Description

Technical Field

[0001] This utility model belongs to the field of lock technology and relates to a latching mechanism, a moving component, a table assembly, and a vehicle. Background Technology

[0002] In the prior art, the latch can only engage and lock one striker at a time. The latch is a single-point lock and cannot lock two strikers at the same time, resulting in insufficient locking stability. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a latching mechanism, a moving component, a table assembly, and a vehicle to achieve simultaneous locking of two striking pins.

[0004] To solve the above-mentioned technical problems, on the one hand, the present invention provides a latching mechanism, including a latching housing, a first pawl, a second pawl, a release member, a first reset member, a second reset member and a third reset member, wherein the first pawl, the second pawl and the release member are respectively rotatably connected to the latching housing, and the release member is located between the first pawl and the second pawl;

[0005] The first reset member is used to cause the first pawl to have a tendency to rotate in a first rotation direction; the second reset member is used to cause the second pawl to have a tendency to rotate in the first rotation direction; the third reset member is used to cause the release member to have a tendency to rotate in a second rotation direction; the first rotation direction is opposite to the second rotation direction;

[0006] The latching mechanism has a locked state and an unlocked state; in the unlocked state, the release member disengages from the first pawl and the second pawl respectively; in the locked state, one end of the release member abuts against the first pawl, and the other end of the release member abuts against the second pawl.

[0007] In this embodiment of the latching mechanism, in the unlocked state, the release member disengages from both the first and second pawls; in the locked state, one end of the release member abuts against the first pawl, and the other end abuts against the second pawl. The first pawl can rotate in a second rotation direction and lock the first firing pin upon impact, while the second pawl can rotate in a second rotation direction and lock the second firing pin upon impact. Thus, by having the release member abut against both the first and second pawls, the latching mechanism can simultaneously lock both firing pins. When the first and second firing pins are mounted on the same component, the release member simultaneously locks two parts of one component, enhancing locking rigidity and improving locking stability. When the first and second firing pins are mounted on different components, a single release member can lock both components, resulting in a simpler structure. Furthermore, in the locked state, by driving the release member to rotate along the first rotation direction, the locking force between the release member and the first and second pawls is overcome, simultaneously unlocking the first and second pawls, thus allowing the latching mechanism to return to the unlocked state. Therefore, the latching mechanism of this invention uses the same release member for both unlocking and locking, effectively ensuring the synchronous unlocking and locking of the two striking pins.

[0038] The movable component of this utility model embodiment has all the advantages of the latching mechanism described above.

[0039] Different components are mounted on the moving parts to achieve different functions.

[0040] For example, the movable component can be used to install a small table. In this case, the first direction is the height direction of the vehicle.

Simultaneously, the release mechanism of the front latching mechanism locks the first and second pawls, and the latching mechanism enters the locked state, locking the seat in the forward position. When the movable component moves backward into position, the first and second striking pins of the movable component are locked by the first and second pawls of the rear latching mechanism, respectively. Simultaneously, the release mechanism of the rear latching mechanism locks the first and second pawls, and the latching mechanism enters the locked state, locking the seat in the rear position. This allows for two position adjustments of the seat.

[0042] For example, the movable component can be used to mount the center console. The center console moves together with the movable component. When the movable component is in place, its first and second striking pins are locked by the first and second pawls of the latching mechanism, respectively. The latching mechanism then enters the locked state, thus locking the center console in a preset position.

[0043] On the other hand, this utility model embodiment also provides a tabletop assembly, which includes a tabletop body and the aforementioned movable component, wherein the tabletop body is connected to the movable component.

[0058] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0059] See Figures 1 to 6This utility model provides a latching mechanism 10, including a latch housing 1, a first pawl 2, a second pawl 3, a release member 4, a first reset member 5, a second reset member 6, and a third reset member 7. The first pawl 2, the second pawl 3, and the release member 4 are rotatably connected to the latch housing 1, and the release member 4 is located between the first pawl 2 and the second pawl 3. The first reset member 5 is used to give the first pawl 2 a tendency to rotate in a first rotation direction; the second reset member 6 is used to give the second pawl 3 a tendency to rotate in the first rotation direction; the third reset member 7 is used to give the release member 4 a tendency to rotate in a second rotation direction. The first rotation direction and the second rotation direction are opposite; that is, one of the first rotation direction and the second rotation direction is clockwise, and the other is counterclockwise. Figure 5 In the embodiment shown, the first rotation direction is clockwise and the second rotation direction is counterclockwise.

