The first embodiment is as follows:

fig. 1-4 are schematic structural views of the swing arm sliding door mechanism of the embodiment. As shown in fig. 1-4, the swing arm sliding door mechanism comprises a mounting frame 1, a sliding door 2, a first transmission assembly 3, a second transmission assembly 4 and a driving device 5. Wherein, the mounting bracket 1 is provided with a first track 11, and the sliding door 2 is provided with a second track 21. One end of the first transmission component 3 is rotatably connected with the sliding door 2, and the other end is arranged on the first track 11 and can slide along the first track 11. One end of the second transmission assembly 4 is rotatably connected with the mounting frame 1, the other end of the second transmission assembly 4 is connected with the second track 21, and the other end of the second transmission assembly 4 can move along the second track 21. The driving device 5 is in transmission connection with the second transmission assembly 4. In this embodiment, the driving device 5 is controlled to drive the second transmission assembly 4 and the second track 21 to move relatively, and drive the first transmission assembly 3 to move along the first track 11, so that the sliding door 2 can stably move along a predetermined path, and the sliding door 2 can be opened or closed.

Specifically, the mounting frame 1 is parallel to the sliding door 2, and the sliding door 2 is controlled to move relative to the mounting frame 1 to open or close the sliding door 2. In this embodiment, the mounting bracket 1 includes a first bracket 12 and a second bracket 13, and the first bracket 12 is vertically connected to the second bracket 13. Wherein the first bracket 12 is parallel to the height direction of the sliding door 2, and the second bracket 13 is parallel to the width direction of the sliding door 2. Further, the second transmission assembly 4 is disposed inside the first bracket 12, and one end of the second transmission assembly 4 is rotatably connected to the first bracket 12. That is, the second transmission assembly 4 is always located inside the first frame 12 during the relative rotation with the first frame 12. When the sliding door 2 is opened relative to the mounting frame 1, the second bracket 13 extends to one side far away from the sliding door 2, and the first transmission assembly 3 is rotatably connected with the other side of the sliding door 2 close to the mounting frame 1, as shown in fig. 3. Further, the first bracket 12 is provided with a step, and the step structure is arranged on a side of the first bracket 2 facing the sliding door 2. When the sliding door 2 is controlled to be closed, the sliding door 2 can be positioned in the ladder of the first bracket 12 and is flush with the side edge of the first bracket 12, and the sealing performance and the aesthetic property when the sliding door 2 is closed can be improved. Preferably, the mounting bracket 1 may be made of rectangular steel. To avoid affecting the entry and exit of personnel, the second support 13 is arranged near the top of the first support 12.

In another alternative implementation, the mounting frame 1 comprises two first brackets 12, a second bracket 13 and a cross beam 14. The beam 14 is arranged on the top of two parallel first brackets 12, forms a door-shaped structure with the first brackets 12, and the second bracket 13 is vertically arranged between the two parallel first brackets 12. The distance between the second bracket 13 and the cross beam 14 can be set according to specific requirements so as to avoid the sliding door 2 from being opened and collision when parts pass through. The door-shaped structure can improve the sealing property and the aesthetic property when the sliding door 2 is closed.

Further, the first track 11 is disposed on the top of the second bracket 13, one end of the first transmission assembly 3 is rotatably connected to one side of the sliding door 2, and the other side of the first transmission assembly moves along the first track 11. The first rail 11 includes a third linear rail 111, a fourth linear rail 112 perpendicular to the third linear rail 111, and a second arc-shaped rail connecting the third linear rail 111 and the fourth linear rail 112. Alternatively stated, the second arcuate rail is configured to perpendicularly connect the fourth linear rail 112 at a first end of the third linear rail 111. That is, the first track 11 is a track of an approximately L-shaped structure. The third linear rail 111 is parallel to the sliding door 2, and the fourth linear rail 112 is perpendicular to the sliding door 2 and extends to a side away from the sliding door 112, as shown in fig. 3. Preferably, the third linear rail 111 and the fourth linear rail 112 are connected by an arc, so that the first transmission assembly 3 can achieve good movement on the first track 11. In this embodiment, the first end of the third linear rail 111 is a side far away from the second transmission assembly 4 connected to the mounting bracket 1, that is, the first end of the third linear rail 111 is a side far away from the first bracket 12. In this embodiment, the first rail 11 may be configured as a sliding rail, or may be configured as two parallel sliding grooves. The first transmission assembly 3 is provided as a corresponding structure movable along the first track 11.

