Description

Technical Field

[0001] This invention relates to the field of luggage technology, and more particularly to a roof luggage box. Background Technology

[0002] A roof box is a type of vehicle storage box that is installed on the roof of a car using mounting brackets and auxiliary accessories. It provides extra storage space besides the trunk, allowing users to carry more luggage and items during road trips. Roof boxes typically have waterproof and UV-resistant properties, so they can affect the interior temperature of the vehicle.

[0003] However, to avoid affecting vehicle driving safety and excessively increasing vehicle fuel consumption, the size of the roof box is generally smaller than the size of the car roof. As a result, the area covered by the roof box is smaller, and its sun protection area is smaller, which cannot guarantee a good cooling effect on the car interior. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a roof box that effectively increases the sun protection area of ​​the roof, improves the sun protection effect on the car roof, and enhances the cooling effect inside the vehicle.

[0005] To solve the above-mentioned technical problems, the present invention provides a roof box, including a support plate for connecting to the roof of a vehicle, a rotating assembly disposed on the support plate, a box body connected to the rotating assembly, and a sunshade assembly disposed on the long side of the box body;

[0006] The rotating assembly includes a bottom shell, a turntable, and a connecting plate. The bottom shell is fixedly installed on the support plate, and the turntable is rotatably connected to the bottom shell. A drive group is formed on the side of the turntable, and the drive group is used to drive the turntable to rotate relative to the bottom shell by a preset angle. The connecting plate is connected to the top of the turntable, and the housing body is installed on the side of the connecting plate opposite to the turntable.

[0007] The long side of the box body is formed with a sunshade hole, and the extended end of the sunshade awning assembly extends out of the sunshade hole or retracts into the sunshade hole in a predetermined direction, the predetermined direction being perpendicular to the length direction of the sunshade hole.

[0008] The width of the extended end of the awning assembly is greater than the width of the short side of the main body of the box.

[0009] The drive assembly includes a drive motor and a worm gear, wherein the worm gear is rotatably connected to the output shaft of the drive motor;

[0010] The turntable has a first arc-shaped rack on its side that can mesh with the worm gear. A specific angle is formed between the first end of the first arc-shaped rack and the second end of the first arc-shaped rack. The specific angle is greater than or equal to the preset angle.

[0011] The connecting plate has a stop pin formed on its edge, and the end of the stop pin opposite to the connecting plate has two stop protrusions.

[0012] The support plate has a forward stop block and a reverse stop block, both of which are located directly below the edge of the connecting plate. The forward stop block has a first stop groove, and the reverse stop block has a second stop groove. The first stop groove is oriented in the width direction of the support plate, and the second stop groove is oriented in the length direction of the support plate.

[0013] The connecting plate is rotatably connected to the bearing plate via a plurality of support rollers, and a vibration damping pad is formed on the side of the bearing plate facing the connecting plate. The surfaces of the support rollers and the vibration damping pad can roll relative to each other.

[0014] The awning assembly includes a first driving member, a roller, a sunshade cloth, and a telescopic member. The first driving member is disposed on the inner wall of the sunshade hole. The roller is rotatably connected to the output shaft of the first driving member. The first end of the sunshade cloth is wound around the outer wall of the roller.

[0015] The first end of the telescopic component is connected to the inner wall of the sunshade hole, the second end of the telescopic component extends or retracts along the predetermined direction, and the second end of the sunshade cloth is connected to the second end of the telescopic component.

[0016] The telescopic component includes a first curved arm and a second curved arm that are hinged to each other. The first end of the first curved arm is rotatably connected to the inner wall of the sunshade hole, and the second end of the second curved arm is rotatably connected to the second end of the sunshade cloth. An elastic element is provided at the first end of the first curved arm, and the elastic element is used to apply tension to the first curved arm and the sunshade cloth.

[0017] The top of the box body is rotatably connected to a door, and an automatic door opening assembly is provided inside the box body. The automatic door opening assembly is used to drive the door to open from the top of the box body or close at the top of the box body.

