Description

Technical Field

[0001] This utility model relates to the field of safety protection technology, and in particular to a seat inlet protection device and a high-speed train. Background Technology

[0002] In the current seat design of high-speed trains, the power cables are typically routed through the seat from below or behind it to a socket or other electrical equipment on the seat. There is a gap between the seat base and the carriage floor, leaving exposed portions of the power cables. These exposed cables are easily touched or pulled during passenger luggage placement or staff cleaning, potentially causing damage or short circuits and posing a safety hazard.

[0003] In existing technologies, the following measures can be taken to protect power cords: encasing the power cord in a protective shell to reduce direct contact between the power cord and the external environment; or placing the power cord within a cable tray, with clips engaging with the tray to prevent loosening or detachment. While these methods can provide some protection, several problems remain. For example, protective shells are difficult to install in the gap between the seat base and the vehicle floor; if the shell is not securely installed, it can still be susceptible to displacement or loosening due to external impacts. Furthermore, with protective structures consisting of cable trays and clips, the clips may loosen or age over time, allowing the power cord to easily detach from the tray and affecting the protective performance.

[0021] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0023] Example 1: Because there is a certain gap between the seat base 2 and the carriage floor 1 in some existing high-speed trains, the power cord will be exposed in the gap. When passengers push luggage under the seat or when staff clean, the luggage or tools may come into contact with the power cord, causing the power cord to be pulled and damaged, which may render the socket 3 unusable.

[0024] Based on this, this embodiment provides a seat cable inlet protection device. Figure 1 This is an installation diagram of a seat cable protection device provided in an embodiment of this application. Figure 2 This is a schematic diagram of the structure of a seat cable protection device provided in an embodiment of this application, as an example, such as... Figure 1 and Figure 2 As shown, the seat cable protection device includes a protective sleeve 5 and a connector 4. The connector 4 is used to cooperate with the car floor 1. The power cable under the car floor 1 passes through the connector 4 and the protective sleeve 5 in sequence.

[0025] The protective sleeve 5 serves as a protective component for the power cord. Its overall cylindrical shape facilitates compatibility with the power cord and avoids potential safety hazards due to sharp edges or other structural features. The height of the protective sleeve 5 is determined based on the gap between the seat base 2 and the vehicle floor 1. The inner diameter of the protective sleeve 5 is set according to the size of the power cord to ensure minimal space between the power cord and the inner wall of the protective sleeve 5, preventing the power cord from swaying relative to the sleeve.

[0026] To facilitate the assembly and disassembly of the protective sleeve 5, the protective sleeve 5 is configured as a split structure in the solution provided in this application embodiment. Figure 3 This is a schematic diagram of the protective sleeve 5 provided in the embodiments of this application, as shown below. Figure 2 and Figure 3 As shown, the protective sleeve 5 includes two protective plates 9. The cross-section of the protective plates 9 is arc-shaped and nearly semi-circular, so that the two protective plates 9 cooperate to form a protective cavity for the power cord. One end of the two protective plates 9 is hinged, and the other end is engaged through an opening and closing structure, so that the two protective plates 9 can be opened and closed, making it convenient to install on the outside of the power cord.

[0027] As an example, the opening and closing structure can be implemented using a plug-in structure or an adsorption structure. When using a plug-in structure, one end face of the protective plate 9 has a protrusion, and the corresponding end face of the other protective plate 9 has a groove. The protective sleeve 5 can be opened and closed simply by plugging and unplugging. When using an adsorption structure, one end face of the protective plate 9 is fixed with a magnet 11, and the corresponding end face of the other protective plate 9 is fitted with a metal sheet (if the protective sleeve 5 is made of metal, the metal sheet is not required). Adsorption and fixation are achieved through magnetic attraction; alternatively, a vacuum suction cup can be used instead of the magnet 11, where the vacuum suction cup adheres to the end face of the opposite protective plate 9 under pressure.

[0028] The protective sleeve 5 and the connecting seat 4 are detachably connected. As an example, the two are plugged in and the protective sleeve 5 is installed on the carriage floor 1 by setting the connecting seat 4. As a connecting component, the connecting seat 4 can prevent the protective sleeve 5 from tipping over or tilting, and prevent the power cord from being pulled, thus further ensuring the safety of the power cord.

