Description

Technical Field

[0001] This invention relates to a locking device, a sleeping basket device, and a carrier. Background Technology

[0002] In existing technologies, two components are typically locked together using the engagement of a bolt and a lock groove. When it is necessary to release the lock, an unlocking component connected to the bolt applies force to the bolt, causing it to disengage from the lock groove. However, in this type of locking structure, when it is necessary to relock the two components, the unlocking component connected to the bolt can interfere with the bolt's movement, thus preventing the bolt from entering the lock groove, affecting locking speed and accuracy, and even causing misalignment between the bolt and the lock groove, leading to locking failure and creating a security hazard. Summary of the Invention

[0003] The purpose of this invention is to provide a new locking device.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: a locking device for locking connection between a first component and a second component, the locking device comprising: A locking element, which is movably disposed on the first component and moves between a locked position and an unlocked position on the first component; A mating part is provided on the second component, and when the locking member is in the locked position, it can engage with the mating part to lock the locking device. A first reset element is used to drive the locking element toward the locking position; An unlocking component is movably disposed on the first component. The unlocking component has at least a first position and a second position on the first component. In the first position, the unlocking component is disengaged from the locking component. In the second position, the unlocking component and the locking component cooperate with each other so that when the unlocking component moves, it can drive the locking component to move from the locked position to the unlocked position. When the first component and the second component move relative to each other, the unlocking component is in the first position.

[0005] In some embodiments, the locking device further includes an operating component movably disposed on the first component. The operating component has a switchable first operating state and a second operating state. In the first operating state, the operating component engages with the unlocking member to drive the unlocking member relative to the first component to the second position during movement. In the second operating state, the operating component disengages from the unlocking member. When the first component and the second component move relative to each other, the operating component switches to the second operating state.

[0006] In some embodiments, the operating component includes at least a coupling member having an engagement portion. In a first operating state, the engagement portion engages with the unlocking member to drive the unlocking member to move relative to the first component when the operating component moves. In a second operating state, the engagement portion disengages from the unlocking member.

[0007] Specifically, the locking device further includes a second reset member, which is used to drive the unlocking member to move from the second position toward the first position. The operating component is in the second working state, and the unlocking member is held in the first position under the action of the second reset member.

[0008] In some embodiments, when the unlocking member moves along the first direction, it moves from the first position to the second position. After reaching the second position, when the unlocking member continues to move along the first direction, it drives the locking member to move from the locked position to the unlocked position. The unlocking member is provided with an abutment portion. In the first working state, the engagement portion abuts against the abutment portion along the first direction, so that when the operating component moves, it drives the unlocking member to move synchronously. In the second working state, the engagement portion deviates from the abutment portion in a direction perpendicular to the first direction.

[0009] Specifically, the operating component includes an operating member, and the engaging member is movably disposed on the operating member. In the first operating state, the engaging member is in an engaged position; in the second operating state, the engaging member is in a non-engaged position; when the first component moves relative to the second component, the second component drives the engaging member to move and causes the engaging member to switch to the non-engaged position.

[0010] In some embodiments, the engaging member is rotatably connected to the operating member, and during relative movement between the first component and the second component, the second component drives the engaging member to rotate and switch between the engaging position and the non-engaged position.

[0011] In some embodiments, the engaging member is slidably connected to the operating member, and during relative movement between the first component and the second component, the second component drives the engaging member to slide and switch between the engaging position and the non-engaged position.

[0012] In some embodiments, the first component and the second component are movably connected along a first direction, the connector has a second engaging portion, and the second component is provided with a first mating structure and a second mating structure along the first direction. When the second engaging portion and the first mating structure are engaged with each other, the connector is in the engaging position; when the second engaging portion and the second mating structure are engaged with each other, the connector is in the non-engaged position; wherein the first mating structure is concave or convex toward the first component compared to the second mating structure.

[0013] In some embodiments, a boss is fixedly provided on the second joint portion, and a guide groove extending along the first direction is provided on the second component. The boss and the guide groove are slidably engaged. The guide groove includes a straight guide groove portion and a recessed portion. The depth of the recessed portion is greater than the depth of the straight guide groove portion. The recessed portion constitutes the first mating structure, and the straight guide groove portion constitutes the second mating structure.

[0014] In some embodiments, the first component and the second component are movably connected along a first direction, the connector has a second engagement portion, and the second component is provided with a drive structure that cooperates with the second engagement portion. During the relative movement of the first component and the second component, the drive structure acts on the second engagement portion to cause the connector to move and switch between the engagement position and the non-engagement position.

[0015] In some embodiments, at least one set of inclined structures is provided between the second joint and the second component, such that when the second joint moves relative to the second component, the inclined structures can drive the joint to switch to the non-joining position. The inclined structures include a first inclined surface provided on the second component, and the driving structure includes the first inclined surface.

[0016] In some embodiments, the second component is provided with two or more of the said mating parts, and when the first component and the second component move relative to each other, the locking member is located between two of the said mating parts; each of the said mating parts is provided with a corresponding driving structure; or the driving structure is provided between two of the said mating parts.