[0018] The automatic door opening assembly includes a second drive member and a second arc-shaped rack. The output shaft of the second drive member is provided with a drive gear, which meshes with the second arc-shaped rack. The end of the second arc-shaped rack away from the drive gear is connected to the door body.

[0019] The main body of the box is made of lightweight material.

[0020] The rear of the box body is provided with at least two sets of brake lights, and each set of brake lights is provided with multiple light source components at intervals.

[0021] The front of the housing is provided with a vehicle speed detection device, which is electrically connected to at least two sets of brake lights.

[0022] The housing contains a controller, and the vehicle speed detection device and each set of brake lights are electrically and / or signal-connected to the controller. The controller is connected to a pressure sensor, which is used to detect the braking force of the brake pedal.

[0023] Implementing this invention has the following beneficial effects:

[0024] According to an embodiment of the present invention, the roof box can be mounted on the vehicle roof via a mounting structure such as a fixing bracket and auxiliary accessories. In this case, the long side of the roof box faces the side of the vehicle, and the short side faces the front or side of the vehicle. A drive unit rotates the turntable by a preset angle, correspondingly rotating the connecting plate and the box body by a corresponding angle. This causes the sunshade assembly at the long side of the box body to rotate a certain angle from the side of the vehicle. When the protruding end of the sunshade assembly extends from the sunshade hole, since the width of the protruding end is greater than the width of the short side of the box body, the area that the protruding end of the sunshade assembly can cover on the vehicle roof is increased. This effectively improves the sun protection effect on the car roof, blocking direct sunlight from entering the vehicle interior and effectively preventing excessively high interior temperatures caused by sun exposure when the vehicle is parked, thus improving the user's riding comfort.

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0040] The roof box provided by this invention can effectively increase the sun protection area of ​​the roof, improve the sun protection effect on the car roof and the cooling effect inside the car.

[0041] In one specific embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the roof box includes a support plate 1 for connecting to the roof of the vehicle, a rotating assembly 2 disposed on the support plate 1, a box body 3 connected to the rotating assembly 2, and a sunshade assembly 4 disposed on the long side of the box body 3.

[0042] Among them, such as Figures 3 to 6As shown, the rotating assembly 2 includes a base shell 21, a turntable 22, and a connecting plate 23. The base shell 21 is fixedly mounted on the support plate 1, and the turntable 22 is rotatably connected to the base shell 21. A drive assembly 24 is formed on the side of the turntable 22, which is used to drive the turntable 22 to rotate relative to the base shell 21 by a preset angle. The connecting plate 23 is connected to the top of the turntable 22, and the housing body 3 is mounted on the side of the connecting plate 23 away from the turntable 22.

[0043] The long side of the box body 3 has a sunshade hole 31. The extended end of the sunshade awning assembly 4 extends out of the sunshade hole 31 or retracts into the sunshade hole 31 in a predetermined direction. The predetermined direction is perpendicular to the length direction of the sunshade hole 31. The width of the extended end of the sunshade awning assembly 4 is greater than the width of the short side of the box body 3.

[0044] According to an embodiment of the present invention, the roof box, with its support plate 1 mounted on the vehicle roof via a mounting structure such as a fixing bracket and auxiliary accessories, has its long side facing the side of the vehicle. The drive unit 24 drives the turntable 22 to rotate by a preset angle, correspondingly rotating the connecting plate 23 and the box body 3 by a corresponding angle. This causes the sunshade assembly 4 at the long side of the box body 3 to rotate a certain angle from the side of the vehicle. When the protruding end of the sunshade assembly 4 extends from the sunshade hole 31, since the width of the protruding end of the sunshade assembly 4 is greater than the width of the short side of the box body 3, the area that the protruding end of the sunshade assembly 4 can cover on the vehicle roof increases. This effectively improves the sun protection effect on the car roof, blocking direct sunlight from entering the vehicle interior and effectively preventing excessively high interior temperatures caused by sun exposure when the vehicle is parked, thus improving the user's riding comfort.

