Description

Technical Field

[0001] This utility model relates to the field of imaging equipment technology, specifically to a side-guided optical platform, a camera module, and an electronic device. Background Technology

[0002] In imaging devices such as cameras and mobile phones, optical image stabilization (OIS) is a core technology that uses dynamic adjustments of optical elements to counteract camera shake and ensure clear images. For example, lens-shift OIS, commonly found in cameras and mobile phones, uses a motor to drive one or more lens elements in the camera module to move in the opposite direction of the shake, correcting the angle of light incidence. Specifically, when taking a picture, if hand shake causes the camera module to shift upwards, the lens automatically moves downwards, ensuring that the imaging light is always focused on the center of the sensor.

[0003] Chinese patent document CN105589278B discloses a camera module employing a three-tiered frame design. The first frame is fixed within a housing and can move along the optical axis (Z-axis) for autofocus. The second frame is housed within the first frame and supported by a first ball bearing; it can only move along a first direction perpendicular to the optical axis (X-axis). The third frame, integrated with a lens barrel, is supported on the second frame by a second ball bearing and can only move relative to the second frame along a second direction (Y-axis, perpendicular to both the optical and X-axis).

[0004] The above technical solution enables bidirectional image stabilization. Specifically, a first magnet is mounted on the third frame, and a first coil is fixed to the housing, arranged opposite each other along the X-axis. Upon energization, the first magnet and the first coil generate electromagnetic interaction, driving the third and second frames to move along the X-axis, compensating for hand tremors in the X-axis direction. A second magnet is mounted on the third frame, and a second coil is fixed to the housing, arranged opposite each other along the Y-axis. Upon energization, the second magnet and the second coil generate electromagnetic interaction, driving the third frame to move along the Y-axis, compensating for hand tremors in the Y-axis direction.

[0005] However, by adopting the above technical solution, since the first frame, the second frame and the third frame are arranged sequentially along the optical axis (Z-axis), the height in the Z-axis direction is relatively large, which is not conducive to the thinning design of the camera module. Utility Model Content

[0006] In view of this, the present invention provides a side-guided optical platform, a camera module, and an electronic device to solve the problem of the large height of existing optical platforms along the optical axis.

[0007] This utility model provides a side-guided optical platform, comprising:

[0008] The base has a first contact part;

[0009] A movable seat is slidably disposed on the base, and the movable seat has a second abutment portion;

[0010] A guide member is disposed on the side of the base and the movable seat. The guide member has a first guide surface that mates with the first abutting part and a second guide surface that mates with the second abutting part. The first guide surface and the second guide surface are arranged at an angle.

[0011] A limiting mechanism acts between the base and the guide member to ensure that the first abutting part and the first guide surface are always in contact and engaged.

[0012] The movable base has a first magnet and / or a second magnet, and the base has a magnetic material. The first magnet and / or the second magnet are used to attract the base so that the base and the movable base are always in contact and fit together.

[0013] The guide has a magnetic material, and the first magnet and / or the second magnet can attract the guide so that the second abutting part and the second guide surface are always in contact.

[0014] The technical solution of this utility model achieves efficient spatial integration by setting the guide component on the side of the base and the movable seat, thereby solving the problem of the large height of the existing optical platform along the optical axis.

[0015] This solution utilizes a limiting mechanism to ensure that the first contact part and the first guide surface always maintain contact. The limiting mechanism continuously functions to effectively prevent separation or changes in gap between the base and the guide, thereby enhancing the stability of the entire module structure.

[0016] This design also utilizes a first magnet and / or a second magnet to ensure a tight fit between the base and the movable seat, preventing separation and ensuring precise alignment. The first magnet and / or the second magnet also attract the guide component, ensuring constant contact between the second abutment portion of the movable seat and the second guide surface of the guide component. This configuration effectively prevents separation between the movable seat and the guide component, allowing the movable seat to move more stably along the trajectory of the second guide surface when moving along the second abutment portion, reducing the risk of disengagement due to lateral forces or other interference factors, and ensuring guiding accuracy.

