At present, the car can provide effective safety protection for passengers inside the car, but lacks protection for pedestrians outside the car. The braking system needs to be judged by humans or by testing agencies. However, when the vehicle is traveling at high speed, the intelligent detection function of the braking system is effective, but it cannot adjust the vehicle to a braking stop in time when a pedestrian suddenly appears, which will cause injury to the pedestrian.

[0035] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0036] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0037] With the continuous development of the automotive industry, people have increasingly higher requirements for vehicle safety while driving. Currently, while effective safety protection can be achieved for passengers inside the vehicle, the safety protection for pedestrians outside the vehicle can only be accomplished by the vehicle's braking system. However, the braking system needs to be activated by human judgment or intelligent detection by a testing agency before it can brake the vehicle. When the vehicle is traveling at high speed, there is a certain delay in human judgment and intelligent detection, and the activation of the braking system has a certain lag. After the braking system is activated, the vehicle will still slide a distance due to inertia and cannot stop immediately. When a pedestrian suddenly appears during the journey, although the vehicle can adjust to braking mode, it is still inevitable to cause harm to pedestrians or animals. The vehicle's safety protection effect against external living beings is poor.

[0038] refer to Figures 1-5 As shown, in order to reduce the collision force between the vehicle and the object to be detected outside the vehicle and improve the vehicle's safety protection effect against external organisms, this application provides a vehicle including a safety protection component 10, a detection mechanism 30, and a control component. The safety protection component 10 is disposed on the front bumper 20 of the vehicle and includes an airbag assembly 11 and an ejection assembly 12. The ejection assembly 12 is used to deploy the airbag assembly 11. The detection mechanism 30 is disposed at the front of the vehicle and includes a distance detection element and a speed detection element. The distance detection element is used to detect the distance between the vehicle and the object to be detected, and the speed detection element is used to detect the vehicle's driving speed. The control component is electrically connected to the detection mechanism 30 and is used to control the start and stop state of the ejection assembly 12.

[0039] A safety protection component 10 is installed at the position of the front bumper 20 of the vehicle. The safety protection component 10 includes an airbag component 11 and an ejection component 12. The ejection component 12 can be electrically connected to the control component. When the detection mechanism 30 detects a dangerous situation, the ejection component 12 will deploy the airbag component 11. By providing safety protection for the object to be detected by the airbag component 11 installed at the front of the vehicle, the serious damage to pedestrians or buildings caused by the vehicle in an emergency is reduced.

[0040] The airbag assembly 11 can effectively reduce the collision force between the front of the vehicle and the object to be detected outside the vehicle, thereby providing effective safety protection for the living organism in front of the vehicle. After receiving the ejection signal from the detection mechanism 30, the control assembly controls the ejection assembly 12 to release the airbag assembly 11, causing the airbag assembly 11 to eject towards the object to be detected, thereby improving the protection effect of the object to be detected.

[0041] In one embodiment, the ejection assembly 12 may be equipped with a steering assembly (not shown in the figure). The detection mechanism 30 can detect the distance between the vehicle and the object to be detected, the vehicle's speed, and the location of the object to be detected. When the vehicle speed exceeds a preset value and the distance between the vehicle and the object to be detected is less than a preset distance, the detected location of the object to be detected is transmitted to the control assembly. The control assembly controls the steering assembly to rotate the airbag assembly 11 so that the airbag assembly 11 faces the location of the object to be detected. At the same time, the airbag assembly 11 is deployed to protect the object to be detected, reduce the collision force between the vehicle and the object to be detected, and reduce the damage to the object to be detected.

[0042] The vehicle in this embodiment may also include other necessary components or structures such as tires, transmission mechanism, engine, and control system. The corresponding arrangement and connection relationships can be referenced from vehicles in the prior art. The connection relationships, operation, and working principles of any unmentioned structures are known to those skilled in the art and will not be described in detail here. It is understood that the vehicle in this application embodiment can be any vehicle with mobility capabilities, including vehicles with autonomous or intelligent driving capabilities, such as passenger vehicles (cars, public vehicles, buses, minibuses, etc.), cargo vehicles (ordinary trucks, box trucks, trailer trucks, enclosed trucks, tank trucks, flatbed trucks, container trucks, dump trucks, special structure trucks), special vehicles (logistics delivery vehicles, patrol vehicles, cranes, excavators, bulldozers, loaders, road rollers, off-road engineering vehicles, armored engineering vehicles, sewage treatment vehicles), recreational vehicles (entertainment vehicles, amusement park autonomous driving devices, balance scooters, etc.), and rescue vehicles (e.g., fire trucks, ambulances, power repair vehicles, engineering emergency vehicles, etc.).