[0045] Furthermore, when the long side of the roof box faces the side of the vehicle, if the extended end of the awning assembly 4 extends along the length direction perpendicular to the sunshade hole 31, the awning assembly 4 can provide an additional sunshade rest area outside the vehicle on the side of the vehicle. Users can camp or rest in the additional sunshade rest area outside the vehicle, thus enabling the roof box to have a camping function.

[0046] Therefore, in this embodiment, the rotating component 2 drives the box body 3 to rotate, so that the sunshade component 4 on the long side of the box body 3 can extend in different directions of the vehicle according to actual needs. Thus, by using the sunshade components 4 extending in different directions, the roof luggage box can have camping and sunshade functions, effectively meeting the different usage needs of users and improving the user experience of the roof luggage box and the vehicle.

[0047] It should be noted that the width of the short side of the box body 3 is preferably equal to the width of the top of the vehicle roof. In this embodiment, the preset angle is preferably 90°, that is, the long side of the box body 3 can be rotated from the side of the vehicle to the front of the vehicle, so that when the extended end of the sunshade assembly 4 is extended, it can directly provide sun protection to the front of the vehicle.

[0048] Furthermore, since the width of the extended end of the awning assembly 4 is greater than the width of the short side of the body 3, meaning the width of the extended end of the awning assembly 4 is greater than the width of the roof, the extended end of the awning assembly 4 can completely cover the top of the vehicle when extended, further ensuring the sunshade and cooling effect of the awning assembly 4 on the vehicle below. When the awning assembly 4 is not needed to shade the vehicle, the body 3 can be rotated so that the long side of the body 3 returns to the side of the vehicle, so that the body 3 does not protrude outward from the side of the vehicle, ensuring the aesthetics of the vehicle roof while avoiding the body 3 increasing the drag when the vehicle is in motion.

[0049] It should also be noted that, since the front of most vehicles is typically longer and more complex than the rear, a set of sunshade components 4 is arranged on each of the two long sides of the body 3 to provide adequate sun protection for the front of the vehicle. One set of sunshade components 4 faces the front of the vehicle after the body 3 rotates, and the other set faces the front of the vehicle after the body 3 rotates. The protruding end of one set of sunshade components 4 has a length of L1, and the protruding end of the other set has a length of L2. L1 is preferably greater than L2 to ensure that the coverage area of ​​the sunshade components 4 on the front of the vehicle is greater than the coverage area on the rear of the vehicle, ensuring that the front of the vehicle is adequately protected.

[0050] Preferably, the length L1 of the extended end of the sunshade assembly 4 located at the front of the vehicle is 1.5m, and the length L2 of the extended end of the sunshade assembly 4 located at the rear of the vehicle is 1.2m.

[0051] In this embodiment, as Figure 5 As shown, the drive assembly 24 includes a drive motor 241 and a worm gear 242, with the worm gear 242 rotatably connected to the output shaft of the drive motor 241. A first arc-shaped rack 243 is formed on the side of the turntable 22, which meshes with the worm gear 242. The drive motor 241 drives the worm gear 242 to rotate, causing the teeth of the arc-shaped rack to move in conjunction with the worm gear 242, thereby driving the turntable 22 to rotate.

[0052] In actual use, by controlling the rotation angle and rotation speed of the output shaft of the drive motor 241, the rotation angle of the turntable 22 can be controlled to reach the preset angle, thereby ensuring that the extension direction of the sunshade assembly 4 can face the actual required direction and ensuring that the box body 3 rotates smoothly.

