Technical Field
[0001] This application relates to, but is not limited to, the field of vehicle technology, and in particular to a folding mechanism and a vehicle. Background Technology
[0002] To enhance the vehicle's intelligent features, entertainment equipment that can be folded or unfolded relative to the vehicle body is installed inside.
[0003] In related technologies, the folding mechanism will vibrate up and down when encountering bumpy roads. Moreover, when used for folding large screens, the strength of the folding mechanism is insufficient. If the speed reducer mechanism is increased to improve rigidity, the size of the mounting beam will be increased. Summary of the Invention
[0004] The folding mechanism provided in this application can reduce the size of the folding mechanism while improving its stability.
[0005] On one hand, this application provides a folding mechanism, which includes a folding component, a power component, and a locking component. The folding component is movably connected between an entertainment device and a vehicle roof. The folding component includes a first state in which the entertainment device is folded relative to the vehicle roof, and a second state in which the entertainment device is unfolded relative to the vehicle roof. The power component is connected to the folding component and is used to drive the folding component to switch between the first state and the second state. The locking component is connected to the power component, and when the folding component is rotated to the first state, the power component drives the locking component to move, locking or unlocking the folding component relative to the vehicle roof. The folding mechanism disclosed in this application is applied.
[0006] The folding mechanism provided in this application, because the power component is connected to the folding component, can drive the folding component to move relative to the roof. Since the folding component is connected between the entertainment device and the roof, its movement relative to the roof can cause the entertainment device to move relative to the roof. Under the drive of the power component, the folding component can move the entertainment device to a first state of folding relative to the roof, and a second state of unfolding the entertainment device relative to the roof. Because the locking component is connected to the power component, when the folding component rotates to the first state, the power component drives the locking component to move, thus locking or unlocking the folding component relative to the roof. Specifically, when the entertainment device is not in use, after the power component drives the folding component to the first state, the power component can continue to drive the locking component to move, locking the folding component relative to the roof. When the entertainment device needs to be used, the moving component drives the locking component to move, unlocking the folding component relative to the roof, and then the power component continues to drive the folding mechanism to the second state.
[0007] With this structure, the power unit can realize the folding or unfolding of the folding component while also realizing the self-locking or unlocking function of the folding component, reducing the need for a separate mechanism to control the locking component, thereby reducing the size of the folding mechanism; at the same time, the locking component can lock the position of the entertainment equipment relative to the roof when the folding mechanism is folded, which can improve the stability of the folding mechanism.

[0014] In one possible implementation of this application, the force-limiting joint includes a movable sleeve, a fixed sleeve, an elastic element, and a limiting sleeve; one end of the fixed sleeve is connected to the folding assembly, and the other end of the fixed sleeve is movably connected to the movable sleeve; the movable sleeve is connected to the output end of the power assembly; the elastic element is sleeved on the outer periphery of the fixed sleeve, and the end of the elastic element closer to the power assembly abuts against the fixed sleeve; the limiting sleeve is sleeved on the outer periphery of the elastic element, and the end of the limiting sleeve away from the power assembly abuts against the elastic element, and the other end of the limiting sleeve is fixedly connected to at least a portion of the movable sleeve; the power assembly overcomes the elastic force of the elastic element to drive the movable sleeve to move the first locking element.

The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0026] To enhance the vehicle's intelligent features and improve the user's entertainment experience while riding in the car, entertainment devices that can be folded or unfolded relative to the vehicle body are installed inside. When in use, folding the entertainment devices reduces space occupation, while unfolding them allows users to watch movies, play promotional videos, or play meeting materials while riding in the car.
[0027] In related technologies, automotive ceiling-mounted screens are small in size and lightweight, with relatively simple folding mechanisms; a single rotating mechanism can meet the usage requirements. However, with the development of smart cockpits, interior designers are demanding a completely new ceiling-mounted screen effect, for example, a screen no smaller than 22 inches, a mounting beam as thin and narrow as possible, and folding functionality.
