The terms "first," "second," "third," etc., are only for the convenience of describing this technical solution and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first," "second," "third," etc., may explicitly or implicitly include one or more of that feature. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0037] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
[0038] Please refer to Figures 1-3 This application constructs an in-vehicle device 100 integrating ETC and ADAS cameras. The in-vehicle device 100 includes a housing 1, an ADAS camera assembly 2 and an ETC assembly 3 installed within the housing 1. The ADAS camera assembly 2 is used to acquire image information from outside the in-vehicle device 100. The ETC assembly 3 is used to implement the ETC function. The in-vehicle device 100 also includes a rotating assembly 4 for supporting the rotation of the ADAS camera assembly 2 along a preset rotation axis.
[0039] Among them, reference Figure 3 The vehicle-mounted device 100 also includes an adapter board 5, which is fixedly installed inside the housing 1. This adapter board 5 can be a PCBA board, serving as an intermediate bridge for communication and electrical connections. The ADAS camera assembly 2 and the ETC assembly 3 are connected to this adapter board 5 and transmit data with an external terminal through it. For example, the ADAS camera assembly 2 transmits image information to an external terminal through the adapter board 5, and the ETC assembly communicates with the external terminal via serial port through the adapter board 5. The external terminal mentioned here can be an in-vehicle central control device with a screen, or a driving recorder that at least conforms to the national standard GB / T 19056—2021 "Automotive Driving Recorder".
[0040] Understandably, this vehicle-mounted device 100 integrates the ETC component 3 and the ADAS camera component 2 into a single housing 1 via an adapter plate 5, simultaneously providing both ETC and camera functions. This solves the space occupation problem caused by the independent installation of two devices, and also reduces manufacturing costs, installation costs, and installation difficulty. Secondly, connecting the ADAS camera component 2 and the ETC component 3 via the adapter plate 5 results in a high degree of modularity, facilitating production and subsequent maintenance. Furthermore, it resolves assembly difficulties and inconvenient maintenance issues, while avoiding the structural stress caused by a direct rigid connection between the ADAS camera component 2 and the ETC component 3. Additionally, the ADAS camera component 2 of this vehicle-mounted device 100 is rotatable for adjusting the shooting angle to meet specific shooting requirements.
[0041] The following example illustrates the structure and function of this vehicle-mounted device 100.
[0042] The housing 1 is used to house and protect the structure located within it. (See reference...) Figure 4 The housing 1 defines a cavity, which may include a first chamber 111 and a second chamber 112, respectively accommodating the ADAS camera assembly 2 and the ETC assembly 3. A slot is also provided on one side of the housing 1, which communicates with the second chamber 112. The ETC card 200 can be inserted into the second chamber 112 from this slot and interact with the ETC assembly 3.
[0043] Please refer back to the reference. Figure 2 The outer side of the housing 1 has a mounting surface 12 for connecting to the inside of the windshield of a vehicle. For example, adhesive can be applied to the mounting surface 12 and then attached to the windshield.
[0044] like Figure 2As shown, the housing 1 also has an opening 13 formed through the wall surface at the mounting surface 12. A first slot 131 for accommodating a portion of the ADAS camera assembly 2 and a second slot 132 for light-absorbing purposes are formed at the opening 13. The lens of the ADAS camera assembly 2 can be located in the first slot 131 and can capture images outside the housing 1. The second slot 132 communicates with the first slot 131. A light-absorbing structure is provided in the second slot 132. For example, the slot wall opposite the camera module 21 can be designed as a continuous sawtooth, stepped, or wavy shape. When stray light shines on these uneven surfaces, diffuse reflection occurs, and the light is scattered in various directions, making it difficult to reach the lens of the camera module 21. For example, the second slot 132 can be a deep slot, and the slot wall of the second slot 132 opposite to the camera module 21 and the opening 13 are at a certain angle (not perpendicular); this structure can guide stray light to reflect to the bottom or outside of the second slot 132, rather than directly bounce to the lens direction of the camera module 21.
[0045] See below for reference Figure 3 The ETC component 3 may include an ETC motherboard 31 and a power storage unit 32. The ETC motherboard 31 integrates an ETC communication module (such as DSRC, Dedicated Short-Range Communications), a main processing chip, a Bluetooth module, and a power management unit. It should be noted that the specific structure of the ETC communication module, main processing chip, Bluetooth module, and power management unit can be found in relevant technologies and will not be elaborated here.
