背景技术Background technique

防撞缓冲结构通常安装在车辆的前保险杠和防撞主梁之间，用于在车辆与行人等发生碰撞时进行缓冲吸能，以降低发生碰撞时对行人造成的伤害。The anti-collision buffer structure is usually installed between the front bumper and the main anti-collision beam of the vehicle.

具体实施方式Detailed ways

为了能够更清楚地理解本公开的上述目的、特征和优点，下面将对本公开的方案进行进一步描述。需要说明的是，在不冲突的情况下，本公开的实施例及实施例中的特征可以相互组合。In order to understand the above objects, features and advantages of the present disclosure more clearly, the solutions of the present disclosure will be further described below. It should be noted that, as long as there is no conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

在下面的描述中阐述了很多具体细节以便于充分理解本公开，但本公开还可以采用其他不同于在此描述的方式来实施；显然，说明书中的实施例只是本公开的一部分实施例，而不是全部的实施例。Many specific details are set forth in the following description to fully understand the present disclosure, but the present disclosure can also be implemented in other ways different from those described here; obviously, the embodiments in the description are only part of the embodiments of the present disclosure, and Not all examples.

参照图1至图3所示，本实施例提供一种防撞缓冲结构，包括防撞主梁2、前保险杠3以及可膨胀的气囊1；Referring to Figures 1 to 3, this embodiment provides an anti-collision buffer structure, including an anti-collision main beam 2, a front bumper 3 and an inflatable airbag 1;

其中，防撞主梁2和前保险杠3沿车辆的行进方向依次设置；Among them, the anti-collision main beam 2 and the front bumper 3 are arranged sequentially along the traveling direction of the vehicle;

气囊1设于防撞主梁2的靠近前保险杠3的一侧，且气囊1可在受触发时自防撞主梁2与前保险杠3之间的缝隙弹出至前保险杠3外。The airbag 1 is located on the side of the anti-collision main beam 2 close to the front bumper 3, and the airbag 1 can pop out of the gap between the anti-collision main beam 2 and the front bumper 3 when triggered.

具体实现时，防撞主梁2和前保险杠3可以为沿着车尾至车头的方向依次设置。在正常状态下，气囊1连接在防撞主梁2上且位于防撞主梁2的靠近前保险杠3的一侧。当车辆与行人发生碰撞时，气囊1则受到触发后从防撞主梁2和前保险杠3之间的缝隙弹出至前保险杠3外，即弹出至车头外部以便于与人体接触，从而对人体进行缓冲吸能作用，以降低对人体造成的碰撞伤害。During specific implementation, the anti-collision main beam 2 and the front bumper 3 may be arranged sequentially along the direction from the rear to the front of the vehicle. Under normal conditions, the airbag 1 is connected to the anti-collision main beam 2 and is located on the side of the anti-collision main beam 2 close to the front bumper 3 . When the vehicle collides with a pedestrian, the airbag 1 is triggered and pops out from the gap between the main beam 2 and the front bumper 3 to the outside of the front bumper 3, that is, to the outside of the front of the vehicle to facilitate contact with the human body, thus causing damage to the vehicle. The human body performs a buffering and energy-absorbing function to reduce collision damage to the human body.

即就是说，相比于现有技术中的注塑材质吸能块或者金属材质吸能块或者发泡材质吸能块而言，本实施例的气囊1的不仅硬度较小、材质更为柔软，且还具有较好的缓冲吸能作用，可以有效降低对行人的伤害值。That is to say, compared with the injection-molded energy-absorbing blocks, metal energy-absorbing blocks, or foaming material energy-absorbing blocks in the prior art, the airbag 1 of this embodiment not only has a smaller hardness and a softer material, but also has a softer material. It also has a good buffering and energy-absorbing effect, which can effectively reduce the damage to pedestrians.

具体实现时，防撞主梁2的靠近前保险杠3的一侧设置有背离前保险杠3凹陷的容置 槽，气囊1压缩在容置槽内。During specific implementation, the side of the anti-collision main beam 2 close to the front bumper 3 is provided with a recessed accommodation facing away from the front bumper 3. slot, and the airbag 1 is compressed in the accommodation slot.

