Description

Technical Field

[0001] This invention relates to the field of washing and grooming technology, and in particular to a vehicle-mounted integrated washing and grooming cabinet and its application in rail transit vehicles. Background Technology

[0002] Washing and grooming mainly includes washing hands, face, arms, and feet. Currently, there are two types of washbasin cabinets with available information, both of which are open structures made of ceramic. One type is a single-basin open structure, similar to a washbasin, where hands, face, and arms are washed using the faucet, and water is collected using a cup or spoon to wash feet. The other type is an open structure with upper and lower basins, similar to two washbasins, where hands, face, and arms are washed using the faucet in the upper basin, and feet are washed using the faucet in the lower basin.

[0003] While the two existing structures can barely meet washing requirements, the open design easily causes water to splash around the cabinet, requiring outdoor use or indoor locations with dedicated cleaning services. The environment inside railway passenger cars does not meet these requirements. Furthermore, the ceramic mounting base is mostly cement or brick walls, which are not available in railway passenger cars. Therefore, the existing washroom cabinets are unsuitable for onboard environments. Currently, no effective solution has been proposed to address these problems. Summary of the Invention

[0004] Purpose of the invention: To provide a vehicle-mounted washroom cabinet and its application in rail transit vehicles, so as to at least solve one of the problems existing in the prior art.

[0005] Technical solution: A vehicle-mounted washbasin cabinet, comprising:

[0006] A single-unit cabinet;

[0007] A washbasin is horizontally positioned on one side of the vertical cabinet.

[0008] A foot basin is rotatably mounted inside the vertical cabinet and located below the washbasin.

[0009] Two-link rotating components are symmetrically arranged on both sides of the foot basin, with one end connected to the foot basin and the other end connected to the vertical cabinet.

[0010] A water supply trigger limiter is disposed on one side of the foot bath at a preset first angle; and

[0011] A water supply component is connected to the inner wall of the vertical cabinet and is located on one side of the foot basin;

[0012] When the two connecting rod rotating components are extended to a preset second angle, the foot basin rotates synchronously and drives the water supply trigger limiter to abut against the water supply component, thereby triggering automatic water supply.

[0013] Preferably, when the connecting rod rotating assembly retracts to the initial angle, the foot bath rotates and closes synchronously, causing the water supply trigger limiter to separate from the water supply assembly, thereby turning off the automatic water supply.

[0014] Preferably, the linkage rotation assembly includes: a first mounting base disposed on the side of the foot bath, a first rotating rod disposed on the first mounting base, a second rotating rod rotatably disposed at the end of the first rotating rod away from the first mounting base, and the end of the second rotating rod away from the first rotating rod being connected to a second mounting base disposed on the vertical cabinet.

[0015] Preferably, the water supply trigger limiter is handle-shaped, and its upper end is connected to an arc-shaped groove on the side of the foot bath. The upper end is rotatable and located at multiple points in the arc-shaped groove so that the angle of the water supply trigger limiter is adjustable.

[0016] Preferably, the water supply component includes: a water supply pipeline disposed in the vertical cabinet, and a push-button water valve for pressing to open and close the water supply pipeline.

[0017] Preferably, the push-button water valve is provided with a lever retaining ring, which cooperates with the water supply trigger limiting component;

[0018] When the lever retaining ring and the water supply trigger limiting component abut against each other, the lever retaining ring applies a pressing force to the push-button water valve to trigger automatic water supply;

[0019] When the lever retainer and the water supply trigger limiter separate, the lever retainer releases the pressing force acting on the push-button water valve to shut off the automatic water supply.

[0020] Preferably, the water supply assembly further includes: a spray shower head connected to the water supply pipeline, the spray shower head being disposed on the vertical cabinet and located above the foot bath;

[0021] When the lever retainer applies pressure to the push-button water valve, the water supply pipeline opens and supplies water to the shower head.

[0022] Preferably, the bottom of the foot bath is also provided with a drain pipe at an angle, and a wastewater collection tank is provided at the bottom of the drain pipe;

[0023] The bottom of the foot bath basin is also provided with several through holes for wastewater to flow to the drain pipe.

[0024] Preferably, the upright cabinet is also equipped with a mirror cabinet, which is located above the washbasin.

[0025] The washbasin is equipped with a sink and a faucet.

[0026] To achieve the above objectives, according to another aspect of this application, a rail transit vehicle is also provided.

[0027] The rail transit vehicle according to this application includes the aforementioned onboard washroom cabinet.