[0053] A specific angle is formed between the first end and the second end of the first arc-shaped rack 243. This specific angle is greater than or equal to a preset angle to ensure that when the drive motor 241 drives the turntable 22 to rotate via the first arc-shaped rack 243, the length of the first arc-shaped rack 243 can meet the rotation angle required for the rotation of the housing body 3. Preferably, the specific angle between the first end and the second end of the first arc-shaped rack 243 is equal to the preset angle of rotation of the turntable 22. For example, when the preset angle is 90°, the specific angle between the first end and the second end of the first arc-shaped rack 243 is 90°, that is, the first arc-shaped rack 243 is a quarter-sector rack.

[0054] Of course, the specific angle between the first end and the second end of the first arc-shaped rack 243 can also be greater than the rotation angle required by the turntable 22, so as to ensure that the worm gear 242 and the first arc-shaped rack 243 always remain engaged during the process of the drive motor 241 driving the first arc-shaped rack 243 to rotate, and to ensure that the drive motor 241 can drive the housing body 3 to rotate back to the original installation position.

[0055] It should be noted that the drive unit 24 is not limited to the method of the drive motor 241 driving the worm gear 242 to rotate and drive the arc rack to move. It can also be that the drive motor 241 drives the gear set structure to rotate, and the driven shaft in the gear set drives the turntable 22 to rotate, so as to drive the roof box body to rotate by a predetermined angle; or the roof box body can be driven to rotate by hydraulic drive or other drive methods.

[0056] It should also be noted that a controller (not shown in the figure) can be installed inside the housing 3. The controller is electrically connected to the drive motor 241 and is also signal-connected to an external remote control so that the external remote control can send control signals to the controller to drive the drive motor 241 to start or stop, and to control the operating speed of the drive motor 241.

[0057] Of course, the controller can also be directly connected to the vehicle's internal control system signal. Users can directly press the button connected to the vehicle's control system to control the rotation of the box body 3. In addition, the roof box can also be equipped with a luggage box remote control, and the controller can be directly connected to the luggage box remote control signal.

[0058] In this embodiment, as Figures 3 to 6As shown, a stop pin 231 is formed on the edge of the connecting plate 23, and two stop protrusions 232 are formed on the end of the stop pin 231 facing away from the connecting plate 23. The bearing plate 1 is formed with a forward stop block 11 and a reverse stop block 12, both of which are located directly below the edge of the connecting plate 23. The forward stop block 11 is formed with a first stop groove 111, and the reverse stop block 12 is formed with a second stop groove 121. The first stop groove 111 is oriented in the width direction of the bearing plate 1, and the second stop groove 121 is oriented in the length direction of the bearing plate 1. Therefore, during the rotation of the connecting plate 23 driven by the turntable 22, the rotation position of the connecting plate 23 can be limited by the forward stop block 11 and the reverse stop block 12, ensuring that after the connecting plate 23 rotates, the long side of the housing body 3 can stably face the front or side of the vehicle.

[0059] Specifically, when the long side of the box body 3 faces the side of the vehicle, the stop pin 231 is inserted into the second stop groove 121 of the reverse stop block 12, facing the stop protrusion 232 of the reverse stop block 12; while when the turntable 22 rotates clockwise, the stop pin 231 rotates from the reverse stop block 12 to the forward stop block 11, and after the box body 3 rotates by a preset angle, the stop pin 231 is inserted into the first stop groove 111 of the forward stop block 11, thereby ensuring that the long side of the box body 3 rotates... The sunshade 43 can then face the front of the vehicle to provide sun protection for the front of the vehicle. When the turntable 22 rotates counterclockwise, the stop pin 231 rotates from the forward stop block 11 to the reverse stop block 12. After the box body 3 rotates at a preset angle, the stop pin 231 is inserted into the second stop groove 121 of the reverse stop block 12 towards the stop protrusion 232 of the reverse stop block 12. This ensures that the long side of the box body 3 can face the side of the vehicle after rotation, so as to provide camping function for the sunshade 43 on the side of the vehicle.

