[0030] Technical effects and advantages of the present invention:

[0031] (1) The present invention utilizes the setting of the stopper mechanism. When the periscope camera body is not needed to work, the stopper block will clamp the first fixing plate, so that the pressing member is only slightly exposed on the back of the side plate. At this time, the key function of the pressing member can be normally used by lightly pressing. When the camera assembly is needed to work, the stopper block moves in the connecting groove and is completely retracted into the connecting groove, so that the pressing member can move and expose more length until the prism is completely exposed and can work. This structural setting can hide the camera when it is not in use, thereby improving the protection effect of the camera. It also makes the pressing member exposed shorter when used as a button, which is more convenient to use.

[0032] (2) The present invention utilizes the setting of the friction mechanism. When the extrusion block moves, it drives the extrusion plate to move, until the extrusion plate squeezes the fixed ring and drives the fixed rod to move. The movement of the fixed rod drives the piston block to move. The movement of the piston block compresses the air in the first connecting groove, so that the rubber sheet bulges and presses against the outer wall of the stop block, thereby increasing the friction force on the stop block retracted into the connecting groove, thereby prolonging the time for the stop block to reset, thereby preventing the stop block from extending quickly and affecting the movement of the first fixed plate.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Embodiment 1

[0049] The present invention provides Figures 1 to 6The periscope camera structure shown in the figure includes a bottom plate 101, a camera assembly, a stop mechanism, an elastic mechanism and an adjustment mechanism. The top of the bottom plate 101 is fixedly connected to a side plate 102. The front of the side plate 102 is provided with a pressing groove 103. The inner wall of the pressing groove 103 is movably connected with a pressing piece 104. The camera assembly is arranged inside the pressing piece 104. The camera assembly includes a periscope camera body 301. The periscope camera body 301 is installed inside the pressing piece 104. A prism 302 is installed inside the pressing piece 104. The top of the pressing piece 104 and located above the prism 302 is provided There is a protective sheet 303, and a cover plate 304 is arranged at the top of the pressing piece 104 and above the periscope camera body 301. The prism 302 can be protected by the protective sheet 303. At the same time, the setting of the prism 302 allows the periscope camera body 301 to shoot the picture above the prism 302. At the same time, the cover plate 304 is fixed to the top of the pressing piece 104 in a non-protruding shape by means of bolts on the ear plate, thereby clamping the periscope camera body 301 inside the pressing piece 104, so that the periscope camera body 301 can be used stably without affecting the movement of the pressing piece 104.

[0050] In a preferred embodiment, the stop mechanism is arranged between the bottom plate 101 and the pressing piece 104, and the stop mechanism includes a fixed block 201, which is symmetrically fixedly connected to the top of the bottom plate 101, and the outer wall of the fixed block 201 is provided with a connecting groove 202, and the inner wall of the connecting groove 202 is slidably connected with a stop block 203, and one side of the stop block 203 is provided with a first inclined surface 204, and the elastic mechanism is arranged between the pressing piece 104 and the fixed block 201, and the adjustment mechanism is arranged between the first fixed plate 401 and the stop block 203. When the periscope camera body 301 is not required to work, the stop block 203 will jam the first fixed plate 401. The fixed plate 401 makes the pressing piece 104 only slightly exposed on the back side of the side plate 102. At this time, the button function of the pressing piece 104 can be used normally by lightly pressing. When the camera assembly needs to work, the stop block 203 moves in the connecting groove 202 and is completely retracted into the connecting groove 202, so that the pressing piece 104 can be moved and exposed more length until the prism 302 is completely exposed to work. This structural setting can hide the camera when it is not in use, thereby improving the protection effect of the camera. It also makes the pressing piece 104 have a shorter exposed length when used as a button, which is more convenient to use.

[0051] The elastic mechanism includes a first spring 403, an outer wall of the pressing member 104 is fixedly connected to a first fixing plate 401, an outer wall of the fixing block 201 is fixedly connected to a second fixing plate 402, the first spring 403 is arranged between the first fixing plate 401 and the second fixing plate 402, a connecting rod 405 is fixedly connected to the front of the first fixing plate 401, a connecting sleeve 404 is fixedly connected to the back of the second fixing plate 402, an outer wall of the connecting rod 405 is movably connected to the inner wall of the connecting sleeve 404, and the first spring 403 is arranged between the first fixing plate 401 and the second fixing plate 402. 03 is sleeved on the outer wall of the connecting sleeve 404, through the elastic action of the first spring 403, and the second fixing plate 402 will position the first spring 403, so that the first spring 403 always presses the first fixing plate 401, so that the pressing piece 104 always has a tendency to move toward the side plate 102, and through the setting of the connecting sleeve 404 and the connecting rod 405, the first spring 403 will not be laterally deformed when compressed, thereby improving the stability of the first spring 403 when used.

