Description

Technical Field

[0001] This application relates to the field of optical imaging equipment technology, and in particular to a binocular observation device. Background Technology

[0002] In related technologies, binocular observation equipment typically uses a focusing mechanism to synchronously focus two sets of lens assemblies, causing the focusing lenses in the two sets of lens assemblies to move simultaneously along their optical axes. That is, the two focusing lenses always move the same distance.

[0003] If two lens components are of the same type and have the same focusing parameters, synchronous focusing can adjust both focusing lenses to the appropriate position, ensuring both lens components produce a clear image. However, if the two lens components are of different types or have different focusing parameters—for example, one is a visible light lens component and the other is an infrared lens component—synchronous focusing can only adjust the focusing lens of one lens component to the appropriate position, ensuring that one lens component produces a clear image, while the other lens component cannot. If you want the other lens component to produce a clear image, you need to focus on that other lens component separately. In other words, only one lens component can be guaranteed to produce a clear image at a time, resulting in poor image quality and inconvenience. Summary of the Invention

Detailed Implementation

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.

[0024] As mentioned in the background section, existing binocular observation equipment typically uses a focusing mechanism to synchronously focus two sets of lens assemblies, causing the focusing lenses in both sets of lens assemblies to move simultaneously along their optical axes. In other words, the two focusing lenses always move the same distance.

[0025] If two lens components are of the same type and have the same focusing parameters, synchronous focusing can adjust both focusing lenses to the appropriate position, ensuring both lens components produce a clear image. However, if the two lens components are of different types or have different focusing parameters—for example, one is a visible light lens component and the other is an infrared lens component—synchronous focusing can only adjust the focusing lens of one lens component to the appropriate position, ensuring that one lens component produces a clear image, while the other lens component cannot. If you want the other lens component to produce a clear image, you need to focus on that other lens component separately. In other words, only one lens component can be guaranteed to produce a clear image at a time, resulting in poor image quality and inconvenience.

[0026] Therefore, this application provides a binocular observation device that has better imaging effect and is more convenient to use.

[0027] See Figures 1 to 3 , Figure 1 One of the perspective views of the binocular observation device provided in the embodiments of this application; Figure 2 for Figure 1 A schematic diagram showing the binocular observation equipment with its cover hidden. Figure 3 for Figure 1 The exploded view shows the third and fourth lens assemblies. The binocular observation device according to an embodiment of this application includes: A first lens assembly 100 and a second lens assembly 200, wherein the first lens assembly 100 includes a first lens 110 and a first mechanism 120 arranged sequentially along the incident direction of light, and the second lens assembly 200 includes a second lens 210 and a second mechanism 220 arranged sequentially along the incident direction of light. The first focusing mechanism 300 is connected to the first lens 110 or the first mechanism 120 and can drive the first lens 110 or the first mechanism 120 to move along the optical axis. The second focusing mechanism 400 is connected to the second lens 210 or the second mechanism 220 and can drive the second lens 210 or the second mechanism 220 to move along the optical axis. The detection component 500 is used to detect positional changes of the first focusing mechanism 300 and the second focusing mechanism 400. The display 600 is communicatively connected to the detection component 500. The display is used to display the image captured by the first lens assembly 100 when the detection component 500 detects a change in the position of the first focusing mechanism 300, and to display the image captured by the second lens assembly 200 when the detection component 500 detects a change in the position of the second focusing mechanism 400.

[0028] The ability to move the first lens 110 along the optical axis can be either moving the first lens 110 as a whole or moving a lens element within the first lens 110. Similarly, the ability to move the second lens 210 along the optical axis can be either moving the second lens 210 as a whole or moving a lens element within the second lens 210.

[0029] The binocular observation device provided in this application embodiment uses a first focusing mechanism 300 and a second focusing mechanism 400 to respectively move the lenses or mechanisms of the first lens assembly 100 and the second lens assembly 200 along the optical axis, achieving independent focusing of the first lens assembly 100 and the second lens assembly 200. This simple focusing method makes the binocular observation device easy to use. This application embodiment can adjust both the first lens assembly 100 and the second lens assembly 200 to achieve clear imaging, resulting in good imaging performance of the binocular observation device.

[0030] Furthermore, the detection component 500 is used to detect positional changes of the first focusing mechanism 300 and the second focusing mechanism 400, and is communicatively connected to the display 600. When the detection component 500 detects a positional change in the first focusing mechanism 300, the display 600 automatically displays the image captured by the first lens assembly 100. When the detection component 500 detects a positional change in the second focusing mechanism 400, the display 600 automatically displays the image captured by the second lens assembly 200. With this configuration, while the user is focusing, the binocular observation device can automatically adjust the output mode of the display 600, achieving automatic matching between the output of the display 600 and the lens assembly currently being focused, thereby effectively simplifying operation and improving the ease of use of the binocular observation device.

[0031] The lens types of the first lens assembly 100 and the second lens assembly 200 can be the same or different. For example, they can both be visible light lens assemblies, both be infrared light lens assemblies, or one can be a visible light lens assembly and the other can be an infrared light lens assembly.

[0032] like Figure 1 As shown, the first lens assembly 100 and the second lens assembly 200 are the objective lenses of the binocular observation device, located at the end closer to the object being observed. The binocular observation device includes a third lens assembly 810 and a fourth lens assembly 820. The third lens assembly 810 and the fourth lens assembly 820 are the eyepieces of the binocular observation device, located at the end furthest from the object being observed. Furthermore, the third lens assembly 810 is opposite to the first lens assembly 100, and the fourth lens assembly 820 is opposite to the second lens assembly 200.

[0033] like Figure 3 As shown, the display 600 may include a first display 610 and a second display 620. The first display 610 is located in the third lens assembly 810, and the second display 620 is located in the fourth lens assembly 820. Both the first display 610 and the second display 620 display images captured by the first lens assembly 100, or both display images captured by the second lens assembly 100.

[0034] In some embodiments of this application, see Figure 4 , Figure 4 for Figure 1 The diagram shows the binocular observation device after its housing has been concealed. The binocular observation device includes: a circuit board 900; the circuit board 900 is electrically connected to the first mechanism 120, the second mechanism 220, the detection component 500, and the display 600.

