[0052] Figure 1 is a schematic top view of a vehicle-mounted platform according to an embodiment of the present application, asFigure 1 The utility model discloses an extendable vehicle-mounted platform, which comprises a fixed platform 100, a first platform 200, a second platform 300, a roller assembly and a slide rail. Figures 2 to 5 The utility model discloses an extendable vehicle-mounted platform, which comprises a fixed platform 100, a first platform 200, a second platform 300, a roller assembly and a slide rail.

The plurality of first transverse frame rods 210 are arranged in parallel and at intervals along the front-rear direction. The first platform 200 is configured to be slidable towards the left side relative to the fixed platform 100.

[0055] The second platform 300 comprises a plurality of second transverse frame rods 310 extending along the left-right direction. The plurality of second transverse frame rods 310 are arranged in parallel and at intervals along the front-rear direction. The second platform 300 is configured to be slidable towards the right side relative to the fixed platform 100.

[0056] The roller assembly comprises rollers 410 arranged vertically and fixing members 420 fixedly connected to the front side and / or the rear side of the first transverse frame rods 210 and the front side and / or the rear side of the second transverse frame rods 310. The rotating shafts of the rollers 410 are integrally formed with the fixing members 420.

[0057] The slide rail extends along the left-right direction, is fixedly connected to the fixed platform 100, and is rollingly connected to the rollers 410.

[0058] In the embodiment, the first platform 200 and the second platform 300 are both movable relative to the fixed platform 100, so as to expand the overall storage area of the vehicle-mounted platform, and the upper side of the vehicle-mounted platform can be arranged with large-volume articles such as a tent, thereby improving the space utilization rate of the roof of the vehicle. Moreover, the first platform 200 and the second platform 300 can be retracted during the driving of the vehicle, so as to avoid large wind resistance during driving, thereby reducing the wind noise generated by the vehicle-mounted platform and improving the user experience.

[0059] The first platform 200 and the second platform 300 are moved in the left-right direction through the rolling of the rollers 410 fixedly connected thereto. The rollers 410 are arranged vertically on the front side and / or the rear side of the first transverse frame rods 210 and the front side and / or the rear side of the second transverse frame rods 310, so that the rollers 410 can also provide upward supporting force for the first platform 200 and the second platform 300, thereby improving the stability of the first platform 200 and the second platform 300. The rollers 410 are rollingly connected to the slide rail in the left-right direction, so that when the rollers 410 are subjected to downward extrusion radial force, the rollers 410 still have small frictional force during rolling, the rollers 410 are not prone to damage, and the service life of the rollers 410 is improved.

[0060] In some embodiments of the utility model, as shown in Figure 4 The fixing platform 100 includes a plurality of third transverse frame rods 110 extending along the left-right direction. The plurality of third transverse frame rods 110 are arranged in parallel and at intervals along the front-rear direction.

[0061] The first transverse frame rods 210 and the second transverse frame rods 310 are arranged one by one in correspondence, and the corresponding first transverse frame rods 210 and second transverse frame rods 310 coincide in the front-rear direction. The third transverse frame rods 110 and the first transverse frame rods 210 are arranged alternately in the front-rear direction.

[0062] In this embodiment, the first platform 200 and the second platform 300 can move relative to the fixing platform 100. The third transverse frame rods 110 and the first transverse frame rods 210 are arranged alternately in the front-rear direction, that is, the third transverse frame rods 110 and the second transverse frame rods 310 are arranged alternately in the front-rear direction, so that the fixing of the first platform 200 and the second platform 300 is more firm, and the carrying capacity of the first platform 200 and the second platform 300 is improved.

[0063] In some embodiments of the utility model, the first transverse frame rods 210 and the second transverse frame rods 310 are arranged alternately in the front-rear direction.

