Description

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 and improve the user's entertainment experience while riding in the vehicle, entertainment devices that can be folded or unfolded relative to the vehicle body are installed inside.

[0003] The folding mechanism in the related technology that drives the entertainment equipment to rotate has a complex structure and occupies a large space in the height direction of the roof after folding. Utility Model Content

[0004] The folding mechanism provided in this application simplifies the structure and reduces the vehicle's height occupation after folding.

[0005] On one hand, this application provides a folding mechanism for mounting entertainment equipment on a vehicle roof. The folding mechanism includes a linkage assembly and an adjustment assembly. The linkage assembly is used to movably connect the entertainment equipment to the vehicle roof and includes a first state in which the entertainment equipment is folded relative to the vehicle roof and a second state in which the entertainment equipment is unfolded relative to the vehicle roof. The adjustment assembly is disposed on the vehicle roof. Along a first direction, both ends of the adjustment assembly are respectively connected to the linkage assembly. The adjustment assembly can extend or shorten along the first direction to drive the linkage assembly to switch between the first state and the second state. The first direction is parallel to the extension plane of the vehicle roof.

[0006] The folding mechanism provided in this application, since both ends of the linkage assembly are connected to the adjusting assembly, allows the adjusting assembly to move along the first direction when it extends, thus increasing the distance between the two ends of the linkage assembly. Conversely, when the adjusting assembly shortens along the first direction, it pulls the two ends of the linkage assembly, shortening the distance between them. This allows the linkage assembly to switch between a first and a second state, folding or unfolding the entertainment device relative to the roof. Thus, by extending and shortening the adjusting mechanism in the first direction, the linkage assembly switches between the first and second states, transforming the complex rotational folding motion into a simple linear motion, simplifying the structure. Because the adjusting mechanism is mounted on the roof, and both ends of the linkage assembly are connected to it, and the adjusting assembly is positioned on the roof along the first direction, which is parallel to the roof's extension plane, the movement of the adjusting mechanism along the first direction effectively means that part of the folding mechanism's structure and the space it moves share the vehicle's height space with the roof. This reduces the vehicle's height space after the folding mechanism is folded.

[0007] In one possible implementation of this application, the adjustment assembly includes a first link and a second link, which are rotatably connected by a first rotating shaft with the axis of the first rotating shaft perpendicular to the roof. The end of the first link away from the second link is rotatably connected to a first end of the link assembly, and the end of the second link away from the first link is driveably connected to a second end of the link assembly.

[0008] In one possible implementation of this application, the first link, the second link, and the first rotating shaft constitute an adjusting link. The adjusting assembly also includes a driving member. There are two adjusting links, and the driving member is disposed between the two adjusting links and is connected to the first rotating shaft of each of the two adjusting links. The driving member can extend or shorten along a second direction to drive the first link and the second link of each of the two adjusting links to rotate around the corresponding first rotating shaft. The second direction is parallel to the extension plane of the roof and perpendicular to the first direction.

[0009] In one possible implementation of this application, the adjusting linkage includes multiple adjusting linkages, which are disposed between the first end and the second end of the linkage assembly. The multiple adjusting linkages are arranged along a second direction, which is consistent with the extension direction of the first end and / or the second end.

[0010] In one possible implementation of this application, the linkage assembly includes a third link and a fourth link, the fourth link being used to mount an entertainment device; the third link and the fourth link are rotatably connected via a second pivot, the end of the third link away from the fourth link being rotatably connected to the second link via the third pivot, and the end of the fourth link away from the third link being rotatably connected to the first link via the fourth pivot, the second pivot, the third pivot, and the fourth pivot extending along a second direction; an adjustment assembly is used to adjust the third pivot and the fourth pivot to be relatively closer or farther apart in the first direction.

[0011] In one possible implementation of this application, the folding mechanism further includes a locking component, which includes a first locking member and a second locking member. The first locking member is disposed on the adjusting component or the linkage assembly, and the second locking member is disposed on the fourth linkage or the entertainment device. When the adjusting component drives the linkage assembly to switch to the first state or the second state, the first locking member and the second locking member cooperate to unlock or lock.