[0035] The first mechanism 120 can send the image signal captured by the first lens 110 to the circuit board 900; the second mechanism 220 can send the image signal captured by the second lens 210 to the circuit board 900. The detection component 500 can send a first detection signal to the circuit board 900 when it detects a change in the position of the first focusing mechanism 300; the detection component 500 can send a second detection signal to the circuit board 900 when it detects a change in the position of the second focusing mechanism 400.

[0036] After receiving the first detection signal, the circuit board 900 can send the image signal captured by the first lens 110 to the display 600, and after receiving the second detection signal, send the image signal captured by the second lens 210 to the display 600.

[0037] The detection component 500 can be mounted on the circuit board 900 or disposed separately from the circuit board 900; this application does not limit this. The specific location of the circuit board 900 can be as follows: Figure 4 The focus mechanism is located at the bottom of the first focusing mechanism 300 and the second focusing mechanism 400, or it can be located at the top of the first focusing mechanism 300 and the second focusing mechanism 400 or other positions. The specific arrangement can be flexibly determined according to the internal space of the binocular observation equipment.

[0038] Both the first movement 120 and the second movement 220 include an image sensor. The light captured by the lens can be transmitted to the image sensor of the corresponding movement. The image sensor converts the received light signal into an electrical signal and transmits the electrical signal to the circuit board 900.

[0039] For example, after the circuit board 900 acquires the image signals captured by the first lens 110 and the second lens 210, it sends the image signal captured by the first lens 110 to the display 600, which then displays the image captured by the first lens 110. When the user adjusts the position of the first lens 110 or the first mechanism 120 via the first focusing mechanism 300, the detection component 500 detects a change in the position of the first focusing mechanism 300 and sends a first detection signal to the circuit board 900. The circuit board 900 then sends the image signal captured by the first lens 110 to the display 600. If the image displayed on the display 600 before the user's adjustment was the image captured by the first lens 110, it continues to display the image captured by the first lens 110; if the image displayed on the display 600 before the user's adjustment was the image captured by the second lens 210, it switches to displaying the image captured by the first lens 110.

[0040] By applying the embodiments of this application, signal transmission is achieved through electrical connection between the circuit board 900 and the above-mentioned components, which simplifies the electrical connection relationship and makes control more convenient.

[0041] In some embodiments of this application, the detection component 500 may include an electrically connected position sensor and a controller. The position sensor is capable of detecting the positions of the first focusing mechanism 300 and the second focusing mechanism 400 and sending the position information to the controller. The controller is used to determine whether the positions of the first focusing mechanism 300 and the second focusing mechanism 400 have changed. Taking the detection of the first focusing mechanism 300 as an example, if the position sensor detects that the first focusing mechanism 300 is in a first position at a first time and in a second position at a second time, the controller compares the first position and the second position. If the first position is different from the second position, it is determined that the position of the first focusing mechanism 300 has changed.

[0042] The controller is electrically connected to the circuit board 900. When it determines that the position of the first focusing mechanism 300 has changed, it sends a first detection signal to the circuit board 900; when it determines that the position of the second focusing mechanism 400 has changed, it sends a second detection signal to the circuit board 900.

[0043] Using the embodiments of this application, position changes of the first focusing mechanism 300 and the second focusing mechanism 400 are detected through a position sensor and a controller, resulting in a relatively simple structure. The position sensor can detect the position of the first focusing mechanism 300 and the second focusing mechanism 400 by acquiring the position of any part of each in real time, thus allowing for flexible placement of the position sensor. The controller can be mounted on the circuit board 900 or separated from it, making its placement flexible as well.

[0044] In some embodiments of this application, see Figure 5 , Figure 5 for Figure 1 One of the cross-sectional views of the binocular observation device shown. The detection component 500 includes a sensor 510 and a trigger 520; the trigger 520 is disposed on the first focusing mechanism 300 and the second focusing mechanism 400; the sensor 510 can determine the position change of the first focusing mechanism 300 after determining that the position between itself and the trigger 520 on the first focusing mechanism 300 has changed; and can determine the position change of the second focusing mechanism 400 after determining that the position between itself and the trigger 520 on the second focusing mechanism 400 has changed.

[0045] The specific location of the trigger 520 on the first focusing mechanism 300 and the second focusing mechanism 400 is not limited in this application, as long as the trigger 520 is within the sensing range of the sensor 510. The sensor 510 is electrically connected to the circuit board 900, and can be installed separately from the circuit board 900, or it can be installed as follows: Figure 5 The cables are arranged on the circuit board to reduce the number of cables in the binocular inspection device, making the internal structure of the binocular inspection device simple and neat.

[0046] When the first focusing mechanism 300 and the second focusing mechanism 400 move their corresponding lenses or camera mechanisms, the trigger elements 520 on them also move accordingly. When the sensor 510 detects the movement of the trigger element 520 on the first focusing mechanism 300, it sends a first detection signal to the circuit board 900; when it detects the movement of the trigger element 520 on the second focusing mechanism 400, it sends a second detection signal to the circuit board 900.

[0047] In this embodiment of the application, since the trigger 520 has a small structure, the sensor 510 does not need a large sensing range. However, directly detecting the larger first focusing mechanism 300 and second focusing mechanism 400 would require a large sensing range, which could lead to misjudgment due to the detection of changes in the position of other components. Therefore, this embodiment of the application uses the sensor 510 to detect changes in the position of the trigger 520, thereby detecting changes in the position of the first focusing mechanism 300 and the second focusing mechanism 400. This results in more accurate detection and reduces the risk of misjudgment.

[0048] The number of trigger elements 520 is at least two, respectively disposed on the first focusing mechanism 300 and the second focusing mechanism 400. This application will subsequently describe the application using an example of two trigger elements 520. The number of sensing elements 510 can be one, with both trigger elements 520 within the sensing range of the sensing element 510. When the sensing element 510 detects a positional change in the trigger element 520 on the first focusing mechanism 300, it sends a first detection signal to the circuit board 900; when it detects a positional change in the trigger element 520 on the second focusing mechanism 400, it sends a second detection signal to the circuit board 900. In other embodiments of this application, the number of sensing elements 510 and trigger elements 520 can be the same, such as... Figure 4 As shown, there are two sensors 510 and two triggers 520. One sensor 510 is used to detect the position change of the trigger 520 on the first focusing mechanism 300, and the other sensor 510 is used to detect the position change of the trigger 520 on the second focusing mechanism 400.