[0017] In some embodiments, the engaging member is rotatably disposed on the operating member about a rotation axis, the engaging portion is spaced apart from the axis of rotation, the second engaging portion and the engaging portion are disposed on opposite sides of the rotation axis, the engaging member switches between the engaging position and the non-engaging position during rotation about the rotation axis, wherein the axis of rotation is perpendicular to the first direction; the operating component further includes a third reset member, the third reset member being used to drive the engaging member to rotate about the rotation axis toward the engaging position.

[0018] In some embodiments, the unlocking member is provided with a first driving structure, and the locking member is provided with a driven structure. When the unlocking member is in the first position, the first driving structure and the driven structure are disengaged. When the unlocking member is in the second position, the first driving structure and the driven structure cooperate with each other so that when the unlocking member moves, it drives the locking member to move from the locked position to the unlocked position. The movement direction of the unlocking member is perpendicular to the movement direction of the locking member.

[0019] In some embodiments, the mating portion is at least two locking slots provided on the second component, and the locking member has a locking portion that can be mated and inserted into the locking slots, such that when the locking portion is inserted into one of the locking slots, the first component and the second component are locked together.

[0020] In some embodiments, the first component and the second component are slidably disposed relative to each other in the vertical direction, and a plurality of the mating portions are distributed at intervals in the vertical direction on the second component, wherein the unlocking member is configured to switch from the first position to the second position when moving upward.

[0021] Another object of the present invention is to provide a sleeping basket device.

[0022] To achieve the above objectives, the technical solution adopted by the present invention is: a sleeping basket device, comprising a support frame having a accommodating space, an adjustment seat disposed on the support frame, a connecting seat slidably connected to the adjustment seat, and a locking device disposed between the connecting seat and the adjustment seat for locking the two together, wherein the locking device is as described above.

[0023] Another object of the present invention is to provide a vehicle.

[0024] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a carrier, comprising a support frame and a carrying device disposed on the support frame, the support frame comprising a support frame body, a connecting seat fixed on the support frame body, an adjusting seat slidably connected to the connecting seat, and a locking device disposed between the connecting seat and the adjusting seat for locking the two together, the carrying device being mounted on the adjusting seat, wherein the locking device is as described above.

[0025] In some embodiments, the support frame body includes: A first support, wherein a first wheel assembly is provided at the bottom of the first support; The second bracket has a second wheel assembly at its bottom; A connecting component is movably connected between the first bracket and the second bracket; The connecting seat is fixedly disposed on the upper part of the first bracket, and the upper part of the second bracket is rotatably connected to the adjusting seat. The adjusting seat has at least a first height position and a second height position on the connecting seat. When the adjusting seat changes from the first height position to the second height position, the distance between the first wheel assembly and the second wheel assembly in the front-rear direction changes, and the support frame changes from the first form to the second form.

[0026] In some embodiments, the adjusting seat and the connecting seat are slidably connected in the vertical direction, and a guide structure is provided between the adjusting seat and the connecting seat to provide relative sliding guidance between the two in the vertical direction. When the support frame is transformed from the first form to the second form, the position of the connecting seat remains unchanged, and the adjusting seat slides relative to the connecting seat to transform from the first height position to the second height position.

[0027] In some embodiments, the connection assembly includes a connection frame, one end of which is rotatably connected to the first support, and the other end of which is rotatably connected to the second support.

[0028] Due to the application of the above technical solution, the present invention has the following advantages: The locking device of the present invention, by driving the unlocking member to move to the second position to cooperate with the locking member, can drive the locking member to move to the unlock position, thereby unlocking the locking device. After unlocking, during the relative movement of the first and second components, the unlocking member is in the first position. At this time, the unlocking member and the locking member are disengaged, and the unlocking member will not interfere with the locking member. If the locking member moves to the position corresponding to the mating part, the locking member can move accurately and quickly to the mating part and cooperate with it, making the locking device more stable and secure.

Detailed Implementation

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] See Figures 1 to 5The illustrated carrier includes a sleeping basket assembly. The sleeping basket assembly comprises a support frame with a accommodating space, an adjusting seat 5 mounted on the support frame, and a connecting seat 4 slidably connected to the adjusting seat 5. The position of the accommodating space can be adjusted by sliding the adjusting seat 5 relative to the connecting seat 4. A locking device is provided between the adjusting seat 5 and the connecting seat 4 to lock them together. The following description uses the locking device in the sleeping basket assembly as an example to illustrate one such locking device.

[0033] Specifically, in the bassinet device, one of the adjusting seat 5 and the connecting seat 4 constitutes a first component, and the other constitutes a second component. A locking device is used for locking the first component and the second component. In this embodiment, the locking device includes a locking member 51 and a mating part. The locking member 51 is movably disposed on the first component and moves between a locked position and an unlocked position on the first component. The mating part is disposed on the second component. When the locking member 51 is in the locked position, it can engage with the mating part to lock the device. When the locking member 51 is in the unlocked position, it disengages from the mating part, causing the locking device to unlock. The locking device also includes a first reset member 52, which drives the locking member 51 to move toward the locked position.

