Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to a hangar cover mechanism, a hangar, and a vehicle. Background Art

[0002] With the rapid development of new energy vehicles, the integration of drones and vehicles to boost the intelligent development of new energy vehicles is a hot topic of competition among automakers. Vehicle-mounted drones, acting as a "third eye" for drivers and passengers, are highly integrated with the vehicle, allowing passengers to control the drone's takeoff and landing from within the vehicle. This has become particularly popular among off-road users. However, to accommodate drones, a hangar with an openable hatch is required. Currently, most hangars use hydraulically powered hatches, which are prone to oil leaks and affect the smooth movement of the hatch. Furthermore, the hatch opening and closing mechanism is bulky and requires numerous parts, resulting in high production costs. Summary of the Invention

[0064] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0066] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0067] The following describes a hangar cover mechanism 100 , a hangar 1000 , and a vehicle 3000 according to an embodiment of the present invention with reference to the accompanying drawings.

[0068] like Figure 1-Figure 3 As shown, a hangar hatch cover mechanism 100 according to an embodiment of the present invention includes: a base 10, a hatch cover 20, a first link mechanism 30 and a driving mechanism.

[0069] The first linkage mechanism 30 includes a first rotating rod 31, which is rotatably connected to the base 10 at a first position 31a of the first rotating rod 31. The hatch 20 is connected to the first rotating rod 31 at a second position 31b. The first rotating rod 31 is suitable for driving the hatch 20 to open or close. A driving 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.

[0070] It can be understood that the movement trajectory of the hatch cover 20 is limited by the first rotating rod 31. When the driving mechanism drives the first rotating rod 31 to rotate, the rotating rod drives the hatch cover 20 to move. The rotating rod is connected to the base 10 at the first position 31a, and its second position 31b rotates around the first position 31a. The movement trajectory of the hatch cover 20 can be close to the movement trajectory of the second position 31b, that is, the hatch cover 20 moves along an arc trajectory during the opening or closing process, which can improve the aesthetics of the hatch cover 20 when it moves and improve the visual effect when the hatch cover 20 is opened or closed.

[0071] Thus, the first rotating rod 31 simultaneously 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 functions as a transmission between the drive mechanism and the hatch cover 20, enabling the drive mechanism to rotate the first rotating rod 31 and, in turn, 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, thereby reducing the size and production cost of the hangar 1000.

[0072] In some embodiments, as Figure 12 As shown, the first position 31 a is one end of the first rotating rod 31 , and the second position 31 b is the other end of the first rotating rod 31 .

[0073] In this way, the distance between the first position 31a and the second position 31b can be increased. 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 movement range of the hatch 20 connected to the second position 31b, so that the hatch 20 has a larger opening when opened.

[0074] In some embodiments, as Figure 12 As shown, 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.

[0075] It can be understood 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 power arm of the lever, and the distance between the second position 31b and the first position 31a is the resistance arm.

[0076] 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, which is beneficial to reducing the driving force required when the driving mechanism drives the first rotating rod 31 to rotate, and the driving mechanism can drive the first rotating rod 31 to rotate more stably, that is, the hatch 20 can move more stably.

[0077] Furthermore, the distance between the third position 31 c and the second position 31 b is between 1.5 times and 3 times the distance between the third position 31 c and the first position 31 a .

[0078] It can be understood that the base 10 and the driving mechanism have a limiting effect on the first position 31a and the third position 31c respectively, the second position 31b is away from the first position 31a and the third position 31c, and 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.

[0079] As a result, 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 ensures the structural stability of the first rotating rod 31 while reducing the driving force required by the driving mechanism to rotate the first rotating rod 31. Furthermore, this reduces or prevents the driving mechanism connected to the third position 31c from obstructing the movement of the hatch 20 connected to the second position 31b.

[0080] In some embodiments, as Figure 1-Figure 5 As shown, the first linkage mechanism 30 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-link mechanism.

[0081] It can be understood that when the first rotating rod 31 drives the hatch cover 20 to rotate, the second rotating rod 32 rotates synchronously under the drive of the hatch cover 20, and 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.

[0082] 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.

