Description

Technical Field

[0001] This invention relates to the technical field of rail transit, specifically to an electric retraction door mechanism. Background Technology

[0002] Full-width automated driving trains, lacking a human driver's cab, typically have doors and emergency evacuation mechanisms at the front and rear. This allows for rapid evacuation of passengers in emergencies by opening the doors upwards and activating the emergency evacuation mechanisms at the front or rear. For example, patent CN111454698A discloses an escape device for a subway car. The door frame is fixedly installed in the subway car's doorway. A door lock device securely connects the lower part of the escape door to the door frame. The upper part of the escape door has a transparent window, and a top hinged linkage device is fixedly installed on the subway car's doorway. The upper part of the escape door is rotatably connected to the subway car's doorway via the top hinged linkage device. An unlocking device controls the door lock device, allowing the escape door to detach from the door frame and open upwards. Gas springs are installed on both sides of the escape door, with one end of each gas spring hinged to the escape door. The other end of the gas spring is hinged to the corresponding part of the mounting door frame. The gas spring is used to keep the escape door in the flip-open state. The escape ramp assembly includes a pedal frame assembly and a pedal. The pedal frame assembly is hinged to the lower part of the mounting door frame, and the pedal is set on the pedal frame assembly. When the pedal frame assembly is unfolded, it forms an escape ramp. During evacuation, the unlocking device unlocks, and the escape door flips upward under the action of the top hinge linkage device, thereby opening the evacuation passage. At the same time, the escape ramp assembly unfolds, laying a ramp for passengers to walk on in the evacuation passage, so that passengers can evacuate safely.

[0003] However, in existing full-width trains, after an emergency, the doors have already been opened upwards, requiring subsequent retraction and reset. Currently, the traditional method for resetting the opened doors involves connecting a cable to the bottom of the door. During retraction, the operator pulls down the cable to close the door. This process is entirely manual, requiring the operator to manually overcome the force of the gas spring, resulting in high labor intensity and inconvenience. Summary of the Invention

[0004] To address the aforementioned problems in existing technologies, this invention aims to provide an electrically retractable door mechanism. A sliding component is vertically installed within the side wall of the door frame, sliding within a track comprising two main channels and two transition channels connecting the main channels. Each main channel is equipped with an electric linear module, and one transition channel has an electric push rod. The two electric linear modules drive the sliding component to move within the corresponding main channel, thereby lowering the position of the gas spring hinged to the side wall of the door frame without compressing the gas spring. This allows the door to flip downwards under gravity, achieving electric retraction. After retraction, another electric push rod and the corresponding gas spring in the other main channel are hinged to the side wall of the door frame, compressing and resetting the gas spring. This meets the need for upward-flipping door mechanisms in emergency situations, eliminating the need for manual operation, reducing workload, and eliminating the need for cables, preventing cable interference with passenger evacuation and improving safety.

[0005] The specific technical solution is as follows:

[0006] An electric recycling gate mechanism is disposed between a gate frame and a gate leaf. The gate frame is located at the front end of the vehicle's front or rear. The top of the gate leaf is hinged to a crossbeam of the vehicle body. Gas springs are installed between both sides of the gate leaf and the side walls of the gate frame. The mechanism is characterized by the following features:

[0007] A sliding assembly is slidably mounted on the side wall of the door frame, and one end of the gas spring is hinged to the sliding assembly. The sliding assembly also has a protruding mating rod.

[0008] The slide plate is fixedly installed on the side wall of the door frame. The slide track is set on the slide plate. The slide track includes two main channels and two transition channels. The two main channels are arranged at intervals in the vertical direction. The two transition channels are respectively set at the upper and lower ends of the two main channels and connect the upper and lower ends of the two main channels. The sliding component is slidably installed in the slide track, and the matching rod extends out of the slide track.

[0009] Electric linear modules are installed on the slide plate. Each main channel has a parallel electric linear module, and each electric linear module is equipped with a mating block that is selectively connected to the mating rod.