[0028] In related technologies, the folding mechanism will vibrate up and down when encountering bumpy roads. Moreover, when used for folding large screens, the strength of the folding mechanism is insufficient. If the speed reducer mechanism is increased to improve rigidity, the size of the mounting beam will be increased.
[0029] This application provides a folding mechanism, referring to... Figures 1 to 7 The folding mechanism includes a folding component 1, a power component 2, and a locking component 3. The folding component 1 is movably connected between the entertainment device 4 and the roof 5. The folding component 1 includes a first state in which the entertainment device 4 is folded relative to the roof 5, and a second state in which the entertainment device 4 is unfolded relative to the roof 5. The power component 2 is connected to the folding component 1 and is used to drive the folding component 1 to switch between the first state and the second state. The locking component 3 is connected to the power component 2. When the folding component 1 is rotated to the first state, the power component 2 drives the locking component 3 to move, locking or unlocking the folding component 1 relative to the roof 5. The folding mechanism disclosed in this application is applied.
[0030] In the embodiments of this application, reference is made to Figure 3 and Figure 4 The folding assembly 1 includes a first state in which the entertainment device 4 is folded relative to the roof 5. The first state can also be understood as the folded state of the folding assembly 1. In the first state, the entertainment device 4 is folded up by the folding assembly 1 and close to the roof 5. The entertainment device 4 and the roof 5 are in a relatively parallel position. At this time, the entertainment device 4 is in a hidden or minimal space-occupying state.
[0031] In the embodiments of this application, reference is made to Figure 6 and Figure 7 The second state can also be understood as the unfolded state of the folding component 1. In the second state, there is an angle between the entertainment device 4 and the roof 5. The entertainment device 4 is unfolded relative to the roof 5 and is located within the user's field of vision.
[0032] In this embodiment of the application, during the process of switching the folding component 1 from the first state to the second state, the movement of the folding component 1 can be either rotational or translational.
[0033] In this embodiment, the entertainment device 4 can be a display device, an audio entertainment device, or an interactive device, etc., and this application does not limit it in this way. For example, the entertainment device 4 can be an LCD screen. When the folding component 1 moves to the second state, the LCD screen can be used to play videos (movies, animations, live broadcasts), display navigation information, or read e-books, etc.
[0034] In this embodiment of the application, the power component 2 provides driving force for the folding component 1 to switch between the first state and the second state. The power component 2 can be a power motor or a pneumatic device, etc.
[0035] In this embodiment of the folding mechanism, since the power component 2 is connected to the folding component 1, the power component 2 can drive the folding component 1 to move relative to the roof 5. Since the folding component 1 is connected between the entertainment device 4 and the roof 5, the movement of the folding component 1 relative to the roof 5 can drive the entertainment device 4 to move relative to the roof 5. Under the drive of the power component 2, the folding component 1 can drive the entertainment device 4 to a first state of folding relative to the roof 5, and a second state of unfolding the entertainment device 4 relative to the roof 5. Since the locking component 3 is connected to the power component 2, when the folding component 1 is rotated to the first state, the power component 2 drives the locking component 3 to move, which can lock or unlock the folding component 1 relative to the roof 5. Specifically, when the entertainment device 4 is not in use, after the power component 2 drives the folding component 1 to move to the first state, the power component 2 can continue to drive the locking component 3 to move, locking the folding component 1 relative to the roof 5; when the entertainment device 4 needs to be used, the moving component drives the locking component 3 to move, unlocking the folding component 1 relative to the roof 5, and then the power component 2 continues to drive the folding mechanism to move to the second state.
[0036] With this structure, the power component 2 can realize the folding or unfolding of the folding component 1, as well as the self-locking or unlocking function of the folding component 1, reducing the need for a separate control mechanism for the locking component 3, thereby reducing the size of the folding mechanism; at the same time, the locking component 3 can lock the position of the entertainment device 4 relative to the roof 5 when the folding mechanism is folded, which can improve the stability of the folding mechanism.
