Description

Technical Field

[0001] This application relates to the field of rail transit technology, and in particular to a coupling chute device and a rail vehicle. Background Technology

[0002] Currently, high-speed trains have a wide demand for chute installation in terms of components (such as interior parts like seats).

[0003] In scenarios where large, heavy objects are attached to chutes, operators often need to repeatedly move the objects to find a suitable installation position. When the attached components are heavy, this process becomes increasingly inconvenient and difficult. Furthermore, during train operation, significant swaying can cause components attached to the chutes to slip, necessitating the use of auxiliary connection methods to ensure stable positioning. This undoubtedly increases the overall cost and time required for the installation process. Utility Model Content

[0004] The purpose of this application is to provide a mounting chute device and a rail vehicle, which solves the problems of time-consuming and costly current methods for ensuring stable positioning of mounting components.

[0005] To achieve the above objectives, this application provides a mounting chute device, comprising:

[0006] The mounting housing includes a first mounting part and a second mounting part, which are spaced apart in a first direction to form a groove for the mounting member to slide along a second direction perpendicular to the first direction. The first mounting part is provided with a first positioning hole.

[0007] The first positioning block is movably embedded in the first hook part and is used to move relative to the first hook part along the first direction;

[0008] The second positioning block is movably embedded in the second hook part and is used to move relative to the second hook part in the first direction. The second positioning block is provided with a second positioning hole.

[0009] The linkage mechanism, located inside the mounting housing, is used to connect the first positioning block and the second positioning block. After the mounting piece slides to the first positioning hole, the first positioning block drives the second positioning block to move through the linkage mechanism, so that the mounting piece is locked in the first positioning hole and the second positioning hole.

[0010] In some embodiments, the linkage mechanism includes a first link, a second link, and a third link. The first link and the second link are both rotatably connected to the inside of the mounting housing. The two ends of the first link are rotatably connected to the first positioning block and the first end of the third link, respectively. The two ends of the second link are rotatably connected to the second positioning block and the second end of the third link, respectively.

[0011] In some embodiments, the mounting housing further includes a third mounting plate, the inner wall of which is provided with a slide rail, and the third link slides in cooperation with the slide rail so that the third link slides along a first direction.

[0012] In some embodiments, the mounting housing further includes a first mounting plate and a second mounting plate, wherein the first mounting plate is disposed between the end of the first mounting portion away from the slide groove and the first end of the third mounting plate, and the second mounting plate is disposed between the end of the second mounting portion away from the slide groove and the second end of the third mounting plate;

[0013] The inner wall of the first mounting plate is provided with a first hinge support, and the first connecting rod is hinged to the first hinge support. The inner wall of the second mounting plate is provided with a second hinge support, and the second connecting rod is hinged to the second hinge support.

[0014] In some embodiments, the first positioning block has a first position and a second position. When the first positioning block is in the first position, the end face of the first positioning block near the slide groove is flush with the end face of the first hook part near the slide groove. When the first positioning block is in the second position, the end face of the first positioning block near the slide groove is flush with the lowest position of the first positioning hole.

[0015] In some embodiments, the mounting slide device further includes an elastic element that abuts against the first positioning block and the mounting housing. The elastic element is used to provide an elastic force to the first positioning block so that the first positioning block tends to move from the second position to the first position.

[0016] In some embodiments, the first hook-up portion is provided with a first limiting groove, and the first positioning block is installed in the first limiting groove; the second hook-up portion is provided with a second limiting groove, and the second positioning block is installed in the second limiting groove.

[0017] In some embodiments, the first hook-up portion has a first U-shaped structure at one end near the slide groove, and a first limiting groove is provided in the first U-shaped structure; the second hook-up portion has a second U-shaped structure at one end near the slide groove, and a second limiting groove is provided in the second U-shaped structure.

[0018] In some embodiments, both the first positioning hole and the second positioning hole are semi-circular holes for positioning cylindrical hooks.

[0019] This application also provides a rail vehicle, including a carriage and a coupling chute device as described in any of the preceding claims, disposed inside the carriage.

[0020] Compared to the aforementioned background technology, the mounting slide device provided in this application includes a mounting housing, a first positioning block, a second positioning block, and a linkage mechanism. The mounting housing includes a first mounting portion and a second mounting portion, which are spaced apart in a first direction to form a slide that allows the mounting element to slide along a second direction. The first mounting portion has a pre-drilled first positioning hole. The first positioning block and the second positioning block are respectively embedded in the first mounting portion and the second mounting portion, and are movable along the first direction. The second positioning block has a pre-drilled second positioning hole. The linkage mechanism is built into the mounting housing and connects the first positioning block and the second positioning block.

[0021] In this way, the hanger slides along the groove. When the hanger slides to the first positioning hole, it presses down the first positioning block under the action of gravity. The first positioning block drives the second positioning block to move through the linkage mechanism, so as to realize the stable engagement of the hanger between the first and second positioning holes.

