[0051] Figure 1 is a schematic structural diagram of the roof storage component of an embodiment of the present utility model, asFigure 1 as shown and with reference to Figure 2 , an embodiment of the present utility model provides a roof storage assembly, which mainly consists of two parts: a platform assembly 100 and a functional module 200.

[0052] The platform assembly 100 includes a base member 110 for connecting to the roof, and an extension member 120 slidably connected to the base member 110 left and right; the extension member 120 is configured to extend from the left side and / or the right side of the base member 110 after being unfolded. As a preferred embodiment of the present utility model, the platform assembly 100 can use a frame assembly commonly found in existing commercially available roof storage device products. In a generally common frame-type platform assembly 100, the base member 110 may include two first longitudinal beams extending front and rear, and two first cross beams extending left and right are respectively bridged between the two ends of the two first longitudinal beams to enclose a square-shaped platform outer frame through the first longitudinal beams and the first cross beams, and several first slide trusses spaced front and rear are further provided inside the platform outer frame, and the slide trusses extend left and right; there are two extension members 120, and both extension members 120 include a second longitudinal beam extending front and rear and second cross beams extending left and right provided at both ends thereof, and a second slide truss connected to the second longitudinal beam and slidably engaged with the first slide truss is provided between the two second cross beams to enable the two extension members 120 to be slidably connected to the base member 110 relatively left and right, and when the distance between the two extension members 120 is the smallest, it basically falls within the range of the base member 110; and after the two extension members 120 are unfolded, the top surface area of the platform assembly 100 can be increased by 1.2 - 2 times.

[0053] A functional module 200 is also connected to the platform assembly 100 to realize the camping function of the roof storage assembly. The functional module 200 includes at least one of a side tent assembly 210, a top tent assembly 220, and a first ladder assembly 230a, wherein:

[0054] 1. The side tent assembly 210 includes a side tent framework 211, which is telescopically connected to the platform assembly 100 to extend from the side of the platform assembly 100 after being extended. The side tent referred to in the present utility model means a sky curtain located at the vehicle body side wall. Such side tent assemblies are common in commercially available products and all achieve deployment and storage through telescopic structures. For example, common sky curtain assemblies suspended on the vehicle side, sky curtain assemblies fixed to the vehicle body side wall using steel members, etc. The present utility model does not intend to provide a new type of side tent assembly in this embodiment, but rather lies in the combination of the side tent assembly and the new type of platform assembly 100, that is, to provide a roof storage assembly formed by at least combining a new type of platform assembly 100 (with an expansion member 120) and a side tent assembly 210. For example, the side tent assembly 210 is connected to the base member 110 of the platform assembly 100 or the expansion member 120 of the platform assembly 100. Especially when the side tent assembly 210 is connected to the expansion member 120, as the expansion member 120 is deployed from the base member 110, the side tent assembly 210 can be deployed at a position at a certain distance from the base member 110, that is, it extends the coverage area of the roof storage assembly on the ground. Even if the side tent assembly 210 is connected to the base member 110, it can form an overlapping relationship with the expansion member 120 in the vertical direction to protect the side tent assembly 210 and the expansion member 120.

[0055] 2. The top tent assembly 220 includes a top tent framework 221, and the top tent framework 221 is connected to the platform assembly 100; and the top tent framework 221 is configured to be fixed to the platform assembly 100 after being folded, and / or at least cover the base member 110 and the deployed expansion member 120 after being deployed.

[0056] As described in the above side tent assembly 210, in this embodiment of the present utility model, the specific structure of the top tent assembly 220 is not an essential technical solution after improvement, but mainly provides a top tent assembly 220 that can cover the deployed platform assembly 100. As for the composition of the top tent assembly 220, it can be an ordinary tent or a tent adapted to the roof rack product, such as an ordinary tent connected to the platform device in forms such as bundling and bolt connection. Thus, after the expansion member 120 of the platform assembly 100 is deployed, the top tent assembly 220 can be used to cover it, increasing the enclosed space available to the user on the vehicle roof.

[0057] 3. The first ladder assembly 230a is connected to the expansion member 120 to cause it to hang down from the protruding side of the expansion member 120 after the expansion member 120 is deployed.

[0058] As described in the side tent assembly 210 above, in this embodiment of the present utility model, the specific structure of the first ladder assembly 230a is not a new essential technical solution after improvement, but mainly provides a ladder connected to the expansion component 120. In this way, after the expansion component 120 is unfolded, the ladder can be unfolded from the expanded rear edge, so that the user can get on and off from the edge of the expanded platform assembly 100, facilitating the user to use the platform assembly 100. In addition, the first ladder assembly 230a unfolded from the vehicle body side wall allows the user to unfold the ladder from a closer distance inside the vehicle, facilitating the user to take shelter during travel and residence.

