Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive safety technology, and in particular relates to a device for deploying airbags before a collision. Background Technology
[0002] Currently, vehicle crash beams mostly rely on metal structures to absorb energy. When a vehicle collides head-on with a pedestrian or other object, the metal structure generates a strong impact force during the process of absorbing the collision energy, which is difficult to effectively buffer and can easily cause serious injury or death to the people or animals that are hit, leaving the safety of objects outside the vehicle unprotected.
[0003] Existing airbag systems primarily focus on protecting occupants in the driver's cabin, completely neglecting the protection needs of objects outside the vehicle during collisions. Once a collision occurs, the object outside the vehicle directly bears the massive impact without any effective protective device to mitigate the injury, greatly increasing the severity of the accident. Furthermore, the collision sensors in the airbags are mostly installed in specific locations, and the airbag will only deploy when the impact force directly acts on the sensor and reaches a threshold. If the collision location is off-center or the force distribution is uneven, the sensor may not be able to accurately detect the signal, causing the airbag to fail to deploy in time, thus reducing the reliability of the airbag.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects, not to describe a particular order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.
[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0027] This utility model embodiment provides a device for deploying an airbag before a collision, such as... Figure 1-8 As shown, the device for deploying airbags before a collision includes: a crash beam 1; a plurality of radar components 2 evenly distributed at the front end of the crash beam 1, the plurality of radar components 2 being used to eliminate detection blind spots; an infrared thermal imaging module 3 installed at the front end of the crash beam 1 for identifying the object being collided with; a plurality of airbags 4 evenly distributed at the front end of the crash beam 1 and in the extended areas on both sides of the crash beam 1 for protecting the object being collided with outside the vehicle; insert rods 8 all slidably disposed on the crash beam 1 for installing the plurality of airbags 4; and mounting mechanisms all disposed on the crash beam 1 for assembling the plurality of airbags 4.
[0028] In this embodiment, an airbag 4 module is installed at the front end of the anti-collision beam 1, covering the front end surface of the anti-collision beam 1 and the extended areas on both sides. The collision risk is identified by the vehicle identification system (including radar component 2 and infrared thermal imaging module 3). When the collision risk is identified, a signal is sent to the control system to control the actuator to trigger the airbag 4.
[0029] When a vehicle collision occurs, the energy absorption coordination mechanism comes into play. The airbag 4 and the anti-collision beam 1 form a stepped energy absorption mode. At the moment of collision, the airbag 4 absorbs energy first. Through the buffering effect of the airbag 4, the impact force generated by the collision is effectively dispersed, reducing the injury to the collided object and the occupants of the vehicle. When the airbag 4 reaches its energy absorption limit, the anti-collision beam 1 begins to play its energy absorption role, further absorbing the remaining collision energy, providing dual protection for the vehicle and occupants. In addition, in low-speed and minor collisions, the airbag 4 does not need to be deployed, avoiding injury to the occupants caused by the deployment of the airbag 4 and avoiding the need for replacement of the airbag 4.
[0030] Since the airbag 4 is installed via the insert rod 8 and the mounting mechanism on the anti-collision beam 1, and the airbag 4 and the anti-collision beam 1 are independent units, it is convenient to replace the airbag 4 independently in the future. By evenly distributing several radar components 2 at the front end of the anti-collision beam 1, blind spots can be effectively eliminated, the surrounding environment can be perceived more comprehensively, and collision risks can be identified in advance. The infrared thermal imaging module 3 can identify the type of the object being collided with, and control the early triggering time of the airbag 4 according to different objects, making the triggering more precise and improving the protection effect. Through the stepped energy absorption design of the airbag 4 and the anti-collision beam 1, energy can be absorbed more effectively during a collision, reducing the damage to the vehicle and the object being collided with. Because the airbag 4 and the anti-collision beam 1 adopt an independent unit design, the airbag 4 can be replaced independently. After a low-speed collision, only the airbag 4 needs to be replaced, and the anti-collision beam 1 does not need to be replaced, which reduces maintenance costs.
[0031] In a further preferred embodiment of the present invention, the radar component 2 includes alternating millimeter-wave radar and ultrasonic radar, and the radar component 2 is distributed in an arc-shaped array at the front end of the anti-collision beam 1, together forming a 120° horizontal detection sector.