[0022] The beneficial effects of this type of hanging slide device mainly include:

[0023] Firstly, after the hanger slides to the first positioning hole, the first positioning block drives the second positioning block to move through the linkage mechanism, so that the hanger is automatically locked in the first positioning hole and the second positioning hole. This eliminates the need for manual repeated movement of heavy objects to find the installation position, significantly reducing the difficulty of operation and saving time and labor costs during the installation process.

[0024] Secondly, the coupling is securely engaged between the first positioning hole and the second positioning hole, which can effectively prevent the coupling from sliding on the slide even when the train is shaking, thus avoiding potential safety risks caused by component slippage and ensuring the stability of the train during operation.

[0025] Third, the device's precise positioning function reduces reliance on other auxiliary connection methods, lowers material and time costs during installation, improves the efficiency of the entire installation process, and thus reduces the overall cost of installing high-speed train components.

[0026] Fourth, the ingenious combination of the mounting shell, positioning block, and linkage mechanism makes the entire device compact. The synergistic effect between the components improves the reliability of the device, reduces maintenance costs and failure risks caused by loose or damaged components, and extends the service life of the device.

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] It should be noted that the directional terms such as "upper end," "lower end," "left side," and "right side" mentioned below are defined based on the accompanying drawings in the instruction manual.

[0040] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the hanging slide device in the embodiments of this application; Figure 2 This is a structural schematic diagram of the hanging slide device from another angle in an embodiment of this application.

[0041] The mounting slide device provided in this application includes a mounting housing 10, a first positioning block 20, a second positioning block 30, and a linkage mechanism 40.

[0042] The mounting housing 10 includes a first mounting portion 11 and a second mounting portion 12. The first mounting portion 11 and the second mounting portion 12 are spaced apart in a first direction to form a groove 16 for the mounting member 60 to slide along a second direction perpendicular to the first direction. The first mounting portion 11 is provided with a first positioning hole 113, and the second mounting portion 12 may also be provided with another positioning hole opposite to the first positioning hole 113. The first direction may be as follows: Figure 1 The Y-axis direction is shown, and the second direction can be as follows: Figure 1 The X-axis direction is shown.

[0043] The first positioning block 20 is movably embedded in the first hook-up portion 11, and the first positioning block 20 is used to move relative to the first hook-up portion 11 along a first direction. The second positioning block 30 is movably embedded in the second hook-up portion 12, and the second positioning block 30 is used to move relative to the second hook-up portion 12 along a first direction. The second positioning block 30 is provided with a second positioning hole 31.

[0044] The linkage mechanism 40 is located inside the mounting housing 10 and is used to connect the first positioning block 20 and the second positioning block 30. After the mounting piece 60 slides to the first positioning hole 113, the first positioning block 20 drives the second positioning block 30 to move through the linkage mechanism 40, so that the mounting piece 60 is engaged in the first positioning hole 113 and the second positioning hole 31.

[0045] In other words, when the hanger 60 is fully embedded in the first positioning hole 113, the second positioning block 30 moves into place and completely locks the hanger 60, thus achieving self-locking positioning of the hanger 60.

[0046] The hanging slide device involved in this application can bring the following beneficial effects:

[0047] Improved ease of operation: After the hanger 60 slides to the first positioning hole 113, the first positioning block 20 drives the second positioning block 30 to move through the linkage mechanism 40, so that the hanger 60 is automatically locked in the first positioning hole 113 and the second positioning hole 31. There is no need for manual repeated movement of heavy objects to find the installation position, which significantly reduces the difficulty of operation and saves time and labor costs in the installation process.

[0048] Enhanced stability: The coupling 60 is securely engaged between the first positioning hole 113 and the second positioning hole 31. Even if the train shakes during operation, it can effectively prevent the coupling component from sliding on the slide groove 16, avoiding potential safety risks caused by component sliding and ensuring the stability of the train during operation.

[0049] Cost reduction: The device's precise positioning function reduces reliance on other auxiliary connection methods, lowers material and time costs during installation, improves the efficiency of the entire installation process, and thus reduces the overall cost of installing high-speed train components.

[0050] Compact structure and high reliability: The ingenious cooperation of the mounting housing 10, positioning block and linkage mechanism 40 makes the whole device compact. The synergistic effect between the components improves the reliability of the device, reduces maintenance costs and failure risks caused by loose or damaged components, and extends the service life of the device.

[0051] In some embodiments, the linkage 40 is specifically a three-bar linkage.

[0052] Specifically, the linkage mechanism 40 includes a first link 41, a second link 42, and a third link 43. Both the first link 41 and the second link 42 are rotatably connected to the interior of the mounting housing 10. The two ends of the first link 41 are rotatably connected to the bottom end of the first positioning block 20 and the first end of the third link 43, respectively (e.g., ...). Figure 1 The bottom end of the second link 42 is rotatably connected to the top end of the second positioning block 30 and the second end of the third link 43 (as shown in the bottom end). Figure 1 (The top shown).