Specifically, the position where the first transmission assembly 3 and the sliding door 2 are rotatably connected is adapted to the height of the second bracket 12, so that the first transmission assembly 3 can drive the sliding door 2 to perform parallel swinging along the first track 11 at a predetermined height. The first transmission assembly 3 comprises a second transmission arm 31 and a second transmission member 32. One end of the second transmission arm 31 is rotatably connected to the sliding door 2. In this embodiment, one end of the second transmission arm 31 has a connection hole. Correspondingly, the sliding door 2 is fixedly provided with a connecting block, and the connecting block is provided with a through hole. The connecting hole of the second driving arm 31 can be rotatably connected with the through hole of the sliding door 2 through a bolt, a pin rod and the like after being aligned. Specifically, the diameter of the bolt or pin is smaller than that of the hole, and the two ends of the bolt or pin are larger than that of the hole, so that the second transmission arm 31 is rotatably connected with the sliding door 2.

The second transmission member 32 is disposed at the other end of the second transmission arm 31 and is configured to move along the first track 11. In this embodiment, the first transmission assembly 3 is located above the second bracket 13, and the second transmission member 32 is located at the bottom of the second transmission arm 31 and is matched with the first rail 11 located at the top of the second bracket 13, so as to prevent the first transmission assembly 3 from being separated from the first rail 11 during the lateral movement.

In this embodiment, the first rail 11 may be a convex rail. The second transmission members 32 are divided into two groups, each group including at least one roller. In one embodiment, two sets of second transmission members 32 are respectively disposed on two sides of the first rail 11, and the two sets of second transmission members 32 are configured to move or rotate the second transmission arms 31 when moving along two sides of the first rail 11. In the process that the second transmission member 32 moves along the first rail 11, rolling friction occurs between the second transmission member 32 (roller) and the side surface of the first rail 11, so that friction on the second transmission member 32 can be reduced, and the service life of the second transmission member 32 can be prolonged. In another alternative implementation, the roller may also be fixedly connected to the second transmission arm 31, and during the movement, sliding friction occurs with the side of the first rail 11.

When the sliding door 2 is opened to be parallel to the third linear rail 111 of the first track 11, the first transmission assembly 3 and the second transmission assembly 4 are limited in rotation in the opening direction and can not rotate any more; one gear or roller is disposed adjacent to the inner side of the curved rail of the first rail 11 and/or the second rail 21, and two to three gears or rollers are disposed adjacent to the outer side of the first rail 11 and/or the curved rail. When the third linear rail 111 moves, a triangular structure is formed by one gear or roller inside the rail and 2 or more most edgemost gears or rollers outside the rail, thereby always maintaining the angle when the first and

second transmission arms

41 and 31 move. Namely, the sliding door 2 is guaranteed to always keep opening in parallel movement after the arc-shaped rail is opened.

Further, referring to fig. 2, the first driving assembly 3 further includes at least one second supporting member 34, and the second supporting member 34 is disposed below the second driving arm 31 and above the first rail 11, and contacts with an upper surface of the first rail 11, for supporting the second driving arm 31 and the sliding door 2 connected to the second driving arm 31. The second support member 34 may be connected with the second transmission arm 31. Alternatively, the second support member 34 may be in rolling contact with the upper surface of the first rail 11, enabling a reduction in friction. Referring to fig. 1 to 4, in one implementation, the second supporting members 34 are rollers, the rotating shafts of the second supporting members 34 are perpendicular to the rotating shafts of the second transmission members 32, and the second supporting members 34 are disposed between two sets of the second transmission members 32 respectively located at two sides of the first rail 11, so as to prevent the second supporting members 34 and the second transmission members 32 from affecting each other.

Fig. 5 is a schematic structural view of a second limiting member and a first rail of the present embodiment, which is different from those in fig. 1 to 4. Referring to fig. 5, in another alternative implementation, the first rail 11 has two substantially parallel runners (i.e., runner 11a and runner 11 b). Correspondingly, the second transmission component 32 includes 2 guide pulleys and one bearing roller, the pulley shaft and the roller shaft are arranged perpendicularly, the pulleys are arranged in the sliding groove 11a and the sliding groove 11b, the second transmission arm 31 can be driven to move along the two parallel sliding

grooves

11a and 11b, and the bearing roller rolls at the bottom of the sliding groove to bear the load of the second transmission component 32.

