[0020] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. It should be clear that the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0021] As Figures 1-7 shown, in some illustrative embodiments, a truck panoramic surround view device is provided, including: a panoramic surround view controller 1, a camera group 2, and a display screen 3.

[0022] The camera group 2 sends the collected video images to the panoramic surround view controller 1. After the panoramic surround view controller 1 performs image processing and stitching, the stitched image is sent to the display screen 3, and finally presented to the driver by the display screen 3.

[0023] The panoramic surround view controller 1 includes: a housing 101, a heat sink 102, a plug-in 103, a Fakra plug group 4, a TF card mounting port 104, a support crossbar 105, a mounting plate member 106, a main chip 107, a CAN transceiver 108, an auxiliary chip 109, a deserialiser 110, and a power supply board 111.

[0024] The housing 101 is the housing part of the panoramic surround view controller. It provides protection for the internal electronic components, preventing dust, moisture, and other external factors from damaging the inside of the controller. It is usually made of durable materials such as aluminum alloy or engineering plastics. The heat sink 102 is disposed on the top of the housing 101, and its function is to effectively dissipate the heat generated by the internal electronic components of the controller during operation. The heat sink 102 is usually designed with a large surface area to enhance the heat dissipation effect.

[0025] The plug-in 103 and the Fakra plug set 4 are arranged side by side on the rear side of the housing 101. The plug-in 103 is an interface for connecting the internal circuit of the controller to external devices. Specifically, in this embodiment, it is used for power supply and CAN signal communication. The Fakra plug set 4 is used to connect the camera signal line to ensure the stable transmission of video signals. The TF card installation port 104 is arranged on the side of the housing 101 and is used to insert a TF memory card for storing video data or system update files.

[0026] The TF card installation port 104 is located on the side, which is convenient for users to insert and remove the TF card at any time for data storage and reading. At the same time, it also facilitates system upgrade and maintenance. The plug-in 103 and the Fakra plug set 4 are arranged side by side on the rear side of the housing 101. Such a layout makes the wiring harness routing clearer, facilitating installation and future maintenance. At the same time, this design helps to reduce the crossing and winding of cables and reduce electromagnetic interference. By reasonably arranging components with different functions at different positions of the housing, the panoramic surround view controller 1 maximizes the use of space while maintaining its complete functions, making the controller smaller and more suitable for installation inside a vehicle with limited space. Due to the reasonable layout of the heat sink 102, the plug-in 103, the Fakra plug set 4, and the TF card installation port 104, the panoramic surround view controller 1 can be more easily compatible with other vehicle systems and also leaves room for future function upgrades.

[0027] Grooves 1011 are opened on both sides of the bottom of the housing 101. The support crossbar 105 is arranged in the grooves 1011 and one end of the support crossbar 105 is hinged to the housing 101. Therefore, the support crossbar 105 can swing and rotate on the housing 101, thereby allowing the angle of the housing 101 to be adjusted. The mounting plate 106 is arranged on the outer side of the support crossbar 105, and through holes 1012 are opened on the mounting plate 106. The function of the mounting plate 106 is to provide a stable plane for fixing the panoramic surround view controller 1 at a specified position on the vehicle.

[0028] Installation process: During installation, first adjust the angle of the housing 101 to adapt to different installation position points. After the angle adjustment is completed, use fasteners (such as bolts and nuts) to pass through the through holes 1012 on the mounting plate 106 and tighten the fasteners to fix the panoramic surround view controller 1. Since the support crossbar 105 can swing and rotate, the angle of the housing 101 can be adjusted according to the actual installation requirements. This design enables the panoramic surround view controller 1 to adapt to different vehicle structures and installation positions, improving the versatility of the device. The design of the support crossbar 105 and the mounting plate 106 simplifies the installation process. The user only needs to adjust the angle and fix the fasteners to complete the installation without complex operation steps. Moreover, the structural design of this application provides a stable support structure to ensure that the panoramic surround view controller 1 will not shift or loosen during vehicle operation, thus ensuring the reliability and safety of the device.

