Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0068] In related technologies, in order to carry drones, it is necessary to set up a hangar with an openable and closable hatch on the vehicle to store the drones. Most of the current hangars use hydraulic power to drive the hatch opening and closing, which is prone to oil leakage and affects the stability of the hatch movement. In addition, the hatch opening and closing mechanism is large in size and has many parts, resulting in high production costs for the hangar.

[0069] To address the aforementioned problems, some embodiments of this disclosure provide a hangar hatch mechanism 100, a hangar 1000, and a vehicle 3000.

[0070] The following description, with reference to the accompanying drawings, describes a hangar hatch mechanism 100, a hangar 1000, and a vehicle 3000 according to some embodiments of the present disclosure.

[0071] As shown in Figures 1-3, a hangar hatch mechanism 100 according to some embodiments of the present disclosure includes: a base 10, a hatch 20, a first linkage mechanism 30, and a drive mechanism.

[0072] The first linkage mechanism 30 includes a first rotating rod 31, as shown in Figure 12. The first rotating rod 31 is rotatably connected to the base 10 at a first position 31a of the first rotating rod 31. The hatch 20 is connected to a second position 31b of the first rotating rod 31. The first rotating rod 31 is adapted to drive the hatch 20 to open or close. A drive mechanism is connected to the first rotating rod 31 at a third position 31c of the first rotating rod 31 to drive the first rotating rod 31 to rotate. The third position 31c is located between the first position 31a and the second position 31b.

[0073] Understandably, the movement trajectory of the hatch 20 is limited by the first rotating rod 31. When the drive mechanism drives the first rotating rod 31 to rotate, the first rotating rod 31 drives the hatch 20 to move. The first rotating rod 31 is connected to the base 10 at the first position 31a, and rotates around the first position 31b at the second position 31a. The movement trajectory of the hatch 20 can closely follow the movement trajectory of the second position 31b. That is, the hatch 20 moves along an arc-shaped trajectory during the opening or closing process, which can improve the aesthetics of the hatch 20 when it moves and improve the visual effect of the hatch 20 when it is opened or closed.

[0074] Therefore, the first rotating rod 31 connects the hatch 20, the base 10, and the drive mechanism simultaneously. While defining the movement trajectory of the hatch 20 relative to the base 10, the first rotating rod 31 also acts as a transmission mechanism between the drive mechanism and the hatch 20, causing the drive mechanism to drive the first rotating rod 31 to rotate and thus rotate the hatch 20. This reduces the number of connections or transmission structures between the hatch 20 and the base 10, and between the drive mechanism and the hatch 20, making the structure of the first linkage mechanism 30 simple and compact, which helps to reduce the volume and production cost of the hangar 1000.

[0075] In some embodiments, as shown in FIG12, the first position 31a is one end of the first rotating rod 31, and the second position 31b is the other end of the first rotating rod 31.

[0076] This increases the distance between the first position 31a and the second position 31b. During the rotation of the first rotating rod 31, the rotation radius of the second position 31b relative to the first position 31a is larger, thereby increasing the range of motion of the hatch 20 connected to the second position 31b and allowing the hatch 20 to have a larger opening when opened.

[0077] In some embodiments, as shown in FIG12, the distance between the third position 31c and the second position 31b is greater than the distance between the third position 31c and the first position 31a.

[0078] It is understandable that the first rotating rod 31 forms a lever structure, the first position 31a is the fulcrum of the lever, the distance between the third position 31c and the first position 31a is the effort arm of the lever, and the distance between the second position 31b and the first position 31a is the resistance arm.

[0079] Therefore, by setting the distance between the third position 31c and the second position 31b to be greater than the distance between the third position 31c and the first position 31a, it can be ensured that the resistance arm is greater than twice the power arm. This helps to reduce the driving force required when the drive mechanism drives the first rotating rod 31 to rotate, and the drive mechanism can drive the first rotating rod 31 to rotate more stably, that is, the hatch 20 can move more stably.

[0080] Furthermore, the distance between the third position 31c and the second position 31b is between 1.5 and 3 times the distance between the third position 31c and the first position 31a.