In the embodiment, since the third linear rail 111 is parallel to the sliding door 2, and the distance between the third linear rail 111 and the sliding door 2 is matched with the length of the second transmission arm 31, when the second transmission member 32 moves on the third linear rail 111 of the first rail 11, the second transmission arm 31 drives the sliding door 2 to translate. Because the fourth linear rail 112 is perpendicular to the third linear rail 111, that is, the fourth linear rail 112 is perpendicular to the sliding door 2, and the length of the second transmission arm 31 is fixed, when the second transmission member 32 moves from the third linear rail 111 of the first rail 11 to the fourth linear rail 112, the second transmission arm 31 and the sliding door 2 rotate relatively to drive the sliding door 2 to swing to the side where the mounting frame 1 is located, so as to close the sliding door 2. When the second transmission member 32 moves from the fourth linear rail 112 of the first rail 11 to the third linear rail 111, the second transmission arm 31 and the sliding door 2 rotate relatively to drive the sliding door 2 to swing to a side away from the mounting frame 1, so as to open the sliding door 2.

In another alternative implementation, the first track 11 may also be disposed at the bottom of the second bracket 13, and the first transmission assembly 3 is disposed below the second bracket 13. Correspondingly, the second transmission member 32 is disposed above the second transmission arm 31 and moves along the first track 11. In the present embodiment, the structures of the first rail 11 and the first transmission assembly 3 are the same as those of the above-described implementation, and only the difference is that the first rail 11 and the first transmission assembly 3 are symmetrically disposed below the second bracket 13, and a description thereof will not be repeated.

In some embodiments, the second rail 21 has substantially the same shape as the first rail, the second rail 21 remains fixed relative to the sliding door 2, and the first rail 11 remains fixed relative to the mounting bracket 1 (i.e., the first rail 21 remains fixed relative to the vehicle body). The second rail 21 is provided on the inner side of the sliding door 2, and is disposed substantially in parallel with the first rail 11. The second track 21 comprises a first linear track 211, a second linear track 212 perpendicular to said first linear track 211, and a first arcuate track connecting the first linear track and the second linear track. That is, the first arcuate rail is configured to vertically connect the second linear rail 212 at a first end of the first linear rail 211. The first linear rail 211 is parallel to the swing arm 2, and the second linear rail 212 extends to a side close to the sliding door 2 and is perpendicular to the sliding door 2. That is, the second track 21 is an approximately L-shaped track. The first end of the first linear rail 211 is a side far away from the first transmission component 3 connected with the sliding door 2 when the sliding door 2 is opened. In this embodiment, the second rail 21 is an L-shaped rack, and the rack structure is disposed on a side close to the mounting rack 1 and is in transverse meshing transmission connection with the second transmission assembly 4. In the present embodiment, the second rail 21 is located above the first rail 11, that is, the second transmission assembly 4 in transmission connection with the second rail 21 is located above the first transmission assembly 3.

Specifically, the position where the second transmission assembly 4 and the first bracket 12 are rotatably connected is adapted to the height of the second track 21, so that the second transmission assembly 4 can drive the sliding door 2 to swing along the second track 11. The second transmission assembly 4 comprises a first transmission arm 41 and a first transmission member 42. One end of the first transmission arm 41 is rotatably connected to the first bracket 12 in the same manner as the second transmission arm 31 is rotatably connected to the swing door 2, and a description thereof will not be repeated.

In this embodiment, the first transmission arm 41 is disposed below the second rail 21, and the first transmission member 42 is disposed on one side above the first transmission arm 41, is in transverse transmission connection with the second rail 21, and is configured to be controlled to rotate and move relative to the second rail 21 to drive the sliding door 2 to move along a predetermined path, so as to open or close the sliding door 2. In this embodiment, the first transmission member 42 includes at least one gear in meshing engagement with the rack gear. When the gear is controlled to rotate, the rack and the gear move relatively to realize meshing transmission. Because the rack is fixedly arranged on the sliding door 2, when the rack and the gear move relatively, the sliding door 2 and the gear move relatively, and the sliding door 2 is opened or closed.

In the present embodiment, the first transmission member 42 is connected to the driving device 5, and the driving device 5 drives the gear to rotate, thereby driving the sliding door 2 to swing. Wherein the driving device 5 may be a driving motor. When the first transmission member 42 is a gear, the driving motor is disposed below the first transmission arm 41, a housing of the driving motor is fixed to the first transmission arm 41, and a motor shaft of the driving motor passes through the first transmission arm 41 and then is fixedly connected to the gear. When the driving motor 5 is controlled to rotate, the gear is driven to rotate, and the gear and the rack move relatively to drive the sliding door 2 to swing. In other alternative embodiments, the first transmission member 42 may include a plurality of gears that are engaged with each other to adjust the rotation speed of the driving device 5 so that the sliding door 2 can swing at a proper speed. In the present embodiment, the distance between the first transmission arm 31 and the second transmission arm 41 is greater than the length of the driving device 5, so as to avoid mutual interference when the two move.

