[0002] Vehicles have blind spots while driving, especially medium and large-sized construction vehicles, whose blind spots are much larger than those of smaller cars. Therefore, many medium and large-sized construction vehicles are equipped with driver assistance systems. These systems use electronic devices to help detect the surrounding environment of the vehicle. If there are vehicles or people passing by, the driver assistance system will send a warning signal to the driver, reminding them to drive cautiously, thereby improving driving safety.

[0003] Millimeter-wave radar systems are a common type of driver assistance system. They primarily consist of externally mounted millimeter-wave radar sensors and a display and control unit installed in the driver's cab. The display allows the driver to observe the operational status of the various millimeter-wave radar sensors and other relevant parameters. Currently, existing displays are typically fixed structures, secured to a specific location in the driver's cab with screws. However, once installed, their orientation and angle cannot be adjusted as needed, making it inconvenient for drivers of different sizes and resulting in a poor user experience.

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figure 1-3 As shown, a display device for a vehicle-mounted millimeter-wave radar system includes a housing 1 and a bracket 2. The housing 1 and bracket 2 are adjustablely connected. The housing 1 is a frame-shaped structure with one open end. An installation cavity is provided inside the housing 1, and a control board 3 and multiple digital tubes 4 are fixedly installed within the cavity. The control board 3 is connected to the control center of the vehicle-mounted millimeter-wave radar system. The digital tubes 4 are electrically connected to the control board 3 and are used to display various data, including but not limited to monitoring data from the radar probe, ambient temperature and humidity, etc. A transparent cover 5 is provided at the open end of the housing 1, allowing light emitted from the digital tubes 4 to pass through the transparent cover 5. During operation, the light emitted by the digital tubes 4 illuminates the transparent cover 5 and passes through it, enabling the driver to view the content displayed on the digital tubes 4, thus meeting display requirements.

[0023] One end of the housing 1 is provided with a connecting part 11, and one end of the bracket 2 is provided with two connecting ears 21. The two connecting ears 21 are respectively sleeved on both sides of the connecting part 11 and are respectively hinged to the connecting part 11. The connecting part 11 can rotate and swing along the hinge end. During installation, the vehicle-mounted millimeter-wave radar system display device can be fixedly installed in the preset installation position in the cab by the bracket 2. During use, if the user needs to adjust the viewing angle of the display device, the connecting part 11 can be rotated and swinged along the hinge end by pushing the housing 1, thereby adjusting the orientation angle of the housing 1 to achieve the purpose of adjusting the viewing angle of the display device.

[0024] The display device of this vehicle-mounted millimeter-wave radar system can be adjusted at any angle by pushing the connecting part 11 to rotate and swing along the hinge end, making it convenient for drivers of different heights to view. This makes it suitable for the needs of drivers of different heights, improving its practicality and versatility, and enhancing the user experience.

[0025] In this embodiment, the connecting part 11 is provided with a first through hole 12, the connecting ear 21 is provided with a second through hole 22, and the connecting ear 21 is provided with a fixing bolt 23, which passes through the second through hole 22 and the first through hole 12 respectively. The housing 1 and the bracket 2 are connected by the fixing bolt 23, and by installing a nut on the fixing bolt 23, the housing 1 and the bracket 2 can be fixed and limited, improving the stability of the structure. During use, if it is necessary to adjust the orientation angle, simply loosen the nut to push the housing 1 to rotate and swing along the fixing bolt 23, and then tighten the nut again after adjustment.

[0026] To improve the stability of angle adjustment, multiple positioning protrusions 13 are provided on the mating surfaces of the connecting part 11 and the connecting ear 21. Positioning grooves 24 are provided on the connecting ear 21 at corresponding positions to the positioning protrusions 13, allowing the positioning protrusions 13 to engage with the positioning grooves 24. When angle adjustment is needed, loosening the fixing bolt 23 allows the housing 1 to rotate and swing. The positioning protrusions 13 on the connecting part 11 will move between the positioning grooves 24. After adjusting to the appropriate position, the fixing bolt 23 can be tightened. The engagement of the positioning protrusions 13 with the positioning grooves 24 not only limits and fixes the housing 1 and the bracket 2, preventing unnecessary swinging of the housing 1, but also improves the feel of angle adjustment by allowing the user to judge whether the positioning protrusions 13 are properly engaged with the positioning grooves 24 through force feedback.

[0027] In this embodiment, the connecting ear 21 has 12 positioning grooves 24 evenly distributed in a circle, and the number of positioning protrusions 13 is the same as the number of positioning grooves 24, and their positions correspond one-to-one. In other embodiments, the number of positioning grooves 24 and positioning protrusions 13 can also be any other number.

[0028] To facilitate the fixed installation of the vehicle-mounted millimeter-wave radar system display device at a predetermined position, mounting holes 25 are provided on the bracket 2. By installing mounting screws into the mounting holes 25, the bracket 2 can be fixed to the predetermined position, thereby fixing the entire vehicle-mounted millimeter-wave radar system display device to the predetermined position. There are two mounting holes 25; in other embodiments, the number of mounting holes 25 can be any other number.

[0029] In the driver's cab of some vehicles, it may be inconvenient to install fixing screws. Therefore, double-sided adhesive 6 is provided on the lower end surface of bracket 2. The bracket 2 can be attached to the preset position by using double-sided adhesive 6 to meet the usage requirements.

[0030] A horn 7 is fixedly installed inside the housing 1. The horn 7 is electrically connected to the control board 3. A sound outlet 14 is provided on the rear surface of the housing 1 at a position corresponding to the horn 7. The horn 7 can be used to broadcast the data detected by the millimeter-wave radar probe and to issue a warning sound in time when an anomaly occurs to remind the driver to pay attention, thus meeting the needs of assisted driving. When in operation, the sound emitted by the horn 7 will be diffused outward through the sound outlet 14 so that the driver can hear it.

[0031] The housing 1 also contains a control button 8, which is electrically connected to the control board 3. One end of the control button 8 extends out of the housing 1. The control button 8 can be used to control the vehicle-mounted millimeter-wave radar system, as well as to adjust the volume, etc. Its specific functions can be adapted to actual needs.

[0032] The rear end face of the housing 1 is provided with a cable outlet hole 15. The control board 3 is provided with power cords and data cables. The cables inside the housing 1 can pass through the cable outlet hole 15 to exit the housing 1 and then connect to external devices.

[0033] The display device of this vehicle-mounted millimeter-wave radar system can be adjusted at any angle according to the needs of different drivers, so as to meet the usage needs of drivers of different sizes, thereby improving practicality and versatility. Moreover, during the adjustment process, the cooperation of the positioning protrusion 13 and the positioning groove 24 can ensure that the system can be stably supported after being adjusted to the appropriate position, preventing the housing 1 from swinging unnecessarily and improving the stability of the structure.

[0034] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