[0081] It is understandable that the base 10 and the drive mechanism have limiting functions for the first position 31a and the third position 31c, respectively. The second position 31b is far away from the first position 31a and the third position 31c. As the distance between the second position 31b and the third position 31c increases, the structural stability of the first rotating rod 31 at the second position 31b decreases.

[0082] Therefore, the distance between the third position 31c and the second position 31b is between 1.5 and 3 times the distance between the third position 31c and the first position 31a. This reduces the driving force required for the drive mechanism to rotate the first rotating rod 31 while ensuring the structural stability of the first rotating rod 31. Furthermore, it reduces or avoids the drive mechanism connected to the third position 31c obstructing the movement of the hatch 20 connected to the second position 31b.

[0083] In some embodiments, as shown in Figures 1-5, the first linkage mechanism 30 further includes a second rotating rod 32. The two ends of the first rotating rod 31 are rotatably connected to the base 10 and the hatch 20, respectively, and the two ends of the second rotating rod 32 are rotatably connected to the base 10 and the hatch 20, respectively. The first rotating rod 31, the second rotating rod 32, the base 10 and the hatch 20 form a four-bar linkage mechanism.

[0084] It is understandable that during the rotation of the hatch cover 20 driven by the first rotating rod 31, the second rotating rod 32 rotates synchronously under the drive of the hatch cover 20. Since the two ends of the second rotating rod 32 are respectively connected to the base 10 and the hatch cover 20, the second rotating rod 32 can also limit the rotation trajectory of the hatch cover 20 relative to the base 10.

[0085] It should be noted that the connection positions of the first rotating rod 31 and the second rotating rod 32 on the hatch 20 are staggered, and the connection positions of the first rotating rod 31 and the second rotating rod 32 on the base 10 are staggered.

[0086] Therefore, the first rotating rod 31 and the second rotating rod 32 can simultaneously limit the movement trajectory of the hatch 20 relative to the base 10, thereby improving the stability of the hatch 20 when it moves relative to the base 10.

[0087] Furthermore, as shown in Figure 13, the second rotating rod 32 is provided with a weight-reducing hole 321, thereby reducing the mass of the second rotating rod 32. It can be understood that the first rotating rod 31 drives the hatch 20 to rotate, and the hatch 20 further drives the second rotating rod 32 to rotate. That is to say, when the driving component 432 (as shown in Figure 4) drives the first rotating rod 31 to rotate, it needs to overcome the resistance from the hatch 20 and the second rotating rod 32 at the same time.

[0088] Therefore, by reducing the mass of the second rotating rod 32, the resistance encountered when driving the second rotating rod 32 to rotate can be reduced, thereby reducing the driving force required for the driving member 432 to drive the first rotating rod 31 to rotate.

[0089] In some embodiments, as shown in Figures 1-5 and Figure 13, the second rotating rod 32 is a curved rod, and the middle of the second rotating rod 32 protrudes towards the first rotating rod 31 relative to the line connecting its two ends. Therefore, the second rotating rod 32 can form a larger clearance space on the side away from the first rotating rod 31, thereby reducing or avoiding obstruction of the rotation of the second rotating rod 32 by other structures on the side away from the first rotating rod 31, and improving the smoothness of the rotation of the second rotating rod 32.

[0090] In some embodiments, as shown in Figures 1-5, 10, and 11, the driving mechanism includes a second linkage assembly 40 and a driving unit 43. The driving unit 43 is drively connected to one end of the second linkage assembly 40, and the other end of the second linkage assembly 40 is rotatably connected to the third position 31c of the first rotating rod 31. Thus, the driving unit drives the first rotating rod 31 to rotate via the second linkage assembly 40.

[0091] Furthermore, the second connecting rod assembly 40 includes a crank 41 and a transmission rod 42. The drive unit 43 is connected to one end of the crank 41 to drive the crank 41 to rotate. The other end of the crank 41 is rotatably connected to one end of the transmission rod 42. The other end of the transmission rod 42 is rotatably connected to the third position 31c of the first rotating rod 31.