[0060] The latching mechanism 10 has a locked state and an unlocked state; in the unlocked state (see...) Figure 4 and Figure 5 Release element 4 disengages from the first pawl 2 and the second pawl 3 respectively; in the locked state (see...) Figure 2 and Figure 3 One end of the release member 4 abuts against the first pawl 2, and the other end of the release member 4 abuts against the second pawl 3.

[0061] Specifically, the first pawl 2 can rotate in the second rotation direction and lock the first firing pin 201 under the impact of the first firing pin 201, the second pawl 3 can rotate in the second rotation direction and lock the second firing pin 202 under the impact of the second firing pin 202, and the third reset member 7 drives the release member 4 to rotate in the first rotation direction to lock the first pawl 2 and the second pawl 3 at the same time.

[0062] In the locked state (see) Figure 2 and Figure 3 By rotating the release element 4 in the first direction, the latch mechanism 10 can be returned to the unlocked state. The release element 4 can be manually operated or driven by a drive component such as a motor.

[0063] The release element 4 is provided with an operating hole 43. A person can reach into the operating hole 43 to rotate the release element 4, or a special tool can be inserted into the operating hole 43 to drive the release element 4 to rotate.

[0064] The latching mechanism 10 of this embodiment can simultaneously lock two striking pins. When the first striking pin 201 and the second striking pin 202 are disposed on the same component, the release member 4 simultaneously locks two parts of one component, which can enhance the locking rigidity and improve the locking stability. When the first striking pin 201 and the second striking pin 202 are disposed on two different components, two components can be locked by one release member 4, resulting in a simpler structure. Furthermore, in the locked state, by driving the release member 4 to rotate in the first rotation direction, the locking force between the release member 4 and the first pawl 2 and the second pawl 3 is overcome, and the first pawl and the second pawl are unlocked simultaneously, allowing the latching mechanism 10 to return to the unlocked state. Therefore, the latching mechanism of this invention, using the same release member 4 for unlocking and locking, effectively ensures the synchronous unlocking and locking of the two striking pins.

[0065] In one embodiment, see Figure 3 The contact points between the release member 4 and the first pawl 2, and between the release member 4 and the second pawl 3, are located on both sides of the rotation axis of the release member 4 in the horizontal direction, and on both sides of the rotation axis of the release member 4 in the vertical direction.

[0066] According to the latching mechanism 10 provided in this embodiment of the present invention, by setting the contact points of the release member 4 with the first pawl 2 and the release member 4 with the second pawl 3 in the horizontal direction on both sides of the rotation axis of the release member 4; and setting the contact points of the release member 4 with the first pawl 2 and the release member 4 with the second pawl 3 in the vertical direction on both sides of the rotation axis of the release member 4, it is possible to simultaneously unlock or lock two pawls with one release member 4, thus simplifying the arrangement structure of the latching mechanism 10 with the synchronous unlocking and locking functions of two firing pins.

[0067] In one embodiment, see Figure 3 The perpendicular line from the contact point between the release element 4 and the first pawl 2 to the rotation axis of the release element 4 is the first connecting line L1. Figure 3 The dashed line in the middle); the perpendicular line from the contact point between the release member 4 and the second pawl 3 to the rotation axis of the release member 4 is the second connecting line L2 ( Figure 3 (The solid line in the middle); the first line L1 and the second line L2 are collinear.

[0068] According to the latching mechanism 10 provided in this embodiment of the present utility model, by setting the first connecting line L1 and the second connecting line L2 to be collinear, that is, the contact point between the release member 4 and the first pawl 2 and the contact point between the release member 4 and the second pawl 3 are located at both ends of the diameter of the rotation arc with the rotation axis of the release member 4 as the axis, the force on the contact point between the release member 4 and the two pawls can be kept balanced, thereby improving the locking stability of the latching mechanism 10 and ensuring that the first pawl 2 and the second pawl 3 can lock or unlock the firing pin at the same time.

[0069] In one embodiment, see Figures 2 to 5 The first pawl 2 can rotate in the second rotation direction and lock the first firing pin 201 under the impact of the first firing pin 201; the second pawl 3 can rotate in the second rotation direction and lock the second firing pin 202 under the impact of the second firing pin 202; the release member 4 can rotate in the first rotation direction under the drive of the first pawl 2 and the second pawl 3 to avoid the rotation of the first pawl 2 and the second pawl 3, and then rotate in the first rotation direction under the drive of the third reset member 7 to lock the first pawl 2 and the second pawl 3 at the same time, so that the latching mechanism 10 enters the locked state.

