Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of optical equipment, in particular to a binocular photo telescope. BACKGROUND

[0002] For binocular telescopes, due to the large volume of the binoculars, and in order to make the focusing structure more simple, the focusing structure is often arranged on the outside of the lens barrel corresponding to the objective lens module in the prior art, but this design is not convenient for the user to operate the focusing with one hand. For example, when the focusing structure is arranged on the outside of the right lens barrel, if the user holds the telescope with the left hand, the user needs to operate with the right hand when focusing is needed, and cannot achieve one-handed operation with the left hand, which is very inconvenient for the user in some use scenarios.

[0029] Please refer to Figure 1 and Figure 2 The binocular photoelectric telescope of the embodiment of the present application comprises a first lens barrel 11 and a second lens barrel 12 connected and arranged, one end of the first lens barrel 11 and the second lens barrel 12 respectively contains an ocular module 2 and a display screen module (not shown) in sequence, the other end of the first lens barrel 11 (or the second lens barrel 12) contains an objective module 5, a core module 6 and a main control module 7 in sequence, the core module 6 is arranged on the light path of the objective module 5; a magnification adjusting assembly 4 and a focusing structure 3 are arranged in sequence on the central axis shell 13 between the two lens barrels, the magnification adjusting assembly 4 is arranged on the side close to the ocular module 2 and is electrically connected with the main control module 7 and the display screen module respectively, and is used for adjusting the magnification of the image output by the display screen module; the focusing structure 3 is connected with the objective module 5 or the core module 6, and is used for adjusting the distance between the objective module 5 and the core module 6. The distance between the first lens barrel 11 and the second lens barrel 12 away from the central axis shell 13 and between the magnification adjusting assembly 4 and the focusing structure 3 is used to facilitate the user to operate the magnification adjusting assembly 4 and the focusing structure 3 with one hand. The focusing structure 3 and the magnification adjusting assembly 4 are arranged on the central axis shell 13 of the telescope, and the compact and reasonable arrangement of the assembly structure in the lens barrel reduces the size of the lens barrel, which facilitates the user to operate the focusing and the magnification adjustment with one hand, and makes the overall layout of the telescope more compact and reasonable. Whether the user uses the left hand or the right hand, the focusing and the magnification adjustment can be performed by one hand, which is very convenient to use. The center line at the maximum distance between the upper and lower surfaces of the central axis shell 13 is located on one side of the plane where the center line of the first lens barrel 11 and the center line of the second lens barrel 12 are located, that is, the surface on one side of the central axis shell 13 protrudes outward relative to the outer surface of the two lens barrels on this side, and the surface on the other side of the central axis shell 13 is recessed inward relative to the surface of the two lens barrels on this side, and the inward recessed side is convenient for the user to hold the telescope. The central axis shell 13 is not arranged in line with the two lens barrels, which shortens the total length between the first lens barrel 11, the central axis shell 13 and the second lens barrel 12, that is, the width size of the telescope, further reduces the size of the binocular photoelectric telescope, and facilitates the user to operate with one hand. The binocular photoelectric telescope of the embodiment is a single light single objective telescope, but in other embodiments, it can also be other types of telescopes, such as a double objective telescope.