[0052] Among them, the adjustment mechanism includes a slide plate 502, the outer wall of the fixed block 201 is provided with a groove 501, the outer wall of the slide plate 502 is slidably connected to the inner wall of the groove 501, the inner wall of the groove 501 is provided with a first movable groove 503, the back side of the groove 501 is fixedly connected with a first rack 505, the first rack 505 is inserted into the inside of the first movable groove 503, the inner wall of the first movable groove 503 is rotatably connected with a connecting gear 506, the outer wall of the first rack 505 is meshed with the outer wall of the connecting gear 506, the inside of the first movable groove 503 is inserted with a second rack 507, and the outer wall of the second rack 507 is meshed with the outer wall of the connecting gear 506.

[0053] An extrusion mechanism is arranged between the second rack 507 and the stop block 203, and the extrusion mechanism includes an extrusion block 508. The inner wall of the first movable groove 503 is provided with a second movable groove 504, and the interior of the second movable groove 504 is connected with the interior of the connecting groove 202. The outer wall of the extrusion block 508 is slidably connected with the inner wall of the second movable groove 504, the front side of the extrusion block 508 is fixedly connected with the back side of the second rack 507, and the back side of the extrusion block 508 is provided with a second inclined surface 509. The front side of the stop block 203 is provided with a slot 510, and the inner wall of the slot 510 is provided with a third inclined surface 511. A second spring 512 is fixedly connected between the stop block 203 and the inner wall of the connecting groove 202, and a friction mechanism is arranged on the front side of the stop block 203.

[0054] The pressing member 104 is pressed hard. At this time, the moving distance of the pressing member 104 becomes longer, so that after the second button contact 704 contacts the first button contact 703, the pressing member 104 continues to move and drives the slide plate 502 to move. The movement of the slide plate 502 drives the first rack 505 to move. The movement of the first rack 505 drives the meshing connecting gear 506 to rotate. The rotating connecting gear 506 drives the meshing second rack 507 to move. The movement of the second rack 507 drives the extrusion block 508 to move. The extrusion block 508 moves and is inserted into the slot 510 until the second inclined surface 509 contacts the third inclined surface 511. At this time, the extrusion block 508 continues to move, so that the second inclined surface 509 squeezes the third inclined surface 511. At this time, the stop block 203 can be moved and retracted into the connecting groove 202. At the same time, the second spring 512 is compressed until the stop block 203 is completely retracted into the connecting groove 202.

[0055] Among them, the friction mechanism includes a rubber sheet 602, a first connecting groove 601 is opened on the inner wall of the connecting groove 202, the rubber sheet 602 is fixedly connected to the side of the inner wall of the first connecting groove 601, the inner wall of the first connecting groove 601 is slidably connected with a piston block 603, and a connecting mechanism is arranged between the piston block 603 and the extrusion block 508.

[0056] The connecting mechanism includes an extrusion plate 605, a second connecting groove 604 is opened between the first connecting groove 601 and the second movable groove 504, the outer wall of the extrusion plate 605 is slidably connected to the inner wall of the second connecting groove 604, one side of the extrusion plate 605 is fixedly connected to one side of the extrusion block 508, a fixing rod 606 is fixedly connected to the front of the piston block 603, a connecting hole 608 is opened on the front of the extrusion plate 605, the outer wall of the fixing rod 606 is movably connected to the inner wall of the connecting hole 608, and a fixing ring 607 is fixedly sleeved on the outer wall of the fixing rod 606.

[0057] When the extrusion block 508 moves, it drives the extrusion plate 605 to move until the extrusion plate 605 squeezes the fixing ring 607 and drives the fixing rod 606 to move. The movement of the fixing rod 606 drives the piston block 603 to move. The movement of the piston block 603 compresses the air in the first connecting groove 601, so that the rubber sheet 602 bulges and presses against the outer wall of the stop block 203, thereby increasing the friction force on the stop block 203 retracted into the connecting groove 202, which can prolong the time it takes to reset the stop block 203, thereby preventing the stop block 203 from extending quickly and affecting the movement of the first fixed plate 401.