[0070] Specifically, the first pawl 2 can rotate in the second rotation direction under the impact of the first firing pin 201. The first pawl 2 pushes the release member 4 to rotate, so that the release member 4 limits the rotation of the first pawl 2 in the first rotation direction, thereby locking the first firing pin 201. Since the third reset member 7 has the tendency to make the release member 4 rotate in the second rotation direction, during the process of the first pawl 2 pushing the release member 4 to rotate, the release member 4 is first pushed by the first pawl 2 to rotate in the first rotation direction to avoid the first pawl 2 being driven by the first firing pin 201 to rotate in the second rotation direction; when the release member 4 rotates to a position where it is no longer pushed by the first pawl 2, the third reset member 7 drives the release member 4 to rotate in the second rotation direction, so that the release member 4 rotates to a position that abuts against the first pawl 2. At this time, the first pawl 2 locks the first firing pin 201 and the release member 4 locks the first pawl 2.

[0071] The second pawl 3 can rotate in the second rotation direction under the impact of the second firing pin 202. The second pawl 3 pushes the release member 4 to rotate, so that the release member 4 limits the rotation of the second pawl 3 in the first rotation direction, thereby locking the second firing pin 202 and enabling the latching mechanism 10 to enter the locked state. Since the third reset member 7 has the tendency to make the release member 4 rotate in the second rotation direction, during the process of the second pawl 3 pushing the release member 4 to rotate, the release member 4 is first pushed by the second pawl 3 to rotate in the first rotation direction to avoid the second pawl 3 being driven by the second firing pin 202 to rotate in the second rotation direction; when the release member 4 rotates to a position where it is no longer pushed by the second pawl 3, the third reset member 7 drives the release member 4 to rotate in the second rotation direction, so that the release member 4 rotates to a position that abuts against the second pawl 3. At this time, the second pawl 3 locks the second firing pin 202 and the release member 4 locks the second pawl 3.

[0072] According to the latching mechanism 10 provided in this embodiment of the present invention, the first pawl 2 and the release member 4 are linked by the first striking pin 201, and the second striking pin 202 is linked by the second pawl 3 and the release member 4. The first striking pin 201 and the second striking pin 202 can be locked simultaneously by changing the relative positions of the first pawl 2 and the release member 4 and the second pawl 3 and the release member 4. The structure is simple and the locking is fast.

[0073] Furthermore, the release member 4 can rotate in the first rotation direction under the drive of the drive member to simultaneously unlock the first pawl 2 and the second pawl 3. The first pawl 2 can rotate in the first rotation direction under the drive of the first reset member 5 to release the first firing pin 201. The second pawl 3 can rotate in the first rotation direction under the drive of the second reset member 6 to release the second firing pin 202, thereby causing the latching mechanism 10 to enter the unlocked state.

[0074] Specifically, the driving member drives the release member 4 to rotate in the first rotation direction, and the release member 4 pushes the first pawl 2 to rotate, so that the release member 4 releases the rotational limitation of the first pawl 2 in the first rotation direction, thereby releasing the first pawl 2 from the first firing pin 201. After the release member 4 releases the rotational limitation of the first pawl 2 in the first rotation direction, since the first reset member 5 has a tendency to rotate the first pawl 2 in the first rotation direction, the first reset member 5 drives the first pawl 2 to rotate in the first rotation direction, thereby releasing the first firing pin 201. When the driving member no longer applies force to the release member 4, since the third reset member 7 has a tendency to rotate the release member 4 in the second rotation direction, the third reset member 7 will also drive the release member 4 to return to its original position.

[0075] The release member 4 pushes the second pawl 3 to rotate, thereby releasing the rotational limitation of the second pawl 3 in the first rotational direction. This allows the second pawl 3 to release the second firing pin 202, enabling the latching mechanism 10 to enter the unlocked state. After the release member 4 releases the rotational limitation of the second pawl 3 in the first rotational direction, the second reset member 6 has a tendency to rotate the second pawl 3 in the first rotational direction. The second reset member 6 drives the second pawl 3 to rotate in the first rotational direction, thereby releasing the second firing pin 202.