[0012] In one possible implementation of this application, the first locking member includes a locking part, a first connecting part, and a second connecting part. The locking part and the first connecting part are respectively disposed at both ends of the first locking member. The first connecting part is rotatably connected to a third rotating shaft via a fifth rotating shaft. The second connecting part is disposed between the locking part and the first connecting part. The second connecting part is rotatably connected to a second connecting rod via a sixth rotating shaft. The fifth and sixth rotating shafts are axially aligned with the first rotating shaft. When the adjusting assembly extends or shortens along a first direction, the first locking member rotates around the fifth rotating shaft to drive the locking part closer to or away from the second locking member.

[0013] In one possible implementation of this application, the locking assembly further includes an elastic element, one end of which is disposed on the side of the first locking member near the first connecting portion, and the other end of which is disposed on the side of the second connecting rod near the second connecting portion. When the first locking member rotates around the fifth pivot, the first locking member overcomes the elastic force of the elastic element.

[0014] In one possible implementation of this application, the first locking member further includes a snap-fit ​​portion, which includes a snap-fit ​​groove that matches the third rotating shaft. When the first locking member rotates around the fifth rotating shaft to move the locking portion closer to or away from the second locking member, the snap-fit ​​groove snaps into the third rotating shaft.

[0015] On the other hand, this application provides a vehicle including a body, an entertainment device, and a folding mechanism of any of the above, wherein the entertainment device is mounted on the roof of the body via the folding mechanism, and the folding mechanism is used to fold or unfold the entertainment device relative to the roof.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0020] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings.

[0024] 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.

[0025] In existing technologies, automotive ceiling-mounted screens are small and lightweight, with relatively simple folding mechanisms; a single rotating mechanism suffices to meet usage requirements. However, with the development of smart cockpits, interior designers demand a completely new ceiling-mounted screen effect, for example, a screen no smaller than 22 inches, a thinner and narrower mounting beam, and folding functionality. The folding mechanisms in these technologies, which drive the entertainment equipment, have complex structures and occupy a large amount of space in the height direction of the roof when folded.

[0026] Reference Figure 1 and Figure 2 This application provides a folding mechanism for mounting an entertainment device 2 on a vehicle roof 3. The folding mechanism includes a linkage assembly 11 and an adjustment assembly 13. The linkage assembly 11 is used to movably connect the entertainment device 2 to the vehicle roof 3. The linkage assembly 11 includes a first state in which the entertainment device 2 is folded relative to the vehicle roof 3, and a second state in which the entertainment device 2 is unfolded relative to the vehicle roof 3. The adjustment assembly 13 is disposed on the vehicle roof 3. Along a first direction X, both ends of the adjustment assembly 13 are respectively connected to the linkage assembly 11. The adjustment assembly 13 can be extended or shortened along the first direction X to drive the linkage assembly 11 to switch between the first state and the second state. The first direction X is parallel to the extension plane of the vehicle roof 3.

[0027] In this embodiment of the application, the linkage assembly 11 includes a first state in which the entertainment device 2 is folded relative to the roof 3. The first state can also be understood as the folded state of the folding assembly 1. In the first state, the entertainment device 2 is folded up and pressed against the roof 3 by the linkage assembly 11. The entertainment device 2 and the roof 3 are in a relatively parallel positional relationship. At this time, the entertainment device 2 is in a hidden or minimal space-occupying state.

[0028] In this embodiment of the application, 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 2 and the roof 3, and the entertainment device 2 is unfolded relative to the roof 3 and is located within the user's field of vision.

[0029] In this embodiment, the entertainment device 2 can be a display device, an audio entertainment device, or an interactive device, etc., and this application does not limit it in this regard. For example, the entertainment device 2 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.