[0046] The ETC mainboard 31 is connected to both the adapter board 5 and the power storage unit 32. Either the adapter board 5 or the power storage unit 32 can supply power to the ETC mainboard 31. Understandably, external power is converted by the adapter board 5 to provide operating power to the ETC mainboard 31 and to charge the power storage unit 32. When the external power is disconnected, the ETC mainboard 31 can operate using power from the power storage unit 32. If the vehicle-mounted device 100 has the ETC function activated when the external power is disconnected, the power storage unit 32 ensures that the ETC mainboard 31 continues to operate for a preset time, after which the ETC function is automatically deactivated. If the vehicle-mounted device 100 has not activated the ETC function when the external power is disconnected, the ETC function remains deactivated.
[0047] In addition, such as Figure 3 As shown, the ETC motherboard 31 also has an antenna board 33. This antenna board 33 gathers scattered signals through signal focusing function and simultaneously enhances the directional accuracy of the antenna. It can achieve signal orientation optimization without complicated debugging, helping the device maintain excellent directional communication performance in complex electromagnetic environments, and improving antenna directional performance with a lightweight design.
[0048] Continue to refer to Figure 3 The adapter board 5 can be a PCBA board, and the ADAS camera component 2 and ETC component 3 are respectively connected to the adapter board 5. The adapter board 5 adopts a modular design, integrating a power management module and a serial communication module to ensure stable and reliable data and power transmission between the ETC component 3 and the ADAS camera component 2. The adapter board 5 also has a voice broadcast module to support the broadcasting of ETC transaction information, event information, status information, etc. Correspondingly, a speaker 8 electrically connected to the voice broadcast module can also be provided inside the housing 1 to broadcast information through the speaker 8. It should be noted that the specific structure of the power management module, serial communication module, and voice broadcast function module can be found in relevant technologies and will not be elaborated here.
[0049] A wire harness 6 is also connected to the outside of the housing 1. One end of the wire harness 6 extends into the housing 1 for connection with the adapter plate 5. Figure 3 (Connection details omitted). The other end of the wiring harness 6 is located outside the housing 1 and is used to connect to an external terminal. The external terminal can provide external power to the vehicle-mounted device 100. This external power is converted into operating power after passing through the adapter board 5, supporting the operation of the ETC component 3 and the ADAS camera component 2. The external terminal can also transmit data with the ADAS camera component 2 and the ETC component 3 through the adapter board 5.
[0050] Understandably, since the wiring harness 6 only needs to be connected to the adapter board 5, the entire vehicle-mounted device 100 can obtain power and communicate with the external terminal through a single wiring harness 6, avoiding the problems of multiple wiring harnesses 6, complex connections, and messy wiring caused by the independent installation of two devices.
[0051] See again Figure 4 The ADAS camera assembly 2 may include a camera module 21 and a camera housing 22. The camera module 21 is an ADAS camera module used to acquire and process image information from in front of the vehicle. The camera module 21 includes an image sensor (such as a CMOS chip), an optical lens, an image processing chip, etc. It should be noted that the specific construction of the image sensor, optical lens, and image processing chip can be found in relevant technologies and will not be elaborated here. The camera housing 22 is used to protect the camera module 21. The camera housing 22 defines a protective cavity in which the camera module 21 is installed.
[0052] Continue to refer to Figure 4The rotating assembly 4 may include two rotating shafts 41 respectively disposed on opposite sides of the ADAS camera assembly 2, and two mounting positions 421 formed inside the housing 1 and arranged at intervals. The ADAS camera assembly 2 is disposed between the two mounting positions 421, with each rotating shaft 41 correspondingly mounted in a single mounting position 421 and configured to rotate within the mounting position 421 to allow the ADAS camera assembly 2 to rotate in the pitch direction. Furthermore, the rotating assembly 4 also includes a transmission member 43, one end of which extends outside the housing 1, and the other end of which is connected to one of its rotating shafts 41 to drive the ADAS camera assembly 2 to rotate, thereby adjusting the pitch angle of the lens of the ADAS camera assembly 2.
[0053] Understandably, the user or installer can adjust the pitch angle of the ADAS camera assembly 2's lens by manipulating the transmission component 43. It should be noted that in the illustrated embodiment, the vehicle-mounted device 100 is designed to be vertically installed in the vehicle. The pitch angle refers to the installation direction of the vehicle-mounted device 100 in this illustrated embodiment. When the vehicle-mounted device 100 is installed horizontally, the lens angle of the ADAS camera assembly 2 changes from being pitch-adjustable to being horizontally adjustable. Therefore, adjusting the horizontal angle of the ADAS camera assembly 2's lens by manipulating the transmission component 43 should also be included within the scope of protection of this application.
