[0080] Example 1

[0081] like Figure 1 As shown, this embodiment provides a child vehicle that simplifies the disassembly and assembly of child seats and improves ease of installation and removal. The child vehicle includes a base (not shown), a vehicle body 2, a first locking mechanism, a first unlocking mechanism, and a second unlocking mechanism.

[0082] The vehicle body 2 is detachably mounted on the base. A first locking mechanism is disposed on the vehicle body 2, and the first locking mechanism has a locking position for locking the vehicle body 2 and the base, and an unlocking position for unlocking the vehicle body 2 and the base. A first unlocking mechanism is disposed on the vehicle body 2, and the first unlocking mechanism is used to drive the first locking mechanism to move towards the unlocking position and keep the first locking mechanism in the unlocking position. A second unlocking mechanism is disposed on the base, and the second unlocking mechanism is used to unlock the first unlocking mechanism, so that the first locking mechanism moves towards the locking position.

[0083] Optionally, the aforementioned base can be a stroller frame, a support for fixing the vehicle body 2, or a car seat, etc. The vehicle body 2 can be a baby carrier, bassinet, child seat, etc.

[0084] In this embodiment, when the vehicle body 2 is installed on the base, the first locking mechanism is in the locked position to ensure the stability of the vehicle body 2 on the base. When it is necessary to remove the vehicle body 2, the first unlocking mechanism is operated to drive the first locking mechanism to move towards the unlocked position. Since the first unlocking mechanism can unlock and hold the first locking mechanism in the unlocked position, the vehicle body 2 and the base can remain in the unlocked state. That is, the user does not need to manually keep the first locking mechanism in the unlocked position all the time, thus freeing up their hands to remove the vehicle body 2 from the base, simplifying the disassembly operation steps and making the disassembly of the vehicle body 2 more convenient and faster. In addition, during the removal of the vehicle body 2, the second unlocking mechanism on the base can release the first unlocking mechanism from the first locking mechanism, thereby restoring the first locking mechanism to the locked position and the first unlocking mechanism to the initial position, facilitating the next locking of the vehicle body 2 to the base.

[0085] Optionally, see Figure 1 , Figure 2 and Figure 3 The vehicle body 2 is provided with a first connecting seat 21, and both a first locking mechanism and a first unlocking mechanism are movably disposed on the first connecting seat 21; a second connecting seat 11 is provided on the base, and a second unlocking mechanism is disposed on the second connecting seat 11. When the first connecting seat 21 and the second connecting seat 11 are engaged, they are locked by the first locking mechanism. After the first unlocking mechanism unlocks the first locking mechanism, when the first connecting seat 21 and the second connecting seat 11 are disengaged, the second unlocking mechanism unlocks the first unlocking mechanism. Figure 3 , Figure 4 and Figure 5 As shown, when the first connecting seat 21 and the second connecting seat 11 are engaged, the first locking mechanism is in the locked position, and the first connecting seat 21 and the second connecting seat 11 are locked together, at which point the vehicle body 2 is locked to the base. When the first unlocking mechanism is operated to move the first locking mechanism to the unlocking position, after the first locking mechanism moves to the unlocking position, the first connecting seat 21 and the second connecting seat 11 are unlocked. At this time, the second connecting seat 11 can disengage from the first connecting seat 21, allowing the vehicle body 2 to detach from the base. During the process of the second connecting seat 11 disengaging from the first connecting seat 21, the second unlocking mechanism unlocks the first unlocking mechanism, so that the first locking mechanism and the first unlocking mechanism can return to their original positions, facilitating the next locking of the vehicle body 2 to the base.

[0086] Optionally, the vehicle body 2 is provided with first connecting seats 21 on at least two opposite sides, and the base is provided with second connecting seats 11 corresponding to at least two of the first connecting seats 21. A second locking mechanism 6 is provided between at least one first connecting seat 21 and its corresponding first unlocking mechanism, and the second connecting seat 11 is provided with the aforementioned second unlocking mechanism. The second locking mechanism 6 is used to lock the first unlocking mechanism, keeping it in the unlocked position, and the second unlocking mechanism is used to drive the second locking mechanism 6 to unlock the first unlocking mechanism.