[0017] Optionally, at least three sets of first rolling elements or sliding bosses are spaced apart between the base and the movable seat. This arrangement reduces friction between the base and the movable seat, lowers energy loss, and allows the movable seat to slide more smoothly and transmit force more evenly.

[0018] Optionally, each group of the first rolling elements includes at least one ball. The design of at least one ball in each group provides layout flexibility. The number, size, and distribution of each group of balls can be flexibly adjusted according to the specific design requirements and space constraints of the side-guided optical platform.

[0019] Optionally, the base and / or the movable seat have first limiting grooves for receiving the balls, each of the first limiting grooves being used to receive at least one of the balls. The first limiting grooves restrict the rolling element to a specific position, thereby preventing it from dislodging from the base and the movable seat during movement.

[0020] Optionally, the limiting mechanism uses a first magnetic attraction force to ensure that the first abutting part and the first guide surface are always in contact. The magnetic attraction force provides a continuous and stable force. Furthermore, the magnetic attraction force has a certain adaptive characteristic. When a slight relative displacement occurs between the guide member and the base due to external force, the magnetic attraction force will automatically adjust, causing them to return to a tight fit.

[0021] Optionally, the limiting mechanism includes: a first magnetic element disposed on the base, and the guide having a magnetic material. The first magnetic element attracts the guide, ensuring that the first abutment portion and the first guide surface are always in contact. In the above solution, by providing a first magnetic element on the base and a magnetic material on the guide, the magnetic attraction keeps the first abutment portion and the first guide surface in constant contact, providing a stable and reliable limiting effect. The magnetic attraction continues to act, ensuring that the guide and base are tightly fitted under various working conditions, thereby maintaining the precise sliding trajectory of the moving seat and achieving reliable optical image stabilization.

[0022] Optionally, the limiting mechanism uses a second magnetic attraction to ensure that the second abutting part and the second guide surface are always in contact. The beneficial effects are the same as above.

[0023] Optionally, the limiting mechanism includes a second magnetic element disposed on the movable base, and the guide member having a magnetic material. The second magnetic element attracts the guide member, ensuring that the second abutment portion and the second guide surface are always in contact. In the above solution, by providing a second magnetic element on the movable base and a magnetic material on the guide member, magnetic attraction ensures that the second abutment portion and the second guide surface are always in close contact. This magnetic attraction provides a continuous and stable force, effectively resisting various external interferences, preventing separation or gaps between the movable base and the guide member, ensuring precise sliding of the movable base under the guidance of the guide member, maintaining stable operation of the optical image stabilization function, and thus improving the stability of the captured image.

[0024] Optionally, the guide member has a first extending arm and a second extending arm perpendicular to the first extending arm. The side of the first extending arm forms the first guiding surface, and the side of the second extending arm forms the second guiding surface. In the above scheme, the guide member forms the first guiding surface and the second guiding surface through the first extending arm and the perpendicular second extending arm, respectively. This orthogonal structural design allows the moving seat to achieve precise guidance in two mutually perpendicular directions. The first and second extending arms of the guide member form an integral structure, which optimizes the spatial layout of the side-guided optical platform while realizing multi-dimensional guidance functions. This integrated design avoids the space waste caused by using multiple independent guiding components, making the entire module structure more compact. By setting the first guiding surface and the second guiding surface on the sides of the first and second extending arms, respectively, the side space of the guide member is fully utilized. This layout not only provides stable guidance for the moving seat but also makes the spatial relationship between the base, the moving seat, and the guide member more reasonable.

[0025] Optionally, the first extension arm has a first bent edge extending to the upper surface of the movable seat, and the lower surface of the first bent edge slides in engagement with the upper surface of the base.

[0026] And / or, the second extension arm has a second bent edge extending to the upper surface of the movable seat, the lower surface of the second bent edge slidingly engaging with the upper surface of the movable seat.

[0027] By adopting the above scheme, in addition to the side guidance, the sliding engagement between the lower surface of the bent edge and the upper surface of the base and the moving seat constrains the base and the moving seat from above, thus forming a multi-faceted guiding structure. This adds an extra constraint surface to the moving seat, making the degree of freedom of the moving seat during the sliding process more strictly limited, and making its movement more precise.

