Description

Technical Field

[0001] The present invention relates to the technical field of motors, and in particular to an electric vehicle motor with an adjustment function. Background Art

[0002] Electric vehicles are electrically powered vehicles with strong applicability, flexibility, simple and convenient maintenance, and low price. At present, electric vehicle motors are generally installed directly on the electric vehicle to drive the drive shaft of the electric vehicle to rotate. However, the position of the electric vehicle motor cannot be adjusted, which brings inconvenience to the subsequent maintenance of the electric vehicle motor. In addition, since electric vehicles will be subject to bumps when driving, it is also necessary to maintain the stability of the motor installation.

[0003] For example, an electric vehicle motor with an adjustment function, with the announcement number CN222192055U, includes a drive shaft and a track plate mounted on the electric vehicle frame. A spline shaft is integrally formed at one end of the drive shaft, a drive box is provided on the spline shaft, and the drive box is slidably connected to the track plate. The drive box includes a protective shell slidably connected to the track plate, and a driving gear and a driven gear rotatably connected to the inner side of the protective shell. A tooth chain is provided between the driving gear and the driven gear. By providing a spline shaft at the end of the drive shaft, a slidable drive box is provided between the spline shaft and the track plate. The motor body is installed on the outside of the drive box. When the drive box moves, it does not affect the rotational drive of the spline shaft and the drive shaft. The position of the motor body can be adjusted according to needs to achieve adjustment of the motor body. However, when the motor drives the drive shaft to rotate, the motor is positioned only by the self-locking of the screw rod. When encountering bumps during subsequent driving, the friction surface between the sliding block and the screw rod will produce relative micro-movement, causing the friction surface to become smoother and smoother, thereby reducing the friction coefficient, which may cause self-locking failure and loosen the screw rod, thereby affecting the stable transmission of the motor and the drive shaft, reducing the driving stability of the motor, and having certain defects.

[0004] Therefore, an electric vehicle motor with an adjustment function is proposed to solve the above-mentioned problems. Summary of the Invention

[0052] The interior of the mounting box 5 is also fixedly connected to a vertical plate 613, the interior of the vertical plate 613 is provided with a circular groove, the screw cylinder 62 is rotatably connected to the circular groove, the outer side of the screw cylinder 62 is symmetrically fixedly connected to a mounting sleeve 614, the mounting sleeve 614 is located inside the circular groove, and an arc block 616 is slidably installed inside the mounting sleeve 614.

[0053] The mounting sleeve 614 is arranged in an array, and a second spring 615 is fixedly installed inside the mounting sleeve 614. One end of the second spring 615 is fixedly connected to the arc block 616. The side of the arc block 616 away from the mounting sleeve 614 is arranged in an arc shape.

[0054] The inner wall of the circular groove is symmetrically fixedly connected with an arc-shaped stopper 617, the outer side of the screw cylinder 62 is threadedly connected with an adjusting sleeve 618, and one side of the adjusting sleeve 618 is fixedly connected with a sliding plate 619, which is slidably installed with the mounting box 5, and the sliding plate 619 is fixedly connected to the motor box 8.

[0055] The arc-shaped blocks 617 are arranged in an array, and the arc-shaped block 616 is located between two adjacent arc-shaped blocks 617. A strip groove is provided on one side of the installation box 5 close to the motor box 8, and the sliding plate 619 is slidably connected to the strip groove.

[0056] Example 1: Figures 1-8 As shown, the motor body 9 drives the limiting rod 10 to rotate, the limiting rod 10 drives the rotating drum 11 and the main gear 12 to rotate, the main gear 12 drives the slave gear 13 to rotate, and the slave gear 13 drives the driving shaft 2 and the walking wheel 3 to rotate, completing the driving process.

[0057] When inspecting the motor body 9, the operator presses the handle portion 64, which drives the inner rod 63 to slide. The inner rod 63 drives the connecting piece 69 to compress the spring 1 612, and the connecting piece 69 slides on the guide rod 611, and the inner rod 63 drives the block 66 to move out of the disc groove 67, so that the block 66 is stuck in the slot 68. At this time, the inner rod 63 can drive the screw barrel 62 to rotate synchronously, and then rotate the handle portion 64. The inner rod 63 drives the screw barrel 62 to rotate, and the screw barrel 62 drives the mounting sleeve 614 to rotate. The mounting sleeve 614 drives the arc block 616 to rotate. The arc block 616 is squeezed by the arc block 617, which compresses the spring 2 615 and slides into the mounting sleeve 614. Then the arc block 616 is stuck between the lower two arc blocks 617, so that the screw barrel 62 can rotate normally in sections.

