The fixing component is disposed on the mounting base and has a driving mechanism and a locking member that is throttledly connected to the driving mechanism. The driving mechanism drives the locking member to move between a first position and a second position.

[0017] The present application will be further described below with reference to the accompanying drawings and some embodiments. The following embodiments are mainly used to illustrate the technical solutions of the present application and therefore should not be construed as limiting the scope of protection of the present application.

In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0020] In this document, any particular feature, structure, or characteristic described in any embodiment may be included in at least one embodiment or a combination of at least two embodiments of this application. Those skilled in the art will understand that the embodiments described herein may be combined with other embodiments herein or other embodiments outside of this document.

[0022] In the various embodiments of this application, unless otherwise expressly specified and limited, the technical terms "setting," "installing," "assembling," "connecting," "linking," and "fixing," etc., should be interpreted broadly. Taking connection as an example, it may include fixed connection, detachable connection, or integral molding; it may also include at least one of mechanical connection and electrical connection; it may include direct connection or indirect connection through an intermediate medium.

[0023] Imaging devices are widely used instruments and equipment, and can be divided into ultrasonic imaging devices, optical imaging devices, infrared imaging devices, etc., according to different working principles. In optical imaging devices, the propagation path of light can be controlled by designing the position and orientation of various optical elements to obtain the desired image.

[0024] Furthermore, optical imaging devices typically need to image different objects, which means that the optical elements within the device must be designed to be adjustable. For example, any one of the following—the distance from the optical lens to the object being observed, the angle of the optical lens, or the distance between optical lenses—can be configured to be adjustable. However, adjustable optics are more susceptible to shaking and accidental damage during transportation.

[0025] To address the aforementioned problems, this application provides an imaging device with a fixing component, which can secure key components of the imaging device during transportation, thereby reducing the possibility of damage to these key components. Furthermore, it should be noted that the fixing component of this application can be used not only for imaging devices but also for various other instruments and equipment that may be accidentally damaged due to shaking during transportation, and can similarly achieve the technical effect of reducing damage to the key components of such equipment.

[0026] See Figure 1According to one or more embodiments of this application, the imaging device 1 may include a mounting base 10, an imaging component 20, and a fixing component 30. The imaging component 20 and the fixing component 30 may be disposed on the mounting base 10. In some examples, the mounting base 10 may be used to hold a slide awaiting observation.

[0027] See Figure 1 , Figure 2 , Figure 3 and Figure 4 According to one or more embodiments of this application, the fixing component 30 may have a drive mechanism 31 and a locking member 32 pulvinctly connected to the drive mechanism 31. The drive mechanism 31 may drive the locking member 32 to move between a first position and a second position. The locking member 32 may move to the first position to abut against the imaging component 20 and fix the imaging component 20 to the mounting base 10. The locking member 32 may move to the second position to separate from the imaging component 20.

[0028] In this application, when the imaging device 1 needs to be transported, the locking member 32 can be pushed to the first position by the drive mechanism 31, thereby locking and fixing the imaging component 20 to reduce the possibility of the imaging component 20 being shaken and damaged during transportation. When the imaging device 1 needs to be operated, the locking member 32 can be pushed to the second position by the drive mechanism 31, making the position or orientation of the imaging component 20 adjustable, which is beneficial for imaging. In addition, the fixing component 30 of this application also has the function of facilitating adjustment.

[0029] According to one or more embodiments of this application, the drive mechanism 31 can drive the locking member 32 to perform linear motion to move between a first position and a second position. In this case, the range of motion of the locking member 32 can be reduced to a certain extent, thereby helping to reduce the space occupied by the fixing component 30 and thus saving space.

[0030] According to one or more embodiments of this application, the drive mechanism 31 includes a rotating shaft 311 rotatably disposed on the mounting base 10. A locking member 32 connects to the rotating shaft 311 and converts the rotational motion of the rotating shaft 311 into linear motion, allowing movement between a first position and a second position. In this case, the rotation of the drive mechanism 31 can reduce the range of motion of the drive mechanism 31 to a certain extent, thereby helping to reduce the space occupied by the drive mechanism 31 and thus saving space.

[0031] See Figure 2 , Figure 3 and Figure 4According to one or more embodiments of this application, the rotating shaft 311 has an output shaft segment 312. A locking member 32 abuts against the outer wall surface of the output shaft segment 312, and the rotating shaft 311 drives the locking member 32 to move along a direction perpendicular to the central axis of the rotating shaft 311. In a cross-section perpendicular to the central axis of the rotating shaft 311, at least two points on the outer wall surface of the output shaft segment 312 are at different distances from the central axis of the rotating shaft 311.

