Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0030] Figure 1 A schematic block diagram of a screen saver system according to an embodiment of this application is shown. See also... Figure 1 The screen protection system includes a controller 100, a first acquisition unit 200, a second acquisition unit 300, and a protection unit 400. The first acquisition unit 200, the second acquisition unit 300, and the protection unit 400 are all electrically connected to the controller 100.

[0031] Specifically, the first acquisition unit 200 acquires the gas velocity around the vehicle and transmits the gas velocity to the controller 100. The second acquisition unit 300 acquires the gas pressure around the vehicle and transmits the gas pressure to the controller 100.

[0032] When a vehicle brakes suddenly or an object approaches rapidly nearby, the gas velocity and pressure around the vehicle change rapidly. Therefore, by monitoring the rates of change in gas velocity and pressure around the vehicle, it's possible to determine if emergency braking has occurred or if there is a potential collision hazard. Upon receiving the gas velocity and pressure data, the controller 100 calculates a first rate of change in gas velocity and a second rate of change in gas pressure, comparing the first rate of change with a first preset value and the second rate of change with a second preset value. When both the first rate of change and the second rate of change are greater than the first preset value, it indicates that emergency braking has occurred or there is a potential collision hazard. In this case, the controller 100 activates the protection unit 400, which shields the screen. If a collision occurs and the screen breaks, the glass shards from the screen breakage are blocked by the protection unit 400, preventing them from splashing onto the occupants and protecting them.

[0033] It should be noted that designers can set the specific values ​​of the first and second preset values ​​according to the actual situation.

[0034] For example, the first preset value is 35 ml / min 2 The second preset value is 5 Pa / s. The gas velocity obtained at the first sampling time is V1, the gas pressure is p1, the volume velocity obtained at the second sampling time is V2, the gas pressure is p2, and the sampling period is t.

[0035] If (v1-v2) / t > 35 ml / min 2 And (p1-p2) / t > 5 N / m 2 At time *s, the controller 100 activates the protection unit 400, causing the protection unit 400 to shield the screen. If a collision occurs and the screen breaks, the glass shards from the screen breakage are blocked by the protection unit 400, preventing them from splashing onto the occupants and thus protecting them.

[0036] If only one gas flow sensor is installed on the vehicle during operation, and if foreign objects (such as plastic bags, cardboard boxes, etc.) approach the gas flow sensor, the first rate of change of the gas flow rate collected by the gas flow sensor will be greater than the first preset value. At this time, the controller 100 will determine that the vehicle is undergoing emergency braking or there is a potential collision risk. This results in a misjudgment by the controller 100, which in turn leads to the erroneous activation of the protection unit 400.

[0037] To address the aforementioned issues, in one embodiment of this application, the first acquisition unit 200 includes a gas flow sensor, which is distributed on at least one of the front, rear, left, and right sides of the vehicle, and all gas flow sensors are electrically connected to the controller 100.

[0038] Specifically, each gas flow sensor collects the gas velocity around the vehicle and transmits it to the controller 100. The controller 100 calculates the first rate of change of each gas velocity. When all the first rates of change are greater than a first preset value and the second rate of change is greater than a second preset value, it indicates that the vehicle is undergoing emergency braking or there is a potential collision risk. At this time, the controller 100 controls the control protection unit 400 to activate, causing the protection unit 400 to shield the screen. If the vehicle collides and the screen breaks, the glass shards generated by the screen breakage are blocked by the protection unit 400 and cannot fly onto the occupants, thus protecting them. Only when all the first rates of change are greater than the first preset value can the controller 100 determine that the vehicle has undergone emergency braking or there is a potential collision risk, avoiding incorrect judgments by the controller 100 and incorrect activation of the protection unit 400.

[0039] By setting up multiple gas flow sensors and distributing them on at least one of the front, rear, left, and right sides of the vehicle, the gas flow sensors can collect gas flow velocity data at multiple locations on the vehicle, thereby improving the accuracy of vehicle detection.

[0040] It should be noted that designers can set the specific number of gas flow sensors according to the actual situation. For example, four gas flow sensors can be installed, one each on the front, rear, left, and right sides of the vehicle.

[0041] If only one air pressure sensor is installed on the vehicle during driving, and if foreign objects (such as plastic bags, cardboard boxes, etc.) approach the air pressure sensor, the second rate of change of gas pressure collected by the air pressure sensor will be greater than the second preset value. At this time, the controller 100 will determine that the vehicle has undergone emergency braking or there is a potential collision risk. This results in a misjudgment by the controller 100, which in turn leads to the erroneous activation of the protection unit 400.

[0042] To address the aforementioned issues, in one embodiment of this application, the second acquisition unit 300 includes a bar pressure sensor, which is distributed on at least one of the front, rear, left, and right sides of the vehicle, and all bar pressure sensors are electrically connected to the controller 100.