[0037] In some possible embodiments of this application, reference is made to Figure 4 , Figure 5 and Figure 7The folding assembly 1 includes a first link assembly 11, which includes a first link 111, a second link 112, a third link 113, and a fourth link 114 that are rotatably connected in sequence. The first link 111 is used to connect to the roof 5, and the fourth link 114 is used to install the entertainment equipment 4. The first link 111 and the fourth link 114 are rotatably connected through a first pivot 13, and the second link 112 and the third link 113 are rotatably connected through a second pivot 14. The power assembly 2 is connected to the first pivot 13 and the second pivot 14 respectively, and the power assembly 2 is used to drive the first pivot 13 and the second pivot 14 to move closer or further apart.
[0038] In this embodiment of the application, the first connecting rod 111 is used to connect the roof 5. The first connecting rod 111 can be disposed on the roof, as shown in the reference. Figure 1 and Figure 2 The first link 111 can also be the crossbeam of the roof 5. The first link 111 remains stationary relative to the roof 5 during the movement of the folding assembly 1.
[0039] In this embodiment, during the switching process between the first and second states of the folding assembly 1, the dimensions of the first link 111, the second link 112, the third link 113, and the fourth link 114 do not change. The first pivot 13 and the second pivot 14 are relatively close or far apart. The included angle between the first link 111, the second link 112, the third link 113, and the fourth link 114 changes through the rotatable connection point. When the angle of the fourth link 114 relative to the first link 111 changes, the entertainment device 4 rotates relative to the roof 5.
[0040] Reference Figure 6 and Figure 7 During the process of the first pivot 13 and the second pivot 14 approaching each other, the included angle between the first link 111 and the fourth link 114 increases, the included angle between the second link 112 and the third link 113 increases, the included angle between the first link 111 and the second link 112 decreases, and the included angle between the third link 113 and the fourth link 114 decreases, and the folding assembly 1 moves from the first state to the second state.
[0041] Reference Figure 3 and Figure 4 During the process of the relative distance between the first pivot 13 and the second pivot 14, the included angle between the first link 111 and the fourth link 114 decreases, the included angle between the second link 112 and the third link 113 also decreases, the included angle between the first link 111 and the second link 112 increases, the included angle between the third link 113 and the fourth link 114 increases, and the folding assembly 1 moves from the second state to the first state.
[0042] In this embodiment, the first link 111, the second link 112, the third link 113 and the fourth link 114 are rotatably connected in sequence. The rotatable connection can be achieved by means of hinge, universal joint or gear connection, etc., and this application does not limit the specific type of connection.
[0043] In the embodiments of this application, reference is made to Figure 4 In the folded state, the first link 111, the second link 112, the third link 113 and the fourth link 114 maintain a parallel relationship and fit together, which can reduce the size between the roof 5 and the entertainment equipment 4, or it can be understood as reducing the size of the folding component 1 in the height direction Z of the vehicle.
[0044] In this embodiment, the first side of the entertainment device 4 is connected to the fourth link 114, and the second side opposite to the first side can rotate relative to the first side under the drive of the folding assembly 1. The first link 111, the second link 112, the third link 113 and the fourth link 114 form a four-link structure. Therefore, the size of the first link 111 has little impact on the rotation angle of the entertainment device 4. Thus, the size of the first link 111 can be reduced, which is equivalent to reducing the size of the folding mechanism on the roof 5, realizing the miniaturization of the large screen folding structure, meeting the requirements of the narrow and thin crossbeam of the roof 5, and making the roof 5 panoramic view more transparent.
