Description

Technical field

[0001] The present application relates to the field of recording devices and relates in particular to a recording device. State of the art

[0002] In the fast-paced work and life of modern people, there is often a need to record videos to document scenes. In certain situations, in particular, recording must be done discreetly to avoid arousing suspicion. Examples include covert investigations by journalists, undercover police evidence gathering, the recording of evidence during legal proceedings by lawyers, or the recording of evidence by ordinary citizens in criminal cases, etc. Currently, recording devices on the market generally consist of a housing and a camera. Because the camera is permanently attached to the housing, use is relatively cumbersome. Therefore, it is necessary to provide a more flexible and user-friendly recording device to meet users' needs. Content of the present application

[0003] To overcome the shortcomings of the prior art, the present application offers a recording device.

[0004] The technical solution by which the present application solves its technical problem is as follows.

[0005] The present application provides a recording device comprising a rotating roller, a camera, a flexible printed circuit board, and a housing. The rotating roller is arranged within the housing. The flexible printed circuit board is configured in an elongated shape. One end of the flexible printed circuit board is connected to the camera, and the other end is connected to the rotating roller. The flexible printed circuit board is arranged around the rotating roller, allowing the camera to be flexibly extended through the flexible printed circuit board.

[0006] The rotating roller can rotate elastically, allowing the flexible circuit board to be retracted elastically around the rotating roller.

[0007] The swivel roller comprises a central shaft, a mounting base, and an elastic element. The mounting base is fixed within the housing. The elastic element allows the central shaft to rotate elastically within the mounting base. The other end of the flexible circuit board is connected to the central shaft.

[0008] The elastic element is a coil spring. Therefore, a receiving space is defined in the center of the central shaft. The coil spring is arranged in the receiving space, with one end of the coil spring connected to a side wall of the receiving space and the other end of the coil spring connected to the mounting base.

[0009] The mounting base has an insertion rod. The insertion rod is inserted into the receiving chamber and connected to the second end of the coil spring.

[0010] The receiving device further includes a locking device. When the flexible circuit board is extended to a certain position, the locking device serves to lock the rotating roller in an elastic retraction direction. When the locking device releases the mechanism, the rotating roller drives the flexible circuit board to retract elastically.

[0011] A first mounting frame is arranged within the housing. The locking device comprises a ratchet wheel attached to the rotating roller and a pawl lever attached to the first mounting frame. When the pawl lever engages the teeth of the ratchet wheel, it locks the rotating roller in the elastic retraction direction. When the pawl lever disengages from the teeth, the rotating roller can drive the flexible circuit board to elastic retraction.

[0012] The locking device further comprises a sliding rod and a torsion spring. The sliding rod is attached to the first mounting frame and connected to the locking lever. A mounting axle section and a stand are arranged on the first mounting frame. The torsion spring is wrapped around the mounting axle section, with one end of the torsion spring connected to the sliding rod and the other end connected to the stand.

[0013] A second mounting frame is arranged within the housing. The locking device comprises a mounting plate attached to the swivel roller and a rocker arm attached to the second mounting frame. A locking guide is arranged on the mounting plate. The rocker arm has a locking block, and the locking block is arranged in the locking guide so that the locking block can lock the swivel roller in the elastic retraction direction.

[0014] The locking guide comprises an outer extension guide and an inner retraction guide. The locking block is located in the retraction guide. A connecting opening is defined between the extension guide and the retraction guide. A guide block is located at the connecting opening. The front of the guide block has a first guide section. The first guide section serves to insert the locking block from the retraction guide into the extension guide. The rear of the guide block has a locking groove. The locking groove has a second guide section and a third guide section. The second guide section serves to insert the locking block from the extension guide into the locking groove. The third guide section serves to insert the locking block from the locking groove into the retraction guide.

[0015] The second mounting frame has a limiting groove. The rocker arm is positioned in the limiting groove to limit its swing stroke. The locking block protrudes from the limiting groove.

[0016] The camera is located outside the housing. The flexible circuit board comprises an upper and a lower flexible circuit board, which are arranged overlapping. One end of the upper flexible circuit board forms a data connection. A second end of the upper flexible circuit board is connected to a second end of the lower flexible circuit board. One end of the lower flexible circuit board protrudes from the housing and is connected to the camera.

[0017] The second end of the upper flexible circuit board and the second end of the lower flexible circuit board are formed in one piece.

