The track socket 10 is arranged on one end of the vehicle frame away from the wheel, and the track socket 10 is horizontally arranged between two columns of the vehicle frame. The track socket 10 and the crossbeam 214 of the vehicle frame are on the same horizontal plane. Therefore, the track socket 10 can be used as one of the crossbeams 214 of the vehicle frame and can also be used as a socket, so that the structure of the vehicle body 211 is simple, which facilitates the insertion of the plug 20 on the functional module 212 into the track socket 10. During installation, the functional module 212 is snapped onto the vehicle body 211 and the plug 20 is inserted into the track socket 10 at the same time, so that the functional module 212 and the vehicle body 211 are installed and connected to electricity at the same time, simplifying the installation process, so that the user does not need to squat down and pull the power cord 204 of the plug 20 for power connection after installation.

The plug 20 is inserted into the track slot 101 through the socket and is electrically connected to the track socket 10, so that during the insertion process, the plug 20 only needs to be aligned in the front and rear directions (Z-axis direction), and then it can be inserted at any position within the range of the track slot 101, and there is no need to align the left and right directions. Therefore, not only does it make the operation of inserting the plug 20 into the track socket 10 more convenient and efficient, but it also allows the plug 20 to slide left and right along the direction of the track slot 101 after being inserted into the track slot 101. Therefore, when the left and right position of the functional module 212 needs to be adjusted, there is no need to lift the functional module 212 for adjustment, and the installation is convenient.

[0035] Further, such as Figure 2 and Figure 3 As shown, the track socket 10 is provided with a limiting groove 102 along the length direction of the track socket 10, the limiting groove 102 is located on the side of the vehicle frame facing the outside, the track socket 10 is located on the inner side of the vehicle frame, the notch of the limiting groove 102 is arranged toward the side of the functional module 212, the limiting groove 102 is a rectangular strip, and a buckle 216 is arranged at a position corresponding to the limiting groove 102 on the functional module 212. The buckle 216 can be a rectangular protrusion, a wedge-shaped protrusion, a dovetail protrusion or a strip-shaped protrusion, etc. Since the plug 20 on the functional module 212 is arranged at a position corresponding to the track slot 101, when installing, the buckle 216 is inserted into the limiting groove 102, and the functional module is pressed downward. Block 212 can make the plug 20 be inserted into the track slot 101 to achieve electrical connection, so that the installation and power connection of the car body 211 and the functional module 212 can be completed at the same time. Since the limit slot 102 and the track slot 101 are strip-shaped designs, the user does not need to visually align the plug 20 with the track slot 101 during installation to complete the installation and power connection. It is only necessary to align the position of the buckle 216 and the limit slot 101, and press the functional module 212 downward to complete the installation and power connection. The installation and power connection do not need to be performed separately, which improves work efficiency and avoids the user squatting down to pull the power cord 204 of the plug 20, and then visually aligning the socket with the socket to insert the plug 20 into the socket.

[0036] In order to further limit the function module 212 and improve the efficiency of installing the function module 212, another limiting groove 102 can be correspondingly set on the crossbeam 214 of the vehicle frame arranged opposite to the track socket 10, and another buckle 216 is provided at the other end of the function module 212. Therefore, during installation, the buckle 216 on the function module 212 and the other buckle 216 are directly aligned with the limiting groove 102 and the other limiting groove 102 respectively, and then the function module 212 is pressed downward to insert the plug 20 into the track socket 10.

[0037] In one embodiment, if Figure 4 and Figure 5 As shown, the plug 20 includes an insulator 201, multiple power cords 204 and multiple elastic conductive sheets 205. One ends of the multiple power cords 204 are all arranged in the functional module 212, and the other ends of the multiple power cords 204 pass through the functional module 212 and are arranged in the insulator 201. The insulator 201 is fitted on a side surface of the functional module 212 facing the track slot 101, and the position of the insulator 201 corresponds to the position of the track slot 101, so that the plug 20 is convenient to insert into the track slot 101, and the elastic conductive sheet 205 is arranged outside the insulator 201. A threading hole is provided in the insulator 201 corresponding to the power cord 204, and each power cord 204 passes through each threading hole and is electrically connected to each elastic conductive sheet 205. The structure of the plug 20 is compact and simple.

[0038] The material of the insulator 201 can be plastics such as PPS (polyphenylene sulfide), PBT (polybutylene terephthalate fiber), PET (polyterephthalate plastic), etc., which have good insulation properties, prevent users from electric shock, and improve safety in use.

[0039] Furthermore, the insulator 201 includes a first insulating plate 202 and a second insulating plate 203, one end of the first insulating plate 202 is connected to the power line 204, and the first insulating plate 202 is fitted on the functional module 212, and the other end of the first insulating plate 202 is vertically arranged on the second insulating plate 203. The vertical arrangement of the first insulating plate 202 and the second insulating plate 203 makes the insulator 201 have an L-shaped structure. In this embodiment, the first insulating plate 202 and the second insulating plate 203 are an integral structure, which is integrally formed during processing, so that the structure of the plug 20 is simple and the processing cost of the plug 20 is low.