[0058] The sliding plate 619 slides and limits on the installation box 5, and the rotation of the screw cylinder 62 drives the adjustment sleeve 618 and the sliding plate 619 to slide, and the sliding plate 619 drives the motor box 8 to slide, and the motor box 8 drives the motor body 9 and the limit rod 10 to slide, thereby pulling the motor box 8 and the motor body 9 out for inspection, improving the convenience of inspection and the self-locking effect after adjustment.

Until the adjustment sleeve 618 rests on the limit ring 65, the handle part 64 is released, and the elastic force of the spring 1 612 drives the connecting piece 69 and the inner rod 63 to reset, and the inner rod 63 drives the block 66 to move out of the slot 68.

[0060] Then rotate the handle portion 64 through a certain arc so that the block 66 is located in the disc groove 67 and does not engage with the slot 68. When the vehicle is subsequently bumpy, the inner rod 63 can be rotated arbitrarily, and the arc-shaped block 617 cooperates to block the arc block 616, so that the screw cylinder 62 does not rotate, and thus the position of the motor box 8 and the motor body 9 does not rotate, thereby improving the stability of the motor body 9 during use, and solving the problem of relying solely on the self-locking of the screw rod to position the motor, which may cause self-locking failure when encountering bumps during subsequent driving, thereby affecting the stable transmission of the motor and the drive shaft.

[0062] The air cylinder 71 is fixedly connected to the bottom of the chassis frame 1 through a connecting rod 72. There are no less than two connecting rods 72. The piston plate 74 fits against the inner wall of the air cylinder 71. The end of the piston plate 74 away from the sliding rod 73 is fixedly connected to a spring three 75.

[0063] The curved rod 76 is located outside the air cylinder 71, the air outlet pipe 77 is connected to the air cylinder 71, a step ring groove 79 is opened on one side of the inner wall of the motor box 8, and a ring part 78 is rotatably connected inside the step ring groove 79. The axial flow fan blade 710 array is fixedly installed on the outside of the ring part 78.

[0064] The air outlet pipe 77 is directly opposite to the top axial flow fan blade 710. An air inlet valve 711 is connected to the outer side of the air cylinder 71. The axial flow fan blades 710 are arranged in an array, and there are no less than eight axial flow fan blades 710.

[0065] Example 2: Figures 9-11 As shown, while the motor box 8 and the motor body 9 are moving, the motor box 8 drives the curved rod 76 and the slide rod 73 to move, the slide rod 73 drives the piston plate 74 to move, the piston plate 74 stretches the spring three 75 and compresses the air in the air cylinder 71, and inputs the air into the motor box 8 through the air outlet pipe 77. The gas in the air outlet pipe 77 will blow the axial flow fan blades 710 to rotate, and the axial flow fan blades 710 drive the annular part 78 to rotate. The axial flow fan blades 710 assist in blowing air and dissipating heat for the motor body 9, which is convenient for subsequent maintenance operations. When the motor box 8 and the motor body 9 are reset, the air intake valve 711 is replenished with one-way air intake, so that the subsequent air blowing of the air outlet pipe 77 can be carried out stably.

[0066] Working principle: When using this device, first, Figures 1-11 As shown, the motor body 9 drives the limiting rod 10 to rotate, the limiting rod 10 drives the rotating drum 11 and the main gear 12 to rotate, the main gear 12 drives the slave gear 13 to rotate, and the slave gear 13 drives the driving shaft 2 and the walking wheel 3 to rotate, completing the driving process.

[0067] When inspecting the motor body 9, the operator presses the handle portion 64, which drives the inner rod 63 to slide, so that the block 66 is stuck in the slot 68. At this time, the inner rod 63 can drive the screw barrel 62 to rotate synchronously. Then, the handle portion 64 is turned, and the inner rod 63 drives the screw barrel 62 to rotate. The screw barrel 62 drives the mounting sleeve 614 to rotate, and the mounting sleeve 614 drives the arc block 616 to rotate. The arc block 616 is squeezed by the arc block 617, which compresses the spring 2 615 and slides into the mounting sleeve 614, so that the screw barrel 62 can be segmented. Normal rotation allows the motor box 8 and the motor body 9 to be pulled out for inspection, which improves the convenience of inspection and the self-locking effect after adjustment. While the motor box 8 and the motor body 9 are moving, the motor box 8 drives the curved rod 76 and the slide rod 73 to move, and the slide rod 73 drives the piston plate 74 to move. The piston plate 74 stretches the spring three 75 and compresses the air in the air cylinder 71, and inputs the air into the motor box 8 through the air outlet pipe 77. The gas in the air outlet pipe 77 will blow the axial flow fan blades 710 to rotate, and the axial flow fan blades 710 will assist in blowing air to dissipate heat for the motor body 9.
