[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0024] The technical terms used in the embodiments are explained below:
[0025] An electric actuator, also known as a motorized linear actuator, is an electrically driven device that converts the rotary motion of an electric motor into linear reciprocating motion. In train carriage luggage rack design, the electric actuator serves as the core actuator of the tilting mechanism, achieving automated angle adjustment of the luggage rack brackets through precise linear motion control. The following are the technical details and application advantages of electric actuators in luggage rack design:
[0026] I. Technical Principles and Core Parameters of Electric Linear Actuators:
[0027] Working principle:
[0028] The electric actuator converts rotary motion into linear motion of the lead screw by driving a worm gear or planetary gear reduction mechanism through a built-in motor, thereby pushing the load (such as a U-shaped frame) to achieve rotation.
[0029] In the design of the luggage rack, the telescopic movement of the electric push rod is converted into the tilt angle of the rack. By controlling the stroke of the electric push rod, the tilt angle of the luggage rack can be precisely adjusted.
[0030] Key technical parameters:
[0031] Thrust: The thrust of the electric push rod must be matched with the load of the luggage rack. For example, the thrust of the electric push rod in the design must be ≥1000N to withstand the combined force of a fully loaded suitcase (assuming a total weight ≤80kg) and the weight of the rack itself.
[0032] Stroke: The stroke of the electric actuator determines the tilting range of the bracket. In the design, the electric actuator stroke is 150mm, corresponding to a bracket tilting angle of 30°, which meets ergonomic access requirements.
[0033] Speed: The extension and retraction speed of the electric actuator affects operating efficiency. The design uses an adjustable speed electric actuator, with an unloaded speed of up to 30mm / s and a speed decay rate of less than 20% under full load, ensuring smooth operation.
[0034] Protection level: The electric actuator must meet the IP65 protection standard to resist dust, moisture and vibration impact during train operation.
[0035] II. Advantages of using electric linear actuators in luggage rack design:
[0036] Synchronization control and stability:
[0037] The dual electric actuators are synchronously controlled via a rotary switch and use the CAN bus communication protocol to ensure that the extension and retraction error of the two electric actuators is less than 0.5mm, thus preventing the bracket from tilting and jamming.
[0038] The electric actuator has a built-in position sensor (such as a Hall sensor) that provides real-time feedback of stroke data, forming a closed-loop control. The angle adjustment accuracy reaches ±0.1°, improving operational safety.
[0039] Ease of use and user-friendliness:
[0040] Passengers can trigger the electric push rod by turning a knob switch, eliminating the need to manually move the luggage rack. The operating force is reduced to <5N, making it suitable for passengers of different ages and physical strengths.
[0041] The electric push rod's soft start and stop function (acceleration ≤ 0.5m / s2) reduces mechanical impact, prevents luggage from slipping due to inertia, and improves user comfort.
[0042] Safety redundancy and fault protection:
[0043] The electric actuator has a built-in overload protection module that automatically shuts down when the load exceeds 120% of the rated thrust to prevent the motor from burning out or the structure from being damaged.
[0044] In an emergency, passengers can quickly reset the luggage racks using a manual release mechanism (such as a mechanical clutch) to ensure that evacuation routes remain clear.
[0045] Space optimization and lightweighting:
[0046] The electric actuator features a compact design (40mm in diameter and 300mm in length) and is integrated into the interior of the side wall of the carriage, without taking up passenger space.
[0047] The use of aluminum alloy housing and high-strength plastic gears reduces the weight of the electric actuator to 1.8kg, a 60% reduction compared to traditional hydraulic cylinders, which aligns with the trend of lightweight trains.
[0048] III. Summary:
[0049] As a core component of the train's luggage rack tilting mechanism, the electric actuator significantly improves the convenience and safety of luggage storage and retrieval through its precise linear motion control, synchronous stability, and safety redundancy design. In the future, with breakthroughs in intelligent, lightweight, and energy-efficient technologies, the electric actuator will play an even more crucial role in train interior design, providing passengers with a more comfortable and efficient travel experience.
[0050] Reference Figures 1 to 4 As shown, this utility model provides a luggage rack for a train carriage, including multiple luggage rack brackets installed on the side wall of the carriage. The multiple luggage rack brackets are arranged at equal intervals along the length of the carriage. A flipping mechanism is provided on both sides of the bottom end of the luggage rack bracket. The luggage rack bracket is flipped by the flipping mechanism. The luggage rack bracket includes a U-shaped frame 8. A sliding component is provided between the opposite sides of the opening of the U-shaped frame 8. The luggage box rolls in contact with the sliding component. A tray 3 is detachably connected to the bottom end of the U-shaped frame 8. The tray 3 is located below the sliding component.