[0030] Specifically, the two barrels refer to the first barrel 11 and the second barrel 12, that is, two barrel-shaped housings, and the middle shaft housing 13 is a housing connecting the two barrels, and the first barrel 11, the second barrel 12 and the middle shaft housing 13 together constitute the housing 1 of the binocular photoelectric telescope. The eyepiece module 2 and the display screen module are arranged in each of the two barrels. The eyepiece module 2 is arranged outside the display screen module, that is, close to the side of the human eye. When the human eye observes, the image displayed on the display screen module is observed through the eyepiece module 2. At least one of the barrels is provided with an objective lens module 5 and a movement module 6 and a main control module 7 matched with the objective lens module 5. The movement module 6 can be an infrared movement module, a low-light movement module, etc. The movement module 6 receives the image formed by the objective lens module 5 and transmits the image to the main control module 7, which transmits the processed image to the display screen module for display. The focusing structure 3 adjusts the distance between the objective lens module 5 and the movement module 6 to focus the objective lens module 5. To enhance the functionality of the binocular photoelectric telescope and make rational use of the internal space of the barrel, a distance measuring module 9 and a battery compartment module 10 can be arranged in the other barrel without the objective lens module 5. The distance measuring module 9 is used to measure the distance between the target object and the observer and display it on the display screen module, or it can be used to indicate the direction of the target object. The battery compartment module 10 is used to provide power for the binocular photoelectric telescope. The above-mentioned layout of the distance measuring module 9 and the battery compartment module 10 is only described in one specific embodiment. In other embodiments, both can be placed in the other barrel, or they can be placed in the two barrels respectively, and the specific layout position is not limited.

[0031] As shown in Figure 2 and Figure 3 , in order to facilitate the installation of the focusing structure 3 and the magnification adjustment assembly 4, a middle shell 8 can also be arranged in the middle shaft housing 13. The middle shell 8 is fixedly connected with the middle shaft housing 13 and includes a first accommodating cavity 81, a connecting cavity 82 and a second accommodating cavity 83 arranged in sequence. The first accommodating cavity 81 is arranged away from the eyepiece module 2, the focusing structure 3 is at least partially located in the first accommodating cavity 81, and the magnification adjustment assembly 4 is at least partially located in the second accommodating cavity 83. The arrangement of the middle shell 8 not only facilitates the installation of the focusing structure 3 and the magnification adjustment assembly 4, but also protects them to a certain extent. During assembly of the telescope, the focusing structure 3 and the magnification adjustment assembly 4 can be installed in the middle shell 8 respectively, and then the middle shell 8 is fixedly connected with the middle shaft housing.

[0032] Specifically, as shown in Figure 4 and Figure 5As shown, in this embodiment, the focusing structure 3 includes a focusing knob assembly 31, a first guide rod 37, a connecting assembly 36, and a connecting rod 34. The focusing knob assembly 31 is disposed within the first receiving cavity 81 and is used to drive the connecting rod 34 to move towards or away from the eyepiece module 2. One end of the first guide rod 37 is movably connected to the connecting assembly 36, and the connecting assembly 36 is fixedly connected to one end of the connecting rod 34. The movable connection between the first guide rod 37 and the connecting assembly 36 can prevent jamming during focusing, making focusing smoother.

[0033] Specifically, such as Figure 5 and Figure 6 As shown, in this embodiment, the connecting assembly 36 includes a pressure block 361 and a pressure plate 362. The pressure block 361 has a receiving cavity, and the pressure plate 362 has a through hole. The first guide rod 37 has a first protrusion 371 at one end near the eyepiece module 2 and a second protrusion 372 at the other end away from the eyepiece module 2. The first protrusion 371 is inserted into the receiving cavity, and the rod of the first guide rod 37 is inserted into the through hole of the pressure plate 362. The pressure block 361 and the pressure plate 362 are fixedly connected, sealing the first protrusion 371 within the receiving cavity of the pressure block 361, thus movably connecting the first guide rod 37 and the connecting assembly 36. The surface of the pressure block 361 near the eyepiece module 2 is fixedly connected to the connecting rod 34. To make the focusing structure 3 more stable and smooth, the first protrusion 371 and the connecting component 36 can be fitted with a clearance, and the axial clearance between the first protrusion 371 and the connecting component 36 along the first guide rod 37 can be no greater than 0.05mm. This clearance setting is reasonable and can improve the backlash accuracy of the focusing knob. To further improve the smoothness of focusing, the surface of the first protrusion 371 away from the pressure plate 362 can be set as an outwardly convex spherical surface. The end of the first guide rod 37 away from the eyepiece module 2 is movably connected to the lens of the movement module 6 or the objective lens module 5 through the second protrusion 372. At this time, the lens can be, for example, the lens closest to the eyepiece module 2 in the objective lens module 5.

