[0002] This application claims priority to Chinese Patent Application No. 202422126533.6, filed on August 30, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This invention relates to the technical field of roof box locking mechanisms, and specifically to a roof box locking mechanism. Background Technology

[0004] Rooftop boxes are a common type of roof accessory. Their locking and closing mechanisms are typically located on the side of the box. During emergency braking or acceleration, items inside the rooftop box can rapidly shift due to inertia. These items may impact the end of the box, and since the end of the box usually lacks a locking mechanism, it's prone to opening upon impact, posing a significant safety hazard. Furthermore, the wind resistance generated during high-speed driving, as it travels along the windshield and over the roof, is blocked by the rooftop box. This creates significant lift at the end of the box, easily forcing it to open and severely compromising driving safety.

[0005] Therefore, we propose a locking mechanism installed at the end of the roof luggage compartment. Summary of the Invention

[0006] The present invention provides a roof luggage compartment locking mechanism to solve the problems mentioned in the background art.

[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0008] This invention discloses a roof box locking mechanism. The locking mechanism is disposed at the front end of the roof box and is used to resist the lift force generated by airflow acting on the front end of the box when the vehicle is traveling at high speed. The locking mechanism includes an upper locking hook and a lower locking mechanism installed at the ends of the upper and lower covers of the roof box and cooperating with each other. The lower locking mechanism includes an unlocking linkage mechanism, which is linked with an unlocking operation component installed on the side of the roof box.

[0009] Furthermore, the locking mechanism also includes a front cover, a rear cover, and an unlocking pause component. The unlocking pause component and the unlocking linkage mechanism are installed between the front cover and the rear cover. Specifically, the unlocking linkage mechanism includes a locking component and an unlocking component. The unlocking component is hinged to the locking component, and the locking component is rotatably mounted between the front cover and the rear cover via a first pin. The unlocking pause component is laterally positioned on the side of the locking component. The end of the unlocking component is linked to an unlocking operation device installed on the side of the roof trunk via an unlocking pull rope. The unlocking pull rope is a conventional hand-operated brake cable. The unlocking operation device is a linkage lock, and the end of the steel wire in the unlocking pull rope is connected to the linkage lock. The unlocking lever is fixedly connected. The operator uses the unlocking mechanism located on the side of the roof box to pull the unlocking component with the unlocking rope, causing the locking component to disengage from the upper locking hook. At this time, the locking mechanism is in a semi-unlocked state. At the same time, the unlocking pause component limits the locking component to prevent it from resetting. The operator does not need to continuously maintain the unlocking operation. When the roof box lid is opened, the upper locking hook disengages from the lower locking mechanism, causing the unlocking pause component to reset. After the locking component is no longer restricted by the unlocking pause component, it resets under the push of the unlocking component, so that it can automatically lock after the upper locking hook and the lower locking mechanism re-cooperate. At this time, the locking mechanism is in a fully unlocked state.

[0010] Furthermore, in order to enable the upper locking hook to cooperate with the lower locking mechanism to lock the upper and lower covers of the roof box, the upper locking hook specifically includes a locking hook body, and a locking groove is provided in the middle of the locking hook body to cooperate with the locking component. At the same time, a release hook with sloping upper and lower surfaces is provided at the bottom of the locking hook body and near the unlocking pause component, so that the upper locking hook can trigger the unlocking pause component when it is disengaged from the lower locking mechanism, thereby resetting the unlocking pause component and releasing the reset restriction on the locking component.

[0011] Furthermore, the front cover includes a front main cover body, in which a lock hole adapted to the size of the upper lock hook is integrally formed in the middle of the front main cover body along the direction of the upper lock hook insertion, and in the middle of the front main cover body, a first mounting groove and a second mounting groove for installing the locking component and the unlocking pause component are integrally formed, wherein the second mounting groove is located in the middle of the first mounting groove.

[0012] Furthermore, the inner side of the front main cover is integrally formed with a sliding groove for installing the unlocking component, and a slot is provided at the end of the sliding groove to fix the outer tube of the unlocking pull rope.