[0049] In some embodiments of this application, the sensing element 510 is a photoelectric sensor, and the trigger element 520 is a baffle. The photoelectric sensor is fixed on the circuit board 900 and electrically connected to the circuit board 900; the baffle is fixed on the first focusing mechanism 300 and the second focusing mechanism 400 and extends toward the circuit board 900.

[0050] Specifically, the photoelectric sensor can be a slot-type photoelectric sensor, having a U-shaped slot with its opening facing the baffle. A laser emitter and a receiver are respectively mounted on opposite sides of the U-shaped slot. When the baffle is in the U-shaped slot, it can block the laser emitted by the laser emitter from the receiver. Taking the first focusing mechanism 300 as an example, when the baffle enters or leaves the U-shaped slot under the action of the first focusing mechanism 300, the slot-type photoelectric sensor can send a first detection signal to the circuit board 900.

[0051] The number of slotted photoelectric sensors can be one or more. Multiple slotted photoelectric sensors can be arranged adjacent to each other in a direction parallel to the optical axis, so that the U-shaped slots of each sensor form a detection groove with a certain thickness in the direction parallel to the optical axis. As long as one U-shaped slot senses a change in the position of the baffle, it can be determined that the first focusing mechanism 300 has a positional change. This arrangement increases the sensing range, improves detection accuracy, and reduces the risk of misjudgment caused by detection errors.

[0052] This application does not limit the type of photoelectric sensor. In other embodiments of this application, the photoelectric sensor may also be a through-beam sensor, in which the laser emitter and receiver are placed separately, and the baffle between the laser emitter and receiver can block the laser light emitted from the laser emitter to the receiver. The way the through-beam sensor detects the change in the position of the baffle, as well as the number and arrangement of the through-beam sensors, can be the same as the slotted photoelectric sensor described above, and will not be repeated here.

[0053] In some embodiments of this application, such as Figure 5 As shown, the sensing element 510 is a magnetic sensor, and the trigger element 520 is a magnetic element; the trigger element 520 is located within the sensing range of the sensing element 510.

[0054] The specific placement of magnetic components and magnetic sensors can be as follows: Figure 4 and Figure 5 As shown, the trigger 520 is disposed on the side of the first focusing mechanism 300 and the second focusing mechanism 400 facing the circuit board 900, and the sensing element 510 is disposed on the circuit board 900, electrically connected to the circuit board 900, and opposite to the trigger 520. When the magnetic element moves relative to the magnetic sensor, the magnetic sensor can detect the change in magnetic field and send a corresponding detection signal to the circuit board 900.

[0055] like Figure 5 As shown, the magnetic component and the magnetic sensor are currently in a vertically opposite state. When the magnetic component moves along a direction parallel to the optical axis under the drive of the first focusing mechanism 300 or the second focusing mechanism 400, the magnetic component can move to at least partially opposite the magnetic sensor, so that the magnetic sensor can detect the change in magnetic field. The magnetic component can also move to completely separate itself from the magnetic sensor, as long as the magnetic component is still within the sensing range of the magnetic sensor.

[0056] In other embodiments of this application, the magnetic component and the magnetic sensor can be spaced apart along a direction parallel to the optical axis, i.e., facing each other back and forth along a direction parallel to the optical axis. The magnetic component is fixed to the first focusing mechanism 300 and the second focusing mechanism 400, and the magnetic sensor can be separately disposed from the circuit board 900 and fixed to the housing 10 of the binocular observation device. When the magnetic component moves along a direction parallel to the optical axis under the drive of the first focusing mechanism 300 or the second focusing mechanism 400, the distance between the magnetic component and the magnetic sensor changes, causing the magnetic sensor to detect the change in magnetic field.

[0057] In this embodiment of the application, the detection component 500 detects positional changes of the first focusing mechanism 300 and the second focusing mechanism 400 through magnetic induction, making the detection more accurate and reducing the risk of misjudgment due to detection errors. The magnetic sensor can directly determine whether there is a positional change in the first focusing mechanism 300 and the second focusing mechanism 400, without needing to detect the specific position and then have the controller determine whether there is a positional change. This results in a rapid response, improved detection efficiency, and allows the display 600 to switch to displaying the image captured by the lens component currently being focused more quickly during focusing.

[0058] In some embodiments of this application, such as Figure 4 As shown, the first focusing mechanism 300 includes: a first focusing knob 310 and a first transmission mechanism 320; the first end of the first transmission mechanism 320 is connected to the first focusing knob 310 in a transmission connection, and the second end is connected to the first lens 110 or the first mechanism 120. The second focusing mechanism 400 includes: a second focusing knob 410 and a second transmission mechanism 420; the first end of the second transmission mechanism 420 is connected to the second focusing knob 410, and the second end is connected to the second lens 210 or the second mechanism 220. Rotating the first focusing knob 310 causes the first lens 110 or the first camera module 120 to move along the optical axis via the first transmission mechanism 320; rotating the second focusing knob 410 causes the second lens 210 or the second camera module 220 to move along the optical axis via the second transmission mechanism 420. The detection component 500 is used to detect position changes of the first transmission mechanism 320 and the second transmission mechanism 420, or the detection component 500 is used to detect position changes of the first focusing knob 310 and the second focusing knob 410.

[0059] The binocular observation device of this application embodiment uses a first transmission mechanism 320 and a second transmission mechanism 420 to pull the corresponding lens or mechanism, thereby adjusting the distance between the imaging surfaces of the lens and the mechanism, thus achieving focal length adjustment. This allows the binocular observation device to present clear images in different scenarios. Furthermore, rotating the first focusing knob 310 enables the first lens assembly 100 to form a clear image, and rotating the second focusing knob 410 enables the second lens assembly 200 to form a clear image. This simplifies the focusing process. When the first lens assembly 100 and the second lens assembly 200 are of different types or have different focusing parameters, the above adjustment process can be used to adjust the lenses or mechanisms of both the first lens assembly 100 and the second lens assembly 200 to appropriate positions, ensuring clear imaging of both and improving the imaging effect of the binocular observation device.

[0060] Specifically, in Figure 4In the illustrated embodiment, the first transmission mechanism 320 is connected to the first lens 110, and the second transmission structure 420 is connected to the second lens 210. Both the first lens 110 and the second lens 210 include lens modules. The transmission mechanism can drive the entire lens module to move, or it can drive one or more lenses in the lens module to move; this application does not limit this. In other embodiments of this application, the first transmission mechanism 320 may be connected to the first movement 120, and the second transmission structure 420 may be connected to the second movement 220; or one transmission mechanism may be connected to the lens, and the other transmission mechanism may be connected to the movement; this application does not limit this.