[0076] According to the latching mechanism 10 provided in this embodiment of the present invention, the linkage between the release member 4 and the first pawl 2 and the second pawl 3 is driven by the driving member. Simultaneous unlocking of the first striking pin 201 and the second striking pin 202 can be achieved by changing the relative positions of the first pawl 2 and the release member 4, and by changing the relative positions of the second pawl 3 and the release member 4. The structure is simple and the locking is fast. In one embodiment, see... Figure 3 and Figure 5The release member 4 has a first locking surface 41 and a second locking surface 42. The first pawl 2 has a first contact surface 21 and a first firing pin engagement groove 22. The second pawl 3 has a second contact surface 31 and a second firing pin engagement groove 32. In the unlocked state, the first locking surface 41 is disengaged from the first contact surface 21, and the second locking surface 42 is disengaged from the second contact surface 31. In the locked state, the first locking surface 41 abuts against the first contact surface 21, and the first firing pin 201 is engaged in the space formed by the first firing pin engagement groove 22 and the release member 4. The second locking surface 42 abuts against the second contact surface 31, and the second firing pin 202 is engaged in the space formed by the second firing pin engagement groove 32 and the latch housing 1.

[0077] Specifically, the first pawl 2 can rotate in the second rotation direction under the impact of the first firing pin 201, causing the first firing pin 201 to engage in the first firing pin engagement groove 22. The second pawl 3 can rotate in the second rotation direction under the impact of the second firing pin 202, causing the second firing pin 202 to engage in the second firing pin engagement groove 32. This causes the first locking surface 41 to abut against the first contact surface 21 and the second locking surface 42 to abut against the second contact surface 31. Since the first pawl 2 and the first pawl 3 rotate in the same direction, and the rotation direction of the release member 4 is opposite to that of the first pawl 2, the first pawl 2, the second pawl 3, and the release member 4 remain relatively stationary. That is, the release member 4 simultaneously locks the first pawl 2 and the second pawl 3.

[0078] According to the latching mechanism 10 provided in this embodiment of the present invention, the latching mechanism 10 can be unlocked simply and quickly by disengaging the first locking surface 41 from the first contact surface 21 and the second locking surface 42 from the second contact surface 31; by inserting the first firing pin 201 into the first firing pin engaging groove 22 and abutting the first locking surface 41 against the first contact surface 21, the first firing pin 201 can be securely locked in the first firing pin engaging groove 22. Similarly, the second firing pin 202 can also be securely locked in the second firing pin engaging groove 32.

[0079] In one embodiment, in the unlocked state, the first locking surface 41 is located above the first contact surface 21, and the second locking surface 42 is located below the second contact surface 31; in the locked state, the first locking surface 41 is located below the first contact surface 21, and the second locking surface 42 is located above the second contact surface 31.

[0080] According to the latching mechanism 10 provided in this embodiment of the present invention, in the unlocked state, the first locking surface 41 is located above the first contact surface 31, and the second locking surface 42 is located below the second contact surface 31, which enables the release member 4 to not obstruct the movement of the first pawl 2 and the second pawl 3 along the first rotation direction, thereby improving the unlocking speed; in the locked state, the first locking surface 41 is located below the first contact surface 21, and the second locking surface 42 is located above the second contact surface 31, which enables the release member 4 to limit the movement of the first pawl 2 and the second pawl 3 along the first rotation direction, thereby improving the locking stability.

[0081] In one embodiment, see Figures 3 to 5 The first firing pin engagement groove 22 includes a first receiving portion 221 and a first flared portion 222. Along the opening direction of the first firing pin engagement groove 21, the opening area of ​​the first flared portion 222 gradually increases. The first flared portion 222 is adapted to withstand the impact of the first firing pin 201 and guide the first firing pin 201 to slide into the first receiving portion 221. The second firing pin engagement groove 32 includes a second receiving portion 321 and a second flared portion 322. Along the opening direction of the second firing pin engagement groove 32, the opening area of ​​the second flared portion 322 gradually increases. The second flared portion 322 is adapted to withstand the impact of the second firing pin 202 and guide the second firing pin 202 to slide into the second receiving portion 321.

[0082] According to the latching mechanism 10 provided in the embodiment of the present utility model, by gradually increasing the opening area of ​​the first flared portion 222, the first firing pin 201 can be better guided to slide into the first receiving portion 221; by gradually increasing the opening area of ​​the second flared portion 322, the second firing pin 202 can be better guided to slide into the second receiving portion 321.

Thus, the contact area between the second locking surface 42 and the second contact surface 31 is larger, and the stress is minimized.

[0096] According to the latching mechanism 10 provided in the embodiment of this utility model, by setting a first torsion spring, a second torsion spring and a third torsion spring, after the latching mechanism 10 is unlocked, the first pawl 2, the second pawl 3 and the release member 4 can be driven to reset, in preparation for the next locking.

