[0040] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0041] Unless otherwise specified, the front-to-back direction in the present application is the longitudinal direction of the vehicle, that is, the X direction; the left-right direction is the lateral direction of the vehicle, that is, the Y direction; and the up-down direction is the vertical direction of the vehicle, that is, the Z direction.

[0042] An external storage box is installed outside the vehicle to provide users with a certain amount of storage space. It is commonly installed on the side or rear of the vehicle, with the rear being the most common. With the development of unmanned driving, many changes have been brought to cars, and active safety technology has become increasingly important.

[0043] In the field of vehicle safety, in order to improve rear-end collision safety, relevant technologies choose to arrange airbags in the rear bumper and other positions. On the one hand, the arrangement of airbags will impose relatively large restrictions on the bumper shape. On the other hand, the rear bumper is generally located low, and it is difficult to provide effective protection when being rear-ended by vehicles, especially trucks and other vehicles with higher bodies.

[0044] Based on the above considerations, the present application provides a rear-mounted storage device, a vehicle, and a vehicle control method, which improve the safety of the vehicle when it is rear-ended, and are convenient to arrange, have higher versatility, and have low maintenance costs, thereby improving economy and practicality.

[0045] Reference below Figure 1-Figure 7 A rear-mounted storage device according to an embodiment of the present application is described.

[0046] See also Figure 1 and Figure 2 The rear-mounted storage device 10 of the embodiment of the present application includes a box body 11 and a box cover 12. The box body 11 is used to be installed on the tailgate at the rear side of the vehicle, and the box cover 12 is arranged on a side of the box body 11 away from the tailgate.

[0047] The material, size and shape of the box 11 are not specifically limited, and can be made of high-strength composite materials. The size and shape can be designed according to the tailgate contour of common vehicle models to ensure stable installation and maximize space utilization. The surface of the box 11 is provided with a fixed interface that matches the tailgate of the vehicle, and a fast and reliable connection is achieved through a high-strength lock or quick release mechanism.

[0048] In one example, a plurality of bolts may be pre-embedded in the box body 11. During installation, the pre-embedded bolts pass through openings on the rear tailgate of the vehicle and are fastened with nuts on the sheet metal inside the tailgate.

[0049] The box cover 12 includes an inner cover 121 , an outer cover 122 and an airbag 123 .

[0050] The inner cover 121 is disposed outside the box body 11 and is sealed with the box body 11 to form a sealed storage space.

[0051] It is understandable that the box body 11 is provided with an opening on the side away from the tailgate to facilitate storage and access of items, the inner cover 121 is closely attached to the box body 11, and the inner cover 121 or the edge of the box body 11 can be equipped with a waterproof sealing ring to ensure the sealing of the storage space and prevent rain and dust from intruding. Exemplarily, the inner cover 121 and the box body 11 can be connected by a hinge to facilitate users to open and access items.

[0052] The outer cover 122 is disposed on a side of the inner cover 121 away from the box body 11 , and at least a portion of the outer cover 122 is spaced apart from the inner cover 121 along the X direction to form a cavity.

[0053] The inner cover 121 and the outer cover 122 can be fixedly connected by a plurality of screws distributed along the circumference, and the outer cover 122 covers the inner cover 121 and maintains a certain interval with the inner cover 121, and this interval constitutes a cavity for accommodating the airbag 123. Specifically, the outer cover 122 and the inner cover 121 are at least partially spaced along the X direction, so that the airbag 123 can be arranged directly behind the vehicle, and can play a more effective protective role when the airbag 123 is deployed.

[0054] The airbag 123 is installed in the cavity. When the airbag 123 is opened, it can open backwards and break through the outer cover 122 to the outside of the cavity.

[0055] The airbag 123 is arranged between the inner cover 121 and the outer cover 122. Through the layout design, it is ensured that it can be evenly and powerfully deployed along the rear of the vehicle when started, so as to effectively absorb the impact energy of a rear-end collision.