[0053] To facilitate the sliding of the third link 43, the mounting housing 10 also includes a third mounting plate 15. The inner wall of the third mounting plate 15 is provided with a slide rail 151. The third link 43 slides in conjunction with the slide rail 151 so that the third link 43 slides along the first direction.

[0054] Meanwhile, the mounting housing 10 also includes a first mounting plate 13 and a second mounting plate 14. The first mounting plate 13 is located at the end of the first mounting portion 11 away from the slide groove 16 and at the first end of the third mounting plate 15 (e.g., Figure 1 Between the bottom ends shown, the second mounting plate 14 is located at the end of the second hook part 12 away from the slide groove 16 and the second end of the third mounting plate 15 (as shown). Figure 1 Between the tops shown; the inner wall of the first mounting plate 13 is provided with a first hinge support 131, the middle part of the first connecting rod 41 is hinged to the first hinge support 131, the inner wall of the second mounting plate 14 is provided with a second hinge support 141, and the middle part of the second connecting rod 42 is hinged to the second hinge support 141.

[0055] In this way, the hanger 60 slides along the slide groove 16. When the hanger 60 slides to the first positioning hole 113, it presses down the first positioning block 20 under the action of gravity. The first positioning block 20 drives the second positioning block 30 to move downward through the linkage mechanism 40, so as to realize the stable engagement of the hanger 60 between the first and second positioning holes 31.

[0056] In some embodiments, the first positioning hole 113 and the second positioning hole 31 are both semi-circular holes to position the cylindrical hanger 60.

[0057] In other words, for the cylindrical hanger 60, both the first positioning hole 113 and the second positioning hole 31 are semi-circular holes. In this way, the two semi-circular holes can be connected to achieve a stable snap-fit ​​for the hanger 60.

[0058] It should be noted that the first positioning block 20 has a first position and a second position. When the first positioning block 20 is in the first position, the end face of the first positioning block 20 near the slide groove 16 is flush with the end face of the first hook part 11 near the slide groove 16. When the first positioning block 20 is in the second position, the end face of the first positioning block 20 near the slide groove 16 is flush with the lowest position of the first positioning hole 113.

[0059] Alternatively, the distance between the second position and the first position in the first direction is the radius of the first positioning hole 113, or the travel distance of the first positioning block 20 in the first direction is the radius of the first positioning hole 113.

[0060] To facilitate the resetting of the first positioning block 20, the hooking slide device also includes an elastic element 50. The elastic element 50 abuts between the first positioning block 20 and the hooking housing 10. The elastic element 50 is used to provide elastic force to the first positioning block 20 so that the first positioning block 20 has a tendency to move from the second position to the first position.

[0061] The aforementioned elastic element 50 can be two compression springs, which are placed side by side between the first positioning block 20 and the first mounting plate 13. In this way, when the hook 60 slides to the first positioning hole 113, the first positioning block 20 is pressed down under the action of gravity. At this time, the compression spring is in a compressed state. The first positioning block 20 drives the second positioning block 30 to move downward through the linkage mechanism 40, so as to realize the stable engagement of the hook 60 between the two positioning holes. After the hook 60 is disengaged from the first positioning hole 113, the first positioning block 20 is reset under the action of the compression spring, and the second positioning block 30 is also reset under the linkage action of the linkage mechanism 40.

[0062] To facilitate the limiting of the first positioning block 20, the first hook part 11 is provided with a first limiting groove 112, and the first positioning block 20 is installed in the first limiting groove 112. The size and shape of the first limiting groove 112 are adapted to the size and shape of the first positioning block 20 so that the first positioning block 20 can move in the first limiting groove 112 along the first direction. The second hook part 12 is provided with a second limiting groove 122, and the second positioning block 30 is installed in the second limiting groove 122. The size and shape of the second limiting groove 122 are adapted to the size and shape of the second positioning block 30 so that the second positioning block 30 can move in the second limiting groove 122 along the first direction.

[0063] In some embodiments, the first hook-on portion 11 is provided with a first U-shaped structure 111 at one end near the slide groove 16, and a first limiting groove 112 is provided in the first U-shaped structure 111. The second hook-on portion 12 is provided with a second U-shaped structure 121 at one end near the slide groove 16, and a second limiting groove 122 is provided in the second U-shaped structure 121.

[0064] The rail vehicle provided in this application includes a carriage and a coupling chute device, as described in the above specific embodiments, disposed inside the carriage; other parts of the rail vehicle can be referred to in related technologies, and will not be elaborated here.

[0065] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0066] The foregoing has provided a detailed description of the coupling chute device and rail vehicle provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the solution and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of this application.