[0010] An electric linear actuator is mounted on a slide plate and arranged parallel to the transition channel at the lower end of the main channel. The electric linear actuator is equipped with a push block that selectively contacts the mating rod.

[0011] In the aforementioned electric recycling door mechanism, the sliding component further includes a slider with a circular cross-section. The slider is slidably disposed within a slide rail, and a coaxial rod is coaxially disposed at the center of the slider.

[0012] In the aforementioned electric recycling door mechanism, the two main channels are a recycling channel and a compression channel. The recycling channel is located on the side of the compression channel away from the door, and the upper end of the compression channel is higher than the upper end of the recycling channel. Furthermore, the two transition channels located at the upper and lower ends of the main channels are an exit channel and a feed channel, respectively. One end of the exit channel is connected to the compression channel and is located below the top of the compression channel, forming a limiting cavity at the top of the compression channel.

[0013] In the aforementioned electric recycling door mechanism, the height of the end of the exit channel connected to the compression channel is higher than the height of the end of the exit channel connected to the recycling channel.

[0014] In the aforementioned electric recycling door mechanism, the corners where the exit channel and the recycling channel connect, as well as the corners where the feed channel connects to the recycling channel and the compression channel respectively, are all smoothly rounded.

[0015] In the aforementioned electric recycling door mechanism, an electric push rod is disposed on the side of the recycling channel away from the compression channel, and the push shaft of the electric push rod is arranged toward the side of the compression channel and performs reciprocating motion toward or away from the compression channel.

[0016] In the aforementioned electric recycling door mechanism, the mating block includes a movable plate, a fixed baffle, a rotating arm, a movable baffle, and a rotary driver. The movable plate is mounted on the sliding component of the electric linear module. One side of the movable plate extends to the slide rail and is suspended beside the slide rail. A fixed baffle and a rotating arm are provided on the side of the movable plate near the slide rail. The fixed baffle is located at the lower part of the movable plate and extends towards the slide rail. Meanwhile, one end of the rotating arm is rotatably mounted on the movable plate, and the other end of the rotating arm is fixedly mounted with a movable baffle extending towards the slide rail. The rotary driver is mounted on the movable plate and located on the side of the movable plate away from the slide rail. Furthermore, the drive shaft of the rotary driver is rotatably connected to one end of the rotating arm that is powered on the movable plate.

[0017] In the aforementioned electric recycling door mechanism, the upper part of the push block near the compression channel is provided with a receiving notch, and the depth of the receiving notch is greater than the thickness of the movable baffle. At the same time, when the sliding component is located in the transition channel at the lower end of the main channel, the lower edge of the receiving notch is at the same height as the central axis of the mating rod.

[0018] In the aforementioned electric recycling door mechanism, when the mating block of the electric linear module corresponding to the compression channel moves to its highest point, the sliding component is located in the limiting cavity, and the mating block seals the lower outlet of the limiting cavity.

[0019] The positive effects of the above technical solution are:

[0020] The aforementioned electric recycling door mechanism features a sliding plate on the side wall of the door frame, with a slide rail consisting of two vertically arranged main channels and a transition channel connecting the upper and lower ends of the two main channels. The end of a gas spring hinged to the door leaf is hinged to a sliding assembly and slides within the slide rail. The sliding assembly has a mating rod extending beyond the slide rail. Each main channel corresponds to a parallel-arranged electric linear module, and the transition channel connected to the lower end of the main channel is equipped with a parallel-arranged electric push rod. Each electric linear module has a mating block selectively connected to the mating rod, and the electric push rod has a mating block that connects to the mating rod. The push block, selectively connected to the linkage rod, can drive one end of the gas spring hinged to the side wall of the door frame to move downward along a main channel. This allows the door to flip down and retract when the gas spring is deployed. After retraction, the push block transfers the sliding assembly from one main channel to another, and another linkage block moves the end of the lifting spring hinged to the side wall of the door frame to its highest point, compressing the gas spring and maintaining its normal operation. The entire process requires no manual operation, reducing workload and eliminating the need for cable installation, thus preventing cable interference with passenger evacuation and improving evacuation safety.

