Technical Field

[0001] This utility model belongs to the field of train door manufacturing technology, specifically a turning guide rail for high-speed rail doors. Background Technology

[0002] In related technologies, the sliding doors of high-speed train carriages are restricted and guided by guide rails during operation. A drive device applies pushing and pulling force to the sliding door, causing it to move along the guide rails and thus opening and closing. However, in winter, condensation outside the carriage causes ice to easily form inside the guide rails, affecting the door's movement. Existing technologies cannot effectively prevent this phenomenon. Utility Model Content

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing embodiments of the present invention, cross-sectional views of device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0025] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a turning guide rail for a high-speed rail door, including a component 1 and a jet assembly 2. The component 1 is used to be installed on the carriage, wherein:

[0026] The component 1 is provided with a guide groove 3 for guiding purposes;

[0027] The jet assembly 2 is used to jet hot fluid into the guide channel 3 at one end of the guide channel 3. The hot fluid can be a liquid with temperature, such as hot water, or it can be hot air.

[0028] During installation, this utility model is achieved by connecting a sliding part 4 to the carriage door, which slides in conjunction with the guide groove 3. By spraying hot fluid into the guide groove 3, the hot fluid diffuses continuously along the length of the guide groove 3, thus providing insulation or heating to the inner wall of the guide groove 3. This helps prevent ice formation inside the guide groove 3 to a certain extent. Alternatively, even if ice forms inside the guide groove 3, the hot fluid can heat the ice, promoting its melting. Therefore, the guide rail provided by this utility model can effectively prevent ice formation, ensuring the normal sliding of the carriage door.

[0029] Furthermore, refer to Figure 2 and Figure 5The jet assembly 2 includes an inlet channel connected to one end of the guide groove 3, and an extraction element 201 and a heating element 202 disposed in the inlet channel. The extraction element 201 is used to extract fluid, thereby sending the fluid into the guide groove 3, and the fluid is heated by the heating element 202.

[0030] Furthermore, refer to Figure 5 The extraction element 201 can be a fan, which can draw outside air into the guide groove 3 to achieve the effect of extracting fluid.

[0031] Furthermore, refer to Figure 5 The entry channel includes a first section 203 and a second section 204. The inner diameter of the first section 203 is larger than that of the second section 204. The second section 204 is connected to the guide groove 3. The extraction element 201 is disposed in the first section 203. When external air is drawn into the first section 203, the flow rate of the fluid increases as it enters the second section 204 due to the smaller diameter, thereby increasing the diffusion effect of the fluid. The heating element 202 is disposed in the second section 204, which can further compress the space inside the second section 204, thereby increasing the fluid speed.

[0032] Furthermore, refer to Figure 3 The guide groove 3 includes an inner cavity 301 and an opening 302. The width of the opening 302 is smaller than the width of the inner cavity 301. The second segment 204 is connected to the inner cavity 301. After the fluid enters the inner cavity 301, it gradually diffuses out from the opening 302, thereby increasing the effect of the fluid on various parts of the inner cavity 301.

[0033] Furthermore, refer to Figure 2 and Figure 4 Regarding the structure of the sliding part 4, it includes a connecting end 401 and a plurality of rollers 402 rotatably disposed on the connecting end 401. The connecting end 401 is used to connect to the carriage door. The plurality of rollers 402 respectively roll and cooperate with the two side walls of the inner cavity 301, so that the connecting end 401 can move along the path direction of the guide groove 3, and a gap 403 is formed between the plurality of rollers 402. The gap 403 can be used for gas to pass through. This structural design of the sliding part 4 can reduce the impact on the fluid flow process.

[0034] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