[0064] In this embodiment, the first platform 200 and the second platform 300 can move relative to the fixing platform 100. The structure of the first transverse frame rods 210 and the second transverse frame rods 310 arranged alternately in the front-rear direction is relatively simple, which is convenient for manufacturing and maintenance, and reduces the manufacturing and maintenance cost of the vehicle-mounted platform. Moreover, the first transverse frame rods 210 and the second transverse frame rods 310 arranged alternately in the front-rear direction make the length of the first transverse frame rods 210 and the second transverse frame rods 310 in the left-right direction longer, so that the part of the first platform 200 and the second platform 300 pulled out to the outside is more, and the overall storage area of the vehicle-mounted platform is further expanded.

[0065] In some embodiments of the utility model, the vehicle-mounted platform further includes a plurality of first connecting columns 600, the first connecting columns 600 extend along the front-rear direction, and the first connecting columns 600 are fixedly connected to the lower side of the fixing platform 100. The plurality of first connecting columns 600 are arranged at intervals along the left-right direction to form storage compartments 620 between every two adjacent first connecting columns 600.

[0066] In this embodiment, the plurality of spaced-apart storage compartments 620 can place different articles in different storage compartments 620, and the storage compartments 620 can be designed according to the size of the articles to be placed, so as to avoid the articles placed in the storage compartments 620 from shaking violently during the driving of the vehicle, and even causing scratching and knocking with the side walls of the storage compartments 620.

[0067] In some embodiments of the utility model, the vehicle-mounted platform further comprises two longitudinal beams 610, two cross beams 800 and a cross rod 900 extending along the left-right direction.

[0068] The two longitudinal beams 610 extend along the front-back direction, and are fixedly connected to the left end of the first transverse frame rod 210 and the right end of the second transverse frame rod 310 respectively; a storage compartment 620 is formed between the two longitudinal beams 610;

[0069] The cross beams 800 extend along the left-right direction and are arranged at intervals in the front-back direction to define the front and back ends of the storage compartment 620; the two longitudinal beams 610 and the two cross beams 800 are arranged alternately to surround the four sides of the storage compartment 620;

[0070] The cross rod 900 and the fixed platform 100 are arranged at intervals in the up-down direction, and the storage compartment 620 is between the cross rod 900 and the fixed platform 100.

[0071] In this embodiment, the vehicle-mounted platform is provided with the storage compartment 620 for storing escape boards, mattresses and other vehicle-mounted items, thereby improving the space utilization of the vehicle-mounted platform, making the vehicle-mounted platform have a wider range of uses, and further improving the user experience.

[0072] In some embodiments of the utility model, as shown in Figure 2 The vehicle-mounted platform further comprises purlins extending front-back, and the purlins are connected to the lower side of the left end and / or the right end of the plurality of third transverse frame rods 110.

[0073] In this embodiment, the purlins are fixedly connected to the lower side of the third transverse frame rods 110, so that the third transverse frame rods 110 and the purlins are connected perpendicularly and cross each other, thereby improving the structural strength of the fixed platform 100.

[0074] In some embodiments of the utility model, a support seat is connected between the purlin and the cross rod 900.

[0075] Preferably, the support seat is U-shaped, and the opening of the support seat faces the inner side of the fixed platform 100.

[0076] In this embodiment, the support seat is designed in a U shape, which can not only increase the spacing between the purlin and the cross rod 900, so that the purlin receives a buffering force from the support seat when subjected to force, but also saves the amount of material used for the support seat and reduces the production cost of the support seat.

[0077] In some embodiments of the utility model, the vehicle-mounted platform further comprises two slide rods 810 extending along the left-right direction, and the two slide rods 810 are arranged at intervals in the front-back direction; the two slide rods 810 are fixedly connected to the front and back ends of any longitudinal beam 610 respectively, and each slide rod 810 is slidingly connected to the inside of a cross beam 800, so that the longitudinal beam 610 can slide along the left-right direction.

[0078] In the embodiment, the longitudinal beams 610 are moved in the left-right direction by the sliding connection of the slide rods 810 and the cross beams 800 to slide the first platform 200 or the second platform 300. The structure of the slide rods 810 and the cross beams 800 is simple, facilitating the design and manufacturing, reducing the design and manufacturing cost of the vehicle-mounted platform, and improving the stability of the first platform 200 or the second platform 300 after being unfolded.