[0013] Furthermore, in order to effectively assemble the unlocking pause component, locking component, and unlocking component in conjunction with the aforementioned front cover, the rear cover specifically includes a rear main cover body. A positioning post for fixing the first pin is provided at the position corresponding to the first assembly groove on the rear main cover body. Simultaneously, a limiting component and a locking post are integrally formed at the positions corresponding to the sliding groove and the slot on the rear main cover body, respectively. The limiting component slides against the surface of the unlocking component after the rear cover and front cover are fastened together, without affecting the free sliding of the unlocking component in the sliding groove. The locking post is locked at the opening of the slot to prevent the end cap of the outer sleeve of the unlocking pull rope from disengaging from the slot. It should be noted that the engagement of the locking post and the slot does not compress the sleeve of the unlocking pull rope; therefore, this design does not affect the movement of the steel wire inside the unlocking pull rope under the action of the unlocking operation component.

[0014] Furthermore, in order to enable the unlocking pause component to simultaneously limit the locking component when it is unlocked by the locking hook, thus maintaining its unlocked state, the unlocking pause component specifically includes a connecting part and guide posts integrally formed at both ends of the connecting part. The two guide posts and the connecting part form a U-shaped structure, with the locking component located between the two guide posts. Simultaneously, the tail end of the guide posts is provided with a positioning hole for installing a first spring. One end of the first spring is fixed in the positioning hole, while the other end abuts against the bottom of the second mounting groove. It should be further noted that the second mounting groove is horizontally designed on the front main cover, and the unlocking pause component is slidably mounted within it. Additionally, a reset lock post and a reset / unlock keycap are integrally formed on the side of the connecting part near the locking component. Under normal conditions, the reset lock post slides against the side of the locking component. When the locking component rotates around the first pin under the pull of the unlocking component, it disengages from the lock groove in the upper locking hook. During this process, the locking component moves away from the front end of the reset pin, while the reset pin moves forward with the connecting part under the action of the first spring, blocking the reset path of the locking component, so that the entire locking mechanism is in a semi-unlocked state. The bottom of the reset unlock keycap is designed with an inclined angle, and the reset unlock keycap extends into the lock hole and corresponds to the release hook at the bottom of the upper locking hook. When the upper locking hook moves upward and disengages from the lower locking mechanism, the upper inclined surface of the release hook at the bottom of the locking hook body abuts against the lower inclined surface of the reset unlock keycap, thereby pushing the connecting part and the positioning pin to move backward and reset together with the reset unlock keycap. At this time, after the locking component loses the obstruction of the reset pin, it automatically resets under the action of the unlocking component, so that the locking mechanism changes from a semi-unlocked state to a fully unlocked state.

[0015] Furthermore, in order to enable the unlocking component to automatically lock the upper locking hook, the locking component specifically includes a sleeve cap fitted on the first pin, and a connecting arm integrally formed on the outside of the sleeve cap. One side of the front end of the connecting arm extends forward to form a lock head that cooperates with the lock groove. The bottom of the lock groove is inclined towards the locking component. When the upper locking hook cooperates with the locking component, the end face of the lock head in the locking component fits against the bottom of the lock groove. The front end of the connecting arm is integrally formed with a U-shaped connector facing downward. The connector has a strip-shaped mounting hole. The design of the strip-shaped mounting hole is mainly to prevent the unlocking component from being obstructed when the locking component is pulled to rotate.

[0016] Furthermore, to prevent the locking component from rotating excessively, a limiting ear is integrally formed on the outside of the sleeve cap. The limiting ear cooperates with the groove edge of the first assembly groove to limit the rotation angle of the connecting arm.

[0017] Furthermore, in order to enable the locking component to release and lock the upper hook, the unlocking component specifically includes an unlocking slider that is slidably assembled in the slide groove. The front end of the unlocking slider has an integrally formed connecting ear with a hole. The unlocking slider is hinged to the second pin and the strip-shaped assembly hole and the connecting head through the connecting ear. At the same time, the front of the unlocking slider has a pull rope positioning groove along the direction of the slide groove, and the end of the pull rope positioning groove near the slot has a slot for the unlocking pull rope to pass through. In order to realize the automatic reset of the locking component, and to ensure that the locking component will not be easily unlocked without the action of external force after it is engaged with the upper hook, a spring seat is integrally formed on the back of the unlocking slider near the lock hole. A second spring is installed between the spring seat and the end of the slide groove.