[0045] In some possible embodiments of this application, reference is made to Figure 5 , Figure 8 and Figure 9 The folding assembly 1 also includes a second link assembly 12, which includes a fifth link 121 and a sixth link 122. The fifth link 121 and the sixth link 122 are rotatably connected via a third pivot 15. The end of the fifth link 121 away from the sixth link 122 is rotatably connected to a first pivot 13, and the end of the sixth link 122 away from the fifth link 121 is rotatably connected to a second pivot 14. The extension direction of the third pivot 15 is different from the extension directions of the first pivot 13 and the second pivot 14. A power assembly 2 is connected to the third pivot 15 and is used to drive the fifth link 121 and the sixth link 122 to rotate relative to each other.
[0046] In this embodiment of the application, the second link assembly 12 is used to change the distance between the first rotating shaft 13 and the second rotating shaft 14, so that the first rotating shaft 13 and the second rotating shaft 14 are closer to each other or further apart.
[0047] In the embodiments of this application, reference is made to Figure 8 and Figure 9The extension direction of the third pivot 15 is different from that of the first pivot 13 and the second pivot 14. By moving around the two pivots in different directions, the folding assembly 1 can move in different spatial directions. For example, the first pivot 13 and the second pivot 14 extend along the width direction X of the vehicle, and the third pivot 15 extends along the height direction Z of the vehicle.
[0048] In this embodiment, the fifth link 121 and the sixth link 122 can rotate around the third pivot 15, thereby changing the angle between the fifth link 121 and the sixth link 122. Since the fifth link 121 is also connected to the first pivot 13 and the sixth link 122 is also connected to the second pivot 14, the change in the angle between the fifth link 121 and the sixth link 122 can make the first pivot 13 and the second pivot 14 move closer or further apart from each other.
[0049] Reference Figure 7 and Figure 8 When the angle between the fifth link 121 and the sixth link 122 decreases, the fifth link 121 pulls the first pivot 13, and the sixth link 122 pulls the second pivot 14, bringing the first pivot 13 and the second pivot 14 closer together, thus unfolding the folding assembly 1; (Refer to...) Figure 4 and Figure 9 When the angle between the fifth link 121 and the sixth link 122 increases, the fifth link 121 pushes the first pivot 13, and the sixth link 122 pushes the second pivot 14, causing the first pivot 13 and the second pivot 14 to move away from each other, and the folding assembly 1 folds.
[0050] In this embodiment of the application, a connecting shaft 18 is sleeved on the first rotating shaft 13 and the second rotating shaft 14. The fifth connecting rod 121 is hinged to the first rotating shaft 13 through the connecting shaft 18 on the first rotating shaft 13; the sixth connecting rod 122 is hinged to the second rotating shaft 14 through the connecting shaft 18 on the second rotating shaft 14.
[0051] The folding mechanism of this application embodiment can control the movement between the first rotating shaft 13 and the second rotating shaft 14 through the second linkage assembly 12, and can also limit the movement between the first rotating shaft 13 and the second rotating shaft 14, thereby improving the stability of the first rotating shaft 13 and the second rotating shaft 14 during the process of approaching and moving away from each other.
[0052] In some possible embodiments of this application, reference is made to Figure 8 , Figure 9 and Figure 10 The second linkage assembly 12 includes two components, which are respectively disposed at both ends of the power assembly 2. The power assembly 2 extends or shortens along the extension direction of the first rotating shaft 13 to switch the folding assembly 1 between the first state and the second state.
[0053] In this embodiment of the application, the power component 2 is connected to the third rotating shaft 15 of the second link assembly 12. The power component 2 is used to drive the third rotating shaft 15 to move in the extension direction of the first rotating shaft 13, so that the fifth link 121 and the sixth link 122 can rotate around the third rotating shaft 15.
[0054] In this embodiment, the second linkage assembly 12 includes two components. The two second linkage assemblies 12 are symmetrically arranged at both ends of the power assembly 2 along a direction perpendicular to the first rotating shaft 13, so that the power assembly 2 can be connected to the folding assembly 1. At the same time, when the power assembly 2 extends or shortens along the extension direction of the first rotating shaft 13, the two ends of the power assembly 2 can simultaneously push or pull the third rotating shaft 15 of the two linkage assemblies, so that the angles of the fifth link 121 and the sixth link 122 in the two linkage assemblies change.
