Description

Technical Field

[0001] This utility model relates to the field of intelligent logistics equipment technology, specifically to a sliding door suitable for the driver's cab. Background Technology

[0002] In the field of air logistics, the longitudinal transfer vehicle (TV) is the core storage and retrieval equipment in the ULD (Unit Load Device) transfer and storage area. Its function is to remove ULDs from the racks and transport them longitudinally to other storage locations or docking equipment (such as hoists). The TV cab serves as the space for operators to control the operation of the equipment. It needs to be equipped with electrical control cabinets, air conditioning, seats, and other devices. The driver monitors the speed, position, and other parameters of the equipment through the electrical control cabinet and executes control commands.

[0003] In recent years, the rapid development of the logistics industry has placed higher demands on equipment space utilization. In airport logistics scenarios, TVs need to complete efficient transfer of ULDs within a limited space. Therefore, the structural design of the cab must minimize space occupation while meeting functional requirements. Traditional TV cab doors mostly use hinge installation, and their opening and closing depends on the rotation space of the hinge axis. If there are obstacles (such as shelves or other equipment) in this space, they will block the normal opening and closing of the door, making it difficult for the equipment to meet design requirements under space-constrained conditions. In addition, there is an unavoidable structural gap between the traditional door and the cab door frame, which allows dust and debris to enter the cab, reducing air quality and affecting the working environment of operators and the service life of equipment electrical control components.

[0004] In existing technologies, the spatial limitations and insufficient sealing of hinged door structures have become key issues restricting the compact and intelligent development of TV equipment. Therefore, there is an urgent need for a cab door structure that can reduce space requirements and improve dustproof performance to meet the requirements of modern logistics equipment for space efficiency and environmental adaptability. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a sliding door suitable for the driver's cab.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A sliding door suitable for a driver's cab includes a door body, a sliding assembly, and a dustproof brush. The sliding assembly includes a slide rail mounted on the top of the driver's cab via a bracket and a pulley mounted on the top of the door body. The pulley slides in cooperation with the slide rail to enable the door body to perform linear reciprocating motion along the slide rail. The dustproof brush is disposed on the side of the door body and fits against the gap between the door body and the driver's cab.

[0008] Furthermore, buffer stops are provided at both ends of the slide rail.

[0009] Furthermore, it also includes a guide block, which is fixed to the door frame of the cab by a first bolt, and the guide block is used in conjunction with the door body.

[0010] Furthermore, the dustproof brush is fixed to the door frame of the cab by a second bolt, and the bristles of the dustproof brush are closely attached to the side of the door.

[0011] Furthermore, the slide rail and the bracket are fixedly connected by a third bolt.

[0012] Furthermore, the bracket is secured to the top of the cab by a fourth bolt.

[0013] Furthermore, the pulley is fixed to the door body by a fifth bolt, and the pulley slides within the groove of the slide rail.

[0014] Furthermore, the door is equipped with a door handle, a door lock, and glass.

[0015] Compared with existing technologies, the advantages of this utility model are as follows: By adopting a combined installation structure of top slide rail and pulley, the traditional hinged door's rotating opening and closing method is eliminated, eliminating the need to reserve space for hinge axis rotation and avoiding installation limitations caused by obstacles. Compared with traditional structures, this application reduces the lateral space occupied by the TV cab, making it particularly suitable for airport logistics scenarios with narrow aisles and dense equipment, providing feasibility for the compact design of ULD transfer equipment. The dustproof brushes on the side of the door form a dynamic sealing barrier by tightly fitting the gap between the door and the cab with elastic bristles, effectively preventing outdoor dust and debris from entering the cab, ensuring a clean operating environment for equipment such as electrical control cabinets and air conditioners, while improving the air quality in the driver's workspace and reducing equipment maintenance frequency and labor costs. In addition, the buffer door stops at both ends of the slide rail can precisely limit the door's travel, avoiding impact damage during opening and closing. The guide block and slide rail's cooperative guiding design ensure that the door remains stable during sliding, reducing the amplitude of swaying, extending the service life of components such as pulleys and slide rails, and improving the overall reliability of the equipment.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] See appendix Figures 1-4As shown. This application discloses a sliding door suitable for a driver's cab, comprising a door body 1, a sliding assembly 2, and a dustproof brush 3. A door handle 11, a door lock 12, and glass 13 are fixedly installed on the door body 1. Preferably, the door body 1 adopts an aluminum alloy or steel frame structure, with a lightweight sheet material covering the surface for easy sliding operation. Preferably, the door handle 11 is made of L-shaped stainless steel and is located in the middle of the outer side of the door body, with an ergonomically designed grip. Preferably, the door lock 12 can be a mechanical lock or an electromagnetic lock; the mechanical lock has a keyhole, and the electromagnetic lock is electrically connected to a TV electronic control system, supporting remote unlocking. Preferably, the glass 13 is thick tempered glass, embedded in the frame of the door body 1, which not only has good light transmission, allowing the driver to observe the external environment at any time, but also has high strength and impact resistance, effectively ensuring the safety of personnel inside the driver's cab. The sliding assembly 2 includes a slide rail 22 mounted on the top of the cab via a bracket 21 and a pulley 23 mounted on the top of the door 1. The pulley 23 slides in conjunction with the slide rail 22 to enable the door 1 to reciprocate linearly along the slide rail 22. The bracket 21 is the connecting hub between the entire sliding assembly 2 and the top of the cab. It is securely mounted on the top of the cab using high-strength bolts or welding, providing a stable support foundation for the slide rail 22. The bracket 21 is typically made of high-strength aluminum alloy or steel, ensuring sufficient strength and rigidity while reducing its own weight to avoid excessive load on the top of the cab. The slide rail 22 is a key guiding component of the sliding assembly 2. The length of the slide rail 22 is customized according to the width of the cab door frame, and its cross-section is a T-shaped or C-shaped groove. In addition, a lubrication groove is specially provided on the inner wall of the groove of the slide rail 22. Long-lasting grease is injected into the groove, which greatly reduces the friction between the pulley 23 and the slide rail 22, reduces operating noise, and significantly extends the service life of both. Preferably, buffer door stops 24 are welded to both ends of the slide rail 22. The buffer door stops 24 are made of polyurethane, which can absorb the impact force when the door 1 slides to its limit position. Further optimization can be achieved by adding a rubber buffer pad to the surface of the buffer door stops 24 to increase the buffering effect. A dustproof brush 3 is installed on the side of the door 1, fitting snugly against the gap between the door 1 and the cab. The bristles of the dustproof brush 3 completely cover this gap, forming a dynamic sealing barrier through the elastic bristles tightly adhering to the gap between the door and the cab. This effectively prevents outdoor dust and debris from entering the cab, ensuring a clean operating environment for equipment such as the electrical control cabinet and air conditioner, while also improving the air quality in the driver's workspace and reducing equipment maintenance frequency and labor costs. This application achieves linear movement of the door 1 through the sliding cooperation of the top slide rail 22 and the pulley 23, solving the problems of large space occupation and poor sealing of traditional hinged doors. It also features high space utilization, excellent dustproof effect, and smooth operation, making it suitable for space-constrained scenarios such as airport logistics.

