[0027] The following further describes the embodiments of the present invention with reference to the accompanying drawings:

[0028] As shown in the figure, a roof crossbar bracket includes a crossbar 1, a clamping device installed at both ends of the crossbar 1 and with adjustable spacing, and a housing 2 that partially wraps the clamping device. The clamping device includes a bracket 3, a hook connection mechanism 4 installed on the bracket 3, and a locking mechanism 5;

[0029] The hook connection mechanism 4 includes a base plate 41 installed below the bracket 3, a mounting plate 42 fixedly installed in the bracket 3, and a hook plate 43 movably installed on the mounting plate 42. The hook plate 43 is located on one side of the base plate 41. A first adjustment component for adjusting the included angle between the hook plate 43 and the mounting plate 42 and a second adjustment component 6 for adjusting the installation height of the hook plate 43 on the mounting plate 42 are provided between the hook plate 43 and the mounting plate 42. The hook connection mechanism in this technical solution can realize the function of the roof bracket adapting to the roofs of different vehicles by adjusting the relative position between the hook plate and the mounting plate. The base plate presses on the roof surface, and the hook plate hooks the hook groove on the door frame or the door edge. The base plate and the hook plate cooperate with each other to firmly install the hook connection mechanism on both sides of the roof. In addition, the upper and lower height and the inclination angle of the hook plate are adjusted by the first adjustment component and the second adjustment component respectively, so that the hook connection mechanism adapts to the roofs of different models of vehicles, having the advantages of good versatility, convenient adjustment, and high working reliability.

[0030] In addition, the crossbar and the locking mechanism in this embodiment have been disclosed in the patent with the application number 2022210581133, and will not be elaborated here.

[0031] On the upper surface of the base plate 41, there is a vertically arranged mounting piece 411. The mounting piece 411 is rotatably mounted at the bottom of the bracket 3. On the lower surface of the base plate 41, there is a soft pad 413.

[0032] Between the mounting piece 411 and the bottom of the bracket 3, there are a third bolt 414 and a third nut 412 connecting the two. The third nut 412 is a lock nut or a welded nut. When the base plate is placed on the roof surface, since the mounting piece and the bracket are rotatably connected, the base plate will automatically adjust the tilt angle and fit the roof surface. After the cross bar and the hook plate are installed in place, the base plate will be automatically fixed, and the base plate will automatically fit the roof surface.

[0033] In this technical solution, there are two embodiments for the rotatable connection between the base plate and the bracket. Embodiment 1: The third nut is a lock nut; Embodiment 2: The third nut is an ordinary nut, and the ordinary nut is welded to the mounting piece. After one end of the third bolt is threadedly connected to the ordinary nut, the other end of the third bolt will be blocked by the housing. The above two embodiments can ensure that the third nut and the third bolt will not become disengaged, effectively ensuring the effective connection between the base plate and the bracket.

[0034] The soft pad can prevent hard contact and protect the paint surface of the roof.

[0035] At the upper end of the mounting plate 42, there is a first insertion block 421, and on both sides thereof, there are second insertion blocks 422. On the upper surface of the bracket 3, there is a first slot 31 corresponding to the first insertion block 421, and at both sides thereof, there are second slots 32 corresponding to the second insertion blocks 422. After the mounting plate 42 and the bracket are in plug-in fit, they are fixed by welding. The cooperation between the first insertion block and the first slot and between the second insertion block and the second slot enables the mounting plate to be positioned accurately before welding, with the advantages of good mounting accuracy and convenient operation.

[0036] The hook plate 43 includes a straight plate portion 431 at the upper end and a hook claw portion 432 at the lower end. The second adjustment assembly 6 includes a strip-shaped groove 61 and a second bolt 62. The strip-shaped groove 61 is arranged vertically on the straight plate portion 431. The second bolt 62 passes through the strip-shaped groove 61 and is in threaded cooperation with the mounting plate 42. After loosening the second bolt, manually adjust the hook plate to change the relative position between the strip-shaped groove and the second bolt, and the mounting height of the hook plate on the mounting plate can be adjusted.