[0079] Moreover, the longitudinal beams 610 can be opened or closed by the sliding connection of the slide rods 810 and the cross beams 800 to open the opening of the storage compartment 620 at the cross beam 800. The structure of the slide rods 810 and the cross beams 800 is simple, facilitating the design and manufacturing, reducing the design and manufacturing cost of the vehicle-mounted platform.

[0080] In some embodiments of the utility model, as shown in Figure 1 The vehicle-mounted platform further comprises side tent poles 700 and tent cloth.

[0081] The side tent poles 700 are arranged at the side of the longitudinal beams 610 away from the other longitudinal beams 610 in the left-right direction. The side tent poles 700 are configured to be movable relative to the fixed platform 100 in the left-right direction.

[0082] The tent cloth is between the longitudinal beams 610 and the side tent poles 700 close to the side tent poles 700, and the two ends of the tent cloth are connected to the longitudinal beams 610 and the side tent poles 700 respectively to drive the tent cloth to stretch or retract when the side tent poles 700 are moved.

[0083] In the case that the storage compartments 620 are formed between every two adjacent first connecting columns 600, each longitudinal beam 610 corresponds to a first connecting column 600.

[0084] In the embodiment, the vehicle-mounted platform further has a side tent formed by the tent cloth to shield sunlight and rain. When the tent cloth needs to be used, the side tent poles 700 are moved towards the direction away from the longitudinal beams 610 to unfold the tent cloth between the side tent poles 700 and the longitudinal beams 610. When the tent cloth does not need to be used or during the driving of the vehicle, the side tent poles 700 are at the side of the longitudinal beams 610 so that the tent cloth is stored, avoiding excessive wind resistance of the tent cloth during the driving of the vehicle, reducing the overall width of the vehicle-mounted platform, avoiding the vehicle-mounted platform from being bumped during the driving of the vehicle, and improving the user experience.

[0085] The side tent poles 700 are arranged at the side of the longitudinal beams 610, that is, the side tent poles 700 and the longitudinal beams 610 of the vehicle-mounted platform are independent structures. After the side tent assembly is unfolded, the longitudinal beams 610 do not need to be separated from the original vehicle-mounted platform, avoiding the situation that one side of the cross beams 800 is suspended, improving the bearing effect of the vehicle-mounted platform, reducing the failure rate of the vehicle-mounted platform, and improving the user experience.

[0086] In some embodiments of the utility model, as shown in Figure 2 The side pole 700 is a hollow structure extending in the front-rear direction, and a horizontal plate 710 is connected between the left and right side walls of the side pole 700, so that a connecting groove 720 is formed in the inside of the side pole 700 at the upper end and / or the lower end of the horizontal plate 710.

[0087] The vehicle-mounted platform further comprises a connecting piece 730 and a telescopic rod 500. The connecting piece 730 is located at the front end or the rear end of the side pole 700 and is inserted into the front end or the rear end of the connecting groove 720.

[0088] The two ends of the telescopic rod 500 are connected to the connecting piece 730 and the fixed platform 100, respectively.

[0089] In this embodiment, since the side pole 700 is a hollow structure, the overall weight of the vehicle-mounted platform is reduced, and the energy consumption of the vehicle is lowered. However, the hollow structure has poor structural strength. In the utility model, the horizontal plate 710 is designed so that the left and right sides of the horizontal plate 710 are connected to the left and right side walls of the side pole 700, respectively. This not only improves the structural strength of the side pole 700 but also directly defines the connecting groove 720 without the need to design other structures to form the connecting groove 720. As a result, the structure of the vehicle-mounted platform is simpler and easier to produce and manufacture.

[0090] The telescopic rod 500 can be telescoped in the left-right direction, that is, the movable end of the telescopic rod 500 moves to drive the connecting piece 730 to move relative to the longitudinal beam 610 in the left-right direction, and then drive the side pole 700 to move relative to the longitudinal beam 610 in the left-right direction, so that the tent cloth is unfolded and retracted. The structure for controlling the movement of the side pole 700 by controlling the telescoping of the telescopic rod 500 is relatively simple, which is convenient for design and reduces the design and manufacturing costs of the vehicle-mounted platform.

