Description
TECHNICAL FIELD
[0001] The present application relates to the field of vehicle auxiliary equipment, in particular to a circuit board structure and a driving recorder. BACKGROUND
[0002] With the continuous upgrading of automobile intelligence and safety needs, the driving recorder has developed from basic video recording function to multi-module integration direction. In addition to the core video acquisition, GPS positioning, radar warning, Wi-Fi data transmission and other functions have gradually become mainstream configurations, which puts forward higher requirements on the compatibility and integration of the internal connection structure of the device. Among them, the rotating shaft, as a key component connecting the host and the lens assembly, not only needs to realize the angle adjustment function, but also needs to bear the core role of internal signal transmission, and its connection mode directly affects the overall performance and design rationality of the device. At present, the rotating shaft and the host connection part of the driving recorder in the industry generally adopt a coaxial line scheme. This scheme, with mature signal transmission stability, has been widely used in early single-function devices, mainly used to connect the GPS positioning module to realize real-time acquisition and data return of vehicle location information. The coaxial line can effectively reduce external electromagnetic interference through the structural design of the shielding layer and the core wire, ensuring the accuracy of the GPS signal during transmission, meeting the use requirements of the basic positioning function, and becoming the mainstream choice in the early industry. However, with the continuous increase of the function modules of the driving recorder, the limitations of the coaxial line connection scheme gradually become apparent. On the one hand, its functional compatibility has obvious shortcomings, only supporting a few single signal transmission such as GPS module, which cannot meet the demand of simultaneous connection of multiple modules, and is difficult to adapt to the development trend of integrated devices; on the other hand, the structure characteristics of the coaxial line itself lead to a larger occupied space, increasing the difficulty of internal structure layout.

[0022] First embodiment The circuit board structure of the present embodiment has a first end portion 11 and a second end portion 12, which are respectively used to be coupled with a first processing module and a second processing module. The first end portion 11 and the second end portion 12 are continuous and at least partially deformable, and a deformable portion 13 is arranged between the actuating mechanism and the rotating shaft 41. When the actuating mechanism rotates in a first direction, the deformable portion 13 deforms along the direction of the outer circumferential sidewall of the rotating shaft 41. When the actuating mechanism rotates in the opposite direction of the first direction, the deformable portion 13 can restore to its original state.
[0023] In this embodiment, reference is made to Figures 1 to 5 The circuit board structure 1 is used to connect the first processing module and the second processing module, and can transmit signals in the first processing module to the second processing module. For example, the first end portion 11 on the left side of the circuit board structure 1 is coupled with the first processing module, which can realize signal connection between the two. The second end portion 12 on the right side of the circuit board structure 1 is coupled with the second processing module, which can realize signal connection between the two. The processors in the first processing module and the second processing module are existing processors. The first processing module is various functional sensors, such as image collectors, temperature sensors, humidity sensors, etc. The first processing module collects information such as images, temperatures, and humidity of the external environment, and transmits the information to the second processing module through the circuit board structure 1. The second processing module is a comprehensive processor, such as an integrated circuit board 31 or a single-chip microcomputer, which can process the input information and make preset operations according to the signals.
[0024] Further, the part between the first end portion 11 and the second end portion 12 of the circuit board structure 1 is continuous, capable of realizing signal transmission, and at least partially deformable. The actuating mechanism is rotationally connected with the rotating shaft 41, and an operator can rotate the actuating mechanism relative to the rotating shaft 41 by applying a certain torque to the actuating mechanism. The deformable portion 13 is located between the actuating mechanism and the rotating shaft 41, and by rotating the actuating mechanism along a first direction (counterclockwise direction), the deformable portion 13 is deformed along the direction of the outer circumferential sidewall of the rotating shaft 41, thereby realizing a certain degree of curling of the deformable portion 13 of the circuit board, and reducing the occupied space of the circuit board structure. By rotating the actuating mechanism along a second direction (clockwise direction) in the opposite direction, the deformable portion 13 gradually stretches and can recover to the original state.
[0025] In some embodiments, the deformable portion 13 includes a first deformation portion 131, a second deformation portion 132, and a third deformation portion 133 connected in sequence. The cross section of the first deformation portion 131 and the third deformation portion 133 along the thickness direction is "C" shaped. One end of the first deformation portion 131 is further connected with the first end portion 11, and one end of the third deformation portion 133 is further connected with the second end portion 12. The first end portion 11 and the first processing module are both provided with a connecting surface 14, and the connecting surfaces 14 of the two are parallel. The second end portion 12 and the second processing module are both provided with a connecting surface 14, and the connecting surfaces 14 of the two are parallel.
