Description

Technical Field

[0001] The invention belongs to the technical field of motors, and provides a motor whose rotor shaft can translate left and right, and in particular relates to a double-drive regulating motor. Background Art

[0002] Many actuators do not move in one direction during their operation, which requires two or more motors to drive. For example, the rearview mirror is an important tool for the driver to observe the situation behind and to the side of the vehicle. Reasonable adjustment of the rearview mirror angle can effectively reduce the blind spot of vision and allow the driver to timely understand the surrounding traffic conditions, such as the driving position and speed of the rear vehicle and whether there are vehicles preparing to overtake or merge, thereby reducing the risk of traffic accidents. For example, when changing lanes or turning, the correct rearview mirror angle can help the driver confirm the safety of the rear and avoid collisions.

[0003] The rearview mirror needs to be adjusted inward and outward in the horizontal direction so that the driver can see what is close to and away from the body of the car, and it needs to be adjusted upward and downward in the vertical direction so that the driver can see what is far away from the ground and what is close to the ground. Because the rearview mirror needs to be adjusted in two directions, the traditional adjustment requires two motors to drive it, and the space inside the rearview mirror is small, which brings difficulties to the layout of the motor. A new type of motor is needed to solve the above problems. Summary of the invention

[0004] The present invention proposes a double transmission regulating motor. The purpose of the present invention is to provide a motor which can realize transmission in two directions by using one rotor shaft.

[0005] The technical solution of the present invention is as follows: a double-drive regulating motor, comprising a shell, a stator coil and a rotor shaft are arranged in the shell, two ends of the rotor shaft pass through the shell, a translation coil is arranged in the shell near the two ends of the rotor shaft, the winding directions of the two translation coils are the same, magnet rings are arranged at the two ends of the rotor shaft corresponding to the translation coils, the two magnet rings are arranged in opposite directions so that the magnetic poles of the two magnet rings are in opposite directions, the N pole is near the inside, and the S pole is near the outside, the rotor shaft can be connected to the first transmission mechanism by translating to the left, and the rotor shaft can be connected to the second transmission mechanism by translating to the right.

[0006] As a preferred solution of the present invention, further, a bearing is provided between the rotor shaft and the housing to reduce friction when the rotor shaft rotates.

[0007] As a preferred solution of the present invention, further, the stator coil and the translation coil are both wrapped by insulating material to ensure electrical safety.

[0008] As a preferred solution of the present invention, further, the magnet ring is fixed on the rotor shaft by bonding.

[0009] The beneficial effects of the present invention are:

[0010] The structure of the present invention is relatively simple and compact, and can be more conveniently installed in a limited space. The working principle of the translation coil enables the through-type electromagnet push-pull motor to generate electromagnetic force in a short time, thereby realizing the push-pull action on the rotor shaft, thereby quickly switching the first transmission mechanism and the second transmission mechanism to realize the double transmission of the two transmission mechanisms.

[0011] Compared with some traditional motor drive methods, the through-type electromagnet push-pull motor has fewer moving parts, which enables one motor to be controlled and adjusted in two directions. It has high reliability and stability, can maintain good working performance during long-term use, and reduces maintenance costs and usage risks. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Example 1

[0018] like Figure 1 , 2 As shown, this embodiment proposes a double transmission regulating motor, including a housing 1;

[0019] The stator coil 2 is arranged in the housing 1. The stator coil 2 can control the rotor shaft 5 to rotate forward or reversely by energizing it in the forward direction or reverse direction.

[0020] The rotor shaft 5 passes through the housing 1, and its left end can be connected to the first transmission mechanism, and its right end can be connected to the second transmission mechanism;

[0021] The translation coil 3 is arranged in the housing 1 near the two ends of the rotor shaft 5;

[0022] The magnet ring 4 is fixedly arranged at both ends of the rotor shaft 5 corresponding to the translation coil 3, wherein when the translation coil 3 is not energized, no attraction is generated on the magnet ring 4, and the rotor shaft 5 does not translate; when the translation coil 3 is energized in the forward direction, an attraction to the left is generated on the magnet ring 4, driving the rotor shaft 5 to translate to the left and connecting to the first transmission mechanism; when the translation coil 3 is energized in the reverse direction, an attraction to the right is generated on the magnet ring 4, driving the rotor shaft 5 to translate to the right and connecting to the second transmission mechanism.

[0023] Example 2

[0024] like Figure 1 , 2 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a bearing is provided between the rotor shaft 5 and the housing 1 to reduce friction when the rotor shaft 5 rotates.

[0025] The stator coil 2 and the translation coil 3 are both wrapped by insulating materials to ensure electrical safety.

[0026] The magnet ring 4 is fixed on the rotor shaft 5 by bonding.

[0027] The double transmission adjustment motor can be used as a rearview mirror adjustment motor for automobiles. When the driver needs to adjust the horizontal angle of the rearview mirror, he or she turns the switch to control the translation coil 3 to be energized in the forward direction.

[0028] When the translation coil 3 is energized in the forward direction, a magnetic force in a specific direction will be generated around it. Since the magnet rings 4 fixed at both ends of the rotor shaft 5 are magnetic, according to the electromagnetic principle that like charges repel and opposite charges attract, the magnetic force generated by the translation coil 3 will produce an attractive force to the left on the magnet ring 4.