[0043] Specifically, each air pressure sensor collects the gas pressure around the vehicle and transmits it to the controller 100. The controller 100 calculates the second rate of change of each gas pressure. When all the first rates of change are greater than a first preset value and all the second rates of change are greater than a second preset value, it indicates that the vehicle is undergoing emergency braking or there is a potential collision risk. At this time, the controller 100 activates the protection unit 400, causing the protection unit 400 to shield the screen. If a collision occurs and the screen breaks, the glass shards generated by the screen breakage are blocked by the protection unit 400 and cannot splash onto the occupants, thus protecting them.

[0044] Only when all the second change rates are greater than the second preset value can the controller 100 determine that the vehicle has undergone emergency braking or there is a potential collision risk, thus avoiding incorrect judgment by the controller 100 and incorrect activation of the protection unit 400.

[0045] By setting up multiple air pressure sensors and distributing them on at least one of the front, rear, left, and right sides of the vehicle, the air pressure sensors can collect gas pressure data at multiple locations on the vehicle, improving the accuracy of vehicle detection.

[0046] It should be noted that designers can set the specific number of air pressure sensors according to the actual situation. For example, four air pressure sensors can be installed, one on each of the front, rear, left, and right sides of the vehicle.

[0047] Figure 2 A schematic diagram of the structure of a protection unit provided in an embodiment of this application is shown. See also... Figure 2 As shown, the protection unit 400 includes a track 401, a baffle 402 and a motion component 403. The track 401 is disposed on both sides of the screen 404. The baffle 402 is slidably connected to the track 401. The motion component 403 is connected to the baffle 402 and electrically connected to the controller 100.

[0048] Specifically, the controller 100 controls the motion component 403 to move between a first position and a second position, and the motion component 403 drives the baffle 402 to move. When the motion component 403 is in the first position, the baffle 402 blocks the screen 404, and when the motion component 403 is in the second position, the baffle 402 avoids the screen 404.

[0049] For example, when the vehicle is driving normally, when the controller 100 controls the motion component 403 to the second position, the baffle 402 avoids the screen 404, allowing passengers to view the screen 404 normally. When the controller 100 determines that the vehicle is undergoing emergency braking or there is a potential collision risk, the controller 100 controls the motion component 403 to move from the second position to the first position. The movement of the motion component 403 causes the baffle 402 to move synchronously on the track 401. When the motion component 403 is in the first position, the baffle 402 blocks the screen 404. If the vehicle collides and the screen 404 is damaged, the debris from the broken screen 404 is blocked by the baffle 402 and cannot splash onto the passengers, thus protecting them.

[0050] For example, the baffle 402 includes a metal plate and a rubber plate, with the rubber plate adhered to or embedded in the metal plate. The metal plate can be made of iron, steel, aluminum, or copper. When the baffle 402 covers the screen 404, the metal plate faces the screen 404, and the rubber plate faces the occupants. The metal plate is characterized by high toughness and hardness; when a vehicle collision occurs, the metal plate will not break, and it can cover the screen 404 intact, thus protecting the occupants. The rubber plate faces the occupants; due to its elasticity, when the occupants impact the rubber plate, it can mitigate the impact force and reduce injury.

[0051] In one embodiment of this application, the motion component 403 includes an electric telescopic rod, the telescopic end of which is connected to the baffle 402, and the electric telescopic rod is electrically connected to the controller 100.

[0052] Specifically, the electric telescopic pole is installed on one side of the screen 404, and the controller 100 can control the extension or retraction of the telescopic end of the electric telescopic pole. When the vehicle is in normal operation, the controller 100 controls the telescopic end of the electric telescopic pole to be in the retracted state. At this time, the baffle 402 avoids the screen 404, allowing passengers to view the screen 404 normally. When the controller 100 determines that the vehicle is undergoing emergency braking or there is a potential collision hazard, the controller 100 controls the telescopic end of the electric telescopic pole to extend, thereby moving the baffle 402 on the guide rail, causing the baffle 402 to block the screen 404. If the vehicle collides and the screen 404 is damaged, the debris from the broken screen 404 is blocked by the baffle 402 and cannot splash onto the passengers, thus protecting them.

[0053] Existing screen protectors use airbags to inflate the screen, but airbag retraction is difficult after an emergency (such as emergency braking). The protection unit 400 in this application combines an electric telescopic rod and a baffle 402. When the vehicle brakes suddenly, the controller 100 extends the telescopic end of the electric telescopic rod, causing the baffle 402 to block the screen 404, preventing passengers from touching and damaging it. Once the vehicle has come to a stop, the controller 100 retracts the telescopic end of the electric telescopic rod, allowing the baffle 402 to avoid contact with the screen 404, thus enabling passengers to view the screen normally.

