TECHNICAL FIELD
[0001] The application belongs to the technical field of electric machines, and provides a motor with a rotatable shaft capable of left-right translation, in particular to a double transmission adjusting motor. BACKGROUND
[0002] Many actuators are not moved in one direction during operation, which requires two or more motors for transmission. For example, the rearview mirror of a vehicle is an important tool for the driver to observe the rear and side of the vehicle. Reasonable adjustment of the rearview mirror angle can effectively reduce the blind area of view, so that the driver can timely understand the surrounding traffic conditions, such as the driving position, speed and whether there are vehicles preparing to overtake or parallel, etc. of the rear vehicle, 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 behind and avoid collision.
[0003] The adjustment of the rearview mirror requires horizontal inward and outward adjustment so that the driver can see the situation close to and away from the vehicle body, and vertical upward and downward adjustment so that the driver can see the situation away from and close to the ground. Because the rearview mirror needs to be adjusted in two directions, the traditional adjustment requires two motors for transmission, and the space inside the rearview mirror is small, which brings difficulty to the layout of the motor. A new type of motor is needed to solve the above problems. SUMMARY

[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are involved in the protection scope of the present application.
[0017] Embodiment 1
[0018] As shown in Figure 1 , 2 the present embodiment proposes a double transmission adjusting motor, which comprises a housing 1;
[0019] a stator coil 2 arranged in the housing 1, the stator coil 2 being capable of controlling the rotor shaft 5 to rotate forward or reverse by forward or reverse energization;
[0020] The rotor shaft 5 extends out of the outer casing 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] Translation coil 3 is located inside housing 1 near both ends of rotor shaft 5;
[0022] The magnet ring 4 is fixedly installed at both ends of the rotor shaft 5 corresponding to the translation coil 3. When the translation coil 3 is not energized, it does not generate an attraction force on the magnet ring 4, and the rotor shaft 5 does not translate. When the translation coil 3 is energized in the forward direction, it generates a leftward attraction force on the magnet ring 4, causing the rotor shaft 5 to translate to the left and connect with the first transmission mechanism. When the translation coil 3 is energized in the reverse direction, it generates a rightward attraction force on the magnet ring 4, causing the rotor shaft 5 to translate to the right and connect with the second transmission mechanism.
[0023] Example 2
[0024] like Figure 1 , 2 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that a bearing be provided between the rotor shaft 5 and the housing 1 to reduce friction when the rotor shaft 5 rotates.
[0025] Both stator coil 2 and translation coil 3 are wrapped with insulating material to ensure electrical safety.
[0026] The magnet ring 4 is fixed to the rotor shaft 5 by adhesive bonding.
[0027] The dual-drive adjustment motor can be used as a car rearview mirror adjustment motor. When the driver needs to adjust the horizontal angle of the rearview mirror, he flips the switch to control the translation coil 3 to be energized in the positive direction.
[0028] When the translation coil 3 is energized in the positive direction, it will generate a magnetic force in a specific direction 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 poles repel and unlike poles attract, the magnetic force generated by the translation coil 3 will exert an attractive force to the left on the magnet rings 4.
[0029] This attraction causes the rotor shaft 5 to move smoothly to the left along its axis. During the movement, the rotor shaft 5 gradually approaches and eventually connects with the rearview mirror horizontal rotation mechanism, ensuring that the rotation of the rotor shaft 5 can be accurately transmitted to the rearview mirror horizontal rotation mechanism during subsequent rotation adjustment, thereby realizing the adjustment of the horizontal angle of the rearview mirror.
[0030] After the rotor shaft 5 is successfully connected to the horizontal rotation mechanism of the rearview mirror, the driver turns on the switch to control the stator coil 2 to be energized in the forward or reverse direction, thereby driving the rotor shaft 5 to rotate in the forward or reverse direction, which in turn drives the horizontal rotation mechanism of the rearview mirror to flip the rearview mirror up or down.
[0031] When the driver wants to adjust the angle of the rearview mirror in the vertical direction, the switch is actuated to control the reverse energization of the translation coil 3.
[0032] After the translation coil 3 is reversely energized, the direction of the magnetic force generated around it is opposite to that when it is forwardly energized. 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 attractive force causes the rotor shaft 5 to move rightward along the axial direction, and the rotor shaft 5 gradually and accurately connects with the rearview mirror vertical direction rotation mechanism during the movement. This connection ensures that the rotation of the rotor shaft 5 can be effectively transmitted to the rearview mirror vertical direction rotation mechanism, preparing for subsequent vertical direction rotation adjustment.
[0034] When the rotor shaft 5 is successfully connected with the rearview mirror vertical direction rotation mechanism, the driver actuates the switch to control the forward or reverse energization of the stator coil 2, driving the rotor shaft 5 to rotate forward or reversely, and driving the rearview mirror vertical direction rotation mechanism to make the rearview mirror turn 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 an attractive force on the magnet rings 4, and the rotor shaft 5 is in the middle position and is not connected with the rearview mirror horizontal direction rotation mechanism or the vertical direction rotation mechanism.
[0038] S2, horizontal direction adjustment process
[0039] Connect the horizontal direction rotation mechanism:
[0040] When the angle of the rearview mirror in the horizontal direction needs to be adjusted, the switch is actuated to control the forward energization of the translation coil 3.
[0041] After the translation coil 3 is forwardly energized, a leftward attractive force is generated on the magnet rings 4 at both ends of the rotor shaft 5.
[0042] Under the action of the attractive force, the rotor shaft 5 translates leftward until it is connected with the rearview mirror horizontal direction rotation mechanism.
[0043] Horizontal direction rotation adjustment:
[0044] After the connection is completed, the switch is actuated to control the forward energization of the stator coil 2. According to the electromagnetic induction principle, the stator coil 2 generates a magnetic field to drive the rotor shaft 5 to rotate forward.
[0045] The forward rotation of the rotor shaft 5 drives the rearview mirror horizontal direction rotation mechanism to move, making the rearview mirror rotate upward in the horizontal direction for adjustment.
[0046] When the rearview mirror needs to be adjusted in the horizontal direction, the switch is toggled to control the stator coil 2 to reverse the current, the rotor shaft 5 is reversed, and the rearview mirror is further rotated in the horizontal direction.
[0047] S3, vertical direction adjustment process
[0048] Connect the vertical direction rotating mechanism:
[0049] When the rearview mirror needs to be adjusted in the vertical direction, the switch is toggled to control the translation coil 3 to reverse the current.
[0050] After the translation coil 3 is reversed, the magnet ring 4 at both ends of the rotor shaft 5 is attracted to the right.
[0051] The rotor shaft 5 is translated to the right under the action of the attractive force until it is connected with the vertical direction rotating mechanism of the rearview mirror.
[0052] Vertical direction rotation adjustment:
[0053] After the connection is completed, the switch is toggled to control the stator coil 2 to forward the current, and the stator coil 2 generates a magnetic field to drive the rotor shaft 5 to rotate forward.
[0054] The rotor shaft 5 rotates forward to drive the vertical direction rotating mechanism of the rearview mirror to move, so that the rearview mirror is adjusted in the vertical direction.
[0055] When the rearview mirror needs to be adjusted in the vertical direction, the switch is toggled to control the stator coil 2 to reverse the current, the rotor shaft 5 is reversed, and the rearview mirror is further rotated in the vertical direction.
[0056] S4, end adjustment
[0057] When the rearview mirror is adjusted to the required angle, the switch is toggled 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 is only the preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