[0058] Among them, the inner wall of the groove 501 is fixedly connected to the limit rod 514, the front of the slide plate 502 is provided with a limit hole 515, the outer wall of the limit rod 514 and the inner wall of the limit hole 515 are movably connected, and the front of the slide plate 502 is provided with a third spring 513, and the third spring 513 is sleeved on the outer wall of the limit rod 514. Through the elastic action of the third spring 513, the slide plate 502 always has a tendency to move toward the pressing member 104, so that the slide plate 502 can also be automatically reset, but the friction force encountered by the slide plate 502 when moving is relatively large, which makes the reset time of the slide plate 502 longer.

[0059] Among them, a control board 701 is arranged at the top of the bottom plate 101, a second soft circuit board 705 is arranged between the control board 701 and the periscope camera body 301, a second button contact 704 is arranged on the front of the pressing piece 104, a first button contact 703 is arranged on the back of the slide plate 502, and a first soft circuit board 702 is arranged between the control board 701 and the first button contact 703. The working signal of the button of the pressing piece 104 contacts the first button contact 703 through the second button contact 704, and then transmits the signal to the control board 701 through the first soft circuit board 702, and the working signal of the periscope camera body 301 is transmitted to the control board 701 through the second soft circuit board 705.

[0060] Embodiment 2

[0061] The embodiment of the present invention also provides a method for using a periscope camera structure, comprising the following steps:

[0062] Step 1: lightly press the pressing member 104, the pressing member 104 moves in the pressing groove 103, the movement of the pressing member 104 drives the first fixing plate 401 to move, the movement of the first fixing plate 401 compresses the first spring 403, the movement of the pressing member 104 drives the second key contact 704 to move at the same time, until the second key contact 704 contacts the first key contact 703, and then the signal is transmitted to the control board 701 through the first flexible circuit board 702, and the pressing member 104 is released, and the pressing member 104 can be moved in the reverse direction under the elastic action of the first spring 403, until the first fixing plate 401 abuts against the stop block 203 to complete the reset;

[0063] Step 2: Press the pressing member 104 again. At this time, the moving distance of the pressing member 104 becomes longer, so that after the second key contact 704 contacts the first key contact 703, the pressing member 104 continues to move and drives the slide plate 502 to move. The movement of the slide plate 502 drives the first rack 505 to move. The movement of the first rack 505 drives the meshing connecting gear 506 to rotate. The rotating connecting gear 506 drives the meshing second rack 507 to move. The movement of the second rack 507 drives the extrusion block 508 to move. The extrusion block 508 moves and is inserted into the slot 510 until the second inclined surface 509 contacts the third inclined surface 511. At this time, the extrusion block 508 continues to move, so that the second inclined surface 509 squeezes the third inclined surface 511, and the stop block 203 can be moved and retracted into the connecting groove 202, and the second spring 512 is compressed until the stop block 203 is completely retracted into the connecting groove 202. The extrusion block 508 moves and drives the extrusion plate 605 to move, until the extrusion plate 605 squeezes the fixing ring 607 and drives the fixing rod 606 to move, and the movement of the fixing rod 606 drives the piston block 603 to move. The movement of the piston block 603 compresses the air in the first connecting groove 601, so that the rubber sheet 602 bulges and presses against the outer wall of the stop block 203;

[0064] Step three: release the pressing piece 104. At this time, under the elastic action of the first spring 403, the first fixed plate 401 drives the pressing piece 104 to quickly reset. At this time, since the stop block 203 is subjected to a large friction force in the connecting groove 202, the moving first fixed plate 401 can quickly pass over the stop block 203, thereby increasing the extended length of the pressing piece 104 until the prism 302 is completely exposed on the back of the side plate 102, and the periscope camera body 301 can be used. After use, press the pressing piece 104 lightly to move the pressing piece 104 until the first fixed plate 401 squeezes the first inclined surface 204, so that the stop block 203 moves into the connecting groove 202 until the first fixed plate 401 passes over the stop block 203. At this time, under the elastic action of the second spring 512, the stop block 203 pops out of the connecting groove 202 and jams the first fixed plate 401, completing the reset of the pressing piece 104.