[0054] The two pivots 41 can be respectively attached to opposite sides of the camera housing 22. The mounting position 421 can be directly formed on the cavity wall of the first chamber 111, or two brackets 42 can be set in the first chamber 111, with a mounting position 421 formed on each bracket 42.
[0055] The transmission component 43 may include a turntable 431 and an extension arm 432. The turntable 431 is mounted on the outside of the housing 1. Correspondingly, a mounting slot 14 may also be provided on the outside of the housing 1, in which the turntable 431 can be mounted. The turntable 431 protrudes at least partially from the outer surface of the housing 1 to facilitate rotation of the transmission component 43 by the user. The extension arm 432 is inserted into the housing 1, wherein one end of the extension arm 432 is connected to the turntable 431, and the other end of the extension arm 432 extends into the first chamber 111 of the housing 1 and is connected to the adjacent rotating shaft 41.
[0056] Continue to refer to Figure 5A connecting structure is formed between the extension arm 432 and the rotating shaft 41 to achieve a relatively fixed connection between the extension arm 432 and the rotating shaft 41. For example, both the rotating shaft 41 and the extension arm 432 are cylindrical; the connecting structure may include a retaining arm 412 provided on one of the structures of the extension arm 432 and the rotating shaft 41, and a retaining groove 4321 provided on the other structure of the extension arm 432 and the rotating shaft 41; the retaining arm 412 and the retaining groove 4321 are respectively located at non-axial positions of the rotating shaft 41 and the extension arm 432, and the retaining arm 412 can be embedded in the retaining groove 4321, achieving relative fixation through the fit of the mechanical structure. As another example, the connecting structure may include a pin provided on one of the structures of the extension arm 432 and the rotating shaft 41, and a socket provided on the other structure of the extension arm 432 and the rotating shaft 41; relative fixation is achieved through the interference fit between the pin and the socket.
[0057] Secondly, please refer back to the reference. Figure 4 The vehicle-mounted device 100 also includes a fastener 7 for securing the ADAS camera assembly 2 in the first chamber 111. The fastener 7 is an elongated structure that can pass through the transmission member 43 and, after being inserted into the first chamber 111, is locked in the rotating shaft 41 to secure the transmission member 43 and the ADAS camera assembly 2 to the housing 1. After the ADAS camera assembly 2 is secured, the pitch angle of its lens remains unchanged. For example, the transmission member 43 has a hollow channel 433 for inserting the fastener 7, and the surface of the rotating shaft 41 opposite to the turntable 431 has a mounting hole 411. One end of the fastener 7 is connected to the transmission member 43, and the other end of the fastener 7 is locked in the mounting hole 411 by snap-fit or screw-fit.
[0058] Since the fastener 7 passes through the transmission component 43 and extends into the housing 1, the fastener 7 will tightly connect the turntable 431 and the groove wall of the mounting slot 14. Considering that vehicle vibration can easily cause the fastener 7 to loosen, resulting in a change in the pitch angle of the ADAS camera assembly 2 lens, a resistance structure can be designed between the turntable 431 and the groove wall of the mounting slot 14 to prevent the transmission component 43 from rotating due to vehicle vibration, thereby ensuring that the lens angle of the ADAS camera assembly 2 remains unchanged.
[0059] For example, such as Figure 4As shown, the resistance structure may include a first locking tooth 4311 disposed on the turntable 431 and a second locking tooth 141 disposed at the bottom of the mounting slot 14. The first locking tooth 4311 and the second locking tooth 141 can mesh with each other during the fastener 7 locking. At this time, under the restraining effect of the locking tooth structure, the transmission member 43 is difficult to rotate. Multiple first locking teeth 4311 and second locking teeth 141 can be provided, respectively arranged at intervals around the axial direction of the fastener 7. Optionally, the locking teeth can be arranged at intervals around the axial direction of the fastener 7 in a circular ring, arc shape, etc. For example, the resistance structure can also be a rubber sheet, which is disposed between the turntable 431 and the groove wall of the mounting slot 14. When the fastener 7 tightly connects the turntable 431 and the groove wall of the mounting slot 14, the turntable 431 will be partially embedded in the rubber sheet, thereby preventing the transmission member 43 from rotating.
