[0002] With the development of the national economy and the improvement of people's living standards, the status of cars in people's production and life has become increasingly important. Many cars are equipped with car luggage racks on their roofs. The car luggage racks generally include two cross bars. On the basis of the cross bars, bicycle racks, skis, kayaks, roof boxes, roof baskets and other carrying racks can be carried.

[0003] As people's living standards improve, their leisure and entertainment options are becoming increasingly diverse. Skiing has become a very popular form of leisure and entertainment in recent years. To facilitate the transportation of skis, snowboards, and other equipment on the roof, a specialized mounting bracket (e.g., a ski rack) needs to be installed on the roof rack. Publication No. CN214112425U discloses an easy-to-install roof ski rack. The ski rack's mounting components utilize a clamping foot and a U-shaped screw to form a space that clamps the aluminum rod of the luggage rack. This structure uses nuts to secure both ends of the U-shaped screw, making installation and removal cumbersome and inconvenient. Furthermore, the locking nut of the U-shaped screw is exposed on the roof rack, lacking any anti-theft functionality, making the ski rack and skis easily lost. Summary of the Invention

[0004] First, to address the issue of convenient installation between a ski rack and a luggage rack, the present invention provides a ski mounting rack for a car roof. This mounting rack utilizes a clamping mechanism to quickly and conveniently secure the entire structure to the luggage rack, making installation and operation convenient and easy.

[0044] like Figures 1 to 8 As shown, according to an embodiment of the present invention,

[0045] A ski mounting rack for a car roof comprises a ski rack, on which is mounted a fixing frame 3, the fixing frame 3 comprising a clamping jaw base 301 and two clamping jaws 302; the clamping jaw base 301 is mounted on the ski rack; the two clamping jaws 302 are arranged opposite each other and are rotatably mounted on the clamping jaw base 301 via a hinge; the clamping jaw base 301 is provided with a clamping jaw adjustment structure, which acts on the clamping jaws 302 to rotate them, thereby adjusting the opening distance between the two clamping jaws 302.

[0046] A specific embodiment of the clamping jaw base 301 is as follows: the clamping jaw base 301 is box-shaped, and the tail ends of the clamping jaws 302 are rotatably mounted within the clamping jaw base 301. The clamping jaw base 301 is provided with clearance openings corresponding to the two clamping jaws 302. The heads of the clamping jaws 302 extend through the corresponding clearance openings to form a clamping portion, which is away from the ski rack. The clamping jaws 302 are generally L-shaped to improve stability after clamping.

[0047] The clamping portion can be coated with soft material (such as a rubber pad) to protect the aluminum rod of the luggage rack. Similarly, the position where the outer wall of the clamping claw base 301 contacts the aluminum rod of the luggage rack can also be coated with soft material.

[0048] Typically, the ski rack is in the shape of an elongated strip. Based on the considerations of installation stability and economy, a fixing frame 3 is installed at each end of the ski rack.

[0049] To facilitate the installation of skis / sleds, the ski rack includes an upper cleat 1 and a lower cleat 2 that cooperate with each other. The upper cleat 1 is assembled on the lower cleat 2 in an open-close manner. Specific open-close assembly methods include sliding and pulling, and flip-up. The fixing frame 3 is mounted on the lower cleat 2. A more specific open-close assembly method is: the upper cleat 1 is superimposed on the lower cleat 2, and either end of the upper cleat 1 and the lower cleat 2 are hinged to each other, with the skis / sled clamped between the upper cleat 1 and the lower cleat 2. To achieve rapid opening or locking of the upper cleat 1 and the lower cleat 2, a locking connection mechanism is provided at the free ends of the upper cleat 1 and the lower cleat 2. The locking connection mechanism can adopt any existing form. Its main purpose is to achieve locked connection and separation of the upper cleat 1 and the lower cleat 2. From the perspective of anti-theft, the locking connection mechanism adopts a mechanical lock with a key.

[0050] Regarding the jaw adjustment structure, its specific forms include but are not limited to the following four forms: telescopic, rotating, cam, and force storage. As a further explanation, each form of the jaw adjustment structure is described in detail:

[0051] (1) The clamping jaw adjustment structure is a telescopic component, the telescopic direction of the telescopic component is perpendicular to the rotation center line of the clamping jaw 302, and the telescopic movable part of the telescopic component is linked with the clamping jaw 302 to push the clamping jaw 302 to rotate around the hinge.