[0087] That is, a second locking mechanism 6 can be provided on both sides of the first unlocking mechanism of the vehicle body 2, so that after the first locking mechanism is unlocked, both sides of the vehicle body 2 can remain in the unlocked state simultaneously, making it easier to remove the vehicle body 2. Of course, a second locking mechanism 6 can also be provided only on one side of the first unlocking mechanism of the vehicle body 2, so that the first locking mechanism on one side of the vehicle body 2 remains in the locked position after being unlocked. For the first locking mechanism on the other side of the vehicle body 2, the user can manually control the first unlocking mechanism with one hand to keep the first locking mechanism in the unlocked position, while the user's other hand lifts the vehicle body 2 from the base, which also simplifies the disassembly steps of the vehicle body 2 and makes the disassembly and assembly of the vehicle body 2 more convenient.

[0088] In addition, a second locking mechanism 6 is provided only on the first unlocking mechanism on one side of the vehicle body 2. When the first locking mechanism on one side of the vehicle body 2 is unlocked, the other side of the vehicle body 2 remains locked, making it difficult for the vehicle body 2 (such as a basket) to fall off the base (such as a frame), thus improving the safety of the vehicle.

[0089] During the process of removing the vehicle body 2, the second unlocking mechanism drives the second locking mechanism 6 to move toward the position of unlocking the first unlocking mechanism, so as to release the first unlocking mechanism from the first locking mechanism, thereby restoring the first unlocking mechanism to its initial position, so as to facilitate the next locking or unlocking of the vehicle body 2 with the base.

[0090] Optionally, see Figure 1 The vehicle body 2 includes a support base 22 and a handle 23 rotatably connected to the support base 22. Both ends of the handle 23 are rotatably connected to the support base 22 via a first connecting seat 21. The vehicle body 2 can be lifted by the handle 23, making it convenient for the user to move the vehicle body 2. By adjusting the rotation angle of the handle 23, the handle 23 can be folded up or unfolded, making it easier to store and use.

[0091] Furthermore, a locking tube 24 is also connected to the outer shell of the vehicle body 2. In other embodiments, the vehicle body 2 can also be fixed to the base by the locking tube 24.

[0092] Optionally, see Figure 2 , Figure 3 , Figure 4 and Figure 5 The first locking mechanism includes a first locking member 31 movably disposed on the first connecting seat 21 and a mating component 12 disposed on the second connecting seat 11. In the locked position, the first locking member 31 locks with the mating component 12, thereby locking the first connecting seat 21 and the second connecting seat 11 together and ensuring that the carrier body 2 is securely installed on the base. Further, the first unlocking mechanism includes a first unlocking member 41, which is movably disposed on the first connecting seat 21 along a preset direction. When the first unlocking member 41 moves along the preset direction, it drives the first locking member 31 to move in a direction disengaging from the mating component 12. During the unlocking operation, the user only needs to drive the first unlocking member 41 to move along the preset direction to unlock the first locking member 31, making the operation simple and easy. In this embodiment, the preset direction is... Figure 3 and Figure 4 Pressing down on the first unlocking component 41 in the up-down direction will unlock the first locking component 31.

[0093] Continue reading Figure 2 , Figure 3 , Figure 4 and Figure 5 Optionally, the first connecting seat 21 is provided with a insertion cavity 211, and the second connecting seat 11 can be inserted into or detached from the insertion cavity 211. The first locking member 31 is rotatably disposed within the insertion cavity 211. Further, the first locking member 31 is a locking hook, and the cooperating component 12 is a limiting block. When locked, the locking hook engages with the limiting block to prevent the second connecting seat 11 from detaching from the insertion cavity 211, ensuring stable insertion between the first connecting seat 21 and the second connecting seat 11. Figure 8 , Figure 9 and Figure 10 As shown, when the locking hook rotates to the unlocked position, the locking hook disengages from the limiting block. At this time, the locking hook releases its restriction on the second connecting seat 11, and the second connecting seat 11 can disengage from the insertion cavity 211. When the second connecting seat 11 is reinserted into the insertion cavity 211, the locking hook hooks back onto the limiting block to lock the first connecting seat 21 and the second connecting seat 11.

[0094] Further, see Figure 2 , Figure 5 and Figure 7 The lock hook is provided with a first rotating shaft 313, and the first connecting seat 21 is provided with a rotating hole. The first rotating shaft 313 is inserted into the rotating hole and rotates with the rotating hole to realize the lock hook swinging and switching between the locked position and the unlocked position.

