027] The drive assembly 34 includes a bracket 37, a drive motor 38, a transmission belt 39, a drive pulley 40, and a driven pulley 41. The bracket 37 is fixedly connected to the sliding seat 31. The drive motor 38 is fixedly connected to the bracket 37. The output end of the drive motor 38 is connected to the drive pulley 40. The bottom of the rotating rod 32 is connected to the driven pulley 41. The transmission belt 39 connects the drive pulley 40 and the driven pulley 41. The drive motor 38 controls the rotation of the drive pulley 40, which in turn drives the driven pulley 41 to rotate via the transmission belt 39, thereby controlling the rotation of the rotating rod 32. The drive motor 38 controls the rotation of the drive pulley 40, which in turn drives the driven pulley 41 to rotate via the transmission belt 39, thus driving the rotating rod 32 to rotate. This allows the clamping assembly 35 to rotate the protective frame 9 onto the assembly table 1.

[0028] The clamping assembly 35 includes a lifting cylinder 42, a pushing cylinder 43, a clamping frame 44, an adjusting frame 45, and a clamping part 46.

The output end of the lifting cylinder 42 passes through the connecting arm 33 and is fixedly connected to the top of the clamping frame 44. Both ends of the clamping frame 44 are fixedly connected to the pushing cylinder 43. The output end of the pushing cylinder 43 passes through the clamping frame 44 and is fixedly connected to the adjusting frame 45. One end of the adjusting frame 45 near the center of the clamping frame 44 is connected to the clamping part 46 through a telescopic damping rod 47. A buffer spring 48 is sleeved on the outer side of the telescopic damping rod 47. The clamping part 46 clamps the two sides of the protective frame 9. The inner wall of the clamping frame 44 is provided with a guide rail 49. The top of the adjusting frame 45 is provided with a guide block 50 corresponding to the guide rail 49. The guide block 50 is slidably connected to the guide rail 49. The lifting cylinder 42 is used to control the lifting and lowering of the clamping frame 44. The push cylinder 43 controls the adjusting frame 45 to drive the clamping part 46 to clamp the two sides of the top of the protective frame 9, so that the protective frame 9 is fixedly connected to the clamping frame 44. The guide rail 49 and the guide block 50 play a guiding role in the movement of the adjusting frame 45. During the clamping process, the clamping part 46, the buffer spring 48 and the telescopic damping rod 47 play a buffering role, which plays a protective role in the clamping of the protective frame 9.

[0029] Both the upper limit component 15 and the lower limit component 16 include an adjusting plate 51, a threaded column 52, and a limiting block 53. The threaded column 52 is fixedly connected to the protective frame 9 and the longitudinal support rod 12, respectively. The adjusting plate 51 and the limiting block 53 are fixedly connected. The adjusting plate 51 is provided with an adjusting hole 54. The threaded column 52 passes through the adjusting hole 54. A fastening nut 55 is screwed into the end of the threaded column 52. The fastening nut 55 is tightened on the adjusting plate 51. The limiting block 53 is provided with an arc-shaped limiting groove 56 corresponding to the car motor 58. The limiting block 53 abuts against the upper and lower ends of the car motor 58 through the arc-shaped limiting groove 56. First, place the motor into the mounting cavity 11, then install the upper limit member 15 and the lower limit member 16. The threaded column 52 passes through the adjustment hole 54, drives the adjustment plate 51 to drive the limit block 53, so that the arc-shaped limit groove 56 abuts against the motor. Then tighten the fastening nut 55 on the adjustment plate 51 to fix it, thereby fixing the motor in the mounting cavity 11.

[0030] This invention assembles the base using an assembly table 1. First, clamping is performed; the fixing table 3 on the assembly table 1 positions and fixes the support base 7, and the rotating clamping mechanism 5 clamps and fixes the protective frame 9. Then, the base 8 is installed. First, the longitudinal support rod 12 is fixed to the support base 7, and then the transverse support rod 13 is fixed to both ends of the longitudinal support rod 12 via L-shaped fixing seats 14, completing the installation of the base 8. Next, the rotating clamping mechanism controls the protective frame 9 to rotate above the assembly table 1, and then the rotating clamping mechanism drives the protective frame 9 to slide above the base 8, connecting the protective frame 9 to the base 8, completing the installation of the protective frame 9. The motor is installed in the mounting cavity 11 formed by the protective frame 9 and the base 8, so that the protective frame 9 can protect the motor and prevent foreign objects from hitting the motor, thus improving the safety of the motor. The limiting component 10 is installed in the mounting cavity 11, so that the lower limiting member 16 of the limiting component 10 supports the bottom of the motor and the upper limiting member 15 abuts against the top of the motor, thereby fixing the motor in the mounting cavity 11. The limiting component 10 is used to limit the motor in the mounting cavity 11, which greatly improves the stability of the motor installation. At the same time, the setting of the limiting component 10 can be used for motors of various sizes, increasing the applicability of the base.