[0030] In this embodiment, the adjustment component 13 is disposed on the roof 3. The adjustment component 13 can be extended or shortened along the first direction X. The first direction X is parallel to the extension plane of the roof 3. The first direction X can be along the length direction of the vehicle or along the width direction of the vehicle, so as to adjust the orientation of the entertainment device 2 in the unfolded state.

[0031] In this embodiment of the application, the adjustment mechanism can be extended or shortened along the first direction X. When the adjustment mechanism is extended along the first direction X, the linkage assembly 11 can be switched to the first state; when the adjustment mechanism is shortened along the first direction X, the linkage assembly 11 can be switched to the second state.

[0032] In another embodiment, when the adjusting mechanism extends along the first direction X, the link assembly 11 can be switched to the second state; when the adjusting mechanism shortens along the first direction X, the link assembly 11 can be switched to the first state.

[0033] In this embodiment of the folding mechanism, since both ends of the linkage assembly 11 are respectively connected to the adjustment assembly 13, when the adjustment assembly 13 extends along the first direction X, the adjustment assembly 13 pushes both ends of the linkage assembly 11 to move in the first direction X, increasing the distance between the two ends of the linkage assembly 11. When the adjustment assembly 13 shortens along the first direction X, the adjustment assembly 13 pulls both ends of the linkage assembly 11 in the first direction X, shortening the distance between the two ends of the linkage assembly 11. Thus, the linkage assembly 11 can be switched between a first state and a second state, folding or unfolding the entertainment device 2 relative to the roof 3. Therefore, by extending and shortening the adjustment mechanism in the first direction X to switch the linkage assembly 11 between the first and second states, the complex rotational folding motion is transformed into a simple linear motion, simplifying the structure. Since the adjustment mechanism is installed on the roof 3, the two ends of the linkage assembly 11 are respectively connected to the adjustment mechanism, and the adjustment assembly 13 is set on the roof 3 along the first direction X. The first direction X is parallel to the extension plane of the roof 3. Therefore, when the adjustment mechanism moves along the first direction X, it is equivalent to a part of the structure of the folding mechanism and the space of movement sharing the space in the height direction of the vehicle with the roof 3. In this way, the space occupied in the height direction of the vehicle can be reduced after the folding mechanism is folded.

[0034] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In some possible embodiments of this application, the adjustment assembly 13 includes a first link 132 and a second link 133. The first link 132 and the second link 133 are rotatably connected by a first rotating shaft 134, the axis of which is perpendicular to the roof 3. The end of the first link 132 away from the second link 133 is rotatably connected to the first end 111 of the link assembly 11, and the end of the second link 133 away from the first link 132 is driveably connected to the second end 112 of the link assembly 11.

[0035] In this embodiment, the axial direction of the first rotating shaft 134 is perpendicular to the roof 3, that is, the circumferential direction of the first rotating shaft 134 is perpendicular to the first direction X. The first connecting rod 132 and the second connecting rod 133 are rotatably connected through the first rotating shaft 134, that is, the first connecting rod 132 and the second connecting rod 133 can rotate around the first rotating shaft 134. By rotating the first connecting rod 132 and the second connecting rod 133 relative to the first rotating shaft 134, the length of the adjusting component 13 in the first direction X can be changed. The length of the adjusting component 13 in the first direction X is the distance between the end of the first connecting rod 132 away from the second connecting rod 133 and the end of the second connecting rod 133 away from the first connecting rod 132.

[0036] In this embodiment, the first link 132 and the second link 133 can be links extending along a straight line or links extending along an arc. For example, refer to... Figure 1 and Figure 2 The first link 132 and the second link 133 are respectively connected to the two sides of the first rotating shaft 134. The first link 132 and the second link 133 have a Z-shaped structure to avoid other parts or to be more compact when folded.

[0037] In this embodiment of the application, the first end 111 and the second end 112 refer to two basic hinge points or connecting edges on the link assembly 11 that are connected to the roof 3, and the extension directions of the first end 111 and the second end 112 are parallel to the extension direction of the roof 3.

