Description

Technical Field

[0001] This utility model belongs to the field of electric sliding doors, specifically, it relates to a new type of electric sliding door. Background Technology

[0002] Electric sliding doors are automated door systems widely used in commercial buildings, industrial plants, hospitals, and other places. They are driven by motors to achieve automatic opening and closing of the door, and have advantages such as convenient operation and space saving.

[0003] Currently, most electric sliding doors on the market rely on electric power. In the event of a power outage or motor failure, a backup power source or manual unlocking device is usually required to open the door, making operation cumbersome. While some products offer an emergency manual mode, the switching process is complex, and the lack of adequate clearance between the doors affects efficiency in emergencies. Furthermore, traditional sliding doors experience significant impact when closing, which can lead to frame deformation and track wear over time, affecting their lifespan. Although some products use cushioning strips or hydraulic shock absorbers to mitigate impact, these structures are often fixed, making replacement difficult and maintenance costs high.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a new type of electric sliding door, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A novel electric sliding door includes: a frame, a drive mechanism inside the frame, two sliding doors that cooperate with the drive mechanism and are slidably connected below the frame, door panels inside the sliding doors, the door panels having a hollow structure and the interior of the hollow structure being filled with flame retardant, several through holes communicating with the hollow structure being opened at the top of the door, a shock-absorbing strip being provided on one side of the sliding door, a positioning mechanism being fixedly connected to one side of the shock-absorbing strip, and the positioning mechanism passing through the door frame and cooperating with the drive mechanism.

[0008] Optionally, the drive mechanism includes a motor fixedly connected to one side of the frame, with a first synchronous pulley at the output end of the motor via bolts, a second synchronous pulley rotatably connected to one side of the frame, a synchronous belt sleeved between the first and second synchronous pulleys, the synchronous belt forming a rounded rectangular structure, and connectors for connecting between sliding doors fixedly connected above and below the synchronous belt.

[0009] Optionally, the connector includes a belt buckle that connects to the timing belt, a connecting plate that is fixedly connected to the lower side of one side of the belt buckle, an angle iron that is fixedly connected to one side of the connecting plate, a dovetail block that is fixedly connected to the lower side of the angle iron, and a dovetail groove that allows the dovetail block to slide is provided above the sliding door.

[0010] Optionally, the positioning mechanism includes a side plate fixedly connected to one side of the shock absorber strip, the side plate being attached to the inner side of the sliding door, and a threaded hole being provided on the opposite side of the side plate, with a bolt being threaded into the threaded hole, and a threaded groove matching the bolt being provided on one side of the sliding door.

[0011] Optionally, a connecting rod is fixedly connected to one side of the upper end of the shock-absorbing strip, a guide rod is fixedly connected to one side of the connecting rod, a through hole for the guide rod to slide is provided on one side of the dovetail groove, and an insertion interface corresponding to the through hole is provided on one side of the dovetail block.

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Please see Figure 1-5 As shown, this embodiment provides a novel electric sliding door, including a frame 1. A drive mechanism 2 is provided inside the frame 1. Two sliding doors 3 that cooperate with the drive mechanism 2 are slidably connected below the frame 1. A door panel 4 is provided inside the sliding door 3. The door panel 4 has a hollow structure and is filled with flame retardant. Several through holes 5 are provided above the door body and communicate with the hollow structure. A shock-absorbing strip 6 is provided on one side of the sliding door 3. A positioning mechanism is fixedly connected to one side of the shock-absorbing strip 6 and passes through the door frame and cooperates with the drive mechanism 2.

[0028] The positioning mechanism of this invention works in conjunction with the drive mechanism 2 to quickly switch to manual mode in the event of a power outage. After removing the shock-absorbing strip 6, an operating gap is created between the two sliding doors, facilitating emergency use. In automatic mode, the shock-absorbing strip 6 effectively absorbs the impact force when the doors close, resulting in smoother operation. This design ensures operability in emergency situations while reducing mechanical wear during daily use, thereby extending the service life of the sliding door 3.