[0032] During the rotation of the shaft 311, the locking member 32 can contact different areas of the outer wall of the output shaft segment 312 at different times. Since the distance from different areas of the outer wall of the output shaft segment 312 to the central axis is not always the same, the output shaft segment 312 can drive the locking member 32 to move along the direction perpendicular to the central axis of the shaft 311 during the rotation.

[0033] According to one or more embodiments of this application, the output shaft segment 312 is cylindrical, and the central axis of the output shaft segment 312 is not collinear with the central axis of the rotating shaft 311. That is, the output shaft segment 312 can be eccentrically positioned, with an eccentric distance. The diameter of the output shaft segment 312 can be smaller than the diameter of the rotating shaft 311, and the circumference of the output shaft segment 312 is tangent to the rotating shaft 311.

[0034] In some alternative embodiments, the output shaft segment 312 may also be a cam structure. The cam structure may abut against the locking member 32 to drive the locking member 32 to move in a direction perpendicular to the central axis of the rotating shaft 311.

[0035] In some alternative embodiments, the locking member 32 may be integrally formed with the output shaft segment 312 to form a cam structure. The drive mechanism 31 may drive the locking member 32 to rotate together, between a first position and a second position.

[0036] See Figure 1 According to one or more embodiments of this application, the mounting base 10 has a guide hole 101. The guide hole 101 can be used to constrain the movement direction of the locking member 32. The locking member 32 is disposed within the guide hole 101 and abuts against the outer wall surface of the output shaft segment 312, and the extending direction of the guide hole 101 is perpendicular to the central axis of the rotating shaft 311. In this case, when the output shaft segment 312 rotates, it can drive the locking member 32 to move within the guide hole 101. Further, during the process of moving from the second position to the first position, the locking member 32 can gradually extend out of the guide hole 101 to abut against the imaging assembly 20.

[0037] According to one or more embodiments of this application, the mounting base 10 is further provided with a mounting groove. The rotating shaft 311 can be rotatably disposed within the mounting groove. By adjusting the coefficient of friction u of the contact area between the rotating shaft 311 and the mounting groove, the frictional force between the rotating shaft 311 and the mounting groove during rotation can be adjusted. When the rotating shaft 311, the output shaft segment 312, and the locking member 32 meet specific conditions, the rotating shaft 311 can be made to be in a self-locking state, that is, it will not rotate randomly.

[0038] As described above, the movement of the rotating shaft 311 and the locking member 32 are interrelated. In other words, when the rotating shaft 311 rotates to a first angle, the locking member 32 can be located in a first position, and when the rotating shaft 311 rotates to a second angle, the locking member 32 can be located in a second position.

[0039] See Figure 5 When the rotating shaft 311 is at the first angle, the locking member 32 abuts against the imaging component 20, and a preset angle is formed between the straight line containing the center of the output shaft segment 312 and the center of the rotating shaft 311 and the direction of gravity. This angle can be from 0 degrees to 45 degrees, and is not limited here. Assuming that when the rotating shaft 311 is at the first angle, the preset angle is α, the unlocking force on the rotating shaft 311 is F1, and the frictional force between the rotating shaft 311 and the mounting groove is F2. When F2>F1 (cos a*u>sin a), the rotating shaft 31 will not rotate randomly when the locking member 32 is in the first position. That is, when the friction coefficient u is determined, the preset angle α when the locking member 32 abuts against the imaging component 20 satisfies cos a*u>sin a, and the rotating shaft 311 is in a self-locking state.

[0040] See Figure 6 According to one or more embodiments of this application, the locking member 32 may include a first member 321 and a second member 322. The second member 322 may be fixedly disposed on the first member 321, and the second member 322 may be configured to be disposed at different positions on the first member 321. When the second member 322 is disposed at different positions on the first member 321, the total height of the first member 321 and the second member 322 is different. Specifically, the first member 321 may be threadedly connected so that the second member 322 can be disposed at different positions on the first member 321. In this case, it is convenient for operators to adjust, and even if the manufacturing precision of the locking member 32 is small, the user can adjust the total height of the first member 321 and the second member 322 so that the locking member 32 can accurately fix the imaging component 20 in the first position.

[0041] See Figure 1 and Figure 7According to one or more embodiments of this application, the drive mechanism 31 further includes a rotating handle 313, which is fixedly disposed with the rotating shaft 311. In this case, the user can manually operate the rotating handle 313 to drive the rotating shaft 311 to rotate, thereby causing the locking member 32 to move between a first position and a second position.

