Detailed Description

In the following, only certain exemplary embodiments are briefly described. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present disclosure. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.

Autonomous vehicles are intelligent vehicles that are driven using high performance computing hardware instead of a driver. The computing hardware, as the "brain" of the autonomous vehicle, needs to analyze and process a large amount of data transmitted by a camera or a radar or other devices in real time.

In the related art, when the automatic driving vehicle collides with other vehicles or objects, computing hardware is likely to be damaged due to impact, so that data in the computing hardware is lost, and reference basis cannot be provided for later accident analysis.

Based on this, the embodiment of the disclosure provides a computing hardware protection device and an autonomous vehicle, so as to provide protection for computing hardware of the autonomous vehicle when the autonomous vehicle collides, and prevent data loss of the computing hardware.

As shown in fig. 1, 2, 3 and 4, a computing hardware protection device 100 provided by the embodiment of the disclosure includes a bracket 10 and at least one airbag device 14, wherein the bracket 10 includes at least one mounting portion 11 for being fixedly connected with a vehicle body 200 (shown in fig. 4) of an autonomous vehicle, a first fixing portion 12 for being fixedly connected with computing hardware 300 of the autonomous vehicle, and at least one second fixing portion 13 adjacent to the first fixing portion 12, the at least one airbag device 14 is fixed to the at least one second fixing portion 13 in a one-to-one correspondence manner, and the at least one airbag device 14 is used for deploying an airbag 140 thereof when receiving a trigger signal. As shown in fig. 2, in the disclosed embodiment, the airbag 140 is deployed by: the inside of the airbag 140 is filled with a large amount of gas, so that the volume is rapidly expanded.

The computing hardware protection device 100 provided by the embodiment of the disclosure is applied to an autonomous vehicle, and when the autonomous vehicle collides with another vehicle or an object and the collision meets a certain condition (for example, when a specified collision strength is reached), the airbag 140 of the at least one airbag device 14 is rapidly deployed, so that the computing hardware 300 and a wire harness 310, a connector (not shown in the figure) and the like connected around the computing hardware 300 can be effectively protected, and the damage of the computing hardware 300 due to the vehicle collision is reduced or even avoided, so that the data loss in the computing hardware 300 is effectively prevented, and a reference basis is provided for later-period accident analysis.

Vehicles are often equipped with airbag systems. An airbag system is a passive safety protection system that is typically used in conjunction with a seat belt to provide effective crash protection for the occupant. The safety air bag system mainly comprises a collision sensor, an air bag device, an electronic control device and the like. When the vehicle collides with another vehicle or an object, the collision sensor detects the collision strength and sends a detection signal to the electronic control device, and the electronic control device triggers the airbag device to rapidly deploy the airbag through the drive circuit when determining that the collision strength satisfies the airbag deployment condition (for example, when a prescribed collision strength is reached). The air bag device mainly comprises an air bag, a gas generator, an igniter and the like, and the working principle is as follows: the igniter ignites the gas generator after receiving the trigger signal sent by the electronic control device, and the gas generator rapidly generates a large amount of nitrogen in the air bag so as to unfold the air bag and rapidly expand the air bag. When a passenger contacts with the deployed airbag, the airbag can absorb energy generated during a collision in a buffering manner, so that the passenger is prevented from being injured or the injury degree is reduced.

In some embodiments of the present disclosure, the aforementioned at least one airbag device 14 is configured to be connected to an electronic control device of an airbag system of an autonomous vehicle for deploying the airbag 140 upon receiving a triggering signal from the electronic control device. That is, when the automatically driven vehicle collides and the collision satisfies a certain condition, not only the airbag 140 of the airbag device 14 provided for the computing hardware 300 but also the airbag of the airbag device provided for the passenger in the vehicle is deployed to protect the computing hardware 300 from being damaged as much as possible. In this embodiment, the control logic for triggering the computing hardware protection device 100 to start protection is simple, and can be started synchronously with the airbag system, so that the safety and reliability are realized.

In the disclosed embodiment, the specific structural form of the stent 10 is not limited. As shown in fig. 3, in some embodiments, the bracket 10 is a sheet metal part and is substantially "zigzag", and has the characteristics of light weight, high strength, easy manufacturing and convenient installation, and can be manufactured and molded by a stamping process.

In the disclosed embodiments, a component or components are generally "shaped," and it is understood that the overall shape is similar to the "shape," and is not required to be absolutely identical in shape.

In this embodiment, the bracket 10 includes a first plate portion 101, a second plate portion 102, a third plate portion 103, a fourth plate portion 104, and a fifth plate portion 105 connected in a bent manner in this order, wherein at least one mounting portion 11 includes two mounting portions 11, the two mounting portions 11 are located in the first plate portion 101 and the fifth plate portion 105 in a one-to-one correspondence, and the first fixing portion 12 and the at least one second fixing portion 13 are located in the third plate portion 103. The connection in a bending manner in sequence can be understood as that two adjacent plate parts are bent relatively through a stamping process so as to form a certain included angle.

In the present embodiment, the mounting portion 11 refers to a portion of the bracket 10 for fixedly connecting with the vehicle body 200, the first fixing portion 12 refers to a portion of the bracket 10 for mounting the computing hardware 300, and the second fixing portion 13 refers to a portion of the bracket 10 for mounting the airbag device 14. The specific configuration of the mounting portion 11, the first fixing portion 12, and the second fixing portion 13 is not limited.