In the present embodiment, since the second rail 21 has an L-shaped structure, the second linear rail 212 of the second rail 21 extends to a side close to the sliding door 2. Therefore, a gap is formed between the first linear rail 211 of the second rail 21 and the sliding door 2. The second rail 21 of the present embodiment may be fixedly connected to the sliding door 2 by a fixing plate disposed above the second rail 21, as shown in fig. 4. Preferably, the second transmission assembly 4 further comprises a first limiting member 43 disposed above the first transmission arm 41. The first limiting part 43 and the first transmission part 42 are respectively disposed at two sides of the second track 21, and are used for limiting the first transmission part 42 to move along the second track 21, so as to prevent the first transmission part 42 from being separated from the second track 21 in the moving process. Preferably, the first position limiting member 43 may be configured as a roller rotatably connected to the first transmission arm 41. When the first transmission component 42 moves along the second track 21, the first limiting component 43 rolls along the inner side of the second track 21, so that the problem that the first limiting component 43 is abraded too fast to affect the stability of the sliding door 2 in the moving or swinging process and the service life of the second transmission component 4 is affected can be avoided.

Further, as shown in fig. 2, the second transmission assembly 4 further includes a first support member 44. Preferably, the first supporting member 44 is a roller rotatably connected to the first driving arm 41. The rotation axis of the first supporting part 44 is substantially perpendicular to the rotation axis of the first limiting part 43. The first supporting member 44 is disposed at the bottom of the second rail 21 and is connected to the bottom of the second rail 21 in a rolling manner, so that the bottom of the second rail 21 is prevented from being directly contacted with the first transmission arm 41, and the movement of the first transmission member 42 along the second rail 21, that is, the movement or swing of the sliding door 2, is prevented from being influenced.

In this embodiment, the swing arm sliding door mechanism is provided with an auxiliary support structure. In an alternative embodiment, a support rod is rotatably connected to the first bracket 12, the support rod is provided with a sleeve and a piston, the other end of the support rod is connected to the sliding door 2, the support rod can passively swing around the first bracket 12 during the movement of the sliding door 2, and the piston and the sleeve also axially move along with the support rod to adjust the length of the support rod, so that the sliding door 2 is kept parallel to the mounting frame 1. Through the connection of the first transmission component 3, the second transmission component 4 and the auxiliary support structure with the mounting frame 1 and the sliding door 2, the weight of the sliding door 2 can be borne, so that the sliding door 2 can move smoothly at a certain height. The person skilled in the art may also arrange one or more of said auxiliary support structures in a suitable position, using other structures suitable for following the swinging movements of the sliding door 2.

In another alternative implementation, the first transmission arm 31 may be disposed above the second rail 21. The first transmission member 42 is disposed at one side of the lower portion of the first transmission arm 31 and is in transverse transmission connection with the second rail 21. The first stopper member 43 is provided on the lower side of the first transmission arm 31. The driving device 5 is disposed above the first transmission arm 31, and is fixedly connected to the first transmission member 42 located below the first transmission arm 31 through the through hole of the first transmission arm 31. In the present embodiment, the structure of the second transmission assembly 4, the connection manner between the second transmission assembly 4 and the driving device 5, and the transmission manner between the second transmission assembly 4 and the second rail 21 are the same as those in the above-mentioned implementation, and the difference is only that the second transmission assembly 4 and the driving device 5 are disposed above the second rail 21 in a symmetrical manner to the above-mentioned implementation, and the description is not repeated here.

In the embodiment, since the second rail 21 is fixed on the inner side of the sliding door 2, the first linear rail 211 of the second rail 21 is parallel to the sliding door 2 and the mounting bracket 1, and the distance between the first linear rail 211 and the mounting bracket 1 is adapted to the length of the first transmission arm 41. Thus, as the first transmission member 42 moves relative to the first linear rail 211 of the second track 21, the sliding door 2 translates laterally relative to the mounting bracket 1. Since the second linear rail 212 is perpendicular to the first linear rail 211, that is, the second linear rail 212 is perpendicular to the sliding door 2, and the length of the first transmission arm 41 is fixed. Therefore, when the first transmission member 42 moves from the first linear rail 211 to the second linear rail 212 of the second track 21, the first transmission arm 41 and the first bracket 12 rotate relatively, and at the same time, the first transmission member 42 and the first limiting member 43 drive the sliding door 2 to swing to the side where the mounting bracket 1 is located, so as to ensure that the first transmission member 42 always moves along the second track 21, thereby closing the sliding door 2. When the first transmission member 42 moves from the second linear rail 212 of the second track 21 to the first linear rail 211, the first transmission arm 41 and the first bracket 12 rotate relatively, and the first transmission arm 41 drives the sliding door 2 to swing to a side away from the mounting bracket 1, so as to open the sliding door 2.