[0034] In this embodiment, the locking device further includes an unlocking member 53, which is movably disposed on the first component. The unlocking member 53 has at least a first position and a second position on the first component. When the unlocking member 53 is in the first position, it disengages from the locking member 51, and the two do not interfere with each other. When the unlocking member 53 is in the second position, it cooperates with the locking member 51, so that when the unlocking member 53 moves, it can drive the locking member 51 from the locked position to the unlocked position, thereby achieving unlocking. In this embodiment, after the first component and the second component have unlocked, when the first component and the second component move relative to each other, the unlocking member 53 is in the first position, and it disengages from the locking member 51. This allows the locking member 51 to quickly and accurately cooperate with the mating part without interference when the locking member 51 aligns with the mating part again, thereby completing the locking.

[0035] In this embodiment, the locking device includes a second reset member 54, which drives the unlocking member 53 to move from the second position toward the first position. This allows the unlocking member 53 to disengage from the locking member 51 under the drive of the second reset member 54 without any external force, thereby automatically eliminating interference with the locking member 51 and ensuring the stability and security of the locking device. Specifically, in this embodiment, when the first component and the second component move relative to each other, the second reset member 54 acts on the unlocking member 53, causing the unlocking member 53 to move to the first position.

[0036] In this embodiment, see Figure 9 , Figure 10 As shown, the first component includes a main body 501 and a housing 502. The housing 502 is connected to the main body 501, and a mounting cavity is formed between the housing 502 and the main body 501. The locking member 51 and the unlocking member 53 are both located within the mounting cavity. In this embodiment, the locking member 51 has a locking part 511, and the housing 502 is provided with a first through hole 503. When the locking member 51 is in the locked position, the locking part 511 extends out from the first through hole 503 and cooperates with the mating part.

[0037] In this embodiment, the mating part is a locking groove 42 provided on the second component. The locking part 511 can be inserted into the locking groove 42. When the locking part 511 is inserted into the locking groove 42, the first component and the second component can be locked together. Specifically, when the locking member 51 is in the locked position, the locking part 511 can extend from the first through hole 503 and be inserted into the locking groove 42, thereby achieving the locking of the first component and the second component.

[0038] In this embodiment, the unlocking member 53 is provided with a first driving structure, and the locking member 51 is provided with a driven structure. When the unlocking member 53 is in the first position, the first driving structure and the driven structure are disengaged. When the unlocking member 53 is in the second position, the first driving structure and the driven structure cooperate with each other, so that when the unlocking member 53 moves, it drives the locking member 51 from the locked position to the unlocked position. In this embodiment, the movement direction of the unlocking member 53 and the movement direction of the locking member 51 are perpendicular to each other. Specifically, the unlocking member 53 is arranged to move along the first direction, and the locking member 51 can be arranged to move perpendicular to the first direction.

[0039] In this embodiment, see Figure 11 As shown, the driven structure is a mating inclined surface 512 disposed on the locking member 51, and the first driving structure is a driving inclined surface 532 disposed on the unlocking member 53. The driving inclined surface 532 and the mating inclined surface 512 each extend obliquely along the first direction along the movement direction of the locking member 51. When the unlocking member 53 moves along the first direction, the driving inclined surface 532 can slide in cooperation with the mating inclined surface 512, thereby driving the locking member 51 to move perpendicular to the first direction, and then switch to the unlocked position.

[0040] In this embodiment, the locking device further includes an operating component movably disposed on the first component. The operating component is configured to engage with the unlocking member 53, enabling it to move relative to the first component during movement. The user can control the unlocking member 53 and unlock the locking device via the operating component. Specifically, in this embodiment, during the process of the user controlling the unlocking member 53 to unlock the locking device via the operating component, the unlocking member 53 first moves to the second position to engage with the locking member 51, and then the unlocking member 53 can drive the locking member 51 to move. Preferably, after the user completes the unlocking operation and the first and second components are unlocked, the operating component can disengage from the unlocking member 53, allowing the unlocking member 53 to move to the first position under the drive of the second reset member 54, thereby disengaging from the locking member 51. Thus, when the locking device locks the first and second components again, the unlocking member 53 will not interfere with the locking member 51. Under the drive of the first reset member 52, the locking member 51 can accurately and quickly approach the engaging part and engage with it, ensuring the sensitivity and stability of the locking device, thereby ensuring security.

[0041] In this embodiment, the operating component has a switchable first operating state and a second operating state. In the first operating state, the operating component and the unlocking member 53 are engaged, and the operating component 53 can be moved relative to the first component to a second position during movement. In the second operating state, the operating component and the unlocking member 53 are disengaged. In this embodiment, the operating component switches to the second operating state when the first component and the second component move relative to each other.

[0042] In this embodiment, the second component has two or more mating parts. When the first component and the second component are unlocked and during the process of driving the first component and the second component to move relative to each other, the locking member 51 moves between the two mating parts. At this time, the operating component switches to the second working state and disengages from the unlocking member 53. The unlocking member 53 can switch to the first position under the drive of the second reset member 54. Specifically, see Figure 8 As shown, the second component has two locking grooves 42 spaced apart along the first direction. When the first component and the second component are driven to move relative to each other, the locking member 51 moves between the two locking grooves 42.