[0054] In one embodiment of this application, the motion component 403 includes a fixing member, an elastic component, and an electric snap-fit ​​component. The fixing member is disposed on the side of the screen 404. The first end of the elastic component is connected to the fixing member, and the second end of the elastic component is connected to the baffle 402. The elastic component is provided with a snap-fit ​​structure adapted to the electric snap-fit ​​component. The electric snap-fit ​​component is electrically connected to the controller 100.

[0055] Specifically, the controller 100 controls the electric latching assembly to move between the third and fourth positions. When the electric latching assembly is in the third position, it engages with the latching structure on the elastic component, and the elastic component is in a compressed state. At this time, the baffle 402 avoids the screen 404, allowing passengers to view the screen 404 normally. When the controller 100 determines that the vehicle is undergoing emergency braking or there is a potential collision hazard, the controller 100 controls the electric latching assembly to move to the fourth position. The electric latching assembly disengages from the latching structure on the elastic component, and the elastic component drives the baffle 402 to move, causing the baffle 402 to cover the screen 404. If the vehicle collides and the screen 404 breaks, the debris from the broken screen 404 is blocked by the baffle 402 and cannot splash onto the passengers, thus protecting them.

[0056] like Figure 3 As shown, the fastener includes a base 4031, and a groove 4032 is provided on the base 4031. The first end of the elastic component is fixedly connected to the bottom of the groove 4032. When the elastic component is in a compressed state, the elastic component is located in the groove 4032.

[0057] Specifically, the elastic component is set in the groove 4032. The inner wall of the groove 4032 can limit the position of the elastic component. When the electric snap-fit ​​component disengages from the snap-fit ​​structure on the elastic component, the elastic component can pop out along the extension direction of the groove 4032, thereby driving the baffle 402 to move, so that the baffle 402 can block the screen 404.

[0058] like Figure 3As shown, the electric snap-fit ​​assembly includes a motor 4033 and a snap-fit ​​4034. The shaft of the motor 4033 is connected to the snap-fit ​​4034, and the motor 4033 is electrically connected to the controller 100.

[0059] Specifically, the controller 100 controls the motor 4033 to move the latch 4034 between the fifth and sixth positions. When the vehicle is moving normally, the latch 4034 is in the fifth position, engaging with the locking structure on the elastic component, which is in a compressed state. At this time, the baffle 402 avoids the screen 404, allowing passengers to view the screen 404 normally. When the controller 100 determines that the vehicle is undergoing emergency braking or there is a potential collision risk, the controller 100 controls the motor 4033 to rotate, thereby moving the latch 4034 to the sixth position. The latch 4034 disengages from the locking structure on the elastic component, and the elastic component moves the baffle 402, causing the baffle 402 to cover the screen 404. If the vehicle collides and the screen 404 breaks, the debris from the broken screen 404 is blocked by the baffle 402 and cannot splash onto the passengers, thus protecting them.

[0060] like Figure 3 As shown, the elastic component includes a spring 4035 and a support plate 4036. The first end of the spring 4035 is connected to the fixing member, and the second end of the spring 4035 is connected to the baffle 402. The spring 4035 passes through the support plate 4036 and is fixedly connected to the support plate 4036. The support plate 4036 is provided with a snap-fit ​​structure adapted to the electric snap-fit ​​component.

[0061] Specifically, the support plate 4036 contacts the inner wall of the groove 4032, and the support plate 4036 can limit the extension or shortening of the spring 4035 along the extension direction of the groove 4032. When the vehicle is in normal driving, the buckle 4034 is in the fifth position, and the buckle 4034 is engaged with the snap-fit ​​structure on the support plate 4036. The spring 4035 is in a compressed state. At this time, the baffle 402 avoids the screen 404, and the passengers can view the screen 404 normally. When the controller 100 determines that the vehicle has undergone emergency braking or there is a potential collision risk, the controller 100 controls the motor 4033 to rotate, thereby driving the buckle 4034 to move to the sixth position. The buckle 4034 disengages from the snap-fit ​​structure on the support plate 4036, and the spring 4035 drives the baffle 402 to move, so that the baffle 402 blocks the screen 404. If the vehicle collides and the screen 404 is damaged, the fragments generated by the damage to the screen 404 are blocked by the baffle 402 and cannot fly onto the passengers, thus protecting them.

[0062] This application also provides a vehicle including the aforementioned screen protection system. During vehicle operation, a first acquisition unit collects the gas flow velocity around the vehicle and transmits the gas flow velocity to a controller. A second acquisition unit collects the gas pressure around the vehicle and transmits the gas pressure to the controller. The controller calculates a first rate of change of gas flow velocity and a second rate of change of gas pressure. When the first rate of change is greater than a first preset value and the second rate of change is greater than a second preset value, indicating an emergency braking situation or a potential collision, the controller activates the protection unit to shield the screen, preventing screen breakage and debris from splashing and injuring occupants.

[0063] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