[0059] Based on the platform assembly 100 that uses the expansion component 120 to slide and expand on the base component 110, at least one of the top tent assembly 220, the side tent assembly 210, and the first ladder assembly 230a is adapted and modified so that at least one of the three can be adapted to the expansion component 120. Thus, on the platform assembly 100 with an enlarged usage area, at least one of the three can still be conveniently used, thereby improving the user experience.

[0060] As a preferred embodiment of the present utility model, as Figure 1 and Figure 2 shown, the top tent frame 221 has a first part and a second part. The first part is slidably connected to the base component 110 left and right and is rotatably connected to the base component 110 with left and right swinging. The second part is configured to be connected to the expansion component 120 after folding and to cover the base component 110 and the expansion component 120 after unfolding. The first part can be directly connected to the base component 110 (for example, connected to the first slide truss of the base component 110), or can be indirectly connected to the base component 110 through a slider component or a support component. In this way, when the top tent frame 221 adopts a fan-shaped folding structure, the top tent assembly 220 can cover the unfolded platform assembly 100 as large as possible.

[0061] As a preferred embodiment of the present utility model, the top tent framework 221 includes a top tent door frame 221a that opens to the left or right. The two end portions on the opening side of the top tent door frame 221a are slidably connected to the base member 110 in the left and right directions, and are rotatably connected to the base member 110 for left and right swinging; and / or, the abdomen of the top tent door frame 221a is configured to be connected to the expansion member 120 after folding, and to cover the base member 110 and the expansion member 120 after unfolding. When the top tent assembly 220 adopts a side opening (i.e., opening to the left or right), and is slidably and swingably connected to the base member 110, the top tent door frame 221a can be fan-shapedly unfolded and fan-shapedly folded in the left and right directions. In this way, not only can the top tent assembly 220 cover a larger area after the expansion member 120 is unfolded, but also the top tent assembly 220 can be folded within the range of the platform assembly 100 after the expansion member 120 is retracted; at the same time, for a tent that opens to the left or right, a larger interior space of the tent can also be obtained.

[0062] As a preferred embodiment of the present utility model, there are two of the expansion members 120, and the two are distributed relatively left and right on the base member 110; and, when the functional module 200 at least includes the top tent assembly 220, the abdomen of the top tent door frame 221a of the top tent assembly 220 is connected to one of the two, and the opening side of the top tent door frame 221a extends from the side of the one close to the other and is connected to the base member 110. To adapt to the advantages that the two expansion members 120 extend from both sides of the base member 110 more safely and have a larger expansion area, adapting the top tent assembly 220 will be more beneficial to improving the user experience. Especially when the top tent assembly 220 uses a folding fan type, for the top tent door frame 221a to adapt to the case of double expansion members 120, the top tent door frame 221a is connected to the base member 110 by sliding and rotating at one end and is connected to the expansion member 120 at the other end. In this way, on the basis of ensuring that the top tent framework 221 can be folded into the platform assembly 100, the maximum coverage area of the top tent component can be achieved.

[0063] As a preferred embodiment of the present utility model, when the functional module 200 further at least includes a first ladder assembly 230a, there is at least one ladder assembly, and it is connected to the other of the two expansion members 120 to cause it to hang down from the opening side of the top tent door frame 221a. In this way, the first ladder assembly 230a can be unfolded from the opening side of the top tent assembly 220, facilitating the user to climb up and down from the opening side of the top tent assembly 220, and further improving the user experience.

[0064] As another preferred embodiment of the present utility model, as Figure 3 and Figure 4, there are two expansion components 120, and the two are distributed relatively left and right on the base component 110; and, when the function module 200 at least includes the top tent component 220, the top tent frame 221 of the top tent component 220 includes a top tent side frame 221b and a top tent top frame 221c. There are two top tent side frames 221b, and the two are respectively swing-connected front and back to the mutually remote sides of the two expansion components 120; the top tent top frame 221c is bridged between the free ends of the two top tent side frames 221b, and it can be telescoped and / or bent and / or folded in the left-right direction, so as to cause, after the top tent frame 221 is folded, it and the two top tent side frames 221b enclose a U-shaped opening backward. Compared with the side-opening top tent component 220, this rear-opening top tent component 220 can meet the user's need to enter and exit the tent from the rear of the vehicle, and at the same time meet the user's need to have a larger interior space of the tent on the roof of the vehicle.

