Description

Technical Field

[0001] This invention belongs to the field of automotive parts technology, specifically a roof rack for electric vehicles. Background Technology

[0002] With the rapid development of the electric vehicle industry, consumers are increasingly demanding more practical and multifunctional electric vehicles. As a key component for expanding the storage space of electric vehicles, roof racks are widely used in various home and outdoor travel scenarios.

[0003] However, in actual use, the existing roof racks have poor installation and fixing flexibility. Most require manual adjustment and tightening of bolts with special tools, resulting in low adjustment efficiency. They also cannot flexibly adjust the installation position according to the weight and volume of the loaded items to match the vehicle's center of gravity, which can easily lead to safety hazards due to center of gravity shift. Furthermore, the existing equipment lubrication methods are cumbersome. The lubrication of the transmission structure often requires disassembling parts and manually adding oil, which is inconvenient and cannot achieve precise lubrication. This leads to wear and jamming of rotating and closing moving parts after long-term use, shortening the equipment's lifespan. In addition, the side-mounted lifting bracket is prone to scratching the vehicle body when unfolded, and because it lacks a synchronous limiting and locking mechanism, the overall integrity after being combined is poor.

[0004] In view of the shortcomings of the existing technology, there is an urgent need for an electric vehicle roof rack that is easy to install, has an adjustable center of gravity, is highly efficient in lubrication, is reliable in storage, and can protect the vehicle body.

The operation is efficient. At the same time, the installation position can be adjusted by sliding the slider in the long groove according to the weight and volume of the loaded items, which can flexibly adapt to the vehicle's center of gravity and avoid safety hazards caused by the center of gravity shift. Combined with the one-way locking characteristics of the ratchet mechanism, the fixing stability is further improved, and the problems of cumbersome installation and non-adjustable center of gravity of existing luggage racks are solved.

[0019] 3. This invention achieves stable storage of the luggage rack through the cooperation of the locking and closing components. The combination of the arc-shaped block and the arc-shaped perforated rubber block acts as a buffer and limit, preventing damage from collisions. The concave and convex rubber rods of the closing component abut against the vehicle body when unfolded, providing cushioning protection and preventing scratches. When folded, they align to enhance the overall structural strength. The precise cooperation between the electric lock and the U-shaped rod ensures reliable locking after folding, balancing practicality and protection, and improving the overall user experience.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1 to 13As shown, this embodiment of the invention provides a roof rack for an electric vehicle, including a base assembly 1. Two fixing components 2 are installed on both the left and right sides of the base assembly 1. Control components 3 are fixedly sleeved on the top of the two fixing components 2. Locking components 4 are installed in the middle of each of the two control components 3. Rotating components 5 are rotatably installed on the outer sides of each of the two control components 3. Lubrication components 6 are fixedly installed inside each of the two rotating components 5. Symmetrically arranged closing components 7 are rotatably installed on the outer sides of each of the two rotating components 5. Lifting components 8 are assembled on the inner side of the end of each rotating component 5 away from the control components 3. The lubrication component 6 includes an inner shell 61. A push rod 62 is inserted internally. A rectangular block 63 is fixedly installed on the right outer edge of the push rod 62. A movable rod 64 is movably inserted inside the rectangular block 63. A ring 65 is fixedly installed on the left side of the rectangular block 63. A first spring 66 is elastically connected to the left side of the ring 65. An oil reservoir 67 is fixedly installed on the left side of the push rod 62. A metal spring is installed inside the rectangular block 63, and the movable rod 64 has a limiting function inside it. The first spring 66 is sleeved on the outer edge of the push rod 62, and the end away from the ring 65 abuts against the inner wall of the inner shell 61. The oil reservoir 67 includes an outer heat insulation shell and an inner soft rubber shell. The soft rubber shell is used to store lubricating oil, and the heat insulation shell is used to isolate the influence of external temperature.

