[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] See also Figure 1 、 5 .

[0024] The berth indicator light of a sleeper vehicle of the present invention comprises a base plate 1, a shell 2 snap-fitted with the base plate 1, a circuit board 3 arranged on the base plate 1, and a position lighting lamp 4 and a berth digital lighting lamp 5 connected to the circuit board 3, and windows 201 are provided on the shell 2 at the positions corresponding to the position lighting lamp 4 and the berth digital lighting lamp 5, and each of the windows 201 is provided with a transparent plate 6, and also comprises two USB interfaces 7 connected to the circuit board 3, and the two USB interfaces 7 are respectively located on both sides of the position lighting lamp 4, and the shell 2 is further provided with two sockets 202 for the two USB interfaces 7 to pass through.

[0025] The utility model relates to a sleeper vehicle berth indicator light. In addition to the original indicator light, two USB ports 7 are connected to the circuit board 3, thereby increasing the mobile phone charging function without changing the vehicle layout. The USB ports 7 are located on both sides of the position lighting 4, making it easier for passengers to find the port locations.

[0026] In this embodiment, for vehicles powered by 48V DC, the USB port 7 of this application supports 1A / 5V, for a total output power of 10W. At the same time, the lighting power of each bunk indicator light is less than 3W. Considering that each carriage has 11 bunk indicators, the total power after the upgrade is 11*(10+3)=143W. Based on this data, the required supply current is 143W / 48V≈3A.

[0027] For vehicles powered by 110V DC, the requested USB port 7 supports 2A / 5V, for a total output power of 20W. Similarly, the lighting power of each berth indicator light is less than 3W. Assuming 11 berth indicators per carriage, the total power after the upgrade is 11*(20+3)=253W. Therefore, the required supply current is 253W / 110V ≈ 2.3A.

[0028] The total power and current after the upgrade are within the tolerance range of the vehicle's existing lines and air switches, thus ensuring the safety and feasibility of the upgrade process.

[0029] In this embodiment, see Figure 2 , the position of the corresponding socket 202 of the housing 2 is convex. This design further facilitates the passenger to find the position of the socket 202 and is convenient for inserting the USB interface 7.

[0030] In this embodiment, see Figure 5 , a circle of flanges 8 are provided on the bottom plate 1, and the flanges 8 are in contact with the bottom of the USB interface 7. In this design, the USB interface 7 is supported by the flanges 8 to ensure the stability of the connection between the USB interface 7 and the circuit board 3.

[0031] In this embodiment, see Figure 3 、 5 The flange 8 has slots 801 on either side thereof, and two inverted L-shaped first clamping blocks 802 are elastically slidably disposed within the slots 801. The housing 2 has second clamping blocks 203 at locations corresponding to the slots 801, and the second clamping blocks 203 can engage with the two first clamping blocks 802. This design allows the first clamping blocks 802 to engage with the second clamping blocks 203 by moving them. This engagement also facilitates the detachable and easy disassembly of the base plate 1 and the housing 2, making it easier to repair damaged components on the base plate 1. In this embodiment, the elastic sliding of the first clamping blocks 802 is achieved by a spring.

[0032] In this embodiment, see Figure 6 The flange 8 further has a groove 803 on its side corresponding to the latching slot 801, and two shifting blocks 804 are slidably disposed within the groove 803. The two shifting blocks 804 correspond one-to-one with the corresponding first latching blocks 802, and the shifting blocks 804 can drive the corresponding first latching blocks 802 to slide. This design facilitates the movement of the first latching blocks 802 from the outside of the flange 8.

[0033] In this embodiment, see Figure 7 The first clamping blocks 802 have a wedge-shaped notch 8021 on one side where they are close to each other, and the second clamping block 203 has wedge-shaped sides that match the two first clamping blocks 802. This design allows the second clamping block 203 to be directly aligned with the gap between the two first clamping blocks 802 and pressed when connecting the housing 2 to the base plate 1. This allows the two first clamping blocks 802 to move away from each other first. After the second clamping block 203 enters, the two first clamping blocks 802 are reset due to the elastic force of the spring and engage with the second clamping block 203.

[0034] In this embodiment, see Figure 3 、 5The flange 8 is also provided with a plurality of slots 805, each of which is provided with a spring. The housing 2 is also provided with a plurality of plugs 204 that can be plugged into and mate with the slots 805 in a one-to-one correspondence. This design allows the slots 805 to cooperate with the plugs 204 and the springs, so that when the housing 2 and the base plate 1 are disassembled, the housing 2 will automatically pop out due to the elastic force of the springs on the plugs 204, facilitating the disassembly operation.

[0035] In this embodiment, see Figure 3 、 4 A mounting block 9 is provided on the inside of the housing 2 at the location of the window 201 corresponding to the bunk number indicator 5. The mounting block 9 has a semi-through slot 901 formed therein, and a light-transmitting slot 902 extending vertically through the mounting block 9 and communicating with the semi-through slot 901. This design facilitates installation of the bunk number indicator on the housing 2, and the light-transmitting slot 902 allows the light from the bunk number indicator 5 to pass through, highlighting the number on the indicator.

[0036] It should be noted that if the embodiments of the present invention involve directional indications such as up, down, left, right, front, back, etc., then the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indications will also change accordingly.

[0037] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or schemes in which A and B are satisfied at the same time. In addition, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0038] It should be understood that the examples and implementation methods described herein are for illustrative purposes only and are not intended to limit the present invention. Those skilled in the art may make various modifications or changes based on them. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