[0097] In other embodiments, one leg of the first torsion spring is fixed to the latch housing 1, and the other leg of the first torsion spring can also abut or connect to any position of the first pawl 2, provided that a preload is applied to the first torsion spring in the first rotational direction.

[0100] In one embodiment, see Figure 1 The first rotating shaft 81, the second rotating shaft 82, and the third rotating shaft 83 are all rivets. Holes for riveting the first rotating shaft 81, the second rotating shaft 82, and the third rotating shaft 83 are provided on the latch housing 1.

[0101] In other embodiments, the first rotating shaft 81, the second rotating shaft 82, and the third rotating shaft 83 may also be bolts or pins.

[0102] In other embodiments, the first reset member 5, the second reset member 6, and the third reset member 7 may also be cylindrical springs or leaf springs, etc.

[0103] In one embodiment, see Figure 1 , Figure 2 and Figure 4 The latch housing 1 is provided with a first clearance notch 11 for avoiding the first firing pin 201 and a second clearance notch 12 for avoiding the second firing pin 202. The first firing pin 201 enters the first firing pin engagement groove 22 through the first clearance notch 11, and the second firing pin 202 enters the second firing pin engagement groove 32 through the second clearance notch 21.

[0104] According to the latching mechanism 10 provided in the embodiment of this utility model, by providing a first clearance notch 11 and a second clearance notch 21 on the latch housing 1, the first firing pin 201 can enter the first firing pin engagement groove 22 without being obstructed by the latch housing 1, and the second firing pin 202 can enter the second firing pin engagement groove 32 without being obstructed by the latch housing 1. Thus, the first pawl 2 and the second pawl 3 can be integrated into the latch housing 1, and the arrangement is more compact.

[0105] In one embodiment, see Figure 1 The latch housing 1 includes a first plate portion 13 and a second plate portion 14 spaced apart from each other. Both the first plate portion 13 and the second plate portion 14 are provided with a first clearance notch 11 and a second clearance notch 12.

[0107] In one embodiment, see Figure 1 The first pawl 2, the second pawl 3, the release member 4, the first reset member 5, the second reset member 6, and the third reset member 7 are all located between the first plate portion 13 and the second plate portion 14, making the latching mechanism 10 compact.

[0108] In one embodiment, see Figure 6 The latch housing 1 is provided with a first limiting member 91, a second limiting member 92, and a third limiting member 93. The first limiting member 91 is disposed opposite to the first pawl 2, the second limiting member 92 is disposed opposite to the second pawl 3, and the third limiting member is disposed opposite to the release member 4. In the unlocked state, the first limiting member is used to limit the rotation of the first pawl 2 along the first rotation direction, the second limiting member is used to limit the rotation of the second pawl 3 along the first rotation direction, and the third limiting member is used to limit the rotation of the release member 4 along the second rotation direction.

[0109] In one embodiment, a first limiting member 91, a second limiting member 92 and a third limiting member 93 are disposed on the side surface of the first plate portion 13 facing the second plate portion 14.

[0110] In another embodiment, the first limiting member 91, the second limiting member 92 and the third limiting member 93 are disposed on the side surface of the second plate portion 14 facing the first plate portion 13.

[0111] exist Figure 1 In the illustrated embodiment, the first limiting member 91, the second limiting member 92, and the third limiting member 93 are columnar (e.g., cylindrical). However, in other embodiments, the first limiting member 91, the second limiting member 92, and the third limiting member 93b may also be protruding.

[0112] In one embodiment, the first limiting member 91, the second limiting member 92 and the third limiting member 93 are integrally formed with the housing 1.

[0113] In another embodiment, the first limiting member 91, the second limiting member 92 and the third limiting member 93 are respectively formed with the housing 1 and fixedly connected.

[0114] According to the embodiments provided by this utility model, by providing a first limiting member, a second limiting member and a third limiting member on the latch housing 1, it is possible to prevent the latch mechanism 10 from generating abnormal noise during vehicle operation.

[0115] See Figure 7 and Figure 8On the other hand, this utility model embodiment also provides a moving component, including a moving part 20, a guide part 30, a mounting plate 40 and a latching mechanism 10 as described above. The latching housing 1 is mounted on the mounting plate 40, the mounting plate 40 is a stationary part, the moving part 20 is movably connected to the guide part 30 along a first direction, and the moving part 20 is provided with a first striking pin 201 and a second striking pin 202.