[0055] In the folding mechanism of this embodiment, two second linkage assemblies 12 are respectively disposed at both ends of the power assembly 2, so that the first rotating shaft 13 and the second rotating shaft 14 are subjected to force evenly, reducing the wear caused by unilateral drive. At the same time, the two second linkage assemblies 12 work together to offset the problem of asynchronous movement caused by processing errors or assembly gaps, thereby improving the smoothness of the folding process of the folding assembly 1.
[0056] In another embodiment, refer to Figure 5 The second linkage assembly 12 includes four components. Two second linkage assemblies 12 form a group, and the two groups of second linkage assemblies 12 are respectively located at both ends of the power assembly 2. The two second linkage assemblies 12 in each group are located on opposite sides of the power assembly 2 along the extension direction of the third rotating shaft 15. This structure makes the first rotating shaft 13 and the second rotating shaft 14 bear forces evenly, improving the stability and smoothness of the folding assembly 1 during the folding or unfolding process.
[0057] In some possible embodiments of this application, reference is made to Figure 5 and Figure 8 There are multiple fourth links 114, with at least two fourth links 114 respectively disposed on both sides of the second link assembly 12 along the extension direction of the first rotating shaft 13; there are multiple second links 112 and multiple third links 113, and each of them is disposed in a one-to-one correspondence with multiple fourth links 114.
[0058] In this embodiment, the first rotating shaft 13 connects multiple fourth connecting rods 114 and multiple first connecting rods 111, and the second rotating shaft 14 connects multiple second connecting rods 112 and multiple third connecting rods 113. It should be noted that the multiple first rotating shafts 13 and multiple second rotating shafts 14 are connected via fourth rotating shafts, and the multiple third rotating shafts 15 and multiple fourth rotating shafts are connected via fifth rotating shafts.
[0059] In this embodiment of the application, the first connecting shaft 18 is disposed on the first rotating shaft 13 and is located between the two fourth connecting rods 114, and the second connecting rod assembly 12 is connected to the first rotating shaft 13 through the connecting shaft 18.
[0060] In this embodiment of the folding mechanism, there are multiple fourth links 114, which increases the stability of the connection with the entertainment device 4. Since at least two fourth links 114 are respectively arranged on both sides of the second link assembly 12 along the extension direction of the first rotating shaft 13, two force points can be evenly distributed on both sides of the second link assembly 12, improving the stability of the second link 112 relative to the first rotating shaft 13 during movement. Because there are multiple second links 112 and third links 113, and each corresponds one-to-one with a multiple fourth link 114, the force on the folding assembly 1 during folding or unfolding can be evenly distributed, improving the structural stability. It should be added that the two ends of the first link 111, the second link 112, the third link 113 and the fourth link 114 are used to connect with each other, and the middle has a clearance groove. When the folding assembly 1 is in the first state, the first link 111, the second link 112, the third link 113 and the fourth link 114 are fitted together, and the clearance groove in the middle forms a clearance space. The power assembly 2 is housed in the clearance space, thereby reducing the size of the folding assembly 1 after folding.
[0061] In some possible embodiments of this application, reference is made to Figure 5 The folding mechanism also includes a first support plate 16 and a second support plate 17, a plurality of second links 112 are connected to the first support plate 16, and the first links 111 extend to both sides of the first support plate 16; a plurality of third links 113 are connected to the second support plate 17, and the second links 112 extend to both sides of the second support plate 17.
[0062] In this embodiment, the first support plate 16 provides an installation base for a plurality of second connecting rods 112, and the second support plate 17 provides an installation base for a plurality of third connecting rods 113. The first support plate 16 and the second support plate 17 may be made of materials such as engineering plastics, aluminum alloys, or carbon fiber.