[0056] In some embodiments, a collision sensor may be provided on the rear storage device 10 to effectively detect rear collision information and ensure that the airbag 123 reacts quickly. Exemplarily, the integrated sensor network may be distributed throughout the key parts of the box 11 and the cover, and connected to the central control unit (CCU) of the vehicle, so as to monitor the rear collision event in real time. Once a rear-end collision is detected, the CCU immediately sends a command to activate the gas generator to quickly fill the airbag 123.

[0057] The specific form of the gas generator of the airbag 123 is not limited. For example, the gas generator can use advanced cold air gas generation technology to generate sufficient harmless gas in milliseconds to drive the airbag 123 to fill quickly and reduce damage to the vehicle occupants and the vehicle body. Considering the durability and maintenance convenience of long-term use, the airbag 123 and the gas generator are designed as modular units, which are easy to check and replace.

[0058] The material of the outer cover 122 can be selected to have a certain toughness and penetration, so that it can be appropriately broken when the airbag 123 is inflated, releasing the airbag 1231 to the outside of the vehicle.

[0059] In actual implementation, there are several advantages: 1. The rear-mounted storage device 10 not only plays a storage role, but also plays a buffering role after the vehicle is hit; 2. The rear-mounted storage device 10 protrudes from the vehicle body and basically becomes the first force point of the collision, and the height position is flexible, the internal space is larger, and the flexibility of the arrangement of the airbag 1231 is better. The height position of the cavity can be flexibly adjusted according to different vehicle models, which further improves the flexibility of the arrangement of the airbag 1231 and the protection efficiency, especially for the collision of vehicles with higher heights, the protection effect is more obvious; 3. The cover of the rear-mounted storage box adopts The double-layer structure can ensure its own rigidity, sealing, appearance and other requirements. The airbag 123 can just use the space between the inner cover 121 and the outer cover 122 without taking up too much storage space; 4. The rear-mounted storage is relatively independent of other parts of the car. Compared with the airbag 123, if it is arranged in the rear bumper or the tailgate, it has less impact on other related environmental parts; 5. The rear-mounted storage device 10 is more convenient to maintain. After a collision, the user does not need to leave the car in a 4S shop for repair. It only needs to be repaired or replaced separately, which avoids the trouble of using the car for the user, has lower maintenance costs, and is more economical and practical.

[0060] According to the rear-mounted storage device 10 provided in the embodiment of the present application, by integrating the airbag 123 in the rear-mounted storage device 10, it can not only play a storage role, but also improve the safety of the vehicle when it is rear-ended. It is convenient to arrange, has higher versatility, and has low maintenance costs, thereby improving economy and practicality.

[0061] See also Figure 2 , Figure 3 and Figure 4 According to some embodiments of the present application, the airbag 123 may be fixedly mounted on the inner cover 121 , and the outer side surface of the inner cover 121 may be provided with a groove 1211 , and at least a portion of the airbag 123 may be accommodated in the groove 1211 .

[0062] The groove 1211 on the outer side of the inner cover 121, i.e., the side of the inner cover 121 facing the outer cover 122, can be designed according to the shape and size of the airbag 123, so that the airbag 123 can be more stably installed in the groove 1211. The airbag 123 can be firmly fixed in the groove 1211 by means of high-toughness adhesive or mechanical buckle, screw connection, etc. This design not only ensures the stable storage of the airbag 1231 in the non-activated state, but also simplifies the assembly process and improves the overall manufacturing efficiency and reliability.

[0063] The groove 1211 may be partially recessed forward of the inner cover 121 to form the groove 1211 on the outer side of the inner cover 121; or partially protruded backward of the inner cover 121 to form the groove 1211 between at least two protruding structures. Both of these methods can minimize the occupation of the storage space when the airbag 123 is installed. For example, the distance between the airbag 123 and the outer cover 122 may be less than or equal to 20 mm.