[0032] In this embodiment, these radar components 2 operate simultaneously during vehicle operation. The millimeter-wave radar uses electromagnetic waves in the millimeter-wave band to detect information such as the distance, speed, and angle of the target object; the ultrasonic radar measures the distance to the target object by emitting and receiving ultrasonic waves. The two are arranged alternately in an arc-shaped array, forming a 120° horizontal detection sector. This sector can comprehensively detect objects, collect surrounding environmental data in real time, and transmit the data to the vehicle's identification system. This arc-shaped array layout combines the advantages of millimeter-wave radar and ultrasonic radar, expanding the detection range and improving the accuracy and reliability of detection. It effectively eliminates blind spots and can detect potential collision risks more promptly and accurately.
[0033] In a further preferred embodiment of this utility model, the installation mechanism includes: an installation groove 5 formed on the front side of the anti-collision beam 1; an installation block 6 fixedly installed on the outer shell of the airbag 4, the installation block 6 being inserted into the installation groove 5; a connecting cavity 7 formed in the anti-collision beam 1, the insertion rod 8 being slidably disposed in the connecting cavity 7, and the insertion rod 8 slidably extending into the installation groove 5 and penetrating the installation block 6; a stop block 9 fixedly installed at one end of the insertion rod 8; a limiting mechanism provided on the anti-collision beam 1 and the connecting cavity 7 for limiting and fixing the insertion rod 8; and a moving mechanism provided on the connecting cavity 7 for moving the insertion rod 8 and loading and unloading the airbag 4.
[0034] In this embodiment, the mounting block 6 is aligned with the mounting groove 5 so that it can be inserted into the groove 5, initially determining the installation position of the airbag 4 on the crash beam 1. The insert rod 8 is then slidably extended into the mounting groove 5 via a moving mechanism, passing through the mounting block 6, completing the initial installation and fixation of the airbag 4. Afterwards, a limiting mechanism activates, limiting the stop block 9 and the insert rod 8 to prevent it from retracting into the connecting cavity 7, ensuring the airbag 4 is securely installed and can deploy normally during a collision. Through the precise alignment of the mounting block 6 and the mounting groove 5, and the insertion rod 8 passing through the mounting block 6 and the limiting mechanism's control over the insert rod 8 and stop block 9, the airbag 4 is firmly installed on the crash beam 1. During vehicle operation, even when encountering bumps or severe pre-collision shaking, the airbag 4 will not easily detach, ensuring normal deployment when needed and providing reliable collision protection.
[0035] In a further preferred embodiment of the present invention, the limiting mechanism includes: a groove 10 formed on one side of the anti-collision beam 1, and a connecting port 11 formed in the groove 10 and communicating with the connecting cavity 7; a sliding plate 12 slidably disposed in the groove 10; and a limiting block 13 fixedly installed on the inner side of the sliding plate 12 and extending into the connecting cavity 7 through the connecting port 11, wherein the limiting block 13 is located on the right side of the stop block 9 for limiting the stop block 9.
[0036] In this embodiment, after the insert rod 8 is inserted into the mounting block 6, the slide plate 12 is pushed into the slide groove 10. Then, the slide plate 12 is slid to move to the left along the slide groove 10. As the slide plate 12 moves, the limiting block 13 also moves. When one side of the slide plate 12 contacts the left side of the slide groove 10, the limiting block 13 simultaneously contacts the stop block 9 in the connecting cavity 7. At this time, the stop block 9 is blocked by the limiting block 13 and cannot retract to the right, thereby preventing the insert rod 8 from retracting into the connecting cavity 7 and ensuring that the airbag 4 is installed securely. Then, the fastening bolt 16 is used to fix the slide plate 12 in the current position of the slide groove 10, further ensuring that the limiting effect of the limiting block 13 on the stop block 9 is stable and reliable.
[0037] In a further preferred embodiment of the present invention, a limiting groove 14 is provided on the slide plate 12, and a limiting rod 15 is fixedly installed in the groove 10. The limiting rod 15 is slidably connected to the limiting groove 14 to limit the slide plate 12 within the groove 10. A fastening bolt 16 is threadedly installed on the slide plate 12, and the fastening bolt 16 is threadedly connected to the anti-collision beam 1 to fix the slide plate 12.
[0038] In this embodiment, during the sliding process of the slide plate 12, the limiting groove 14 gradually slides and connects with the limiting rod 15, thereby limiting the sliding trajectory of the slide plate 12, preventing the slide plate 12 from disengaging from the slide groove 10 during the sliding process, and ensuring that the slide plate 12 can slide smoothly along the predetermined direction. When the slide plate 12 slides to the appropriate position, the operator tightens the fastening bolt 16 so that the fastening bolt 16 is threadedly connected to the anti-collision beam 1, thereby fixing the slide plate 12 in the current position of the slide groove 10.