[0060] It should be further noted that the mounting slot 14 is not a necessary feature of this vehicle-mounted device 100. In other embodiments without a mounting slot 14, the turntable 431 can be directly mounted on the outer surface of the housing 1, in which case the turntable 431 protrudes completely from the outer surface of the housing 1. For the resistance structure, it can be formed between the turntable 431 and the housing 1.
[0061] For reference Figure 6 The rotating assembly 4 also includes a damping element 44. One end of the damping element 44 is connected to the ADAS camera assembly 2, and the other end is connected to an internal structure of the housing located outside the ADAS camera assembly 2, so as to impede the rotation of the ADAS camera assembly 2 through contact. It is understood that the purpose of the damping element 44 is to prevent the ADAS camera assembly 2 from rotating easily, rather than to completely restrict the ADAS camera assembly 2 from rotating. The aforementioned internal structure of the housing can be the inner wall of the housing 1 or the bracket 42.
[0062] For example, the damping element 44 can be a spring arm 441. (See reference...) Figure 6 The spring arm 441 is disposed between the internal structure of the housing and the ADAS camera assembly 2. The spring arm 441 has a fixed end and a free end. The fixed end is fixedly connected to one of the internal structure of the housing and the ADAS camera assembly 2, while the free end abuts against the other structure of the internal structure of the housing and the ADAS camera assembly 2. Because the spring arm 441 has elastic deformation capability, it deforms when its free end abuts against the other structure of the internal structure of the housing and the ADAS camera assembly 2, generating an elastic force that resists the rotation of the ADAS camera assembly 2. Alternatively, the resistance structure could be a rubber sheet, which deforms when the turntable 431 rotates, generating a damping force to prevent the transmission component 43 from rotating. Alternatively, the damping component 44 could be an adhesive material disposed between the ADAS camera assembly 2 and the internal structure of the housing, resisting the rotation of the ADAS camera assembly 2 through adhesive force.
[0063] The following description will continue to illustrate the structure of the rotating component 4 using the illustrated embodiment as an example.
[0064] In the illustrated embodiment, see Figure 4 Two brackets 42 are provided in the first chamber 111, and the two brackets 42 are arranged at intervals in the width direction of the housing 1. Each bracket 42 has a through hole for use as a mounting position 421. The ADAS camera assembly 2 is disposed between the two brackets 42, and two rotating shafts 41 disposed on opposite sides of the ADAS camera assembly 2 are respectively inserted into the through holes of the two brackets 42.
[0065] Each bracket 42 is a longitudinally elongated structure, with its length direction parallel to the thickness direction of the shell 1. The first end of the bracket 42 is fixed to the cavity wall of the first chamber 111, while the second end of the bracket 42 is suspended in the first chamber 111.
[0066] For ease of explanation, the rotating shaft 41 connected to the transmission component 43 will be defined as the first rotating shaft 41a, and the other rotating shaft 41 will be defined as the second rotating shaft 41b. Figure 6 As shown, the first rotating shaft 41a is connected to the side of the ADAS camera assembly 2 opposite to the transmission member 43. The first rotating shaft 41a may be cylindrical, with an outer diameter less than or equal to the diameter of the through hole, and its axial direction parallel to the width direction of the housing 1. A screw hole (i.e., mounting hole 411) is also provided at the center of the first rotating shaft 41a for screwing with the fastener 7. The second rotating shaft 41b is connected to the side of the ADAS camera assembly 2 facing away from the transmission member 43. The structure of the second rotating shaft 41b is similar to that of the first rotating shaft 41a, and will not be described in detail here.
[0067] See below Figure 5 The first rotating shaft 41a has two retaining arms 412 extending towards the extension arm 432 on its side facing the extension arm 432. These two retaining arms 412 are symmetrically arranged along the axial direction of the first rotating shaft 41a. Correspondingly, the extension arm 432 has two retaining slots 4321 on its side facing the first rotating shaft 41a. The positions of these two slots 4321 correspond to the positions of the two retaining arms 412. When the transmission component 43 is inserted into the first chamber 111, the retaining slots 4321 are correspondingly engaged, thereby achieving relative fixation between the first rotating shaft 41a and the extension arm 432.
[0068] like Figure 5 As shown, the outward-facing port of the hollow channel 433 of the transmission component 43 is hexagonal, allowing the transmission component 43 to be rotated using a hexagonal wrench; of course, this port can also be other shapes, such as square. The turntable 431 is disc-shaped. The extension arm 432 is cylindrical and coaxially coupled to the turntable 431.