[0043] In this embodiment, the operating component includes at least a connecting member 55, which has a connecting portion 551. In a first operating state, the connecting portion 551 engages with the unlocking member 53, so that when the operating component moves, the unlocking member 53 moves relative to the first component, thereby enabling unlocking. In a second operating state, the connecting portion 551 disengages from the unlocking member 53, and the unlocking member 53 can be switched and held in a first position under the action of the second reset member 54. At this time, the unlocking member 53 will not interfere with the locking member 51. In this embodiment, when the operating component is in the second operating state, the unlocking member 53 is held in the first position under the action of the second reset member 54.

[0044] In this embodiment, the operating component further includes an operating member 56, and an engaging member 55 is movably disposed on the operating member 56. When the operating member 56 moves relative to the first component, it enables the engaging member 55 to move and allows the engaging member 55 to switch between two states: disengaging from the unlocking member 53 and engaging with the unlocking member 53.

[0045] In this embodiment, when the unlocking member 53 moves along the first direction, it moves from the first position to the second position. When the unlocking member 53 reaches the second position and continues to move along the first direction, it drives the locking member 51 to move from the locked position to the unlocked position.

[0046] In this embodiment, when the locking device is in the locked state, the engaging member 55 and the unlocking member 53 disengage from each other to avoid accidental activation, further improving the security and stability of the lock. When unlocking, as the operating member 56 moves relative to the first component along the first direction, it first causes the engaging member 55 to switch from disengaging from the unlocking member 53 to engaging with the unlocking member 53. Then, the engaging member 55 can drive the unlocking member 53 to move. Specifically, when it is necessary to unlock the device, the user only needs to drive the operating member 56 to move along the first direction. The engaging member 55 first engages with the unlocking member 53, and then the operating member 56 can drive the unlocking member 53 to move along the first direction together. During the movement of the unlocking member 53 along the first direction, it first moves to the second position to complete its interaction with the locking member 51. Then, the unlocking member 53 continues to move and drives the locking member 51 to the unlocked position. The entire process requires only one step from the user—driving the operating member 56 along the first direction—making the operation simple.

[0047] In this embodiment, the coupling member 55 and at least part of the operating member 56 are located within the mounting cavity. In this embodiment, the upper part of the operating member 56 is provided with a handle 561, which is located outside the mounting cavity, making it convenient for the user to drive the operating member 56. Specifically, the user can unlock the locking device by pushing or pulling the handle 561.

[0048] In this embodiment, the coupling member 55 has an engaging position and a non-engaging position. In a first operating state, the coupling member 55 is in the engaging position, and in a second operating state, the coupling member 55 is in the non-engaging position. When the operating member 56 moves relative to the first component, it causes the coupling member 55 to switch between the engaging position and the non-engaging position, making the operation simple. In this embodiment, see [reference needed]. Figure 10 As shown, the unlocking member 53 is provided with an abutment portion 531. When the engaging member 55 is in the engaging position, see [reference needed]. Figure 16 , Figure 17 As shown, the engaging portion 551 abuts against the abutting portion 531 along the first direction, so that when the operating member 56 moves along the movement direction, it drives the unlocking member 53 to move synchronously. When the engaging member 55 is in the non-engaged position, see... Figures 18 to 20 As shown, the engaging portion 551 deviates from the abutting portion 531 in a direction perpendicular to the first direction. At this time, the engaging member 55 disengages from the unlocking member 53, and the unlocking member 53 can move to the first position under the drive of the second reset member 54.

[0049] In this embodiment, when the first component moves relative to the second component, the second component drives the engaging member 55 to move, causing the engaging member 55 to switch to a non-engaged position. In some embodiments, the engaging member 55 is rotatably connected to the operating member 56, and during the relative movement of the first and second components, the second component drives the engaging member 55 to rotate, switching between an engaged position and a non-engaged position. In other embodiments, the engaging member 55 is slidably connected to the operating member 56, and during the relative movement of the first and second components, the second component drives the engaging member 55 to slide, switching between an engaged position and a non-engaged position.

[0050] In this embodiment, the engaging member 55 is rotatably disposed on the operating member 56 about the rotation axis 550. The engaging portion 551 is spaced apart from the axis of rotation 550. During the rotation of the engaging member 55 about the rotation axis 550, it switches between an engaging position and a non-engaged position. Specifically, the axis of rotation 550 is perpendicular to the first direction. In this embodiment, the operating component also includes a third reset member 57, which is used to drive the engaging member 55 to rotate about the rotation axis 550 and move towards the engaging position.

[0051] In this embodiment, the engaging member 55 also has an initial position. When the locking device is in the locked state, the engaging member 55 is disengaged from the unlocking member 53, and the operating component is in the second working state, but the engaging member 55 is in the initial position. See also Figures 12 to 15As shown, the initial position of the coupling member 55 is the same as that of the coupling member 55 in the engaged position, but the initial position of the coupling portion 551 is spaced apart from the abutment portion 531 along the first direction, and the abutment portion 531 is located on the path of the coupling portion 551 moving along the first direction. When the coupling member 55 is moved along the first direction by the operating member 56, and the coupling member 551 comes into contact with the abutment portion 531, the coupling member 55 changes to the engaged position.