[0095] Furthermore, an elastic reset member is provided between the locking hook and the inner wall of the insertion cavity 211, allowing the locking hook to rotate towards the hook-locking block under the elastic force of the reset member. During the unlocking process where the first unlocking member 41 drives the locking hook to rotate, the elastic reset member is compressed or stretched. When the second connecting seat 11 disengages from the insertion cavity 211 and releases the first unlocking member 41, the elastic reset member releases its elastic potential energy, causing the locking hook to rotate back towards the hook-locking block. The elastic reset member allows the locking hook to automatically return to its original position, facilitating the next locking of the first connecting seat 21 and the second connecting seat 11. For example, the elastic reset member is a compression spring or a tension spring.

[0096] In other embodiments, an elastic arm can also be provided on the hook, with the end of the elastic arm away from the hook abutting against the inner wall of the insertion cavity 211. The hook can rotate towards the hook-locking block under the elastic force of the elastic arm. During the unlocking process where the first unlocking member 41 drives the hook to rotate and unlock, the elastic arm is compressed and undergoes elastic deformation. When the force exerted by the first unlocking member 31 on the hook decreases or disappears, the elastic arm releases elastic potential energy, thereby driving the hook to rotate in the opposite direction and return to its original position. For example, the elastic arm is an arc-shaped plate that extends out from the upper end of the hook, with the arc-shaped convex surface of the arc-shaped plate facing the hook portion of the hook. This ensures that the arc-shaped plate is compressed and accumulates elastic potential energy when the hook is unlocked.

[0097] To ensure that the second connecting seat 11 can be smoothly inserted into the insertion cavity 211 and that the locking hook and the limiting block can be smoothly engaged, in this embodiment, as follows: Figure 2 and Figure 7 As shown, the locking hook is provided with a first guide surface 312, and the limiting block is provided with a second guide surface 121. The first guide surface 312 can slide and cooperate with the second guide surface 121 to guide the locking hook to engage with the limiting block. Specifically, as shown... Figure 16 As shown, during the insertion of the second connecting seat 11 into the insertion cavity 211, when the limiting block moves to contact the locking hook, the second guide surface 121 contacts the first guide surface 312. As the limiting block continues to move upward relative to the first connecting seat 21 with the second connecting seat 11, the second guide surface 121 slides into the first guide surface 312 to push the locking hook to rotate counterclockwise (during which the elastic reset member is compressed or stretched to store energy) until the second guide surface 121 disengages from the first guide surface 312 (e.g., Figure 14 As shown in the figure, when the limit block continues to move upward with the second connecting seat 11, the locking hook will rotate clockwise under the elastic force of the elastic reset member until the locking hook catches the limit block.

[0098] Optionally, see Figure 2 , Figure 3 , Figure 4 and Figure 5The first unlocking mechanism also includes a drive structure disposed between the first unlocking member 41 and the first locking member 31. When the first unlocking member 41 moves in a preset direction, it drives the drive structure to move so that the first locking member 31 moves in the direction of disengaging from the mating member 12, thereby unlocking the first locking mechanism.

[0099] Optionally, the driving structure includes a first engaging portion 411 disposed on the first unlocking member 41 and a second engaging portion 311 disposed on the first locking member 31. When the first unlocking member 41 moves in a preset direction, the first engaging portion 411 engages with the second engaging portion 311, causing the first locking member 31 to move in a direction disengaging from the engaging member 12. During the unlocking operation, the user only needs to drive the first unlocking member 41 to move in the preset direction to unlock the first locking member 31, making the operation simple and easy.

[0100] Further, see Figure 7 and Figure 12 The first mating part 411 is provided with a first guide surface 4111, and the second mating part 311 is provided with a second guide surface 3111. The first guide surface 4111 and the second guide surface 3111 are slidably engaged to drive the lock hook to rotate. Figure 5 As shown, when the lock hook is in the locked position, the first mating part 411 does not contact the second mating part 311. During the process of driving the first unlocking member 41 to move down, after the first guide surface 4111 contacts the second guide surface 3111, when the first unlocking member 41 continues to move down, the first guide surface 4111 slides into contact with the second guide surface 3111. The first guide surface 4111 will generate a pushing force on the second guide surface 3111 to drive the lock hook to rotate around its rotation axis.

