[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, the connection structure of this embodiment includes a first component 1 and a second component 2, which are rotatably connected.

[0019] The connecting structure also includes a locking mechanism disposed between the first component 1 and the second component 2 to lock their relative positions. The locking mechanism has a locked state and an unlocked state. When the locking mechanism is in the locked state, the first component 1 and the second component 2 are fixed relative to each other and cannot rotate relative to each other. When the locking mechanism is in the unlocked state, the first component 1 and the second component 2 can rotate relative to each other.

[0020] like Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, the locking mechanism includes a locking member 3 that is slidably disposed between the first component 1 and the second component 2. When the locking mechanism is in the locked state, the locking member 3 cooperates with the first component 1 and the second component 2 respectively. Figure 1 , Figure 3 , Figure 4 and Figure 8As shown. When the locking mechanism is in the unlocked state, one of the first component 1 and the second component 2 engages with the locking element 3, while the other disengages from the locking element 3, as shown. Figure 6 As shown.

[0021] In this embodiment, such as Figure 1 As shown, locking components 3 are provided with locking teeth 31, the first component 1 is provided with a first tooth groove 11, and the second component 2 is provided with a second tooth groove. When the locking mechanism is in the locked state, the locking teeth 31 are engaged with the first tooth groove 11 and the second tooth groove respectively. When the locking mechanism is in the unlocked state, one of the first tooth groove 11 and the second tooth groove is engaged with the locking teeth 31, and the other is disengaged from the locking teeth 31.

[0022] The connection structure also includes an unlocking mechanism, which, when the locking mechanism is in the locked state, drives the locking mechanism to unlock from the locked state by operating the unlocking mechanism.

[0023] like Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, the unlocking mechanism includes an unlocking member 4 movably disposed on the first component 1 or the second component 2. The unlocking member 4 cooperates with the locking member 3, so that when the locking mechanism is in the locked state, the unlocking member 4 is driven to move relative to the first component 1 or the second component 2, thereby driving the locking member 3 to slide in the first direction, thereby unlocking the locking mechanism.

[0024] The unlocking mechanism may also include an operating element (not shown in the figure) that is actively set and a linkage element (not shown in the figure) disposed between the operating element and the unlocking element 4. When the locking mechanism is unlocked, the operating element is operated, which drives the unlocking element 4 to move through the linkage element, thereby causing the locking element 3 to slide and unlocking the locking mechanism.

[0025] like Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, the connecting structure may further include a first elastic element 5, which is used to drive the locking mechanism to lock from the unlocked state. The first elastic element 5 is disposed between one of the first component 1 and the second component 2 and the locking component 3 to drive the locking component 3 to slide in a second direction, which is opposite to the second direction.

[0026] like Figures 1-8 As shown, the connection structure also includes a display element 6, which is movably disposed on the first component 1 or the second component 2, and is used to display the status of the locking mechanism.

[0027] Specifically, the display element 6 has a first position and a second position. When the locking mechanism is in the locked state, the display element 6 is in the first position, such as... Figures 2-4 , Figure 7 and Figure 8 As shown. When the locking mechanism is in the unlocked state, the display 6 is in the second position, as shown. Figure 5 and Figure 6 As shown. In this way, the state of the locking mechanism can be intuitively judged by the position change of the display 6, thereby ensuring that the locking mechanism remains locked during the use of the vehicle, thus improving the safety performance of the vehicle.

[0028] Specifically, such as Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, a receiving cavity 221 is provided on the first component 1 or the second component 2, and the display component 6 is movably disposed in the receiving cavity 221. One end of the receiving cavity 221 is provided with an opening for the display component 6 to enter and exit the receiving cavity 221, and the display component 6 can enter and exit the receiving cavity 221 through the opening.

[0029] In this embodiment, when the display element 6 is in the first position, the display element 6 is entirely located within the receiving cavity 221, and the outer end face of the display element 6 is flush with the outer end face of the receiving cavity 221, or the outer end face of the display element 6 is located inside the outer end face of the receiving cavity 221, such as... Figure 3 , Figure 4 and Figure 8 As shown. When the display element 6 is in the second position, the display element 6 extends at least partially outside the receiving cavity 221, and the outer end face of the display element 6 is located outside the outer end face of the receiving cavity 221, as shown. Figure 6 As shown.

[0030] Alternatively, in other embodiments, when the display element 6 is in the first position, the outer end face of the display element 6 may be located outside the outer end face of the receiving cavity 221, or the outer end face of the display element 6 may be flush with the outer end face of the receiving cavity 221. When the display element 6 is in the second position, the display element 6 is entirely located inside the receiving cavity 221, and the outer end face of the display element 6 is located inside the outer end face of the receiving cavity 221.

[0031] This arrangement of the display element 6 position makes it easier to identify changes in its position, thereby accurately determining the status of the locking mechanism.