[0065] Embodiment 3

[0066] An embodiment of the present invention provides a method for preparing a periscope camera structure, which comprises the following steps:

[0067] S1, prepare the bottom plate 101 and fix the side plate 102 on the top thereof, and open a pressing groove 103 on the front of the side plate 102;

[0068] In one embodiment, the bottom plate 101 can be made of aviation-grade aluminum alloy (7075-T6) material with a thickness of 2 mm, formed by CNC precision machining, and has a size of 100 mm × 60 mm. The side panels are made of the same material, with a thickness of 1.5 mm, a height of 30 mm, and a width of 60 mm. In order to reduce the internal reflectivity, the bottom plate and the side panels are subjected to special surface treatment after the processing is completed. First, the parts are carefully cleaned and dried, and then an automatic high-precision micro-mobile printing device is used to reciprocate printing with ultra-black ink. Immediately after printing, UV light is irradiated at close range for several seconds to harden the ink. This treatment method can reduce the reflectivity of the blackened area to less than 0.3%, which is significantly better than the traditional electrophoresis process and effectively improves the light pollution problem inside the camera. After the treatment is completed, the surfaces of both are anodized again, and the thickness of the oxide layer is 15 μm. Use M2 screws to fix the side panels to the top of the bottom plate, and the tightening torque is 0.4N·m. A pressing groove 103 is precisely opened on the front side of the side plate, with a size of 40mm×20mm and a depth of 10mm.

[0069] S2, preparing the pressing member 104 and movably inserting and connecting it to the inner wall of the pressing groove 103;

[0070] In one embodiment, the pressing piece 104 can be, but is not limited to, made of polycarbonate (PC) material through an injection molding process, with a size of 38mm×18mm×28mm, which is slightly smaller than the pressing groove 103 to ensure free movement. Before injection molding, the mold is specially treated, and the same ultra-black ink printing and UV curing process as the bottom plate and side plate are used to ensure that the inner surface of the pressing piece after injection molding also has extremely low reflectivity. During injection molding, the mold temperature is maintained at 80°C and the injection pressure is 80MPa. A 5μm thick anti-fingerprint coating is sprayed on the surface of the molded pressing piece to improve the user experience.

[0071] S3, installing a camera assembly inside the pressing member 104;

[0072] In one embodiment, a 1 / 2.8-inch CMOS sensor with a periscope camera body of 12 million pixels is selected. The prism is made of K9 optical glass with a side length of 15 mm. In order to further reduce internal reflections, the non-optical functional surface of the prism is also treated with ultra-black. The protective sheet is made of 0.3 mm thick sapphire glass, and the cover plate is made of 0.5 mm thick titanium alloy. All internal components undergo the above-mentioned ultra-black treatment before installation to minimize internal reflections. Install these components in turn into the inside of the pressing piece 104, fix them with UV curing glue, and the curing time is 30 seconds to ensure that the components are stable and do not affect the movement of the pressing piece 104.

[0073] Subsequent steps S4-S9 may all use the same ultra-black processing process when it comes to internal components.

[0074] S4, setting a stop mechanism between the bottom plate 101 and the pressing member 104, specifically comprising: symmetrically fixing a fixing block 201 on the top of the bottom plate 101; opening a connecting groove 202 on the outer wall of the fixing block 201; preparing a stop block 203, opening a first inclined surface 204 on one side thereof, and slidingly connecting the stop block 203 to the inner wall of the connecting groove 202;

[0075] In one embodiment, two fixed blocks 201 made of 304 stainless steel are symmetrically fixed on the top of the bottom plate 101, with dimensions of 20mm×10mm×5mm. A connecting groove 202 with dimensions of 15mm×8mm×4mm is provided on the outer wall of each fixed block 201. The stop block 203 is made of titanium alloy Ti-6Al-4V material, with dimensions of 14mm×7mm×3.5mm, and a first inclined surface 204 with a 45° angle is provided on one side. The stop block 203 is slidably connected to the inner wall of the connecting groove 202 to ensure that it can move smoothly.