[0092] It is understandable that the position of the drive unit 43 on the base 10 is fixed, and the third position 31c of the first rotating rod 31 rotates around the first position 31a. The relative position of the third position 31c and the drive unit 43 changes, that is, the distance between the third position 31c and the drive unit 43 changes.

[0093] Thus, the crank 41 and the transmission rod 42 can rotate relative to each other, allowing the angle between them to change. When the drive unit 43 drives the crank 41 to rotate, the crank 41 drives the transmission rod 42 to move or rotate, causing the end of the transmission rod 42 away from the crank 41 to move. As a result, the transmission rod 42 drives the first rotating rod 31 to rotate at the end away from the crank 41, thereby realizing the transmission of driving force from the drive unit 43 to the first rotating rod 31.

[0094] Furthermore, the position of the first rotating rod 31 relative to the drive unit 43 changes synchronously with the relative position and included angle of the transmission rod 42 and the crank 41, thereby maintaining the stable transmission connection between the drive unit 43, the crank 41, the transmission rod 42 and the first rotating rod 31, keeping the driving force transmission path from the drive unit 43 to the hatch 20 stable, and improving the stability of the movement of the hatch 20.

[0095] In some embodiments, the surfaces of the crank 41 and the drive rod 42 are provided with a waterproof coating.

[0096] Furthermore, the drive unit 43 includes a drive member 432 and a transmission gear set 44. The drive member 432 is provided with a transmission shaft 431, and the transmission gear set 44 includes a meshing drive gear 441 and a driven gear 442. The drive gear 441 is connected to the transmission shaft 431 and rotates synchronously, and one end of the crank 41 is connected to the driven gear 442 and rotates synchronously.

[0097] In some embodiments, the gear ratio of the driving gear 441 relative to the driven gear 442 is less than 1.

[0098] Therefore, the transmission gear set 44 has the function of reducing speed and increasing torque, thereby increasing the driving force of the drive component 432 on the rotation of the first rotating rod 31 and reducing the rotation speed of the first rotating rod 31, thereby improving the stability of the first rotating rod 31 driving the hatch 20 to move.

[0099] This disclosure does not limit the type of the drive element 432. For example, the drive element 432 may be a motor.

[0100] In some embodiments, as shown in Figures 12 and 14, a damping bushing 50 is provided at the connection between the transmission rod 42 and the first rotating rod 31.

[0101] Understandably, the damping bushing 50 has significant damping in both its axial and radial directions, thus providing a shock absorption and buffering effect. Therefore, the damping bushing 50 provides buffering between the transmission rod 42 and the first rotating rod 31, thereby reducing wear or vibration between them, improving the stability of the transmission rod 42 driving the first rotating rod 31, and reducing noise generated when the transmission rod 42 rotates or moves relative to the first rotating rod 31.

[0102] In some embodiments, the first rotating rod 31 is provided with a mounting hole for the damping bushing 50 at the third position 31c, and the damping bushing 50 is interference-fitted into the mounting hole.

[0103] In the example of Figure 15, the hangar 1000 is used for the vehicle 3000. When the hatch 20 is opened or closed during the movement of the vehicle 3000, the base 10 will also vibrate with the vehicle 3000 due to the vibration of the vehicle 3000. Thus, the damping bushing 50 can absorb the vibration from the base 10 between the first rotating rod 31 and the transmission rod 42, thereby improving the stability of the hatch 20 during the opening or closing process.

[0104] In some embodiments, as shown in FIG12, the first rotating rod 31 is a curved rod, and the first rotating rod 31 includes a first rod segment 311 located between the first position 31a and the third position 31c, and a second rod segment 312 located between the second position 31b and the third position 31c.

[0105] It is understandable that the directions of the three forces—the force between the transmission rod 42 and the first rotating rod 31, the force between the base 10 and the first rotating rod 31, and the force between the hatch 20 and the first rotating rod 31—are not on a straight line.