[0052] Of course, the telescopic assembly can have a variety of structures, such as a guide rod-sleeve structure, a slide rail-slider structure, and a screw rod-nut structure. Corresponding mounting locations need to be set on the clamping jaw base 301. The installation methods of various forms of telescopic assemblies are well known to those skilled in the art and will not be described in detail here. Those skilled in the art also have the following common sense: in actual applications, a "guide rod" or "sleeve", "slide rail" or "slider", "screw rod" or "nut" can all form the telescopic movable portion; the telescopic movable portion can abut against the clamping jaw 302 or can be hinged via a connecting rod.

[0053] (2) The clamp adjustment structure is a rotating assembly, the hinge is fixedly connected to the clamp 302 in an annular direction, and the output shaft of the rotating assembly is transmission-connected to the hinge to drive the hinge to rotate, and at the same time drives the clamp 302 to rotate around the hinge.

[0054] The output shaft of the rotating assembly can be connected to the hinge coaxially to directly drive the hinge.

[0055] Generally, the input and output shafts of the rotating assembly can be combined into one to simplify the structure, i.e., the input and output of the rotating power are on the same shaft. The rotating assembly can also be configured as a single-stage or multi-stage transmission system (such as gears) so that the input and output shafts are independent of each other.

[0056] The driving mode of the rotating assembly can be electric or manual. When manual driving is adopted, a rocker arm perpendicular to the input shaft of the rotating assembly can be connected to the input shaft of the rotating assembly.

[0057] An installation area for installing the rotating assembly is provided on the clamping jaw base 301 , and the rotating assembly (shaft) is installed on the clamping jaw base 301 via a bearing.

[0058] (3) The clamping jaw adjustment structure is a cam assembly, and the cam of the cam assembly acts on the clamping jaw 302 to drive it to rotate around the hinge.

[0059] The cam assembly also includes a camshaft, which is mounted on the clamp base 301 through a bearing. The cam is mounted on the camshaft. The camshaft can be driven electrically or manually. When manual drive is adopted, a rocker arm perpendicular to the input shaft of the rotating assembly can be connected to the input shaft.

[0060] (4) The clamping jaw adjustment structure is a clamping force storage component, and the clamping force storage component includes a force storage spring, which is connected between the clamping jaw 302 and the clamping jaw base 301;

[0061] The force storage spring can be a force storage torsion spring or a force storage compression spring. Its function is: when the two clamps 302 are rotated and the distance between them is expanded around the hinge, the clamps 302 compress the force storage spring to store energy, and the force storage spring generates a tendency to push the two clamps 302 to rotate and reduce the distance between them.

[0062] As a preferred solution, in the above first method, the telescopic assembly includes an adjusting bolt 4 and an adjusting nut 5 threadedly mounted thereon; a telescopic limiter is provided on the clamp base 301, which acts on the adjusting nut 5 to constrain it from moving forward and backward axially along the adjusting bolt 4, and the adjusting bolt 4 is linked with the clamp 302 to drive it to rotate around the hinge.

[0063] In order to provide an anti-theft function for the ski rack, the adjusting bolt 4 is movable through the lower clamping plate 2 and extends into the clamping jaw base 301 , with the head of the adjusting bolt 4 being located between the upper clamping plate 1 and the lower clamping plate 2 ;

[0064] When the upper clamping plate 1 is opened relative to the lower clamping plate 2, the head of the adjusting bolt 4 is exposed to allow the user to adjust;

[0065] When the upper clamping plate 1 is closed relative to the lower clamping plate 2 , the head of the adjusting bolt 4 is hidden in the ski frame, specifically, hidden between the upper clamping plate 1 and the lower clamping plate 2 .

[0066] The tail ends of the two clamping jaws 302 are located between the head of the adjusting bolt 4 and the adjusting nut 5, and the tail ends of the two clamping jaws 302 are respectively against the adjusting nut 5;

[0067] The hinge is a rotating pin 303, and an expansion torsion spring 304 is sleeved on the rotating pin 303, and the two ends of the expansion torsion spring 304 are respectively hooked on the clamping jaw 302 and the clamping jaw base 301; the specific process of clamping and opening the two clamping jaws 302 is: when the adjusting bolt 4 is rotated, the adjusting nut 5 is constrained by the telescopic limit member and moves toward the head of the adjusting bolt 4, pushing the two clamping jaws 302 to rotate, so that the heads of the two clamping jaws 302 are close to each other and clamped, thereby making them grasp the aluminum rod of the luggage rack, and at the same time, the expansion torsion spring 304 is compressed and stores energy; when the adjusting bolt 4 is reversed, the adjusting nut 5 is constrained by the telescopic limit member and moves toward the tail of the adjusting bolt 4, and the expansion torsion spring 304 releases the accumulated energy, causing the two clamping jaws 302 to rotate in the opposite direction and open.