[0038] In this embodiment of the folding mechanism, the end of the first link 132 away from the second link 133 is rotatably connected to the first end 111 of the link assembly 11, and the end of the second link 133 away from the first link 132 is driveably connected to the second end 112 of the link assembly 11. The first link 132 and the second link 133 rotate relative to each other around the first pivot 134, making the included angle between the first link 132 and the second link 133 smaller, forming a "V" shape, thereby pulling the first end 111 and the second end 112 of the link assembly 11 closer to each other; the first link 132 and the second link 133 rotate in opposite directions around the first pivot 134, making the included angle between the first link 132 and the second link 133 larger, forming a "V" shape, thereby pushing the first end 111 and the second end 112 of the link assembly 11 away from each other, thus allowing the link assembly 11 to switch between the first state and the second state.

[0039] Reference Figure 5 , Figure 6 and Figure 7 In some possible embodiments of this application, the first link 132, the second link 133, and the first rotating shaft 134 constitute the adjusting link 131. The adjusting assembly 13 also includes a driving member 135. There are two adjusting links 131. The driving member 135 is disposed between the two adjusting links 131 and is connected to the first rotating shaft 134 of the two adjusting links 131 respectively. The driving member 135 can extend or shorten along the second direction Y to drive the first link 132 and the second link 133 of the two adjusting links 131 to rotate around the corresponding first rotating shaft 134. The second direction Y is parallel to the extension plane of the roof 3 and perpendicular to the first direction X.

[0040] In this embodiment, two adjusting rods 131 are symmetrically arranged at both ends of the driving member 135, referring to... Figure 5 and Figure 6 The first rotating shaft 134 of the two adjusting links 131 moves away from or towards the second direction Y under the drive of the driving member 135.

[0041] In this embodiment, when the drive member 135 is extended, the drive member 135 will push the two first rotating shafts 134 away from each other, the first connecting rod 132 and the second connecting rod 133 will rotate around the first rotating shaft 134, the included angle between the first connecting rod 132 and the second connecting rod 133 will decrease, and the two ends of the connecting component will move closer to each other.

[0042] In this embodiment, the second direction Y is parallel to the extended plane of the roof 3 and perpendicular to the first direction X. For example, the first direction X is the length direction of the vehicle, the first pivot 134 is the height direction of the vehicle, and the second direction Y is the width direction of the vehicle.

[0043] In this embodiment of the application, the driving component 135 can be a double-headed electric push rod, a two-way lead screw, or a telescopic sleeve, etc. For example, the driving component 135 is a double-headed electric push rod. The push rods at both ends of the driving component 135 are respectively connected to two first rotating shafts 134. After the driving component 135 is energized, the push rods at both ends can extend and retract synchronously to drive the first rotating shafts 134 of the two adjusting links 131 to move away from or towards the second direction Y.

[0044] In this embodiment of the folding mechanism, since the driving member 135 is disposed between the two adjusting links 131 and is connected to the first rotating shaft 134 of the two adjusting links 131 respectively, the movement of the two adjusting links 131 can be synchronously controlled by one driving member 135. The movement of the two adjusting links 131 drives the two ends of the link assembly 11 to move in the first direction X, so that the two sides of the link assembly 11 are subjected to balanced force and the movement is synchronous, reducing the jamming or deflection of the entertainment device 2 during the lifting process. Since the driving member 135 can be extended or shortened along the second direction Y, which is perpendicular to the first direction X and parallel to the extension plane of the roof 3, the linear movement of the driving member 135 itself can be efficiently converted into the symmetrical rotational movement of the two adjusting links 131, optimizing the force transmission path and improving mechanical efficiency.

[0045] Meanwhile, since the drive component 135 is located between the two adjusting links 131, and the adjusting links 131 are located on the roof 3, the drive component 135 is located on the roof 3. The drive component 135 and the adjusting links occupy the same height space in the height direction of the vehicle, thereby reducing the space occupied in the height direction of the vehicle.