[0061] In this embodiment, the trigger 520 of the detection component 500 can be disposed on the first transmission mechanism 320 and the second transmission mechanism 420. The sensing element 510 detects the positional changes of the first transmission mechanism 320 and the second transmission mechanism 420 by detecting the axial movement of the first transmission mechanism 320 and the second transmission mechanism 420. Alternatively, the trigger 520 can also be disposed on the first focusing knob 310 and the second focusing knob 410, and the sensing element 510 detects the positional changes of the first transmission mechanism 320 and the second transmission mechanism 420 by detecting the rotation of the first focusing knob 310 and the second focusing knob 410, making the layout of the detection component 500 flexible. This application will subsequently describe the detection of the axial movement of the first transmission mechanism 320 and the second transmission mechanism 420 by the detection component 500 as an example.

[0062] In some embodiments of this application, such as Figure 4 As shown, the binocular observation device includes: a focusing axis 700; the focusing axis 700 is located between the first lens assembly 100 and the second lens assembly 200, and is set in a direction parallel to the optical axis; The first focusing knob 310 is fixedly sleeved on the focusing shaft 700 and can rotate around the axial direction of the focusing shaft 700; the second focusing knob 410 is rotatably sleeved on the focusing shaft 700 and can rotate around the axial direction of the focusing shaft 700.

[0063] In the embodiments of this application, both the first focusing knob 310 and the second focusing knob 410 are sleeved on the focusing shaft 700, making the structure of the binocular observation device simple and compact. The first focusing knob 310 is fixedly sleeved on the focusing shaft 700, while the second focusing knob 410 is rotatably sleeved on the focusing shaft 700. This means that when the first focusing knob 310 is rotated, the rotation of the focusing shaft 700 is not restricted by the second focusing knob 410, thus realizing independent focusing of the first lens assembly 100 and the second lens assembly 200.

[0064] The first focusing knob 310 and the second focusing knob 410 can be used as follows: Figure 4As shown, the first and second focusing knobs 310 and 410 are arranged adjacent to each other on the focusing axis 700, or they can be arranged at intervals; this application does not limit this arrangement. When arranged adjacently, the adjacent end faces of the first focusing knob 310 and the second focusing knob 410 are fitted together and arranged compactly in the axial direction, enabling focusing with one hand without moving the knob, which is convenient for the user's focusing operation. Furthermore, the first focusing knob 310 and the second focusing knob 410 can rotate relatively independently around the axial direction of the focusing axis 700 without interfering with each other. This application does not limit the relative positional relationship between the first focusing knob 310 and the second focusing knob 410. The second focusing knob 410 can be located on the side of the first focusing knob 310 away from the first lens assembly 100 and the second lens assembly 200, or it can be arranged as shown in the image. Figure 4 The first focusing knob 310 is located on the side near the first lens assembly 100 and the second lens assembly 200, as shown. This application will subsequently describe the application using the example of the second focusing knob 410 being located on the side of the first focusing knob 310 near the first lens assembly 100 and the second lens assembly 200.

[0065] The outer contours of the first focusing knob 310 and the second focusing knob 410 can be the same or different. Figure 4 In the illustrated embodiment, the outer surface of the first focusing knob 310 has multiple first protrusions spaced circumferentially. The outer surface of the second focusing knob 410 has multiple second protrusions. The different numbers and shapes of the two types of protrusions facilitate user differentiation and memorization of the lens components corresponding to the two focusing knobs, thereby enabling faster and more accurate rotation of the focusing knob corresponding to the lens component to be focused. Furthermore, the first and second protrusions also serve an anti-slip function. In other embodiments of this application, the outer contour forms of the first focusing knob 310 and the second focusing knob 410 can be interchanged, or other outer contour forms can be used.

[0066] In some embodiments of this application, see Figure 6 , Figure 6 for Figure 1 The diagram shows a perspective view of the housing. The binocular observation device includes: housing 10. A receiving cavity 12 is provided inside the housing 10.

[0067] Among them, such as Figure 2As shown, the housing 10 may include a front housing 101, a middle housing 102, and a rear housing 103 arranged sequentially along the light incident direction. A first lens assembly 100 and a second lens assembly 200 are arranged side-by-side at a distance from each other in the receiving cavity 12 of the front housing 101. The middle housing 102 is a gripping area, and a first focusing mechanism 300 and a second focusing mechanism 400 are disposed in the middle housing 102, partially within the receiving cavity 12 and partially outside the middle housing 102. A detection assembly 500 and a circuit board 900 are disposed in the receiving cavity 12 of the middle housing 102, with the circuit board 900 located at the bottom of the first focusing mechanism 300 and the second focusing mechanism 400. A third lens assembly 810 and a fourth lens assembly 820 are located outside the receiving cavity 12 and are arranged side-by-side at a distance from each other on the side of the rear housing 103 away from the front housing 101. The display 600 located in the third lens assembly 810 and the fourth lens assembly 820 can be electrically connected to the circuit board 900 in the receiving cavity 12 via a cable passing through a through hole on the rear housing 103.

[0068] like Figure 1 and Figure 2 As shown, the housing 10 includes a cover plate 13, which is located in the middle housing 102 region and covers the top of the receiving cavity 12. The cover plate 13 is provided with multiple function buttons 131, such as a power button, menu button, menu page turning button, shooting button, and laser rangefinder button. The function buttons 131 pass through the cover plate 13 and are electrically connected to the circuit board 900 to control the circuit board 900 as needed. With this arrangement, the circuit board 900 is positioned close to the first sensor 120, the second sensor 220, the detection component 500, the display 600, and the function buttons 131, avoiding complex internal wiring and simplifying the internal structural layout of the binocular observation device.

[0069] Since both the first focusing knob 310 and the second focusing knob 410 are located in the middle shell 102 area, when using the binocular observation device, the user can hold the middle shell 102 and, when focusing is required, simply move one finger to rotate the first focusing knob 310 or the second focusing knob 410, making it quite convenient to use.