[0091] In some embodiments of the utility model, as shown in Figure 1 and Figure 3 The cross beam 800 is a hollow structure, the telescopic rod 500 is inserted into the cross beam 800, and the cross beam 800 extends in the left-right direction to the side of the connecting piece 730 close to the longitudinal beam 610, so that the connecting piece 730 is attached to the cross beam 800 when the side pole 700 is in the retracted position.

[0092] In the embodiment, when the account cloth is in the retracted state, the telescopic rod 500 is accommodated inside the hollow cross beam 800, and the connecting piece 730 closely fits on the cross beam 800, avoiding exposure of the telescopic rod 500 and further avoiding the telescopic rod 500 from being bumped, thereby improving the service life of the telescopic rod 500. The telescopic rod 500 is inserted inside the cross beam 800, and the fixed end of the telescopic rod 500 is fixedly connected with the inside of the cross beam 800, not only making the cross beam 800 play a protective role on the telescopic rod 500, but also making the telescopic rod 500 not occupy additional space, thereby improving the space utilization rate. Moreover, the connecting piece 730 fits on the cross beam 800, further making the fixing of the connecting piece 730 more stable, and avoiding the connecting piece 730 from being violently shaken.

[0093] In some embodiments of the utility model, as shown in Figure 5 The first transverse frame rod 210 is a hollow structure, and at least three vertical vertical plates are connected between the upper wall and the lower wall of the first transverse frame rod 210.

[0094] In the embodiment, since the first transverse frame rod 210 is a hollow rod, although the overall weight of the vehicle-mounted platform is reduced and the energy consumption of the vehicle is reduced, the structural strength of the hollow rod is poor, and the vertical plate is designed in the utility model, so that the upper and lower sides of the vertical plate are connected to the upper and lower side walls of the first transverse frame rod 210, thereby improving the structural strength of the first transverse frame rod 210.

[0095] In some embodiments of the utility model, the second transverse frame rod 310 is a hollow structure, and at least three vertical vertical plates are connected between the upper wall and the lower wall of the second transverse frame rod 310.

[0096] In the embodiment, since the second transverse frame rod 310 is a hollow rod, although the overall weight of the vehicle-mounted platform is reduced and the energy consumption of the vehicle is reduced, the structural strength of the hollow rod is poor, and the vertical plate is designed in the utility model, so that the upper and lower sides of the vertical plate are connected to the upper and lower side walls of the second transverse frame rod 310, thereby improving the structural strength of the second transverse frame rod 310.

[0097] In some embodiments of the utility model, as shown in Figure 5 In the case that at least three vertical vertical plates are connected between the upper wall and the lower wall of the first transverse frame rod 210, T-shaped grooves with openings outward are formed in the front side and / or the rear side of the first transverse frame rod 210, and the vertical plates on the front side and / or the rear side form the groove bottoms of the T-shaped grooves.

[0098] In the embodiment, the arrangement of the vertical plate not only improves the structural strength of the first transverse frame rod 210, but also forms T-shaped grooves for mounting the rollers 410, without the need to design other structures to form the T-shaped grooves, so that the structure of the vehicle-mounted platform is simpler and easier to produce and manufacture.

[0099] In some embodiments of the utility model, in the case that at least three vertical vertical plates are connected between the upper wall and the lower wall of the first transverse frame rod 210, the front side and / or the rear side of the second transverse frame rod 310 is formed with a T-shaped groove with the opening outward, and the vertical plate at the front side and / or the rear side forms the groove bottom of the T-shaped groove.

[0100] In the embodiment, the setting of the vertical plate not only improves the structural strength of the second transverse frame rod 310, but also forms the T-shaped groove for mounting the roller 410, without the need to design other structures to form the T-shaped groove, so that the structure of the vehicle-mounted platform is simpler, facilitating production and manufacturing.

[0101] In some embodiments of the utility model, in the case that the fixing part 420 is fixedly connected to the front side and the rear side of the first transverse frame rod 210, at least two fixing parts 420 are arranged on the front side and the rear side of each first transverse frame rod 210 to improve the stability of the first platform 200.