[0018] Furthermore, a metal pin is fixed to the front end of the steel wire in the unlocking rope, and the metal pin at the front end of the unlocking rope is locked in the rope positioning groove, and the end of the outer tube of the unlocking rope is locked in the groove.

[0019] The advantages of this invention over the prior art are as follows:

[0020] This invention is installed at the end of the roof box. Through the cooperation of the upper and lower locking mechanisms installed at the ends of the upper and lower covers, the fastening structure at the end of the roof box can be effectively locked. During vehicle operation, when the upper locking hook and locking component are not actively unlocked, the lift generated by wind resistance or the lifting force generated by impact will only make the cooperation between the upper locking hook and locking component tighter. This makes the locking effect between the upper and lower covers truly achieve the effect of the stronger the lift, the tighter the lock. It can effectively prevent the end of the luggage box from being forced to open under the action of impact or lift generated by wind resistance, and can effectively improve the locking strength and safety between the upper and lower covers.

[0021] The locking mechanism in this invention is linked to the unlocking operation component on the side of the roof box via an unlocking pull rope, so that the locking mechanism and the unlocking operation component form a certain angle. In addition to ensuring that the operability of the roof box is not affected when it is opened, compared with the traditional design where the unlocking and locking mechanisms are on the same straight line, it can increase the damping during the unlocking operation, thereby improving the safety of the roof box after it is closed and locked.

[0042] Currently, roof boxes typically lack locking mechanisms at their ends, making them prone to opening upon impact. Furthermore, during high-speed driving, wind resistance along the windshield and over the roof obstructs this airflow, creating significant lift at the box's end. This lift can easily force the previously closed box to open, severely compromising vehicle safety. Therefore, we propose a locking mechanism installed at the end of the roof box. This mechanism utilizes an upper locking hook 1 installed at the ends of the upper cover 3 and lower cover 4, which engages with a lower locking mechanism 2. In conjunction with this mechanism, the fastening structure at the end of the roof trunk can be effectively locked. During vehicle operation, when the locking hook 1 is not actively unlocked, the lift generated by wind resistance or the upward force generated by impact will only make the engagement between the locking hook 1 and the locking component 204 tighter. This ensures that the stronger the lift, the tighter the lock, effectively preventing the trunk end from being forced open due to impact or lift generated by wind resistance. This effectively improves the locking strength and safety between the upper cover 3 and the lower cover 4. The specific solution is as follows:

[0043] As shown in Figures 1, 10, and 11, this invention discloses a roof box locking mechanism. The locking mechanism is located at the front end of the roof box and is used to resist the lift force generated by airflow acting on the front end of the box when the vehicle is traveling at high speed.

[0044] The locking mechanism includes an upper locking hook 1 and a lower locking mechanism 2, which are installed at the ends of the upper cover 3 and the lower cover 4 of the roof luggage compartment and cooperate with each other.

[0045] The locking mechanism 2 includes an unlocking linkage mechanism, which is linked to an unlocking operation piece installed on the side of the roof trunk.

[0046] As shown in Figures 2 and 3, the locking mechanism 2 also includes a front cover 201, a rear cover 202, and an unlocking pause component 203. The unlocking pause component 203 and the unlocking linkage mechanism are installed between the front cover 201 and the rear cover 202. Specifically, the unlocking linkage mechanism includes two parts: a locking component 204 and an unlocking component 205. The unlocking component 205 is hinged to the locking component 204. The locking component 204 is rotatably installed between the front cover 201 and the rear cover 202 via a first pin 245. The unlocking pause component 203 is laterally arranged on the side of the locking component 204. The end of the unlocking component 205 is linked to the unlocking operation component installed on the side of the roof box via an unlocking pull rope 5. This locking mechanism is linked to the unlocking operation component on the side of the roof box via the unlocking pull rope 5, so that the locking mechanism and the unlocking operation component form a certain angle. In addition to ensuring that the operability of the roof box is not affected when it is opened, compared with the traditional design where the unlocking and locking mechanisms are on the same straight line, it can increase the damping feeling during the unlocking operation, thereby improving the security of the roof box after it is closed and locked.