[0070] See Figure 7 , Figure 7This is a second perspective view of the binocular observation device provided in the embodiments of this application. The binocular observation device further includes: a supplementary lighting module 1010 and a laser ranging module 1020. The supplementary lighting module 1010 and the laser ranging module 1020 are fixed to the housing 10, located between the first lens assembly 100 and the second lens assembly 200, and located at the ends of the first focusing mechanism 300 and the second focusing mechanism 400 closer to the first lens assembly 100 and the second lens assembly 200. The supplementary lighting module 1010 is used to provide auxiliary illumination when the light is dim, so as to improve the imaging effect of the binocular observation device; the laser ranging module 1020 is used to measure the distance between the binocular observation device and the observed object.

[0071] The middle shell 102 may be provided with a cable interface for electrical connection to external devices. A waterproof cover 14 may be provided at the cable interface to seal it. The middle shell 102 may also be provided with a bracket interface 15 to facilitate the mounting of the binocular observation equipment on a bracket, such as a tripod.

[0072] See Figure 8 , Figure 8 for Figure 1 The second cross-sectional view of the binocular observation device shown. Figure 5 and Figure 8 As shown, the housing 10 has a fixing plate 11, which can be located in the middle housing 102 area; the fixing plate 11 is rotatably sleeved on the focusing shaft 700, ensuring that the rotation of the focusing shaft 700 is not restricted by the housing 10; the first focusing knob 310, the second focusing knob 410 and the fixing plate 11 are arranged sequentially on the focusing shaft 700 along the first direction x; the first direction x is opposite to the incident direction of the light. The first transmission mechanism 320 is located on the side of the fixed plate 11 away from the first focusing knob 310, and its first end is connected to the first focusing knob 310 via the focusing shaft 700. The first end of the second transmission mechanism 420 is located on the side of the fixed plate 11 near the second focusing knob 410 and is connected to the second focusing knob 410 in a transmission manner. Its second end passes through the fixed plate 11 and is connected to the second lens 210 or the second mechanism 220.

[0073] Specifically, such as Figure 8As shown, the first focusing knob 310 is fixed to the first end of the focusing shaft 700 along the first direction x, and is fixedly connected to the focusing shaft 700 by threaded fasteners. One end face of the second focusing knob 410 along the axial direction is in contact with the first focusing knob 310, and the other end face is in contact with the fixing plate 11, and is closed by the fixing plate 11, making the binocular observation device compact in structure and simple in appearance. The end of the focusing shaft 700 along the first direction x extends out from the fixing plate 11 and is connected to the first transmission mechanism 320. With the above arrangement, the first focusing mechanism 300 and the second focusing mechanism 400 are arranged more compactly in axial length, and the axial length of the focusing shaft 700 can be set to be shorter.

[0074] In this embodiment, torque transmission between the first focusing knob 310 and the first transmission mechanism 320 is achieved through the focusing shaft 700. This allows torque transmission without direct contact between the first focusing knob 310 and the first transmission mechanism 320, making the arrangement of the first transmission mechanism 320 more flexible. Furthermore, compared to transmitting torque through multiple components, torque transmission via the focusing shaft 700 reduces power loss and improves the transmission efficiency between the first focusing knob 310 and the first transmission mechanism 320. In this embodiment, the first transmission mechanism 320 is located outside the first focusing knob 310 and the second focusing knob 410, without occupying their internal space. This allows for smaller radial dimensions of the first focusing knob 310 and the second focusing knob 410, resulting in a compact structure and convenient assembly. Moreover, subsequent maintenance of the first transmission mechanism 320 does not require disassembling the structures on the side of the fixing plate 11 near the first focusing knob 310, making maintenance more convenient.

[0075] like Figure 6 As shown, the fixed plate 11 is provided with a first through hole 111 and a second through hole 112. The focusing shaft 700 passes through the first through hole 111, and the second transmission mechanism 420 passes through the second through hole 112. The fixed plate 11 can limit the shaking of the focusing shaft 700 through the first through hole 111, allowing the focusing shaft 700 to rotate around its axis; the fixed plate 11 can limit the shaking of the second transmission mechanism 420 through the second through hole 112, guiding the second transmission mechanism 420 to move axially. By limiting the focusing shaft 700 and the second transmission mechanism 420 through the through holes on the fixed plate 11, shaking is reduced, resulting in high focusing accuracy and stability of the binocular observation device during focusing; moreover, the through hole structure is simple and easy to process; no additional limiting structure is required, making the binocular observation device simple in structure and easy to assemble.

[0076] In some embodiments of this application, see Figure 9 , Figure 9 for Figure 2The diagram shows the connection between the first and second focusing mechanisms. Figure 4 and Figure 9 As shown, the first transmission mechanism 320 includes: a first focusing bracket 321 and a first connecting rod 322; The first focusing bracket 321 is sleeved on the focusing shaft 700 and is connected to the first focusing knob 310 through the focusing shaft 700. The first focusing bracket 321 and the focusing shaft 700, one of which is provided with a curved groove extending along the axial direction, and the other is provided with a protrusion movably installed in the curved groove; or, the first focusing bracket 321 and the focusing shaft 700 are threadedly connected; the first focusing bracket 321 converts the rotation of the focusing shaft 700 into its own axial movement by means of the cooperation of the curved groove and the protrusion, or by means of the threaded connection. One end of the first connecting rod 322 is fixedly connected to the first focusing bracket 321, and the other end is fixedly connected to the first lens 110 or the first mechanism 120. When the first focusing knob 310 is turned, the focusing shaft 700 rotates and drives the first focusing bracket 321 to move along the optical axis, which in turn drives the first lens 110 or the first mechanism 120 to move along the optical axis via the first connecting rod 322.

[0077] Using the embodiments of this application, the first connecting rod 322 can realize the transmission between the first focusing bracket 321 and the first lens 110 or the first mechanism 120 of the first lens assembly 100; and the first lens assembly 100 can restrict the rotation of the first connecting rod 322, thereby restricting the first focusing bracket 321 to rotate with the focusing shaft 700, without the need to set an additional limiting mechanism to restrict the rotation of the first focusing bracket 321, making the structure of the first transmission mechanism 320 relatively simple.

[0078] In this embodiment, the first focusing bracket 321 converts the rotation of the focusing shaft 700 into its own axial movement through one of the two connection methods described above. This results in fewer parts and a simpler structure for the first transmission mechanism 320, making it easier to process and assemble. Using a threaded connection simplifies the installation of the first focusing bracket 321 and makes the connection more stable. It avoids relative wobbling during transmission between the focusing shaft 700 and the first focusing bracket 321, improving the stability of the transmission mechanism 320 and enabling the binocular observation device to have higher focusing accuracy and stability during focusing.