[0060] It should also be noted here that, as Figure 4 As shown, the connecting plate 23 is made of aluminum, and a weight-reducing groove 234 is formed in the connecting plate 23 to reduce the overall weight of the connecting plate 23.

[0061] In this embodiment, the connecting plate 23 is circular. Since the luggage compartment body generally has a certain weight, in order to ensure that the roof luggage compartment rotating component can support the roof luggage compartment body, the diameter of the connecting plate 23 is preferably equal to the width of the compartment body 3.

[0062] To further ensure that the connecting plate 23 can support the housing body 3, such as Figure 3 and Figure 4As shown, multiple support rollers 233 are rotatably connected between the edge of the connecting plate 23 and the bearing plate 1, providing support for the edge of the connecting plate 23 and ensuring the stability of the connecting plate 23 in supporting the housing body 3. A vibration damping pad 13 is formed on the side of the bearing plate 1 facing the connecting plate 23. The surfaces of the support rollers 233 and the vibration damping pad 13 can roll relative to each other. This ensures the rotational stability of the connecting plate 23 and the housing body 3 while reducing the relative vibration between the support rollers 233 and the bearing plate 1 through the vibration damping pad, thereby reducing rolling noise during rolling. Preferably, the vibration damping pad 13 is made of rubber or silicone.

[0063] In this embodiment, as Figures 7 to 10 As shown, the awning assembly 4 includes a first drive member 41, a roller 42, a shading cloth 43, and a telescopic member 44. The first drive member 41 is disposed on the inner wall surface of the shading hole 31. The roller 42 is rotatably connected to the output shaft of the first drive member 41. The first end of the shading cloth 43 is wound around the outer wall surface of the roller 42. The first end of the telescopic member 44 is connected to the inner wall of the shading hole 31, and the second end of the telescopic member 44 extends or retracts in a predetermined direction. The second end of the shading cloth 43 is connected to the second end of the telescopic member 44.

[0064] Understandably, when a user needs to protect their car from the sun or needs to rest outside the vehicle, the first drive unit 41 can be activated. The output shaft of the first drive unit 41 drives the drum 42 to rotate, releasing the sunshade cloth 43 wrapped around the outer wall of the drum 42. The second end of the telescopic member 44 extends, causing the sunshade cloth 43 to extend in a direction perpendicular to the sunshade hole 31, so that the sunshade cloth 43 can be unfolded outside the body 3. This makes it easy to lay the sunshade cloth 43 flat to cover the top of the vehicle to achieve sun protection for the vehicle top; or it can create an additional sunshade rest area under the unfolded sunshade cloth 43 for users to rest or camp.

[0065] Specifically, the first driving component 41 can be a motor, and the motor housing is installed inside the housing body 3 by fasteners such as brackets and bolts. An interference fit is formed between the inner wall surface of the drum 42 and the motor output shaft to achieve a tight fit between the drum 42 and the motor output shaft, ensuring that the drum 42 can rotate stably under the drive of the drive shaft.

[0066] It should be noted that, in order to ensure the sunshade effect on the vehicle under the roof trunk and to guarantee the sunshade and heat preservation effect on the vehicle below, the width of the sunshade cloth 43 is greater than the width of the short side of the trunk body 3, that is, the width of the sunshade cloth 43 is greater than the width of the vehicle roof.

[0067] Specifically, such as Figure 9 and Figure 10As shown, the telescopic component 44 includes a first curved arm 441 and a second curved arm 442 that are hinged to each other. The first end of the first curved arm 441 is rotatably connected to the inner wall of the sunshade hole 31, and the second end of the second curved arm 442 is rotatably connected to the second end of the sunshade cloth 43. The first curved arm 441 and the second curved arm 442 gradually unfold when the sunshade cloth 43 is extended and gradually retract when the sunshade cloth 43 is retracted. The operation of the drive component ensures that the sunshade can be flexibly unfolded and retracted, and ensures that the unfolding and retraction of the sunshade is smooth, so as to avoid affecting the user's use.