[0042] According to one or more embodiments of this application, a sensing element 314 is provided on the rotating shaft 311, which rotates with the rotating shaft 311, and a sensing switch 102 is provided on the mounting base 10 to sense the position of the sensing element 314. In this case, the angle of the rotating shaft 311 can be determined by the position of the sensing element 314, and thus the position of the locking member 32 can be determined. For example, in some embodiments, when the rotating shaft 311 rotates to a first position, the sensing element 314 moves to a preset position. When the sensing switch 102 detects that the sensing element 314 has moved to the preset position, it means that the locking member 32 has moved to the first position and fixed the imaging assembly 20.

[0043] According to one or more embodiments of this application, the imaging device 1 may further include a processor and an interactive component. The processor may be coupled to the interactive component and the inductive switch 102. The interactive component may include at least one of an indicator light, a display screen, and a speaker. The processor may acquire data from the inductive switch 102 to determine whether the sensing element 314 has moved to a preset position. If the determination result is yes, the processor controls the interactive component to output a corresponding prompt message. If the determination result is no, the processor may not output the above prompt message or may output a prompt message different from the above prompt message. In this way, the user can be promptly reminded whether the fixing component 30 has locked the imaging component 20, reducing the possibility of damage to the imaging device 1 during transportation if the user does not fully lock the imaging component 20.

[0044] Typically, in order to easily obtain clear images, the imaging component 20 of some imaging devices 1 is designed to be movably mounted on the mounting base 10. For example, the user can adjust the distance between the imaging component 20 and the object to be observed.

[0045] See Figure 1 and Figure 8 According to one or more embodiments of this application, a limiting member 103 spaced apart from the locking member 32 is fixedly disposed on the mounting base 10. That is, there may be a certain distance between the locking member 32 and the limiting member 103. The imaging assembly 20 may be configured to be fixed by the limiting member 103 and the locking member 32 when the locking member 32 moves to a first position.

[0046] The limiting member 103 can be used to restrict the movement range of the imaging component 20. For example, the limiting member 103 can be used to limit the imaging component 20 to an extreme position, which is reached when the imaging component 20 abuts against the limiting member 103. When the locking member 32 moves to the first position, it can abut against the imaging component 20 and make it abut against the limiting member 103, thereby fixing the imaging component 20 at the extreme position. When the locking member 32 moves to the second position, the imaging component 20 can move.

[0047] Considering that direct contact between the locking member 32 and the critical components of the imaging assembly 20 may cause damage to the critical components, the locking member 32 can abut against components other than the critical components in the imaging assembly 20 to fix them in place.

[0048] See Figure 1 and Figure 9 According to one or more embodiments of this application, the imaging assembly 20 includes a main body 21 and an adapter 22 fixed relative to the main body 21. The main body 21 may refer to the portion of the imaging assembly 20 used for imaging. For the imaging device 1, the main body 21 may include components such as an optical lens assembly; for the ultrasonic imaging device 1, the main body 21 may include components such as an ultrasonic probe. In this case, the main body 21 can be indirectly fixed by fixing the adapter 22, while also reducing the possibility of damage to the main body 21.

[0049] According to one or more embodiments of this application, the adapter 22 includes a connecting portion 221 and a limiting portion 222, wherein the connecting portion 221 connects the main body portion 21 and the limiting portion 222. The limiting portion 222 is disposed between the limiting member 103 and the locking member 32, such that when the locking member 32 moves to a first position, the limiting portion 222 is fixed by the limiting member 103 and the locking member 32, and when the locking member 32 moves to a second position, the limiting portion 222 can move between the limiting member 103 and the locking member 32.

[0050] Specifically, the adapter 22 may include a screw. The shank of the screw forms a connecting portion 221, and the head forms a limiting portion 222. The limiting member 103 may have a through hole. The screw may pass through the through hole of the limiting member 103. The outer diameter of the screw head may be larger than the inner diameter of the through hole and is located between the limiting member 103 and the locking member 32.

[0051] In some embodiments, the surface of the object to be observed is not usually perfectly flat. For example, the surface of the object to be observed may be curved, or the object to be observed may be a sample plate, and due to manufacturing errors, the sample points may not be on the same plane. In this case, when it is necessary to observe each sub-region (sample point) of the object to be observed in sequence, it is also necessary to repeatedly adjust the distance between the imaging component 20 and the sub-region to be observed so that each sub-region can fall into the appropriate area for imaging.