[0043] Furthermore, the airbag assembly 11 includes an airbag 111 and an air supply component. The air supply component is used to inflate the airbag 111 and is electrically connected to the control assembly. After the airbag 111 is inflated by the air supply component and deployed by the ejection assembly 12, the air supply component simultaneously inflates the airbag 111, causing it to expand. This effectively buffers the impact between the vehicle and objects to be detected, such as people, animals, or buildings, further reducing the collision force between the vehicle and the objects and minimizing damage to the objects.

[0044] As an example, the air supply component can be set as an air cylinder. When the control component receives the start signal, it controls the air cylinder to inflate the airbag 111 and controls the amount of air supplied to the airbag 111 according to the vehicle speed and the interval distance, which can further improve the flexibility in the process of using the safety protection component 10.

[0045] In another embodiment, an air pump can be used to inflate the airbag 111. The airbag assembly 11 also includes an air extraction component that is connected to the airbag 111 and is used to extract gas from the airbag 111 to improve the flexibility of the airbag assembly 11 during use.

[0046] Furthermore, the gas supply component includes an igniter 1 and a reaction cylinder 2. The reaction cylinder 2 includes a receiving cavity 201 and a first opening 202 communicating with the receiving cavity 201. The igniter 1 is disposed within the receiving cavity 201, which contains reactants. The igniter 1 is used to ignite the reactants to generate gas. The airbag 111 includes a second opening 110, and the first opening 202 is connected to the second opening 110. Through the chemical reaction between the igniter 1 and the reactants, the inflation speed and efficiency of the airbag 111 are improved, allowing the airbag 111 to quickly open and protect the object under test. This reduces the delay in the installation and use of the protective components and improves the safety protection effect for pedestrians, organisms, and buildings.

[0047] In one embodiment, when the ejection assembly 12 ejects the airbag assembly 11 toward the object to be detected, the igniter 1 is simultaneously controlled to ignite the reactant. After the reactant undergoes a chemical reaction, a large amount of gas is rapidly generated. The gas enters the airbag 111 through the first opening 202 and the second opening 110, causing the airbag 111 to expand rapidly and form a buffer barrier between the front of the vehicle and the object to be detected, thereby reducing the collision force of the vehicle on the object to be detected.

[0048] Furthermore, the ejection assembly 12 includes a push plate 121 and a drive member 122. The push plate 121 is mounted on the drive member 122, which is disposed on the vehicle body. The drive member 122 is electrically connected to the control assembly. The push plate 121 faces the airbag 111, and the drive member 122 is used to drive the push plate 121 to move so that the airbag 111 is relatively away from the front bumper 20 of the vehicle. The push plate 121 quickly ejects the airbag 111 from the front bumper 20 of the vehicle, preventing the airbag 111 from being partially stuck in the position of the front bumper 20, allowing the airbag 111 to inflate quickly and increasing the effective buffer area of ​​the airbag 111.

[0049] In one embodiment, the push plate 121 can be configured as a spring. When the vehicle is driving normally, the spring is in a compressed state. When the control component receives the signal to pop up the airbag assembly 11, the drive component 122 releases the spring. Under its own elastic force, the spring pops the airbag 111 from the installation position of the front bumper 20 of the vehicle to the outside of the front bumper 20. At the same time, the airbag 111 inflates rapidly to form an effective buffer between the front of the vehicle and the object to be detected.

[0050] Furthermore, the vehicle also includes a trigger button 40, which is located on the vehicle's steering wheel and is electrically connected to the control component and the airbag assembly 11. The trigger button can be used by the driver to manually issue a control command to the control component according to the actual situation, causing the ejection assembly 12 to deploy the airbag assembly 11 and causing the airbag assembly 11 to provide cushioning protection against objects to be detected outside the vehicle.

[0051] By adding the activation timing of the active intervention safety protection component 10 based on human judgment, the safety protection effect on the tested component is further enhanced, and the flexibility of use is improved.