[0064] Exemplarily, the groove 1211 may be flared from the bottom to the opening, so that the groove 1211 structure ensures the stability of the airbag 1231 while also reserving enough space for the airbag 1231 to be deployed quickly and unhindered when activated, and the opening of the groove 1211 faces backward, which effectively restricts the opening direction of the airbag 123, ensuring that the airbag 123 is deployed backward. The material of the airbag 1231 and the edge of the groove 1211 can be smoothly transitioned to avoid unnecessary friction or resistance when the airbag 1231 is inflated, thereby ensuring that it can be deployed quickly and completely in an emergency to achieve the expected protection effect.

[0065] According to some embodiments of the present application, the sidewall of the groove 1211 may be provided with a reinforcement structure.

[0066] The reinforcement structure of the side wall of the groove 1211 can be realized by local thickening, embedding metal or composite material support strips, or setting L-shaped or T-shaped ribs, etc. These designs can not only increase the rigidity of the groove 1211, but also effectively disperse the huge pressure generated by the airbag 123 when it is inflated, avoid deformation of the inner cover 121, and ensure that the airbag 1231 is deployed stably and reliably.

[0067] For example, the material used for the reinforcement structure is preferably a high-strength and lightweight material, such as carbon fiber reinforced plastic (CFRP), aluminum alloy, etc., to ensure that while increasing the strength, it does not impose too much burden on the overall weight of the storage device. It is manufactured through advanced processes such as precision injection molding, casting or machining to ensure structural accuracy and assembly quality.

[0068] By strengthening the side wall of the groove 1211, the normal working path of the airbag 1231 can be ensured to be unaffected even under extreme collision conditions, thereby preventing the airbag 123 from failing due to structural damage. In addition, the strengthened design also extends the service life of the storage device, especially in frequent opening and closing or long-term outdoor environments, it can still maintain good structural stability.

[0069] See also Figure 5According to some embodiments of the present application, the area where the projection of the airbag 123 on the outer cover 122 is located is the breaking area 1221, and the outer cover 122 is provided with a weakening groove 1222 in the breaking area 1221. When the airbag 123 is opened, the outer cover 122 is torn along the weakening groove 1222.

[0070] When the airbag 123 is opened, it opens backwards to impact the outer cover 122. Therefore, the area where the projection of the airbag 123 on the outer cover 122 is located is defined as the breaking area 1221 of the outer cover 122. In order to enable the breaking area 1221 to be torn quickly and orderly along a predetermined trajectory when the airbag 123 is inflated, a weakened groove 1222 can be provided in the breaking area 1221.

[0071] The weakened groove 1222 can be formed on the inner surface of the outer cover 122 by laser cutting or chemical etching, and its direction, depth and width are precisely calculated to reduce the local strength of the area so that it can be cracked in the direction of the force when it is subjected to the inflation pressure of the airbag 123. For example, the weakened groove 1222 can be a straight line, a curve or a grid, and the specific shape is customized according to the material properties of the outer cover 122 and the required rupture mode.

[0072] By designing the weakened groove 1222, it is possible to ensure that the outer cover 122 is torn along a preset path when the airbag 123 is deployed, thereby avoiding secondary damage or potential threats to the surrounding environment caused by disorderly rupture. This directional control technology improves the efficiency and safety of the deployment of the airbag 1231, ensuring that it can provide buffer protection for the rear vehicle in a timely and effective manner.

[0073] See also Figure 5 According to some embodiments of the present application, at least two weakening grooves 1222 may be provided, and at least two weakening grooves 1222 are connected and extend in different directions.

[0074] By providing at least two interconnected weakening grooves 1222 and arranging the weakening grooves 1222 in different directions, not only the controllability of the rupture of the outer cover 122 is enhanced, but also it is ensured that the airbag 123 can break through the outer cover 122 in a more precise and efficient manner and quickly deploy to cope with various collision angles.

[0075] At least two weakened grooves 1222 may be cross-connected or end-connected, and each weakened groove 1222 may be optimized and designed according to stress analysis to ensure that it can be broken along a preset direction under the pressure generated by the expansion of the airbag 1231. The interconnection of at least two weakened grooves 1222 forms a more flexible and stable rupture network, which can ensure that the outer cover 122 is torn in the direction that is most conducive to the release of the airbag 1231 even in a non-frontal collision.