也就是说，防撞主梁2的靠近前保险杠3的一侧背离车头的方向凹陷形成用于容纳气囊1的容置槽。在车辆与行人未发生碰撞前，气囊1压缩并容置在容置槽内，使得其在车辆内的占用空间较小，从而相比于现有技术中的吸能块的厚度较大导致车辆的前悬长度较大的方式而言，本实施例的防撞缓冲结构通过设置压缩的气囊1，则可以有效降低车辆的前悬长度。当车辆与行人发生碰撞时，气囊1迅速被触发后弹出前保险杠3外并处于充气状态，以对行人起到缓冲保护作用。That is to say, the side of the anti-collision main beam 2 close to the front bumper 3 is recessed away from the front of the vehicle to form an accommodating groove for accommodating the airbag 1 . Before a collision occurs between the vehicle and a pedestrian, the airbag 1 is compressed and accommodated in the receiving groove, so that it occupies a smaller space in the vehicle. Therefore, compared with the prior art, the thickness of the energy-absorbing block is relatively large, causing the vehicle to In terms of a vehicle with a larger front overhang length, the anti-collision buffer structure of this embodiment can effectively reduce the vehicle's front overhang length by providing a compressed airbag 1 . When a vehicle collides with a pedestrian, the airbag 1 is quickly triggered and pops out of the front bumper 3 and remains in an inflated state to provide buffering protection for the pedestrian.

本实施例中，容置槽的开口具体可以设置为朝向前保险杠3的一侧，使得车辆与行人发生碰撞时，气囊1可以朝向前保险杠3的方向从容置槽中弹出并自防撞主梁2与前保险杠3之间的缝隙弹出至前保险杠3外，以与行人接触从而对行人进行缓冲保护。也就是说，容置槽可以对气囊1的弹出操作进行导向，以避免气囊1发生弹出故障的问题。In this embodiment, the opening of the accommodating groove can be set toward one side of the front bumper 3, so that when the vehicle collides with a pedestrian, the airbag 1 can be ejected from the accommodating groove toward the direction of the front bumper 3 and prevent the collision. The gap between the main beam 2 and the front bumper 3 pops up to the outside of the front bumper 3 to contact pedestrians to cushion and protect them. That is to say, the accommodating groove can guide the ejection operation of the airbag 1 to avoid the problem of ejection failure of the airbag 1 .

为了使得行人与车辆发生碰撞时，气囊1可以对行人更好地进行保护，气囊1可以设置为多个，多个气囊1沿着车辆的宽度方向间隔设置，从而提升气囊1对行人的缓冲保护效果。具体的气囊1的设置数目可以根据实际需要设定。In order to better protect pedestrians when a pedestrian collides with a vehicle, the airbag 1 can be provided with multiple airbags 1 , and the plurality of airbags 1 are spaced apart along the width direction of the vehicle, thereby improving the buffering protection of the pedestrian by the airbag 1 Effect. The specific number of airbags 1 can be set according to actual needs.

当气囊1设置为多个时，防撞主梁2上用于容纳气囊1的容置槽也可以设置为多个，即一个气囊1容置在一个容置槽内，使得各气囊1在发生碰撞点爆时可以不受彼此的干涉。或者，也可以为多个气囊1存储在一个容置槽内，以降低制造成本。When multiple airbags 1 are provided, the number of accommodating slots for accommodating the airbags 1 on the anti-collision main beam 2 can also be set to be multiple, that is, one airbag 1 is accommodated in one accommodating slot, so that each airbag 1 is They can explode without interference from each other during collision. Alternatively, multiple airbags 1 can also be stored in one storage tank to reduce manufacturing costs.

具体实现时，防撞主梁2的靠近前保险杠3的一侧还具有蒙皮，气囊1设于蒙皮的靠近前保险杠3的一侧。蒙皮与气囊1的连接结构具体可以为：气囊1的靠近蒙皮的一侧设置有第一连接部，蒙皮上与第一连接部对应的位置设置有与第二连接部，气囊1通过第一连接部和第二连接部的配合与蒙皮连接。In specific implementation, the side of the anti-collision main beam 2 close to the front bumper 3 also has a skin, and the airbag 1 is provided on the side of the skin close to the front bumper 3 . The connection structure between the skin and the airbag 1 can be specifically as follows: a first connection part is provided on the side of the airbag 1 close to the skin, and a second connection part is provided on the skin at a position corresponding to the first connection part, and the airbag 1 passes through The first connecting part and the second connecting part are matched with the skin.