[0063] In this embodiment, the first connecting rod 111 extends to both sides of the first support plate 16, which can be understood as the first support plate 16 covering the first connecting rod 111 along the extension direction of the first connecting rod 111; the second connecting rod 112 extends to both sides of the second support plate 17, which can be understood as the second support plate 17 covering the second connecting rod 112 along the extension direction of the second connecting rod 112.
[0064] In this embodiment of the folding mechanism, the first link 111 is connected to the roof 5, the fourth link 114 is connected to the entertainment device 4, and multiple second links 112 are all connected to the first support plate 16. The first support plate 16 can provide stable support for the multiple second links 112, and multiple third links 113 are all connected to the second support plate 17. The second support plate 17 can provide stable support for the multiple second links 112, thus transforming multiple stress points into overall frame stress, making the structure of the folding assembly 1 more stable.
[0065] In some possible embodiments of this application, reference is made to Figure 5 The locking assembly 3 includes a force limiting joint 31 and a first locking member 32; the force limiting joint 31 is connected to the first locking member 32 and the power assembly 2 respectively; the fourth link 114 or the entertainment device 4 has a second locking member 33; the power assembly 2 is used to drive the force limiting joint 31, which drives the first locking member 32 to move; the first locking member 32 and the second locking member 33 cooperate to lock or unlock.
[0066] In this embodiment of the application, the first locking member 32 is connected to the force limiting joint 31, and the force limiting joint 31 can drive the first locking member 32 to move under the drive of the power component 2.
[0067] In the embodiments of this application, reference is made to Figure 13 and Figure 14 The first locking member 32 includes a locking ring 321. The side of the entertainment device 4 connected to the fourth link 114 has a second locking member 33, which is a locking hook 331. When the folding assembly 1 is in the first state, the entertainment device 4 and the first locking member 32 are parallel. The power assembly 2 drives the force limiting joint 31 to move, causing the locking ring 321 to engage with the locking hook 331. The locking ring 321 and the locking hook 331 cooperate to limit the position of the entertainment device 4 in the height direction Z and the length direction Y of the vehicle, thereby increasing the stability of the entertainment device 4 after folding.
[0068] In this embodiment, after the power component 2 drives the first locking member 32 and the second locking member 33 to lock together, the power component 2 is de-energized, so that the first locking member 32 and the second locking member 33 remain in the locked state.
[0069] It should be added that, for reference Figure 13 and Figure 14 The locking assembly 3 also includes a reset member 34. When the first locking member 32 and the second locking member 33 are locked, the first locking member 32 presses the reset member 34, and the reset member 34 stores the restoring force. When it is necessary to unlock the first locking member 32 and the second locking member 33, the power assembly 2 moves and acts together with the restoring force of the reset member 34 on the first locking member 32, so that the first locking member 32 and the second locking member 33 are separated, thereby unlocking.
[0070] In some possible embodiments of this application, reference is made to Figure 15 , Figure 16 and Figure 17 The force-limiting connector 31 includes a movable sleeve 311, a fixed sleeve 312, an elastic element 313, and a limiting sleeve 314. One end of the fixed sleeve 312 is connected to the folding assembly 1, and the other end of the fixed sleeve 312 is movably connected to the movable sleeve 311. The movable sleeve 311 is connected to the output end 21 of the power assembly 2. The elastic element 313 is sleeved on the outer periphery of the fixed sleeve 312, and the end of the elastic element 313 near the power assembly 2 abuts against the fixed sleeve 312. The limiting sleeve 314 is sleeved on the outer periphery of the elastic element 313, and the end of the limiting sleeve 314 away from the power assembly 2 abuts against the elastic element 313. The other end of the limiting sleeve 314 is fixedly connected to at least a portion of the movable sleeve 311. The power assembly 2 overcomes the elastic force of the elastic element 313 to drive the movable sleeve 311 to move the first locking element 32.