[0116] According to the embodiments provided by this utility model, by providing a first striking pin 201 and a second striking pin 202 on the moving part 20 to cooperate with the latching mechanism 10, the locking stiffness of the moving part 20 can be enhanced and the locking stability can be improved.

[0117] The movable component of this utility model embodiment has all the advantages of the latching mechanism 10 described above.

[0118] See Figure 7 The guide component 30 includes two parallel slide rails 301 spaced apart. The movable component 20 is movably connected to the two slide rails 301.

[0119] In other embodiments, the guide component 30 may also include only one slide rail 301, or the guide component 30 may be a lead screw.

[0120] Different components are mounted on the movable part 20 to achieve different functions.

[0121] For example, the movable component 20 can be used to install a small table (table body). In this case, the first direction is the height direction of the vehicle. The small table moves together with the movable component 20. When the movable component 20 rises to a certain height, the first striking pin 201 and the second striking pin 202 of the movable component 20 are locked by the first pawl 2 and the second pawl 3, respectively. The release component 4 simultaneously locks the first pawl 2 and the second pawl 3, and the latching mechanism 10 enters the locked state to lock the small table at a predetermined height.

[0122] For example, the movable component 20 can be used to install a seat. In this case, the first direction is the vehicle's forward / backward direction, and there is one latching mechanism 10 at the front and one at the rear. The seat moves together with the movable component 20. When the movable component 20 moves forward into position, the first striking pin 201 and the second striking pin 202 of the movable component 20 are respectively locked by the first pawl 2 and the second pawl 3 of the front latching mechanism 10. Simultaneously, the release component 4 of the front latching mechanism 10 locks the first pawl 2 and the second pawl 3, and the latching mechanism 10 enters a locked state, locking the seat in the forward position. When the movable component 20 moves backward into position, the first striking pin 201 and the second striking pin 202 of the movable component 20 are respectively locked by the first pawl 2 and the second pawl 3 of the rear latching mechanism 10. Simultaneously, the release component 4 of the rear latching mechanism 10 locks the first pawl 2 and the second pawl 3, and the latching mechanism 10 enters a locked state, locking the seat in the rear position. This allows for two position adjustments of the seat.

[0123] For example, the movable component 20 can be used to install the center console. The center console moves together with the movable component 20. When the movable component 20 is in place, the first striking pin 201 and the second striking pin 202 of the movable component 20 are locked by the first pawl 2 and the second pawl 3 of the latching mechanism 10, respectively. The latching mechanism 10 enters the locked state to lock the center console in a preset position.

[0124] In one embodiment, the movable element 20 can be driven by hand.

[0125] In another embodiment, the movable member 20 can also be driven by a drive mechanism. The drive mechanism can be a linear actuator, such as an electric cylinder, pneumatic cylinder, hydraulic cylinder, or linear motor. The drive mechanism can also be an elastic element (e.g., a spring), with one end connected to the movable member 20 and the other end connected to the mounting plate 40. The elastic element always pulls the movable member 20 upward. The movable member 20 can be locked in the initial position by a locking mechanism. When the locking mechanism releases the movable member 20, after the movable member 20 rises to a certain height, the first striking pin 201 and the second striking pin 202 of the movable member 20 are locked by the first pawl 2 and the second pawl 3, respectively. The release member 4 simultaneously locks the first pawl 2 and the second pawl 3, and the latching mechanism 10 enters the locked state to lock the small table at a predetermined height.

[0126] The locking mechanism described above can be a snap-fit ​​structure.

[0127] The aforementioned locking mechanism can also be a linear locking mechanism. The linear locking mechanism includes a linear drive and a locking rod connected to the output end of the linear drive. The moving part 20 or the table body 50 can be provided with a locking hole or a locking groove. The linear locking mechanism drives the locking rod to enter and exit the locking hole or locking groove to lock or release the moving part 20 or the table body 50.

[0128] On the other hand, see Figure 9This utility model embodiment also provides a tabletop assembly, including a tabletop body 50 and the moving component described in the above embodiment, wherein the tabletop body 50 is connected to the moving component 20.

[0129] Furthermore, this embodiment of the invention also provides a vehicle that includes at least one of the latching mechanism 10, the moving component, and the table assembly described in the above embodiments. Specifically, the vehicle can use the latching mechanism 10 alone, or in combination with a table assembly having the latching mechanism 10. The vehicle of this embodiment of the invention possesses all the advantages of the latching mechanism described above.

[0130] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
