Abstract
Description
Technical Field
[0001] This invention belongs to the field of automotive exterior equipment technology, specifically relating to a car roof rack and a car. Background Technology
[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.
[0003] Cars have become an essential tool for daily travel. With the improvement of living standards and the increase in tourism, car roof racks, as devices to expand vehicle storage space, have received widespread attention and application. However, existing car roof racks are usually functionally limited and cannot meet the diverse needs of users in various scenarios; loading and unloading luggage requires climbing up and down, making it inconvenient and labor-saving; and the choice of roof rack models is further restricted due to differences in the structure of different vehicle roofs. Therefore, developing a multifunctional car roof rack that enables convenient and labor-saving luggage loading and unloading, is highly adjustable, adaptable to a wide range of scenarios, and has good stability is of great significance.
[0004] For example, Chinese patent application CN204109912U discloses a roof rack, which includes: a roof rack longitudinal beam, a zinc-aluminum alloy mounting bracket, a welded mounting bracket, and a mounting cover plate; the two ends of the roof rack longitudinal beam form mounting ends, the zinc-aluminum alloy mounting bracket is symmetrically arranged near the two ends of the roof rack longitudinal beam and is detachably connected to the roof rack longitudinal beam by screws, and the zinc-aluminum alloy mounting bracket is also provided with a plurality of first mounting holes; the mounting cover plate is located on the periphery of the zinc-aluminum alloy mounting bracket and abuts against the roof surface of the roof rack longitudinal beam; the mounting ends formed at both ends of the roof rack longitudinal beam are also provided with shock-absorbing pads; the welded mounting bracket is provided with second mounting holes, and the zinc-aluminum alloy mounting bracket and the welded mounting bracket are detachably connected through the first mounting holes and the second mounting holes, and the welded mounting bracket is also provided with a welded surface. Currently, the industry typically adopts the technical solution in this patent application. However, the inventors have discovered that when this solution is applied, it is extremely inconvenient and poses a safety hazard when people frequently load and unload luggage and goods, especially when large and heavy items are involved in activities such as camping and picnicking. Furthermore, in camping and picnicking scenarios, the luggage rack is left empty on the roof of the vehicle and cannot be quickly used as a folding table, barbecue grill, or other convenient outdoor activity, thus limiting its functionality. Summary of the Invention
[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a car roof rack and a car, wherein the load-bearing frame of the roof rack can be moved and rotated via a central rail to change its position, and can be moved and rotated between the load-bearing frame and the central rail, so that the height of the load-bearing frame can be adjusted arbitrarily.
[0006] To achieve the above objectives, the present invention is implemented through the following technical solution:
[0007] In a first aspect, the present invention provides a car roof rack, comprising two fixed rails arranged opposite each other, each fixed rail being connected to an intermediate rail, and a load-bearing frame being provided between the two intermediate rails; a first power device is fixedly provided at one end of each fixed rail, the first power device being connected to a first gear, and the intermediate rail being provided with a first rack and a second rack of different widths, the first gear meshing with the first rack, or the first gear meshing with both the first rack and the second rack, so that the intermediate rail can translate or rotate relative to the fixed rails.
[0008] As a further technical solution, the intermediate track has a central cavity, in which the first rack and the second rack are both disposed, and the first gear extends into the central cavity of the intermediate track; a mounting bracket is provided at the bottom of the fixed track.
[0009] As a further technical solution, the first rack and the second rack are parallel and spaced apart, a portion of the first rack is positioned opposite to the second rack, and the first rack and the second rack are located on both sides of the first gear.
[0010] As a further technical solution, a telescopic rod is provided between the first power device and the first gear, and the telescopic rod can drive the first gear to move horizontally.
[0011] As a further technical solution, a first sliding mechanism is provided between the end of the load-bearing frame and the intermediate track, and a second sliding mechanism is also provided between the load-bearing frame and the intermediate track, so that the load-bearing frame can translate and rotate relative to the intermediate track.
[0012] As a further technical solution, the first sliding mechanism and the load-bearing frame are rotatably connected, and the load-bearing frame can rotate around the connection point with the first sliding mechanism; the second sliding mechanism and the load-bearing frame are connected by a connecting rod, and the connecting rod, the load-bearing frame, and the second sliding mechanism are all hinged.
[0013] As a further technical solution, a third rack is provided at the top of the intermediate track, and the first sliding mechanism and the second sliding mechanism both cooperate with the third rack.
[0014] As a further technical solution, the first sliding mechanism includes a second power device, which is connected to a second gear, and the second gear meshes with a third rack; the second sliding mechanism includes a third power device, which is connected to a third gear, and the third gear meshes with a third rack.
[0015] As a further technical solution, the first power unit, the second power unit, and the third power unit are all connected to the controller, and the controller communicates with the remote controller.
[0016] Secondly, the present invention also provides a car, including a luggage rack as described above, the luggage rack being fixed to the roof of the car.