[0101] In this embodiment, the first mating part 411 is provided with an arc-shaped groove to form an arc-shaped first guide surface 4111. The second mating part 311 is a cylinder protruding from the end of the locking hook 31, and the outer circumferential surface of the cylinder is the second guide surface 3111. Both the first guide surface 4111 and the second guide surface 3111 are designed as arc-shaped surfaces, allowing the locking hook to rotate along a preset trajectory. Figure 5 and Figure 7 As shown, when the lock hook is in the locked position, the second mating part 311 is located at the lower end of the first guide surface 4111. During the process of pressing down the first unlocking member 41, the first guide surface 4111 and the second guide surface 3111 slide into each other, and at the same time, the second mating part 311 moves upward relative to the first guide surface 4111, as shown. Figure 10 and Figure 12 As shown, the second mating part 311 moves to the upper end of the first guide surface 4111, and the locking hook rotates to the unlocked position.

[0102] In other embodiments, the first guide surface 4111 and the second guide surface 3111 may also be designed as inclined surfaces, as long as they can drive the lock hook to rotate around its axis of rotation.

[0103] Optionally, one of the inner walls of the first unlocking member 41 and the insertion cavity 211 is provided with a slider, and the other of the inner walls of the first unlocking member 41 and the insertion cavity 211 is provided with a groove. The slider is engaged with the groove and slides in a preset direction. The engagement between the slider and the groove guides the first unlocking member 41 to always move in the preset direction, preventing the first unlocking member 41 from shifting or deviating, and ensuring a smoother unlocking operation.

[0104] For example, a slider may be protruded on the first unlocking member 41, and a groove extending in a preset direction may be opened on the inner wall of the insertion cavity 211.

[0105] Optionally, see Figure 3 and Figure 8 The first connecting seat 21 is provided with an opening 213 communicating with the insertion cavity 211, and the first unlocking member 41 can extend at least partially through the opening 213. This arrangement facilitates the user to operate the first unlocking member 41 to drive the lock hook to unlock.

[0106] For example, the portion of the first unlocking member 41 extending out of the opening 213 is button-shaped, see reference. Figure 6 and Figure 11 The portion of the first unlocking member 41 located within the insertion cavity 211 is provided with a stop step 415. The stop step 415 can stop at the edge of the opening 213 to limit the movement of the first unlocking member 41 and prevent the first unlocking member 41 from disengaging from the opening 213.

[0107] Optionally, see Figure 3 and Figure 8 The second locking mechanism 6 includes a first limiting structure disposed in one of the first unlocking mechanism and the first connecting seat 21, and a second limiting structure disposed in the other of the first unlocking mechanism and the first connecting seat 21. During the process of the first unlocking mechanism driving the first locking mechanism to move towards the unlocked position, the first limiting structure can engage with the second limiting structure to lock the first unlocking mechanism. That is, when the first limiting structure engages with the second limiting structure, the position of the first unlocking mechanism is restricted, allowing the first locking mechanism to temporarily remain in the unlocked position, facilitating the removal of the device body 2.

[0108] In this embodiment, see Figure 3 and Figure 8 The first limiting structure includes a second locking member 61 rotatably disposed on the first unlocking mechanism. The second locking member 61 has a limiting protrusion 611. The second limiting structure includes a first limiting hole 212 disposed on the first connecting seat 21. The limiting protrusion 611 can engage or disengage from the first limiting hole 212. Figure 3 and Figure 4 As shown, when the first locking member 31 (lock hook) is in the locked position, the limiting protrusion 611 is not engaged with the first limiting hole 212. During the downward movement of the first unlocking member 41, when the limiting protrusion 611 moves with the first unlocking member 41 to align with the first limiting hole 212, the second locking member 61 rotates at a certain angle to make the first limiting protrusion 611 engage with the first limiting hole 212, thereby locking the first unlocking mechanism and keeping the lock hook in the unlocked position. Figure 8 and Figure 9 As shown.

[0109] Further, see Figure 8 , Figure 12 and Figure 13 The first unlocking member 41 is provided with a second rotating shaft 414, and the second locking member 61 is provided with a rotating hole. The second rotating shaft 414 is inserted into the rotating hole and rotates with the rotating hole to realize the rotational connection between the second locking member 61 and the first unlocking member 41, so that the limiting protrusion 611 can be inserted into or released from the first limiting hole 212.