[0029] Figure 4 This is a schematic diagram of the connector 4 structure provided in the embodiment of this application, combined with... Figure 3 and Figure 4As shown, the bottom of the protective plate 9 is provided with multiple protrusions 10 at intervals, and the upper surface of the connecting seat 4 is provided with multiple insertion holes 7, with each insertion hole 7 corresponding to one of the protrusions 10. The protective sleeve 5 and the connecting seat 4 can be installed by inserting the protrusions 10 into the insertion holes 7. Of course, in other embodiments, the positions of the protrusions 10 and the insertion holes 7 can be adjusted, with the protrusions 10 located on the upper surface of the connecting seat 4 and the insertion holes 7 located on the bottom surface of the protective plate 9.

[0030] The protrusion 10 can be cylindrical, cuboid, or other shapes, depending on the actual situation; the cross-sectional shape of the insertion hole 7 is adapted to the cross-section of the protrusion 10. In the solution provided in this application embodiment, two protrusions 10 are provided at the bottom of the protective plate 9, and four insertion holes 7 are opened on the upper surface of the connecting seat 4; of course, in other embodiments, the number of protrusions 10 and insertion holes 7 can be adjusted according to the installation requirements.

[0031] To facilitate opening the engaged protective sleeve 5, or to facilitate separating the protective sleeve 5 and the connecting seat 4, such as Figure 2 and Figure 3 As shown, a through groove 8 is provided on the side of the protective plate 9. The operator can open the two protective plates 9 by inserting their hand into the through groove 8 and applying outward force. By inserting their hand into the through groove 8 and lifting the protective plate 9 upward, the protective sleeve 5 can be disengaged from the connecting seat 4. Similarly, applying downward force can achieve quick engagement between the protective sleeve 5 and the connecting seat 4. In the solution provided in this application embodiment, a limiting part 12 is also provided on the top surface of the through groove 8. The two ends of the limiting part 12 are arc surfaces, which facilitates hand gripping and thus facilitates the disassembly and assembly of the seat inlet protection device.

[0032] The shape of the connector 4 can be set according to actual requirements. In the solution provided in this application embodiment, the connector 4 is a rectangular parallelepiped structure, which is convenient for manufacturing. Figure 4 As shown, the connector 4 has a through-hole 6 in the thickness direction, and insertion holes 7 are distributed around the cable routing hole 6. The cable routing hole 6 is used for the power cable to pass through the underside of the carriage floor 1. In use, first lead the power cable out through the cable routing hole 6, then fasten the open protective sleeve 5 to the outside of the power cable near the connector 4, and then insert the protective sleeve 5 into the connector 4.

[0033] The solution provided in this application embodiment consists of a detachable protective sleeve 5 and a connecting seat 4. The protective sleeve 5 adopts a split structure formed by two protective plates 9, and the connecting seat 4 can cooperate with the vehicle floor 1. The cooperation between the connecting seat 4 and the protective sleeve 5 makes the protective sleeve 5 firmly installed in the gap between the seat base 2 and the vehicle floor 1, thereby achieving the purpose of effectively protecting the power line.

[0034] In the solution provided in this application embodiment, two protective plates 9 are rotatably connected at one end and engaged through an opening and closing structure at the other end, enabling quick opening or closing. The through groove 8 design on the side of the protective plate 9 facilitates manual opening and closing of the protective sleeve 5 by the operator, and also facilitates the insertion or disengagement of the protective sleeve 5 and the connecting seat 4, improving the efficiency and convenience of installation and disassembly. In addition, the protective sleeve 5 and the connecting seat 4 adopt an insertion engagement method, which can be quickly connected or disconnected, facilitating maintenance.

[0035] Example 2: This embodiment provides a high-speed train, such as Figure 1 As shown, the train set is equipped with multiple seats. A socket 3 is installed on one side of the seat base 2. The seat cable protection device described in Embodiment 1 is installed on the carriage floor 1 corresponding to the socket 3. A power cable is laid on the underside of the carriage floor 1. One end of the power cable passes through the cable hole 6 of the connector 4 and the protective sleeve 5 and extends into the interior of the seat base 2. The power cable is electrically connected to the socket 3.

[0036] In the solution provided in this application embodiment, the carriage floor 1 is provided with a slot adapted to the connecting seat 4. The top surface of the connecting seat 4 is flush with the upper surface of the carriage floor 1, so that the protective sleeve 5 protrudes from the upper surface of the carriage floor 1. The protective sleeve 5 is located in the gap between the seat base 2 and the carriage floor 1. The protective sleeve 5 protects the power cord and prevents the power cord from being damaged by external factors. The connecting seat 4 can be locked and fixed to the carriage floor 1 with bolts.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