[0017] The beneficial effects of the present invention are as follows:
[0018] The luggage rack of the present invention has a fixed track connected to an intermediate track, and a load-bearing frame is set between the intermediate tracks. The intermediate tracks are equipped with a first rack and a second rack of different widths. When the first rack meshes only with the first gear of the first power device, the intermediate track translates relative to the fixed track. When the first gear meshes with both the first and second racks simultaneously, since the first and second racks are located on both sides of the first gear, they are subjected to opposite forces. At this time, the intermediate track rotates relative to the fixed track, thereby allowing for preliminary adjustment of the position of the load-bearing frame.
[0019] The luggage rack of the present invention, by setting a telescopic rod, pushes the first gear, which can move the first gear and thus change the engagement relationship with the first rack and the second rack. The adjustment and operation are simple and easy to implement, making it convenient for users to adjust.
[0020] The luggage rack of this invention includes a first sliding mechanism and a second sliding mechanism between the load-bearing frame and the intermediate track. When the second and third power devices operate simultaneously in the same direction, the load-bearing frame moves along the intermediate track. When the second power device is not operating and the third power device is operating, the third gear rotates and moves along the third rack, driving the load-bearing frame to rotate around its connection with the first sliding mechanism via a connecting rod. This allows the load-bearing frame to translate and rotate relative to the intermediate track, enabling adjustment of its angle and height. This allows for stepless adjustment of the load-bearing frame's height relative to the ground, eliminating the need to cumbersomely lift and place luggage on the rack, significantly reducing manpower and mitigating the safety risks of climbing to retrieve luggage. Furthermore, after adjusting the height, the load-bearing frame can be used as a folding table, barbecue grill, etc., facilitating outdoor activities without restricting the luggage rack's position on the vehicle roof, thus fully utilizing its functionality.

[0034] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.
[0035] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0036] For ease of description, the words "up," "down," "left," and "right" appearing in this invention only indicate that they are consistent with the up, down, left, and right directions of the accompanying drawings themselves, and do not limit the structure. They are merely for the purpose of facilitating the description of this invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0037] Terminology Explanation: In this invention, terms such as “installation,” “connection,” “linking,” and “fixing” should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction relationship between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0038] In a typical embodiment of the present invention, such as Figure 1 As shown, a car roof rack is proposed, which includes a mounting bracket 1, a fixed rail 2, a middle rail 3, and a load-bearing frame 4. The mounting bracket 1 can be adapted to be installed on the car roof, and the height of the load-bearing frame can be adjusted arbitrarily.
[0039] The mounting bracket 1 is located at the bottom of the fixed track 2 and can be fixed to the roof of the car. Multiple mounting brackets 1 can be provided, and these brackets are sequentially fixed to the bottom of the fixed track 2. For example, in this embodiment, two mounting brackets 1 are provided at the bottom of each fixed track 2, and the two mounting brackets 1 are respectively fixed to the bottom of both ends of the fixed track 2. The fixed track is fixed to the mounting brackets via mounting points on the base plate. The fixed track is thus fixed to the roof of the car by installing the mounting brackets 1 on the car roof.
[0040] The fixed track 2 is set horizontally, and there are two fixed tracks 2. The two fixed tracks 2 are set parallel to each other and are set opposite each other and spaced apart.
[0041] Each fixed track 2 is connected to an intermediate track 3. Therefore, there are two intermediate tracks 3, which are parallel and spaced apart from each other. A load-bearing frame 4 is installed between the two intermediate tracks 3. The intermediate tracks 3 can be translated and rotated relative to the fixed tracks 2, and the load-bearing frame 4 can also be translated and rotated relative to the intermediate tracks 3.
[0042] A first power device 5 is fixedly installed at one end of the fixed track 2. The first power device 5 is connected to the first gear 7, and the first power device 5 drives the first gear 7 to rotate.
[0043] In this embodiment, the first power unit 5 is an electric motor.
[0044] Furthermore, a telescopic rod is provided between the first power unit 5 and the first gear 7, and the telescopic rod can drive the first gear 7 to move horizontally. The telescopic rod can be an electric telescopic rod.
[0045] The intermediate track 3 can be translated along the fixed track 2. A chute can be set in the fixed track 2, and the intermediate track 3 is placed in the chute of the fixed track 2, so that the intermediate track 3 can move along the chute of the fixed track 2.
[0046] Specifically, the intermediate track 3 has a central cavity, in which a first rack 8 is placed. The first rack 8 is arranged along the length of the intermediate track 3 and can mesh with the first gear 7. Thus, the power of the first power device 5 is transmitted to the first rack 8 via the first gear 7, causing the intermediate track 3 to translate along the fixed track 2.
[0047] A second rack 9 is also provided in the central cavity of the intermediate track 3. The second rack 9 can mesh with the first gear 7. At the same time, the first gear 7 also meshes with the first rack 8. Thus, the power of the first power device 5 is transmitted to the first rack 8 and the second rack 9 through the first gear 7, so that the intermediate track 3 rotates relative to the fixed track 2.