[0028] Beneficial effects: In this embodiment, an automatic water supply method is adopted. When the two connecting rod rotating components are extended to a preset second angle, the foot basin rotates and opens synchronously, causing the water supply trigger limit component to abut against the water supply component, thereby triggering automatic water supply. This achieves the purpose of automatic water supply control when the foot basin is opened and closed, thus realizing the technical effect of washing face, hands, and feet in one unit. This solves the technical problem that open structures easily cause water to splash around the cabinet, requiring its use in outdoor or indoor locations with cleaning services, which is not suitable for the environment inside railway passenger cars. At the same time, the ceramic installation substrate is mostly cement wall or brick wall, which is not available in railway passenger cars. Therefore, the existing wash cabinet is not suitable for the on-board environment. Attached Figure Description

Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0052] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0053] like Figure 1-9 As shown, this application relates to a vehicle-mounted washroom cabinet and its application in rail transit vehicles. Figure 1-4 As shown, the vehicle-mounted washbasin cabinet includes: a vertical cabinet 10; the vertical cabinet 10 refers to the main frame and support structure of the entire device, providing the basis for installing all other components, and defining the overall shape and volume of the device; it can achieve structural stability, making it easy to fix and install in the limited space of a vehicle, and the internal space can be used to store the foot basin 30 and the water system, keeping the exterior clean.

[0054] A washbasin 20 is horizontally positioned on one side of the vertical cabinet 10. The washbasin 20 is horizontally fixed on one side of the vertical cabinet 10, providing a platform for conventional washing (such as washing face, brushing teeth, and washing hands). It can achieve good face and hand washing effects, and at the same time, it integrates basic washing functions to facilitate users' daily cleaning. Its horizontal position is ergonomic and comfortable to use.

[0055] A foot basin 30 is rotatably installed inside the vertical cabinet 10 and located below the washbasin 20; it can realize space reuse, hidden in the cabinet below the washbasin 20, and only unfolded when in use, which greatly saves valuable vehicle interior space; at the same time, it can be folded up when not in use to keep the vehicle interior environment clean and beautiful.

[0056] It is important to know that the foot basin 30 assembly consists of the foot basin 30 body and a counterweight. The counterweight is achieved by adjusting the material of the foot basin 30 body, the material and shape of the internal pedal, and is not a separate component; it can be considered as an integral part of the foot basin 30. The foot basin 30 is a hexahedron with an open top, fixed to the front of a flip-up door panel, and the bottom of the door panel is connected to the cabinet frame via hinges.

[0057] Two-link rotating components 40 are symmetrically arranged on both sides of the foot basin 30, with one end connected to the foot basin 30 and the other end connected to the vertical cabinet 10; this ensures that the foot basin 30 moves smoothly and reliably during unfolding and retraction, without shaking or jamming; it ensures that the foot basin 30 can accurately rotate to the preset use position (unfolded state) and storage position (folded state); its rotation angle directly determines the position of the foot basin 30 and is linked with the water supply trigger mechanism.

[0058] A water supply trigger limiter 50 is positioned on one side of the foot bath 30 at a preset first angle, serving as a mechanical indicator of the foot bath 30's position (i.e., the rotation angle of the connecting rod). When the foot bath 30 rotates with the connecting rod to a specific position (a preset second angle), this component moves to a position where it can contact the water supply assembly 60. The first angle ranges from 50° to 70°. Of course, it can be adjusted according to actual usage needs.

[0059] A water supply component 60 is connected to the inner wall of the vertical cabinet 10 and located on one side of the foot basin 30; it can achieve a good water supply effect and at the same time, it can also achieve a good cooperation effect with the water supply trigger limit component 50.

[0060] When the two connecting rod rotating assemblies 40 are extended to a preset second angle, the foot bath 30 rotates synchronously and opens, causing the water supply trigger limiter 50 to abut against the water supply assembly 60, thereby triggering automatic water supply. The second angle is in the range of 150-170°. Of course, it can be adjusted according to actual usage needs.

[0061] Specifically, when the foot bath 30 is unfolded, the user pulls or rotates the foot bath 30 to make it rotate outward and downward from its vertical storage state (hidden in the cabinet); the linkage rotates, and the rotation of the foot bath 30 drives the linkage rotation components 40 on both sides to move synchronously; when the preset second angle is reached, the user fully unfolds the foot bath 30 to a horizontal (or slightly tilted) position for convenient use.

[0062] When the trigger limiter contacts, the foot bath 30 rotates to this position, and at the same time, the water supply trigger limiter 50 fixed on it (set at the preset first angle) also moves synchronously to the position where it contacts the trigger switch on the water supply assembly 60 and applies pressure (resistance).

[0063] When the automatic water supply is triggered, the pressure or displacement applied by the water supply trigger limiter 50 to the switch / mechanism of the water supply component 60 directly triggers the opening of the water supply component 60, and the water flows out from the outlet (such as a shower head) of the water supply component 60, so the user can start washing their feet.