[0083] Thus, the first rotating rod 31 and the second rotating rod 32 can simultaneously limit the movement trajectory of the hatch cover 20 relative to the base 10 , thereby improving the stability of the hatch cover 20 when moving relative to the base 10 .

[0084] Furthermore, if Figure 13As shown, the second rotating rod 32 is provided with a weight-reducing hole 321, thereby reducing the mass of the second rotating rod 32. It is understood that the first rotating rod 31 drives the hatch cover 20 to rotate, and the hatch cover 20 further drives the second rotating rod 32 to rotate. In other words, when the driving member 43 drives the first rotating rod 31 to rotate, it needs to overcome the resistance from both the hatch cover 20 and the second rotating rod 32.

[0085] 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 by the driving member 43 to drive the first rotating rod 31 to rotate.

[0086] In some embodiments, as Figure 1-Figure 5 、 Figure 13 As shown, the second rotating rod 32 is a curved rod, and the middle of the second rotating rod 32 is arranged to protrude toward the first rotating rod 31 relative to the line connecting its two ends. As a result, a larger clearance space is created on the side of the second rotating rod 32 away from the first rotating rod 31, thereby reducing or preventing the rotation of the second rotating rod 32 from being blocked by other structures on the side away from the first rotating rod 31, thereby improving the smoothness of the rotation of the second rotating rod 32.

[0087] In some embodiments, as Figure 1-Figure 5 、 Figure 10 and Figure 11 As shown, the driving mechanism includes a second connecting rod assembly 40 and a driving unit. The driving unit is transmission-connected to one end of the second connecting rod assembly 40, and the other end of the second connecting rod 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 connecting rod assembly 40.

[0088] Furthermore, the second connecting rod assembly 40 includes a crank 41 and a transmission rod 42, the driving unit 43 is transmission-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 third position 31c of the first rotating rod 31.

[0089] It can be understood that the position of the driving 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, and the relative position of the third position 31c and the driving unit 43 changes, that is, the distance between the third position 31c and the driving unit 43 changes.

[0090] As a result, the crank 41 and the transmission rod 42 can rotate relative to each other so that the angle between the crank 41 and the transmission rod 42 can change. When the driving unit 43 drives the crank 41 to rotate, the crank 41 drives the transmission rod 42 to move or rotate, causing the transmission rod 42 to move away from the end of the crank 41, so that the transmission rod 42 drives the first rotating rod 31 to rotate at the end away from the crank 41, so as to realize the driving force transmission from the driving unit 43 to the first rotating rod 31.

[0091] At the same time, the position of the first rotating rod relative to the drive unit 43 after rotation changes synchronously with the relative position and angle between the transmission rod 42 and the crank 41, thereby maintaining a stable transmission connection between the drive unit 43, the crank 41, the transmission rod 42 and the first rotating rod 31, and making the driving force transmission path from the drive unit 43 to the hatch cover 20 stable, thereby improving the stability of the movement of the hatch cover 20.

[0092] Preferably, a waterproof coating is provided on the surfaces of the crank 41 and the transmission rod 42 .

[0093] Furthermore, the drive unit 43 includes a drive member 43 and a transmission gear set 44. The drive member 43 is provided with a transmission shaft 431. The transmission gear set 44 includes a driving gear 441 and a driven gear 442 that are meshed with each other. The driving gear 441 is connected to the transmission shaft 431 and rotates synchronously. One end of the crank 41 is connected to the driven gear 442 and rotates synchronously.

[0094] Preferably, the gear ratio of the driving gear 441 to the driven gear 442 is less than 1.

[0095] Therefore, the transmission gear set 44 has the function of reducing speed and increasing torque, thereby increasing the driving force of the driving member 43 on 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 cabin cover 20 to move.

[0096] In the present application, there is no limitation on the type of the driving member 43. Preferably, the driving member 43 is configured as a motor.

[0097] In some embodiments, as Figure 12 、 Figure 14 As shown, a damping bushing 50 is provided at the connection between the transmission rod 42 and the first rotating rod 31 .