[0106] Therefore, by setting the center of the first rod segment 311 to bend towards the transmission rod 42 relative to the line connecting the first position 31a and the second position 31b, the center of the second rod segment 312 is bent away from the transmission rod 42 relative to the line connecting the third position 31c and the second position 31b. The direction of the force transmitted within the first rotating rod 31 can be guided by the extension direction of the rotating rod. The extension direction of the first rotating rod 31 at the third position 31c can be close to the direction of the force between the transmission rod 42 and the first rotating rod 31, thereby reducing the resistance encountered when the transmission rod 42 drives the first rotating rod 31 to rotate, thus improving the smoothness of the first rotating rod 31 driving the hatch 20 to rotate, and also helping to reduce the driving force output by the drive unit 43.

[0107] Furthermore, by setting the center of the first rod segment 311 to be bent toward the transmission rod 42 relative to the line connecting the first position 31a and the second position 31b, when the hatch 20 is closed, the angle between the first rotating rod 31 and the base 10 at the first position 31a can be increased, thereby increasing the driving force required to move the hatch 20, and thus improving the positional stability of the hatch 20 when closed, that is, the hatch 20 can be held more stably in the closed position.

[0108] Furthermore, the center of the second rod segment 312 is bent away from the line connecting the third position 31c and the second position 31b, moving away from the transmission rod 42. When the hatch 20 is fully open, the angle between the first rotating rod 31 and the hatch 20 at the second position 31b is increased, thereby increasing the driving force required to move the hatch 20 and improving the positional stability of the hatch 20 when closed, meaning the hatch 20 can be held more stably in the fully open position.

[0109] In some embodiments, as shown in Figures 1-6, a plurality of first linkage mechanisms 30 are arranged in a group, and two first linkage mechanisms 30 in the same group are spaced apart on opposite sides of the base 10 along a first direction, and the hatch 20 is arranged on the two first linkage mechanisms 30 in the same group.

[0110] Thus, the two first linkage mechanisms 30 can support and drive the hatch 20 to rotate at different positions in the first direction, which can improve the stability of the movement of the hatch 20 and the stability of the position of the hatch 20 relative to the base 10.

[0111] In some embodiments, two first linkage mechanisms 30 in the same group are connected to the same drive mechanism, which can reduce the number of drive mechanisms and reduce the space occupied by the drive mechanisms in the hangar 1000, thereby improving the space utilization of the hangar 1000.

[0112] In some embodiments, as shown in Figures 1-3, the plurality of first linkage mechanisms 30 include two sets of first linkage mechanisms 30 spaced apart along a second direction, each set of first linkage mechanisms 30 being connected to a hatch 20, and the two hatches 20 being spliced ​​together along the second direction when closed.

[0113] It should be noted that when the two hatches 20 are opened, the two hatches 20 move independently in opposite directions in the second direction.

[0114] Therefore, the moving distance of each hatch 20 when opening the two hatches 20 can be reduced, and during the opening process of the two hatches 20, the two hatches 20 can move along the arc trajectory respectively under the drive of the corresponding first linkage mechanism 30, thereby improving the visual effect when the two hatches 20 are opened.

[0115] In some embodiments, the base 10 is rectangular and is arranged perpendicularly to the first and second directions.

[0116] In some embodiments, as shown in FIG9, the hangar hatch mechanism 100 further includes a seal 60 disposed on at least one hatch 20, wherein the seal 60 is sandwiched between the two hatches 20 when both hatches 20 are closed.

[0117] Therefore, when the hatch 20 is closed, the seal 60 can improve the sealing between the two hatches 20, thereby reducing or preventing rainwater and other liquids from entering the hangar 1000 through the gaps between the hatches 20, and ensuring the protection effect of the hatches 20 on the hangar 1000 when they are closed.

[0118] In some embodiments, as shown in Figures 7 and 8, one of the two hatches 20 has a sealing protrusion 21, and the other hatch 20 has a sealing groove 22. A sealing member 60 is fitted onto the sealing protrusion 21. When both hatches 20 are closed, the sealing protrusion 21 is located within the sealing groove 22, and the sealing member 60 is sandwiched between the sealing protrusion 21 and the sealing groove 22.

[0119] Therefore, when the hatch 20 is closed, the seal 60 forms a labyrinth seal structure between the two hatches 20, which can further improve the sealing performance between the two hatches 20. In addition, the seal 60 is fitted onto the sealing protrusion 21 to fix the position of the seal 60 on the hatch 20 and improve the stability of the sealing effect of the seal 60.