[0047] The unlocking cable 5 is a conventional hand-operated brake cable; the unlocking mechanism is a linkage lock. The end of the steel wire in the unlocking cable 5 is fixedly connected to the unlocking lever in the linkage lock. The operator pulls the unlocking component 205 with the unlocking cable 5 through the unlocking mechanism located on the side of the roof box, causing the locking component 204 to disengage from the upper locking hook 1. At this time, the locking mechanism is in a semi-unlocked state, as shown in Figure 9. At the same time, the unlocking pause component 203 limits the locking component 204 to prevent it from resetting. The operator does not need to continuously maintain the unlocking operation on the unlocking mechanism. When the roof box cover 3 is opened, the upper locking hook 1 disengages from the lower locking mechanism 2, causing the unlocking pause component 203 to reset. After the locking component 204 is no longer restricted by the unlocking pause component 203, it resets under the push of the unlocking component 205, so that the upper locking hook 1 and the lower locking mechanism 2 can re-cooperate and automatically lock it. At this time, the locking mechanism is in a fully unlocked state, as shown in Figure 8.

[0048] As shown in Figures 2 and 7, in order to enable the upper locking hook 1 to cooperate with the lower locking mechanism 2 to lock the upper and lower covers 4 of the roof box, the upper locking hook 1 specifically includes a hook body 101, and a locking groove 102 that cooperates with the locking component 204 is provided in the middle of the hook body 101. At the same time, a release hook 103 with inclined surfaces on both the top and bottom is provided at the bottom of the hook body 101 and near the unlocking pause component 203, so that the upper locking hook 1 can trigger the unlocking pause component 203 when it is disengaged from the lower locking mechanism 2, so that the unlocking pause component 203 resets and releases the reset restriction on the locking component 204.

[0049] As shown in Figure 6, the front cover 201 includes a front main cover body 211. A lock hole 213 adapted to the size of the upper lock hook 1 is integrally formed in the middle of the front main cover body 211 along the direction of the lower insertion of the upper lock hook 1. A first mounting groove 214 and a second mounting groove 215 for installing the locking component 204 and the unlocking pause component 203 are integrally formed in the middle of the front main cover body 211, wherein the second mounting groove 215 is located in the middle of the first mounting groove 214.

[0050] The inner side of the front main cover 211 is also integrally formed with a slide groove 212 for installing the unlocking component 205, and a slot 216 is provided at the end of the slide groove 212 for fixing the outer tube of the unlocking pull rope 5.

[0051] To facilitate the effective assembly of the unlocking pause component 203, locking component 204, and unlocking component 205 with the aforementioned front cover 201, the rear cover 202 specifically includes a rear main cover body 221. A positioning post 224 for fixing the first pin 245 is provided on the rear main cover body 221 at the position corresponding to the first assembly groove 214. Simultaneously, a limiting component 222 and a locking post 223 are integrally formed on the rear main cover body 221 at the positions corresponding to the sliding groove 212 and the slot 216, respectively. The limiting component 222 is located at the rear... After the cover 202 and the front cover 201 are fastened together, they slide against the surface of the unlocking component 205 without affecting the free sliding of the unlocking component 205 in the slide groove 212. The locking post 223 is locked at the opening of the slot 216 to prevent the end of the outer tube of the unlocking pull rope 5 from disengaging from the slot 216. It should be noted that the cooperation between the locking post 223 and the slot 216 does not squeeze the sleeve of the unlocking pull rope 5. Therefore, this design does not affect the movement of the steel wire inside the unlocking pull rope 5 under the action of the unlocking operation component.

