With continued reference to fig. 4 to 6, a protrusion 413 and a recess 420 are provided between the locking member 41 and the locking base 42, which are engaged with each other, so as to perform a sliding guiding function, thereby enabling the locking member 41 to move more smoothly. The middle frame 3 is also provided with a guide rod 32 for guiding the locking member 41 to move up and down, and the locking member 41 and the guide rod 32 are in sliding fit. In this embodiment, the middle frame 3 includes a hollow upright 31, the guide bar 32 is located in the upright 31 and fixed on the locking base 42, and the upright 31 is provided with an opening 310, so that a portion of the locking member 41 can be inserted into the opening 310 to slide in cooperation with the guide bar 32. In this embodiment, the locking member 41 is provided with a guide slider 412 protruding into the opening 310, and a semicircular notch matched with the guide rod 32 is provided in the middle of the guide slider 412, so that the locking member 41 can slide up and down along the guide rod 32.

With continued reference to fig. 4 to 6 and fig. 8 and 9, the locking portion 411 is configured as a hook, and the first frame 1 and the second frame 2 are configured with fastening shafts 11 and 21 adapted to the hook. The opening of the hook faces in the direction that the locking member 41 is biased by the biasing member 43, and in this embodiment, the locking member 41 is biased downward by the biasing member 43, and the opening of the hook faces downward. In this embodiment, the free ends of the clamping shafts 11 and 21 are further provided with shaft caps to block the locking portions 411 clamped on the clamping shafts 11 and 21 in the axial direction, so as to prevent the locking portions 411 from being separated from the clamping shafts 11 and 21 in the axial direction, and the connection state is more reliable.

In this embodiment, the upper and lower sides of the middle frame 3 are respectively provided with a locking device 4, and the guide rod 32 is connected between the upper and lower locking devices 4. In the present embodiment, the locking devices 4 are configured as two sets of locking devices 4 disposed opposite to each other in the frame width direction, wherein each set of locking devices 4 includes two locking devices 4 disposed on the upper and lower sides of the middle frame 3, respectively, i.e., 4 locking devices 4 are disposed.

Example two

Referring to fig. 10-12, another embodiment of a foldable frame 100 of the present application is shown. In this embodiment, the structure of the locking device 4 is different from that of the first embodiment. In this embodiment, the locking device 4 comprises a locking member 41 configured to be rotatable about an axis. As shown in fig. 11, the middle frame 3 is provided with a locking base 42 fitted with the locking member 41, the locking base 42 is fixed to the middle frame 3, the locking member 41 is pivotally connected to the locking base 42, the locking member 41 has a rotation shaft portion 415, and the locking member 41 is rotatable about an axis of the rotation shaft portion 415. Similarly to the embodiment, a biasing member is arranged between the lock member 41 and the lock base 42, the biasing member being arranged to bias the lock member 42 in a direction to hold the lock. In this embodiment, the locking portion 411 is configured as a hook, and the first frame 1 and the second frame 2 are configured with a slot adapted to the hook. Referring to fig. 10, the first frame 1 and the second frame 2 are provided with a clamping strip 12, and the clamping strip 12 is formed with a slot for adapting to the locking portion 411 configured as a hook. In this embodiment, the clamping strip 12 is fixedly mounted on the first frame 1 and the second frame 2 to form the clamping groove; in other embodiments, the clamping groove may be directly formed on the first frame 1 or the second frame 2. In this embodiment, the locking devices 4 are configured as two sets of locking devices disposed opposite to each other in the width direction of the frame, wherein each set of locking devices 4 includes two locking devices disposed on the left and right sides of the middle frame 3. In this embodiment, the frame is configured to have the shape of a luggage or a tool box in a folded state.

The first and second leaves in the first side hinge 512 are pivotally connected by a central pin. When the folding type folding device is folded, the pin shaft part moves towards the inner side of the storage cavity, the first page plate rotates around the pin shaft line arranged on the first frame 1 to realize the inner side overturning of the first storage cavity, and the second page plate rotates around the pin shaft line arranged on the middle frame 3 to realize the inner side overturning of the first storage cavity. The structure realizes the overturning and folding of the side hinge towards the inner side of the storage cavity.

The first folding assembly 51 further includes a first bottom hinge 511 extending along the length direction, and the first bottom hinge 511 includes a third leaf and a fourth leaf pivotally connected to each other; wherein the third leaf is pivotally connected to the first rim 1 and the fourth leaf is pivotally connected to the middle frame 3. The third and fourth leaf are pivotally connected by a pin, and the third leaf is pivotally connected to the first rim 1 by another pin, and the fourth leaf is pivotally connected to the middle frame 3 by a pin. When folding is carried out, the third page plate turns over towards the inner side of the first storage cavity relative to the first frame 1, and the fourth page plate turns over towards the inner side of the first storage cavity relative to the middle frame 3.

In order to facilitate assembly and reduce the structural cost, the first folding assembly 51 and the second folding assembly 52 are symmetrically disposed with respect to the middle frame 3 in this embodiment, and are of substantially identical structural configuration, as shown in fig. 1-3. That is, the second folding assembly 52 is identical to the first folding assembly 51, and includes a pair of side hinges and a bottom hinge, and the side hinges and the bottom hinge are folded inward. The structure of the second folding assembly 52 can be understood by referring to the first folding assembly 51, and will not be described herein. It should be noted that the specific embodiment of the folding assembly described above is only one embodiment, but not all embodiments, for achieving the object of the present patent, and is not intended to limit the scope of protection of the present patent solely.

In addition, the application also provides a foldable camping vehicle, which comprises the foldable frame.