[0110] In other embodiments, the first limiting structure may also be an elastic hook provided on the second locking member 61, and the second limiting structure may be a locking hole provided on the first connecting seat 21. During the pressing down of the first unlocking member 41, the elastic hook can be engaged in the locking hole to limit the position of the first unlocking member and keep the locking hook in the unlocked position.

[0111] Optionally, see Figure 6 , Figure 7 , Figure 11 and Figure 12 The first unlocking component 41 of the first unlocking mechanism is provided with a second limiting hole 412. The limiting protrusion 611 is restricted by the second limiting hole 412 and can pass through the second limiting hole 412 and engage with the first limiting hole 212. Figure 3 , Figure 6 and Figure 7 As shown, when the locking hook is in the locked position, the limiting protrusion 611 is engaged within the second limiting hole 412 to prevent the second locking member 61 from swinging freely. Figure 8 , Figure 11 and Figure 12 As shown, after the first unlocking member 41 drives the lock hook to rotate to the unlock position, the limiting protrusion 611 passes through the second limiting hole 412 and is engaged in the first limiting hole 212 to restrict the first unlocking member 41 from moving in a preset direction, thereby keeping the lock hook in the unlock position.

[0112] Optionally, see Figure 3 and Figure 8The second locking mechanism 6 also includes a first elastic element 62. One end of the first elastic element 62 is connected to the second locking element 61, and the other end of the first elastic element 62 is connected to the first unlocking element 41. The second locking element 61 can be held in the locked position of the first unlocking mechanism under the elastic force of the first elastic element 62, ensuring that the first unlocking mechanism is securely locked. Specifically, as shown... Figure 3 As shown, when the first locking member 31 (lock hook) is in the locked position, the first elastic member 62 has a certain elastic potential energy, so that the limiting protrusion 611 of the second locking member 61 can be stably engaged with the second limiting hole 412, ensuring that the second locking member 61 does not swing arbitrarily. During the process of pressing down the first unlocking member 41, the second locking member 61 compresses the first elastic member 62 to deform and accumulate elastic potential energy. When the limiting protrusion 611 moves to align with the first limiting hole 212, the first elastic member 62 releases elastic potential energy to drive the second locking member 61 to rotate a certain angle. Then, the limiting protrusion 611 extends out of the second limiting hole 412 and engages in the first limiting hole 212. Under the elastic force of the first elastic member 62, the second locking member 61 is stably maintained in the position of locking the first unlocking member 41, so that the first locking member 31 is temporarily kept in the unlocked position.

[0113] In this embodiment, see Figure 3 and Figure 8 The second locking member 61 is provided with a positioning protrusion 613, which is coaxial with and opposite to the limiting protrusion 611. (See reference) Figure 3 and Figure 6 The first unlocking member 41 is provided with a positioning hole 413, and the first elastic member 62 is exemplarily a compression spring. One end of the compression spring is sleeved on the positioning protrusion 613, and the other end is restricted in the positioning hole 413, so that the first elastic member 62 can extend and retract stably.

[0114] Optionally, see Figure 2 and Figure 3 The second unlocking mechanism includes a second unlocking member 51 disposed on the second connecting seat 11. The second unlocking member 51 has a pushing part 511. During the process of the second connecting seat 11 disengaging from the first connecting seat 21, the pushing part 511 can push the second locking member 61 to rotate toward the position where the first unlocking mechanism is unlocked. That is, during the removal and installation of the vehicle body 2, while the second connecting seat 11 disengages from the insertion cavity 211 of the first connecting seat 21, the second unlocking member 51 drives the second locking member 61 to rotate, thereby releasing the restriction on the first unlocking member 41 and restoring the functions of the first unlocking mechanism and the first locking mechanism. This configuration eliminates the need for separately releasing the positional restriction of the first unlocking mechanism by the second locking mechanism 6, further improving the ease of disassembly and assembly of the vehicle body 2.