[0029] In this embodiment, the drive mechanism 2 includes a motor 7 fixedly connected to one side of the frame 1. A first synchronous pulley 8 is fixedly connected to the output end of the motor 7. A second synchronous pulley 9 is rotatably connected to one side of the frame 1. A synchronous belt 10 is sleeved between the first synchronous pulley 8 and the second synchronous pulley 9. The synchronous belt 10 forms a rounded rectangular structure, and connectors for connecting the sliding doors 3 are fixedly connected above and below the synchronous belt 10. By connecting the belt buckle 11 to the upper and lower synchronous belts 10, the two sliding doors 3 can be driven to move relative to each other simultaneously. The movement of the sliding doors 3 can be achieved by the motor 7 using either a servo motor 7 or a self-locking motor 7, preferably a self-locking motor 7. The self-locking motor 7 improves stability when not in use. The flame retardant includes, but is not limited to, aluminum hydroxide. Aluminum hydroxide decomposes into aluminum oxide and water vapor at high temperatures. Furthermore, when the flame retardant decomposes under heat to produce volatiles such as water vapor, the through-hole 5 provides a discharge channel to prevent excessive pressure or structural damage caused by water vapor accumulation.

[0030] In this embodiment, the connector includes a belt buckle 11 connected to the synchronous belt 10. A connecting plate 12 is fixedly connected to the lower side of one side of the belt buckle 11. An angle iron 14 is fixedly connected to one side of the connecting plate 12. A dovetail block 15 is fixedly connected to the lower side of the angle iron 14. A dovetail groove 16 is provided above the sliding door 3 for the dovetail block 15 to slide. The dovetail block 15 and the dovetail groove 16 serve a guiding function, allowing the sliding door 3 to move by sliding the dovetail block 15 into the dovetail groove 16 when there is a problem with the power supply system. A roller 13 is rotatably connected to one side of the connecting plate 12. The roller 13 slides above the frame 1, facilitating the subsequent sliding of the connecting plate 12.

[0031] In this embodiment, the positioning mechanism includes a side plate 17 fixedly connected to one side of the shock-absorbing strip 6. The side plate 17 fits against the inner side of the sliding door 3, and a threaded hole 18 is provided on the opposite side of the side plate 17. A bolt is threaded into the threaded hole 18, and a threaded groove matching the bolt is provided on one side of the sliding door 3. The shock-absorbing strip 6 of the electric sliding door 3 of this utility model adopts a quick-release bolt fixing structure. By optimizing the bolt thread design, it can be locked or disassembled by rotating only half a turn (180°), which greatly improves the efficiency of disassembly and assembly. The bolt end integrates an ergonomic crank 23, which can still be quickly operated in case of vibration or structural deformation caused by an emergency such as a fire, ensuring that the shock-absorbing strip 6 can be replaced or maintained in the shortest possible time. At the same time, this design avoids the problem of traditional multi-turn threaded structures easily getting stuck in high-temperature environments.

[0032] In this embodiment, a connecting rod 20 is fixedly connected to one side of the upper end of the shock-absorbing strip 6, and a guide rod 21 is fixedly connected to one side of the connecting rod 20. A through hole 5 for sliding of the guide rod 21 is provided on one side of the dovetail groove 16, and an insertion interface 22 corresponding to the through hole 5 is provided on one side of the dovetail block 15. Through the cooperation between the dovetail block 15 and the dovetail groove 16, when a power system failure occurs, such as a power outage, damage to the motor 7, or an abnormal control signal, this mechanical emergency mechanism allows the user to quickly disconnect the door from the drive system: the guide rod 21 is inserted into the insertion interface 22 of the dovetail block 15, forming a rigid connection, allowing the door to move with the synchronous belt 10. Bolt linkage design: The bolt and the guide rod 21 adopt a linkage structure; rotating the bolt only requires half a turn to pull the guide rod 21 out of the insertion interface 22, releasing the mechanical coupling between the door and the drive mechanism 2. After disconnection, the door is only guided and constrained by the dovetail groove 16, and can be manually pushed and pulled along the track to ensure passage needs in emergency situations.

[0033] In this embodiment, one end of the bolt is fixedly connected to a crank handle 23 for easy rotation by a person. The crank handle 23 facilitates the rotation of the bolt.

[0034] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
