[0002] A car luggage rack is a device installed on the roof sheet metal for placing items. At present, more and more cars are equipped with luggage racks, but because the luggage racks protrude from the roof, when the car is driving at high speed, the high-speed airflow passing through the roof luggage rack will generate a lot of wind noise, affecting the comfort of the passengers; at the same time, the luggage rack protrudes from the roof, which also increases the projection area of ​​the car in the driving direction, increases the driving resistance of the car, and leads to increased fuel consumption when the car is driving at high speed.

[0003] Most of the currently disclosed lifting luggage racks still protrude from the roof. The main problems they solve are the inconvenience of luggage placement and luggage falling, but they cannot solve the problems of wind noise and fuel consumption caused by the protruding luggage racks. Moreover, most lifting luggage racks use hydraulic and pneumatic pressure as power sources to drive the lifting and lowering. The load-bearing weight of such fluid power sources is unstable and cannot bear a large weight. When the fluid pressure is unstable, a strict transmission ratio cannot be guaranteed, and the luggage rack is at risk of falling. The luggage rack and the heavy objects it carries fall to the roof and collide with the roof, causing deformation of the roof, bumps and noise, and other problems. Summary of the invention

[0037] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] It should be noted that in the description of the present invention, if terms indicating directions or positional relationships such as "front", "rear", "left", "right", "up", and "down" appear, they are based on the directions or positional relationships of the vehicle body and are only for the convenience of description and simplification of description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0039] Please also read Figures 1 to 18 The luggage rack provided by the present invention is now described. The luggage rack comprises a luggage rack body 2, a top cover sheet metal 1, a ceiling 3 and a lifting drive mechanism 4. The top cover sheet metal 1 is provided with an escape opening 11 for the luggage rack body 2 to be lifted and lowered; the ceiling 3 is provided below the top cover sheet metal 1, and a hidden space 5 for storing the luggage rack body 2 is formed between the ceiling 3 and the top cover sheet metal 1; the lifting drive mechanism 4 is provided in the hidden space 5.

[0040] The luggage rack provided by the present invention has a lifting drive mechanism 4 and a hidden space 5 arranged between the ceiling 3 and the top cover sheet metal 1. The luggage rack body 2 can be lifted from the escape opening 11 to the outside of the roof by the lifting drive mechanism 4, or can be stored in the hidden space 5 from the escape opening 11. When the luggage rack needs to be loaded with items, the lifting drive mechanism 4 can be used to drive the luggage rack to rise to the outside of the roof, and the loaded items (such as Figures 1 to 4 When there is no need to load on the luggage rack, the lifting drive mechanism 4 drives the luggage rack to descend from the avoidance opening 11 to the hidden space 5 under the roof sheet metal 1. When the vehicle is driving, the high-speed airflow flowing through the roof is not destroyed by the luggage rack, which can avoid the wind noise generated by the luggage rack and improve the riding comfort. It also reduces the projection area in the driving direction of the car, reduces the driving resistance, and thus reduces the fuel consumption.

[0041] Among them, the lifting drive mechanism 4 is connected to the vehicle's on-board computer through a wiring harness, and a touch button is set on the display screen of the on-board computer. The driver can independently raise and lower the luggage rack in the car, reduce the wind noise and driving resistance caused by the protruding luggage rack, improve the riding comfort, and reduce the fuel consumption of the whole vehicle.

[0042] In this embodiment, the luggage rack body 2 includes two pieces, which are arranged on the left and right sides of the roof. The corresponding top cover sheet metal 1 is provided with two avoidance openings 11 for the luggage rack body 2 to rise and fall, so that the luggage rack body 2 can be stored in the hidden space 5.

[0043] In order to ensure the consistency of the lifting and lowering of the luggage rack body 2 in the length direction, in this embodiment, two sets of driving lifting mechanisms are respectively provided for each luggage rack body 2, and the two sets of driving lifting mechanisms are dispersedly arranged at both ends of the luggage rack body 2 in the length direction.