[0018] The rotating roller has a connecting rod. A bending point between the second end of the upper flexible circuit board and the second end of the lower flexible circuit board is formed around the connecting rod.

[0019] The housing has an opening. The first end of the lower flexible circuit board emerges from the housing through this opening.

[0020] A locking groove is defined on the outside of the housing, corresponding to the opening. The camera is locked into this locking groove.

[0021] The camera lens is either facing towards the housing or away from the housing.

[0022] A main circuit board is located inside the housing. The data connection of the upper flexible circuit board is connected to the main circuit board.

[0023] The present application further provides a recording device comprising a rotating roller, a camera, and a flexible printed circuit board. The flexible printed circuit board is configured in an elongated shape. One end of the flexible printed circuit board is connected to the camera, and a second end of the flexible printed circuit board is connected to the rotating roller. The flexible printed circuit board is arranged around the rotating roller, allowing the camera to be flexibly extended by the flexible printed circuit board.

[0024] The rotary roller is a rotating roller that can rotate elastically, allowing the flexible circuit board to be elastically retracted around the rotary roller.

[0025] The advantageous effect of the present application is as follows: Due to the structural arrangement described above, the camera or the flexible circuit board is pulled during use, causing the rotating roller to rotate in the extension direction, thus flexibly extending the camera and the flexible circuit board. During recording, the housing can be positioned as desired, allowing for more flexible and convenient use. Furthermore, the flexible extension of the camera can be suitable for a wider range of application scenarios, particularly for covert recording in special situations.For example, the housing can be placed in a backpack, and the flexible extension of the circuit board allows the camera to be extended to the backpack opening for easier shooting; or the housing can be placed in a clothing pocket, and the flexible extension of the circuit board allows the camera to be extended to the pocket opening for easier shooting. Naturally, the user can position the housing according to the desired application scenario, and not all application scenarios are listed here individually.

[0026] After use, the flexible circuit board is rewound around the rotating roller for convenient storage. The camera can still record even with the flexible circuit board wound around the roller, allowing the user to adjust its operation according to the desired application.

[0029] With reference to the Fig. A receiving device, comprising a rotating roller 1, a camera 2, a flexible circuit board 3, and a housing 4, is described in sections 1 to 5. The rotating roller 1 is arranged within the housing 4. The flexible circuit board 3 is elongated. One end of the flexible circuit board 3 is connected to the camera 2. A second end of the flexible circuit board 3 is connected to the rotating roller 1, and the flexible circuit board 3 is arranged around the rotating roller 1, allowing the camera 2 to be flexibly extended by the flexible circuit board 3.

[0030] The structural arrangement described above causes the camera or flexible circuit board to be pulled during use, which in turn causes the rotating roller to turn in the extension direction, thus extending the camera and circuit board flexibly. During recording, the housing can be positioned as desired, allowing for more flexible and convenient use. Furthermore, the flexible camera extension can be suitable for a wider range of applications, particularly for covert recording in special situations.For example, the housing can be placed in a backpack, and the flexible extension of the circuit board allows the camera to be extended to the backpack opening for easier shooting; or the housing can be placed in a clothing pocket, and the flexible extension of the circuit board allows the camera to be extended to the pocket opening for easier shooting. Naturally, the user can position the housing according to the desired application scenario, and not all application scenarios are listed here individually.

[0031] After use, the flexible circuit board is rewound around the rotating roller for convenient storage. The camera can still record even with the flexible circuit board wound around the roller, allowing the user to adjust its operation according to the desired application.

[0032] The rotating roller 1 is an elastically rotatable roller, allowing the flexible circuit board 3 to be elastically retracted around the rotating roller 1. After use, the rotating roller can elastically rotate in the retraction direction of the flexible circuit board, so that the flexible circuit board automatically wraps itself around the rotating roller for storage.

[0033] Specifically, the rotary roller 1 comprises a central shaft 11, a mounting base 12, and an elastic element 13. The mounting base 12 is fixed in the housing 4. The elastic element 13 allows the central shaft 11 to rotate elastically within the mounting base 12. The second end of the flexible circuit board 3 is connected to the central shaft 11.