[0026] In this embodiment, the deformable portion 13 includes a first deformation portion 131, a second deformation portion 132, and a third deformation portion 133 in sequence along the direction from top to bottom, and the first deformation portion 131, the second deformation portion 132, and the third deformation portion 133 are connected in sequence. The cross section of the first deformation portion 131 and the third deformation portion 133 is "C" shaped. The first end portion 11 and the second end portion 12 are connected at the first deformation portion 131 and the third deformation portion 133, which can realize the turning of the end portions, thereby enabling the first end portion 11 and the second end portion 12 to be folded to a certain degree, and reducing the overall occupied space of the circuit board structure 1. The second deformation portion 132 is opposite to the outer circumferential sidewall of the rotating shaft 41. When the actuating mechanism rotates counterclockwise relative to the rotating shaft 41, the second deformation portion 132 is deformed and curled to a certain degree. When the actuating mechanism rotates clockwise relative to the rotating shaft 41, the second deformation portion 132 is deformed and stretched to a certain degree.
[0027] Second embodiment The driving recorder according to the embodiments of the present application includes the circuit board structure 1 in the first embodiment.

[0029] In this embodiment, the first processing module further comprises a first connector 21 installed on the corresponding processor of the first processing module, and the first connector 21 can be buckled with the first end 11, that is, the connectors of the first connector 21 and the first end 11 are parallel, and the connecting surfaces 14 of the two have a large contact area after buckling, and they can be firmly connected together through welding subsequently, thereby improving the connection strength and avoiding falling off due to external vibration. Similarly, the second processing module further comprises a second connector 32 installed on the corresponding processor of the second processing module, and the second connector 32 can be buckled with the second end 12, that is, the connectors of the second connector 32 and the second end 12 are parallel, and the connecting surfaces 14 of the two have a large contact area after buckling, and they can be firmly connected together through welding subsequently, thereby improving the connection strength and avoiding falling off due to external vibration.
[0030] By rotating the actuating mechanism along the first direction (counterclockwise direction), the flip cover 5 is gradually opened at this time, and the deformable part 13 is bent and deformed along the outer peripheral side wall direction of the rotating shaft 41, thereby realizing a certain degree of curling of the deformable part 13 of the circuit board, which can reduce the occupied space of the circuit board structure. By rotating the actuating mechanism along the second direction (clockwise direction), the flip cover 5 is gradually buckled at this time, and the deformable part 13 gradually stretches and can recover to the original state.
[0031] In some embodiments, the car video recorder further comprises a rotating shaft 41 assembly, which comprises a rotating shaft 41, a fixed bracket 42 and a rotating bracket 43; the fixed bracket 42 is installed in the body structure 8 and fixedly connected with the rotating shaft 41 at the top; the rotating bracket 43 is installed in the flip cover 5 relative to the first connector 21 and rotationally connected with the rotating shaft 41, and the rotating bracket 43 is located on the side of the first connector 21 away from the flip cover 5; the first end 11 is connected with the first connector 21 after passing through the perforation 431 of the rotating bracket 43.
[0032] In this embodiment, the fixed support 42 is arranged along the vertical direction and the bottom extends into the interior of the body structure 8, the first connector 21 and the rotating support 43 are both arranged obliquely relative to the horizontal plane, the left side of the rotating support 43 is provided with a through hole 431, and after the first end portion 11 passes through the through hole 431 from bottom to top, since the cross section of the first end portion 11 is "C" shaped, the connecting surface 14 of the first end portion 11 is parallel to the connecting surface 14 of the first connector 21, so that the two connecting surfaces 14 can be buckled with a large area, thereby improving the connection strength. Similarly, after the second end portion 12 extends into the body structure 8, the cross section of the second end portion 12 is "C" shaped, the connecting surface 14 of the second end portion 12 is parallel to the connecting surface 14 of the second connector 32, so that the two connecting surfaces 14 can be buckled with a large area, thereby improving the connection strength.
[0033] In some embodiments, the driving recorder further comprises a first cover plate 6 and a second cover plate 7; the first cover plate 6 comprises a first connecting plate body 61 and a curved portion 62 connected to the first connecting plate body 61, the first connecting plate body 61 is located on the side of the rotating support 43 away from the flip cover 5, and the curved portion 62 is arranged relative to the rotating shaft 41 and curved along the outer peripheral side wall direction of the rotating shaft 41; the first end portion 11 of the circuit board structure 1 passes through the gap between the curved portion 62 and the rotating shaft 41 and the through hole 431 in sequence, and the deformable portion 13 of the circuit board structure 1 is divided into the gap between the curved portion 62 and the rotating shaft 41. When the flip cover 5 is counterclockwise rotated, the curved portion 62 can apply appropriate pressure to the deformable portion 13, thereby promoting the curved portion 62 to be curved and deformed along the outer peripheral side wall direction of the rotating shaft 41. When the flip cover 5 is clockwise rotated, since the deformable portion 13 is located in the through hole 431 of the rotating support 43, the deformable portion 13 can stretch with the rotation of the rotating support 43, thereby restoring the original state. Moreover, the bottom of the curved portion 62 is a smooth arc-shaped portion 621, so that when the bottom of the curved portion 62 contacts the deformable portion 13, the curved portion 62 avoids scratching the deformable portion 13. The second cover plate 7 is located on the side of the first cover plate 6 away from the rotating shaft 41 and buckled on the top of the body structure 8. The second cover plate 7 buckled on the top of the body structure 8 can seal the second processing module and other components in the body structure 8.