[0048] In a specific configuration, the first gear 7 is inserted into the central cavity of the intermediate track 3 so that it meshes with the first rack 8 and the second rack 9.
[0049] It should be noted that the widths of the first rack 8 and the second rack 9 are unequal. The first rack 8 and the second rack 9 are parallel and spaced apart. Part of the first rack 8 is opposite to the second rack 9, while another part of the first rack 8 is not opposite to the second rack 9. There is a gap between the first rack 8 and the second rack 9, and the gap is adapted to the size of the first gear 7. When the telescopic rod moves the first gear 7 to the part of the first rack 8 that is not opposite to the second rack 9, the first gear 7 only meshes with the first rack 8 and does not contact the second rack 9, so that the intermediate track 3 only translates at this time. When the telescopic rod moves the first gear 7 to the part between the first rack 8 and the second rack 9, the first gear 7 meshes with both the first rack 8 and the second rack 9. Since the first rack 8 and the second rack 9 are subjected to opposite forces, the intermediate track 3 rotates at this time.
[0050] Among them, a first sliding mechanism 6 and a second sliding mechanism 10 are provided between the load-bearing frame 4 and the intermediate track 3. The first sliding mechanism 6 is located between the end of the load-bearing frame 4 and the intermediate track 3. The first sliding mechanism 6 and the load-bearing frame 4 are rotatably connected, and the load-bearing frame 4 can rotate around the connection point with the first sliding mechanism 6. The second sliding mechanism 10 and the load-bearing frame 4 are connected by a connecting rod 11. The connecting rod 11 is hinged to both the load-bearing frame 4 and the second sliding mechanism 10. The connection point of the connecting rod 11 and the load-bearing frame 4 is adjacent to the connection end of the load-bearing frame 4 and the first sliding mechanism 6.
[0051] The first sliding mechanism 6 and the second sliding mechanism 10 are both mounted on the intermediate track 3. A third rack 12 is provided on the top of the intermediate track 3. The first sliding mechanism 6 and the second sliding mechanism 10 cooperate with the third rack 12 to realize the translation of the two sliding mechanisms relative to the intermediate track.
[0052] The first sliding mechanism 6 includes a second power device, which is connected to a second gear 13, and the second gear 13 meshes with a third rack 12.
[0053] The second sliding mechanism 10 includes a third power device, which is connected to a third gear 14, and the third gear 14 meshes with a third rack 12.
[0054] When the second power unit and the third power unit operate in the same direction, the second gear 13 and the third gear 14 rotate in the same direction, thereby causing the load-bearing frame to move along the middle track; when the second power unit is not operating and the third power unit is operating, the third gear 14 rotates and moves along the third rack 12, and drives the load-bearing frame 4 to rotate around the connection point with the first sliding mechanism 6 via the connecting rod 11.
[0055] In this embodiment, both the second and third power devices are electric motors.
[0056] The first, second, and third power units are all connected to the controller, which controls the operation of each power unit. It should be noted that the connection and control between the controller and each power unit are existing technologies and will not be elaborated upon here. Through the controller's control of each power unit, various movement scenarios can be achieved. The controller can communicate with the remote control, allowing users to freely adjust the load-bearing frame to their desired posture as needed. Furthermore, the controller can be set to a position memory function, storing different levels of user-defined postures. In subsequent use, a single button press is all it takes to reach the preset position. Users can easily reach their desired height for different scenarios such as luggage loading / unloading, picnic barbecues, or outdoor workbenches, greatly enhancing the user experience.
[0057] The working principle of this luggage rack is as follows:
[0058] Install the mounting bracket on the roof of the car, and install the fixed rail, intermediate rail, and load-bearing frame;
[0059] When the first gear 7 meshes with the first rack 8, the first power device 5 drives the first rack 8 to move through the first gear 7, and the intermediate track 3 translates along the fixed track 2.
[0060] When the first gear 7 is pushed by the telescopic rod to mesh with both the first rack 8 and the second rack 9, the intermediate track 3 rotates relative to the fixed track 2;
[0061] The second power device of the first sliding mechanism 6 and the third power device of the second sliding mechanism 10 operate in the same direction at the same time, driving the load-bearing frame 4 to move along the middle track 3.
[0062] The second power unit of the first sliding mechanism 6 is not operating, while the third power unit of the second sliding mechanism 10 is operating, driving the load-bearing frame 4 to rotate around the connection point with the first sliding mechanism 6.
[0063] Through the above actions, multiple power units can effectively realize the translation and rotation of the intermediate track relative to the fixed track, and the translation and rotation of the load-bearing frame relative to the intermediate track. This allows the height of the load-bearing frame relative to the ground to be infinitely adjusted. When picking up or putting down luggage, there is no need to lift it up and place it on the luggage rack, which greatly reduces manpower and avoids the safety risks of people climbing to pick up or put down luggage.
[0064] In another typical embodiment of the invention, a car is provided that includes a luggage rack as described above, the luggage rack being fixed to the roof of the car.
[0065] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