[0052] In this embodiment, during the movement of the operating member 56 along the first direction, the engaging member 55 changes from an initial position to an engaged position and then to a non-engaged position. After the engaging member 55 changes from its initial position to the engaged position, the operating member 56 can drive the unlocking member 53 to move together. While the engaging member 55 is in the engaged position, the unlocking member 53 completes the transition from a first position to a second position and drives the locking member 51 to the unlocked position. After the unlocking operation is completed, the engaging member 55 changes to the non-engaged position and disengages from the unlocking member 53, and the unlocking member 53 can change to the first position and disengage from the locking member 51.

[0053] In this embodiment, the coupling member 55 further has a second coupling portion 552, which is disposed on opposite sides of the coupling portion 551 on the rotating shaft 550. A third reset member 57 is disposed between the second coupling portion 552 and the operating member 56. The third reset member 57 drives the coupling member 55 to rotate and move it to the coupling position through a lever principle. In this embodiment, the first reset member 52, the second reset member 54, and the third reset member 57 are all springs.

[0054] In this embodiment, the second component is provided with a drive structure that cooperates with the second engaging portion 552. After the first and second components are unlocked, during the relative movement of the first and second components, the drive structure acts on the second engaging portion 552 to cause the engaging member 55 to move and switch between an engaged position and a non-engaged position. Specifically, during the relative movement of the first and second components, the drive structure acts on the second engaging portion 552 to cause the engaging member 55 to swing. Thus, during the relative movement of the first and second components, the cooperation between the drive structure and the second engaging portion 552 enables the unlocking member 53 to move to a first position and disengage from the locking member 51. In some embodiments, the drive structure extends toward or away from the first component along a direction perpendicular to the first direction.

[0055] In this embodiment, each mating part is provided with a corresponding driving structure. When the locking member 51 disengages from any mating part, when the first part moves relative to the second part, a driving structure engages with the engaging member 55 and drives it to switch to a non-engaged position. In some embodiments, the driving structure is provided between the two mating parts. For example, the driving structure is a protrusion provided between the two mating parts, extending towards the first part; or, the driving structure is a groove provided between the two mating parts, recessed and extending away from the first part.

[0056] In this embodiment, at least one set of inclined surface structures is provided between the second joint 552 and the second component, so that when the second joint 552 moves relative to the second component, the inclined surface structures can drive the joint 55 to a non-joined position. The inclined surface structures include a first inclined surface 4311 provided on the second component and a second inclined surface 5531 provided on the second joint 552, wherein the first inclined surface 4311 constitutes the aforementioned driving structure. In this embodiment, the first inclined surface 4311 and the second inclined surface 5531 extend obliquely perpendicular to the first direction.

[0057] In this embodiment, the first component and the second component are slidably connected along a first direction, or the first component and the second component are slidably disposed parallel to the first direction. In this embodiment, the second component is provided with a first mating structure and a second mating structure along the first direction. When the second joint 552 mates with the first mating structure, the joint member 55 is in the mating position. When the second joint 552 mates with the second mating structure, the joint member 55 is in the non-matting position.

[0058] In this embodiment, during the unlocking process of the locking device, the second engaging portion 552 remains engaged with the first engaging structure, thereby enabling the locking device to be unlocked by the unlocking member 53. When the unlocking of the locking device is completed and the first component and the second component are driven to move relative to each other, the second engaging portion 552 disengages from the first engaging structure and engages with the second engaging structure. At this time, the engaging member 55 disengages from the unlocking member 53, and the unlocking member 53 disengages from the locking member 51.

[0059] Specifically, the first mating structure is recessed or convex towards the first component compared to the second mating structure. In this embodiment, the second mating structure protrudes towards the first component compared to the first mating structure. Thus, when the second joint 552 moves from mating with the first mating structure to mating with the second mating structure, the second mating structure drives the second joint 552 to move towards the first component, causing the joint member 55 to rotate, thereby causing the joint member 55 to switch to a non-joined position.

[0060] In this embodiment, the housing 502 is further provided with a second through hole 504. Under the drive of the third reset member 57, the second engaging portion 552 can extend out from the second through hole 504, so that the engaging member 55 is in the initial position or the engaged position. When the second engaging portion 552 engages with the second mating structure, the second mating structure drives the second engaging portion 552 back into the mounting cavity. Specifically, a boss 553 is fixedly provided on the second engaging portion 552. Under the drive of the third reset member 57, the boss 553 can extend out from the second through hole 504.