[0115] Further, see Figure 3 and Figure 13The pushing part 511 is provided with a third guide surface 5111, and the second locking member 61 is provided with a fourth guide surface 612. During the process of the second connecting seat 11 disengaging from the insertion cavity 211, the third guide surface 5111 and the fourth guide surface 612 slide in engagement. The first unlocking member 41 is then removed from... Figure 3 Pressed to the state shown Figure 8 After the indicated state is reached, the first locking element remains in the unlocked position. At this point, when the download device is removed, the second connecting seat 11 will disengage from the insertion cavity 211. Figure 8 Move to the state shown Figure 13 During the process shown, the third guide surface 5111 contacts and slides with the fourth guide surface 612. The third guide surface 5111 generates a pushing force on the fourth guide surface 612 to overcome the elastic force of the elastic member 62, causing the second locking member 61 to rotate counterclockwise until the limiting protrusion 611 on the second locking member 61 disengages from the first limiting hole 212 (as shown). Figure 13 (As shown), during this process, the elastic element 62 is compressed. See also... Figure 13 and Figure 15 As the second connecting seat 11 continues to disengage from the insertion cavity 211, the elastic element 62 releases elastic potential energy, driving the second locking element 61 to move the first unlocking element 41 upward to the initial position. Here, the initial position refers to the upper end of the first unlocking element 41 extending out of the opening 213 on the first connecting seat 21, and the stop step 415 on the first unlocking element 41 stopping at the edge of the opening 213.

[0116] The disassembly and assembly process of the base and body 2 of the child vehicle provided in this embodiment is roughly as follows:

[0117] like Figure 3 and Figure 4 As shown, assuming the initial state, the vehicle body 2 is locked to the base, and the locking hook of the first locking mechanism is engaged with the limiting block of the second connecting seat 11. When it is necessary to disassemble the vehicle body 2, the user presses the first unlocking member 41 of the first unlocking mechanism, causing the first unlocking member 41 to disengage from the base. Figure 3 Move to the position shown Figure 8 The position is shown. During this process, the second locking member 61 of the second locking mechanism 6 moves down with the first unlocking member 41 and compresses the elastic member 62. After the limiting protrusion 611 on the second locking member 61 aligns with the first limiting hole 212 on the first connecting seat 21, the limiting protrusion 611 is engaged in the first limiting hole 212 under the elastic force of the elastic member 62, thereby restricting the first unlocking member 41 to the current position and keeping the lock hook in the unlocked position, such as... Figure 9 and Figure 10 As shown. At this point, the user no longer needs to press the first unlocking component 41; they can simply remove the vehicle body 2 from the base with one or both hands.

[0118] like Figure 13 and Figure 14 As shown, during the process of removing the device body 2, the second connecting seat 11 disengages from the insertion cavity 211, and the pushing part 511 of the second unlocking member 51 drives the second locking member 61 to rotate counterclockwise until the limiting protrusion 611 on the second locking member 61 disengages from the first limiting hole 212. Figure 15 and Figure 16 As shown, during the process of the second connecting seat 11 continuing to disengage from the insertion cavity 211, the first elastic element 62 of the second locking mechanism 6 releases elastic potential energy to drive the second locking element 61 to move the first unlocking element 41 upward to the initial position. The force of the first guide surface 4111 of the first mating part 411 on the second guide surface 3111 of the second mating part 311 disappears, so that the lock hook automatically rotates back to the locking position clockwise under the elastic force of the elastic reset element.

[0119] When reassembling the loading device body 2 and the base, as follows: Figure 15 and Figure 16 As shown, the second connecting seat 11 is inserted into the insertion cavity 211. When the limiting block moves with the second connecting seat 11 to contact the locking hook, the second guide surface 121 contacts the first guide surface 312. As the second connecting seat 11 continues to be inserted into the insertion cavity 211, the second guide surface 121 slides with the first guide surface 312 to push the locking hook to rotate counterclockwise (the elastic reset member is compressed or stretched to store energy) until the second guide surface 121 disengages from the first guide surface 312 (as shown). Figure 14 As shown), when the limiting block continues to move upward with the second connecting seat 11, the locking hook will rotate clockwise under the elastic force of the elastic reset member until the locking hook catches the limiting block, and the vehicle body 2 is locked on the base.