[0028] Optionally, at least two sets of second rolling elements are provided between the first guide surface and the base, and / or at least two sets of second rolling elements are provided between the second guide surface and the movable seat. In the above scheme, multiple sets of second rolling elements can provide precise guidance for the movable seat. Compared with sliding friction, the rolling motion of the second rolling elements causes less wear on the guide surface, the base, and the movable seat. This helps to extend the service life of the base, the movable seat, and the guide components, reduce the decrease in accuracy and the probability of failure caused by component wear, and ensure the long-term stable operation of the side-guided optical platform.

[0029] Optionally, each set of the second rolling elements includes at least one ball, and the base and / or the movable seat has a second limiting groove for receiving the ball. The ball is spherical and makes point contact with the guide surface and the abutment portion, which minimizes rolling friction resistance. As the movable seat slides along the guide surface, the ball can roll easily, further reducing the friction force on the movable seat.

[0030] Optionally, at least some of the balls in the second rolling element protrude upwards from the base. These protruding balls can support the lower surface of the guide, thereby reducing the friction between the guide and the base.

[0031] Optionally, the base has an upwardly extending boss on its side, and the first abutting portion is disposed on the side of the extending boss.

[0032] In the above scheme, the first abutment is formed by the side of the upwardly extending boss of the base, which makes the fit between the guide and the first abutment more tight and precise. During operation, the guide can abut against the base more stably and effectively resist the lateral force caused by the movement of the moving seat or external vibration.

[0033] Optionally, the side of the extension boss has a third limiting groove, and the first extension arm has a third bent edge extending into the third limiting groove, the third bent edge being movably disposed within the third limiting groove. Through the cooperation of the third bent edge and the third limiting groove, when the device is accidentally dropped or impacted, the connection between the guide and the moving base can be maintained, ensuring that the optical image stabilization function is not affected, and guaranteeing the continuity and stability of shooting.

[0034] Optionally, the movable base has a guide groove, and the second extension arm is slidably disposed within the guide groove. By providing a guide groove on the movable base, a stable connection and guiding relationship is provided for the guide component.

[0035] Optionally, the base has an electromagnetic drive mechanism for driving the movable seat to move along the first abutment portion or the second abutment portion. In the above solution, the electromagnetic drive mechanism on the base can provide precise driving force to the movable seat, enabling it to move accurately along the first abutment portion or the second abutment portion. Specifically, the electromagnetic drive can precisely adjust the magnitude and direction of the driving force by controlling the magnitude and direction of the current, thereby achieving precise control of the movable seat's movement.

[0036] This utility model also provides a camera module, including: an optical device and a side-guided optical platform as described in any of the above solutions, wherein the optical device is connected to a movable base of the side-guided optical platform.

[0037] This utility model has all the advantages of adopting the side-guided optical platform described in any of the above solutions.

[0038] This utility model also provides an electronic device, including: the camera module described in the above solution. Attached Figure Description

[0056] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0057] Example 1

[0058] like Figure 1-7 The image shows a specific embodiment of the side-guided optical platform provided in this example. Specifically, the side-guided optical platform includes: a base 1, a movable seat 2, and a guide member 3. The movable seat 2 is slidably disposed on the base 1, and the guide member 3 is disposed on the side of the base 1 and the movable seat 2.

[0059] like Figure 2 As shown, the base 1 has a first abutting portion 4, and the movable seat 2 has a second abutting portion 5. It should be noted that the first abutting portion 4 and the second abutting portion 5 can be flat surfaces, or they can be outwardly protruding protrusions or rolling elements, etc.

[0060] like Figure 4 , Figure 5 As shown, the guide member 3 has a first guide surface 6 that cooperates with the first abutting part 4, and the guide member 3 also has a second guide surface 7 that cooperates with the second abutting part 5. The first guide surface 6 and the second guide surface 7 are set at an angle.