[0032] The display element 6 includes a display portion 61. In this embodiment, when the display element 6 is in the first position, the display portion 61 is entirely housed within the receiving cavity 221. When the display element 6 is in the second position, most of the display portion 61 extends outside the receiving cavity 221.

[0033] In this embodiment, the display element 6 is slidably disposed on the first component 1 or the second component 2, and the display element 6 can be switched between the first position and the second position by sliding the display element 6 relative to the first component 1 or the second component 2.

[0034] In one embodiment, the locking element 3 or the unlocking element 4 is connected to the display element 6, so that when the locking element 3 or the unlocking element 4 slides, it drives the display element 6 to move synchronously.

[0035] The display component 61 also includes a connecting part 62, one end of which is fixedly connected to or integrally formed with the display unit 61. The connecting part 62 is fixedly connected to the locking component 3 or the unlocking component 4.

[0036] Specifically, such as Figure 4 As shown, the connecting part 62 is connected to the locking member 3, and the unlocking member 4 and the display member 6 are respectively disposed on opposite sides of the locking member 3. The connection between the connecting part 62 and the locking member 3 is as follows: the locking member 3 is provided with a slot 32, and the end of the connecting part 62 away from the display member 61 is provided with a hook 621, which engages with the slot 32. In this embodiment, the connecting part 62 can undergo a certain degree of elastic deformation, so that the hook 621 engages with the slot 32 during installation.

[0037] In other embodiments, the locking element 3 or the unlocking element 4 may also cooperate with the display element 6.

[0038] Specifically, when the locking member 3 is driven to move in the second direction under the elastic force of the first elastic member 5, so that the locking mechanism is locked from the unlocked state, the locking member 3 or the unlocking member 4 cooperates with the display member 6, thereby driving the display member 6 to move from the second position to the first position.

[0039] In other embodiments, when the display 6 is in the second position and the display portion 61 is outside the receiving cavity 221, the first elastic member 5 may not be provided. When the locking mechanism needs to lock, a force can be applied to the display portion 61 to move the display portion 61 toward the direction closer to the opening, thereby driving the locking member 3 to move, so that the locking mechanism locks.

[0040] The connecting structure also includes a second elastic element (not shown in the figure), which is disposed between the first component 1 or the second component 2 and the display component 6. When the locking component 3 is moved in the first direction by the unlocking component 4 to unlock the locking mechanism from the locked state, the elastic force of the second elastic element drives the display component 6 to move from the first position to the second position. The elastic force of the first elastic element 5 must be greater than the elastic force of the second elastic element. In other embodiments, the second elastic element may not be provided, and the movement of the display component 6 may be driven by the movement of the locking component 3 or the unlocking component 4.

[0041] In this embodiment, the first component 1 and the second component 2 are rotatably connected by a rotating shaft 7. The locking component 3 and the unlocking component 4 are both sleeved on the rotating shaft 7 and can be slidably disposed along the axial direction of the rotating shaft 7. The display component 6 can be slidably disposed in the axial extension direction of the rotating shaft 7. This arrangement makes the connection structure simple and compact, and facilitates the processing and manufacturing of the connection structure.

[0042] The connecting structure has an unfolded state and a folded state. When the connecting structure is in the unfolded state and / or folded state, the locking mechanism is in the locked state, and the display 6 is in the first position. This connecting structure can be applied to a vehicle, such as a stroller. The connecting structure can be located at the connection between the upper push rod 81 and the lower push rod 82. One of the first component 1 and the second component 2 is fixedly connected to the upper push rod 81, and the other is fixedly connected to the lower push rod 82.

[0043] A canopy rod 83 can also be provided at the connection between the upper push rod 81 and the lower push rod 82. The second component 2 includes a push rod connecting seat 21 and a canopy rod connecting seat 22 rotatably connected to the push rod connecting seat 21. Preferably, the first component 1, the push rod connecting seat 21, and the canopy rod connecting seat 22 are coaxially rotatably connected by a rotating shaft 7. One of the first component 1 and the push rod connecting seat 21 is fixedly connected to the upper push rod 81, and the other is fixedly connected to the lower push rod 82. The first component 1, the push rod connecting seat 21, and the canopy rod connecting seat 22 are arranged sequentially along the axial direction of the rotating shaft 7. The receiving cavity 221 is located on the outermost component, that is, the display element 6 is located on the outermost component among the first component 1, the push rod connecting seat 21, and the canopy rod connecting seat 22, so as to facilitate observation of the position of the display element 6.

[0044] When the stroller is in both the unfolded and folded states, the locking mechanism is locked, and the display element 6 is in the first position. Figures 2-4 , Figure 7 and Figure 8 As shown. During the unfolding and folding of the stroller, the locking mechanism is always unlocked, and the display element 6 is in the second position, as indicated. Figure 5 and Figure 6 As shown.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