[0076] S5. An elastic mechanism is provided between the pressing member 104 and the fixing block 201;

[0077] In one embodiment, SUS304 stainless steel wire is used to make the first spring, with a wire diameter of 0.5 mm, an outer diameter of 5 mm, a free length of 20 mm, and a spring stiffness of 0.5 N / mm. The spring is installed between the pressing member 104 and the fixing block 201 to ensure that the pressing member 104 has an appropriate resilience while not affecting its smooth movement in the pressing groove.

[0078] S6. An adjustment mechanism is provided between the first fixing plate 401 and the stop block 203 .

[0079] In one embodiment, the adjustment mechanism includes a slide plate 502, a first rack 505, a connecting gear 506, a second rack 507 and an extrusion block 508, and these components work together to achieve precise adjustment. The slide plate 502 is made of polytetrafluoroethylene (PTFE) material, has a size of 25mm×15mm×2mm, has good self-lubricating properties, is installed in the slot 501 provided on the outer wall of the fixed block 201, and can slide along the slot 501. The first rack 505 is fixed to the back of the slot 501 and is linked to the movement of the slide plate 502. The connecting gear 506 is installed in the first movable groove 503 and meshes with the first rack 505 and the second rack 507. All racks and gears use a module of 0.5, the connecting gear 506 has a diameter of 10mm and 20 teeth. The second rack 507 is made of POM engineering plastic, installed in the first movable groove 503, and can move under the drive of the gear. The extrusion block 508 is made of polyetheretherketone (PEEK) material and is connected to the second rack 507 for transmitting force and motion. When the pressing piece 104 is pressed, it drives the slide 502 to move, and then drives the extrusion block 508 through the gear transmission system, and finally acts on the stop block 203 to achieve the adjustment function. This design ensures the accuracy and durability of the adjustment mechanism while providing a smooth operating experience. Through the above preparation method and parameter selection, a compact and reliable periscope camera structure can be produced.

[0080] The embodiment of the present invention provides a periscope camera structural component with a reflectivity of less than 0.3% and a preparation method thereof. The method adopts an innovative ultra-black treatment process to significantly reduce the reflectivity inside the structural component. Specifically, when preparing key components such as the bottom plate 101, the side plate 102 and the pressing piece 104, they are first finely cleaned and dried. Subsequently, an automatic high-precision micro-mobile printing device is used to perform reciprocating printing using ultra-black ink. After printing is completed, UV light is immediately irradiated at close range for several seconds to harden the ink. This treatment method is not only applicable to metal parts, but can also be applied to the inside of injection molds to ensure that the inner surface of the injection molded part also has an extremely low reflectivity.

[0081] Through this ultra-black treatment process, the periscope camera structure of the present invention reduces the internal reflectivity to below 0.3% while maintaining the original functions and performance. This improvement greatly reduces internal light pollution and improves imaging quality, especially in low-light environments. Compared with the traditional electrophoresis process, this process not only achieves a lower reflectivity, but also has higher durability and stability. In practical applications, this ultra-black treatment is applied to all surfaces that may produce reflections, such as the bottom plate, side plates, inside of the pressing piece, and the non-optical functional surfaces of the prism, thereby minimizing internal reflections.

[0082] In order to verify the effect and durability of the ultra-black treatment, the present invention also adds a series of special tests. This includes using an integrating sphere and a spectrophotometer to test the reflectivity of each internal surface after treatment to ensure that the reflectivity is below 0.3%; a standard wear test on the surface after ultra-black treatment to ensure that there will be no significant increase in reflectivity during long-term use; a thermal cycle test to place the entire assembly in a temperature cycle from -40°C to 85°C to test the adhesion and stability of the ultra-black coating; finally, an imaging quality comparison test was also conducted to compare the treated periscope camera with the untreated control group, especially in low-light environments, to evaluate the effect of ultra-black treatment on image quality.

[0083] Through these optimizations and additional testing, the periscope camera structure of the present invention not only maintains the original function and reliability, but also achieves significant improvements in optical performance. The realization of ultra-low reflectivity effectively solves the problem of internal light pollution and greatly improves the image quality, especially in complex light environments.

[0084] In some embodiments, the installation of the camera assembly in step S3 includes: installing the periscope camera body 301 inside the pressing piece 104; installing the prism 302 inside the pressing piece 104; setting a protective sheet 303 at the top of the pressing piece 104 and above the prism 302; and setting a cover plate 304 at the top of the pressing piece 104 and above the periscope camera body 301.