[0061] In addition, the side-guided optical platform provided in this embodiment also includes: a limiting mechanism, which acts between the base 1 and the guide member 3 to ensure that the first abutting part 4 and the first guide surface 6 are always in contact; the limiting mechanism also acts between the guide member 3 and the movable seat 2, and to ensure that the second abutting part 5 and the second guide surface 7 are always in contact. That is, when the first abutting part 4 and the second abutting part 5 are planar, the first abutting part 4 is always in close contact with and slides against the first guide surface 6 of the guide member 3, and the second abutting part 5 is always in close contact with and slides against the second guide surface 7 of the guide member 3. When the first abutting part 4 and the second abutting part 5 are outwardly protruding protrusions or rolling elements, the protrusions or rolling elements are always in close contact with and slide against the guide member 3.

[0062] The limiting mechanism can be implemented in various ways. For example, the biasing force provided by the biasing component can be used to keep the first abutting part 4 and the first guide surface 6 in constant contact, and to keep the second abutting part 5 and the second guide surface 7 in constant contact; or, magnetic attraction can be used to achieve the above functions, etc. Therefore, no specific limitation is made here.

[0063] The side-guided optical platform provided in this embodiment achieves efficient spatial integration by having the guide component 3 cooperate with the sides of the base 1 and the movable seat 2, thus solving the problem of the large height along the optical axis in existing side-guided optical platforms. This spatial integration method not only helps to miniaturize the module but also improves the integrity and coordination of the module's internal structure. As a result, the mutual influence between components during module operation is reduced, and the operation is more stable. In addition, this solution uses a limiting mechanism to ensure that the first abutment part 4 and the first guide surface 6, and the second abutment part 5 and the second guide surface 7 always maintain a cooperative state, further enhancing the stability of the entire module structure. The continuous function of the limiting mechanism can effectively prevent the guide surface and the abutment part from separating or changing gaps, thereby ensuring the reliability of guidance.

[0064] like Figure 2 , Figure 3 As shown, in this embodiment, the limiting mechanism includes a first magnetic element 10 and a second magnetic element 11. The first magnetic element 10 is disposed on the base 1, and the guide 3 has a magnetic material that cooperates with the first magnetic element 10. The first magnetic element 10 attracts the guide 3 so that the first abutting portion 4 and the first guide surface 6 are always in contact. The second magnetic element 11 is disposed on the movable seat 2, and the guide 3 has a magnetic material that cooperates with the second magnetic element 11. The second magnetic element 11 attracts the guide 3 so that the second abutting portion 5 and the second guide surface 7 are always in contact.

[0065] In the above scheme, a first magnetic attraction force is used to keep the first abutment part 4 and the first guide surface 6 in constant engagement, and a second magnetic attraction force is used to keep the second abutment part 5 and the second guide surface 7 in constant tight engagement. This magnetic attraction force provides a continuous and stable force, which can effectively resist various external interferences, prevent separation or gaps between the guide 3 and the base 1, and between the movable seat 2 and the guide 3, and ensure that the guide 3 and the base 1 are in close contact, and the movable seat 2 and the guide 3 are in close contact, thereby maintaining the precise sliding trajectory of the movable seat 2 and achieving reliable optical image stabilization.

[0066] It should be noted that in specific embodiments where the guide member 3 has magnetic material, the guide member 3 can be entirely made of magnetic material, or the guide member 3 can be covered with magnetic material, or a magnetic body can be embedded in the guide member 3, etc., without specific limitations. In addition, in some alternative embodiments, the first magnetic element 10 and / or the second magnetic element 11 can also be disposed on the guide member 3, and the base 1 and the movable seat 2 respectively have magnetic material.

[0067] In some alternative embodiments, the second magnetic element 11 may be omitted. For example, a magnet of an electromagnetic drive mechanism may be used instead of the second magnetic element 11.

[0068] Working principle: In the side-guided optical platform provided in this embodiment, the guide member 3 cooperates with the first abutment part 4 of the base 1 through the first guide surface 6, and the second guide surface 7 cooperates with the second abutment part 5 of the movable seat 2, providing precise guidance for the movable seat 2. The limiting mechanism ensures that the guide surface and the abutment part are always in close contact through magnetic attraction (such as the attraction of the guide member 3 by the first magnetic member 10, so that the first abutment part 4 and the first guide surface 6 are always in abutment; the attraction of the guide member 3 by the second magnetic member 11 or the magnet of the electromagnetic drive mechanism, so that the second abutment part 5 and the second guide surface 7 are always in abutment), thus maintaining structural stability.