[0039] In a further preferred embodiment of this utility model, the moving mechanism includes: two connecting grooves 17 formed at the bottom of the anti-collision beam 1, and a through opening formed in the anti-collision beam 1 and communicating with the connecting cavity 7 and the connecting grooves 17; a first pull rope 18 fixedly installed on one side of the stop block 9 and extending into the connecting groove 17 through the through opening; a reset spring 19 sleeved on the first pull rope 18 for resetting the insertion rod 8, the two ends of the reset spring 19 being fixedly connected to the stop block 9 and one side of the connecting cavity 7 respectively; and a pull ring 20 fixedly installed on the first pull rope 18.
[0040] In this embodiment, when the airbag 4 needs to be replaced, the slide plate 12 is first removed to release the restriction on the stop block 9. Then, the operator pulls the pull ring 20, which pulls the stop block 9 through the first pull rope 18. After the stop block 9 is pulled, it drives the insertion rod 8 to slide into the connecting cavity 7, so that the insertion rod 8 gradually moves away from the mounting block 6 until the insertion rod 8 is completely pulled out of the mounting block 6. During this process, the return spring 19 is compressed and stores elastic potential energy. When the insertion rod 8 is completely pulled out, the mounting block 6 is no longer constrained by the insertion rod 8. At this time, the airbag 4 can be taken out of the mounting slot 5 for replacement.
[0041] In a further preferred embodiment of the present invention, a guide block 21 is fixedly installed in the connecting cavity 7, and the guide block 21 is slidably connected to the sliding opening of the insertion rod 8.
[0042] In this embodiment, the guide block 21 is slidably connected to the sliding opening of the insertion rod 8, providing precise guidance for the movement of the insertion rod 8. When installing the airbag 4, the insertion rod 8 can move accurately along the guide block 21 and be inserted into the installation block 6, avoiding the problem of the airbag 4 not being installed correctly due to the deviation of the insertion rod 8.
[0043] In a further preferred embodiment of this utility model, a fixing rod 22 is fixedly installed at the bottom of the insertion rod 8, an installation cavity 23 is provided in the anti-collision beam 1, a U-shaped frame 24 is slidably provided at the bottom of the connecting cavity 7, the bracket of the U-shaped frame 24 slides into the installation cavity 23, a second pull rope 25 is fixedly installed at the bottom of the U-shaped frame 24, the second pull rope 25 extends into the connecting groove 17 through the through-hole, and a pull ring 20 is also installed on the second pull rope 25. A connecting spring 26 is fixedly installed at the bottom of the U-shaped frame 24, and the bottom end of the connecting spring 26 is fixedly connected to the installation cavity 23.
[0044] In this embodiment, when the airbag 4 needs to be replaced, the slide plate 12 used for the limiting block 9 is first removed to release the limiting of the block 9. Then, the pull ring 20 on the first pull rope 18 is pulled. The first pull rope 18 pulls the block 9 and the insertion rod 8 to slide into the connecting cavity 7, so that the insertion rod 8 slides away from the mounting block 6. At the same time, the reset spring 19 is compressed and stores elastic potential energy.
[0045] During the sliding of the insertion rod 8, the fixing rod 22 moves synchronously with the insertion rod 8. The fixing rod 22 moves along the inclined surface of one side of the U-shaped frame 24, applying downward pressure to the U-shaped frame 24, causing the U-shaped frame 24 to slide downward at the bottom of the connecting cavity 7, and its bracket slides in the mounting cavity 23. At the same time, the connecting spring 26 is compressed and contracted. When the fixing rod 22 slides to the U-shape between the U-shapes of the U-shaped frame 24, the connecting spring 26 releases the stored elastic potential energy, pushing the U-shaped frame 24 upward and limiting the fixing rod 22 between the U-shapes of the U-shaped frame 24. At this time, the insertion rod 8 is fixed in the current position and cannot be reset by the elastic force stored in the reset spring 19, which provides convenient conditions for the subsequent replacement of the airbag 4.
[0046] In summary, compared with related technologies, this device identifies collision risks through radar components and infrared thermal imaging modules, triggers airbags, and forms a stepped energy absorption with the anti-collision beam to reduce damage. Furthermore, the airbags are installed independently, making them easy to replace and reducing maintenance costs.