[0120] Example 2

[0121] like Figures 17 to 22 As shown, this embodiment provides a child vehicle, which differs from Embodiment 1 in that:

[0122] Optionally, see Figure 17 and Figure 18 The first unlocking mechanism is connected to the first locking mechanism. When the first unlocking mechanism is operated, the first unlocking mechanism directly drives the first locking mechanism to move and unlock. In this embodiment, the first unlocking member 41 of the first unlocking mechanism is fixedly connected to the first locking member 31 of the first locking mechanism. The first unlocking member 41 can swing left and right relative to the first connecting seat 21 (see reference). Figure 17 and Figure 18 (The position in the middle), the user only needs to move the first unlocking component 41 to drive the first locking component 31 to unlock.

[0123] Furthermore, the first connecting seat 21 is provided with a insertion cavity 211, and the second connecting seat 11 can be inserted into or detached from the insertion cavity 211. The first locking member 31 is rotatably disposed within the insertion cavity 211. In this embodiment, the first locking member 31 is a locking hook, and the cooperating component 12 is a limiting block. When locked, the locking hook is engaged with the limiting block.

[0124] Optionally, the first limiting structure includes a locking pin 63 movably disposed in the first unlocking mechanism, and the second limiting structure includes a third limiting hole 214 disposed in the first connecting seat 21, wherein the locking pin 63 can engage or disengage from the third limiting hole 214. Figure 17 and Figure 18 As shown, when the first locking member 31 (lock hook) is in the locked position, the locking pin 63 is not engaged with the third limiting hole 214, and the first unlocking member 41 is facing towards... Figure 18 During the movement in the direction indicated by the arc-shaped arrow, when the locking pin 63 moves with the first unlocking member 41 to align with the third limiting hole 214, the locking pin 63 engages with the third limiting hole 214, thereby locking the first unlocking mechanism and keeping the first locking member 31 in the unlocked position. Figure 18 As shown.

[0125] Further, see Figure 17 and Figure 18 The second locking mechanism 6 also includes a second elastic element 64. One end of the second elastic element 64 is connected to the locking pin 63, and the other end of the second elastic element 64 is connected to the first unlocking mechanism. The locking pin 63 can be inserted into the third limiting hole 214 under the elastic force of the second elastic element 64, ensuring that the first unlocking mechanism is securely locked. Specifically, as shown... Figure 17 As shown, when the first locking member 31 is in the locked position, the end of the locking pin 63 abuts against the first connecting seat 21, and the second elastic member 64 is in a compressed state. When the first unlocking member 41 moves the locking pin 63 to align with the third limiting hole 214, the second elastic member 64 releases its elastic potential energy to drive the locking pin 63 into the third limiting hole 214. Under the elastic force of the second elastic member 64, the locking pin 63 is stably held in the position of locking the first unlocking member 41, so that the first locking member 31 is temporarily kept in the unlocked position.

[0126] In this embodiment, see Figure 17 The first unlocking member 41 is provided with a receiving cavity 416. The second elastic member 64 is exemplarily a compression spring. The compression spring is located inside the receiving cavity 416. One end of the spring is fixedly connected to the inner wall of the receiving cavity 416, and the other end is connected to the locking pin 63. The receiving cavity 416 can restrict the second elastic member 64 from driving the locking pin 63 to always move in a set direction, ensuring that the locking pin 63 can be accurately engaged in the third limiting hole 214.

[0127] Furthermore, the end of the locking pin 63 extending out of the receiving cavity 416 is designed as an arc surface to ensure that the locking pin 63 can smoothly engage or disengage from the third limiting hole 214.

[0128] In other alternative embodiments, the first limiting structure may also include an elastic hook disposed in the first unlocking mechanism, and the second limiting structure includes a third limiting hole 214 disposed in the first connecting seat 21. The elastic hook can engage with the third limiting hole 214 under its own elastic force. In the initial state, the hook portion of the elastic hook abuts against the outer wall of the first connecting seat 21 and has elastic potential energy. When the elastic hook moves with the first unlocking member 41 to align with the third limiting hole 214, the hook portion of the elastic hook engages with the third limiting hole 214 under its own elastic force, which can also lock the position of the first unlocking member 41 and keep the lock hook in the unlocked state.