[0029] The camera group 2 is connected to the panoramic surround view controller 1 through an LVDS transmission line, and the panoramic surround view controller 1 is connected to the display screen 3 through an LVDS transmission line. The video signals captured by the camera group 2 are converted into LVDS signals and then sent to the panoramic surround view controller 1 through the LVDS transmission line. The panoramic surround view controller 1 processes these signals, such as image stitching, correction, and enhancement, to generate a panoramic surround view image. The processed LVDS signals are sent to the display screen 3 through another group of LVDS transmission lines. The display screen 3 receives the LVDS signals and converts them into visible images for display to the driver. LVDS technology supports high data transmission rates, can transmit high-definition video signals, ensures that the panoramic surround view stitching image is clear and delicate, and has good anti-electromagnetic interference ability, and can maintain signal quality even in a complex vehicle electronic environment.

[0030] Each camera in the camera group 2 is a low-light camera. A low-light camera is a surveillance camera that can work in an environment with very low light conditions. It can capture clear images in a dim or nearly dark environment.

[0031] The camera group 2 includes: a front camera 201, a left front camera 202, a left rear camera 203, a right front camera 204, a right rear camera 205, and a rear camera 206. As Figures 4-7 shown, the front camera 201 is set on the front flip cover of the vehicle to collect the picture in front of the vehicle; the left front camera 202 and the left rear camera 203 are set under the left rearview mirror to collect the pictures of the left front and left rear of the vehicle respectively; the right front camera 204 and the right rear camera 205 are set under the right rearview mirror to collect the pictures of the right front and right rear of the vehicle respectively; the rear camera 206 is set at the rear end of the vehicle to collect the picture behind the vehicle. According to the actual situation of the vehicle, it can be installed at an appropriate position.

[0032] The Fakra plug set 4 includes: a front Fakra plug 401, a left front Fakra plug 402, a left rear Fakra plug 403, a right front Fakra plug 404, a right rear Fakra plug 405, and a rear Fakra plug 406 for connecting the camera set 2, and a screen Fakra plug 407 for connecting the display screen 3. The Fakra plugs are convenient and reliable to connect, not easily affected by the wiring harness process, and the imaging is stable.

[0033] The front Fakra plug 401, the left front Fakra plug 402, the left rear Fakra plug 403, the right front Fakra plug 404, the right rear Fakra plug 405, and the rear Fakra plug 406 are respectively connected to the front camera 201, the left front camera 202, the left rear camera 203, the right front camera 204, the right rear camera 205, and the rear camera 206 through LVDS transmission lines.

[0034] The screen Fakra plug 407 is connected to the display screen 3 through an LVDS transmission line.

[0035] The main chip 107 is the core processing unit of the panoramic surround view controller. It is responsible for processing the received video signals, including image correction, enhancement, stitching, etc., to generate a panoramic view of the vehicle's surrounding environment. The auxiliary chip 109 is connected to the main chip 107. Its main function is to process the communication with the vehicle's CAN network. Specifically, it receives information from the vehicle's CAN network through the CAN transceiver 108 and sends the necessary information inside the controller to the vehicle's CAN network through the CAN transceiver 108.

[0036] The CAN transceiver 108 is the interface between the auxiliary chip 109 and the vehicle's CAN network. It is responsible for converting the signals of the auxiliary chip 109 into CAN bus signals for communication with the vehicle's CAN network. The deserialiser 110 is connected to the main chip 107 and is used to convert the serial digital video signals transmitted by the camera set 2 through the LVDS transmission line into parallel signals so that the main chip 107 can more easily process these video data. The power supply board 111 is connected to the main chip 107 to provide a stable power supply for the entire panoramic surround view controller to ensure that the main chip and other components can work properly.

[0037] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered by the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
