Detailed Implementation

[0029] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0030] Example

[0031] Please refer to Figures 1-6 This application provides a train head-up display device applied to a center console. The center console has a mounting slot 23. The display device includes: a mounting base plate 1, detachably mounted in the mounting slot 23, and a storage slot 4 on the side facing the opening of the mounting slot 23; a head-up display body 2, one end extending into the storage slot 4 and rotatably connected to it, and the other end extending out of the storage slot 4 and configured as a projection end 6; wherein the head-up display body 2 is housed and fitted into the storage slot 4; and a backup power supply 9, mounted on the mounting base plate 1; wherein the head-up display body 2 is used to connect to either the backup power supply 9 or the power system of the train.

[0032] The train head-up display device provided in this application embodiment, by opening a mounting slot 23 in the center console, detachably houses the mounting base plate 1 with a storage slot 4, allowing one end of the head-up display body 2 to be rotatably connected to the storage slot 4, so that it can be stored in the slot when not in use. This effectively solves the problem of dust accumulation caused by the device protruding from the center console in the prior art. Simultaneously, the train adopts a dual-mode power supply method consisting of the train power system and a backup power supply 9, which has many significant advantages. Under normal circumstances, the train power system supplies power to the display device; however, when the train power system fails, the backup power supply 9 quickly intervenes and seamlessly takes over the power supply. This mode greatly improves power supply reliability, avoids the display device from stopping operation due to power failure, and effectively ensures train operation and driving safety. Most importantly, it enhances emergency response capabilities. In the event of a sudden failure of the train power system, the backup power supply 9 can promptly provide power to the display device, ensuring driving safety.

[0033] Specifically, the aforementioned head-up display (HUD) 2 can exchange and share data with the STP system, projecting the acquired parameter data onto the windshield of the train driver's cab. The STP system can transmit important train operation-related signaling information, such as speed commands, signal indications, and route information, to the HUD 2 in real time. The HUD 2 then presents this information to the train driver in an intuitive manner, enabling the driver to obtain key train operation information more promptly and accurately, thereby improving driving safety and efficiency. Furthermore, the HUD 2 can also feed back the driver's operation information or other relevant data to the STP system, achieving two-way information flow. This allows the STP system to make corresponding adjustments and controls based on actual conditions, ensuring the safe and stable operation of the train. The aforementioned HUD 2 employs AR-HUD technology.

[0034] Optionally, the train's power supply system is typically 110V DC. To ensure the head-up display unit 2 can be used directly, a DC-DC converter is added to the power supply circuit to convert the 110V voltage to various voltage values ​​suitable for the head-up display unit 2. For example, a step-down DC-DC converter, such as the LM2596, can be used. It can efficiently step down the 110V to the required voltage, such as 12V, to power some circuits of the head-up display unit 2. For cases requiring voltage boosting, a step-up DC-DC converter, such as the MC34063, can be used to convert the lower voltage to a higher voltage to meet the requirements. In addition, overvoltage protection devices (such as metal oxide varistors (MOVs)), fuses, and filter circuits are added to the power supply circuit to achieve overvoltage protection, overcurrent protection, and protection against electrical interference.

[0035] In a preferred embodiment, the mounting base plate 1 is provided with a drive motor 22 for driving the head-up display body 2 to rotate.

[0036] In the above embodiments, the drive motor 22 achieves automated operation, eliminating the need for manual rotation of the head-up display 2, greatly improving ease of use. Especially during train operation, the driver can quickly adjust the display to a suitable angle and position via simple operation commands from the drive motor 22, ensuring clear visibility of information and avoiding distractions from manual operation, thus enhancing driving safety. Furthermore, the drive motor 22 can precisely control the rotation angle and speed, ensuring consistency and accuracy of each display rotation compared to manual rotation, providing the driver with a stable and standard display perspective, and preventing poor display quality due to variations in manual operation.

[0037] In a preferred embodiment, a positive socket 17 and a negative socket 18 are provided at the rotatable connection between the head-up display body 2 and the mounting groove 23. The positive socket 17 and the negative socket 18 are symmetrical about the rotation axis of the head-up display body 2. The positive socket 17 is connected to a positive plug 16, and the negative socket 18 is connected to a negative plug 19.

[0038] The mounting slot 23 is provided with a positive conductive sheet 15 and a negative conductive sheet 20, and the positive conductive sheet 15 and the negative conductive sheet 20 are respectively connected to the positive and negative terminals of the backup power supply 9. The positive terminal 16 and the positive conductive sheet 15 are slidably engaged, and the negative terminal 19 and the negative conductive sheet 20 are slidably engaged.

[0039] In the above embodiment, when the positive terminal 16 and the positive socket 17 are connected, and when the negative terminal 19 and the negative socket 18 are connected, the backup power supply 9 and the head-up display body 2 are connected, and the backup power supply 9 supplies power to the head-up display body 2. Furthermore, due to the rotation of the head-up display body 2, the positive terminal 16 can slide relative to the positive conductive plate 15, and the negative terminal 19 can slide relative to the negative conductive plate 20, to accommodate the rotation of the head-up display body 2.

[0040] Optionally, the conductive sheet is provided with a groove, and the insertion post is provided with a slider adapted to the groove to satisfy the relative sliding of the conductive sheet and the insertion post.

[0043] In the above embodiment, both the positive socket 17 and the negative socket 18 are concave, and their conductive parts are at the bottom of the slots of the positive socket 17 and the negative socket 18. The backup power supply 9 can only supply power when the positive plug 16 is fully inserted into the slot of the positive socket 17 and the negative plug 19 is fully inserted into the slot of the negative socket 18. If neither the positive plug 16 nor the negative plug 19 is fully inserted (i.e., the plugs are not against the bottom of the slots, but are still inside the slots of the positive socket 17 and the negative socket 18), the power supply circuit of the backup power supply 9 is disconnected. By adjusting the adjusting column 14, the positive plug 16 and the negative plug 19 can be either fully inserted or partially inserted, thereby enabling the backup power supply 9 to be powered on or off.

[0044] In a preferred embodiment, the adjusting column 14 and the telescopic groove 12 are connected by a spring 21, which is used to push the adjusting column 14 away from the telescopic groove 12.

[0045] The bottom of the telescopic groove 12 is provided with an electromagnet 11, and the adjusting column 14 is provided with a magnet 13 that magnetically engages with the electromagnet 11.

[0046] In the above embodiment, when the electromagnet 11 is energized, it attracts the magnet 13, and the adjusting column 14 compresses the spring 21. At this time, both the positive terminal 16 and the negative terminal 19 are in a partially inserted state, and the backup power supply 9 is de-energized. When the electromagnet 11 is de-energized, the spring 21 pushes the adjusting column 14 to move, so that the positive terminal 16 and the negative terminal 19 are fully inserted, and the backup power supply 9 provides power.

[0047] As a preferred embodiment, the head-up display body 2 is provided with a first heat dissipation hole 3.