[0120] In some embodiments, as shown in Figures 1-3, a first support column 71 is provided on the base 10. When the hatch 20 is closed, the first linkage mechanism 30 abuts against the first support column 71; when the hatch 20 is opened, the first linkage mechanism 30 disengages from the first support column 71.

[0121] Therefore, when the hatch 20 is closed, the first support column 71 can provide support for the first linkage mechanism 30, thereby reducing or avoiding deformation of the first linkage mechanism 30 due to long-term bearing of the weight of the hatch 20. In addition, the first support column 71 can also limit the rotation range of the first rotating rod 31, ensuring that the hatch 20 can stop moving when it is closed.

[0122] Furthermore, when the hatch 20 is opened, the first linkage mechanism 30 disengages from the first support column 71, meaning that the first support column 71 will not obstruct the first linkage mechanism 30 during the opening or closing of the hatch 20.

[0123] In some embodiments, as shown in Figures 1-3, a second support column 72 is provided on the base 10. When the hatch 20 is closed, the hatch 20 abuts against the second support column 72; when the hatch 20 is opened, the hatch 20 disengages from the second support column 72.

[0124] Therefore, when the hatch 20 is closed, the second support column 72 can provide support for the hatch 20, thereby reducing the supporting force of the first linkage mechanism 30 on the hatch 20. This improves the stability of the hatch 20 in the closed position while reducing or avoiding the deformation caused by the first linkage mechanism 30 bearing the weight of the hatch 20 for a long time.

[0125] Furthermore, the second support column 72 can limit the range of movement of the hatch 20, ensuring that the hatch 20 stops moving when closed. And the second support column 72 will not obstruct the movement of the hatch 20 during opening or closing.

[0126] In some embodiments, as shown in Figures 1-6, the base 10 includes a bracket 11, which is disposed on the corner of the base 10, and the first linkage mechanism 30 is rotatably connected to the bracket 11 at a first position 31a.

[0127] Therefore, the bracket 11 and the first linkage mechanism 30 are located in the corner area of ​​the base 10, which can reduce or avoid the empty space of the base 10 in the corner area, make full use of the space at the edge and corner of the base 10, improve the space utilization rate in the hangar 1000, and facilitate the miniaturization of the hangar 1000.

[0128] In the examples of Figures 1-5, corresponding to the bracket 11 and the first linkage mechanism 30, the drive mechanism is located near the edge of the base 10.

[0129] In some embodiments, the bracket 11 is an upright plate extending from the edge of the base 10, and an extension platform 12 extending outward is provided at the edge of the base 10, with the extension platform 12 corresponding to the bracket 11.

[0130] It is understandable that the bracket 11 is located at the corner of the base 10, that is, the bracket 11 is located at a portion of the edge of the base 10. The bracket 11 occupies a portion of the edge of the base 10, and the rotation range of the first rotating rod 31 easily exceeds the area where the bracket 11 is located. When there are multiple brackets 11, the edge area of ​​the base 10 between two brackets 11 is small and easily blocked by the brackets 11 and the first rotating rod 31, making it difficult to utilize.

[0131] Therefore, the upright plate can reduce the area occupied by the bracket 11 on the base 10, and the upright plate can shield the side of the rotating rod, thereby reducing or avoiding the first rotating rod 31 from being hit on the side, protecting the structural stability of the first rotating rod 31 and the stability of the rotation of the first rotating rod 31.

[0132] In addition, the base 10 is provided with an outwardly extending platform 12. By setting the bracket 11 on the extension platform 12, the setting position of the bracket 11 and the first rotating rod 31 can be reduced or avoided from extending outward, so that the usable area on the base 10 other than that occupied by the first rotating rod 31 can maintain a regular shape, which is conducive to improving the space utilization rate within the hangar 1000.