[0036] During operation, during the storage process, when the first chain 55, chain 56, and second chain 59 of the rotating assembly 5 are working, the protrusion 57 on the chain 56 exerts a leftward force on the movable rod 64 inside the rectangular block 63, thereby pushing the push rod 62 to move towards the oil reservoir 67. Its oil nozzles are respectively aligned with the hinge points of the first chain 55 and chain 56 and the second chain 59 and chain 56, achieving precise oil spraying lubrication. When the stroke of 66 is fully compressed, the pushing stops, the movable rod 64 compresses the metal spring downward, the protrusion 57 passes over the movable rod 64, and then the first spring returns to its original position, driving the push rod 62 and the oil reservoir 67 back to their initial positions, completing one lubrication operation.

[0037] Furthermore, the base assembly 1 includes a frame 11, with elongated slots 12 extending through both the left and right sides of the frame 11. A shelf 13 is fixedly installed on the top of the frame 11, and two parallel tracks 14 are fixedly installed on the bottom of the shelf 13. Dustproof strips 15 are installed in both tracks 14.

[0038] Furthermore, the fixing component 2 includes a slider 21, which is inserted into the inner side of the long groove 12. The end of the slider 21 that contacts the long groove 12 is threaded with a bolt 22. A ratchet mechanism 23 is fixedly installed on the outer edge of the bolt 22. A handle 24 is rotatably installed on the outer side of the ratchet mechanism 23. The slider 21 is locked to the inner and outer sides of the long groove 12 by the bolt 22 and the ratchet mechanism 23. The ratchet mechanism 23 consists of a pawl and a ratchet. When used with the bolt 22 and the handle 24, rotating the handle 24 can drive the bolt 22 to lock in one direction, which facilitates quick adjustment of the tightness of the bolt 22.

[0039] During operation, the center of gravity of the equipment on the top of the vehicle is determined according to the weight and volume of the items to be loaded. The slider 21 of the fixing component 2 is inserted into the long slot 12 of the frame 11. Rotating the handle 24 drives the ratchet mechanism 23 to work, which drives the bolt 22 to lock in one direction, so that the slider 21 is firmly locked on the inner and outer sides of the long slot 12. The shelf 13 on the top of the base component 1 can be used to place small items. The dustproof strip 15 in the track 14 can prevent dust from entering the interior of the track 14 and avoid affecting the sliding of subsequent parts.

[0040] Furthermore, the control component 3 includes two metal rods 31, both of which are inserted into the middle of the slider 21. Short rods 32 are fixedly connected to both the left and right ends of the two metal rods 31. Motors 33 are fixedly installed at both the front and rear ends of the short rods 32. Switches 34 are fixedly installed on the outer edge of the short rods 32. A control module 35 is fixedly installed on the inner side of the short rods 32. Arc-shaped perforated rubber blocks 36 are fixedly installed on both the front and rear sides of the control module 35.

[0041] The locking assembly 4 includes two collars 41, both of which are sleeved on the outer edge of the metal rod 31. A convex strip 42 is fixedly installed at the bottom of the two collars 41, and the convex strip 42 is slidably installed in the track 14. An electric latch 43 is fixedly installed at the top of the convex strip 42. The electric latch 43 is electrically connected to the control module 35, and the opening and closing of the electric latch 43 is controlled by the control module 35.

[0042] When the luggage rack needs to be unfolded during operation, the motor 33 is started by the switch 34. The output shaft of the motor 33 can drive the outer shell 51 of the rotating component 5 to rotate. When the outer shell 51 rotates to the open position, the arc-shaped block 53 squeezes the arc-shaped perforated rubber block 36 on the control component 3 to achieve buffering and avoid damage to the parts by collision. When the lifting component 8 is retracted, the two U-shaped rods 84 of the lifting component 8 are precisely engaged in the electric lock 43 of the locking component 4. The control module 35 controls the electric lock 43 to close, thereby locking and fixing the lifting component 8, and thus completing the storage and locking of the entire luggage rack.

[0043] Furthermore, the rotating assembly 5 includes a housing 51. The inner left side of the housing 51 is fixedly connected to the output shaft of the motor 33 of the control assembly 3. Two oil drain ports 52 and two oil filling ports 54 are sequentially opened on the bottom and back of the housing 51. An arc-shaped block 53 is fixedly installed on the back left side of the housing 51. The arc-shaped block 53 is used as a limiting element when the housing 51 is folded in and folded out. When the housing 51 is rotated to the folded or folded position, the arc-shaped block 53 will squeeze the arc-shaped perforated rubber block 36 on the control assembly 3 for buffering. A first gear 55 is rotatably installed on the left side inside the housing 51. A chain 56 is sleeved on the outer edge of the first gear 55. Two protrusions 57 are installed on the front side of the chain 56. Two tensioners 58 are installed inside the chain 56. A second gear 59 is snapped onto the other end of the chain 56. A first gear 510 is fixedly installed on the front side of the rotating shaft of the second gear 59.

