Detailed Implementation

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] See Figures 1-5 This utility model provides a technical solution:

[0029] like Figures 1-5 As shown, a type B vehicle passageway fastening structure includes an inner folding canopy 1 and an outer folding canopy 2. The outermost rings of the inner folding canopy 1 and the outer folding canopy 2 are connected by a folding canopy frame 7. The folding canopy frame 7 is located near the outer folding canopy 2. The folding canopy frame 7 is connected to the vehicle body by a screw frame 3. One side of the screw frame 3 is fixed to the vehicle body, and the other side of the screw frame 3 is engaged with the folding canopy frame 7. A locking tongue 31 is provided between the folding canopy frame 7 and the screw frame 3.

[0030] The outermost ring of the inner folding canopy 1 is provided with hook and loop fasteners 4, and the vehicle body is provided with a connecting plate 5 corresponding to the position of the hook and loop fasteners 4. The connecting plate 5 is provided with felt 51 on the side facing the hook and loop fasteners 4, and the inner folding canopy 1 is connected to the vehicle body through the hook and loop fasteners 4 and the felt 51.

[0031] Through the above technical solution, the outer folding canopy 2 is connected to the vehicle body by inserting the screw frame 3 into the folding canopy frame 7 and then fixing it with the locking tongue 31; the inner folding canopy 1 is connected to the vehicle body by bonding and fixing it with the felt 51 using the hook and loop fastener 4, thus completing the overall connection of the passageway. Simultaneously, during the connection and disconnection process between the passageway and the vehicle body, simply rotate the locking tongue 31 to remove the folding canopy frame, and then forcefully separate the hook and loop fastener 4 from the felt 51. The entire passageway's fastening structure is simple, facilitating connection and disconnection. Furthermore, the hook and loop fastener 4 is positioned a distance from the inner folding canopy 1, allowing it to conceal the hook and loop fastener 4 and connecting plate 5 during vehicle operation, maintaining the aesthetics of the passageway.

[0032] The process of fixing the outer folding canopy 2 is as follows:

[0033] The two sides of the folding frame 7 are clamped and fixed to the outer rings of the inner folding frame 1 and the outer folding frame 2, respectively, connecting the inner folding frame 1 and the outer folding frame 2. Simultaneously, the outward protruding part of the folding frame 7 is a locking part 71. The locking part 71 is inserted into the locking groove 34 of the screw frame 3 to complete the locking. Then, the locking tongue 31 of the inner ring of the screw frame 3 is rotated. Since the locking tongue 31 includes a base 32 and a rotating rod 33, the base 32 is fixed to the inner ring of the screw frame 3, and the rotating rod 33 can rotate freely. By moving the rotating rod 33 into the locking groove 72 of the folding frame 7, the connection between the folding frame 7 and the screw frame 3 is completed.

[0034] The process of fixing the inner folding canopy is as follows:

[0035] Hook and loop fasteners 4 are installed around the outer ring of the inner folding canopy 1, and corresponding rings are also installed on the connecting plate 5 and the felt 51. The fasteners 4 are used to bond the felt 51 to the plate, effectively improving the bonding effect. The connecting plate 5 is fixed to the vehicle body with rivets and washers. The felt 51 is located between the connecting plate 5 and the washers, and is pressed onto the connecting plate 5 with screws and washers to prevent it from falling off, reducing the risk of the inner folding canopy 1 detaching from the vehicle body. The back of the felt 51 is also bonded to the connecting plate 5, further enhancing the connection effect.

[0036] Furthermore, each ring of the inner folding canopy 1 and the outer folding canopy 2 is arranged in an elliptical structure facing each other, and each ring between the inner folding canopy 1 and the outer folding canopy 2 is connected by a connecting clip 6, which is a U-shaped structure.

[0037] Through the above technical solution, the passageway where the inner folding canopy 1 and the outer folding canopy 2 are far apart can be connected and supported by the middle connecting clip 6. Each ring of the inner folding canopy 1 and the outer folding canopy 2 is provided with a connecting clip 6 at a different height to ensure the overall support effect of the inner folding canopy 1 and the outer folding canopy 2.

[0038] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