[0133] Furthermore, when the first rotating rod 31 is located on the extension platform 12 and rotates, when the first rotating rod 31 rotates to the outside of the extension platform 12, the first rotating rod 31 can be located on the outer edge of the base 10, that is, the first rotating rod 31 will not obstruct the area on the base 10, thereby improving the utilization rate of different areas on the base 10, which is conducive to improving the overall space utilization rate of the hangar 1000 and the miniaturization of the hangar 1000.

[0134] As shown in Figures 1-3, a hangar hatch mechanism 100 according to some embodiments of the present disclosure includes: a hatch 20, a first linkage mechanism 30, and a drive mechanism.

[0135] The first linkage mechanism 30 is connected to the hatch 20 to drive the hatch 20 to move. The driving mechanism includes a second linkage assembly 40, which is connected to the first linkage mechanism 30. When the hatch 20 is in the closed position, the second linkage assembly 40 is in a self-locking state.

[0136] It should be noted that the second linkage assembly 40 can be a central crank-connecting rod mechanism, an eccentric crank-connecting rod mechanism, a main-secondary connecting rod type crank-connecting rod mechanism, etc., and this disclosure is not limited to its structural form. In some embodiments of this disclosure, the second linkage assembly 40 is used to drive rotation at the input end, thereby driving the first linkage mechanism 30 to reciprocate within a certain angle range at the output end. By reasonably setting the structural parameters of the second linkage assembly 40, the two extreme positions of the swing of the first linkage mechanism 30 can be made to fall precisely at the closed position and the fully open position of the hatch 20.

[0137] In some embodiments of this disclosure, the second linkage assembly 40 is in a self-locking state when the hatch 20 is in the closed position. That is, when the hatch 20 is in the closed position, it is difficult to move the second linkage assembly 40 by pushing the hatch 20 if the power source of the drive mechanism is not activated. This ensures that the hatch 20 remains stably in the closed position. In vehicles with this hatch mechanism 100, if an external force collides with the hatch 20 during operation, it is difficult for the hatch 20 to open, thus maintaining driving safety.

[0138] In some embodiments, as shown in Figures 1-3, the hatch mechanism further includes a base 10. A first linkage mechanism 30 includes a first rotating rod 31, the two ends of which are rotatably connected to the base 10 and the hatch 20, respectively. The first rotating rod 31 is adapted to open or close the hatch 20. One end of a second linkage assembly 40 is rotatably connected to the first rotating rod 31, and the second linkage assembly 40 is in a self-locking state when the hatch 20 is in the closed position.

[0139] Therefore, the drive mechanism drives the first rotating rod 31 to rotate via the second linkage assembly 40, which in turn drives the hatch 20 to open or close. When the hatch 20 is in the closed position, the second linkage assembly 40 is in a self-locking state, fixing the position of the first rotating rod 31, meaning the hatch 20 can be held more stably in the closed position.

[0140] Further, as shown in Figure 4, the second connecting rod assembly 40 includes a crank 41 and a transmission rod 42. The drive mechanism includes a drive unit, which is tractively connected to one end of the crank 41 to drive the crank 41 to rotate. The other end of the crank 41 is rotatably connected to one end of the transmission rod 42, and the other end of the transmission rod 42 is rotatably connected to the first rotating rod 31. When the hatch 20 is in the closed position, the crank 41 and the transmission rod 42 are substantially aligned along the second direction.

[0141] It should be noted that when neither crank 41 nor transmission rod 42 is a straight rod, it is difficult to align crank 41 and transmission rod 42 perfectly due to their different shapes. However, when they are basically aligned along the second direction, the force exerted by transmission rod 42 on crank 41 forms a small torque that is close to or equal to zero, making it difficult to drive crank 41 to rotate. This allows the angle or position between crank 41 and transmission rod 42 to achieve self-locking of the second connecting rod assembly 40.

[0142] It is understandable that the relative rotation of crank 41 and transmission rod 42 allows the included angle between crank 41 and transmission rod 42 to change. When drive unit 43 drives crank 41 to rotate, crank 41 drives transmission rod 42 to move or rotate, causing the end of transmission rod 42 away from crank 41 to move. Thus, the end of transmission rod 42 away from crank 41 drives the first rotating rod 31 to rotate, thereby realizing the transmission of driving force from drive unit 43 to the first rotating rod 31.

