[0055] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0056] See Figures 2 to 7 As shown;

[0057] This embodiment provides a dining car table for a high-speed train with wireless charging function. The dining car table includes a tabletop structure 10 and a supporting frame structure 20 disposed at the lower part of the tabletop structure 10 and used to connect to the side wall of the train body.

[0058] In this embodiment, the supporting frame structure 20 includes a supporting part 1 connected to the side wall of the vehicle body and a bearing part 2 for supporting the bottom surface of the tabletop structure 10.

[0059] The support portion 1 of the support frame structure 20 is configured such that the cross-sectional dimensions gradually increase from its lower end to its upper end; the support frame structure 20 has a connecting structure on the side near the vehicle body side wall, and is assembled and fixed to the vehicle body side wall through the connecting structure;

[0060] The desktop structure integrates multiple sets of wireless charging modules 30, and the area where each set of wireless charging modules 30 is located is a wireless charging area.

[0061] Specifically, the dining car table in this embodiment consists of a bottom supporting frame structure 20 and a top tabletop structure 10. The supporting frame structure 20 serves as the supporting component for the tabletop structure 10, supporting it at the top and being fixed to the side wall of the train body on the sides, thus securing the tabletop structure 10 to the inside of the side wall. To accommodate the large-sized tabletop structure 10 and ensure its stability, the supporting frame structure 20 is divided into a supporting part 1 and a load-bearing part 2. The supporting part 1 features a triangular cross-section design that satisfies both load-bearing capacity and lightweight design requirements. Furthermore, the large load-bearing part, nearly the same size as the tabletop structure 10, supports the bottom surface of the tabletop structure 10, resulting in better tabletop stability.

[0062] Secondly, the desktop structure 10 of this embodiment integrates multiple sets of wireless charging modules 30, giving the desktop structure 10 multiple wireless charging areas, such as... Figure 4 As shown, it can meet the requirements of multiple users charging at the same time.

[0063] See Figure 2 and Figure 3 As shown, preferably, the bottom of the support part 1 in this embodiment is a bottom mounting surface 101 that is assembled and fixed to the vehicle body ground; secondly, in order to assemble with the vehicle body side wall, the support part 1 in this embodiment has a mounting beam 102 on the side near the vehicle body side wall, and the mounting beam 102 is provided with multiple mounting inner shafts 103, and the support frame structure 20 is assembled and fixed to the vehicle body side wall through the mounting inner shafts 103.

[0064] Depend on Figure 2As can be seen, multiple mounting beams 102 are installed inside the support part 1. The mounting beams 102 can further improve the structural stability of the support part. Multiple mounting inner shafts 103 are arranged on the mounting beams 102 according to the position of the side wall mounting parts. Finally, the support part 1 and the side wall structure are assembled by bolts or other mounting parts inside the mounting inner shafts 103. Since the support part 1 is basically flush with one end of the table structure 10, the table structure 10 can be kept close to the inner side of the vehicle body side wall after assembly, thus better supporting the table structure 10.

[0065] See Figure 2 As shown, preferably, in this embodiment, the side of the support part 1 closest to the vehicle body side wall is a flat surface, and the side of the support part 1 away from the vehicle body side wall is an arc-shaped surface; the upper end of the support part 1 is integrally formed with the bearing part 2.

[0066] In order to further increase the contact area with the desktop structure 10 and improve the support effect, the upper ends of the support part 1 and the bearing part 2 of the support frame structure 20 in this embodiment are both extended outward to form a support plate 3 supporting the bottom surface of the desktop structure 10; the cross-sectional dimension of the support plate 3 is greater than the sum of the cross-sectional dimensions of the support part 1 and the bearing part 2.

[0067] See Figure 5 As shown, preferably, the desktop structure 10 of this embodiment includes an aluminum frame 5 located on the outer periphery; a liner 6 disposed on the inner side of the aluminum frame 5; and a PC panel 4 fixed to the upper and lower surfaces of the liner 6; the liner 6 in this embodiment is used to integrate a wireless charging module 30.

[0068] In order to integrate the wireless charging module 30, the area of ​​the liner 6 used to integrate the wireless charging module 30 in this embodiment is configured as a groove structure 601, and the wireless charging module 30 is embedded in the groove structure 601; multiple sets of wireless charging modules 30 are arranged at intervals along the length direction of the liner 6, and the controller 31 is integrated at the end of the liner 6 near the side wall of the vehicle body.