[0098] It is understood that the damping bushing 50 can have significant damping in its axial and radial directions, thereby providing a shock-absorbing and buffering effect. Thus, the damping bushing 50 can provide a buffer between the transmission rod 42 and the first rotating rod 31, thereby reducing wear or vibration between the transmission rod 42 and the first rotating rod 31, improving the stability of the transmission rod 42 driving the first rotating rod 31 in rotation, and reducing noise generated when the transmission rod 42 rotates or moves relative to the first rotating rod 31.

[0099] Preferably, the first rotating rod 31 is provided with a mounting hole for the damping bushing 50 at the third position 31 c , and the damping bushing 50 is interference-fitted in the mounting hole.

[0100] exist Figure 15 In the example, the hangar 1000 is used for the vehicle 3000. When the hatch cover 20 is opened or closed during the movement of the vehicle 3000, due to the vibration of the vehicle 3000, the base 10 will also vibrate with the vehicle 3000, so that the damping bushing 50 can absorb the vibration transferred from the base 10 between the first rotating rod 31 and the transmission rod 42, thereby improving the stability of the hatch cover 20 during the opening or closing process.

[0101] In some embodiments, as Figure 12 As shown, the first rotating rod 31 is a curved rod, and 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.

[0102] It is understandable that the directions of the three forces, namely, 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 in a straight line.

[0103] Thus, the center of the first rod segment 311 is bent toward 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 approach the direction of the force acting between the transmission rod 42 and the first rotating rod 31. This reduces the resistance encountered by the transmission rod 42 when driving the first rotating rod 31 to rotate. This improves the smoothness of the first rotating rod 31-driven rotation of the hatch cover 20 and helps reduce the driving force output by the drive unit 43.

[0104] Furthermore, by bending the center of the first rod segment 311 relative to the line connecting the first position 31a and the second position 31b toward the transmission rod 42, when the hatch cover 20 is closed, the angle between the first rotation rod 31 and the base 10 at the first position 31a can be increased, thereby increasing the driving force required to move the hatch cover 20 and improving the positional stability of the hatch cover 20 when closed. In other words, the hatch cover 20 can be more stably maintained in the closed position.

[0105] At the same time, the center of the second rod segment 312 is bent relative to the line connecting the third position 31c and the second position 31b, in a direction away from the transmission rod 42. However, when the hatch cover 20 is fully opened, the angle between the first rotating rod 31 and the hatch cover 20 at the second position 31b can be increased, thereby increasing the driving force required to move the hatch cover 20 and further improving the positional stability of the hatch cover 20 when closed. In other words, the hatch cover 20 can be more stably maintained in the fully open position.

[0106] In some embodiments, as Figures 1-6 As shown, a plurality of first link mechanisms 30 are arranged in groups, and two first link mechanisms 30 in the same group are arranged at opposite sides of the base 10 at intervals along the first direction, and the hatch 20 is arranged on the two first link mechanisms 30 in the same group.

[0107] Thus, the two first link mechanisms 30 can support and drive the hatch cover 20 to rotate at different positions in the first direction, thereby improving the stability of the movement of the hatch cover 20 and the stability of the position of the hatch cover 20 relative to the base 10.

[0108] Furthermore, the two first link mechanisms 30 in the same group are connected to the same driving mechanism, which can reduce the number of driving mechanisms and the space occupied by the driving mechanisms in the hangar 1000, thereby improving the space utilization of the hangar 1000.

[0109] In some embodiments, as Figure 1-Figure 3 As shown, the plurality of first link mechanisms 30 are divided into two groups spaced apart along the second direction. Each group of first link mechanisms 30 is connected to a hatch cover 20 , and the two hatch covers 20 are spliced together along the second direction when closed.

[0110] 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.

[0111] In this way, the moving distance of each hatch cover 20 when opening the hatch cover 20 can be reduced, and during the process of opening the hatch cover 20, the two hatch covers 20 can move along the arc trajectory respectively under the drive of the corresponding first link mechanism 30, thereby improving the visual effect when the hatch cover 20 is opened.

[0112] Preferably, the base 10 is rectangular, and the first direction and the second direction are perpendicular to each other.

