[0038] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0039] Embodiment 1

[0040] This embodiment relates to a hidden roof luggage rack assembly, which is arranged on the roof assembly of a vehicle, thereby providing a luggage rack configuration scheme in which the luggage rack can be retracted into the roof assembly; an exemplary structure thereof is as follows Figures 1 to 5 shown.

[0041] In general, the hidden roof luggage rack assembly includes a receiving slot 11 provided on a top cover 10 of the roof assembly, a frame 2 that can be received in the receiving slot 11, and a connecting rod mechanism. The connecting rod mechanism includes a plurality of four-link groups 3 provided at the bottom of the receiving slot 11, and a motor disposed on at least one of the four-link groups 3. The frame 2 is supported on each of the four-link groups 3. The motor drives the corresponding four-link group 3 to move, which can drive the frame 2 to rise and fall, so that the frame 2 rises to the outside of the receiving slot 11, or falls back into the receiving slot 11.

[0042] Preferably, in this embodiment, the frame 2 adopts a rectangular frame structure, and each of the four corners of the frame 2 is provided with a four-bar linkage 3. Moreover, each four-bar linkage 3 is configured with a motor. The frame 2 adopts a rectangular frame structure, which is not only convenient for construction, but also has a standardized and reasonable appearance, which is suitable for the shape of the roof, and is also convenient for installing accessories such as roof luggage boxes and storage racks on the frame 2. Based on the overall shape characteristics of the frame 2, a four-bar linkage 3 is respectively provided at the four corners of the frame 2 to provide reliable support for the frame 2; a motor is configured for each four-bar linkage 3, and each motor runs synchronously under the control of the internal buttons of the vehicle or the remote control, which can drive the four four-bar linkages 3 to swing synchronously, thereby driving the frame 2 to perform a smooth lifting and lowering action, which is conducive to improving the driving performance of the entire connecting rod mechanism and its action reliability.

[0043] Specifically, the frame 2 of this embodiment includes two longitudinal beams 21 arranged in parallel, and two transverse beams 22 respectively connected between the front ends and the rear ends of the two longitudinal beams 21; the receiving groove 11 includes a longitudinal groove 110 for receiving the longitudinal beams 21, and a transverse groove 111 for receiving the transverse beams 22. The frame 2 is assembled in the form of two longitudinal beams 21 and two transverse beams 22, which is convenient for the separate construction and processing of each beam body, as well as the transportation and storage of the beam body assembly of the frame 2 before assembly; the receiving groove 11 is provided with the longitudinal groove 110 and the transverse groove 111 according to the appearance of the longitudinal beams 21 and the transverse beams 22, so as to ensure that the receiving groove 11 can completely receive and hide the frame 2.

[0044] like Figure 6As shown, an inner cavity 20 is formed in the longitudinal beam 21 of this embodiment; moreover, the cross beam 22 abuts against the side of the longitudinal beam 21, and is fixedly connected to the longitudinal beam 21 through a connector 23 penetrating the side wall of the longitudinal beam 21. The structure of each beam body of the frame body 2 can of course be flexibly set. Preferably, each beam body adopts a hollow structure to reduce the self-weight of the beam body; in particular, an inner cavity 20 is formed in the longitudinal beam 21. Based on the setting of the inner cavity 20, the end of the cross beam 22 of this embodiment abuts against the inner side wall of the longitudinal beam 21, and the cross beam 22 and the longitudinal beam 21 are fixedly connected by a connector 23 such as a bolt; the connector 23 passes through the inner side wall of the longitudinal beam 21 (facing the cross beam 22) from the inner cavity 20 of the longitudinal beam 21, and is screwed to the end of the cross beam 22, and the assembly between the longitudinal beam 21 and the cross beam 22 is completed. Such a configuration not only ensures that the connector 23 is not exposed, but also allows the top surfaces of the longitudinal beam 21 and the cross beam 22 to be located on the same plane, which is conducive to the entire frame 2 being completely hidden in the receiving groove 11, and making the surface of the roof assembly flush. The opening of the inner cavity 20 at the end of the longitudinal beam 21 can be sealed with accessories such as end caps and plugs after the connector 23 is assembled.

[0045] Still Figure 2 , Figure 3 As shown, the four four-link groups 3 located at the four corners of the frame 2 can of course be connected to the longitudinal beam 21, such as Figure 2 As shown, the four four-bar linkages 3 are respectively arranged at the two ends of the two transverse grooves 111; alternatively, the four four-bar linkages 3 can also be connected to the crossbeam 22, as shown in FIG. Figure 3 As shown, four four-link groups 3 are respectively arranged at the two ends of the two longitudinal grooves 110. Preferably, each four-link group 3 of this embodiment is arranged in the longitudinal groove 110 along the front-rear direction of the vehicle, and the four four-link groups 3 are respectively arranged near the front and rear ends of the two longitudinal beams 21. Among them, the four-link group 3 located at the front end of the longitudinal groove 110 is supported below the front end of the longitudinal beam 21, and the four-link group 3 located at the rear end of the longitudinal groove 110 is supported below the rear end of the longitudinal beam 21; the longitudinal beam 21 and the connecting rod 32 at the top of the four-link group 3 can be fixedly connected by bonding, welding or riveting.