[0079] In this embodiment, torque transmission between the first focusing knob 310 and the first focusing bracket 321 is achieved through the focusing shaft 700. Compared with transmitting torque through multiple components, this reduces power loss and improves the transmission efficiency between the first focusing knob 310 and the first focusing bracket 321. Furthermore, torque transmission between the first focusing knob 310 and the first focusing bracket 321 does not require direct contact, making the arrangement of the first focusing bracket 321 more flexible.

[0080] The trigger 520 can be mounted on the first focusing bracket 321 or the first connecting rod 322. Driven by either the first focusing bracket 321 or the first connecting rod 322, the trigger 520 moves relative to the sensor 510 along the optical axis. Figure 4 and Figure 9 As shown, when the trigger 520 is a magnetic component, the first focusing bracket 321 is provided with a first slot 3213 for fixing and installing the magnetic component. This application does not limit the specific structure of the first slot 3213, as long as it can accommodate the magnetic component.

[0081] In some embodiments of this application, such as Figure 4 and Figure 9 As shown, the first transmission mechanism 320 includes: a first guide rod 323; the first guide rod 323 is arranged in a direction parallel to the optical axis and is fixedly connected to the housing 10; The first focusing bracket 321 has a first guide hole 3210, and the first guide rod 323 passes through the first guide hole 3210.

[0082] In this embodiment, a first guide rod 323 fixedly connected to the housing 10 restricts the rotation of the first focusing bracket 321 and guides its axial movement, ensuring that the first focusing bracket 321 always moves axially. This results in the first focusing mechanism 300 having high focusing accuracy and stability during focusing. Compared to the first transmission mechanism 320, which uses only a first connecting rod 322 to connect to the first lens 110 or the first camera module 120 for rotational limiting, this embodiment avoids the first connecting rod 322 from wobbling due to a tendency for the end connected to the first focusing bracket 321 to rotate while the end connected to the first lens 110 or the first camera module 120 remains stationary. This reduces the risk of the first connecting rod 322 wobbling and affecting focusing accuracy, and extends its lifespan.

[0083] In some embodiments of this application, see Figure 10 and Figure 11 , Figure 10 for Figure 4 A three-dimensional view of the focusing axis shown; Figure 11 for Figure 8A partially enlarged view of the binocular observation device shown. The focusing axis 700 has a first shoulder 701 and a second shoulder 702 protruding from it; the first shoulder 701 and the second shoulder 702 are arranged along a first direction x. The first focusing bracket 321 has a first limiting member 3211 and a second limiting member 3212; the first limiting member 3211 is located on the side of the first shoulder 701 near the fixing plate 11 and can be limited and engaged with the end face of the first shoulder 701; the second limiting member 3212 is located on the side of the second shoulder 702 away from the fixing plate 11 and can be limited and engaged with the end face of the second shoulder 702.

[0084] The axial distance between the first limiting member 3211 and the second limiting member 3212 is the movable distance of the first focusing bracket 321 on the focusing axis 700, which is also the movable distance of the first lens 110 or the first mechanism 120.

[0085] By applying the embodiments of this application, the axial movement range of the first focusing bracket 321 is limited by setting the first limiting member 3211 and the second limiting member 3212, and the structure is relatively simple.

[0086] exist Figure 11 In the embodiment shown, the first limiting member 3211 is the end face of the first focusing bracket 321. When the first focusing bracket 321 moves to the extreme position away from the first focusing knob 310, the end face of the first focusing bracket 321 abuts against the end face of the first shoulder 701.

[0087] The second limiting member 3212 is a protrusion on the inner wall of the first focusing bracket 321. When the first focusing bracket 321 moves to its extreme position near the first focusing knob 310, the protrusion abuts against the end face of the second shoulder 702. The second shoulder 702 can be the end face of the focusing shaft 700. Specifically, the protrusion can be a screw. After the first focusing bracket 321 is fitted onto the focusing shaft 700, the screw is screwed in from the outer wall, so that it protrudes from the inner wall of the first focusing bracket 321.

[0088] In other embodiments of this application, the structural forms of the first limiting member 3211 and the second limiting member 3212 may be interchanged or the same structural form may be used. This application does not limit the scope of the invention.

[0089] In some embodiments of this application, such as Figure 8 and Figure 11 As shown, the second transmission mechanism 420 includes: a movable part 421 and a curved cylinder 422; The movable part 421 is sleeved on the focusing shaft 700 and can move along the axial direction of the focusing shaft 700; the curved cylinder 422 is sleeved between the movable part 421 and the second focusing knob 410, and is fixedly connected to the second focusing knob 410, and can rotate around the axial direction of the focusing shaft 700. The curved cylinder 422 has a curved groove 4221 on its wall. The first end of the movable part 421 is slidably connected to the curved groove 4221, and the second end is connected to the second lens 210 or the second mechanism 220. When the curved cylinder 422 rotates, it can convert its own rotation into the axial movement of the movable part 421 through the curved slide 4221, so that the movable part 421 drives the second lens 210 or the second mechanism 220 to move axially.

[0090] In the embodiments of this application, rotation is converted into axial movement through the transmission of the movable part 421 and the curved cylinder 422, making the structure of the second transmission mechanism 420 simple and easy to process and assemble. The nested arrangement of the movable part 421 and the curved cylinder 422 can shorten the length occupied by the second transmission mechanism 420 on the focusing shaft 700, making the structure more compact.

[0091] The first focusing knob 310, the second focusing knob 410, the first transmission mechanism 320, and the second transmission mechanism 420 are all mounted on the focusing shaft 700 and are coaxially arranged. This simplifies the installation and maintenance of the first focusing mechanism 300 and the second focusing mechanism 400, and also prevents the above-mentioned components from vibrating and shifting when the focusing shaft 700 rotates. This makes the above-mentioned components stable when rotating or moving axially around the focusing shaft 700, thereby giving the binocular observation equipment high focusing accuracy and stability when focusing.