[0129] Optionally, see Figure 17 and Figure 18 An elastic reset member 32 is provided between the locking hook and the inner wall of the insertion cavity 211. The locking hook can rotate towards the hook-locking block under the elastic force of the elastic reset member 32. During the unlocking process driven by the first unlocking member 41, the elastic reset member 32 is stretched. When the second connecting seat 11 disengages from the insertion cavity 211 and releases the first unlocking member 41, the elastic reset member 32 releases its elastic potential energy, causing the locking hook to rotate back towards the hook-locking block. The elastic reset member 32 enables the locking hook to automatically return to its original position, facilitating the next locking of the first connecting seat 21 and the second connecting seat 11.

[0130] In this embodiment, see Figure 18 The first locking member 31 is provided with a mounting cavity 311. One end of the elastic reset member 32 is located inside the mounting cavity 311, and the other end extends out of the mounting cavity 311 and connects to the inner wall of the insertion cavity 211, ensuring that the elastic reset member 32 can stably extend and retract. Exemplarily, the elastic reset member 32 is a tension spring. In other embodiments, if the elastic reset member 32 is located on the left side of the lock hook (refer to...), Figure 18 If the orientation is specified in the diagram, then the elastic reset element 32 can be a compression spring.

[0131] In other embodiments, an elastic arm can also be provided on the hook, with the end of the elastic arm away from the hook abutting against the inner wall of the insertion cavity 211. The hook can rotate towards the hook-locking block under the elastic force of the elastic arm. During the unlocking process where the first unlocking member 41 drives the hook to rotate and unlock, the elastic arm is compressed and undergoes elastic deformation. When the force exerted by the first unlocking member 31 on the hook decreases or disappears, the elastic arm releases elastic potential energy, thereby driving the hook to rotate in the opposite direction and return to its original position. For example, the elastic arm is an arc-shaped plate that extends out from the upper end of the hook, with the arc-shaped convex surface of the arc-shaped plate facing the hook portion of the hook. This ensures that the arc-shaped plate is compressed and accumulates elastic potential energy when the hook is unlocked.

[0132] Optionally, see Figure 17 and Figure 18The second unlocking mechanism includes a third unlocking member 52 disposed on the second connecting seat 11. During the process of the second connecting seat 11 disengaging from the first connecting seat 21, the third unlocking member 52 can drive the first locking mechanism to move towards the locking position, so that the first locking mechanism moves relative to the first connecting seat 21 and drives the locking pin 63 or the elastic hook to disengage from the third limiting hole 214. That is, during the process of removing and taking off the vehicle body 2, while the second connecting seat 11 disengages from the insertion cavity 211 of the first connecting seat 21, the third unlocking member 52 drives the first locking member 31 to rotate, so as to release the locking pin 63 from limiting the first unlocking member 41, so that the first unlocking mechanism and the first locking mechanism can restore their own functions. With this configuration, there is no need to separately release the position restriction of the second locking mechanism 6 on the first unlocking mechanism, further improving the ease of disassembly and assembly of the vehicle body 2.

[0133] In this embodiment, see Figure 18 and Figure 19 The third unlocking member 52 is a protrusion structure located on one side of the second connecting seat 11. The third unlocking member 52 has a pushing slope. During the process of the second connecting seat 11 disengaging from the insertion cavity 211, when the mating component 12 moves down with the second connecting seat 11 to avoid the hook portion of the first locking member 31 (lock hook), as the second connecting seat 11 continues to move down, the pushing slope contacts the first locking member 31 (e.g., ...). Figure 19 As shown), when the second connecting seat 11 continues to move, the pushing inclined surface pushes the first locking member 31 to rotate toward the mating part 12; at the same time, the first locking member 31 drives the first unlocking member 41 toward... Figure 19 The movement in the direction indicated by the arc-shaped arrow causes the locking pin 63 on the first unlocking component 41 to disengage from the third limiting hole 214 (as shown). Figure 19 and Figure 20 (As shown).

[0134] When reassembling the loading device body 2 and the base, as follows: Figure 21 and Figure 22 As shown, the second connecting seat 11 is inserted into the insertion cavity 211. When the mating component 12 moves with the second connecting seat 11 to contact the first locking component 31 (locking hook), the mating component 12 can push the locking hook to rotate clockwise until the mating component 12 disengages from the locking hook. At this time, if the second connecting seat 11 continues to move upward, the locking hook will rotate counterclockwise under the elastic force of the elastic reset component 32 until the locking hook catches the limiting block, and the carrier body 2 is locked on the base.
