detailed description

The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, but not to limit the present disclosure.

In the present disclosure, unless otherwise stated, directional words such as "front" and "rear" are used relative to the traveling direction of the vehicle. For example, the front position is front and the rear position is rear. "Inner" and "outer" refer to the inside and outside of the contour of the corresponding structural component. The terms "first" and "second" are used without denoting any order or importance, but are used to distinguish one element from another. Additionally, where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated.

In the related art, the built-in collision sensors are mostly acceleration sensors. In order to avoid false triggering, the built-in collision sensors can usually only detect collisions with large acceleration changes, that is, collisions in high-speed driving scenarios, and collisions in low-speed driving scenarios. Then the effective collision signal cannot be collected. External collision detection switches are mostly installed outside the front of the car and are distributed in strips, so they can only cover collisions that occur in a designated small area. In addition, the external collision detection switch has poor adaptability to the vehicle shape, which affects the appearance, and the collision detection switch is mostly made of rubber material. Long-term exposure to the outside of the vehicle body will lead to accelerated aging and short service life.

As shown in FIG. 1 to FIG. 5 , the present disclosure provides a vehicle, which may be an unmanned vehicle, for example, an unmanned goods delivery vehicle for delivering goods in a logistics system, or an unmanned vehicle for delivering takeaway food. Takeaway delivery vehicles, or unmanned transfer vehicles used to transfer goods between multiple shelves. The vehicle includes a body shell 1 and a controller 2 . The body shell 1 includes a first casing 11 and a second casing 12 which are spaced apart along the inner and outer directions. The "spaced arrangement" means that there is a gap between the first casing 11 and the second casing 12 in a non-collision state. The "inner and outer direction" is relative to the vehicle body, the inner side of the body shell 1 refers to the side used for installation and contact with the vehicle body, and the outer side of the body shell 1 refers to the side away from the vehicle body and in contact with the obstacle S in a collision state side. In the embodiment shown in FIGS. 2 and 4 , the first casing 11 is used for mounting to the vehicle body, and the second casing 12 is in contact with the obstacle S in the collision state. That is, the second casing 12 is located outside the first casing 11 .

The first casing 11 and the second casing 12 are configured such that when the vehicle collides, the first casing 11 and the second casing 12 can be deformed and abutted so as to communicate with the controller 2 through the electrical connection therebetween. Send a collision signal. For example, the first housing 11 and the second housing 12 may be electrically connected to the controller 2 through wires 3, respectively. When the vehicle is in a non-collision state, the first housing 11 and the second housing 12 are arranged at intervals, and the first housing 11 , the second housing 12 and the controller 2 are in a disconnected state where there is no conduction. Once the body shell 1 is deformed by the collision, the first casing 11 and the second casing 12 abut against each other due to the deformation, so that a closed circuit is formed between the first casing 11 , the second casing 12 and the controller 2 . In the process of changing from an open circuit to a closed circuit, the current, voltage and resistance value in the circuit will change. Taking the change of the current as an example, the current sensed by the controller 2 is zero or negligible when the circuit is disconnected. When the circuit is closed, the generated current is enough to excite the controller 2. The controller 2 uses the current as a collision signal to send a signal to the vehicle. The braking system issues commands to control the vehicle to stop, avoid secondary injuries caused by not stopping in time, and ensure the personal safety of people inside and outside the vehicle. The controller 2 may be integrated in a vehicle ECU (Electronic Control Unit, electronic control unit), or an independent controller for controlling the braking system may also be provided, which is not limited in this disclosure.

Compared with the acceleration sensor used in the unmanned vehicle in the related art, which can only detect large acceleration changes, the vehicle of the present disclosure, whether it is driving at a high speed or a low speed, as long as the severity of the collision is sufficient to make the first housing 11 and the first shell 11 and the third The two shells 12 are deformed and abutted against each other, so that the controller 2 can detect the collision signal, and the versatility is stronger. Compared with the expensive acceleration sensor, the present disclosure integrates the body shell 1 as the collision detection device, which has a simple structure and lower cost. In addition, compared with the collision detection switch installed outside the vehicle body, since the body shell 1 has strong plasticity, the adaptability to the shape of the vehicle is also stronger. The shape is adaptable, and the problem of accelerated aging due to the exposed rubber of the collision detection switch can also be avoided.

In order to realize the above-mentioned function of the first casing 11 and the second casing 12 being in contact with each other due to deformation, so as to send a collision signal to the controller 2 through the electrical connection therebetween, the first casing 11 and the second casing 12 They can be made of metal materials, for example, the first shell 11 and the second shell 12 are respectively metal sheet metal parts. Alternatively, in order to reduce the weight of the entire vehicle, the first casing 11 and the second casing 12 may also be made of non-metallic materials under the condition of ensuring the strength of the entire vehicle.