[0069] like Figure 6 As shown, in this embodiment, at least three sets of first rolling elements 8 are spaced apart between the base 1 and the movable seat 2. The arrangement of the first rolling elements 8 optimizes the force transmission method between the base 1 and the movable seat 2. During the movement of the movable seat 2, the force is transmitted through the rolling elements in the form of rolling friction. Compared with sliding friction, rolling friction has less frictional force, lower energy loss, and can transmit force more evenly. This makes the movable seat 2 slide more smoothly. Multiple sets of first rolling elements 8 can form multiple support points. Since the multiple sets of first rolling elements 8 are spaced apart, they can constrain and adjust the movement of the movable seat 2 at different positions, thus suppressing the swaying of the movable seat 2 during the sliding process. Of course, the above description is not limiting. In some alternative embodiments, at least three sets of sliding bosses can also be spaced apart between the base 1 and the movable seat 2. The sliding area between the base 1 and the movable seat 2 is reduced by the support of the sliding bosses, thereby also reducing the sliding friction between the base 1 and the movable seat 2.

[0070] like Figure 6 As shown, in this embodiment, each group of first rolling elements 8 includes two balls. The base 1 and the movable seat 2 each have a first limiting groove 9 for accommodating the balls, with each first limiting groove 9 accommodating one ball. The first limiting groove 9 restricts the rolling element to a specific position, preventing it from dislodging from the base 1 and the movable seat 2 during movement. Of course, the above description is not limiting; in some alternative embodiments, each first limiting groove 9 can also accommodate multiple balls.

[0071] In addition, in some alternative embodiments, the first limiting groove 9 may be provided only on the base 1 or only on the movable seat 2.

[0072] like Figure 3As shown, in this embodiment, the movable seat 2 has a first magnet 14 and a second magnet 15, and the base 1 has a magnetic material. The first magnet 14 and the second magnet 15 are used to attract the base 1 so that the base 1 and the movable seat 2 are always in contact. Of course, the above description is not limiting. In some alternative embodiments, the first magnet 14 and / or the second magnet 15 may be omitted.

[0073] Additionally, it should be noted that in this embodiment, the second magnet 15 is positioned directly below the second magnetic component 11. This arrangement allows the guide component 3 to be attracted through the combined action of the second magnet 15 and the second magnetic component 11, thereby improving the magnetic attraction effect. Furthermore, based on this structure, the second magnetic component 11 can also be omitted.

[0074] like Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, the guide member 3 has a first extension arm 18 and a second extension arm 19 perpendicular to the first extension arm 18. The side of the first extension arm 18 forms the first guide surface 6, and the side of the second extension arm 19 forms the second guide surface 7. This orthogonal structural design of the first guide surface 6 and the second guide surface 7 enables the movable seat 2 to obtain precise guidance in two mutually perpendicular directions. The first extension arm 18 and the second extension arm 19 of the guide member 3 form an integral structure, which optimizes the spatial layout of the side-guided optical platform while realizing multi-dimensional guidance functions. This integrated design avoids the space waste caused by using multiple independent guide components, making the entire module structure more compact. By setting the first guide surface 6 and the second guide surface 7 on the sides of the first extension arm 18 and the second extension arm 19 respectively, the side space of the guide member 3 is fully utilized. This layout not only provides stable guidance for the movable seat 2, but also makes the spatial relationship between the base 1, the movable seat 2, and the guide member 3 more reasonable.

[0075] like Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, the first extension arm 18 has a first bent edge 20 extending to the upper surface of the movable seat 2, and the lower surface of the first bent edge 20 is slidably engaged with the upper surface of the base 1; the second extension arm 19 has a second bent edge 21 extending to the upper surface of the movable seat 2, and the lower surface of the second bent edge 21 is slidably engaged with the upper surface of the movable seat 2.

[0076] By adopting the above scheme, in addition to the side guidance, the sliding cooperation between the lower surface of the bent edge and the upper surface of the movable seat 2 constrains the movable seat 2 from above, thus forming a multi-faceted guiding structure. This adds an extra constraint surface to the base 1 and the movable seat 2, making the degree of freedom of the movable seat 2 during the sliding process more strictly restricted, and making its movement more precise.