[0046] In some possible embodiments of this application, the adjusting link 131 includes a plurality of adjusting links 131, which are disposed between the first end 111 and the second end 112 of the link assembly 11. The plurality of adjusting links 131 are arranged along a second direction Y, which is consistent with the extension direction of the first end 111 and / or the second end 112.

[0047] In this embodiment of the application, a plurality of adjusting links 131 are disposed between the first end 111 and the second end 112, and together drive the first end 111 and the second end 112 of the connecting assembly to move in the first direction X.

[0048] In this embodiment, the number of adjusting links 131 can be adjusted according to the motion requirements of the adjusting component 13. Multiple adjusting links 131 can be evenly spaced along the second direction Y. Multiple adjusting links 131 can also be arranged symmetrically about the center of the driving component 135 along the second direction Y.

[0049] In this embodiment, the second direction Y can be consistent with the extension direction of the first end 111; the second end 112 can also be consistent with the extension direction of the second end 112; the second direction Y, the extension directions of the first end 111 and the second end 112 can be consistent. For example, the first end 111 and the second end 112 extend along the width direction of the vehicle, and a plurality of adjusting links 131 are arranged along the width direction of the vehicle.

[0050] In the folding mechanism of this application embodiment, since multiple adjusting links 131 are arranged along the second direction Y between the first end 111 and the second end 112 of the linkage assembly 11, the load that is relatively close to or perpendicular to the first end 111 and the second end 112 of the driving linkage assembly 11 can be distributed to multiple support points, thereby improving the load-bearing capacity of the adjusting assembly 13 and reducing the possibility of structural deformation or failure due to single-point force. Since the second direction Y is consistent with the extension direction of the first end 111 and / or the second end 112, the force applied by the multiple adjusting links 131 to the first end 111 and the second end 112 of the linkage assembly 11 is perpendicular to the extension direction of the first end 111 and / or the second end 112. This enables the movement of the multiple adjusting links 131 to be coordinated and act together on the mutual separation and proximity of the first end 111 and the second end 112, reducing internal interference and additional wear caused by mismatch in movement directions.

[0051] Reference Figure 1 , Figure 3 , Figure 3 and Figure 4 In some possible embodiments of this application, the linkage assembly 11 includes a third link 113 and a fourth link 114, the fourth link 114 being used to mount the entertainment device 2; the third link 113 and the fourth link 114 are rotatably connected via a second pivot 115, the end of the third link 113 away from the fourth link 114 is rotatably connected to the second link 133 via a third pivot 116, and the end of the fourth link 114 away from the third link 113 is rotatably connected to the first link 132 via a fourth pivot 117, the second pivot 115, the third pivot 116, and the fourth pivot 117 extending along a second direction Y; the adjustment assembly 13 is used to adjust the third pivot 116 and the fourth pivot 117 to be relatively closer or farther apart in the first direction X.

[0052] In this embodiment, the third link 113 and the fourth link 114 can extend along the second direction Y to form a plate-like structure, which can increase the area of ​​the third link 113 and the fourth link 114 connected to the second rotating shaft 115, the third rotating shaft 116 and the fourth rotating shaft 117, thereby improving the stability of the relative movement between the link assembly 11 and the adjustment assembly 13.

[0053] In another embodiment, there may be multiple third links 113 and fourth links 114. The link assembly 11 also includes a first support plate and a second support plate. The third link 113 is disposed on the first support plate, and the fourth link 114 is disposed on the second support plate. Both of them extend along the second direction Y. The entertainment device 2 is disposed on the side of the second support plate opposite to the fourth link 114.

[0054] In this embodiment, the second rotating shaft 115 can be integrally formed with the third connecting rod 113, and the fourth connecting rod 114 is rotatably mounted on the second rotating shaft 115; in another embodiment, the second rotating shaft 115 can be a shaft passing through the third connecting rod 113 and the fourth connecting rod 114, so that the third connecting rod 113 and the fourth connecting rod 114 can rotate relative to each other.