示例性的，第一连接部可以为卡接凸起，第二连接部为与卡接凸起卡接配合的卡槽；或者，第一连接部为螺纹连接柱，第二连接部为与螺纹连接柱啮合的螺纹孔。For example, the first connection part may be a snap-in protrusion, and the second connection part may be a slot that snap-fits with the snap-in protrusion; or the first connection part may be a threaded connection post, and the second connection part may be a threaded connection post. Threaded holes for coupling posts to engage.

在其他实现方式中，气囊1和蒙皮还可以通过热熔胶等进行粘接连接。In other implementation methods, the airbag 1 and the skin can also be bonded and connected through hot melt glue or the like.

进一步地，本实施例的防撞缓冲结构还包括点爆器52，点爆器52用于与气囊1连接从而用于触发气囊1弹出。具体实现时，当气囊1设置为多个时，多个气囊1可以通过一个点爆器52进行点爆，以降低成本。或者，点爆器52可以设置为多个，一个点爆器52控制点爆一个气囊1，使得不同的气囊1之间独立控制进行点爆，使得点爆效率更高。示例性的，点爆器52具体可以为***点爆器。具体的，***点爆器通常由汽油或***等气体发生剂配合点火装置组成充气模块，从而使得气囊1弹出前保险杠3外后处于充气状态以便于 对行人进行保护。Furthermore, the anti-collision buffer structure of this embodiment also includes an igniter 52 , which is used to connect with the airbag 1 to trigger the airbag 1 to eject. In specific implementation, when multiple airbags 1 are provided, the multiple airbags 1 can be detonated through one detonator 52 to reduce costs. Alternatively, multiple detonators 52 may be provided, and one detonator 52 controls the detonation of one airbag 1, so that different airbags 1 can be detonated independently, resulting in higher detonation efficiency. For example, the detonator 52 may be an explosive detonator. Specifically, the explosive detonator usually consists of a gas generating agent such as gasoline or explosives and an ignition device to form an inflatable module, so that the airbag 1 is in an inflated state after being popped out of the front bumper 3 so as to facilitate Protect pedestrians.

另外，本实施例中，为了进一步降低车辆与行人发生碰撞时行人的伤害程度，可以设置车辆与行人发生碰撞之前就预先将气囊1弹出以便对行人进行缓冲保护。具体的，在车辆与行人发生碰撞前就预先将气囊1弹出的控制结构为：在车辆上设置检测装置4以及与检测装置4通信连接的控制点爆装置5。检测装置4用于检测车辆的车速信息以及车辆前方的行人信息，并将车速信息和行人信息发送给控制点爆装置5，控制点爆装置5根据车速信息以及行人信息控制气囊1在车辆发生碰撞前点爆并自容置槽弹出至车辆的前保险杠3外，以对行人进行缓冲保护。In addition, in this embodiment, in order to further reduce the degree of injury to pedestrians when a vehicle collides with a pedestrian, the airbag 1 can be pre-populated before the vehicle collides with a pedestrian to cushion and protect the pedestrian. Specifically, the control structure for pre-populating the airbag 1 before the vehicle collides with a pedestrian is to provide a detection device 4 on the vehicle and a control ignition device 5 that is communicatively connected to the detection device 4 . The detection device 4 is used to detect the vehicle speed information and pedestrian information in front of the vehicle, and send the vehicle speed information and pedestrian information to the control ignition device 5. The control ignition device 5 controls the airbag 1 according to the vehicle speed information and pedestrian information when the vehicle collides. It is detonated at the front and pops out from the accommodating groove to the outside of the front bumper 3 of the vehicle to buffer and protect pedestrians.

也就是说，通过车速信息和行人信息计算车辆与行人发生碰撞的时间点或者距离，使得车辆在于行人未发生碰撞前就点爆气囊1，以使得气囊1自容置槽弹出至车辆的前保险杠3外，通过气囊1弹出到前保险杠3外与人体直接接触，气囊1的硬度较小，从而有效降低车辆与行人发生碰撞时的伤害程度。并且，在行人与车辆即将发生碰撞前就弹出气囊1以对行人进行缓冲保护，可以进一步降低行人与车辆碰撞时的伤害程度。That is to say, the vehicle speed information and pedestrian information are used to calculate the time point or distance of the collision between the vehicle and the pedestrian, so that the vehicle detonates the airbag 1 before the pedestrian collides, so that the airbag 1 pops out from the accommodation slot to the front insurance of the vehicle. Outside the bumper 3, the airbag 1 pops up to the outside of the front bumper 3 and directly contacts the human body. The hardness of the airbag 1 is smaller, thereby effectively reducing the degree of injury when the vehicle collides with a pedestrian. Moreover, the airbag 1 is deployed before a collision between a pedestrian and a vehicle to cushion and protect the pedestrian, which can further reduce the degree of injury caused by a collision between a pedestrian and a vehicle.