[0113] Furthermore, if Figure 9 As shown, the hangar hatch cover mechanism 100 further includes a sealing member 60 . The sealing member 60 is provided on at least one hatch cover 20 . When the two hatch covers 20 are closed, the sealing member 60 is clamped between the two hatch covers 20 .

[0114] Therefore, when the hatch covers 20 are closed, the seal 60 can improve the sealing between the two hatch covers 20, thereby reducing or preventing liquids such as rainwater from entering the hangar 1000 through the gaps between the hatch covers 20, and ensuring the protective effect on the hangar 1000 when the hatch covers 20 are closed.

[0115] In some embodiments, as Figure 7 、 Figure 8 As shown, one hatch cover 20 is provided with a sealing protrusion 21, and the other hatch cover 20 is provided with a sealing groove 32. A sealing member 60 is sleeved on the sealing protrusion 21. When the two hatch covers 20 are closed, the sealing protrusion 21 is located in the sealing groove 32, and the sealing member 60 is sandwiched between the sealing protrusion 21 and the sealing groove 32.

[0116] Thus, when the hatch covers 20 are closed, the seal 60 forms a labyrinth seal structure between the two hatch covers 20, further improving the sealing between the two hatch covers 20. Furthermore, the seal 60 is sleeved onto the sealing protrusion 21 to secure the seal 60 on the hatch covers 20, thereby improving the stability of the seal 60's sealing function.

[0117] In some embodiments, as Figure 1-Figure 3 As shown, a first support column 71 is provided on the base 10 . When the hatch 20 is closed, the first link mechanism 30 abuts against the first support column 71 ; when the hatch 20 is opened, the first link mechanism 30 is separated from the first support column 71 .

[0118] Thus, when the hatch cover 20 is closed, the first support column 71 can provide support for the first linkage 30, reducing or preventing deformation of the first linkage 30 caused by the long-term weight of the hatch cover 20. Furthermore, the first support column 71 can limit the rotation range of the first rotation rod 31, ensuring that the hatch cover 20 stops moving when it is closed.

[0119] In addition, when the hatch cover 20 is opened, the first link mechanism 30 is separated from the first support column 71 , that is, when the hatch cover 20 is in the process of opening or closing, the first support column 71 will not block the first link mechanism 30 .

[0120] In some embodiments, as Figure 1-Figure 3 As shown, a second support column 72 is provided on the base 10 . When the hatch cover 20 is closed, the hatch cover 20 abuts against the second support column 72 ; when the hatch cover 20 is opened, the hatch cover 20 is separated from the second support column 72 .

[0121] Therefore, when the hatch cover 20 is closed, the second support column 72 can provide support for the hatch cover 20 to reduce the supporting force of the first link mechanism 30 on the hatch cover 20, thereby improving the stability of the hatch cover 20 in the closed position while reducing or avoiding the deformation of the first link mechanism 30 caused by bearing the weight of the hatch cover 20 for a long time.

[0122] At the same time, the second support column 72 can also limit the range of movement of the hatch cover 20, ensuring that the hatch cover 20 can stop moving when it is closed. In addition, the second support column 72 will not block the movement of the hatch cover 20 during the process of opening or closing the hatch cover 20.

[0123] In some embodiments, as Figures 1-6 As shown, the base 10 includes a bracket 11 , which is disposed on a corner of the base 10 , and the first link mechanism 30 is rotatably connected to the bracket 11 at a first position 31 a .

[0124] Therefore, the bracket 11 and the first connecting rod mechanism 30 are located in the corner area of the base 10, which can reduce or avoid the vacancy 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.

[0125] exist Figure 1-Figure 5 In the example, the driving mechanism corresponding to the bracket 11 and the first link mechanism 30 are arranged near the edge of the base 10.

[0126] Furthermore, the bracket 11 is a vertical plate extending from the edge of the base 10 , and an outwardly extending extension platform 12 is provided on the edge of the base 10 , and the extension platform 12 is provided corresponding to the bracket 11 .

[0127] It is understood that the brackets 11 are disposed at the corners of the base 10, that is, the brackets 11 are disposed correspondingly to portions of the edge of the base 10. Part of the edge of the base 10 is occupied by the brackets 11, and the rotation range of the first rotating rod 31 easily exceeds the area where the brackets 11 are disposed. 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.