In another alternative implementation, the second transmission assembly 4 and the second rail 21 may be disposed below the first transmission assembly 3 and the first rail 11. The structures of the first track 11, the second track 21, the first transmission assembly 3 and the second transmission assembly 4 are completely the same as those of the above implementation mode. Correspondingly, the height of the rotary connection part of the first transmission component 3 and the sliding door 2 is adapted to the height of the first track 11, and the height of the rotary connection part of the second transmission component 4 and the first bracket 12 is adapted to the height of the second track 21, so that the first transmission component 3 and the second transmission component 4 can move along the corresponding tracks, and further the sliding door 2 can be opened or closed.

The driving device 5 is in transmission connection with the second transmission assembly 4 and configured to controllably drive the second transmission assembly 4 to move along the second track 21 so as to drive the sliding door 2 to move or swing. Specifically, the driving device 5 may be a driving motor, a housing of the driving motor is fixedly connected to the first transmission arm 41 in the second transmission assembly 4, and a driving shaft of the driving motor passes through a through hole at a corresponding position of the first transmission arm 41 and is fixedly connected to the gear (when the first transmission member 42 is a gear). When the driving motor is controlled to rotate, the gear fixedly connected with the driving motor is driven to rotate, the gear is meshed with the rack (the second track 21) for transmission, and the gear moves along the rack relatively. Because the rack is fixed on the sliding door 2, and the gear can only rotate relative to the mounting rack 1, when the gear and the rack move relatively, the rack drives the sliding door 2 to move relative to the gear, and then the movement of the sliding door 2 is driven and controlled. In other alternative implementations, the driving device 5 can be any other device that can drive the second transmission assembly 4 to move along the second track 21.

The swing arm sliding door mechanism of the present embodiment further includes a control device 6 (not shown in the drawings). The control device 6 is in communication connection with the driving device 5, and is used for controlling the driving device 5 to drive the second transmission assembly 4 to move along the second track 21 so as to drive the sliding door 2 to swing or move, thereby realizing the opening or closing of the sliding door 2. Preferably, the swing arm sliding door mechanism is further provided with a signal receiving device, connected to the control device 6, and configured to receive a signal sent by a user to open or close the sliding door, and send the received signal to the control device 6 for control.

The motion process of the swing arm sliding door mechanism of the embodiment comprises the following steps:

when the sliding door 2 is in the closed state, as shown in fig. 2, the sliding door 2 is flush with the top of the mounting bracket 1, the first transmission member 42 is located at the end of the second linear rail 212 of the second rail 21, and the second transmission member 32 is located at the end of the fourth linear rail 112 of the first rail 11.

When the sliding door 2 needs to be opened, the user sends a command to the driving device 5 through the control device 6, and the driving device 5 is controlled to drive the first transmission member 42 to rotate at a preset rotating speed, and the first transmission member 42 and the second track 21 are in meshed transmission. When the first transmission member 42 moves from the end of the second linear rail 212 of the second rail 21 to the first linear rail 211 along the first arc-shaped rail, since one end of the first transmission arm 41 is rotatably connected to the first bracket 12, the distance from the first transmission member 42 to the position where the first transmission arm 41 is rotatably connected to the first bracket 12 is constant during the movement. When the first transmission member 42 moves along the second linear rail 212 of the second track 21 to the first linear rail 211, the first transmission member 42 drives the first transmission arm 41 to rotate and simultaneously drives the sliding door 2 to swing outwards, and when the sliding door 2 swings until the first transmission arm 41 is perpendicular to the sliding door 2 and the mounting frame 1, the sliding door 2 stops swinging. At this time, the first linear rail 211 of the second rail 21 is parallel to the mounting frame 1 and is in transmission connection with the first transmission member 42. The first transmission component 42 is in transmission connection with the first linear rail 211 of the second rail 21, and the sliding door 2 is translated outwards under the action of the second rail 21 until the first transmission component 42 is transmitted to the tail end of the first linear rail 211 of the second rail 21, so that the sliding door 2 completes the opening action.

In the embodiment, during the controlled outward swinging process of the sliding door 2, that is, during the process that the first transmission member 42 drives the first transmission arm 41 to rotate and simultaneously drives the sliding door 2 to swing outward, one end of the second transmission arm 31 is rotatably connected to the sliding door 2, and the second transmission member 32 at the other end of the second transmission arm 31 is located at the end of the first track 11. At this time, the sliding door 2 drives the second transmission arm 31 to rotate, and further drives the second transmission member 32 to move from the end of the fourth linear rail 112 of the first rail 11 along the second arc-shaped rail to the third linear rail 111. The second transmission arm 31 and the second transmission member 32 are used to assist the first transmission arm 41 and the first transmission member 42 to control the sliding door 2 to swing and move, so that the sliding door 2 can smoothly swing or move, completing the opening operation.