[0055] In this embodiment of the application, the third link 113 and the second link 133 are connected by a third rotating shaft 116. The third rotating shaft 116 can be integrally formed with the third link 113, or the third rotating shaft 116 can be a shaft that passes through the third link 113 and the second link 133.

[0056] In this embodiment, the third rotating shaft 116 can be slidably connected to the roof 3. The roof 3 is provided with a slide rail. The two ends of the third rotating shaft 116 are slidably disposed in the slide rail of the roof 3. Under the drive of the adjusting component 13, the third rotating shaft 116 can slide along the slide rail so as to change the extension or shortening of the adjusting component 13 in the first direction X.

[0057] In this embodiment of the application, a connecting shaft 12 may be sleeved on the third rotating shaft 116 and the fourth rotating shaft 117. The second connecting rod 133 is hinged to the third rotating shaft 116 through the connecting shaft 12 on the third rotating shaft 116; the first connecting rod 132 is hinged to the fourth rotating shaft 117 through the connecting shaft 12 on the fourth rotating shaft 117.

[0058] In this embodiment, the drive member 135 of the adjustment component 13 drives the two first rotating shafts 134 of the two adjustment links 131 to move closer to each other. The first link 132 and the second link 133 rotate around the first rotating shaft 134, and the included angle between the first link 132 and the second link 133 increases. The adjustment link 131 extends in the first direction X, pushing the third rotating shaft 116 to slide on the slide rail on the roof 3. The distance between the third rotating shaft 116 and the fourth rotating shaft 117 increases. The third link 113 and the fourth link 114 rotate around the second rotating shaft 115, and the included angle increases. Thus, the third link 113 and the fourth link 114 gradually approach the roof 3, and the folding mechanism folds relative to the roof 3.

[0059] In the folding mechanism of this application embodiment, the third link 113 and the fourth link 114 are rotatably connected via the second pivot 115. At the same time, the ends of the third link 113 and the fourth link 114 away from the second pivot 115 are respectively connected to the adjustment component 13. Thus, a three-bar structure is formed between the third link 113, the adjustment component 13, and the fourth link 114. When the link assembly 11 is unfolded relative to the roof 3, a triangular support structure can be formed between the third link 113, the adjustment component 13, and the fourth link 114, thereby improving the stability of the unfolded link assembly 11.

[0060] Reference Figure 6 , Figure 7 , Figure 8 and Figure 9 In some possible embodiments of this application, the folding mechanism further includes a locking component 14, which includes a first locking member 141 and a second locking member 142. The first locking member 141 is disposed on the adjusting component 13 or the linkage assembly 11, and the second locking member 142 is disposed on the fourth linkage 114 or the entertainment device 2. When the adjusting component 13 drives the linkage assembly 11 to switch to the first state or the second state, the first locking member 141 and the second locking member 142 cooperate to unlock or lock.

[0061] In this embodiment, the first locking member 141 is disposed on the adjustment component 13 or the linkage component 11. The first locking component 14 moves with the movement of the adjustment component 13 and the linkage component 11. The second locking component 14 is disposed on the fourth linkage 114 or the entertainment component. When the linkage component 11 is switched to the second state, the first locking member 141 and the second locking member 142 move to a relative position, so that the first locking member 141 and the second locking member 142 can be unlocked or locked.

[0062] For example, the first locking element 141 may be a locking pin with a spring, which is mounted on the adjusting assembly 13 (such as the first link 132); the second locking element 142 is one or more positioning holes, which may be provided in the fourth link 114. When the mechanism moves to the unfolded or folded position, the locking pin automatically springs into the positioning hole under the action of the spring force to lock, and needs to be manually pulled out to unlock.

[0063] The folding mechanism of this application embodiment includes a first locking member 141 disposed on the adjustment component 13 or the linkage component 11, and a second locking member 142 disposed on the fourth linkage 114 or the entertainment device 2. When the adjustment component 13 drives the linkage component 11 to switch to the first state (folded) or the second state (unfolded), the first locking member 141 and the second locking member 142 cooperate to unlock or lock. Therefore, when the linkage component 11 rotates to the first state or the second state, it can trigger locking or unlocking, so that the entertainment device 2 is locked in the folded state, which improves the stability in the folded state.