[0068] An elastic element 443 is provided at the first end of the first curved arm 441. The elastic element 443 is used to apply tension to the first curved arm 441 and the sunshade cloth 43, so that when the sunshade cloth 43 extends or retracts, the elastic element 443 further ensures that the sunshade cloth 43 can have a certain tension, and ensures that the sunshade cloth 43 can be smoothly unfolded or retracted.

[0069] Specifically, such as Figure 10 As shown, the elastic element 443 is a tension spring. One end of the tension spring is connected to the first end of the first curved arm 441, and the second end of the second curved arm 442 is connected to a pull rope 444. The pull rope 444 passes around the first end of the second curved arm 442 and is connected to the other end of the tension spring. When the sunshade 43 is fully unfolded, the tension spring is in a stretched state, so as to store or release elastic potential energy using the tension spring and pull rope 444 between the first curved arm 441 and the second curved arm 442, ensuring that tension can be applied to the sunshade 43.

[0070] When the sunshade 43 is not unfolded, the second curved arm 442 stretches the tension spring via the pull rope 444, and the tension spring has its longest extension length, meaning that the elastic potential energy stored in the tension spring is at its maximum. When the first curved arm 441 and the second curved arm 442 unfold, the extension length of the tension spring gradually decreases, and the elastic force released by the tension spring acts on the sunshade 43 through the first curved arm 441 and the second curved arm 442, ensuring that the sunshade 43 remains taut throughout its unfolding process. Even when the sunshade 43 is fully unfolded, the elastic force of the tension spring still ensures that the sunshade 43 remains taut, thereby improving... It provides a good sunshade effect; when the first curved arm 441 and the second curved arm 442 are retracted, the pull rope 444 re-stretches the tension spring, so that the tension spring re-stores elastic potential energy. At the same time, the first curved arm 441 and the second curved arm 442 are still subjected to the outward elastic force applied by the tension spring. Under the simultaneous action of the first curved arm 441 and the second curved arm 442 on both sides, the sunshade cloth 43 is still subjected to tension force on both sides of the sunshade cloth 43 when it is retracted, so that the sunshade cloth 43 can also remain taut when it is retracted, effectively reducing the wrinkles caused by the slack when the sunshade cloth 43 is retracted, and avoiding the deformation of the sunshade cloth 43.

[0071] It should be noted that during the extension of the sunshade 43, the first curved arm 441 and the second curved arm 442 provide support for the sunshade 43. When the sunshade 43 is fully extended, the first curved arm 441 and the second curved arm 442 form a certain angle to increase the support area of ​​the first curved arm 441 and the second curved arm 442 on the sunshade 43, distribute the load on the sunshade 43, and make the sunshade 43 more stable and less prone to deformation under the external force of wind pressure.

[0072] Furthermore, a limiting block (not shown in the figure) is provided on the inner wall of the sunshade hole 31. The limiting block is a square protrusion formed on the inner wall of the sunshade. The bottom surface of the limiting block is flush with the top surface of the sunshade hole 31, and the bottom surface of the limiting block abuts against the top surface of the sunshade cloth 43. The limiting block restricts the extension direction of the sunshade cloth 43, ensuring that after the sunshade cloth 43 extends out of the sunshade hole 31, it accurately covers the area that needs sunshade, thus ensuring the sunshade effect of the sunshade cloth 43. At the same time, when the sunshade cloth 43 is retracted, the limiting block can be used to ensure that the sunshade cloth 43 can be neatly wound on the roll 42 without leaving gaps or wrinkles, thus avoiding affecting the subsequent extension and unfolding of the sunshade cloth 43.

[0073] In this embodiment, the second end of the sunshade cloth 43 is connected to a front-end shielding shell (not shown in the figure), the size of which is equal to the size of the sunshade hole 31. When the sunshade cloth 43 is retracted, the side of the front-end shielding shell facing away from the sunshade cloth 43 is flush with the side of the box body 3, so that the front-end shielding shell can cover the sunshade hole 31 after the sunshade cloth 43 is retracted, preventing the sunshade hole 31 from being exposed and ensuring the overall aesthetic appearance of the box body 3.