[0085] Specifically, the installation of the camera assembly in step S3 includes the following detailed steps:

[0086] S31: Install the periscope camera body 301 inside the pressing member 104.

[0087] This step uses a 1 / 2.8-inch CMOS sensor with a periscope camera body 301 of 12 million pixels. First, reserve a mounting groove of 12mm×12mm×6mm inside the pressing piece 104. Use a precision positioning tool to place the periscope camera body 301 in the mounting groove, ensuring that its optical axis is aligned with the center line of the pressing piece 104. Use epoxy resin glue (such as 3M DP460) to fix the periscope camera body 301. The curing time is 24 hours, and the curing temperature is maintained at 25°C.

[0088] S32 : installing the prism 302 inside the pressing member 104 .

[0089] In this step, the prism 302 is made of K9 optical glass with a side length of 15mm and a surface coated with an anti-reflection film, and the transmittance reaches 99.5%. Inside the pressing piece 104, 10mm in front of the periscope camera body 301, a 15.5mm×15.5mm×15.5mm installation position is reserved. Use a vacuum suction pen to accurately place the prism 302 at this position to ensure that its 45° reflective surface is at a 45° angle to the optical axis of the camera. Use UV curing glue (such as DYMAX 9-20557) to fix the prism 302. The curing time is 30 seconds. Use a UV light source with a wavelength of 365nm and a light intensity of 100mW / cm 2 .

[0090] S33 : a protection sheet 303 is disposed at the top of the pressing member 104 and above the prism 302 .

[0091] The protective sheet 303 is made of 0.3mm thick sapphire glass with a size of 16mm×16mm. First, a 16.2mm×16.2mm and 0.4mm deep groove is opened on the top of the pressing piece 104. Using clean gloves, place the protective sheet 303 into the groove. Use optical grade transparent glue (such as LOCTITE AA 3491) to apply a circle of 0.5mm wide glue line around the edge of the protective sheet 303 to ensure that it does not block the effective light path. Use a UV light source with a wavelength of 365nm to cure for 60 seconds, with a light intensity of 50mW / cm 2 .

[0092] S34: A cover plate 304 is arranged at the top of the pressing member 104 and above the periscope camera body 301 .

[0093] The cover plate 304 is made of 0.5mm thick titanium alloy (Ti-6Al-4V) material and has a size of 20mm×15mm. At the top of the pressing piece 104, just above the periscope camera body 301, a 20.2mm×15.2mm, 0.6mm deep mounting groove is milled out. Place the cover plate 304 into the mounting groove and fix it at the four corners with M1.2 self-tapping screws with a tightening torque of 0.15N·m. At the edge where the cover plate 304 contacts the pressing piece 104, a silicone rubber sealant is used for sealing to prevent dust and moisture from entering.

[0094] Through the above detailed installation steps and process parameters, it can be ensured that the camera assembly is accurately and firmly installed inside the pressing member 104, while ensuring the optical performance and overall sealing.

[0095] In some embodiments, step S5 includes: fixing the first fixing plate 401 to the outer wall of the pressing member 104; fixing the second fixing plate 402 to the outer wall of the fixing block 201; setting a first spring 403 between the first fixing plate 401 and the second fixing plate 402; fixing the connecting rod 405 to the front side of the first fixing plate 401; fixing the connecting sleeve 404 to the back side of the second fixing plate 402; making the outer wall of the connecting rod 405 movably interlaced with the inner wall of the connecting sleeve 404; and sleeve the first spring 403 on the outer wall of the connecting sleeve 404.

[0096] Specifically, the detailed implementation process of step S5 is as follows:

[0097] S51 : The first fixing plate 401 is fixedly connected to the outer wall of the pressing member 104 .

[0098] The first fixing plate 401 is made of 7075-T6 aluminum alloy material with a size of 30mm×20mm×2mm. Two M3 threaded holes are pre-processed on the outer wall of the pressing piece 104 with a spacing of 20mm. Use two M3×8mm hexagon socket screws to fix the first fixing plate 401 on the pressing piece 104 with a tightening torque of 1.2N·m. To enhance the connection strength, apply medium-strength thread locking agent on the contact surface between the screw and the first fixing plate 401, and the curing time is 24 hours.

[0099] S52 : The second fixing plate 402 is fixedly connected to the outer wall of the fixing block 201 .