[0064] Reference Figure 8 , Figure 9 and Figure 10 In some possible embodiments of this application, the first locking member 141 includes a locking portion 1411, a first connecting portion 1412, and a second connecting portion 1413. The locking portion 1411 and the first connecting portion 1412 are respectively disposed at both ends of the first locking member 141. The first connecting portion 1412 is rotatably connected to the third rotating shaft 116 via a fifth rotating shaft 143. The second connecting portion 1413 is disposed between the locking portion 1411 and the first connecting portion 1412. The second connecting portion 1413 is rotatably connected to the second connecting rod 133 via a sixth rotating shaft 144. The fifth rotating shaft 143 and the sixth rotating shaft 144 are axially aligned with the first rotating shaft 134. When the adjusting assembly 13 extends or shortens along the first direction X, the first locking member 141 rotates around the fifth rotating shaft 143 to drive the locking portion 1411 closer to or away from the second locking member 142.

[0065] In this embodiment, the locking part 1411 is used to cooperate with the second locking member 142 to lock or unlock the locking assembly 14. The locking part 1411 can be a hook, pin, or claw, etc. The first connecting part 1412 is located on the first locking member 141 at the end away from the locking part 1411. The first connecting part 1412 is connected to the third rotating shaft 116 (i.e., the hinge point between the third connecting rod 113 and the second connecting rod 133) through the fifth rotating shaft 143, that is, the first locking member 141 can rotate relative to the third rotating shaft 116. The second connecting part 1413 is located between the locking part 1411 and the first connecting part 1412, and is connected to the second connecting rod 133 (adjusting assembly 13) through the sixth rotating shaft 144. The second connecting part 1413 can rotate relative to the second connecting rod 133 (adjusting assembly 13) around the sixth rotating shaft 144.

[0066] In this embodiment of the application, the locking part 1411 may be a hook-shaped structure, and the second locking member 142 is a snap-fit ​​structure adapted to the locking part 1411. The locking part 1411 and the second locking member 142 snap-fit ​​to lock the first locking member 141 and the second locking member 142.

[0067] In another embodiment, the second locking member 142 can be a cylindrical locking pin, fixed to the fourth link 114. When the link assembly 11 moves to the second state, the adjusting component 13 pushes the first locking member 141 to rotate, so that the locking part 1411 rotates to the second locking member 142 and locks it in place. When unlocking is required, the link assembly 11 switches to the first state, and the adjusting component 13 pulls the first locking member 141 to rotate in the opposite direction, so that the locking part 1411 disengages from the locking pin.

[0068] In the folding mechanism of this application embodiment, the first locking part 1411 can move relative to the second locking part 1411 under the drive of the adjusting component 13. When the adjusting component 13 shortens (drives the mechanism to fold) or extends (drives the mechanism to unfold), the second connecting rod 133 will move. The movement of the second connecting rod 133 is transmitted to the first locking member 141 through the sixth rotating shaft 144, pushing or pulling the first locking member 141. Since the first connecting part 1412 of the first locking member 141 is rotatably connected to the third rotating shaft 116 through the fifth rotating shaft 143, the pushing or pulling force of the second connecting rod 133 will cause the first locking member 141 to rotate around the fifth rotating shaft 143, driving the locking part 1411 to rotate around the sixth rotating shaft 144 as the center, thereby moving closer to or away from the second locking member 142, and cooperating with the second locking member 142 to achieve automatic locking and unlocking.

[0069] Reference Figure 10In some possible embodiments of this application, the locking assembly 14 further includes an elastic member 145. One end of the elastic member 145 is disposed on the side of the first locking member 141 near the first connecting portion 1412, and the other end of the elastic member 145 is disposed on the side of the second connecting rod 133 near the second connecting portion 1413. When the first locking member 141 rotates around the fifth rotating axis 143, the first locking member 141 overcomes the elastic force of the elastic member 145.