[0034] The focusing knob assembly 31 comprises a focusing hand wheel 311, a support 312 and a second guide rod 313. The focusing hand wheel 311 is arranged in the first accommodating cavity 81, the second guide rod 313 is arranged in the focusing hand wheel 311 and fixedly connected with the focusing hand wheel 311, the support 312 is arranged on the side of the focusing hand wheel 311 close to the eyepiece module 2, located in the connecting cavity 82 and fixedly connected with the middle shell 8 through the fixing ring 32, the fixing ring 32 is arranged in the connecting cavity 82 and the support 312 is arranged in the fixing ring 32. One end of the second guide rod 313 is inserted into the center hole of the support 312, and the other end is threadedly connected with the connecting rod 34. The other end of the second guide rod 313 passes out of the first accommodating cavity 81 and is fixedly arranged with a limiting adapter block 315 on the surface of the middle shell 8 away from the eyepiece module 2, the limiting adapter block 315 is fixedly arranged with a supporting block 314, the supporting block 314 is arranged with a groove, the second guide rod 313 is arranged in the groove, and the support 312 and the supporting block 314 support the second guide rod 313, so that the focusing knob assembly 31 can rotate under the support of the two. The connecting rod 34 comprises a first head 341, a rod 343 and a second head 342 which are sequentially connected, the first head 341 is arranged with an internal thread, the internal thread is engaged with the external thread of the second guide rod 313, the thread cooperation play is not greater than 0.03mm, and the thread head number and lead should meet the front and rear focusing allowance requirements of the objective module 5. The connecting rod 34 is arranged outside the middle shell 8, the surface of the middle shell 8 close to the connecting rod 34 is arranged with a guide groove 84, and the rod 343 is located in the guide groove 84, so that when the focusing hand wheel 311 rotates, the connecting rod 34 is driven by the second guide rod 313 to make reciprocating linear motion towards the direction close to or away from the eyepiece module 2. When the focusing hand wheel 311 is rotated, the focusing hand wheel 311 drives the second guide rod 313 fixedly connected therewith to rotate together, when the second guide rod 313 rotates, the rotation of the connecting rod 34 threadedly connected therewith is limited by the guide groove 84, therefore, the connecting rod 34 can only move linearly towards the direction close to or away from the eyepiece module 2, thereby driving the first guide rod 37 to move linearly, and finally realizing the focusing function.

[0035] As Figure 2 And Figure 4As shown, the objective module 5 includes a fixedly connected first objective module and a second objective module, which can be fixedly connected by, for example, a threaded fit. The first objective module is arranged close to the core module 6; the binocular photoelectric telescope also includes an objective guiding cylinder 33, which is arranged on the first objective module and is fixedly connected with the core module 6 and the driving end of the focusing structure 3. The purpose of splitting the objective module 5 into two components (the first objective module and the second objective module) is to facilitate installation. The objective guiding cylinder 33 is arranged to facilitate movement of the core module 6, making the focusing more stable and reliable. The objective guiding cylinder 33 is in clearance fit with the first objective module, and a guiding limiting structure is arranged between the objective guiding cylinder 33 and the first objective module, which can be, for example, a positioning pin and a guiding groove 84 used in cooperation. For example, a sliding groove is arranged on the first objective module, and a positioning pin is correspondingly arranged on the objective guiding cylinder 33. The height of the objective guiding cylinder 33 can be appropriately increased, and the length of the positioning pin is increased accordingly, so that the cooperation length of the positioning pin and the sliding groove is increased, and the guiding of the guiding limiting structure is more stable and reliable. The objective guiding cylinder 33 is used to move in the direction defined by the guiding limiting structure towards or away from the first objective module.