[0025] To further enhance the operational stability of the sliding door, pulley 23 is installed on the top of the door body 1. Its outer circumference perfectly matches the groove of the slide rail 22, allowing it to slide tightly within the groove. High-precision bearings are installed inside pulley 23, making its rotation extremely flexible and effectively reducing the resistance when the door body 1 slides. To prevent pulley 23 from detaching from the slide rail 22 in extreme cases, anti-detachment flanges are provided on both sides of pulley 23. These flanges cooperate with the groove wall of the slide rail 22 to form a double anti-detachment protection structure, greatly improving the safety and reliability during the sliding process.

[0026] To further improve the operational stability of sliding doors, please refer to the appendix. Figure 2 and attached Figure 4 As shown, in this embodiment, a guide block 5 is fixed to the cab door frame by a first bolt 4. The guide block 5 cooperates with the side of the door body 1 to correct the sliding trajectory in real time, effectively preventing the door body 1 from shaking. The surface of the guide block 5 is polished and coated with a wear-resistant coating to reduce friction with the side of the door body. At the same time, multiple adjusting bolts are provided on the guide block 5, which can finely adjust the position of the guide block according to the actual installation situation to ensure the best fit with the side of the door body.

[0027] Preferred options are listed in the appendix. Figures 1-3 As shown, in this embodiment, the dustproof brush 3 is fixed to the door frame of the cab by the second bolt 6, the slide rail 22 and the bracket 21 are fixedly connected by the third bolt 7, the bracket 21 is fixed to the top of the cab by the fourth bolt 8, and the pulley 23 is fixed to the door 1 by the fifth bolt 9.

[0028] In terms of working principle, when the sliding door needs to be opened or closed, the operator applies external force to push or pull the door body 1 through the door handle 11. At this time, the pulley 23 installed on the top of the door body 1 will slide in the groove of the slide rail 22 along the set direction. Due to the precise cooperation between the pulley 23 and the slide rail 22, and the role of the high-precision bearing, the door body 1 can smoothly make linear reciprocating motion along the slide rail 22. During the sliding process of the door body 1, the guide block 5 cooperates with the side of the door body 1 to correct the sliding trajectory of the door body 1 in real time, prevent the door body 1 from shaking, and ensure the stability and accuracy of the sliding of the door body 1. When the door body 1 slides to the extreme positions of both ends of the slide rail 22, the buffer door stop 24 plays a role, using its own elasticity and buffering characteristics to absorb the impact force of the sliding of the door body 1, so that the door body 1 stops smoothly and avoids violent vibration and collision. At the same time, throughout the sliding process, the grease in the lubrication groove of the inner wall of the slide rail 22 continues to play a role, reducing the friction between the pulley 23 and the slide rail 22, ensuring smooth sliding and low-noise operation of the door body. This application achieves stable, smooth, and safe linear reciprocating motion of the sliding door through the precise structural design and coordinated operation of each component. It effectively solves the problems of large space occupation and poor sealing of traditional hinge doors, and provides an efficient and practical door solution for the driver's cab.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