[0034] Furthermore, the elastic element 13 is a coil spring. Therefore, a receiving chamber 111 is defined in the center of the central shaft 11. The coil spring is arranged in the receiving chamber 111, with one end of the coil spring connected to the side wall of the receiving chamber 111 and the other end of the coil spring connected to the mounting base 12. When the user pulls the camera or the flexible circuit board to extend the camera, the central shaft rotates in the extension direction, thereby rotating the first end of the coil spring and elastically compressing it. After use, the coil spring elastically rebounds, and the central shaft rotates elastically in the retraction direction to retract the flexible circuit board.

[0035] Furthermore, an insertion rod 121 is arranged on the mounting base 12. The insertion rod 121 is inserted into the receiving chamber 111 and connected to the second end of the coil spring. A clamping groove 122 is formed on the end section of the insertion rod, into which the second end of the coil spring is inserted to achieve the connection.

[0036] The receiving device further includes a locking device 5. When the flexible circuit board 3 is extended to the position, the locking device 5 serves to lock the rotary roller 1 in the elastic retraction direction; when the locking device 5 releases the locking mechanism, the rotary roller 1 drives the flexible circuit board 3 to elastic retraction, enabling convenient use and a well-thought-out design.

[0037] With reference to the Fig. In a first structure of the locking device, the housing 4 has a first mounting frame 41, as described in Figures 6 to 12. The locking device 5 comprises a ratchet wheel 51 attached to the rotating roller 1 and a pawl lever 52 attached to the first mounting frame 41. When the pawl lever 52 engages the ratchet teeth 53 of the ratchet wheel 51, it locks the rotating roller 1 in the elastic retraction direction. When the pawl lever 52 disengages from the ratchet teeth 53, the locking action is released, and the rotating roller 1 can drive the flexible circuit board 3 for elastic retraction. The ratchet wheel 51 can be connected to the central shaft 11 of the rotating roller 1, and the mounting base 12 of the rotating roller 1 can be attached to the first mounting frame 41.

[0038] Specifically, the locking device 5 further comprises a sliding rod 54 and a torsion spring 55. The sliding rod 54 is attached to the first mounting frame 41 and connected to the locking lever 52. A mounting shaft 42 and a stand 43 are arranged on the first mounting frame 41. The torsion spring 55 is placed around the mounting shaft 42, with one end of the torsion spring 55 connected to the sliding rod 54 and the other end of the torsion spring 55 connected to the stand 43. When the user pulls the camera 2 or the flexible circuit board 3, the presence of the locking wheel 51 does not impede the extension of the flexible circuit board 3. After the extension of the flexible circuit board 3 is completed, the locking pawl lever 52 on the slide rod 54 engages the ratchet teeth of the ratchet wheel 51 under the action of the torsion spring 55 to lock the rotating roller 1 and prevent elastic retraction of the flexible circuit board 3.If the flexible circuit board 3 is to be retracted elastically, the user can operate the slider 54 to push the locking lever 52 out of the ratchet teeth, thus releasing the locking mechanism, so that the rotary roller 1 elastically retracts the flexible circuit board 3. This is easy to operate and convenient in use.

[0039] With reference to the Fig. In a second structure of the locking device, as shown in Figures 13 to 20, the housing 4 has a second mounting frame 44. The locking device 5 comprises a mounting plate 56 attached to the swivel roller 1 and a rocker arm 57 attached to the second mounting frame 44. A locking guide 58 is arranged on the mounting plate 56. A locking block 571 is arranged on the rocker arm 57, and the locking block 571 is arranged in the locking guide 58, so that the locking block 571 can lock the swivel roller 1 in the elastic retraction direction. The mounting plate 56 can be connected to the central shaft 11 of the swivel roller 1, and the mounting base 12 of the swivel roller 1 can be attached to the second mounting frame 44.

[0040] Specifically, the locking guide 58 comprises an outer extension guide 581 and an inner retraction guide 582. The locking block 571 is arranged in the retraction guide 582. A connecting opening 583 is arranged between the extension guide 581 and the retraction guide 582. A guide block 584 is arranged at the connecting opening 583. The front of the guide block has a first guide section 585. The first guide section 585 serves to insert the locking block 571 in the retraction guide 582 into the extension guide 581. The rear of the guide block 584 has a locking groove 586. The locking groove 586 has a second guide section 587 and a third guide section 588. The second guide section 587 serves to insert the locking block 571 in the extension guide 581 into the locking groove 586.The third guide section 588 serves to introduce the locking block 571 into the locking groove 586 in the retraction guide 582.