[0076] In addition, the design of multiple weakened grooves 1222 effectively disperses local stress concentration, avoids accidental rupture caused by excessive stress at a single point, and improves the smoothness and safety of the entire rupture process. The extension strategy in different directions ensures that no matter how the expansion force of the airbag 1231 is distributed, the smoothest release path can be found.

[0077] The specific number of the weakened grooves 1222 is not limited, and can be two, three, four, or more than four, and is designed according to specific needs.

[0078] The shape of the weakened groove 1222 can also match the appearance of the exterior, and play an aesthetic role when the airbag 123 is not deployed.

[0079] See also Figure 5 According to some embodiments of the present application, the shape of at least two weakened grooves 1222 connected together is an open shape with at least one side open.

[0080] Each weakened groove 1222 can be designed to be semicircular, elliptical or other non-linear contours at the connection. These curved or non-linear edges form a one-side or multi-side opening after being connected, like a natural guide channel, so that the expansion force of the airbag 1231 is concentrated and guided to the weakest opening to achieve a rapid breakthrough. Through deformation guidance, the orderly separation of the outer cover 122 material along the weakened groove 1222 is promoted, and the overall safety performance is improved.

[0081] Moreover, the open shape ensures the integrity of the outer cover 122, that is, each part of the breaking area 1221 is connected to the area of ​​the outer cover 122 except the breaking area 1221, and after the outer cover 122 is torn open along the weakened groove 1222, the material of the breaking area 1221 is still connected to the outer cover 122, thereby preventing the fragments of the breaking area 1221 from splashing and causing harm to personnel and the surrounding environment, thereby improving the overall safety.

[0082] Exemplarily, three weakened grooves 1222 may be provided, and the three weakened grooves 1222 are connected in sequence to form a shape with an opening facing downward. When the airbag 123 is opened, the three weakened grooves 1222 are torn. Since the lower end of the breaking area 1221 remains connected, the cover of the breaking area 1221 is folded downward and opened to allow the airbag 123 to rush out.

[0083] According to some embodiments of the present application, the thickness of the region of the outer cover 122 corresponding to the airbag 123 is thinner than other regions.

[0084] The optimization of the local structure is used to assist the rapid and smooth deployment of the airbag 123. This thinning process effectively reduces the force required for the airbag 1231 to break through the outer cover 122 without sacrificing the overall structural stability of the outer cover 122, thereby accelerating the emergency response time. In one example, a reinforced frame or internal skeleton structure can be used to ensure that the thinned area can still maintain sufficient strength to withstand wear and slight impact in daily use, while being able to quickly respond to the need for the airbag 1231 to expand at a critical moment.

[0085] In some embodiments, the outer cover 122 may adopt a layered or gradient material structure near the breaking area 1221, with the outer layer being a hard layer with a certain toughness and the inner layer being a relatively soft weakened layer. This design further promotes controllable rupture along the weakened groove 1222 while also maintaining the integrity and aesthetic appearance of the rest of the outer cover 122.

[0086] See also Figure 6 According to some embodiments of the present application, the airbag 123 may include an airbag 1231, a plurality of legs 1232, and a connector 1233. The plurality of legs 1232 are distributed along the circumference of the airbag 1231, and the airbag 1231 may be fixed to the inner cover 121 through the plurality of legs 1232; the connector 1233 may be connected to the airbag 1231, and the connector 1233 is used to be electrically connected to a controller of the vehicle.

[0087] The airbag 1231 body can be made of high-strength nylon or similar high-temperature resistant and tear-resistant materials, and is designed to be rapidly inflated in a very short time to form a protective barrier. Its shape and size are precisely calculated to cover and protect the rear area of ​​the rear hanging storage device 10 to the greatest extent.