[0029] This attraction will cause the rotor shaft 5 to move smoothly to the left along its axial direction. During the movement, the rotor shaft 5 gradually approaches and finally connects with the horizontal rotation mechanism of the rearview mirror, ensuring that during the subsequent rotation adjustment process, the rotation of the rotor shaft 5 can be accurately transmitted to the horizontal rotation mechanism of the rearview mirror, thereby realizing the adjustment of the horizontal angle of the rearview mirror.

[0030] When the rotor shaft 5 is successfully connected to the rearview mirror horizontal rotation mechanism, the driver turns the switch to control the stator coil 2 to be energized in the forward or reverse direction, driving the rotor shaft 5 to rotate forward or reversely, driving the rearview mirror horizontal rotation mechanism, and causing the rearview mirror to flip up or down.

[0031] When the driver wants to adjust the angle of the rearview mirror in the vertical direction, he turns the switch to control the translation coil 3 to be energized in the reverse direction.

[0032] When the translation coil 3 is energized in the reverse direction, the direction of the magnetic force generated around it is opposite to that when it is energized in the forward direction. According to the electromagnetic principle, the magnetic force generated by the translation coil 3 at this time will generate a rightward attractive force on the magnet rings 4 at both ends of the rotor shaft 5.

[0033] The rightward attraction forces the rotor shaft 5 to move rightward along the axial direction. During the movement, the rotor shaft 5 gradually and precisely docks and connects with the vertical rotation mechanism of the rearview mirror. This connection method ensures that the rotation of the rotor shaft 5 can be effectively transmitted to the vertical rotation mechanism of the rearview mirror, preparing for subsequent vertical rotation adjustment.

[0034] When the rotor shaft 5 is successfully connected to the rearview mirror vertical rotation mechanism, the driver flips the switch to control the stator coil 2 to be energized in the forward or reverse direction, driving the rotor shaft 5 to rotate forward or reversely, driving the rearview mirror vertical rotation mechanism, and causing the rearview mirror to flip inward or outward.

[0035] Workflow:

[0036] S1. Initial state

[0037] The translation coil 3 is not energized, and at this time the translation coil 3 does not generate attraction to the magnet ring 4, and the rotor shaft 5 is in the middle position and is not connected to the horizontal rotation mechanism or the vertical rotation mechanism of the rearview mirror.

[0038] S2. Horizontal adjustment process

[0039] Connect the horizontal rotation mechanism:

[0040] When the angle of the rearview mirror needs to be adjusted in the horizontal direction, the switch is turned to control the translation coil 3 to be energized in the forward direction.

[0041] When the translation coil 3 is energized in the forward direction, it generates a leftward attractive force on the magnet rings 4 at both ends of the rotor shaft 5 .

[0042] Under the action of this attractive force, the rotor shaft 5 translates to the left until it is connected to the horizontal rotation mechanism of the rearview mirror.

[0043] Horizontal rotation adjustment:

[0044] After the connection is completed, the switch is turned to control the stator coil 2 to be energized in the forward direction. According to the principle of electromagnetic induction, the stator coil 2 generates a magnetic field to drive the rotor shaft 5 to rotate forward.

[0045] The positive rotation of the rotor shaft 5 drives the horizontal rotation mechanism of the rearview mirror to move, so that the rearview mirror is rotated upward in the horizontal direction for adjustment.

[0046] When the rearview mirror needs to be adjusted to rotate downward in the horizontal direction, the switch is turned to control the stator coil 2 to be energized in the reverse direction, and the rotor shaft 5 is reversed, thereby driving the rearview mirror to rotate downward in the horizontal direction.

[0047] S3, vertical adjustment process

[0048] Connect the vertical rotation mechanism:

[0049] When the rearview mirror needs to be adjusted in the vertical direction, the switch is turned to control the translation coil 3 to be energized in the reverse direction.

[0050] When the translation coil 3 is energized in the reverse direction, it generates a rightward attraction force on the magnet rings 4 at both ends of the rotor shaft 5 .

[0051] The rotor shaft 5 is translated to the right under the action of the attraction force until it is connected with the vertical rotation mechanism of the rearview mirror.

[0052] Vertical rotation adjustment:

[0053] After the connection is completed, the switch is turned to control the stator coil 2 to be energized in the forward direction, and the stator coil 2 generates a magnetic field to drive the rotor shaft 5 to rotate forward.

[0054] The positive rotation of the rotor shaft 5 drives the vertical rotation mechanism of the rearview mirror to move, so that the rearview mirror is rotated inward in the vertical direction for adjustment.

[0055] When the rearview mirror needs to be adjusted to rotate outward in the vertical direction, the switch is turned to control the stator coil 2 to be energized in the reverse direction, and the rotor shaft 5 is reversed, thereby driving the rearview mirror to rotate outward in the vertical direction.

[0056] S4, end adjustment

[0057] When the rearview mirror is adjusted to the desired angle, the switch is turned to stop the power supply to the translation coil 3 and the stator coil 2, the rotor shaft 5 stops moving and rotating, and the rearview mirror remains in the adjusted position.

[0058] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