具体实现时，检测装置4包括车速传感器41和检测雷达42，车速传感器41和检测雷达42均与控制点爆装置5通信连接；车速传感器41用于检测车辆的车速信息并将车速信息发送至控制点爆装置5，检测雷达42用于检测车辆前方的行人信息并将行人信息发送至控制点爆装置5。During specific implementation, the detection device 4 includes a vehicle speed sensor 41 and a detection radar 42. Both the vehicle speed sensor 41 and the detection radar 42 are communicatively connected with the control ignition device 5; the vehicle speed sensor 41 is used to detect the vehicle speed information of the vehicle and send the vehicle speed information to the control unit. The detonation device 5 and the detection radar 42 are used to detect pedestrian information in front of the vehicle and send the pedestrian information to the control detonation device 5 .

具体的，车速传感器41可以为车辆自带的检测车辆当前车速的传感器。而检测雷达42可以为摄像头或者红外传感器，以检测车辆前方是否有行人，并且在检测到车辆前方有行人时，检测行人与车辆目前的距离。Specifically, the vehicle speed sensor 41 may be a vehicle's own sensor that detects the vehicle's current vehicle speed. The detection radar 42 can be a camera or an infrared sensor to detect whether there is a pedestrian in front of the vehicle, and when detecting a pedestrian in front of the vehicle, detect the current distance between the pedestrian and the vehicle.

具体实现时，控制点爆装置5包括彼此通信连接的控制器51和点爆器52；控制器51与检测装置4通信连接，以获取车速信息和行人信息，并根据车速信息和行人信息判断车辆是否会发生碰撞；点爆器52用于在控制器51判断车辆会发生碰撞前点爆气囊1。During specific implementation, the control ignition device 5 includes a controller 51 and an ignition device 52 that are communicatively connected to each other; the controller 51 is communicatively connected with the detection device 4 to obtain vehicle speed information and pedestrian information, and determine the vehicle based on the vehicle speed information and pedestrian information. Whether a collision will occur; the detonator 52 is used to detonate the airbag 1 before the controller 51 determines that the vehicle will collide.

也就是说，通过控制器51根据车速信息和行人信息来检测车辆是否会碰撞到行人，当判断车辆会碰撞到行人时，则迅速通过点爆器52点爆气囊1，使得气囊1自容置槽弹出至车辆的前保险杠3外，通过气囊1弹出到前保险杠3外与人体直接接触，气囊1的硬度较小，从而有效降低车辆与行人发生碰撞时的伤害程度。并且，在行人与车辆即将发生碰撞前就弹出气囊1以对行人进行缓冲保护，可以进一步降低行人与车辆碰撞时的伤害程度。That is to say, the controller 51 detects whether the vehicle will collide with a pedestrian based on the vehicle speed information and pedestrian information. When it is determined that the vehicle will collide with a pedestrian, the airbag 1 is quickly detonated through the igniter 52 so that the airbag 1 is self-contained. The slot pops up to the outside of the front bumper 3 of the vehicle, and the airbag 1 pops out to the outside of the front bumper 3 to directly contact the human body. The hardness of the airbag 1 is small, thereby effectively reducing the degree of injury when the vehicle collides with a pedestrian. Moreover, the airbag 1 is deployed before a collision between a pedestrian and a vehicle to cushion and protect the pedestrian, which can further reduce the degree of injury caused by a collision between a pedestrian and a vehicle.

具体的点爆器52的结构和点爆器52点爆气囊1的方式可以参照现有技术中的相关描述，本实施例对此不做详细描述。 For the specific structure of the igniter 52 and the manner in which the igniter 52 ignites the airbag 1 , reference can be made to the relevant descriptions in the prior art, which will not be described in detail in this embodiment.