[0069] The wireless charging module 30 involved in this embodiment is a mature existing technology. This application further defines the composition and working principle of the wireless charging module 30; see [link to relevant documentation]. Figure 6 As shown, the wireless charging module 30 in this embodiment includes a charging status display 7 and a charger;

[0070] See Figure 5 As shown, the charging status display 7 has 38 LED indicator lights 701 arranged around its circumference. The controller 31 controls the indicator light switches and color changes of the charging status display 7 to indicate the usage status of the wireless charging module 30 in that area. The charger is arranged in the hollow area in the middle of the charging status display 7.

[0071] This embodiment takes three sets of charging induction coils 8 as an example for further explanation and illustration: The charger has three sets of charging induction coils 8, and the three sets of charging induction coils 8 are arranged in a stacked manner;

[0072] See Figure 6 As shown, the stacking arrangement of the charging induction coils 8 in this embodiment is as follows: two sets of charging induction coils 8 are arranged side by side in the lower layer, and a third set of charging induction coils 8 is arranged in the upper layer, and both sets of charging induction coils 8 in the lower layer partially overlap.

[0073] First, to meet the requirements of lightweight design, the desktop structure 10 in this embodiment consists of an outer aluminum frame 5, an inner composite material liner 6, and a PC panel 4. The PC panel 4 is a light-transmitting structure, and its surface can be decorated with patterns to enhance the aesthetics of the desktop when the indicator lights shine through. Simultaneously, the wireless charging module 30 in this embodiment consists of a charging status display 7 and a charger. During integration, both are connected to the controller 31 via wiring, which is arranged along the grooves machined into the liner. The circuit board of the charging status display 7 in this embodiment is connected to and has a ring of LED indicator lights 701 arranged around it. In this embodiment, 38 indicator lights 701 are preferred. The charger is located inside the display. The charger in this embodiment has three sets of charging induction coils 8, arranged in the stacked configuration described above. Since the wireless charging function of the charging induction coils 8 is common knowledge, this application does not further limit its working principle; it only requires the integration of existing mature products into the liner 6.

[0074] Another design feature of this embodiment is the indicator light changes displayed by the charging status display 7 when the wireless charging module 30 is in use. In this embodiment, the charging status display 7 has 38 indicator lights 701 arranged circumferentially. The charging status display 7 and the charging induction coil 8 are connected via a handshake procedure. When the wireless charging module 30 enters charging mode, the charging induction coil 8 sends a notification signal to the charging status display 7 (LED circuit control board) via the handshake procedure. The charging status display 7 then displays the corresponding status based on the charging status, such as... Figure 7 The arrangement of the LED indicator 701 is as follows:

[0075] 1. Malfunction (red light);

[0076] 2. During charging, the charging status display 7 controls a set of six adjacent LED indicator lights 701 installed on it to sequentially turn off or increase the power level, thereby creating an effect of light "flowing" between the LED beads to indicate the charging status of the wireless charger.

[0077] In this embodiment, the charging status display 7 uses a color LED panel with specification model SA3H.

[0078] See Figure 4 As shown, the position of the PC panel 4 located on the upper surface of the desktop structure 10, which cooperates with the wireless charging area, forms a charging area mark 11.

[0079] In the above technical solution, the dining car table with wireless charging function provided by the present invention has the following beneficial effects:

[0080] The structure of this invention meets the requirements of lightweight design, has a large load-bearing capacity, and can meet both dining needs and the needs of multiple users for wireless charging of mobile phones.

[0081] The support part 1 of the bottom support frame structure 20 of the tabletop of the present invention provides sufficient support in a triangular structure, and the top support part 2 further supports the entire tabletop in a manner close to the size of the tabletop structure, providing stronger support stability; at the same time, by using the support part 1 to connect with the side wall of the vehicle body, the tabletop structure 10 can be more stably assembled on the inner side of the side wall, and is easy to assemble and disassemble.

[0082] The desktop structure 10 of the tabletop of the present invention integrates three sets of wireless charging modules 30, and the indicator lights are controlled by the controller 31 to indicate the usage status of the wireless charging modules 30, which is more beautiful and eye-catching.

[0083] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