[0040] For example, Figure 6 and Figure 7As shown, three elastic conductive sheets 205 are provided, specifically a live wire conductive sheet, a neutral wire conductive sheet and a ground wire conductive sheet, and three power lines 204 are provided correspondingly, and the power lines 204 are specifically a live wire, a neutral wire and a ground wire; the live wire is electrically connected to the live wire conductive sheet, the neutral wire is electrically connected to the neutral wire conductive sheet, and the ground wire is electrically connected to the ground wire conductive sheet. The live wire conductive sheet and the neutral wire conductive sheet are provided on one side wall of the second insulating plate 203, and the ground wire conductive sheet is provided on the other side wall of the second insulating plate 203. One side wall and the other side wall are two side walls arranged oppositely, and the track slot 101 is provided with a plurality of conductive sheets corresponding to the elastic conductive sheet 205. The conductive strip 103 is a long strip structure, and its length matches the length of the track socket 10 and the track slot 101, so that the track socket 10 can be energized with the elastic conductive sheet 205 of the plug 20 in the length direction. When the functional module 212 is adjusted, the plug 20 can be energized with the track socket 10 when it moves in the left and right directions, thereby making installation and power connection more convenient. Specifically, the live wire conductive strip 103, the neutral wire conductive strip 103 and the ground wire conductive strip 103. When the plug 20 is inserted into the track slot 101, the elastic conductive sheet 205 has The elastic conductive sheet 205 can be compressed toward the second insulator 201 to facilitate the insertion of the plug 20. When the plug 20 is fully inserted into the track slot 101, the live conductive sheet contacts the live conductive strip 103 to achieve electrical connection, the neutral conductive sheet contacts the neutral conductive strip 103 to achieve electrical connection, and the ground conductive sheet contacts the ground conductive strip 103 to achieve electrical connection. The elastic conductive sheet 205 is elastic and pressed against the conductive strip 103. The elasticity of the elastic conductive sheet 205 not only facilitates the insertion of the plug 20, but also keeps the functional module 212 and the vehicle body 211 electrically connected. Avoid power outages caused by poor contact; or the elastic conductive sheet 205 is set to two, specifically a live wire conductive sheet and a neutral wire conductive sheet, and the power lines 204 are correspondingly set to two, and the power lines 204 are specifically a live wire and a neutral wire; the live wire is electrically connected to the live wire conductive sheet, and the neutral wire is electrically connected to the neutral wire conductive sheet. The live wire conductive sheet and the neutral wire conductive sheet can be simultaneously arranged on one side wall of the second insulating plate 203, or respectively arranged on two oppositely arranged side walls. The track slot 101 is provided with two conductive strips 103 corresponding to the elastic conductive sheet 205, specifically a live wire conductive strip 103 and a neutral wire conductive strip 103.

[0041] Among them, Figure 7As shown, the elastic conductive sheet 205 is an arc-shaped protrusion, and the protruding surface of the elastic conductive sheet 205 faces the side of the track slot 101, so that the protruding surface of the elastic conductive sheet 205 can abut against the conductive strip 103. Since the elastic conductive sheet 205 is elastic, when the protruding surface is squeezed by the conductive strip 103, the protruding surface generates a tension on the conductive strip 103, so that the protruding surface is always pressed against the conductive strip 103, maintaining the power-on state, avoiding the phenomenon of power failure due to poor contact, and reducing the user experience.

[0042] Further, such as Figure 8 and Fig. 9 As shown, the track socket 10 includes a shell 104 with a hollow cavity and an insulating track 105. The hollow cavity of the shell 104 is provided with the insulating track 105 along the length direction of the shell 104. The insulating track 105 is used to fix the conductive strips 103 and insulate the conductive strips 103 in pairs to prevent multiple conductive strips 103 from forming a loop with each other and causing a short circuit. The insulating track 105 and the top surface of the hollow cavity form a track slot 101, and the side walls of the insulating track 105 are provided with multiple positioning grooves 106 arranged along the length direction of the insulating track 105 corresponding to the multiple conductive strips 103. The positioning grooves 106 are strip-shaped, and each conductive strip 103 is correspondingly fixed in each positioning groove 106, wherein the positioning grooves 106 are dovetail-shaped, and the radial length of the end of the positioning groove 106 facing the insertion is smaller than the radial length of the other end of the positioning groove 106 away from the plug 20, and the shape of the conductive strip 103 is adapted to the shape of the positioning groove 106, so that the positioning groove 106 can more firmly fix the conductive strip 103, thereby improving the stability of the conductive strip 103.

[0043] The material of the insulating rail 105 can be plastics such as PPS (polyphenylene sulfide), PBT (polybutylene terephthalate fiber), PET (polyterephthalate plastic), etc., which have good insulation properties, prevent users from electric shock, and improve safety in use.

[0044] Furthermore, the track socket 10 further includes a waterproof silicone 30, which is disposed at the socket of the track socket 10. The waterproof silicone 30 is provided with an opening 301 corresponding to the plug 20. Since the waterproof silicone 30 is elastic, when the plug 20 is inserted into the track slot 101 through the opening 301 to be electrically connected to the conductive strip 103, the plug 20 stretches the waterproof silicone 30 so that the plug 20 can be inserted into the track slot 101. When the functional module 212 is removed, the opening 301 of the waterproof silicone 30 is restored to its original position, which can prevent dust and water from entering the track socket 10 and causing a short circuit, thereby improving the safety of the dining car 200.