[0028] To make the technical means, creative features, objectives, and effects of this invention easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 6 The technical solutions provided by this invention are described in detail, but the following content is not intended to limit this invention.

[0029] Figure 1 This is a structural diagram of an embodiment of an electric recycling door mechanism according to the present invention; Figure 2 This is a schematic diagram illustrating the interaction of the skateboard, sliding assembly, electric linear module, and electric push rod according to a preferred embodiment of the present invention. Figure 1 and Figure 2 As shown, the electric retraction door mechanism provided in this embodiment is located between the door frame 1 and the door leaf 2. The door frame 1 is positioned at the very front of the vehicle's front and rear, and the top of the door leaf 2 is hinged to the vehicle's crossbeam. This allows the door leaf 2 to be opened upwards in an emergency and to be retracted downwards. Furthermore, gas springs 3 are installed between both sides of the door leaf 2 and the side walls of the door frame 1. When the door leaf 2 is opened to a predetermined angle, it automatically flips upwards under the action of the gas springs 3 and is stably supported by them, maintaining the unobstructed evacuation passage.

[0030] In addition, the electric retraction door panel 2 mechanism provided in this embodiment includes a sliding component 4, a sliding plate 5, an electric linear module 6, and an electric push rod 7. In this case, the sliding plate 5 is set on the side wall of the door frame 1, the sliding component 4 is slidably mounted on the sliding plate 5, and one end of the gas spring 3 is hinged to the sliding component 4 on the side wall of the door frame 1. That is, by changing the position of the gas spring 3 hinged to the side wall of the door frame 1, it is possible to achieve the downward flipping of the door panel 2 without retracting the gas spring 3, and also to compress the gas spring 3 in the reverse direction after the door panel 2 is closed, thus preserving the function of the gas spring 3 for normal use. No manual intervention is required throughout the process, realizing the electric retraction of the door panel 2, reducing the workload, and eliminating the need for cable installation, thus avoiding the problem of cable interference with evacuation and improving the safety of evacuation.

[0031] Specifically, the sliding assembly 4 is slidably mounted on the side wall of the door frame 1, allowing it to move along the side wall. One end of the gas spring 3, hinged to the side wall of the door frame 1, is also hinged to the sliding assembly 4. This allows the position of the gas spring 3 hinged to the side wall of the door frame 1 to change as the sliding assembly 4 moves. For example, when the sliding assembly 4 moves downwards, the position of the gas spring 3 hinged to the side wall of the door frame 1 moves downwards, allowing the door leaf 2 to be retracted without the gas spring 3 retracting. Conversely, after the door leaf 2 is locked, the sliding assembly 4 moves upwards, allowing the position of the gas spring 3 hinged to the side wall of the door frame 1 to move upwards, compressing the gas spring 3 while the door leaf 2 remains stationary. This ensures that the gas spring 3 can meet the normal usage requirements during subsequent emergency situations. Furthermore, the sliding assembly 4 has a protruding mating rod 41, providing a condition for the subsequent selective engagement of the sliding assembly 4 with the electric linear module 6 and the electric push rod 7 via the mating rod 41.

[0032] Specifically, the slide plate 5 is fixedly installed on the side wall of the door frame 1. A slide rail is then placed on the slide plate 5, and the slide rail includes two main channels 51 and two transition channels 52, providing guidance for the subsequent sliding of the sliding component 4 on the slide plate 5. Furthermore, the two main channels 51 are arranged vertically at intervals, providing conditions for one main channel 51 to serve as the slide rail for the downward movement of the sliding component 4, and the other main channel 51 to serve as the slide rail for the upward movement of the sliding component 4. The two transition channels 52 are respectively located at the upper and lower ends of the two main channels 51, connecting the upper and lower ends of the two main channels 51, thus forming a ring structure in the slide rail, providing conditions for the cyclical movement of the subsequent sliding component 4. In addition, the sliding component 4 is slidably placed within the slide rail, allowing the movement of the sliding component 4 to be guided by the slide rail, improving the stability of the movement of the sliding component 4. Furthermore, extending the mating rod 41 outside the slide provides conditions for the subsequent selective connection of the mating rod 41 with the electric linear module 6 and the electric push rod 7.