[0143] Furthermore, the position of the first rotating rod 31 relative to the drive unit 43 changes synchronously with the relative position and included angle of the transmission rod 42 and the crank 41, thereby maintaining the stable transmission connection between the drive unit 43, the crank 41, the transmission rod 42 and the first rotating rod 31, keeping the driving force transmission path from the drive unit 43 to the hatch 20 stable, and improving the stability of the movement of the hatch 20.

[0144] In some embodiments, one end of the crank 41 has a rotation axis, and the drive unit drives the crank 41 to rotate about the rotation axis. When the hatch 20 is in the closed position, the line connecting the rotatable connection points at both ends of the transmission rod 42 passes through the rotation axis in the projection direction of the rotation axis.

[0145] It should be noted that, along the axial direction of the rotation axis, the line connecting the hinge points at both ends of the transmission rod 42 passes through the rotation axis.

[0146] Referring to Figure 1, for ease of description, the line connecting the center of rotation of crank 41 to the hinge point between crank 41 and transmission rod 42 is called the first connecting line L1, and the line connecting the two hinge points of transmission rod 42 is called the second connecting line L2. It can be understood that since crank 41 rotates about its axis of rotation, the first connecting line L1 is always perpendicular to the axis of rotation of crank 41. When the line connecting the two ends of transmission rod 42 extends in a direction perpendicular to the axis of rotation, the second connecting line L2 is also approximately perpendicular to the axis of rotation. At this time, the first connecting line L1 and the second connecting line L2 are approximately on a straight line. In this case, the second connecting line L2 passes through the axis of rotation.

[0147] At this time, when an external force is applied to the hatch 20, causing the hatch 20 to rotate the first rotating rod 31, thereby applying a force to the transmission rod 42, and the force applied by the transmission rod 42 to the crank 41 is approximately along the length of the crank 41. The crank 41 is not subjected to tangential force and is difficult to rotate. Therefore, the second connecting rod assembly 40 is in a self-locking state at this time, thereby ensuring that the hatch 20 is stably kept in the closed position and improving the safety of use.

[0148] The hangar 1000 according to some embodiments of the present disclosure includes the hatch cover mechanism 100 of the hangar described above.

[0149] The hangar 1000 disclosed herein employs a hatch cover mechanism 100 of the described embodiment. A first rotating rod 31 connects the hatch cover 20, the base 10, and the drive mechanism. While defining the movement trajectory of the hatch cover 20 relative to the base 10, the first rotating rod 31 also acts as a transmission mechanism between the drive mechanism and the hatch cover 20, causing the drive mechanism to drive the first rotating rod 31 to rotate and thus rotate the hatch cover 20. This reduces the number of connections or transmission structures between the hatch cover 20 and the base 10, and between the drive mechanism and the hatch cover 20, making the structure of the first linkage mechanism 30 simple and compact, which helps to reduce the volume and production cost of the hangar 1000.

[0150] As shown in Figure 15, the vehicle 3000 according to some embodiments of the present disclosure includes the hangar 1000 of the above embodiments.

[0151] In the vehicle 3000 disclosed herein, by employing the hangar 1000 of the above embodiment, the first rotating rod 31 simultaneously connects the hatch 20, the base 10, and the drive mechanism. While defining the movement trajectory of the hatch 20 relative to the base 10, the first rotating rod 31 also serves as a transmission mechanism between the drive mechanism and the hatch 20, causing the drive mechanism to drive the first rotating rod 31 to rotate and thus rotate the hatch 20. This reduces the connection or transmission structures between the hatch 20 and the base 10, and between the drive mechanism and the hatch 20, making the structure of the first linkage mechanism 30 simple and compact, which is beneficial for reducing the volume and production cost of the hangar 1000.

[0152] In some embodiments, the vehicle 3000 includes a body 2000 and a hangar 1000 disposed on top of the body 2000.

[0153] Other configurations and operations of the hangar hatch mechanism 100, hangar 1000, and vehicle 3000 according to some embodiments of this disclosure are known to those skilled in the art and will not be described in detail here.