[0061] In this embodiment, see Figure 8 As shown, the second component has a guide groove 43 extending along a first direction, and the boss 553 is slidably fitted with the guide groove 43. The guide groove 43 includes a straight guide groove portion 432 and a recessed portion 431. The depth of the recessed portion 431 is greater than the depth of the straight guide groove portion 432. The recessed portion 431 forms a first mating structure, and the straight guide groove portion 432 forms a second mating structure. The recessed portion 431 and the straight guide groove portion 432 are interconnected. Specifically, when the boss 553 is inserted into the recessed portion 431, the engaging member 55 is in an initial position or an engaged position. When the boss 553 moves from the recessed portion 431 to the straight guide groove portion 432, the engaging member 55 rotates around the rotation axis 550, causing the engaging member 55 to switch to a non-engaged position. The boss 553 can slide along the first direction in the recessed portion 431, realizing the transition between the initial position and the engaged position.

[0062] In this embodiment, two mating parts are provided at intervals along the first direction on the first component. Correspondingly, the guide groove 43 has two grooves 431 distributed at intervals along the first direction, and the straight guide groove 432 extends along the first direction and is located between the two grooves 431. The straight guide groove 432 connects the two grooves 431.

[0063] In this embodiment, see Figure 23 As shown, a first inclined surface 4311 is provided at the junction of the groove portion 431 and the linear guide groove portion 432. In this embodiment, see... Figure 8 , Figure 10 As shown, the boss 553 is provided with a second inclined surface 5531. Specifically, the boss 553 is provided with a second inclined surface 5531 on each of its two sides along the first direction, so that when the engaging member 55 reciprocates relative to the second component along the first direction, it can be driven to switch to a non-engaged position by engaging with the inclined surface. The cooperation between the first inclined surface 4311 and the second inclined surface 5531 allows the boss 553 to exit from the groove 431 and enter the straight guide groove 432 when sliding relative to the guide groove 43, thereby causing the engaging member 55 to switch to a non-engaged position.

[0064] In this embodiment, the first direction is the up-down direction. The first component and the second component are slidably arranged relative to each other in the up-down direction, and multiple mating parts are distributed at intervals on the second component in the up-down direction.

[0065] In this embodiment, the unlocking member 53 is configured to change from the first position to the second position when it moves upward. By driving the unlocking member 53 to move upward, the unlocking member 53 can cooperate with the locking member 51. During the process of the unlocking member 53 continuing to move upward, the locking member 51 moves to the unlock position by driving the inclined surface 532 and the cooperating inclined surface 512 to cooperate with each other.

[0066] In this embodiment, the operating component is configured to move the unlocking member 53 when it moves upward relative to the first component. Specifically, the user can unlock the locking device by pulling the handle 561 upward.

[0067] In this embodiment, the operating member 56 can also drive the first component to move relative to the second component. After driving the operating member 56 to move in the first direction and unlocking the locking device, continuing to drive the operating member 56 to move can directly drive the first component to move relative to the second component, and cause the locking member 51 to move towards another mating part. When the first component moves to the desired position relative to the second component, the locking member 51 engages with the corresponding mating part, and the first component and the second component are locked again. In summary, the user can achieve multiple functions such as unlocking the locking device and driving the first component to move relative to the second component by controlling the operating member 56, making operation more convenient.

[0068] In this embodiment, the operating member 56 is movably disposed on the main body 501 along a first direction. The locking device further includes an elastic member 58 disposed between the operating member 56 and the main body 501, which is used to drive the operating member 56 to reset. When the locking device is unlocked by the operating member 56, the main body 501 can be driven to move together with the operating member 56 while the operating member 56 is being driven to move, thereby driving the first component to move relative to the second component. When the first component and the second component are locked again, the operating member 56 is released, and the elastic member 58 drives the operating member to reset. In some embodiments, one of the operating member 56 and the main body 501 is provided with a driving structure and the other is provided with a limiting structure. When the operating member 56 is driven to move along the first direction and the locking device is unlocked, the driving structure and the limiting structure can cooperate with each other to make the first component and the operating member 56 move synchronously when the operating member 56 is being driven to move. In this embodiment, the elastic member 58 is a spring.

[0069] In this embodiment, the specific working principle of the locking device is as follows: In the initial state, see Figures 12 to 15As shown, the locking part 511 is inserted into the lower locking groove 42, and the unlocking member 53 is in the first position, disengaging from the locking member 51. The boss 553 of the engaging member 55 is inserted into the recess 431, and the engaging member 55 is in the initial position. At this time, the abutment 531 is located on the path of the upward movement of the engaging member 551, and the engaging member 551 is not engaged with the abutment 531. This arrangement avoids the engaging member 55 directly driving the unlocking member 53 after the operating member 56 is disturbed, thereby reducing the security risk. In some embodiments, in the initial state, the engaging member 55 is in the engaged position, and the abutment 531 is in contact with the engaging member 551.

[0070] When the user needs to unlock the locking device and drives the first component to move relative to the second component, the user drives the operating member 56 upward. During this process, the engaging member 55 moves upward with the operating member 56 and contacts the abutment portion 531. The engaging member 55 then switches to the engaged position, which drives the unlocking member 53 to move upward. Driven by the engaging member 55, the unlocking member 53 first moves to the second position to engage with the locking member 51. Then, as the unlocking member 53 continues to move upward, the driving inclined surface 532 engages with the mating inclined surface 512, causing the locking member 51 to switch to the unlocked position. During the above process, the boss 553 slides in the groove portion 431, and the boss 553 is always located in the groove portion 431.