[0051] In this embodiment, a rotary switch is installed on the side wall of the carriage. The rotary switch is used to control the synchronous operation of the two flipping mechanisms. For example, rotating the rotary switch clockwise flips the luggage rack bracket downwards, making it easier for passengers to place their suitcases on it. Then, rotating the rotary switch counterclockwise flips the luggage rack bracket upwards, preventing the suitcases from sliding off. In addition, a blocking plate is fixedly connected between the openings of the U-shaped frame 8. This blocking plate is used to intercept the suitcases and prevent them from sliding off and hitting passengers when the luggage rack bracket flips downwards.
[0052] In use, the luggage rack bracket is flipped downwards by the set flipping mechanism. Passengers place their suitcases on the sliding components and then push the suitcases. At the same time, the luggage rack bracket is flipped upwards by controlling the flipping mechanism to prevent the suitcases from sliding out.
[0053] The tray 3 can collect dust that falls from the suitcase, as well as liquids that may be accidentally spilled inside the suitcase, preventing them from falling directly on the passenger's head.
[0054] The flipping mechanism in this invention enables the luggage rack angle to be adjusted, facilitating the quick loading and unloading of large luggage items and effectively preventing luggage from shifting or falling due to inertia during train operation.
[0055] Furthermore, the sliding assembly includes a plurality of rollers 15, which are rotatably connected between opposite sides of the opening of the U-shaped frame 8, with the distance between adjacent rollers 15 being equal.
[0056] With the above setup, when the suitcase is placed or taken out, it will come into contact with these rollers 15. The rolling action reduces friction and makes the operation easier.
[0057] Furthermore, the flipping mechanism includes two sets of hinges, which are symmetrically arranged on both sides of the luggage rack bracket. Each set of hinges includes a second hinge seat 7 and a first hinge seat 1, which are fixedly connected from top to bottom along the side wall of the carriage. The end of the U-shaped frame 8 away from the opening is hinged between the two second hinge seats 7. An electric push rod 2 is hinged on the first hinge seat 1. A sliding member is hinged to the output end of the electric push rod 2. The sliding member is slidably limited and connected to the side of the U-shaped frame 8.
[0058] In this embodiment, the rotary button is electrically connected to both electric actuators 2 simultaneously, enabling simultaneous control of both electric actuators 2.
[0059] By controlling the two electric push rods 2 to extend synchronously, the extended end of the electric push rod 2 pushes the sliding component to slide away from the hinge seat 7. At the same time, the hinge between the electric push rod 2 and the hinge seat 1 rotates, and the luggage rack bracket flips upward. Conversely, by controlling the electric push rod 2 to retract synchronously, the retracted end of the electric push rod 2 drives the sliding component to move closer to the hinge seat 7, and the luggage rack bracket flips downward.
[0060] Furthermore, to ensure the reliability of the sliding component, grooves 9 are provided on both sides of the U-shaped frame 8, and a blocking plate 5 is detachably connected to the side. The blocking plate 5 has an elongated hole 4, which is corresponding to the groove 9. The blocking plate 5 and the groove 9 form a receiving cavity, and the sliding component is limited to sliding within the receiving cavity. The connecting end of the sliding component passes through the elongated hole 4 and is hinged to the output end of the electric push rod 2.
[0061] Furthermore, to improve smoothness, the sliding component includes a slide block 11, on which two sets of pulleys 12 are rotatably connected. One set of pulleys 12 slides in contact with one side wall of the groove 9, and the other set of pulleys 12 slides in contact with the other side wall of the groove 9. The connecting end is a rotating shaft 10 fixedly connected to the middle of the slide block 11. The rotating shaft 10 passes through the elongated hole 4 and is hinged to the output end of the electric push rod 2.
[0062] Furthermore, to prevent wear and tear on the surface of the suitcase, an elastic cushioning layer is fixedly fitted onto the cylinder 15, which can be a rubber sleeve.
[0063] Furthermore, in order to facilitate the disassembly and cleaning of the tray 3, side strips 13 are fixedly connected to both sides of the bottom end of the U-shaped frame 8. Guide grooves 14 are provided on the side strips 13. Flanged edges are provided on both sides of the tray 3, and the folded edges are slidably limited within the guide grooves 14.
[0064] Furthermore, to prevent the suitcase from slipping off the side of the U-shaped frame 8, side panels 6 are connected to both sides of the top of the U-shaped frame 8.
[0065] The working principle of the luggage rack for train carriages provided by this utility model is as follows: After the passenger boards the train, they turn the knob switch, and the two electric push rods 2 shorten simultaneously, causing the U-shaped frame 8 to tilt downwards. The passenger places their suitcase on the pulley 12 and pushes the suitcase into place by hand. Then, they turn the knob switch in the opposite direction, and the two electric push rods 2 extend simultaneously, causing the U-shaped frame 8 to tilt upwards. The passenger then returns to their seat. When the train arrives at the station and the passenger needs to take their suitcase, they only need to repeat the above operation to make the U-shaped frame 8 tilt downwards. The passenger then lets the handle end of the suitcase pass over the barrier plate first, and then pulls out the suitcase. Finally, they turn the knob switch to reset the U-shaped frame 8.