[0037] Between the second bolt 62 and the strip-shaped groove 61, there is a gasket 63. One surface of the gasket 63 in contact with the strip-shaped groove 61 is spherical, and the surface in contact with the second bolt 62 is flat. Even if the straight plate portion tilts under the action of the first adjustment assembly, the second bolt can still play a firm fixing role.

[0038] The first adjustment component includes a first bolt 7 threadedly engaged with the upper end of the straight plate portion 431. The end of the first bolt 7 is in contact and cooperation with the side wall of the mounting plate 42. The side wall of the mounting plate 42 is inclined. The end of the first bolt 7 is spherical. The mounting plate 42 is provided with a groove 424 in contact and cooperation with the end of the first bolt 7. On the premise that the mounting plate is fixed, when the first bolt is rotated, the straight plate portion changes its angle through the threaded cooperation between the first bolt and the straight plate portion, thereby adjusting the inclination angle of the hook plate. The groove can limit the end of the first screw within the groove range, greatly improving the working stability of the first adjustment component;

[0039] In addition, the end face of the first bolt is spherical, which can reduce the wear on the mounting plate.

[0040] In addition, the cooperation between the first adjustment component and the second adjustment component in this embodiment can realize various installation methods of the hook plate, such as Figure 6 shown, which discloses the states of the hook plate at different installation heights and different inclination angles, so that the hooking mechanism in this embodiment can adapt to the roofs of vehicles of respective models.

[0041] A first nut 433 is fixedly installed on the side wall of the straight plate portion 431 and is threadedly engaged with the first bolt 7. A second nut 423 is fixedly installed on the side wall of the mounting plate 42 and is threadedly engaged with the second bolt 62. Both the first nut and the second nut are fixed by welding or can adopt an integrally formed structure.

[0042] After the hook plate in this embodiment hooks the hook groove on the car door frame or the car door edge, the base plate fits on the surface of the car roof and automatically adjusts to the appropriate angle. Then, the second bolt is rotated by a tool to make the hook plate gradually approach the mounting plate. Then, the first bolt is rotated by a tool. During the rotation of the first bolt, a force is applied to the mounting plate, and the mounting plate applies a reaction force to the upper end of the hook plate, making the upper end of the hook plate gradually move away from the mounting plate. At the same time, the lower end of the hook plate firmly hooks the hook groove on the car door frame or the car door edge due to the lever principle, which has the advantages of convenient operation and firm installation.

[0043] The housing 2 includes a front cover plate 21 and a rear cover plate 22. A lock core member 23 is installed on one side of the front cover plate 21. A limiting plate 24 is provided at a position corresponding to the lock core member 23 on the rear cover plate 22. A passing hole 25 is provided on the limiting plate 24. A first clamping platform 26 extending outward is provided in the circumferential direction at the end of the lock core member 23. The lock core member 23 has a first state in which the first clamping platform 26 can pass through the limiting plate 24 after being aligned with the passing hole 25 and a second state in which the first clamping platform 26 cannot pass through the limiting plate 24 after being misaligned with the passing hole 25. The lock core member needs to be rotated by a key. In this embodiment, the lock core member is rotated by a key. After rotating 90°, when the first clamping platform is aligned with the passing hole, the operator can separate the front cover plate and the rear cover plate. On the contrary, when the first clamping platform is misaligned with the passing hole, the two are in a snap-fit state and the front cover plate and the rear cover plate cannot be separated.

[0044] On the other side of the front cover plate 21, a second clamping platform 27 is provided. On the other side of the rear cover plate 22, a second clamping groove 28 that is snap-fitted with the second clamping platform 27 is provided. Since the lock core member is provided on one side of the housing, it is easy to cause a gap on the other side of the housing, affecting the working stability. Therefore, a second clamping platform and a second clamping groove are provided on the other side of the housing to ensure the stable connection between the front cover plate and the rear cover plate.

[0045] A relief groove 29 is provided at a position on the rear cover plate 22 corresponding to the mounting piece to prevent interference when the base plate adjusts the angle.