[0071] After the locking member 51 is switched to the unlocked position, thus unlocking the locking device, the first component can move relative to the second component along with the operating member 56, or through the cooperation of the cooperating structure and the limiting structure provided between the main body 501 and the operating member 56. At this time, as the operating member 56 drives the engaging member 55 to continue moving, the boss 553 moves from the groove 431 to the linear guide groove 432, and the engaging member 55 is driven by the driving structure to rotate around the rotation axis 550 and switch to the non-engaged position. After switching to the non-engaged position, the engaging part 551 disengages from the abutting part 531, and under the drive of the second reset member 54, the unlocking member 53 resets downward to the first position, and the unlocking member 53 disengages from the locking member 51, so that the locking member 51 can tend to move towards the locked position under the action of the first reset member 52.

[0072] As the first component continues to move, once it reaches the desired position, see [link to previous text]. Figure 21 , Figure 22 As shown, the locking member 51 corresponds to the new lock groove 42. Since the unlocking member 53 has disengaged from the locking member 51, the locking member 51 is inserted into the lock groove 42 without any other interference or resistance, thus locking the first component and the second component together.

[0073] In this embodiment, the adjusting seat 5 constitutes the first component, and the connecting seat 4 constitutes the second component. In this embodiment, the adjusting seat 5 of the bassinet device extends vertically, and the connecting seat 4 is slidably connected to the adjusting seat 5 along its length. The height of the accommodating space can be adjusted by driving the adjusting seat 5 and the connecting seat 4 to slide relative to each other. During the process of driving the operating component provided on the adjusting seat 5 to move upward, the adjusting seat 5 and the connecting seat 4 can be unlocked. After unlocking, the operating component can drive the adjusting seat 5 to slide relative to the connecting seat 4. After the adjusting seat 5 moves to the desired position, the locking member 51 can lock the two together again.

[0074] See Figures 1 to 5 As shown, the carrier includes a support frame 100 and a carrying device 200 mounted on the support frame 100. The support frame 100 includes a support frame body, a connecting seat 4 fixed to the support frame body, an adjusting seat 5 slidably connected to the connecting seat 4, and a locking device disposed between the connecting seat 4 and the adjusting seat 5 for locking the two together. In this embodiment, the carrying device 200 is mounted on the adjusting seat 5. As described above, the locking device allows the position of the carrying device 200 to be adjusted by driving the adjusting seat 5 to slide relative to the connecting seat 4. In this embodiment, the adjusting seat 5 extends vertically, and the connecting seat 4 is slidably connected to the adjusting seat 5 along its length. The height of the carrying device 200 can be adjusted by driving the adjusting seat 5 to slide relative to the connecting seat 4. Specifically, in this embodiment, the carrying device 200, the connecting seat 4, and the adjusting seat 5 together constitute the aforementioned sleeping basket device.

[0075] In this embodiment, the support frame body includes a first bracket 1, a second bracket 2, and a connecting assembly. The carrier in this embodiment is a trolley, which also includes a wheel assembly 300 disposed at the bottom of the support frame 100. The wheel assembly 300 includes a first wheel assembly 301 and a second wheel assembly 302. The first wheel assembly 301 is disposed at the bottom of the first bracket 1, and the second wheel assembly 302 is disposed at the bottom of the second bracket 2. The connecting assembly is movably connected between the first bracket 1 and the second bracket 2. Specifically, the connecting assembly includes a connecting frame 3, one end of which is rotatably connected to the first bracket 1, and the other end of which is rotatably connected to the second bracket 2. In some embodiments, the carrier is a seat, a bassinet, or a crib.

[0076] In this embodiment, see Figures 6 to 8 As shown, the connecting seat 4 is fixedly disposed on the upper part of the first bracket 1, and the upper part of the second bracket 2 is rotatably connected to the adjusting seat 5.

[0077] In this embodiment, the adjusting seat 5 has at least a first height position and a second height position on the connecting seat 4. When the adjusting seat 5 changes from the first height position to the second height position, the distance between the first wheel assembly 301 and the second wheel assembly 302 in the front-rear direction changes, and the support frame 100 changes from the first form to the second form. In this embodiment, the carrier, by driving the adjusting seat 5 to move relative to the connecting seat 4, changes the height position of the adjusting seat 5, which in turn drives the second bracket 2 to rotate relative to the adjusting seat 5, thereby adjusting the distance between the first wheel assembly 301 and the second wheel assembly 302. When the adjusting seat 5 changes between the first height position and the second height position, the height of the bearing device 200 also changes.