[0092] The first end of the movable part 421 of the second transmission mechanism 420 is located inside the second focusing knob 410, and the second end passes through the fixing plate 11 and is connected to the second lens 210 or the second mechanism 220. That is, the first end of the movable part 421 and the second focusing knob 410 share the axial length space of the focusing shaft 700, which can improve the space utilization rate. It does not need to occupy the area of ​​the focusing shaft 700 that extends out of the second focusing knob 410, so that the axial length of the focusing shaft 700 can be set to be shorter, and the second focusing mechanism 400 is more compact in the axial direction.

[0093] The first focusing knob 310 has an opening on the side facing the second focusing knob 410. The movable member 421 and the curved cylinder 422 pass through the opening and extend into the receiving cavity inside the first focusing knob 310, leaving space for the movable member 421 to move axially and improving space utilization.

[0094] The fixed connection between the curved cylinder 422 and the second focusing knob 410 can be a snap-fit ​​connection; see [link to details]. Figure 12 , Figure 12 for Figure 9 An exploded view of the second focusing mechanism (connecting components not shown). Figure 12As shown, at least one limiting groove 411 is provided on the end face of the second focusing knob 410, and the opening of the limiting groove 411 faces the interior of the second focusing knob 410. The curved cylinder 422 is provided with the same number of limiting protrusions 4222 on the corresponding end face. The limiting protrusions 4222 are inserted into the limiting grooves 411 in the axial direction, so that the curved cylinder 422 and the second focusing knob 410 are engaged, thereby realizing the synchronous rotation of the curved cylinder 422 and the second focusing knob 410.

[0095] In some embodiments of this application, such as Figure 11 and Figure 12 As shown, a base 423 is fitted between the movable part 421 and the focusing shaft 700; the base 423 is rotatably connected to the focusing shaft 700; the end of the base 423 is fixedly connected to the fixing plate 11; a limiting waist hole 4231 parallel to the focusing shaft 700 is provided on the outer wall of the base 423; the third end of the movable part 421 is slidably connected to the limiting waist hole 4231, so that the movable part 421 can move along the axial direction of the focusing shaft 700 when the curved cylinder 422 rotates.

[0096] Since the base 423 is fixedly connected to the fixing plate 11 of the housing 10, when the second focusing knob 410 is rotated, the base 423 remains stationary. The limiting waist hole 4231 on the base 423 restricts the rotation of the movable part 421 so that the movable part 421 can move along the axial direction of the focusing shaft 700 when the curved cylinder 422 rotates.

[0097] By applying the embodiments of this application, a base 423 is provided, and a limiting waist hole 4231 is opened on the base 423 to limit and guide the movable part 421, restricting the rotation of the movable part 421, thereby realizing the conversion of the rotation of the curved cylinder 422 into the axial movement of the movable part 421. The method of slotting the base 423 and the curved cylinder 422 to cooperate with the movable part 421 makes the structure of the second focusing knob 410 simple and easy to manufacture. The base 423, the movable part 421, the curved cylinder 422, and the second focusing knob 410 are nested layer by layer, making the internal structure of the second focusing knob 410 compact and easy to assemble. This shortens the axial space occupied by the second transmission mechanism 420, making the structure of the second focusing knob 410 more compact in the axial direction, and allowing the axial length of the focusing shaft 700 to be set shorter.

[0098] like Figure 12 As shown, the end of the base 423 that is connected to the fixing plate 11 protrudes outward in the radial direction to form a base connecting plate 4232. The base connecting plate 4232 is fitted to the fixing plate 11, so that the base 423 and the fixing plate 11 have a large contact area, preventing the moving part 421 from rotating due to the loosening of the base 423, thereby ensuring high focusing accuracy.

[0099] The base connecting plate 4232 is used to cooperate with the fixed plate 11 to clamp the curved cylinder 422 and the second focusing knob 410, preventing the curved cylinder 422 from moving axially. The base connecting plate 4232 is provided with a through area so that the movable part 421 can pass through the base 423 and be fixedly connected to the second lens 210 or the second mechanism 220.

[0100] The specific implementation method of the rotatable connection between the base 423 and the focusing shaft 700 is as follows: Figure 11 As shown, a bearing 425 is fitted between the base 423 and the focusing shaft 700. The inner ring of the bearing 425 is tightly fitted with the focusing shaft 700, and the outer ring is tightly fitted with the base 423 to achieve a rotatable connection and prevent the rotation of the focusing shaft 700 from being restricted by the second transmission mechanism 420 when the first focusing knob 310 is turned.

[0101] The quantity of bearing 425 is not limited in this application. Figure 11 In the illustrated embodiment, there are two bearings 425, and a bearing bracket 426 is provided between the two bearings 425. The bearing bracket 426 presses the bearing 425 located near the fixed plate 11 against the third shoulder 703 protruding on the focusing shaft 700; the end face of the connection end between the first focusing knob 310 and the focusing shaft 700 presses the bearing 425 located away from the fixed plate 11 against the bearing bracket 426, thus achieving axial positioning of the two bearings 425. Figure 11 As shown, if the diameter of the end face of the connection between the first focusing knob 310 and the focusing shaft 700 is smaller than the diameter of the bearing 425, a bearing pressure ring 427 can be fitted on the connection end to press the entire bearing 425 tightly.

[0102] In some embodiments of this application, such as Figure 4 , Figure 11 and Figure 12 As shown, the movable component 421 includes: a movable bracket 4211, a guide post 4212, and a connecting assembly 4213; The movable bracket 4211 is fitted between the base 423 and the curved cylinder 422, and is connected to the second lens 210 or the second mechanism 220 through the connecting component 4213; the movable bracket 4211 is provided with a mounting through hole 4214. The guide post 4212 is installed in the mounting through hole 4214. The first end of the guide post 4212 is movably inserted into the curved slide groove 4221, and the second end is movably inserted into the limiting waist hole 4231. When the curved cylinder 422 rotates, the first end of the guide post 4212 moves along the curved slide groove 4221, and the second end moves along the limiting waist hole 4231, driving the movable bracket 4211 and the connecting assembly 4213, as well as the second lens 210 or the second mechanism 220 to move along the optical axis direction.

[0103] In the embodiments of this application, the movable component 421 includes a movable bracket 4211 and a guide post 4212. During installation, the first movable bracket 4211 can be sleeved with the base 423 and the curved cylinder 422 first, and then the guide post 4212 can be inserted, making the movable component 421 simple in structure and easy to process and assemble.