[0052] See Figure 8 and Figure 9 ,in, Figure 8 A schematic diagram is shown of the imaging assembly 20 observing non-coplanar sub-regions A and B of an object to be observed. According to one or more embodiments of this application, the imaging assembly 20 may further include a relative position adjustment member 40. A first end 401 of the relative position adjustment member 40 is fixedly disposed on the main body portion 21, and a second end 402 is used to abut against the sub-region to be observed. The end face of the second end 402 may at least partially protrude in a direction away from the first end 401 to form a contact micro-region 403 for abutting against the sub-region to be observed.

[0053] It should be noted that the contact micro-region 403 can be the portion of the protruding part of the end face of the second end 402 that is furthest from the first end 401, and does not necessarily need to have a strict boundary with other regions. The contact micro-region 403 can be a contact point. For example, at least part of the end face of the second end 402 can be protruded to form a conical surface or a spherical surface, and the contact point can be the apex of the conical surface or the point in the spherical surface that is furthest from the first end 401. The contact micro-region 403 can also be an arc surface, and its area can be from 0.1 square nanometers to 1 square millimeter. For example, the surface of the contact micro-region 403 can be 1 square nanometer, 16 square nanometers, 2 square micrometers, 31 square micrometers, or 150 square micrometers.

[0054] Optionally, the relative position adjustment element 40 may be configured to allow at least one of light, heat, or ultrasound to pass through, thereby reducing the possibility that the relative position adjustment element 40 may interfere with imaging.

[0055] See Figure 1 and Figure 8 According to one or more embodiments of this application, the mounting base 10 further includes an elastic element 104, one end of which abuts against the main body portion 21, and the other end abuts against the limiting member 103. The elastic element 104 can be used to adjust the interaction force when the relative position adjusting member 40 and the sub-region to be observed are in contact. Specifically, the elastic element 104 can be a spring sleeved on the screw.

[0056] In some specific embodiments, the object to be observed can be located below the imaging assembly 20. In this case, the relative position adjustment member 40 can contact the object under the weight of itself and the imaging assembly 20, and the relative position adjustment member 40 can remain in contact with the surface of the object under the weight of gravity when the object moves. However, in this case, the object may be damaged under the weight of the relative position adjustment member 40, for example, the sample surface may be damaged or the sample plate may be crushed. By using the elastic member 104, the weight of the imaging assembly 20 and the relative position adjustment member 40 can be distributed to a certain extent, thereby reducing the force between the relative position adjustment member 40 and the object, and thus protecting the object.

[0057] In some other specific embodiments, the object to be observed may be located above the imaging assembly 20. In this case, the elastic member 104 may apply an upward force to the imaging assembly 20 and the relative position adjustment member 40, overcoming the gravity of the imaging assembly 20 and the relative position adjustment member 40, so that the relative position adjustment member 40 can abut against the surface of the object to be observed located above the imaging assembly 20.

[0058] Although the various sub-regions to be observed may not be on the same plane, when each sub-region to be observed contacts the contact micro-region 403 of the relative position adjustment member 40, the distance to the first end 401 of the relative position adjustment member 40 or the imaging component 20 is always the same. In this case, when the object to be observed (e.g., a sample plate) is moved to observe the various sub-regions (e.g., sample points) within it, even if the various sub-regions to be observed may not be on the same plane, the relative position adjustment member 40, under the action of the elastic member 104, can always contact the surface of the sub-region to be observed, so that the distance from each sub-region to be observed to the imaging component 20 is always the same when being observed.

[0059] In summary, in this application, when the imaging device needs to be transported, the locking member can be pushed to the first position by the drive mechanism, thereby locking and fixing the imaging component to reduce the possibility of the imaging component being shaken and damaged during transportation; when the imaging device needs to be operated, the locking member can be pushed to the second position by the drive mechanism, making the position or attitude of the imaging component adjustable, which is beneficial for imaging. In addition, the fixing component of this application also has the function of facilitating adjustment.

[0060] Finally, it should be noted that the above embodiments are mainly used to illustrate the technical solutions of this application and should not be construed as limiting this application. The foregoing embodiments exemplarily provide a detailed and specific description of this application. Those skilled in the art can modify the technical solutions described in the foregoing embodiments or replace some or all of the technical features therein. However, these modifications or substitutions do not make the corresponding technical solutions and the technical solutions of this application constitute different inventions, and therefore should all be covered within the scope of the claims and specification of this application. In particular, in the absence of structural conflicts or binding obstacles, the various technical features mentioned in the embodiments can be combined in any way, and the technical solutions formed by these combinations should not be considered to have departed from the scope of the technical solutions of this application.