[0068] Under normal conditions, the jaws 302 are open, allowing the expansion torsion spring 304 to relax, extending the life of the expansion torsion spring 304. The jaws 302 are constantly in either the "open" or "clamped" state, simplifying installation and removal. The rotation of the jaws 302 is controlled by the coordination of the adjusting bolt 4, the adjusting nut 5, and the expansion torsion spring 304, resulting in a simple structure that significantly reduces costs and malfunction rates.

[0069] For greater user convenience, a bolt adjustment wrench 18 is movably embedded in the ski frame. The bolt adjustment wrench 18 can be movably inserted into the ski frame in any manner. A preferred embodiment is to place the bolt adjustment wrench 18 between the upper clamping plate 1 and the lower clamping plate 2. A further preferred embodiment is to movably insert the bolt adjustment wrench 18 into the lower clamping plate 2. Commonly, the bolt adjustment wrench 18 is a hexagonal wrench, and the adjustment bolt 4 is a hexagonal bolt.

[0070] A specific implementation of the telescopic limit member is: the adjusting nut 5 is connected to the limiting block, and a limiting groove 6 is provided on the clamp base 301 corresponding to the limiting block, and the limiting block is assembled in the limiting groove 6. The limiting block and the limiting groove 6 cooperate with each other to form the telescopic limit member, and the length direction of the limiting groove 6 is parallel to the length direction of the adjusting bolt 4. The limiting block is constrained by the limiting groove 6 and moves along its length direction.

[0071] In order to facilitate manufacturing and installation, the clamping jaw base 301 is a split structure, including a base and a box body that is buckled on the base.

[0072] The upper and lower splints 1 and 2 are both made of profiles, and are provided with end shells at their ends for shielding, connecting, and installing functions. Specifically, the lower splint 2 includes a lower splint body and a first lower cover 7, which is mounted on the free end of the lower splint body. The upper splint 1 includes an upper splint body and a first upper cover 8, which is mounted on the free end of the upper splint body. The locking connection mechanism is provided between the first lower cover 7 and the first upper cover 8. Based on this, the locking connection mechanism includes an anti-theft lock 805, which can be used to lock the first lower cover 7 and the first upper cover 8 to prevent opening without the user's consent.

[0073] The lower splint body is a split structure, which also includes a strip-shaped fixed plate 2b and a sliding plate 2a. The sliding plate 2a can be slidably installed on the fixed plate 2b. The upper splint 1 is hinged to the fixed plate 2b. The sliding direction of the sliding plate 2a is consistent with the length direction of the fixed plate 2b. The first lower cover 7 is connected to the free end of the sliding plate 2a. The free end of the fixed plate 2b is installed with a lower sealing end cover 9. The fixing frame 3 is installed on the fixed plate 2b.

[0074] The first upper cover 8 further includes a fixed cover body 801 mounted on the upper clamping plate 1 , and the anti-theft lock 805 is used for locking and unlocking the first lower cover 7 and the fixed cover body 801 .

[0075] The fixed cover 801 is also equipped with a push-type cover 802. Specifically, a cover hole is provided on the fixed cover 801. The push-type cover 802 is arranged at the cover hole and is rotatably connected to the fixed cover 801 through a cover shaft 803. A cover torsion spring 804 is installed on the cover shaft 803. One end of the cover torsion spring 804 presses against the inner wall of the fixed cover 801, and the other end presses against the inner wall of the push-type cover 802. The lower part of the push-type cover 802 has a hook-shaped portion, and a hook groove is provided on the corresponding hook portion on the first lower cover 7. When the hook portion is hooked in the hook groove, the push-type cover 802 is in a closed state. Pressing the push-type cover 802 to rotate it to a certain angle can disengage the hook portion from the groove, thereby unlocking the push-type cover 802.

[0076] A more specific structure of the sliding plate 2a is as follows: the sliding plate 2a includes a flat plate portion 2a2 and an arched lower three-dimensional portion 2a1, wherein the lower three-dimensional portion 2a1 is mounted on the flat plate portion 2a2;

[0077] A more specific structure of the upper splint 1 is as follows: the upper splint 1 includes a cover plate 101 and an upper three-dimensional portion 102, wherein the cover plate 101 is provided on the surface of the upper three-dimensional portion 102, and the upper three-dimensional portion 102 corresponds to the lower three-dimensional portion 2a1;

[0078] The flat plate portion 2a2 is slidably mounted on the fixed plate 2b. Specifically, a sliding groove is provided on the lower surface of the flat plate portion 2a2, and a convex strip corresponding to the sliding groove is provided on the upper surface of the fixed plate 2b. The convex strip is movably inserted into the sliding groove so that the flat plate portion 2a2 can slide relative to the fixed plate 2b. The flat plate portion 2a2, the fixed plate 2b and the cover plate 101 are generally made of aluminum profiles.