[0104] Specifically, the number of guide posts 4212 corresponds to the number of mounting through holes 4214, curved slides 4221, and limiting waist holes 4231. There can be one or more of them to improve the stability of the internal transmission of the second focusing knob 410. Figure 12 In the embodiment shown, the number of mounting through holes 4214, limiting waist holes 4231 and curved grooves 4221 are all 3, and they are evenly distributed along the circumference and correspond one-to-one, so that each guide post 4212 can pass through the curved groove 4221, mounting through holes 4214 and limiting waist holes 4231 in sequence.

[0105] like Figure 12 As shown, the area on the movable bracket 4211 without the mounting through hole 4214 has a thickness in the axial direction that is less than the thickness of the area with the mounting through hole 4214, so as to reduce the weight of the movable bracket 4211 and thus reduce the overall weight of the second focusing mechanism 400.

[0106] In some embodiments of this application, such as Figure 4 As shown, the connecting assembly 4213 includes a second focusing bracket 4215 and a second connecting rod 4216 connected in sequence; the second focusing bracket 4215 passes through the fixed plate 11 and is connected to the movable bracket 4211, and the second connecting rod 4216 is connected to the second lens 210 or the second mechanism 220.

[0107] In the embodiments of this application, the first end of the second focusing bracket 4215 passes through the fixed plate 11, so that the fixed plate 11 can restrict the rotation of the second focusing bracket 4215 and the movable bracket 4211 around the focusing axis 700, thereby converting the rotation of the curved cylinder 422 into the axial movement of the movable bracket 4211, the second focusing bracket 4215 and the second connecting rod 4216, avoiding the second connecting rod 4216 from shaking due to the rotation being restricted only by the second lens 210 or the second mechanism 220, and thus avoiding affecting the focusing accuracy and the life of the second connecting rod 4216.

[0108] The trigger 520 can be mounted on the second focusing bracket 4215 or the second connecting rod 4216. Driven by either the second focusing bracket 4215 or the second connecting rod 4216, the trigger 520 moves relative to the sensor 510 along the optical axis. Figure 4 and Figure 9As shown, when the trigger 520 is a magnetic component, the second focusing bracket 4215 is provided with a second slot 4218 for fixing and installing the magnetic component. This application does not limit the specific structure of the second slot 4218, as long as it can accommodate the magnetic component.

[0109] like Figure 4 and Figure 9 As shown, the first connecting rod 322 and the second connecting rod 4216 are respectively located on both sides of the focusing shaft 700, and both are spaced apart from the focusing shaft 700, so that the first connecting rod 322 and the second connecting rod 4216 will not interfere with each other during the focusing process.

[0110] In some embodiments of this application, such as Figure 4 and Figure 9 As shown, the second transmission mechanism 420 includes: a second guide rod 424; the second guide rod 424 is arranged in a direction parallel to the optical axis and is fixedly connected to the housing 10; the second focusing bracket 4215 has a second guide hole 4217, and the second guide rod 424 passes through the second guide hole 4217.

[0111] In this embodiment, a second guide rod 424 fixedly connected to the housing 10 restricts the rotation of the second focusing bracket 4215 and guides its axial movement, ensuring that the second focusing bracket 4215 always moves axially. This results in higher focusing accuracy and stability for the second focusing mechanism 400 during focusing. Compared to the second transmission mechanism 420, which uses only a second connecting rod 4216 to connect to the second lens 210 or the second camera module 220 for rotational limiting, this embodiment avoids the second connecting rod 4216 from wobbling due to a tendency for the end connected to the second focusing bracket 4215 to rotate while the end connected to the second lens 210 or the second camera module 220 remains stationary. This reduces the risk of the second connecting rod 4216 wobbling and affecting focusing accuracy, thus extending its lifespan.

[0112] Since the distance between the first focusing bracket 321 of the first transmission mechanism 320 and the first lens assembly 100 is greater than the distance between the second focusing bracket 4215 of the second transmission mechanism 420 and the second lens assembly 200, the lengths of the first connecting rod 322 and the second connecting rod 4216 are different to ensure that the first lens assembly 100 and the second lens assembly 200 are aligned.

[0113] The structural shapes of the first connecting rod 322 and the second connecting rod 4216 can be set according to the positions of the first lens assembly 100, the second lens assembly 200, the first focusing bracket 321, and the second focusing bracket 4215. Both the first connecting rod 322 and the second connecting rod 4216 can be integrally formed rods, or they can be assembled from at least two rods. This application does not limit their structural shapes.

[0114] See Figure 13 and Figure 14 , Figure 13 for Figure 4 One of the exploded views of the binocular observation equipment shown; Figure 14 for Figure 4 The second exploded view of the binocular observation device is shown. The first connecting rod 322 includes a first ball-head connecting rod 3221, a first fixing rod 3222, and a first ball-head pressure plate 3223.

[0115] The first end of the first ball joint connecting rod 3221 is fixedly connected to the first focusing bracket 321, and the first end of the first fixing rod 3222 is fixedly connected to the first lens 110 or the first camera movement 120. The ball joint at the second end of the first ball joint connecting rod 3221 is rotatably disposed in the ball groove at the second end of the first fixing rod 3222. Through the cooperation between the ball joint and the ball groove, the first ball joint connecting rod 3221 can rotate freely relative to the first fixing rod 3222 when the first connecting rod 322 is installed, which can realize the adjustment of the posture of the first connecting rod 322 to adapt to the first lens assembly 100 in different positions.

[0116] After adjusting the posture, the ball head of the first ball head connecting rod 3221 is pressed into the ball groove of the first fixed rod 3222 by the first ball head pressure plate 3223, so as to fix the relative position of the first ball head connecting rod 3221 and the first fixed rod 3222, and avoid relative rotation of the first ball head connecting rod 3221 and the first fixed rod 3222 during focusing, which would affect the focusing accuracy.

[0117] The second connecting rod 4216 includes a second ball joint connecting rod 4216a, a second fixing rod 4216b, and a second ball joint pressure plate 4216c. The first end of the second ball joint connecting rod 4216a is fixedly connected to the second focusing bracket 4215, and the first end of the second fixing rod 4216b is fixedly connected to the second lens 210 or the second movement 220. The connection relationship between the second ball joint connecting rod 4216a, the second fixing rod 4216b, and the second ball joint pressure plate 4216c can be the same as that of the first connecting rod 322 described above, and will not be repeated here.

[0118] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application are included within the scope of protection of this application.