[0033] Specifically, the electric linear module 6 is installed on the slide plate 5. At this time, each main channel 51 corresponds to a parallel-arranged electric linear module 6, so that the sliding component 4 is driven by the corresponding electric linear module 6 during its sliding within both main channels 51, providing buffering or pushing force for the movement of the sliding component 4. In addition, each electric linear module 6 is provided with a mating block 61 that selectively connects to the mating rod 41. That is, when the electric linear module 6 selectively engages with the sliding component 4, it is achieved through the selective engagement of the mating block 61 with the mating rod 41.

[0034] Specifically, the electric push rod 7 is mounted on the slide plate 5. The electric push rod 7 is arranged parallel to the transition channel 52 at the lower end of the main channel 51, ensuring that the pushing direction of the electric push rod 7 is consistent with the arrangement direction of the transition channel 52. This provides power for the electric push rod 7 to subsequently push the sliding assembly 4 within the transition channel 52 from one main channel 51 to another. Furthermore, a push block 71 is provided on the electric push rod 7, selectively contacting the mating rod 41. This allows the electric push rod 7 to selectively engage with the sliding assembly 4 through the selective engagement of the push block 71 and the mating rod 41.

[0035] More specifically, the sliding assembly 4 also includes a slider 42, whose cross-section is arranged in a circular shape, making the outer wall of the slider 42 smoother and facilitating its subsequent transfer within different channels of the slide rail. Furthermore, the slider 42 is slidably positioned within the slide rail, allowing it to slide along the rail and meet the position adjustment requirements of the sliding assembly 4. Additionally, the mating rod 41 is coaxially positioned at the center of the slider 42, ensuring that when the mating rod 41 subsequently engages with the mating block 61 and the push block 71, the force exerted on the mating rod 41 is concentrated at the center of the slider 42, guaranteeing uniform force distribution on the slider 42 and ensuring smooth sliding within the slide rail. This results in a more rational structural design.

[0036] More specifically, the two main channels 51 of the slide are a retraction channel 511 and a compression channel 512. The retraction channel 511 guides the sliding component 4 when the door leaf 2 is retracted, while the compression channel 512 guides the sliding component 4 when the gas spring 3 is compressed after the door leaf 2 is retracted. This not only enables the door leaf 2 to be retracted but also provides conditions for the normal opening of the door leaf 2. In addition, the retraction channel 511 is located on the side of the compression channel 512 away from the door leaf 2, that is, the distance between the retraction channel 511 and the door leaf 2 is greater than the distance between the compression channel 512 and the door leaf 2. This allows for more space for the movement of the gas spring 3 when the door leaf 2 is retracted and the gas spring 3 has not retracted. The sliding component 4, which needs to be moved downward, also moves slightly in the horizontal direction. This allows the vertical movement to be converted into horizontal movement without changing the length of the gas spring 3, thus avoiding the need for sufficient depth to accommodate the movement of the gas spring 3, which is more suitable for applications with limited vehicle height space.