When the first shell 11 and the second shell 12 are made of non-metallic materials, in order to ensure that the first shell 11 and the second shell 12 are in contact with each other due to deformation, the first shell 11 and the second shell 12 A closed loop can be formed between the controller 2 and the first housing 11 . The first housing 11 includes a first body 111 and a first conductor 112 disposed on the surface of the first body 111 facing the second housing 12. The second housing 12 includes a second body 121 and a second conductor 122 disposed on a surface of the second body 121 on the side facing the first housing 11, the first conductor 112 and the second conductor 122 are corresponding in position and are respectively The controller 2 is electrically connected.

The first body 111 and the second body 121 may be metal or non-metal. When the vehicle collides, the first body 111 and the second body 121 can be deformed, thereby making the first conductor 112 and the second conductor 122 abut against each other. In the embodiments shown in FIG. 2 and FIG. 4 , the first conductor 112 and the second conductor 122 may be respectively formed as conductive adhesive layers. One end of the wire 3 is embedded in the conductive adhesive layer, and the other end is connected to the controller 2 . According to some other embodiments of the present disclosure, the first electrical conductor 112 and the second electrical conductor 122 may also be metal contacts. The metal contacts can be in contact with the deformation of the first body 111 and the second body 121 , one end of the wire 3 can be welded to the metal contacts, and the other end is connected to the controller 2 .

In order to further expand the range of collision detection, according to an embodiment of the present disclosure, the first electrical conductors 112 and the second electrical conductors 122 may be uniformly distributed in the entire area of the body shell 1 . For example, when the first conductor 112 and the second conductor 122 are conductive adhesive layers, the conductive adhesive layers may be attached to cover the entire surfaces of the first body 111 and the second body 121 . When the first conductor 112 and the second conductor 122 are metal contacts, a plurality of metal contacts may be evenly spaced and distributed on the entire surfaces of the first body 111 and the second body 121 . By distributing the first electrical conductors 112 and the second electrical conductors 122 in the entire area of the body shell 1 as described above, no matter which part of the vehicle body has a collision, it can be effectively detected, and the vehicle can be braked in time to reduce collision damage .

The body shell 1 also includes an insulating support 13 provided between the first casing 11 and the second casing 12 . The insulating support members 13 are connected to the first case 11 and the second case 12, respectively, thereby connecting the first case 11 and the second case 12 as an integral body shell 1 . The insulating supporter 13 is provided in plural to improve the connection strength between the first case 11 and the second case 12 . The supporting member 13 is made of insulating material, which can ensure that the first casing 11 and the second casing 12 will not be in a conducting state in a non-collision state, so as to avoid disturbing the normal operation of the vehicle.

Further, the insulating support member 13 may be an elastic member, for example, the insulating support member 13 may be made of elastic rubber. In the embodiment shown in FIGS. 2 and 4 , the elastic rubber and the first casing 11 and the second casing 12 are respectively bonded together by, for example, an adhesive. The elastic rubber can provide sufficient support strength for the first shell 11 and the second shell 12, and the elastic rubber also has good elastic deformation ability, and can be compressed with the deformation of the body shell 1 when the vehicle collides. The density of the plurality of insulating support members 13 can be determined according to the actual situation, and it is preferable not to interfere with the normal abutment of the first casing 11 and the second casing 12 after a collision occurs. In addition, the elastic rubber can absorb part of the collision energy due to its good elastic deformation ability, and reduce the collision damage to the vehicle. According to other embodiments of the present disclosure, the insulating support 13 may also adopt an insulating spring, which can also absorb part of the collision energy while supporting and connecting the first housing 11 and the second housing 12 .

The hardness of the buffer layer 14 is greater than that of the first case 11 and the second case 12 . In this way, when the second casing 12 is deformed and moves toward the first casing 11 after being hit by the obstacle S, the buffer layer 14 can provide support for the first casing 11 to prevent the second casing 12 from moving toward the first casing 11 . When a casing 11 moves, the first casing 11 is also deformed under the action of the elastic rubber, thereby affecting the contact between the first casing 11 and the second casing 12 . Further, the buffer layer 14 can be made of foamed material. In this way, the buffer layer 14 can buffer the collision force while providing support for the first casing 11 , so as to protect the personal safety of persons inside and outside the vehicle.

As shown in FIG. 5 , the body shell 1 of the present disclosure may be one or more of a front shell 101 , a rear shell 102 , a roof shell 103 , or a side shell 104 .