[0064] When the user finishes washing their feet and rotates the foot bath 30 upwards to retract it, the angle of the linkage assembly decreases, and the water supply trigger limit piece 50 moves away from the water supply assembly 60. The switch / mechanism of the water supply assembly 60 is reset, and the water supply is automatically shut off.

[0065] After use, push the cabinet door back. The water circuit automatically shuts off in the reverse of the opening process described above. The position and weight setting of the foot bath's center of gravity ensure the cabinet door closes completely.

[0066] The water supply to the foot bath 30 in this application is controlled automatically by a fully mechanical system. When using the foot bath 30, simply open the outer door panel of the foot bath 30; water will be supplied automatically once it is fully open, without the need for additional operation of the water supply valve. After use, push the door panel back, and the water supply will automatically stop, and the door panel will automatically close.

[0067] This application applies to the design structure of a washbasin cabinet for in-vehicle environments. The washbasin cabinet is an integrated modular structure that integrates a hand basin, a foot basin, a drain, and a water supply on / off mechanism.

[0068] As can be seen from the above description, this application achieves the following technical effects:

[0069] In this embodiment, an automatic water supply is adopted. When the two connecting rod rotating components 40 are extended to a preset second angle, the foot basin 30 rotates and opens synchronously, causing the water supply trigger limit component 50 to abut against the water supply component 60, thereby triggering automatic water supply. This achieves the purpose of automatically controlling the water supply when the foot basin 30 opens and closes, thus realizing the technical effect of washing face, hands, and feet in one unit. This solves the technical problem that open structures easily cause water to splash around the cabinet, requiring its use in outdoor or indoor locations with cleaning services, which is not suitable for the environment inside railway passenger cars. At the same time, the ceramic installation substrate is mostly cement or brick walls, which are not available in railway passenger cars, so the existing washbasin cabinets are not suitable for the on-board environment.

[0070] Furthermore, when the connecting rod rotating assembly 40 retracts to its initial angle, the foot basin 30 rotates and closes synchronously, causing the water supply trigger limit member 50 to separate from the water supply assembly 60, thereby shutting off the automatic water supply. It is understood that this achieves the effect of automatically shutting off the water supply, thus avoiding water waste and improving structural reliability.

[0071] like Figure 7As shown, the linkage rotation assembly 40 includes: a first mounting base 401 disposed on the side of the foot bath 30; a first rotating rod 402 disposed on the first mounting base 401; a second rotating rod 403 rotatably disposed at the end of the first rotating rod 402 away from the first mounting base 401; and the end of the second rotating rod 403 away from the first rotating rod 402 connected to a second mounting base 404 disposed on the vertical cabinet 10. It can be understood that the dual rotating rod structure achieves a composite rotation trajectory, ensuring that the foot bath 30 is stably suspended in a horizontal position after unfolding, avoiding swaying; simultaneously, the force is distributed and transmitted through two levels of rods, reducing the load on a single hinge point and extending service life (especially suitable for bumpy vehicle environments); and the multi-stage folding allows the foot bath 30 to be completely embedded in the cabinet, minimizing space occupation.

[0072] Furthermore, the water supply trigger limiter 50 is handle-shaped, and its upper end is connected to an arc-shaped groove 301 formed on the side of the foot bath 30. The upper end is rotatably located at multiple points in the arc-shaped groove 301, so that the angle of the water supply trigger limiter 50 is adjustable. It can be understood that by adjusting the position of the water supply trigger limiter 50 in the arc-shaped groove 301, multiple angle adjustments can be achieved, thereby further improving the precision of the fit.

[0073] like Figure 8 As shown, the water supply assembly 60 includes: a water supply pipe 601 disposed within the vertical cabinet 10, and a push-button water valve 602 disposed on the water supply pipe 601 for pressing to open and close the water supply pipe 601. It is understood that the mechanical triggering is reliable, the purely physical structure requires no electricity, making it suitable for vehicle environments (avoiding circuit failures / electromagnetic interference); the instantaneous response, with the lever retaining ring 70 amplifying the displacement of the limiting component, ensures that the valve is triggered with a light touch, reducing the operating force; the failure rate is low, the push-button valve structure is simple, and it is more resistant to humid environments than electronic sensors.