[0044] The rotation shaft of the first chainring 55 is fixedly connected to the output shaft of the motor 33. The second chainring 59 is rotatably mounted inside the right side of the outer casing 51. The inner casing 61 and the oil reservoir 67 are both fixedly mounted inside the outer casing 51, and the oil nozzles of the two oil reservoirs 67 are respectively facing the hinge of the first chainring 55 and the chain 56 and the hinge of the second chainring 59 and the chain 56.

[0045] During operation, the first sprocket 55 drives the second sprocket 59 to rotate synchronously via the chain 56. The tensioner 58 on the chain 56 can adjust the tension of the chain 56 to prevent the chain 56 from becoming loose or stuck. The protrusion 57 on the chain 56 plays an auxiliary role in transmission. The rotating shaft of the second sprocket 59 drives the first gear 510 to rotate. The first gear 510 meshes with the second gear 71 of the closing assembly 7, driving the closing assembly 7 to move synchronously, so that the two symmetrically arranged closing assemblies 7 rotate and unfold with the outer shell 51.

[0046] Furthermore, the closing assembly 7 includes a second gear 71, which meshes with the first gear 510, and its rotating shaft is rotatably mounted on the front side of the right side of the outer casing 51. A circular shell 72 is fixedly mounted on the front side of the rotating shaft of the first gear 510, and a second spring 73 is mounted on the inner side of the circular shell 72. A concave rod 74 is movably mounted on the other side of the second spring 73. A convex rod 75 matching the concave rod 74 is movably mounted inside the circular shell 72 of another closing assembly 7. Both the concave rod 74 and the convex rod 75 are made of rubber and can move synchronously with the folding and unfolding of the rotating assembly 5. When the rotating assembly 5 is unfolded, the concave rod 74 and the convex rod 75 can abut against the car window and the car body, providing a buffer protection function. When the rotating assembly 5 is closed, the concave rod 74 and the convex rod 75 engage with each other, thereby improving the overall structural strength.

[0047] During operation, the concave rod 74 and convex rod 75 of the closing assembly 7 unfold synchronously with the movement, abutting against the car window and the car body, playing a buffering and protective role and preventing the car body surface from being scratched. When stored, the concave rod 74 and convex rod 75 of the closing assembly 7 engage with each other to improve the overall structural strength and prevent the parts from becoming loose after storage.

[0048] Furthermore, the lifting assembly 8 includes two fork arms 81, which are installed on the inner right side of the two housings 51 and fixedly connected to the output shaft of the second crank 59. The second crank 59 drives the fork arms 81 to rotate. Two protruding rings 82 are inserted into the top of each of the two fork arms 81. H-shaped rods 83 are fixedly installed on the inner wall of the two fork arms 81. U-shaped rods 84 are installed in the middle of the H-shaped rods 83. After the two lifting assemblies 8 are retracted under the drive of the rotating assembly 5, the two U-shaped rods 84 are just locked into the electric locking buckle 43 and locked in place by the electric locking buckle 43.

[0049] During operation, the output shaft of the second chainring 59 drives the fork arm 81 of the lifting assembly 8 to rotate, so that the fork arm 81 unfolds to a suitable angle. The protruding ring 82 at the top of the fork arm 81 can be used to limit and fix stored items. The H-shaped rod 83 and the U-shaped rod 84 cooperate to improve the structural strength of the lifting assembly 8, ensuring that it can stably lift luggage and other items and complete the unfolding action of the luggage rack.