针对控制车辆在即将发生碰撞前就可以弹出气囊1的一种方式可以为：控制器51包括处理模块511和计时模块512，处理模块511分别与检测装置4、计时模块512以及点爆器52通信连接；计时模块512用于在检测装置4检测到行人信息开始记录车辆接下来的行驶时长。处理模块511用于根据车速信息和行人信息计算车辆与行人之间的实时距离，并在实时距离小于预设安全距离时控制点爆器52点爆气囊1。One way to control the vehicle to eject the airbag 1 before a collision may be: the controller 51 includes a processing module 511 and a timing module 512. The processing module 511 communicates with the detection device 4, the timing module 512 and the detonator 52 respectively. Connection; the timing module 512 is used to record the next driving time of the vehicle after the detection device 4 detects pedestrian information. The processing module 511 is used to calculate the real-time distance between the vehicle and the pedestrian based on the vehicle speed information and pedestrian information, and control the detonator 52 to detonate the airbag 1 when the real-time distance is less than the preset safe distance.

示例性的，比如车辆行进方向的前方有行人出现的情况下：此时处理模块511根据车辆的当前车速和车辆当前距离行人的距离计算到车辆距离行人的实时距离已经小于预设安全距离时，即点爆气囊1。比如，车辆当前的车速为v1，车辆当前距离行人的距离为s1，车辆的行驶时长为t1，车辆距离行人的实时距离s2＝s1-v1×t1，当s2小于预设安全距离时，则立即控制点爆器52点爆气囊1。预设安全距离比如可以为10m，或者15m，具体根据实际需要设定，本实施例对此不做限定。For example, for example, when a pedestrian appears in front of the vehicle in the direction of travel: at this time, the processing module 511 calculates based on the current speed of the vehicle and the current distance between the vehicle and the pedestrian that the real-time distance between the vehicle and the pedestrian is less than the preset safe distance, That is, the air bag 1 is exploded. For example, the current speed of the vehicle is v1, the current distance between the vehicle and the pedestrian is s1, the driving time of the vehicle is t1, and the real-time distance between the vehicle and the pedestrian is s2 = s1-v1×t1. When s2 is less than the preset safe distance, the vehicle immediately Control the detonator 52 to detonate the air bag 1. The preset safety distance may be, for example, 10 m or 15 m, which is set according to actual needs. This embodiment does not limit this.

针对控制车辆在即将发生碰撞前就可以弹出气囊1的另一种方式可以为：控制器51包括处理模块511，处理模块511分别与检测装置4和点爆器52通信连接；处理模块511用于根据车速信息和行人信息计算车辆行驶至行人所在位置时所需的时长，并在所需时长等于预设安全时长时控制点爆器52点爆气囊1。Another way to control the vehicle to eject the airbag 1 before a collision may be: the controller 51 includes a processing module 511, which is communicatively connected to the detection device 4 and the detonator 52 respectively; the processing module 511 is used to Calculate the time required for the vehicle to drive to the pedestrian's location based on the vehicle speed information and pedestrian information, and control the igniter 52 to explode the airbag 1 when the required time is equal to the preset safe time.

示例性的，比如车辆行进方向的前方有行人出现的情况下：此时处理模块511根据车辆的当前车速和车辆当前距离行人的当前距离确定车辆行驶至行人所在位置处的时长，从而可以在该时长等于预设安全时长时控制点爆器52点爆气囊1。For example, for example, when a pedestrian appears in front of the vehicle in the direction of travel: At this time, the processing module 511 determines the length of time for the vehicle to drive to the pedestrian's location based on the current speed of the vehicle and the current distance between the vehicle and the pedestrian, so that it can be When the duration is equal to the preset safety duration, the detonator 52 is controlled to detonate the airbag 1.

举例来说，比如车辆当前的车速为v1，车辆当前距离行人的距离为s1，则车辆行驶至行人所在位置处所需要的时长t3＝s1/v1。当t3等于或小于预设安全时长时则立即控制点爆器52点爆气囊1。比如，计算得到车辆行驶至行人所在位置处所需要的时长为5s，而预设安全时长为3s，则车辆在继续行驶2s后则需立即点爆气囊1。For example, if the current speed of the vehicle is v1 and the current distance between the vehicle and the pedestrian is s1, then the time required for the vehicle to travel to the pedestrian's location is t3 = s1/v1. When t3 is equal to or less than the preset safety time, the igniter 52 is immediately controlled to ignite the airbag 1. For example, if the calculated time required for the vehicle to drive to the pedestrian's location is 5 seconds, and the preset safety time is 3 seconds, the vehicle needs to activate the air bag 1 immediately after continuing to drive for 2 seconds.

具体的预设安全时长根据实际需要设定，本实施例对此不做限定。The specific preset safety time period is set according to actual needs, and is not limited in this embodiment.