[0074] In another embodiment, to further increase the coverage area of ​​the additional rest area under the sunshade 43, a secondary sunshade assembly can be provided inside the front shielding shell. The structure of the secondary sunshade assembly is preferably the same as that of the sunshade assembly 4 located in the sunshade hole 31, also including a drive unit, a roller 42, a sunshade 43, and a telescopic member 44. Therefore, when it is necessary to increase the coverage area of ​​the additional rest area, the secondary roller can be driven to rotate, releasing the secondary sunshade 43, and the secondary telescopic member can be used to extend the secondary sunshade 43 further, thereby increasing the sunshade space under the sunshade 43 and further meeting the user's requirements for the size of the sunshade rest area.

[0075] The connection method between the components in the secondary awning assembly is the same as that of the awning assembly 4 located in the awning hole 31, and will not be described in detail here.

[0076] In this embodiment, as Figure 1 , Figure 2 and Figure 12As shown, a door 32 is rotatably connected to the top of the box body 3, and an automatic door opening assembly 33 is provided inside the box body 3. The automatic door opening assembly 33 is used to drive the door 32 to open from the top of the box body 3 or close at the top of the box body 3.

[0077] Among them, such as Figure 12 As shown, the automatic door opening assembly 33 includes a second drive member 331 and a second arc-shaped rack 332. The output shaft of the second drive member 331 is equipped with a transmission gear set, which meshes with the second arc-shaped rack 332. The end of the second arc-shaped rack 332 away from the drive gear is connected to the door body 32. The rotation of the output shaft of the second drive member 331 drives the transmission gear set, thereby causing the second arc-shaped rack 332 to operate in conjunction with the transmission gear set, thus opening or closing the door body 32 and achieving automatic opening or closing of the suitcase.

[0078] Specifically, the two ends of the second arc-shaped rack 332 form an included angle. Preferably, this included angle exceeds the actual opening angle required by the door 32 by 5°-10°. For example, when the actual opening angle required by the door 32 is 45°, the included angle between the first and second ends of the second arc-shaped rack 332 is 50° to 55°, ensuring that the distance the drive gear drives the second rack to move is sufficient to meet the actual opening angle required by the door 32. More preferably, the included angle between the two ends of the second arc-shaped rack 332 exceeds the actual opening angle required by the door 32 by 5°.

[0079] Furthermore, such as Figure 11 As shown, a guide block 34 is formed inside the door body 32. The guide block 34 has a guide hole that extends along the opening and closing direction of the door body 32. An arc-shaped guide member 35 is slidably inserted into the guide hole of the guide block 34. The end of the arc-shaped guide member 35 away from the guide block 34 is fixedly connected to the door body 32. In order to provide guidance for the door body 32 to open or close during the process of the automatic door opening assembly 33 driving the door body 32 to open or close, the guide member can be used to ensure that the door body 32 can move along a specific path when opening or closing, and ensure the stability of the door body 32 when opening and closing.

[0080] To reduce the overall weight of the roof box, the box body 3 is made of lightweight materials. These materials can be plastic or aluminum alloy, ensuring the box body 3 can withstand a certain amount of weight while reducing the overall weight of the box body 3. This reduces the vehicle's extra weight, effectively lowers fuel consumption, and improves driving stability.

[0081] In addition, to reduce wind resistance caused by the roof box while the vehicle is in motion and to improve the vehicle's fuel economy and driving stability, the shell of the box body 3 preferably adopts a streamlined structure.