[0074] like Figure 9 As shown, a lever retaining ring 70 is provided on the push-button water valve 602, and the lever retaining ring 70 cooperates with the water supply trigger limiting component 50;

[0075] When the lever retaining ring 70 and the water supply trigger limiting member 50 abut against each other, the lever retaining ring 70 applies a pressing force to the push-button water valve 602 to trigger automatic water supply;

[0076] When the lever retaining ring 70 and the water supply trigger limiter 50 separate, the lever retaining ring 70 releases the pressing force acting on the push-button water valve 602, thereby shutting off the automatic water supply. It is understood that this achieves a good working effect, thus enabling precise control.

[0077] Precise two-way control: gradual pressure is applied during deployment to avoid water hammer impact, and instantaneous separation and rapid water cut-off are achieved during retraction.

[0078] Furthermore, the water supply component 60 also includes a spray shower head 603 connected to the water supply pipe 601, the spray shower head 603 being disposed on the vertical cabinet 10 and located above the foot bath 30;

[0079] Specifically, when the lever retaining ring 70 applies pressure to the push-button water valve 602, the water supply pipe 601 opens and supplies water to the shower head 603. This achieves a good spraying effect, thus ensuring a good foot-washing experience.

[0080] like Figure 5-6 As shown, a drain pipe 80 is also provided at an angle at the bottom of the foot bath 30, and a wastewater collection tank 90 is provided at the bottom of the drain pipe 80;

[0081] The bottom of the foot basin 30 is also provided with several through holes 302 for wastewater to flow into the drain pipe 80. This allows for good wastewater collection while ensuring good wastewater flow, thus preventing water accumulation.

[0082] Preferably, the through holes 302 are distributed around the bottom of the foot bath 30.

[0083] Furthermore, a mirror cabinet 100 is also provided on the vertical cabinet 10, and the mirror cabinet 100 is located above the washbasin 20;

[0084] The washbasin 20 is equipped with a sink and a faucet. Understandably, this provides multiple functions, thereby enhancing its practicality.

[0085] The working principle of this application is as follows:

[0086] When the foot bath 30 is in use, it is opened by the cabinet door handle. The foot bath 30 flips outward along with the cabinet door, causing relative movement of the linkage device. The water supply trigger limiter 50 gradually approaches the lever retaining ring 70. During the flipping process, the center of gravity of the foot bath 30 continuously changes. When the foot bath 30 is opened to the set angle, the water supply trigger limiter 50 contacts the lever retaining ring 70. At this time, the position and weight of the foot bath 30's center of gravity are set so that the water supply trigger limiter 50 can slide into the lever. When the flipping action stops in the annular groove of the retaining ring 70, the foot basin 30 is limited, which can prevent the foot basin 30 from shaking during vehicle operation; during the process of the water supply trigger limit piece 50 sliding into the lever retaining ring 70, the lever mechanism of the lever retaining ring 70 has relative movement, and the force point is applied to the valve cover of the push-type water valve 602. The valve cover is gradually pressed and water supply begins. After the water supply trigger limit piece 50 slides completely into the lever retaining ring 70, the valve cover is pressed into place, the water valve is fully opened, and water supply is realized.

[0087] This application also relates to a rail transit vehicle, including the aforementioned vehicle-mounted washroom cabinet.

[0088] This application also has the following beneficial effects:

[0089] I. Maximizing Space Utilization:

[0090] The washbasin 20 and foot basin 30 are designed to be stacked vertically (the foot basin 30 is hidden under the washbasin 20); the foot basin 30 can be rotated for storage, unfolded when in use, and completely hidden in the cabinet when not in use.

[0091] II. Functional Integration and Separation:

[0092] The two main functions of washing (face / hands) and washing feet are integrated into a compact cabinet; at the same time, the separate foot basin 30 achieves dry and wet separation and hygiene separation, avoiding cross-use.

[0093] III. Highly convenient and automated operation:

[0094] With a single touch, water flows immediately upon unfolding. Users only need to perform one action (unfolding the foot bath basin 30) to automatically trigger water supply. This eliminates the need to turn on the tap, making operation even smoother, especially in a cramped car.

[0095] Water shuts off automatically when the foot bath basin is retracted: The water supply is automatically shut off simultaneously with the 30-second retraction of the basin, preventing waste or water accumulation caused by forgetting to turn off the water.

[0096] Fourth, it saves time and effort: it simplifies the preparation process for washing feet and improves the user experience.

[0097] V. Stable and reliable structure:

[0098] The symmetrically designed linkage rotation assembly 40 ensures stable support for the foot bath 30 after it is unfolded, ensuring safe use; it also provides precise rotation trajectory and positioning.

[0099] VI. Keep the environment clean:

[0100] The foot basin 30 and water supply components 60 are hidden inside the cabinet, making the appearance neat and not affecting the aesthetics of the vehicle interior; the linked water supply mechanism reduces the risk of water splashing to the surroundings (compared to manual switches).

[0101] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