[0041] When in use, if the user pulls the camera 2 or the flexible circuit board 3, it rotates, with reference to Fig. 16, the rotating roller 1 (mounting plate 56) in the extension direction, and the retraction guide 582 and the locking block 571 move relative to each other; and when the locking block 571 is positioned opposite the connecting opening 583, the rotation of the rotating roller 1 and the oscillation of the locking block 571 cause the locking block 571 to fall into the extension guide 581 under the action of the first guide section 585. As the flexible circuit board 3 extends, the extension guide 581 moves accordingly relative to the locking block 571. With reference to Fig. 17. When the user stops pulling, the rotary roller 1 can rotate slightly in the retraction direction due to its elastic rotatability, i.e., the flexible circuit board 3 retracts partially elastically, so that the locking block 571 is positioned opposite the connecting opening 583 in the retraction direction, and under the action of the second guide section 587, the locking block 571 is inserted into the locking groove 586 in the extension guide 581 to lock the rotary roller 1. With reference to Fig. 18. When the flexible circuit board 3 is to be retracted, the user pulls the flexible circuit board 3 slightly, i.e., the rotary roller 1 rotates slightly in the extension direction, and under the action of the third guide section 588, the locking block 571 is inserted into the locking groove 586 in the retraction guide 582, so that the locking block 571 exits the locking groove 586 and thus the locking mechanism is released. With reference to Fig. 19, with the elastic rotation of the rotary roller 1 in the retraction direction, the flexible circuit board 3 retracts further, and the retraction guide 582 moves accordingly relative to the locking block 571. With reference to Fig. 20 The locking block 571 remains within the retreat guide 582 after completion of the retreat.

[0042] Furthermore, the second mounting frame 44 has a limiting groove 45. The rocker arm 57 is arranged in the limiting groove 45 to limit its swing stroke. The locking block 571 protrudes from the limiting groove 45. The structure is simple and facilitates assembly.

[0043] In the recording device, the camera 2 is arranged outside the housing 4. The flexible circuit board 3 comprises an overlapping upper flexible circuit board 21 and a lower flexible circuit board 22. A first end of the upper flexible circuit board 21 forms a data port 23. A second end of the upper flexible circuit board 21 is connected to a second end of the lower flexible circuit board 22. A first end of the lower flexible circuit board 22 extends from the housing 4 and is connected to the camera 2. During use, the rotating roller 1 rotates in the extension direction, extending the lower flexible circuit board 22 with the camera 2 outwards, while the upper flexible circuit board 21 always remains inside the housing 4 and serves as the data port 23.As the rotating roller 1 turns in the retraction direction, the upper and lower flexible circuit boards 21, 22 retract synchronously, overlapping and wrapped around the rotating roller 1. The design is ingenious and clever.

[0044] The second end of the upper flexible circuit board 21 and the second end of the lower flexible circuit board 22 are formed in one piece.

[0045] Furthermore, the rotating roller 1 has a connecting rod 14. The bending point 24 between the second end of the upper flexible circuit board 21 and the second end of the lower flexible circuit board 22 is formed around the connecting rod 14. A through-hole may be formed at the bending point, which is placed around the connecting rod 14.

[0046] The housing 4 has an opening 43'. The first end of the lower flexible circuit board 22 emerges from the housing 4 through the opening 43'.

[0047] Furthermore, a locking groove 46 is arranged on the outside of the housing 4, corresponding to the opening 43'. The camera 2 is locked into the locking groove 46.

[0048] Furthermore, the lens of camera 2 is aligned towards the housing 4. For recording, camera 2 must be folded out of the locking slot 46. Alternatively, the lens of camera 2 can be turned away from the housing 4, allowing direct recording.

[0049] The housing 4 contains a main circuit board 6. The data connector 23 of the upper flexible circuit board 21 is connected to the main circuit board 6. The housing 4 also contains a battery 7 for power supply. The main circuit board has a charging connector 61 for charging the battery 7 and a memory card slot 62 for inserting a memory card. The housing 4 also has an operating button 8.

[0050] The foregoing description provides one or more embodiments combined with specific content and is not to be construed as limiting the concrete implementation of the present application to these explanations. All approximations or similarities to the method, structure, etc., of the present application, or any technical derivations or substitutions made under the concept of the present application, should be considered within the scope of protection of the present application.