[0082] In this embodiment, as Figures 12 to 14 As shown, at least two sets of brake light groups 51 are arranged at the rear of the body 3, and multiple light source components 511 are arranged at intervals within each set of brake light groups 51. A vehicle speed detection component 52 is provided at the front of the body 3, and the vehicle speed detection component 52 is electrically connected to the at least two sets of brake light groups 51. The vehicle speed detection component 52 is used to detect the vehicle's speed and, according to changes in the vehicle's speed, controls one set of brake light groups 51 to illuminate or controls at least two sets of brake light groups 51 to illuminate and flash. This provides different braking warning reminders to following vehicles from the roof position of the car, effectively improving the warning effect of the car's brake light system on following vehicles. The drivers of following vehicles can more intuitively understand the braking intention and urgency of the vehicle in front, thereby reacting in advance, avoiding rear-end collisions, and further ensuring driving safety.

[0083] Meanwhile, because the roof box is installed at a high position, the brake signal emitted by the brake light group 51 located at the rear of the box body 3 can enter the field of vision of vehicles further behind earlier, thereby providing a certain braking warning to vehicles further behind, which can reduce the occurrence of chain rear-end collisions to a certain extent.

[0084] In one specific embodiment, three sets of brake lights 51 may be provided at the rear of the roof luggage compartment, and the three sets of brake lights 51 are arranged along the width direction of the trunk body 3 at the rear of the trunk body 3. When the vehicle decelerates slowly, that is, when the vehicle speed detected by the speed detector 52 decreases slowly, one of the brake lights 51 on the left or right side will light up; when the vehicle brakes suddenly, that is, when the vehicle speed detected by the speed detector 52 decreases significantly, the speed detector 52 will control the three sets of brake lights 51 to light up simultaneously and flash rapidly.

[0085] Specifically, such as Figure 13 As shown, each brake light assembly 51 includes a lamp housing 512, a lamp cover, and a circuit board. The lamp housing 512 has a mounting groove 513, and the lamp housing 512 is embedded in the mounting groove 513. Multiple lamp source components 511 are arranged in an array in the mounting groove 513 to provide uniform and bright brake light when the lamp source components 511 are lit. The circuit board is located on the side of the lamp housing 512 opposite to the mounting groove 513. The lamp source and the vehicle speed detection component 52 are electrically connected to the circuit board so that the vehicle speed data detected by the vehicle speed detection component 52 can be transmitted to the circuit board. After being processed by the circuit board, the multiple lamp source components 511 are controlled to emit light accordingly, realizing the electrical connection between the lamp source components 511 and the vehicle speed detection component 52.

[0086] The vehicle speed detection component 52 is an acceleration sensor to ensure the stability and accuracy of vehicle speed detection.

[0087] It should be noted that the light source component 511 is an LED light, and the lamp cover is a light-transmitting panel. The surface of the lamp cover is formed with a grid pattern to increase the aesthetics of the lamp cover and, to a certain extent, prevent the light from the light source component 511 from being too dazzling, thus affecting the driving safety of following vehicles.

[0088] Furthermore, a controller is installed inside the housing 3, and the vehicle speed detection element 52 and each group of brake lights 51 are electrically and / or signal-connected to the controller. Thus, when the vehicle speed detection element 52 detects a decrease in vehicle speed, it can transmit the corresponding detection signal to the controller, which can then control one group of brake lights 51 to illuminate or at least two groups of brake lights 51 to illuminate and flash. Preferably, the controller is a programmable LED controller.

[0089] The controller is connected to a pressure sensor, which is used to detect the braking force of the brake pedal. The degree of brake pedal depression detected by the pressure sensor is used in conjunction with the vehicle speed detection device 52 to further control the lighting status of the brake light assembly 51.

[0090] For example, when the pressure sensor detects that the braking force of the brake pedal is small, the vehicle speed decreases only slightly, and the controller controls one set of brake lights 51 to illuminate. When the pressure sensor detects that the braking force of the brake pedal is large, the vehicle speed decreases significantly, and the controller controls at least two sets of brake lights 51 to illuminate and flash, thus providing different braking warnings to following vehicles.

[0091] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