[0100] The second fixing plate 402 is also made of 7075-T6 aluminum alloy, with a size of 35mm×25mm×2mm. A groove of 35.2mm×25.2mm×0.5mm is pre-milled on the outer wall of the fixing block 201. The second fixing plate 402 is bonded in the groove using epoxy resin structural adhesive (e.g. 3M DP460), with a curing temperature of 60°C and a curing time of 4 hours. To further enhance the connection strength, spot weld 4 points around the edges of the second fixing plate 402, with a welding current of 80A and a time of 0.2 seconds.

[0101] S53 : a first spring 403 is arranged between the first fixing plate 401 and the second fixing plate 402 .

[0102] This step uses a compression spring made of SUS304 stainless steel, with a wire diameter of 1mm, an outer diameter of 12mm, a free length of 40mm, and a spring stiffness of about 0.8N / mm. A positioning groove with a diameter of 12.2mm and a depth of 1mm is processed on each of the first fixing plate 401 and the second fixing plate 402 to place the spring end.

An M6 internal thread with a depth of 8mm is turned at the center of the front of the first fixed plate 401. One end of the connecting rod 405 is processed into an M6 external thread with a length of 10mm. Use a torque wrench to screw the connecting rod 405 into the first fixed plate 401, with a tightening torque of 4N·m. Apply medium-strength anaerobic glue to the threaded connection, and the curing time is 24 hours.

[0105] S55 : Fixing the connecting sleeve 404 on the back side of the second fixing plate 402 .

[0106] The connecting sleeve 404 is made of brass with an outer diameter of 10 mm, an inner diameter of 6.2 mm and a length of 40 mm. A through hole with a diameter of 10.2 mm is drilled at the center of the back of the second fixing plate 402. The connecting sleeve 404 is inserted into the through hole, ensuring that it protrudes 2 mm from the back of the second fixing plate 402. The silver-based solder (BAg-5) is used for brazing at 350°C, and the welding time is about 30 seconds.

[0107] S56: The outer wall of the connecting rod 405 and the inner wall of the connecting sleeve 404 are movably connected and inserted.

[0108] This step ensures that the roughness Ra of the outer surface of the connecting rod 405 and the inner surface of the connecting sleeve 404 does not exceed 0.4μm. Apply a layer of molybdenum disulfide grease on the surface of the connecting rod 405 with a thickness of about 0.05mm. Carefully insert the connecting rod 405 into the connecting sleeve 404 and check whether it slides smoothly. The sliding resistance should not exceed 0.5N.

[0109] S57: Sleeve the first spring 403 onto the outer wall of the connecting sleeve 404 .

[0110] First check whether the inner diameter of the first spring 403 is slightly larger than the outer diameter of the connecting sleeve 404 (there should be a gap of 0.2-0.5mm). Place one end of the first spring 403 in the positioning groove on the second fixing plate 402, and then carefully put the spring on the outside of the connecting sleeve 404 until the other end enters the positioning groove of the first fixing plate 401. Make sure that the spring is not twisted or deformed.

[0111] Through the above detailed installation steps and process parameters, it can be ensured that the elastic connection mechanism between the pressing member 104 and the fixing block 201 is accurately and reliably installed.

A compression spring made of SUS304 stainless steel is selected, with a wire diameter of 1.2mm, an outer diameter of 10mm, a free length of 30mm, and a spring stiffness of about 1.5N / mm. An M8 threaded hole with a depth of 15mm is machined on the stop block 203. An M8×30mm adjusting bolt is used, which is passed through the compression spring and screwed into the threaded hole of the stop block 203. The position of the adjusting bolt is adjusted so that the compression spring applies a preload of about 10N to the second rack 507.

[0128] Through the above detailed processing and assembly steps, the fixed block 201, the slide plate 502, the gear rack mechanism and the extrusion mechanism can be accurately assembled. This design not only ensures the smooth movement of the slide plate 502, but also provides accurate position control through the gear rack mechanism. The setting of the extrusion mechanism effectively eliminates the gap between the gear rack and improves the accuracy and stability of the entire mechanism.

The position of the hole corresponds to the position of the limit rod 514 on the inner wall of the slot 501. The surface roughness Ra of the hole does not exceed 0.4 μm to ensure smooth sliding with the limit rod 514.

[0162] S83: Make the outer wall of the limiting rod 514 and the inner wall of the limiting hole 515 movably interpenetrate and connect.