[0037] In addition, the upper end of the compression channel 512 is higher than the upper end of the recovery channel 511, so that the upper end of the compression channel 512 has more space than the upper end of the recovery channel 511, which provides a temporary fixed position for the sliding assembly 4 when compressing the gas spring 3 later. Furthermore, two transition channels 52 located at the upper and lower ends of the main channel 51 are respectively the exit channel 521 and the feed channel 522, allowing the two main channels 51 to be connected through the exit channel 521 and the feed channel 522. The end of the exit channel 521 connected to the compression channel 512 is located below the top of the compression channel 512 and forms a limiting cavity 513 at the top of the compression channel 512. This ensures that the space below the part of the exit channel 521 that connects to the compression channel 512 is below the compression channel 512, and also makes the exit channel 521 inclined. In use, after the door leaf 2 is opened upwards, the sliding component 4 is pushed into the limiting cavity 513 by the mating block 61 and confined within the limiting cavity 513, thus restricting the sliding component 4 on all sides, allowing the gas spring 3 to stably support the door leaf 2. When the door leaf 2 needs to be retracted, the mating block 61 is first controlled to move downwards a certain distance so that the upper edge of the mating block 61 is aligned with the exit channel 521. The lower edge is flush with the gas spring 513, thus connecting the limiting cavity 513 with the exit channel 521. Under the action of gravity, the sliding component 4 moves down from the limiting cavity 513 to the exit channel 521 and moves along the exit channel 521 to the retraction channel 511, so that the sliding component 4 moves down along the retraction channel 511, thereby realizing the retraction of the door leaf 2 without the gas spring 3 retracting, satisfying the retraction requirement of the door leaf 2. After the door leaf 2 is retracted, the door leaf 2 is locked first. At this time, the electric push rod 7 pushes the sliding component 4 through the push block 71, so that the sliding component 4 enters the feed channel 522 from the retraction channel 511, and then moves to the compression channel 512 under the guidance of the feed channel 522. The sliding component 4 is then pushed by the corresponding mating block 61 of the compression channel 512 to move back to the limiting cavity 513, thereby compressing the gas spring 3, thus adapting to the use requirement that the door leaf 2 can be opened by the gas spring 3 in an emergency. It is worth noting that after the sliding component 4 enters the exit channel 521, the mating block 61 of the electric linear module 6 corresponding to the compression channel 512 moves down to the bottom of the compression channel 512, which provides the conditions for the subsequent sliding component 4 to enter the compression channel 512 from the feed channel 522 and be pushed up again by the mating block 61 of the electric linear module 6 corresponding to the compression channel 512.

[0038] More specifically, the height of the end of the exit channel 521 connected to the compression channel 512 is higher than the height of the end of the exit channel 521 connected to the recycling channel 511, so that the exit channel 521 is arranged at an angle, and the height of the exit channel 521 decreases as it moves further away from the door leaf 2. This allows the sliding component 4 to move from the limiting cavity 513 to the exit channel 521 and to slide within the exit channel 521, all of which can be powered by the weight of the door leaf 2 itself. No additional drive structure is required, resulting in a simple structure and saving manufacturing and usage costs.

[0039] More specifically, the corners connecting the exit channel 521 and the recovery channel 511, the feed channel 522 and the recovery channel 511, and the feed channel 522 and the compression channel 512 are all smoothly transitioned, so that the sliding component 4 can move more smoothly between the exit channel 521 and the recovery channel 511, between the recovery channel 511 and the feed channel 522, and between the feed channel 522 and the compression channel 512, thus avoiding jamming problems.

[0040] More specifically, the electric push rod 7 is positioned on the side of the recovery channel 511 away from the compression channel 512. At the same time, the push shaft of the electric push rod 7 is arranged facing the side of the compression channel 512, so that the push shaft of the electric push rod 7 can reciprocate towards or away from the compression channel 512. That is, when the sliding component 4 moves down to the bottom of the recovery channel 511, the push block 71 of the electric push rod 7 can push the sliding component 4 from the bottom of the recovery channel 511 into the feed channel 522 and into the bottom of the compression channel 512 along the feed channel 522, thus providing conditions for the subsequent compression of the gas spring 3.