When the sliding door 2 needs to be closed, a user sends a command to the driving device 5 through the control device 6, the driving device 5 is controlled to drive the first transmission member 42 to rotate at a predetermined rotation speed, at this time, the first transmission member 42 and the second track 21 are in meshed transmission, and the first transmission member 42 moves towards the tail end of the second linear track 212 along the first linear track 211. This process includes the sliding door 2 moving in parallel along the first linear rail 211 and the sliding door 2 swinging along the first arcuate rail. Specifically, the first linear rail 211 is parallel to the mounting frame 1, and when the first transmission member 42 moves relatively in parallel along the first linear rail 211, the sliding door 2 moves laterally relative to the mounting frame 1, and at the same time, the second transmission member 32 is driven to move laterally along the third linear rail 111 of the first rail 11. When the first transmission member 42 moves to the connection of the first and second

linear rails

211 and 212, i.e., the first arc-shaped rail, the second transmission member 32 moves to the connection of the third and fourth

linear rails

111 and 112, i.e., the second arc-shaped rail. When the first transmission component 42 continues to move along the second linear rail 212, the sliding door 2 is driven to swing towards one side of the mounting rack 1, and the sliding door 2 drives the first transmission component 42 to continue to move along the fourth linear rail 112, so that the sliding door 2 is aligned with the top of the mounting rack 1, and the sliding door is closed.

Fig. 6 is a schematic structural view of a clutch mechanism according to an embodiment of the present invention. The swing arm sliding door mechanism of the present embodiment may further include a clutch mechanism 8. As shown in fig. 6, the clutch mechanism 8 may be connected to a transmission assembly as an active assembly, the clutch mechanism 8 may include a connecting rod 81 and a reset device 82, and one end of the connecting rod 81 may be rotatably connected to a corresponding transmission arm, for example, may be connected to the transmission arm in an articulated manner. The other end of the connecting rod 81 is rotatably connected to the rotating shaft of one transmission member 9, and in case the transmission assembly comprises a plurality of transmission members, it can be connected to the transmission member 9 in the intermediate position. The rotating shaft of the transmission part 9 and the rotating shafts of the transmission parts at the upper stage and the lower stage are not in the same straight line, so that the transmission part 9 is convenient to disengage for transmission. When an emergency occurs, the connecting rod 81 can be pulled to stop the meshing transmission of the transmission assembly, so that the sliding door can be pushed open quickly, and the danger caused by the motor being blocked due to the violent pushing of the sliding door is prevented. The restoring mechanism 82 may be a spring, one end of which is connected to the connecting rod 81, and the other end of which is connected to a transmission arm or the like, and the spring supports the connecting rod 81 and the transmission member 9 connected to the connecting rod 81, so that the transmission member 9 maintains normal engagement transmission in a state where the clutch mechanism 8 is not applied with an external force. The clutch mechanism 8 is additionally arranged, so that partial transmission parts in the transmission assembly can be separated from the transmission chain when the sliding door needs to be opened by bare hands in emergency, and the phenomenon that the sliding door cannot be opened due to motor stalling and jamming is prevented.

The swing arm of the swing arm sliding door mechanism of this embodiment's one end and the door that slides rotationally are connected, and the other end is movably connected with the first track of mounting bracket, and the one end and the mounting bracket of second transmission subassembly rotationally are connected, and the other end is movably connected with the second track of swing arm sliding door, and drive arrangement is connected as the transmission of one side of driving part in first transmission subassembly or the second transmission subassembly, makes the driving part along the orbital movement that corresponds, in order to drive first transmission subassembly the one side of being the follower in the second transmission subassembly moves along the track that corresponds to make sliding door remove along predetermined route, realize opening or closing of sliding door. The swing arm sliding door mechanism disclosed by the embodiment of the invention has the advantages of simple overall structure, reliable matching, high transmission efficiency, large opening degree and small occupied space of a vehicle body, and can well realize the automatic control of the swing arm sliding door.