[0052] As shown in Figure 4, in order to enable the unlocking pause component 203 to limit the locking component 204 while the locking component 204 unlocks the locking hook 1, thus keeping it in the unlocked state, the unlocking pause component 203 specifically includes a connecting part 231 and guide posts 232 integrally formed at both ends of the connecting part 231. The two guide posts 232 and the connecting part 231 form a U-shaped structure, and the locking component 204 is located between the two guide posts 232. At the same time, the tail end of the guide post 232 is also provided with a positioning hole for installing the first spring 235. One end of the first spring 235 is fixed in the positioning hole, while the other end of the first spring 235 abuts against the bottom of the second mounting groove 215. It should be further noted that the second mounting groove 215 is horizontally designed on the front main cover 211, and its unlocking pause component 203 is slidably mounted within the second mounting groove 215. Meanwhile, a reset lock post 233 and a reset / unlock keycap 234 are integrally formed on the side of the connecting part 231 near the locking component 204. Under normal conditions, the reset lock post 233 slides against the side of the locking component 204. When the locking component 204 is pulled by the unlocking component 205, it rotates around the first pin 245, disengaging from the locking groove 102 in the upper locking hook 1. During this process, the locking component 204 moves away from the front end of the reset pin 233, while the reset pin 233 moves forward along with the connecting part 231 under the action of the first spring 235, blocking the reset path of the locking component 204, so that the entire locking mechanism is in a semi-unlocked state. The bottom of the reset / unlock keycap 234 is designed with an inclined angle, and the reset / unlock keycap 234 extends into the lock hole 213. And it corresponds to the release hook 103 at the bottom of the upper locking hook 1. When the upper locking hook 1 moves upward and disengages from the lower locking mechanism 2, the upper inclined surface of the release hook 103 at the bottom of the locking hook body 101 abuts against the lower inclined surface of the reset unlock key cap 234. Thus, the reset unlock key cap 234 pushes the connecting part 231 and the positioning post 224 to move backward and reset together. At this time, the locking component 204 loses the obstruction of the reset lock post 233 and is automatically reset under the action of the unlocking component 205, so that the locking mechanism changes from the semi-unlocked state to the fully unlocked state.

[0053] As shown in Figure 5, in order to automatically lock the upper hook 1 in conjunction with the unlocking component 205, the locking component 204 specifically includes a sleeve cap 241 fitted on the first pin 245, and a connecting arm 242 integrally formed on the outside of the sleeve cap 241. One side of the front end of the connecting arm 242 extends forward to form a lock head 247 that cooperates with the lock groove 102. The bottom of the lock groove 102 is inclined towards the locking component 204. When the upper hook 1 cooperates with the locking component 204, the end face of the lock head 247 in the locking component 204 fits against the bottom of the lock groove 102. The front end of the connecting arm 242 is integrally formed with a U-shaped connector 243 facing downward. The connector 243 has a strip-shaped mounting hole. The design of the strip-shaped mounting hole is mainly to prevent the unlocking component 205 from being obstructed when pulling the locking component 204 to rotate.

[0054] To prevent the locking component 204 from rotating excessively, a limiting ear 244 is integrally formed on the outside of the sleeve cap 241. The limiting ear 244 cooperates with the groove edge of the first assembly groove 214 to limit the rotation angle of the connecting arm 242.

[0055] As shown in Figure 5, in order to cooperate with the locking component 204 to release and lock the upper locking hook 1, the unlocking component 205 specifically includes an unlocking slider 251 that is slidably assembled in the slide groove 212. The front end of the unlocking slider 251 has an integrally formed connecting ear 252 with a hole. The unlocking slider 251 is hinged with the second pin 246 and the strip-shaped assembly hole and the connector 243 through the connecting ear 252. At the same time, the front of the unlocking slider 251 has a pull rope positioning groove 255 along the direction of the slide groove 212. The end of the pull rope positioning groove 255 near the slot 216 has a slot for the unlocking pull rope 5 to pass through. In order to realize the automatic reset of the locking component 204, and to ensure that the locking component 204 will not be easily unlocked without the action of external force after it is engaged with the upper locking hook 1, a spring seat 253 is integrally formed on the back of the unlocking slider 251 near the lock hole 213. A second spring 254 is installed between the spring seat 253 and the end of the slide groove 212.

[0056] The front end of the steel wire in the unlocking pull rope 5 is fixed with a metal pin. The metal pin at the front end of the unlocking pull rope 5 is locked in the pull rope positioning groove 255, and the end of the outer tube of the unlocking pull rope 5 is locked in the slot 216.

[0057] 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.