[0041] Figure 3 This is a schematic diagram of a preferred embodiment of the present invention when the mating block corresponding to the compression channel is at its highest point. Figure 4 This is a schematic diagram of a preferred embodiment of the present invention when the mating block corresponding to the compression channel is at its lowest point and is engaged with the electric push rod. Figure 5 This is a schematic diagram of a preferred embodiment of the present invention when the mating block corresponding to the recycling channel is at its highest point; Figure 6 This is a schematic diagram of a preferred embodiment of the present invention when the mating block corresponding to the recycling channel is at its lowest point. Figures 2 to 6As shown, each mating block 61 of the electric linear module 6 includes a movable plate 611, a fixed baffle 612, a rotating arm 613, a movable baffle 614, and a rotary driver 615. The movable plate 611 is mounted on the sliding member of the electric linear module 6, allowing it to move with the electric linear module 6 under the influence of the sliding member. Simultaneously, one side of the movable plate 611 extends to the slide rail and is suspended beside it, preventing collisions with the mating rod 41 during subsequent movement and providing conditions for the movable plate 611 to drive the mating rod 41 to move. In addition, a fixed baffle 612 and a rotating arm 613 are provided on the side of the movable plate 611 near the slide rail. At this time, the fixed baffle 612 is set at the lower part of the movable plate 611 and extends towards the slide rail side, so that when the mating rod 41 of the subsequent sliding component moves to the movable plate 611, the lower part of the mating rod 41 can be restricted by the fixed baffle 612, which provides support for the subsequent upward movement of the sliding component 4 through the fixed baffle 612 and prevents the sliding component 4 from moving downward too quickly. Meanwhile, one end of the rotating arm 613 is rotatably mounted on the movable plate 611, allowing the rotating arm 613 to deflect within the plane of the movable plate 611. A movable baffle 614 extending towards the slide rail is fixedly mounted on the other end of the rotating arm 613, enabling the rotating arm 613 to move the movable baffle 614 on the movable plate 611, changing its position. This allows the movable baffle 614 to deflect either above or above the fixed baffle 612, thus limiting the movement of the mating rod 41. Furthermore, the rotary actuator 615 is mounted on the movable plate 611 and located on the side of the movable plate 611 away from the slide rail, fulfilling the requirement for the rotary actuator 615 to move synchronously with the movable plate 611. Furthermore, the drive shaft of the rotary driver 615 is rotatably connected to one end of the rotary arm 613 on the movable plate 611, so that the rotary driver 615 can drive the rotary arm 613 to rotate on the movable plate 611, thereby providing driving force for the position adjustment of the movable baffle 614 on the movable plate 611.It is worth noting that when the sliding assembly 4 enters the limiting cavity 513 from the compression channel 512, the movable baffle 614 is located above and to the side of the fixed baffle 612. The movable baffle 614 limits the side of the mating rod 41, preventing the sliding assembly 4 from accidentally entering the exit channel 521 when it enters the limiting cavity 513 from the compression channel 512. This ensures that the sliding assembly 4 can smoothly enter the limiting cavity 513. When the door leaf 2 needs to be retracted, the moving plate 611 moves down, making the fixed baffle 612 flush with the lower edge of the exit channel 521, and rotating the movable baffle 614 to a position directly above the fixed baffle 612. This releases the restriction on the side of the mating rod 41, allowing the mating rod 41 to enter the exit channel 521 between the movable baffle 614 and the fixed baffle 612. In addition, after the mating rod 41 enters the exit channel 521, the movable baffle 614 on the mating block 61 of the electric linear module 6 corresponding to the recycling channel 511 is located directly above the fixed baffle 612. This allows the mating rod 41 in the exit channel 521 to move between the movable baffle 614 and the fixed baffle 612. Then, the fixed baffle 612 and the movable baffle 614 together restrict the movement of the mating rod 41 in the vertical direction, thereby controlling the sliding component 4 to move slowly in the recycling channel 511, controlling the recycling speed of the door leaf 2, avoiding the problem of rapid impact during the recycling process of the door leaf 2, and improving safety protection. Additionally, when the sliding assembly 4 moves to the bottom of the recovery channel 511, the push block 71 of the electric push rod 7 extends from between the movable baffle 614 and the fixed baffle 612, which are arranged vertically, and contacts the mating rod 41, pushing the sliding assembly 4 into the feed channel 522 and moving it along the feed channel 522 toward the compression channel 512. At this time, the movable baffle 614 on the mating block 61 of the electric linear module 6 corresponding to the compression channel 512 is initially positioned directly above the fixed baffle 612, thereby allowing the push block 71 to... The mating rod 41 is pushed between the movable baffle 614 and the fixed baffle 612, and then the movable baffle 614 is rotated to a position above the fixed baffle 612. This limits the side of the mating rod 41, thus preventing the mating rod 41 from accidentally retracting into the feed channel 522 after the electric push rod 7 is withdrawn. This ensures that the sliding assembly 4 can move smoothly upward along the compression channel 512 to compress the gas spring 3 and push the sliding assembly 4 into the limiting cavity 513, meeting the door leaf 2 opening requirements in subsequent emergency situations.