[0069] See also Figure 6The fastener 7 is a screw, which is inserted into the transmission member 43 along the axial direction of the first rotating shaft 41a. In summary, the first rotating shaft 41a, the turntable 431, the extension arm 432, and the fastener 7 are coaxially arranged, and their axes coincide with the rotation axis of the ADAS camera assembly 2. The tail of the fastener 7 extends into the first chamber 111 and is screwed onto the first rotating shaft 41a. The head of the fastener 7 is fixed in the hollow channel 433 of the transmission member 43. Understandably, the head of the fastener 7 is concealed within the transmission member 43, which effectively prevents foreign objects from contacting the fastener 7 and prevents the fastener 7 from being accidentally loosened.
[0070] like Figure 6 As shown, the spring arm 441 is connected to the side of the ADAS camera assembly 2 opposite to the transmission component 43. The fixed end of the spring arm 441 is fixed to the side of the first rotating shaft 41a away from the opening 13 of the housing 1, and the free end of the spring arm 441 extends away from the opening 13 of the housing 1. This free end is configured to abut against the structural portion between the first end of the bracket 42 and the through hole. The spring arm 441 and the bracket 42 cooperate to provide clamping force during the assembly stroke, providing damping force during rotation. Understandably, the bracket 42, which abuts against the spring arm 441, has a certain width to support the adjustment of the lens of the ADAS camera assembly 2 within a preset angle range.
[0071] The free end of the spring arm 441 is provided with a protrusion 4411 on the side facing the bracket 42, which is used to ensure the contact between the spring arm 441 and the bracket 42, and to increase the force of the spring arm 441 on the bracket 42, thereby ensuring that the ADAS camera assembly 2 will not rotate arbitrarily.
[0072] When adjusting the lens angle of the ADAS camera assembly 2 of the vehicle-mounted device 100, firstly, loosen the fastener 7. At this time, the transmission component 43 is not tightly connected to the bottom of the mounting slot 14. Then, use the tool to drive the transmission component 43 to rotate the ADAS camera assembly 2. At this time, under the rebound force of the spring arm 441, the ADAS camera assembly 2 can remain relatively stationary no matter what angle it is rotated to. At the same time, since the transmission component 43 is not tightly connected to the bottom of the mounting slot 14, the first locking tooth 4311 and the second locking tooth 141 will not mesh with each other during rotation. Finally, after adjusting to the desired angle, tighten the fastener 7 so that the transmission component 43 is tightly connected to the bottom of the mounting slot 14, and the first locking tooth 4311 and the second locking tooth 141 mesh with each other to ensure the fixation of the ADAS camera assembly 2.
[0073] In summary, this vehicle-mounted device 100 adopts a highly integrated design, integrating the ADAS camera component 2 and the ETC component 3 into the same housing 1. This not only significantly reduces the space occupied inside the vehicle but also effectively expands the driver's field of vision, making the installation of the device simpler and more aesthetically pleasing. In the installation process, the device further simplifies the procedure: the entire unit only needs to be pasted and fixed to a suitable location on the vehicle, and only one wiring harness 6 is required for the entire connection, greatly reducing wiring complexity and saving time and effort. Thanks to the shared housing 1 and some circuitry between the ADAS camera component 2 and the ETC component 3, the overall manufacturing cost of the device is significantly reduced. At the same time, the ingenious design of the adapter board 5 makes the ADAS camera component 2 and the ETC component 3 relatively independent modules. If either module is damaged, it can be disassembled and replaced individually without requiring overall repair, greatly reducing the difficulty and cost of later maintenance. In terms of functional adaptability, the device is equipped with a unique swivel-type rotating component, allowing users or installers to flexibly adjust the lens tilt angle of the ADAS camera component 2 according to the actual posture of the vehicle and the driver's sitting posture, easily obtaining the best shooting angle; the damping structure can firmly lock the adjusted angle, effectively preventing the lens from shifting due to vibration during vehicle movement, ensuring the stability of image acquisition.
[0074] Furthermore, the vehicle-mounted device 100 connects to an external terminal via wiring harness 6, enabling it to output video signals and interact with the external terminal. For example, according to the communication protocol, the vehicle-mounted device 100 can be bound one-to-one with an external terminal. Successful binding activates the ETC function, while failed binding or unbinding disables the ETC function. The vehicle-mounted device 100 can also interact with a software platform connected to the external terminal, reporting event information and responding to query and control commands from the software platform. This vehicle-mounted device 100 also features a voice broadcast function, capable of broadcasting ETC transaction information, event information, and status information.