[0050] Working principle:

[0051] When using this device, first install the base assembly 1 on the top of the vehicle. Determine the center of gravity of the device on the top of the vehicle based on the weight and volume of the items to be loaded. Insert the slider 21 of the fixing assembly 2 into the long slot 12 of the frame 11. Rotate the handle 24 to drive the ratchet mechanism 23 to work, which drives the bolt 22 to lock in one direction, so that the slider 21 is firmly locked on the inner and outer sides of the long slot 12. The shelf 13 on the top of the base assembly 1 can be used to place small items. The dustproof strip 15 in the track 14 can prevent dust from entering the interior of the track 14 and avoid affecting the sliding of subsequent parts.

[0052] When the luggage rack needs to be unfolded, the motor 33 is started by the switch 34. The output shaft of the motor 33 drives the outer shell 51 of the rotating component 5 to rotate. The arc-shaped block 53 on the left back side of the outer shell 51 plays a limiting role during the rotation. When the outer shell 51 rotates to the open position, the arc-shaped block 53 squeezes the arc-shaped perforated rubber block 36 on the control component 3 to achieve buffering and avoid damage to the parts by collision.

[0053] When the luggage rack is unfolded, the output shaft of motor 33 simultaneously drives the first chainring 55 to rotate. The first chainring 55 drives the second chainring 59 to rotate synchronously through chain 56. The tensioner 58 on chain 56 can adjust the tension of chain 56 to prevent chain 56 from becoming loose or stuck. The protrusion 57 on chain 56 plays an auxiliary transmission role. The rotating shaft of the second chainring 59 drives the first gear 510 to rotate. The first gear 510 meshes with the second gear 71 of the closing assembly 7, driving the closing assembly 7 to move synchronously. This causes the two symmetrically arranged closing assemblies 7 to rotate and unfold with the outer shell 51. During the unfolding process, the concave rod 74 and convex rod 75 of the closing assembly 7 unfold synchronously with the movement, abutting against the window and body parts, playing a buffer protection role and preventing the surface of the body from being scratched.

[0054] At the same time, the output shaft of the second chainring 59 drives the fork arm 81 of the lifting assembly 8 to rotate, so that the fork arm 81 unfolds to a suitable angle. The protruding ring 82 at the top of the fork arm 81 can be used to limit and fix the stored items. The H-shaped rod 83 and the U-shaped rod 84 cooperate to improve the structural strength of the lifting assembly 8, ensuring that it can stably lift luggage and other items and complete the unfolding action of the luggage rack.

[0055] When the luggage rack is not in use, the motor 33 is controlled by switch 34 to rotate in the reverse direction, causing the outer shell 51 of the rotating component 5 to rotate in the reverse direction. The arc-shaped block 53 again acts as a limit and buffer. When the outer shell 51 rotates to the storage position, the arc-shaped block 53 squeezes the arc-shaped perforated rubber block 36 to complete the storage positioning. At the same time, the first chain 55 drives the second chain 59 to rotate in the reverse direction through the chain 56. On the one hand, it drives the fork arm 81 of the lifting component 8 to rotate in the reverse direction, realizing the storage of the fork arm 81. On the other hand, the first gear 510 drives the second gear 71 to rotate in the reverse direction, so that the concave rod 74 and the convex rod 75 of the closing component 7 can be connected and cooperate with each other, improving the overall structural strength and preventing the parts from loosening after storage.

[0056] During storage, when the first chain 55, chain 56, and second chain 59 of the rotating assembly 5 are working, the protrusion 57 on the chain 56 exerts a leftward force on the movable rod 64 inside the rectangular block 63, thereby pushing the push rod 62 to move towards the oil reservoir 67. Its oil nozzles are respectively aligned with the hinge points of the first chain 55 and chain 56 and the second chain 59 and chain 56, achieving precise oil spraying lubrication. When the stroke of 66 is fully compressed, the pushing stops, the movable rod 64 compresses the metal spring downward, the protrusion 57 passes over the movable rod 64, and then the first spring returns to its original position, driving the push rod 62 and the oil reservoir 67 back to their initial positions, completing one lubrication operation.

[0057] When the lifting component 8 is stowed in place, the two U-shaped rods 84 of the lifting component 8 are precisely engaged in the electric lock 43 of the locking component 4. The control module 35 controls the electric lock 43 to close, thereby locking and fixing the lifting component 8, and thus completing the stowage and locking of the entire luggage rack.

[0058] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