[0078] Specifically, in this embodiment, the first height position is higher than the second height position in the vertical direction. When the adjusting seat 5 is in the first height position, the first wheel assembly 301 and the second wheel assembly 302 have a first distance in the front-back direction. When the adjusting seat 5 is in the second height position, the first wheel assembly 301 and the second wheel assembly 302 have a second distance in the front-back direction, and the first distance is smaller than the second distance. When the adjusting seat 5 changes from the first height position to the second height position, see [reference needed]. Figure 3 , Figure 4 As shown, when the bearing device 200 moves downward, the distance between the first wheel assembly 301 and the second wheel assembly 302 increases, thus lowering the vehicle's center of gravity and increasing its wheelbase, resulting in greater stability. When the adjusting seat 5 changes from the second height position to the first height position, the bearing device 200 moves upward, decreasing the distance between the first wheel assembly 301 and the second wheel assembly 302. This raises the vehicle's center of gravity and reduces the wheelbase, increasing the vehicle's maneuverability.

[0079] In this embodiment, when the vehicle is in its deployed state, the length extension directions of the first support 1 and the second support 2 form an angle α. When the adjusting seat 5 changes from a first height position to a second height position, the angle α changes. When the adjusting seat 5 changes between different height positions, the angle α between the first support 1 and the second support 2 changes, thereby adjusting the distance between the first wheel assembly 301 and the second wheel assembly 302. Specifically, in this embodiment, when the adjusting seat changes from the first height position to the second height position, the angle α increases.

[0080] In this embodiment, when the support frame 100 transitions from the first form to the second form, the angle between the first support 1 and the horizontal plane remains unchanged, while the angle between the second support 2 and the horizontal plane changes. When the support frame 100 transitions between the first and second forms, the state of the first support 1 remains unchanged, while the second support 2 moves upward or downward and rotates. In this embodiment, when the support frame 100 transitions from the first form to the second form, the position of the connecting seat 4 remains unchanged, while the adjusting seat 5 slides relative to the connecting seat and transitions from the first height position to the second height position.

[0081] In this embodiment, the adjusting seat 5 always extends vertically, and a guide structure is provided between the adjusting seat 5 and the connecting seat 4 to provide relative sliding guidance between the two in the vertical direction. Specifically, see Figure 8 As shown, the guide structure includes a guide groove 41 disposed on the connecting seat 4 in the vertical direction, and the adjusting seat 5 is slidably engaged with the guide groove 41 in the vertical direction.

[0082] In this embodiment, the support device 200 includes a support frame rotatably connected to the adjustment seat 5, allowing the support device 200 to switch between a seated usage mode providing sitting support and a bassinet usage mode providing reclining support. Specifically, the support frame includes a surrounding frame 7 and a support member disposed on the surrounding frame 7, with the surrounding frame 7 rotatably connected to the adjustment seat 5. In this embodiment, two adjustment seats 5 are spaced apart on the support frame 100, the surrounding frame 7 is disposed between the two adjustment seats 5, and both sides of the surrounding frame 7 are rotatably connected to the two adjustment seats 5 respectively around a rotation center line extending in the same direction.

[0083] In this embodiment, in bassinet usage mode, see [link to relevant documentation]. Figure 2 , Figure 6 As shown, the supporting member is located below the frame 7, and the supporting member and the frame 7 enclose the aforementioned accommodating space, with the opening of the accommodating space facing upwards. See also Figure 1 As shown, in the seating mode, the frame 7 extends obliquely in the vertical direction, with the opening of the accommodating space facing forward. In some embodiments, the supporting member is a fabric cover fixed to the frame 7; in the bassinet mode, the fabric cover surrounds the periphery and lower part of the supporting space; in the seating mode, the fabric cover surrounds the periphery and rear of the supporting space. In other embodiments, the supporting member is a combination of a fabric cover and a support plate; in the bassinet mode, the fabric cover surrounds the periphery of the supporting space, and the support plate is located below the supporting space.

[0084] In this embodiment, the support frame 100 also includes a push rod frame 6, which allows the user to drive the vehicle to move. Specifically, see... Figure 1 , Figure 5As shown, in this embodiment, the push rod frame 6 is rotatably connected to the first bracket 1, and the vehicle has a first mode and a second mode. In the first mode, see... Figures 1 to 4 As shown, the push rod 6 extends upwards from front to back. In this mode, the user can push the vehicle forward using the push rod 6. Rotating the push rod 6 forward changes its extension direction to forward and upward, at which point the vehicle switches to the second mode, see [link to previous section]. Figure 5 As shown, in this mode, the user can pull the vehicle forward using the push rod 6.

[0085] In some embodiments, the push rod 6 is connected to the connecting seat 4. Specifically, the push rod 6 is rotatably connected to the connecting seat 4, and the push rod 6 can be flipped to give the vehicle a first mode and a second mode. In the first mode, it is a normal vehicle that can be moved by pushing the push rod 6. By rotating the push rod 6 forward in the direction of travel, the vehicle is switched to the second mode, in which the user moves by dragging the push rod 6.

[0086] In summary, the locking device of this embodiment can be driven to the unlocked state by pulling up the operating member 56, making operation simple. During the unlocking process and the relative position of the first and second components being adjusted by sliding relative to each other, the engaging member 55 and the unlocking member 53 disengage. The unlocking member 53 is driven to the first position by the second reset member 54, thereby disengaging the unlocking member 53 from the locking member 51. Thus, when relocking the first and second components, the locking member 51 is not interfered with by the unlocking member 53, and it can be accurately and quickly inserted into the lock groove 42.