Example two:

fig. 7 and 8 are schematic structural views of the swing arm sliding door mechanism of the present embodiment. As shown in fig. 7 and 8, the swing arm sliding door mechanism of the present embodiment differs from the swing arm sliding door mechanism of the first embodiment in that the sliding door 2 of the present embodiment includes two

second rails

21a, 21 b. The two

second rails

21a, 21b are arranged in parallel along the height direction of the sliding door 2, and are respectively disposed at the top and the bottom of the sliding door 2. Correspondingly, the swing arm sliding door mechanism comprises two

second transmission assemblies

4a and 4b which are in transmission connection with the corresponding

second rails

21a and 21b respectively. In the present embodiment, the structures of the

second tracks

21a and 21b and the two

second transmission assemblies

4a and 4b are the same as those of the first embodiment. And will not be repeated here. The swing arm sliding door mechanism of the present embodiment further includes a synchronizing shaft 7. Two ends of the synchronizing shaft 7 are fixedly connected with the first transmission parts 42 of the two

second transmission assemblies

4a and 4b, respectively. In the embodiment, the swing arm sliding door mechanism has only one driving device 5, and the driving device 5 is in transmission connection with a second transmission assembly 4a positioned at the top of the mounting frame 1. When the driving device 5 drives the second transmission assembly 4a to move along the second track 21a, the second transmission assembly 4a synchronously transmits the driving force to the second transmission assembly 4b through the synchronizing shaft 7, so as to synchronously drive the second transmission assembly 4b to move along the second track 21b, and further realize the driving control of the sliding door 2. Alternatively, the driving device 5 may also be in transmission connection with the second transmission assembly 4b located at the bottom of the mounting frame 1. When the driving device 5 drives the second transmission assembly 4b to move along the second track 21b, the second transmission assembly 4b synchronously transmits the driving force to the second transmission assembly 4a through the synchronous shaft 7, so as to synchronously drive the second transmission assembly 4a to move along the second track 21a, and further realize the driving control of the sliding door 2. Because the first supporting parts 44 are arranged in the two

second transmission assemblies

4a and 4b, the weight of the sliding door 2 can be stably borne by the two first supporting parts 44, and the

second transmission assemblies

4a and 4b are fixedly connected through the synchronizing shaft 7, so that the sliding door 2 can stably move or swing at a certain height without deflection.

In an alternative embodiment, a plurality of pairs of transmission components such as gear sets or ropes and the like can be arranged on the

first transmission arms

41a and 41b to be connected with the gears meshed with the racks (i.e. the first track 11), so that the transmission is guided to the edge of the mounting frame 1, and then the synchronizing shaft 7 is fixed with the last stage gear or chain wheel, so that the synchronizing shaft 7 is arranged at a position close to the edge of the mounting frame 1, and the whole swing arm sliding door mechanism can be more attractive.

In this embodiment, the structures of the mounting frame 1, the sliding door 2, the

second transmission assemblies

4a and 4b, the driving device 5, the control device 6, and other parts of the swing arm sliding door mechanism are the same as those of the first embodiment, and are not described herein again.

The second track of two parallels about this embodiment is through setting up on the door that slides and set up two and correspond the second transmission assembly that the transmission is connected rather than respectively, and two second transmission assemblies pass through synchronizing shaft fixed connection for the swing arm of this embodiment door mechanism that slides can drive two second transmission assemblies simultaneously through a drive arrangement and remove, realizes the drive control who opens or close the door that slides. Meanwhile, the upper second transmission assembly and the lower second transmission assembly are driven simultaneously, so that the stress of the sliding door is uniform, the sliding door is stably supported, and the sliding door can be opened or closed more effectively and stably.

Example three:

fig. 9 is a schematic structural view of the swing arm sliding door mechanism of the present embodiment. As shown in fig. 9, the swing arm sliding door mechanism of the present embodiment does not include the synchronizing shaft as described in the second embodiment, but includes two

driving devices

5a, 5 b. The two

driving devices

5a and 5b are respectively in transmission connection with the two

second transmission assemblies

4a and 4b, and are respectively used for driving the corresponding

second transmission assemblies

4a and 4b to move along the corresponding

second tracks

21a and 21b so as to drive the sliding door 2 to open or close. In the present exemplary embodiment, the control device 6 of the swing arm sliding door mechanism is connected in communication with the two

drives

5a, 5b, respectively. When the sliding door 2 needs to be controlled to open or close, the control device 6 controls the two

driving devices

5a and 5b to simultaneously drive the corresponding

second transmission assemblies

4a and 4b to synchronously move along the corresponding

second tracks

21a and 21 b. Because the first supporting parts 44 are arranged in the two

second transmission assemblies

4a and 4b, the weight of the sliding door 2 can be stably borne by the two first supporting parts 44, and the two

driving devices

5a and 5b synchronously drive the corresponding

second transmission assemblies

4a and 4b, so that the sliding door 2 can stably and synchronously move or swing at a certain height.