In some embodiments, the at least one second fixing portion 13 includes a plurality of second fixing portions 13 arranged around the first fixing portion 12. Thus, a plurality of airbag devices 14 can be arranged around the computing hardware 300, and the computing hardware 300 can be protected from a plurality of directions, so that the impact on the computing hardware can be weakened or even avoided.

As shown in fig. 1, the computing hardware 300 is generally shaped as a flat rectangular parallelepiped, and a plurality of input/output interfaces are provided around the periphery thereof. Various sensors, radars, cameras, positioning devices, electronic control devices, etc. of the autonomous vehicle may be communicatively coupled to the plurality of input/output interfaces of the computing hardware 300 via cables. In addition, expansion slots and the like may be provided around the computing hardware 300 for configuring expansion cards as required. To keep the cabling neat, the various cables around the computing hardware 300 are typically bundled and routed together (e.g., bundled harness 310 in fig. 1).

As shown in fig. 1 and 3, in some embodiments, the at least one second fixing portion 13 may include four second fixing portions 13 surrounding the first fixing portion 12 and arranged substantially in a rectangular shape, and the at least one airbag device 14 includes four airbag devices 14 fixed to the four second fixing portions 13 in a one-to-one correspondence. When the computing hardware 300 is laid flat on the autonomous vehicle, for example, fixed in a space below a bulkhead of a trunk (which is a part of a vehicle body), the four airbag apparatuses 14 protect the computing hardware 300 in all directions, respectively, from the front, rear, left, and right, so that the impact of a vehicle collision on the computing hardware 300 can be minimized.

In some embodiments of the present disclosure, some airbag devices may also be selectively disposed in some areas around the computing hardware 300 based on the particular installation environment of the computing hardware 300. For example, the airbag devices 14 are disposed only on the rear, left, and right three sides of the computing hardware 300, respectively.

As shown in fig. 1 and 3, in some embodiments, each of the second fixing portions 13 is a strip fixing groove, and each of the airbag devices 14 is fitted into the corresponding strip fixing groove. The airbag 140 of the airbag device 14 has a substantially strip shape after deployment.

This embodiment is designed to prevent the airbag device 14 in the non-activated state from scratching other external structures, thereby reducing the possibility of damage to the airbag device 14, and is also beneficial to reducing the occupied space of the computing hardware protection device 100, so that the installation position thereof can be flexibly designed according to the needs.

As shown in fig. 1, in some embodiments of the present disclosure, each airbag device 14 has a gap between both end side walls of the corresponding strip fixing groove. With this embodiment design, on the one hand, an expansion space is provided for the deployment of the airbag 140; on the other hand, the adjacent airbags 140 can be prevented from interfering with each other after deployment; on the other hand, as shown in fig. 1 and 2, the uniformly arranged wire harnesses 310 may be routed through the gap, and after the adjacent airbags 140 are deployed, a part of the wire harnesses is located between the adjacent airbags 140 so as to be protected by the airbags 140, so that the sensors, the radar, the camera, the positioning device, and the like may be supported to the maximum extent to send real-time data of the vehicle collision moment to the memory of the computing hardware 300 for storage, thereby providing a reference for later-period accident analysis.

As shown in fig. 3, in the embodiment of the present disclosure, the bottom wall of the bar-shaped fixing groove is provided with at least one first fixing hole 131 for fixing the airbag device 14. The airbag device 14 may be fixedly coupled to the bracket 10 by a fastener (e.g., a screw, a bolt, or a rivet) provided at the at least one first fixing hole 131.

As shown in fig. 3, in some embodiments, each mounting portion 11 is provided with at least one second fixing hole 111 for fixedly connecting with a vehicle body 200 (e.g., a trunk portion of the vehicle body). The bracket 10 may be fixedly coupled to the vehicle body 200 by a fastener (e.g., a screw, a bolt, or a rivet) provided at the at least one second fixing hole 111. In some embodiments, the first fixing portion 12 is provided with at least one third fixing hole 121 for fixedly connecting with the computing hardware 300. The computing hardware 300 may be fixedly connected to the bracket 10 by a fastener (e.g., a screw, a bolt, or a rivet) provided at the at least one third fixing hole 121.

The embodiment of the present disclosure further provides an autonomous driving vehicle, which includes the computing hardware protection device 100 of the foregoing embodiment, and the computing hardware 300 fixed on the first fixing portion 12 of the bracket 10 of the computing hardware protection device 100.

The specific location of the computing hardware protection device 100 on the vehicle is not limited, and may be located in the engine compartment of the vehicle, the bottom of the vehicle, the top of the vehicle, or the trunk, for example. As shown in fig. 4, in some embodiments of the present disclosure, the computing hardware protection device 100 is secured within a trunk, for example, in a space below a partition within the trunk, thereby enabling a hidden installation.

When the automatically driven vehicle collides with other vehicles or objects and the collision meets a certain condition, the airbag device 14 of the computing hardware protection device 100 is rapidly activated, so that the computing hardware 300 and the wiring harness 310, the plug connectors and the like connected around the computing hardware 300 can be effectively protected, and the damage of the computing hardware 300 caused by the vehicle collision is reduced or even avoided, thereby effectively preventing the data loss in the computing hardware 300 and providing a reference basis for the later-stage accident analysis.