[0077] Of course, the above description is not limiting. In some alternative embodiments, the first bend edge 20 and / or the second bend edge 21 may be omitted.

[0078] like Figure 2 and Figure 3 As shown, in this embodiment, two sets of second rolling elements 16 are provided between the first abutment portion 4 of the base 1 and the first guide surface 6. Each set of second rolling elements 16 includes a ball, and the base 1 has a second limiting groove 17 for accommodating the ball. The ball is spherical, and its contact with the first guide surface 6 and the first abutment portion 4 is a point contact. This contact method results in extremely low rolling friction resistance. During the sliding process of the movable seat 2 along the first guide surface 6, the ball can roll easily, further reducing the friction force on the movable seat 2.

[0079] like Figure 2 and Figure 3 As shown, in this embodiment, at least two sets of second rolling elements 16 are provided between the second abutment portion 5 of the movable seat 2 and the second guide surface 7. Each set of second rolling elements 16 includes a ball, and the movable seat 2 has a second limiting groove 17 for accommodating the ball. The ball is spherical, and its contact with the second guide surface 7 and the movable seat 2 is a point contact, which minimizes rolling friction resistance. During the sliding of the movable seat 2 along the direction of the second guide surface 7, the ball can roll easily, further reducing the friction force on the movable seat 2.

[0080] Multiple sets of second rolling elements 16 provide precise guidance for the movable seat 2. Compared to sliding friction, the rolling motion of the second rolling elements 16 causes less wear on the guide surface and the contact portion. This helps extend the service life of the base 1, movable seat 2, and guide 3, reduces the probability of accuracy degradation and failure due to component wear, and ensures the long-term stable operation of the side-guide optical platform. Additionally, in some alternative embodiments, each set of second rolling elements 16 may also include multiple balls.

[0081] like Figure 7 As shown, in this embodiment, at least some of the balls in the second rolling element 16 protrude upwards from the base 1. This arrangement, with the balls supported below the guide member 3, reduces friction between the guide member 3 and the base 1.

[0082] Friction optimization: Multiple sets of first rolling elements 8 (each set may contain one or two balls) are arranged between the base 1 and the movable seat 2. Rolling friction replaces sliding friction, reducing friction and suppressing the shaking of the movable seat 2. Multiple sets of second rolling elements 16 (each set contains one ball) are arranged between the first guide surface 6 and the first abutment part 4, and between the second guide surface 7 and the second abutment part 5. This further reduces the friction of the movable seat 2 during the guiding process, while providing precise guidance for the movable seat 2, reducing component wear, and ensuring long-term stable operation of the module.

[0083] like Figure 2 , Figure 5 As shown, in this embodiment, the base 1 has an upwardly extending protrusion 22, and the first abutting part 4 is disposed on the side of the extending protrusion 22. This arrangement makes the fit between the guide 3 and the first abutting part 4 tighter and more precise. During operation, the guide 3 can abut more firmly against the base 1, effectively resisting the lateral force caused by the movement of the moving seat 2 or external vibration.

[0084] like Figure 5 , Figure 6 As shown, in this embodiment, the side of the extension boss 22 has a third limiting groove 23, and the first extension arm 18 has a third bent edge 24 extending into the third limiting groove 23. The third bent edge 24 is movably disposed within the third limiting groove 23. With this configuration, during the operation of the optical image stabilization module, whether it is normal movement of the moving base 2 or interference from external vibrations, impacts, etc., the third bent edge 24 is movably disposed within the third limiting groove 23, which can effectively prevent the guide member 3 from detaching from the moving base 2.

[0085] like Figure 3 , Figure 6 As shown, in this embodiment, the base 1 has an electromagnetic drive mechanism for driving the movable seat 2, so that the movable seat 2 moves along the first abutment portion 4 or the second abutment portion 5. In the above solution, the electromagnetic drive mechanism on the base 1 can provide a precise driving force to the movable seat 2, enabling the movable seat 2 to move precisely along the first abutment portion 4 or the second abutment portion 5. Specifically, the electromagnetic drive can precisely adjust the magnitude and direction of the driving force by controlling the magnitude and direction of the current, thereby achieving precise control of the displacement of the movable seat 2.