In this embodiment, the structures of the mounting frame 1, the sliding door 2, the first transmission assembly 3, the control device 6, and other parts of the swing arm sliding door mechanism are the same as those of the first embodiment and the second embodiment 2, and are not described herein again.

The embodiment enables the sliding door to be stressed uniformly by synchronously driving the upper and lower second transmission assemblies, and can more effectively and stably open or close the sliding door.

Example four:

fig. 10 is a schematic structural view of the swing arm sliding door mechanism of the present embodiment. As shown in fig. 10, the driving device 5 of the swing arm sliding door mechanism of the present embodiment is in transmission connection with the first transmission assembly 3. In this embodiment, the driving device 5 is controlled to drive the second transmission component 32 to move or rotate, so as to drive the first transmission component 3 and the first rail 11 to move relatively, and drive the second transmission component 4 to move along the second rail 21, so that the sliding door 2 can stably move along a predetermined path, and the sliding door 2 can be opened or closed. The first transmission assembly 3 is provided as a corresponding structure movable along the first track 11, alternatively the first transmission assembly 3 may be provided as a similar structure as the second transmission assembly 4.

Specifically, in this embodiment, the first rail 11 may be a rack structure, and the rack structure is disposed on a side close to the mounting frame 1 and is in transverse meshing transmission connection with the first transmission assembly 3. Correspondingly, the second transmission member 32 comprises at least one gear wheel in meshing transmission with said rack. When the gear is controlled to rotate, the rack and the gear move relatively to realize meshing transmission. Since the rack is fixedly disposed on the top of the second bracket 13, when the rack and the gear move relatively, the sliding door 2 and the gear move relatively, and thus the sliding door 2 is opened or closed.

Further, the first transmission assembly 3 includes a second limiting member 33 disposed below the second transmission arm 31. The second limiting part 33 and the second transmission part 32 are respectively disposed at two sides of the first track 11, and are used for limiting the second transmission part 32 to move along the first track 11, so as to prevent the second transmission part 32 from being separated from the first track 11 during the moving process. Preferably, the second limiting member 33 may be configured as a roller rotatably connected to the second transmission arm 31. When the second transmission member 32 moves along the first track 11, the second limiting member 33 rolls along the inner side (i.e. non-tooth side) of the first track 11, so as to prevent the second limiting member 33 from being worn too fast, which affects the stability of the sliding door 2 during moving or swinging and affects the service life of the first transmission assembly 3.

The driving device 5 is in transmission connection with the first transmission assembly 3 and is configured to controllably drive the first transmission assembly 3 to move along the first track 11 so as to drive the sliding door 2 to move or swing. Specifically, the driving device 5 may be a driving motor, a housing of the driving motor is fixedly connected to the second transmission arm 31 in the first transmission assembly 3, and a driving shaft of the driving motor passes through a through hole at a corresponding position of the second transmission arm 31 and then is fixedly connected to the gear (when the second transmission member 32 is a gear). When the driving motor is controlled to rotate, the gear fixedly connected with the driving motor is driven to rotate, the gear is meshed with the rack (the first track 11) for transmission, and the gear moves along the rack relatively. Since the rack is fixed on the second bracket 13 and the gear is only rotatable relative to the second transmission arm 31, when the gear and the rack move relatively, the gear drives the second transmission arm 31 to move relative to the gear, thereby realizing the movement of the drive control sliding door 2. In other alternative implementations, the driving device 5 can also be provided as any other device that can drive the second transmission assembly 4 to move along the second track 21.

In this embodiment, the structures of the mounting frame 1, the sliding door 2, the second transmission assembly 4, the control device 6, and other parts of the swing arm sliding door mechanism are the same as those of the first to third embodiments, and are not described herein again.

Example five:

the swing arm sliding door mechanism of the first to fourth embodiments can be applied to any required fields, for example, industries such as construction, mobile machinery and the like. That is, the swing arm sliding door mechanism can be used as a door, a bin door, an automobile door, a high-speed rail door, a cabinet door and the like. Preferably, the swing arm sliding door mechanism is applied to the mobile machinery industry. The moving machine comprises a moving machine body and a swing arm sliding door mechanism. The mounting frame of the swing arm sliding door mechanism is fixed on the moving machine body, and the opening or closing of the sliding door of the swing arm sliding door mechanism is controlled to realize the opening or closing of the door of the moving machine.

Fig. 11 to 12 are plan views of the sliding door of the present embodiment during movement and when fully opened, respectively. In another alternative implementation, the moving machine may include two swing arm sliding door mechanisms symmetrically disposed on the moving machine body, as shown in fig. 11 and 12. In this embodiment, the two swing arm sliding door mechanisms may be the same as any one of the first to fourth embodiments.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