[0046] There are of course many design solutions for the specific structural form of the four-link group 3. Figure 7 , Figure 8As shown, the four-linkage group 3 of this embodiment includes a base 30, a first swing rod 311 and a second swing rod 312 arranged at intervals on the base 30, and a connecting rod 32 connected between the top of the first swing rod 311 and the top of the second swing rod 312; the frame 2 is connected to the top of the connecting rod 32. The first swing rod 311 and the second swing rod 312 are arranged at intervals on the base 30, and the connecting rod 32 for supporting the frame 2 is connected between the tops of the first swing rod 311 and the second swing rod 312. When the first swing rod 311 or the second swing rod 312 is driven by the motor to swing, the first swing rod 311 and the second swing rod 312 will swing synchronously, and the connecting rod 32 will translate with the swing of the two swing rods, and the height position will change. The overall structure is simple and effective, which is convenient for making the entire four-linkage group 3 more delicate and miniaturized, so as to adapt to the narrow installation space conditions inside the receiving groove 11.

[0047] Specifically, the base 30 of this embodiment includes a first base 301 corresponding to the first swing rod 311, and a second base 302 corresponding to the second swing rod 312. The motor is arranged on the first base 301 to drive the first swing rod 311 to swing. The bottom end of the first swing rod 311 is hinged on the first base 301, and the bottom end of the second swing rod 312 is hinged on the second base 302. The two ends of the connecting rod 32 are respectively hinged to the top of the first swing rod 311 and the top of the second swing rod 312 through a hinge shaft 320. Among them, the motor can be integrated in the first base 301, and the rotating shaft 34 of the motor is fixedly connected to the bottom end of the first swing rod 311. When the motor runs and rotates, it can drive the first swing rod 311 to swing, and then drive the second swing rod 312 to swing through the connecting rod 32, and the connecting rod 32 realizes the change of height position.

[0048] The base 30 is designed to be composed of a first base 301 and a second base 302, which are respectively used to accommodate the first rocker arm 311 and the second rocker arm 312. This not only saves unnecessary connecting parts between the first base 301 and the second base 302 and reduces the weight of the base 30 itself; but also, according to the installation position requirements of the motor, the first base 301 can be correspondingly designed to be wider to facilitate the installation and arrangement of the motor, and provide a reliable swinging foundation for the first rocker arm 311 serving as an active rocker arm.

[0049] In this embodiment, the first base 301 and the second base 302 are both fixed to the bottom of the receiving groove 11. There are many specific ways of fixing. Preferably, the first base 301 and the second base 302 of this embodiment are both fixed to the roof assembly by rivets 33, so that the two bases 30 are fixed to the sheet metal of the roof assembly. The riveting method has the advantages of reliable connection performance; and the head size of the rivet 33 is small, which can save the internal space of the receiving groove 11.

[0050] like Fig. 9 , Fig.10 and Fig.11 As shown, when the motor is controlled by the remote control key switch, the motor is controlled to rotate counterclockwise as shown in the figure, and the connecting rod 32 can reach Fig. 9 The frame 2 is then lowered into the receiving groove 11 and hidden. When the control motor rotates clockwise, the first swing rod 311 and the second swing rod 312 swing clockwise, and the connecting rod 32 is lifted to the lowest position as shown. Fig.10 As the motor continues to drive, the connecting rod 32 can reach the middle position shown in FIG. Fig.11 In the highest position shown, the frame 2 is completely raised out of the receiving slot 11 and is in a state of being able to carry items such as a suitcase.

[0051] The lifting height of the frame 2 can be set to about 50 mm, and the connecting rod 32 can be provided with locking structures at the lowest position and the highest position to prevent the frame 2 from shaking in the use state position and the folded state position.

[0052] As for the materials of the frame 2, the top cover 10 and the four-link group 3, the frame 2 is preferably made of ABS plastic; the top cover 10 is preferably made of 0.7 mm thick ordinary steel plate; the four-link group 3 is preferably made of 35 steel. The rivets 33 used to fix the first base 301 are preferably aluminum rivets with a diameter of 10 mm, and the rivets 33 used to fix the second base 302 are preferably aluminum rivets with a diameter of 6 mm.

[0053] In summary, the hidden roof luggage rack assembly of the present embodiment is formed with a receiving groove 11 on the top cover 10 of the roof assembly, and the receiving groove 11 can accommodate the frame 2 of the luggage rack assembly; a four-bar linkage is adopted in conjunction with the drive of a motor to drive the frame 2 to perform a smooth lifting and lowering action, so that the frame 2 rises from the receiving groove 11 and is in a state of carrying luggage, or descends back into the receiving groove 11 and is in a state of being folded, thereby providing a luggage rack configuration scheme that can be folded into the roof assembly; the frame 2 is hidden when not in use, which is not only conducive to the neatness and beauty of the top of the vehicle, but also helps to reduce the wind resistance of the vehicle during driving.

[0056] By selecting the hidden roof luggage rack assembly of the first embodiment, when the frame 2 is raised, various common luggage rack accessories can be installed on the frame 2, which is convenient and practical. When the frame 2 is not in use, the hidden frame 2 can be lowered and controlled by remote control, etc., and it can be raised and lowered freely, which is convenient to operate. When the frame 2 is lowered into the receiving groove 11, the top of the roof assembly has a beautiful and neat appearance, and can reduce the wind resistance of the vehicle.

[0057] Moreover, the driving form of the connecting rod mechanism is easy to implement, has stable driving performance, the lifting and lowering action of the frame 2 is smooth, and the manufacturing cost is low.