[0088] Multiple legs 1232 constitute a support structure for the airbag 1231. The center of the support structure is a core load-bearing structure. Multiple legs 1232 are arranged to extend around the airbag 1231 and are evenly distributed around the airbag 1231 to ensure that the airbag 1231 is firmly installed on the inner cover 121. For example, the legs 1232 can be fixed on the inner cover 121 by bolts or buckles. This ensures the accuracy of the positioning of the airbag 1231 and does not hinder the instantaneous deployment of the airbag 1231.

[0089] Connector 1233 acts as a bridge between the airbag 1231 system and the vehicle electronic control unit (ECU), and adopts a waterproof and shockproof design to ensure stable signal transmission even in harsh environments. Once the vehicle sensor detects a collision event, the ECU immediately activates the signal sent by connector 1233, triggering the gas generator to work and instantly inflate the airbag 1231. In one example, connector 1233 can support intelligent diagnosis functions, which facilitates regular inspection of the working status of the airbag 1231 system and improves maintenance efficiency.

[0090] See also Figure 7 , an embodiment of the present application also provides a vehicle.

[0091] The vehicle comprises a rear-mounted storage device 10 and a controller as in any of the above technical solutions, wherein the rear-mounted storage device 10 is installed on the tailgate of the vehicle; and the controller is electrically connected to the airbag 123 for controlling the opening of the airbag 123 .

[0092] It should be noted that, because the vehicle of the embodiment of the present application includes a rear-mounted storage device 10 as any of the above-mentioned technical solutions, it has the technical features and beneficial effects of the rear-mounted storage device 10 as any of the above-mentioned technical solutions, which will not be repeated here.

[0093] The controller built into the vehicle is directly electrically connected to the airbag 123 in the rear storage device 10. The controller may have advanced algorithm processing capabilities and be able to monitor the vehicle status and surrounding environment changes in real time. Once a collision event that may threaten the safety of the rear of the vehicle occurs, the controller will immediately start the preset safety response program and accurately control the rapid and orderly deployment of the airbag 123, thereby buffering the impact force and reducing damage in the first place.

[0094] According to the vehicle of the embodiment of the present application, by providing a rear-mounted storage device 10 as in the first aspect, by integrating the airbag 123 in the rear-mounted storage device 10, it can not only play a storage role, but also improve the safety of the vehicle when it is rear-ended, and it is convenient to arrange, more versatile, and has low maintenance costs, thereby improving economy and practicality. The airbag 123 can also be actively opened by controlling the controller to achieve active safety.

[0095] See also Figure 8 , an embodiment of the present application also provides a vehicle control method as described above in the technical solution.

[0096] The control method includes: step 30 and step 40.

[0097] Step 30: Obtain the relative speed and distance between the vehicle and the following vehicle;

[0098] Step 40: When the relative speed is greater than the speed threshold and the distance is less than the distance threshold, control the airbag 123 to open.

[0099] In step 30, the relative speed and actual distance between the vehicle and the following vehicle (the following vehicle) can be continuously monitored and acquired by using a radar sensor, camera or other advanced sensing equipment mounted at the rear of the vehicle. These data are fed back to the vehicle's central processor or a dedicated safety management system in real time.

[0100] In step 40, the system's built-in algorithm dynamically calculates the possibility of collision based on the received speed and distance data. Reasonable speed thresholds and distance thresholds are set as criteria for judging emergency situations. When it is detected that the relative speed exceeds the preset speed threshold and the distance between the two vehicles is lower than the distance threshold, the system immediately determines that there is a high risk of collision and triggers the early warning mechanism. Exemplarily, the speed threshold can be 30 km / h, 40 km / h, 50 km / h, 60 km / h or other speed values ​​between 30 km / h and 60 km / h, without specific limitation; the distance threshold can be 0.5 m, 1 m, 1.5 m, 2 m or other distance values ​​between 0.5 m and 2 m, without specific limitation.

[0101] Based on the above risk assessment results, the controller sends a command to the airbag 123 in the rear storage device 10, automatically starting the inflation process without the need for driver intervention, ensuring that the airbag 123 is ready before an actual collision occurs, thereby minimizing the potential impact of the collision.