[0128] Therefore, the vertical plate can reduce the area occupied by the bracket 11 on the base 10, and the vertical plate can block the side of the rotating rod, thereby reducing or avoiding the first rotating rod 31 from being hit from the side, protecting the structural stability of the first rotating rod 31 and the stability of the rotation of the first rotating rod 31.

[0129] At the same time, the base 10 is provided with an outwardly extending extension platform 12. By setting the bracket 11 on the extension platform 12, the outward extension of the setting position of the bracket 11 and the first rotating rod 31 can be reduced or avoided, so that the usable area on the base 10 other than that occupied by the first rotating rod 31 maintains a regular shape, which is conducive to improving the space utilization rate in the hangar 1000.

[0130] In addition, when the first rotating rod 31 is located on the extension platform 12 and rotates, when the first rotating rod 31 rotates outside the extension platform 12, the first rotating rod 31 can be located outside the edge of the base 10, that is, the first rotating rod 31 will not block the area on the base 10, thereby improving the utilization rate of different areas on the base 10, which is beneficial to improving the overall space utilization rate of the hangar 1000 and facilitating the miniaturization of the hangar 1000.

[0131] like Figure 1-Figure 3 As shown, a hangar hatch cover mechanism 100 according to an embodiment of the present invention includes: a hatch cover 20, a first link mechanism 30 and a driving mechanism.

[0132] The first link mechanism 30 is connected to the hatch cover 20 to drive the hatch cover 20 to move. The driving mechanism includes a second link assembly 40, which is connected to the first link mechanism 30. When the hatch cover 20 is in the closed position, the second link assembly 40 is in a self-locking state.

[0133] It should be noted that the second connecting rod assembly 40 can employ any known crank-connecting rod mechanism disclosed in the prior art, such as a central crank-connecting rod mechanism, an eccentric crank-connecting rod mechanism, or a primary-secondary connecting rod crank-connecting rod mechanism, with no particular limitation on the specific structural form. In this application, the second connecting rod assembly 40 is driven to rotate at the input end, thereby enabling the output end to drive the first connecting rod mechanism 30 to oscillate back and forth within a certain angular range. By properly configuring the structural parameters of the second connecting rod assembly 40, the two extreme swing positions of the first connecting rod mechanism 30 can be precisely located at the closed and fully open positions of the hatch cover 20.

[0134] In this application, when the hatch cover 20 is in the closed position, the second linkage assembly 40 is in a self-locking state. In other words, when the hatch cover 20 is in the closed position and the power source of the drive mechanism is inoperative, it is difficult to drive the second linkage assembly 40 by pushing the hatch cover 20. This ensures that the hatch cover 20 remains stably in the closed position. If an external force impacts the hatch cover 20 during operation of a vehicle equipped with this hatch cover mechanism 100, it is difficult for the hatch cover 20 to open, thereby maintaining driving safety.

[0135] In some embodiments, as Figure 1-Figure 3 As shown, the hatch cover mechanism further includes a base 10. A first linkage mechanism 30 includes a first rotating rod 31. The first rotating rod 31 has two ends rotatably connected to the base 10 and the hatch cover 20, respectively. The first rotating rod 31 is adapted to drive the hatch cover 20 to open or close. A second linkage assembly 40 has one end rotatably connected to the first rotating rod 31. When the hatch cover 20 is in the closed position, the second linkage assembly 40 is in a self-locking state.

[0136] Thus, the driving mechanism drives the first rotating rod 31 to rotate via the second connecting rod assembly 40, thereby driving the hatch cover 20 to open or close via the first rotating rod 31. When the hatch cover 20 is in the closed position, the second connecting rod assembly 40 is in a self-locking state, fixing the position of the first rotating rod 31, that is, the hatch cover 20 can be more stably maintained in the closed position.

[0137] Furthermore, if Figure 4 As shown, the second connecting rod assembly 40 includes a crank 41 and a transmission rod 42. The drive mechanism includes a drive unit that is drivingly 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.