[0070] In this embodiment, the elastic element 145 can be a torsion spring. The torsion spring is located at the sixth rotating shaft 144 or the fifth rotating shaft 143. One end of the torsion spring is connected to the first connecting part 1412, and the other end of the torsion spring is connected to the second connecting rod 133. When the first locking element 141 rotates around the fifth rotating shaft 143, the two torsion arms of the torsion spring rotate relative to each other, and the first locking element 141 overcomes the elastic force of the torsion spring.

[0071] In another embodiment, the elastic element 145 may be a compression spring or a tension spring, and the first locking element 141 and the second locking element 142 are provided with mounting posts for mounting the spring. The elastic element 145 is connected between the mounting posts of the first locking element 141 and the second link 133, and the extension and contraction of the spring provides a pulling force or a pushing force to rotate the first locking element 141.

[0072] In the folding mechanism of this application embodiment, since one end of the elastic member 145 is disposed on the side of the first locking member 141 near the first connecting part 1412, and the other end of the elastic member 145 is disposed on the side of the second connecting rod 133 near the second connecting part 1413, the preload of the elastic member 145 can provide a continuous and stable torque to the first locking member 141, so that the locking part 1411 has a tendency to move closer to the second locking member 142, providing power for the automatic locking of the locking member. Since the first locking member 1411 needs to overcome the elastic force of the elastic member 145 when the locking part 1411 rotates around the sixth rotating axis 144 to achieve locking or unlocking, the locking or unlocking action can be achieved by the force applied by the adjusting component 13, thereby reducing the situation of accidental unlocking caused by vibration or accidental contact.

[0073] Reference Figure 10 In some possible embodiments of this application, the first locking member 141 further includes a snap-fit ​​portion 146, which includes a snap-fit ​​groove that matches the third rotating shaft 116. When the first locking member 141 rotates about the fifth rotating shaft 143 to drive the locking portion 1411 closer to or away from the second locking member 142, the snap-fit ​​groove snaps into the third rotating shaft 116.

[0074] In this embodiment, the engaging part 146 is provided with an engaging groove, the shape of which matches the third rotating shaft 116 (the shaft connecting the third connecting rod 113 and the second connecting rod 133). When the first locking member 141 rotates to the locking position, the engaging groove can wrap around and lock the third rotating shaft 116. During the process of the connecting rod assembly 11 switching from the first state to the second state, the first locking member 141 rotates around the fifth rotating shaft 143, and the engaging groove is separated from or has a gap with the third rotating shaft 116. When the first locking member 141 rotates to the position where the locking part 1411 and the second locking member 142 complete the engagement (i.e., locking), the engaging groove also happens to engage with the third rotating shaft 116.

[0075] In this embodiment, the cross-section of the snap-fit ​​groove can be V-shaped, rectangular, or arc-shaped, etc. The cross-section of the snap-fit ​​groove can be adapted to the shape of the third rotating shaft 116.

[0076] In another embodiment, a connecting shaft 12 is provided on the third rotating shaft 116, and a fifth rotating shaft 143 is provided on the third rotating shaft 116. When the first locking member 141 rotates to the position where the locking part 1411 and the second locking member 142 are engaged (i.e. locked), the snap-fit ​​groove engages with the connecting shaft 12, and the shape of the snap-fit ​​groove is adapted to the shape of the connecting shaft 12.

[0077] In the folding mechanism of this application embodiment, the locking part 146 engages with the third rotating shaft 116. This is equivalent to the locking part 146 and the third rotating shaft 116 engaging when the locking part 1411 is locked with the second locking member 142, thereby forming a double lock, improving the stability of the lock, enhancing the rigidity and impact resistance of the folding mechanism in the locked state, and reducing the occurrence of slight relative displacement or shaking between components due to heavy load or vibration.