[0042] More specifically, a receiving notch 711 is provided on the upper part of the push block 71 near the compression channel 512, and the depth of the receiving notch 711 is greater than the thickness of the movable baffle 614. This prevents the movable baffle 614 from being blocked by the push block 71 when it is subsequently moved into the receiving notch 711. Simultaneously, when the sliding assembly 4 is located in the transition channel 52 at the lower end of the main channel 51, the lower edge of the receiving notch 711 is set to be at the same height as the central axis of the mating rod 41. This allows the lower part of the mating rod 41 to contact the push block 71 when the push block 71 pushes the mating rod 41, enabling the push block 71 to push the sliding assembly 4 from the feed channel 522 into the compression channel 512. After the sliding assembly 4 moves into the compression channel 512, it is necessary to control the movable baffle 614 to rotate to the side of the fixed baffle 612. At the upper position, the movable baffle 614 blocks the side of the mating rod 41. The movable baffle 614 can be rotated by a predetermined angle to move into the receiving notch 711. The upper part of the mating rod 41 is limited by the movable baffle 614. Then the push block 71 is reset. During the reset process of the push block 71, the mating rod 41 can be prevented from accidentally retracting. After the push block 71 moves away from the mating rod 41, the movable baffle 614 continues to rotate, which ensures that the mating rod 41 can be stably limited. The structural design is more reasonable.

[0043] More specifically, when the mating block 61 of the electric linear module 6 corresponding to the compression channel 512 moves to the highest point, the sliding component 4 is located in the limiting cavity 513. The mating block 61 seals the lower outlet of the limiting cavity 513, that is, the height of the fixed baffle 612 on the mating block 61 will not be lower than the upper edge of the exit channel 521, so that the mating rod 41 can be stably placed in the limiting cavity 513, thereby avoiding the problem of the gas spring 3 failing due to the sliding component 4 accidentally moving down during normal vehicle operation. The structural design is more reasonable.

[0044] The electric retraction door mechanism provided in this embodiment includes a sliding assembly 4, a sliding plate 5, an electric linear module 6, and an electric push rod 7. A sliding plate 5, comprising two main channels 51 and a transition channel 52 connecting the upper and lower ends of the two main channels 51, is provided on the side wall of the door frame 1. The end of a gas spring 3, hinged to the door leaf 2, is hinged to the sliding assembly 4, which is slidably disposed within the track. Simultaneously, each main channel 51 corresponds to an electric linear module 6 selectively connected to the sliding assembly 4. The electric push rod 7 is disposed at the transition channel 52 at the lower end of the main channel 51 and selectively connected to the sliding assembly 4, enabling the door to retract... When retracting door leaf 2, an electric linear module 6 can drive the sliding component 4 to move downward, so that door leaf 2 can be retracted without the gas spring 3 retracting, thus meeting the electric retraction requirement of door leaf 2. After door leaf 2 is retracted, the sliding component 4 can be transferred to another main channel 51 by an electric push rod 7, and the sliding component 4 can be pushed upward by another electric linear module 6 to compress the gas spring 3, maintaining the normal function of the gas spring 3 and meeting the subsequent opening and support requirements of door leaf 2. The whole process does not require manual intervention, saving time and effort in retraction, and there is no need to install pull cables, which improves evacuation safety.

[0045] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