[0044] In some embodiments, Figures 5 to 7 As shown, the luggage rack body 2 is lowered and stored in the hidden space 5, and the upper surface of the luggage rack body 2 is flush with the upper surface of the top cover sheet metal 1. After the luggage rack body 2 is stored in the hidden space 5, the upper end of the luggage rack body 2 is flush with the upper surface of the top cover sheet metal 1, which can prevent dust and rain from entering the vehicle and avoid affecting the interior of the vehicle; moreover, if the upper surface of the luggage rack body 2 is lower than the upper surface of the top cover sheet metal 1, a groove will be formed between the luggage rack body 2 and the top cover sheet metal 1, which will also cause dust and rain to accumulate, which is not conducive to the rain and dust protection of the vehicle body and also has an adverse effect on the appearance quality of the entire vehicle.

[0045] When the luggage rack body 2 rises and protrudes above the top cover sheet metal 1, the cooperation between the luggage rack body 2 and the avoidance opening 11 can still prevent dust and rain from entering the vehicle and avoid affecting the interior of the vehicle.

[0046] Optionally, a long hole 22 is provided along the length direction (ie, the front-to-back direction) of the luggage rack body 2 so that ropes can pass through the long hole 22 when bundling items on the luggage rack.

[0047] In some embodiments, Figures 8 to 15 As shown, the lifting drive mechanism 4 includes a driving motor 41, a worm 42 connected to the main shaft of the driving motor 41, a worm wheel 43 meshing with the worm 42, a screw rod 46 assembled on the worm wheel 43, and a nut 47 screwed on the screw rod 46. The lifting motor is installed on the top cover sheet metal 1 or the ceiling 3; the screw rod 46 is perpendicular to the top cover sheet metal 1, and the luggage rack body 2 is connected to the nut 47. The lifting drive mechanism 4 of this embodiment utilizes the good self-locking property and large transmission ratio of the worm gear 43 and worm shaft 42, so as to lock the raised luggage rack body 2, thereby avoiding the risk of the luggage rack body 2 falling due to the heavy weight of the items carried and the weight being pressed on the luggage rack body 2 during a long period of carrying. Through the self-locking of the worm gear 43 and worm shaft 42, compared with the luggage racks lifted by hydraulic and pneumatic means, the luggage rack has a large load-bearing capacity, and will not loosen or fall during use after it is raised. This also avoids the collision of the luggage rack with the roof when it is lowered, causing deformation of the top cover sheet metal 1, abnormal noise and other problems, thereby ensuring driving safety.

[0048] In this embodiment, the worm 42 can be connected to the main shaft of the driving motor 41 through a spline sleeve and rotate synchronously with the main shaft. The worm 42 drives the worm wheel 43 to rotate, and the worm wheel 43 drives the screw rod 46 to rotate. The rotation of the screw rod 46 causes the nut 47 to move linearly along the screw rod 46, thereby driving the luggage rack body 2 to rise and fall.

[0049] The driving motor 41 is a motor capable of forward and reverse motion. For example, when the driving motor 41 rotates clockwise, it drives the luggage rack body 2 to rise, and when the driving motor 41 rotates counterclockwise, it drives the luggage rack body 2 to descend.

[0050] Regarding the fixing position of the driving motor 41, it can be fixed on the lower surface of the top cover sheet metal 1, or it can be fixed on the ceiling 3, such as Figures 8 to 15 As shown, the present embodiment chooses to fix the driving motor 41 on the roof sheet metal 1. The weight of the driving motor 41 is not directly applied to the ceiling 3, but is transmitted to the vehicle body through the roof sheet metal 1. This is because the roof sheet metal 1 is generally high in strength, while the strength of the ceiling 3 is relatively low. The driving motor 41 bears the weight through the roof sheet metal 1 and then distributes it to the vehicle body. On the one hand, it ensures that the installation position of the driving motor 41 will not be deformed, thereby ensuring the position reliability of the driving motor 41, and further ensuring the position accuracy of the rising and falling of the luggage rack body 2; on the other hand, it avoids affecting the ceiling 3 and the space inside the vehicle.