[0052] In another embodiment of this application, the trigger button 40 has an anti-accidental touch structure. The anti-accidental touch structure prevents accidental pressing of the trigger button 40, thereby improving the reliability of the safety protection component 10 during use.

[0053] In another embodiment of this application, the control component can drive the ejection component 12 and the airbag component 11 after the trigger button 40 is pressed three times, so as to reduce the problem of human error or accidental touch of the trigger button 40, thereby improving the reliability of the safety protection component 10 during use.

[0054] Furthermore, the vehicle includes a front bumper, and the airbag assembly 11 includes a mounting base 113 and a cover 114. The mounting base 113 forms a fixing cavity 131, which includes a third opening 3. The cover 114 is detachably sealed to the third opening 3. The airbag 111 and the air supply component are disposed within the fixing cavity 131, with the airbag 111 facing the third opening 3. By disposing the airbag 111 and the air supply component within the fixing cavity 131, with the airbag 111 facing the third opening 3, the elastic component can deploy the airbag 111 from the fixing cavity 131 through the third opening 3.

[0055] In a specific application scenario, when the detection mechanism 30 detects a signal that may lead to a collision, or when the trigger button 40 is pressed, the control component receives an instruction to activate the safety protection component 10. It can then control the elastic component to eject the airbag component 11 from the third opening 3. Under the elastic force of the elastic component and the resistance of the airbag component 11, the cover 114 opens the third opening 3, and the airbag 111 deploys. Simultaneously, the air supply component inflates the airbag 111, causing it to rapidly expand to protect against collisions.

[0056] In one embodiment of this application, the steering component of the ejection assembly 12 can adjust the orientation of the airbag 111 within the third opening 3, thereby controlling the direction in which the ejection assembly 12 ejects the airbag 111 from the third opening 3, so as to ultimately control the inflation position and direction of the airbag 111 and improve the buffering effect between the vehicle and the object to be detected.

[0057] refer to Figure 5 As shown, furthermore, the two ends of the cover 114 are respectively provided with a rotating member 4 and a snap-fit ​​member 5. The cover 114 is rotatably connected to the fixed base 113 through the rotating member 4, and the snap-fit ​​member 5 is elastically snapped into the fixed base 113. Furthermore, when the cover 114 is opened relative to the third opening 3, it can still be connected to the fixed base 113. The cover 114 is opened from the position where the snap-fit ​​member 5 is elastically snapped into the fixed base 113, and then rotates along the rotating member 4 to prevent the cover 114 from falling off the fixed base 113 and flying out of the fixed base 113 under the action of the elastic component, etc., thereby improving the safety protection effect of the test piece.

[0058] refer to Figure 6 As shown, in order to achieve the above objectives, in a second aspect, embodiments of this application provide a vehicle control method for controlling the vehicle, the vehicle control method comprising:

[0059] The vehicle's driving status data is acquired, including the vehicle's speed and the distance to objects in front of the vehicle. When the vehicle's speed is greater than a preset speed and / or the distance data is less than a preset distance threshold, the safety protection component 10 is activated to inflate the airbag 111.

[0060] As an example, the vehicle's driving status data can be detected by the detection mechanism 30. The vehicle's driving status data includes the distance between the vehicle and the object to be detected, the vehicle's driving speed, and the location of the object to be detected. When the vehicle speed exceeds a preset value and the distance between the vehicle and the object to be detected is less than a preset distance, the detected location information of the object to be detected is transmitted to the control component. The control component controls the steering component to drive the airbag component 11 to rotate, so that the airbag component 11 faces the location of the object to be detected. At the same time, the airbag component 11 is deployed to protect the object to be detected, reduce the collision force of the vehicle on the object to be detected, and reduce the damage to the object to be detected.

[0061] Furthermore, the driving status data also includes obtaining the activation status of the trigger button 40. When the trigger button 40 meets the preset trigger conditions, the protective component is activated to inflate the airbag 111.

[0062] As an example, the preset trigger condition can be set to trigger button 40 being pressed three times. If trigger button 40 is pressed three times, it is determined that trigger button 40 is in the activated state. The control component controls the safety protection component 10 to activate, thereby driving the ejection component 12 and the airbag component 11. The airbag component 11 improves the collision buffering effect on objects in front of the vehicle, reducing damage to objects in front of the vehicle. This reduces the problem of accidental operation or touch of trigger button 40 by human error, thereby improving the reliability of the safety protection component 10 during use.