[0079] The clamping jaw base 301 is fixedly mounted on the fixing plate 2b, and a circular clamping jaw adjustment hole is opened on the flat plate portion 2a2 corresponding to the adjustment bolt 4. The free end length of the lower three-dimensional portion 2a1 is slightly shorter than that of the flat plate portion 2a2, so that the clamping jaw adjustment hole can be exposed after opening the first upper cover 8.

[0080] The hinged end of the upper splint 1 is installed with a second upper cover 20, and the hinged end of the fixed plate 2b is installed with a second lower cover 21. The second upper cover 20 and the second lower cover 21 are hinged by a hinge shaft 23, and a hinge torsion spring 22 is installed on the hinge shaft 23. One end of the hinge torsion spring 22 is pressed against the second upper cover 20, and the other end of the hinge torsion spring 22 is pressed against the second lower cover 21. The end of the sliding plate 2a away from the first lower cover 7 is installed with a slide plate sealing cover 19. Specifically, the slide plate sealing cover 19 is installed on the flat portion 2a2. When the sliding plate 2a slides out, when the slide plate sealing cover 19 interferes with the lower sealing end cover 9, the flat portion 2a2 of the sliding plate 2a reaches the sliding limit and stops.

[0081] A sliding locking structure is provided between the lower sealing end cover 9 and the sliding plate 2a. Figure 2 and 3 As can be seen in the figure, the sliding locking structure is located on the portion of the flat plate portion 2a2 that is longer than the lower three-dimensional portion 2a1. The sliding locking structure includes a regulating vertical plate 10, a connecting plate 11, a movable vertical plate 12 and a locking plate 13.

[0082] The first lower cover 7 is provided with the regulating plate 10, which is provided with an arc-shaped regulating hole 14. The connecting plate 11 is mounted on the flat plate portion 2a2 of the sliding plate 2a. The movable plate 12 is rotatably mounted on the connecting plate 11. The upper end of the movable plate 12 is bent and passes through the regulating hole 14 to form a regulating handle 15. The regulating handle 15 is provided with an adjusting knob 17. The lower end of the movable plate 12 is bent to form a locking portion 16.

[0083] The locking plate 13 is provided on the lower sealing end cover 9. Figure 7 As shown, when the locking portion 16 contacts the locking plate 13, the sliding plate 2a is locked. Figure 8 As shown, the regulating handle 15 is rotated to disengage the locking portion 16 from the locking plate 13, and the sliding plate 2a is unlocked. At this time, the sliding plate 2a can slide. In this embodiment, unlocking can be achieved after rotating it counterclockwise for a certain angle.

[0084] The regulating vertical plate 10 is provided with a wrench insertion hole, and the bolt adjusting wrench 18 passes through the wrench insertion hole and extends into the interior of the lower three-dimensional part 2a1. The bolt adjusting wrench 18 is generally an L-shaped wrench.

[0085] Figure 9-11 The process of assembling the ski mounting rack of the present invention with the roof luggage rack of the car is demonstrated. In the first step, the fixing bracket 3 is first installed near the sliding end of the sliding plate 2a; in the second step, the sliding plate 2a is unlocked to slide it out, and then the fixing bracket 3 at this end is installed; in the third step, the opening distance of the two clamps is adjusted by using the clamp adjustment structure and the clamps are clamped on the aluminum rod of the luggage rack. At this time, the installation is completed. When the skis / sleds need to be placed, the push-type cover 802 is pressed to unlock the push-type cover 802 and the first lower cover 7, the sliding plate 2a is pulled out, the skis are placed, the push-type cover 802 is pressed to lock the push-type cover 802 and the first lower cover 7, and then the anti-theft lock 805 is used to further lock it. The placement of the skis / sleds is completed, and the reverse operation can be performed when the skis are taken out.

[0086] By adopting the technical solution of the present invention, the aluminum rod of the luggage rack is grasped by the clamping claws, thereby fixing it on the roof. By adjusting the opening distance between the two clamping claws, it can adapt to the aluminum rods of the luggage rack of different sizes. The sliding plate can be slid out to take out the sled.