[0051] Optionally, the nut 47 and the screw rod 46 can be matched with a ball screw, or a suitable ball screw can be selected to replace the nut 47 and the screw rod 46. The use of a ball screw can make the movement of the lifting luggage rack smoother and more precise, with less noise, and reduce the impact on the quietness of the vehicle interior.

[0052] As another embodiment of the lifting drive mechanism 4, the lifting drive mechanism 4 can directly adopt the lifting method of the screw rod 46 and the nut 47. Specifically, the screw rod 46 is directly connected to the main shaft of the drive motor 41, and the main shaft of the drive motor 41 is perpendicular to the top cover sheet metal 1. Doing so requires increasing the height of the hidden space 5, which will squeeze the space inside the vehicle.

[0053] In this embodiment, the top cover sheet metal 1 is selected to bear the weight of the drive motor 41, specifically, as Figures 8 to 15 As shown, a mounting plate 15 is fixedly provided on the lower surface of the top cover sheet metal 1, the mounting plate 15 is close to the avoidance opening 11, and the driving motor 41 is fixedly provided on a motor fixing plate 16 on the mounting plate 15 away from the lower end of the top cover sheet metal 1; a support plate 17 is fixedly provided on the mounting plate 15, and one end of the worm 42 is rotatably connected to the support plate 17.

[0054] The mounting plate 15 is a long strip, which is vertically fixed on the top cover sheet metal 1. The side of the mounting plate 15 facing the avoidance opening 11 is parallel to the lifting direction of the luggage rack body 2, providing structural support for the installation of the screw 46. The support plate 17 is used to provide support for the rotation of the worm 42, wherein the worm 42 can be rotatably connected to the support plate 17 through a bearing embedded in the support plate 17.

[0055] In some embodiments, Figures 8 to 15 As shown, two support blocks 45 are also provided on the mounting plate 15, and the two ends of the screw rod 46 are rotatably connected to the support blocks 45. Among them, the two ends of the screw rod 46 are rotatably connected to the support blocks 45 through bearings installed in the support blocks 45.

[0056] In some embodiments, Figures 8 to 14 As shown, the screw rod 46 is connected to the worm gear 43 through the coupling 44. Specifically, the coupling 44 is a safety coupling 44 (also called a torque limiter, torque limiter, safety clutch), which is a component that connects the driving machine and the working machine. Its main function is overload protection. When the required torque exceeds the set value due to overload or mechanical failure, the torque limiter limits the torque transmitted by the transmission system in the form of slipping, and automatically restores the connection when the overload disappears. In this way, mechanical damage is prevented and losses are avoided. Only a mechanical torque limiter can quickly cut off the connection between the motor and the main shaft, thereby eliminating the destructive effect of inertia.

[0057] In this embodiment, the worm gear 43 is connected to the screw rod 46 via the safety coupling 44. The safety coupling 44 can prevent overload. When the load on the upper end of the screw rod 46 exceeds the load protected by the coupling 44, the coupling 44 and the screw rod 46 are disengaged, thereby protecting the drive motor 41.

[0058] The action process based on this coupling 44 is as follows: when the driving motor 41 rotates clockwise, it drives the worm 42 to rotate, and then drives the worm wheel 43 to rotate, through the coupling 44, drives the screw rod 46 to rotate, and when the screw rod 46 rotates, it will drive the moving block to move upward, thereby driving the luggage rack body 2 to move upward, so that the luggage rack body 2 rises out of the top cover sheet metal 1; if the driving motor 41 rotates counterclockwise, on the contrary, the luggage rack body 2 moves downward and is hidden between the top cover sheet metal 1 and the ceiling 3.