[0163] Carefully place the slide plate 502 into the slot 501, and allow the limit rod 514 to pass through the limit hole 515. Ensure that the gap between the two is 0.1mm-0.2mm. Apply a layer of molybdenum disulfide grease with a thickness of about 0.02mm on the surface of the limit rod 514 to reduce friction.

[0164] S84: A third spring 513 is arranged on the front side of the slide plate 502 , and is sleeved on the outer wall of the limiting rod 514 .

[0171] S92 : Setting a second key contact 704 on the front side of the pressing member 104 .

[0172] The second key contact 704 is made of gold-plated copper alloy material, with a contact diameter of 3 mm and a thickness of 0.3 mm. The second key contact 704 is bonded to the center of the front of the pressing member 104 using conductive epoxy resin glue (such as MG Chemicals 8331). The curing condition is 60° C. for 2 hours.

[0173] S93: Setting a first key contact 703 on the back side of the slide plate 502 .

[0174] The first key contact 703 is made of the same material and size as the second key contact 704. It is also bonded to the back of the slide plate 502 using conductive epoxy resin glue, at a position corresponding to the second key contact 704. The curing conditions are the same.

[0175] S94: Dispose a first flexible circuit board 702 between the control board 701 and the first key contact 703 .

It is made using a flexible printed circuit (FPC) process, and the copper foil thickness is 1 oz (about 35 μm). One end of the first flexible circuit board 702 is connected to the first key contact 703 by hot pressing, and the other end is connected to the control board 701 by a zero insertion force (Zero Insertion Force, ZIF) connector.

[0177] S95: Set a second flexible circuit board 705 between the control board 701 and the periscope camera body 301.

[0178] The second flexible circuit board 705 is made of the same material as the first flexible circuit board 702, but the width is increased to 8mm to accommodate more signal lines. It is also made using the FPC process, and the copper foil thickness is 1oz. One end of the second flexible circuit board 705 is connected to the periscope camera body 301 through a board-to-board connector, and the other end is connected to the control board 701 through a ZIF connector.

[0179] Through the above detailed processing and assembly steps, the precise assembly of the limit mechanism, key contacts and control system can be achieved. This design not only provides the limit and buffer functions of the movement of the slide plate 502, but also realizes the reliable transmission of key signals and the control of the camera.

[0180] In actual production, the following tests are performed after assembly:

[0181] The slide is tested for at least 1,000 reciprocating motions to ensure that the limit rod and the third spring can work properly and that the sliding process is smooth and without sticking. This test is designed to verify the durability of the sliding assembly and the smoothness of its movement.

[0182] Use a multimeter to measure the conduction between the first key contact and the second key contact when pressed to ensure good contact. Test at least 10,000 times of pressing to verify the durability of the contacts and ensure the reliability and sensitivity of the keys in long-term use.

[0183] The first and second flexible circuit boards are subjected to at least 5,000 bending tests to ensure that signal transmission remains stable and reliable after repeated bending. This test is used to evaluate the durability and fatigue resistance of the flexible circuit board to ensure that it maintains good performance after multiple bending.

[0184] After the periscope camera is fully assembled, a comprehensive functional test is carried out, including key functions such as camera lifting, focusing, and image transmission, to ensure that all functions can work properly. This test is mainly used to verify the comprehensive performance of the whole machine and ensure its reliability in actual use.

[0185] In addition, in actual applications, the stiffness of the third spring should be fine-tuned to obtain the best operating feel and buffering effect. The entire assembly should be dustproof and waterproof, especially the flexible circuit board and connector parts, to ensure stable operation under various environmental conditions.

[0186] In actual production, the following additional tests can also be performed:

[0187] Reflectivity test, which uses an integrating sphere and a spectrophotometer to test the reflectivity of each internal surface after treatment to ensure that the reflectivity is below 0.3%. Wear resistance test, which conducts a standard wear resistance test on the surface after ultra-black treatment to ensure that there is no significant increase in reflectivity during long-term use. Thermal cycle test, which subjects the entire assembly to a temperature cycle of -40°C to 85°C to test the adhesion and stability of the ultra-black coating. Image quality comparison test, which compares the image quality of the treated periscope camera with that of the untreated control group, especially in low-light environments, to evaluate the improvement effect of ultra-black treatment on image quality.