[0086] Specifically, the electromagnetic drive mechanism includes: a first electromagnetic coil 12, a second electromagnetic coil 13, a first magnet 14, and a second magnet 15. The first electromagnetic coil 12 and the second electromagnetic coil 13 are respectively disposed on the base 1, and the first magnet 14 and the second magnet 15 are respectively disposed on the movable seat 2. The first magnet 14 cooperates with the first electromagnetic coil 12, enabling the movable seat 2 to move along the extending direction of the plane containing the second abutment portion 5 when the first electromagnetic coil 12 is energized; the second magnet 15 cooperates with the second electromagnetic coil 13, enabling the movable seat 2 to move along the extending direction of the plane containing the first abutment portion 4 when the second electromagnetic coil 13 is energized.

[0087] In the above scheme, by setting a first electromagnetic coil 12 and a second electromagnetic coil 13 on the base 1, and correspondingly setting a first magnet 14 and a second magnet 15 on the movable seat 2, a precise linear drive system is formed. When the first electromagnetic coil 12 is energized, it interacts with the first magnet 14 to generate a driving force along the extension direction of the plane where the second abutment part 5 is located, which can precisely drive the movable seat 2 to move in this direction; similarly, when the second electromagnetic coil 13 is energized, it cooperates with the second magnet 15 to drive the movable seat 2 to move along the extension direction of the plane where the first abutment part 4 is located. This design enables the movable seat 2 to achieve high-precision linear motion control in two different directions.

[0088] By adopting the above scheme, the energizing state, current magnitude and direction of the first electromagnetic coil 12 and the second electromagnetic coil 13 can be controlled independently, thereby flexibly adjusting the movement speed, displacement and acceleration of the moving seat 2 in two directions.

[0089] In some embodiments, the second magnet 15 can attract the guide member 3, ensuring that the second abutment portion 5 and the second guide surface 7 are always in contact. That is, the attraction force of the second magnet 15 on the guide member 3 ensures that the second abutment portion 5 and the second guide surface 7 are always tightly fitted. This arrangement effectively prevents separation between the movable seat 2 and the guide member 3, allowing the movable seat 2 to move more stably along the trajectory of the second guide surface 7 when moving along the second abutment portion 5, reducing the risk of separation due to lateral forces or other interference factors, and ensuring the accuracy of guidance.

[0090] Driving Principle: The electromagnetic drive mechanism includes a first electromagnetic coil 12 and a second electromagnetic coil 13 mounted on the base 1, and a first magnet 14 and a second magnet 15 mounted on the movable seat 2. By controlling the energizing state, current magnitude, and direction of the first electromagnetic coil 12 and the second electromagnetic coil 13, electromagnetic interaction is utilized to drive the movable seat 2 along the extension direction of the plane containing the second abutment portion 5, with the cooperation of the first magnet 14 and the first electromagnetic coil 12. Similarly, the second magnet 15, in conjunction with the second electromagnetic coil 13, drives the movable seat 2 along the extension direction of the plane containing the first abutment portion 4, thus achieving precise control of the displacement of the movable seat 2. Simultaneously, the attraction force of the first magnet 14 and the second magnet 15 on the base 1 helps the movable seat 2 to fit tightly against the base 1, and the attraction force of the second magnet 15 on the guide member 3 ensures that the movable seat 2 fits tightly against the second guide surface 7.

[0091] Example 2

[0092] like Figure 8 , Figure 9 and Figure 10 The image shows another specific implementation of the side-guided optical platform provided in this embodiment.

[0093] In this embodiment, the movable seat 2 has a guide groove 25, and the second extension arm 19 is slidably disposed in the guide groove 25.

[0094] By providing a guide groove 25 on the movable base 2, a stable connection and guiding relationship is provided between the guide member 3 and the movable base 2. Furthermore, by using the side wall of the guide groove 25 as the second abutment part 5, the second abutment part 5 is avoided from being provided on the side of the movable base 2, thus saving circumferential space.