[0059] In some embodiments, Figures 8 to 15 As shown, a guide plate 13 is provided on the top cover sheet metal 1, and the guide plate 13 is close to the avoidance opening 11. When the luggage rack body 2 is raised or lowered, the side surface contacts the guide plate 13. The guide plate 13 has a guiding and limiting function for the lifting and lowering of the luggage rack body 2, ensuring that the luggage rack body 2 is lifted up and down in the vertical direction.

[0060] Optionally, guide plates 13 are provided at both the front and rear ends of the luggage rack body 2 to ensure the consistency of the lifting and lowering of the luggage rack body 2 in the front and rear directions, so as to avoid the problem that the luggage rack body 2 is deflected and cannot pass smoothly through the avoidance opening 11.

[0061] In some embodiments, Figures 8 to 15 As shown, a guide block 21 is provided on the side of the luggage rack body 2, and a guide groove 14 is provided on the guide plate 13 to slide with the guide block 21. Specifically, the outer side surfaces of the front and rear ends of the luggage rack body 2 are provided with guide blocks 21 protruding in the left direction or the right direction, and the guide blocks 21 extend into the guide groove 14 and rise and fall along the guide groove 14 with the rise and fall of the luggage rack body 2, so as to ensure that the luggage rack body 2 can move straightly upward and downward along the guide groove 14, and ensure the smooth rise and retraction of the luggage rack body 2.

[0062] Optionally, the guide plate 13 can be arranged on the left side or the right side of the avoidance opening 11, or the guide plate 13 and the lifting drive mechanism 4 are arranged on the same side of the avoidance opening 11, or the guide plate 13 and the lifting drive mechanism 4 are arranged on both sides of the avoidance opening 11 respectively.

[0063] In order to improve the supporting strength of the top cover sheet metal 1 and the luggage rack body 2, in some embodiments, a supporting structure is further provided between the top cover sheet metal 1 and the ceiling 3, such as Figures 8 to 17 shown.

[0064] like Figures 8 to 17As shown, as an optional implementation of the support structure, the support structure includes at least one support column 31 arranged on the lower surface of the top cover sheet metal 1, and also includes a support sleeve 12 that is cooperatively arranged on the ceiling 3, and the support column 31 is sleeved in the support sleeve 12.

[0065] Optionally, the support column 31 is arranged on the ceiling 3, and the support sleeve 12 is arranged on the top cover sheet metal 1. Multiple rows of support columns 31 can be arranged, and multiple rows of support sleeves 12 are arranged accordingly.

[0066] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0067] Based on the same inventive concept, an embodiment of the present application also provides a vehicle, characterized in that the luggage rack.

[0068] In the vehicle provided by the present invention, when the luggage rack is not needed, the luggage rack can be hidden in the hidden space 5 below the top cover sheet metal 1, which can not only reduce wind noise, but also save energy consumption and improve the value of the entire vehicle.

[0069] When the luggage rack needs to be used to load goods, the driver controls the driving motor 41 to rotate clockwise, driving the worm 42 to rotate, and then driving the worm wheel 43 to rotate, passing through the coupling 44, driving the screw 46 to rotate, and when the screw 46 rotates, it will drive the moving block to move upward, thereby driving the luggage rack to move upward, so that the luggage rack rises out of the top cover sheet metal 1 and loads the goods. When the luggage rack is not needed to load items, the driving motor 41 rotates counterclockwise, driving the worm 42 to rotate counterclockwise, and then driving the worm wheel 43 to rotate counterclockwise, passing through the coupling 44, driving the screw 46 to rotate counterclockwise, and when the screw 46 rotates counterclockwise, it will drive the moving block to move downward, thereby driving the luggage rack to move downward, so that the upper surface of the luggage rack is flush with the upper surface of the top cover sheet metal 1.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