[0036] As shown in Figure 4 and Figure 6 For example, a limiting block 35 can be arranged, and a protruding connecting lug 331 is arranged on the objective guiding cylinder 33, and an open slot is formed in the connecting lug 331, and the radial dimension of the open slot is not less than the radial dimension of the middle shaft of the first guiding rod 37. A limiting blind hole is arranged on the limiting block 35, and the diameter of the limiting blind hole is greater than the radial dimension of the second protruding block 372 of the first guiding rod 37, and the second protruding block 372 is located in the limiting blind hole, the shaft of the first guiding rod 37 is arranged in the open slot, and the limiting block 35 is fixedly connected with the connecting lug 331, so that the first guiding rod 37 and the objective guiding cylinder 33 are movably connected, that is, the first guiding rod 37 and the core module 6 are movably connected.

[0037] As shown in Figure 5As shown, the magnification adjusting assembly 4 comprises a magnification adjusting hand wheel 41 and an encoder 44, the encoder 44 is fixed on the middle shaft shell 13, and the encoder 44 is arranged close to the objective lens module 5 direction on the side of the rotating knob. The encoder 44 is inverted to facilitate the cooperation and installation of the magnification adjusting assembly 4, and the circuit cooperation is also facilitated. The magnification adjusting hand wheel 41 is arranged in the second accommodating cavity 83, and the magnification adjusting hand wheel 41 is used to drive the rotating knob to rotate together when the magnification adjusting hand wheel 41 rotates. The magnification adjusting hand wheel 41 can be fixedly connected with the rotating knob of the encoder 44 or form a clamping, limiting connection, etc., as long as the rotating knob can be driven to rotate simultaneously when the magnification adjusting hand wheel 41 is rotated. In order to facilitate the installation of the encoder 44 and make the installation stable, an encoder support 43 can also be arranged between the magnification adjusting hand wheel 41 and the encoder 44, and the encoder support 43 is arranged in the through hole of the middle shell 8 close to the eyepiece module 2 end. The rotating knob of the encoder 44 passes through the encoder support 43 and is connected with the magnification adjusting hand wheel 41. When the magnification adjusting hand wheel 41 rotates, the encoder support 43 and the rotating knob are driven to rotate together.

[0038] The rotating magnification adjusting hand wheel 41 can realize manual focusing. In order to realize various flexible focusing modes, an electronic focusing mode can also be adopted. For example, Figure 2 As shown, for example, the adjusting button 42 can be arranged on the two sides of the magnification adjusting hand wheel 41 of the middle shaft shell 13, the adjusting button 42 is electrically connected with the main control module 7, and when the adjusting button 42 is pressed, the adjusting button 42 transmits the adjusting signal to the main control module 7, and the main control module 7 controls the rotating knob of the encoder 44 to rotate, thereby realizing automatic focusing. Of course, the switch button and the menu button can also be arranged on the two sides of the magnification adjusting hand wheel 41, which is also convenient to operate. The magnification adjusting assembly 4 and the focusing structure 3 are arranged between the two lens barrels, which is convenient for users to operate, and makes the overall structure of the telescope more compact and reasonable.

[0039] As shown, Figure 4 and Figure 5As shown, in order to improve the waterproof effect of the telescope, some sealing members 100 can also be arranged, for example, a first sealing ring 101 can be arranged between the objective lens module 5 and the corresponding lens barrel; specifically, the first sealing ring 101 is arranged on the outer wall of the objective lens module 5, and the objective lens module 5 is in interference fit with the corresponding lens barrel through the first sealing ring 101, so as to realize the waterproof between the objective lens module 5 and the housing 1. The second sealing ring 102 is arranged in the focusing knob assembly 31, for example, the second sealing ring 102 can be arranged between the second guide rod 313 and the focusing hand wheel 311; specifically, the second sealing ring 102 is arranged on the outer wall of the second guide rod 313, and the second guide rod 313 is in interference fit with the focusing hand wheel 311 through the second sealing ring 102, so as to realize the waterproof of the focusing knob assembly 31.