[0065] As a preferred embodiment of the present invention, when the function module 200 further at least includes a second ladder assembly 230b, the second ladder assembly 230b is connected to the platform assembly 100, and is configured to extend and hang from the rear side of the platform assembly 100. The setting of the second ladder assembly 230b can meet the user's need to get on and off the platform assembly 100 from the rear of the vehicle.

[0066] As a preferred embodiment of the present invention, the base component 110 defines a receiving cavity located below the expansion component 120, and the receiving cavity opens backward; and, the second ladder assembly 230b is located in the receiving cavity, and is configured to extend backward from the opening of the receiving cavity. Based on the up-and-down layout of the expansion component 120 and the base component 110, that is, when the expansion component 120 is located above the base component 110, the internal space of the base component 110 is used as a receiving space for storing items, and the second ladder assembly 230b is stored therein. On the one hand, it is convenient to store the second ladder assembly 230b on the vehicle and reduces the occupation of the effective storage space in the vehicle; on the other hand, it is also convenient for the deployment of the second ladder assembly 230b.

[0067] As a preferred embodiment of the present invention, when the function module 200 further at least includes side tent assemblies 210, there are two side tent assemblies 210, and the two are respectively connected to the mutually remote sides of the two expansion components 120. Since the user can get on and off the roof of the vehicle from the rear of the vehicle and enter and exit the unfolded top tent component 220, side tent assemblies 210 can be provided on the left and right expansion components 120, and the tent coverage area can be further reasonably increased.

[0068] As a preferred embodiment of the present utility model, when the functional module 200 includes at least the side tent assembly 210, there are three side tent assemblies 210, and the three are respectively located on the left side, right side and rear side of the platform assembly 100; or, there are four side tent assemblies 210, and the four are respectively located on the front side, rear side, left side and right side of the platform assembly 100. Compared with the case where the side tent assembly 210 is deployed from both the left and right sides of the platform assembly 100, without limiting the connection position of the side tent assembly 210 (for example, the side tent assembly 210 can be connected to the extension member 120, or can be connected to the base member 110, or a part can be connected to the extension member 120 and the other part can be connected to the base member 110), the number of the side tent assemblies 210 can be three or four to further increase the side tent space, so that the user can obtain a larger space inside the tent.

[0069] As a preferred embodiment of the present utility model, the base member 110 defines a receiving cavity located below the extension member 120 and a platform opening located on the extending side of the extension member 120; and, when the functional module 200 includes at least the ladder assembly, before the extension member 120 is deployed, the first ladder assembly 230a is in the receiving cavity. The first ladder assembly 230a can also be arranged in the receiving space of the base member 110 to save the storage space of the vehicle.

[0070] As a preferred embodiment of the present utility model, the top tent assembly 220 further includes a top tent cloth 222 and a storage bag cloth (not shown in the figure). The top tent cloth 222 is connected to the top tent frame 221 to urge it to cover the deployed top tent frame 221; the storage bag cloth is connected to the platform assembly 100 and / or connected to the top tent cloth 222 to urge it to store the folded top tent frame 221 and the top tent cloth 222. Using the storage bag cloth to store the top tent cloth 222 and the top tent frame 221 can reduce the weight on the one hand and save space on the other hand.

[0071] As a preferred embodiment of the present utility model, the side tent assembly 210 further includes a rolling curtain mechanism 212 and a side tent cloth 213. The rolling curtain mechanism 212 is connected to the base member 110 or the extension member 120; one end of the side tent cloth 213 is wound and connected to the rolling curtain mechanism 212, and the other end is connected to the side tent frame 211. In this embodiment, the rolling curtain mechanism 212 controls the deployment and folding of the side tent cloth 213, so that functions such as pulling and stopping immediately, automatic retracting, and even automatic deployment can be realized.

[0072] As another preferred embodiment of this embodiment, the base member 110 defines a receiving cavity located on the lower side of the extension member 120 and a platform opening located on the protruding side of the extension member 120; and, the functional module 200 further includes at least one of a photovoltaic panel and an escape board. Among them, the photovoltaic panel is movably disposed in the receiving cavity and is configured to be loaded into and taken out from the platform opening of the base member 110; the escape board is movably disposed in the receiving cavity and is configured to be loaded into and taken out from the platform opening of the base member 110. To make full use of the receiving cavity in the base member 110, a photovoltaic panel and / or an escape board can also be added to the receiving cavity to expand the receiving function and further improve the versatility of the roof storage assembly of the present utility model. In particular, the photovoltaic panel can be independent of the platform assembly 100 or connected to the platform assembly 100.