[0138] It should be noted that when the crank 41 and the transmission rod 42 are not straight rods, it is difficult to completely align the crank 41 and the transmission rod 42 due to their different shapes. When they are substantially aligned along the second direction, the force exerted by the transmission rod 42 on the crank 41 forms a small torque close to or equal to zero, making it difficult to drive the crank 41 to rotate, thereby causing the angle or position between the crank 41 and the transmission rod 42 to be fixed, thereby achieving self-locking of the second connecting rod assembly 40.

[0139] It can be understood that the crank 41 and the transmission rod 42 can rotate relative to each other so that the angle between the crank 41 and the transmission rod 42 can change. When the driving unit 43 drives the crank 41 to rotate, the crank 41 drives the transmission rod 42 to move or rotate, causing the transmission rod 42 to move away from the end of the crank 41, so that the transmission rod 42 drives the first rotating rod 31 to rotate at the end away from the crank 41, so as to realize the driving force transmission from the driving unit 43 to the first rotating rod 31.

[0140] At the same time, the position of the first rotating rod relative to the drive unit 43 after rotation changes synchronously with the relative position and angle between the transmission rod 42 and the crank 41, thereby maintaining a stable transmission connection between the drive unit 43, the crank 41, the transmission rod 42 and the first rotating rod 31, and making the driving force transmission path from the drive unit 43 to the hatch cover 20 stable, thereby improving the stability of the movement of the hatch cover 20.

[0141] Specifically, one end of the crank 41 has a rotation axis, and the driving unit drives the crank 41 to rotate around the rotation axis. When the hatch 20 is in the closed position, in the projection direction of the rotation axis, the line connecting the rotatable connection points at both ends of the transmission rod 42 passes through the rotation axis.

[0142] It should be noted that, in 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.

[0143] Reference Figure 1 For ease of description, the line connecting the rotation center of crank 41 to the hinge point between crank 41 and transmission rod 42 is referred to herein as the first line L1, and the line connecting the hinge points at both ends of transmission rod 42 is referred to as the second line L2. It will be understood that because crank 41 rotates about its rotation axis, first line L1 is always perpendicular to the rotation axis of crank 41. When the line connecting the two ends of transmission rod 42 extends in a direction perpendicular to the rotation axis, second line L2 is also generally perpendicular to the rotation axis. At this point, first line L1 and second line L2 are approximately aligned. At this point, second line L2 passes through the rotation axis.

[0144] At this point, when an external force acts on the hatch cover 20, it drives the first rotating rod 31 to rotate, applying force to the transmission rod 42. The force applied by the transmission rod 42 to the crank 41 acts as a compressive force along the length of the crank 41. The crank 41 is not subjected to any tangential force and is difficult to rotate. Therefore, the second connecting rod assembly 40 is in a self-locking state, ensuring that the hatch cover 20 remains stably in the closed position, enhancing safety.

[0145] The hangar 1000 according to the embodiment of the present invention includes the hangar hatch mechanism 100 of the above embodiment.

[0146] The hangar 1000 of the present application utilizes the hangar hatch mechanism 100 of the aforementioned 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 functions as a transmission between the drive mechanism and the hatch 20, enabling the drive mechanism to rotate the first rotating rod 31 and, in turn, 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, thereby reducing the volume and production costs of the hangar 1000.

[0147] like Figure 15 As shown, a vehicle 3000 according to an embodiment of the present invention includes the hangar 1000 according to the above embodiment.

[0148] The vehicle 3000 of the present application utilizes the hangar 1000 of the aforementioned embodiment. The first rotating rod 31 simultaneously 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 functions as a transmission between the drive mechanism and the hatch cover 20, enabling the drive mechanism to rotate the first rotating rod 31 and, in turn, 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 30 simple and compact, thereby reducing the volume and production cost of the hangar 1000.

[0149] Preferably, the vehicle 3000 includes a vehicle body 2000 , and the hangar 1000 is disposed on top of the vehicle body 2000 .

[0150] Other structures and operations of the hangar cover mechanism 100 , the hangar 1000 , and the vehicle 3000 according to the embodiment of the present invention are well known to those skilled in the art and will not be described in detail here.