[0071] In the embodiments of this application, reference is made to Figure 9 and Figure 10 The movable sleeve 311 of the force limiting joint 31 can move relative to the fixed sleeve 312 under the drive of the power component 2. The end of the limiting sleeve 314 near the power component 2 is fixed to at least part of the movable sleeve 311, and the limiting sleeve 314 can move relative to the fixed sleeve 312 as the movable sleeve 311 moves.
[0072] One end of the elastic element 313 abuts against the end of the fixed sleeve 312 near the power component 2, and the other end of the elastic element 313 abuts against the end of the limiting sleeve 314 away from the power component 2. During the movement of the limiting sleeve 314 relative to the fixed sleeve 312, the limiting sleeve 314 and the fixed sleeve 312 squeeze the elastic element 313. The force used by the power component 2 to drive the movement of the movable sleeve 311 needs to overcome the elastic force of the elastic element 313. The squeezing of the limiting sleeve 314 causes the elastic element 313 to deform, and the movable sleeve 311 and the fixed sleeve 312 undergo relative displacement.
[0073] In the embodiments of this application, reference is made to Figure 11 , Figure 12 , Figure 13 and Figure 14 The first locking member 32 is connected to the movable sleeve 311. During the process of the power component 2 driving the folding component 1 to switch between the first state and the second state, the power component 2 drives the force limiting joint 31 to move relative to each other. When the folding component 1 moves to the first state, the driving force of the power component 2 drives the movable sleeve 311 to move, overcoming the elastic force of the elastic member 313. The movable sleeve 311 drives the first locking member 32 to move, thereby achieving locking.
[0074] It should be added that the power assembly 2 is an electric telescopic rod, and the movable sleeve 311 includes a connecting hole for connecting with the telescopic rod.
[0075] In the folding mechanism of this application embodiment, since the movement of the movable sleeve 311 relative to the fixed sleeve 312 needs to overcome the elastic force of the elastic member 313, the movement of the movable sleeve 311 driving the first locking member 32 requires the force of the power component 2 to reach the pre-tightening force of the elastic member 313. In this way, the action of the power component 2 driving the folding component 1 to fold or unfold can be distinguished from the action of driving the locking component 3 to lock. This can avoid premature locking and also provide a buffer for the movement during the locking phase, reducing wear and abnormal noise caused by the large locking impact between the locking components 3.
[0076] In some possible embodiments of this application, reference is made to Figure 15 , Figure 16 and Figure 17 The movable sleeve 311 includes a limiting member 315, and the fixed sleeve 312 includes a limiting groove 316. When the movable sleeve 311 moves relative to the fixed sleeve 312, the limiting member 315 can move within the limiting groove 316; or, the movable sleeve 311 includes a limiting groove 316, and the fixed sleeve 312 includes a limiting member 315. When the movable sleeve 311 moves relative to the fixed sleeve 312, the limiting member 315 can move within the limiting groove 316.
[0077] In this embodiment, the movable sleeve 311 is provided with a limiting member 315, such as a protrusion or a pin, and the fixed sleeve 312 is provided with a limiting groove 316, such as a sliding groove or a channel. The limiting groove 316 can be a through hole or a semi-closed grass trough.
[0078] In this embodiment, the shape of the limiting groove 316 can be adjusted according to the movement mode of the movable sleeve 311. For example, the shape of the limiting groove 316 can be a straight line, a curve, or a spiral.
[0079] The folding mechanism of this application embodiment, with the limiting member 315 and the limiting groove 316 cooperating, can limit the distance of displacement of the movable sleeve 311 relative to the fixed sleeve 312, and can also limit the rotation of the movable sleeve 311 relative to the fixed sleeve 312 during displacement, reduce movement to avoid overtravel or deviation from the track, has a simple structure, and improves the stability of the force limiting joint 31.
