DETAILED DESCRIPTION

[0050] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0051] In related technologies, the main movement of vehicle-mounted ceiling screens is flipping or flipping + sliding. The main effect is that they are retracted into the vehicle roof when not in use, and flipped downward to a direction suitable for the passenger's viewing angle when in use.

[0052] The movement of this type of ceiling screen must include rotational movement, such as Figure 1 As shown, when the display screen rotates, an angle is formed between the display screen and the connecting rod. When the angle decreases, a parts clamping condition occurs. In addition, a clamping area is also formed between the edge of the display screen frame and the display screen mounting bracket. At this time, if objects or passenger limbs appear in the clamping area, a safety problem will arise.

[0053] In order to solve the above problems, the first embodiment of the present invention proposes a protection control system, which can detect and identify potential safety hazards that may exist during user use and perform protection control to reduce the risk of users being pinched during use.

[0054] Reference below Figure 1 The protection control system 100 according to an embodiment of the present invention is described. The protection control system 100 is used for a display screen structure with a rotation function. The protection control system 100 includes a sensor module 10 and a control module 20 .

[0055] Among them, the sensor module 10 is set in the display screen structure, and is used to collect obstacle information around the display screen structure; the control module 20 is connected to the sensor module 10, and the control module 20 is used to perform protection control according to the obstacle information.

[0056] Specifically, when a display screen with a rotating function is in motion, an angle is formed between the display screen and the connecting rod. When the angle decreases, a parts clamping condition occurs, and a clamping area is also formed between the edge of the display frame and the display screen mounting bracket. At this time, if objects or passenger limbs appear in the clamping area, a safety problem will arise. Therefore, the present application uses the sensor module 10 to quickly detect obstacles around the display screen structure that may affect its rotation to obtain obstacle information. The obstacle information may include the distance information, position information or shape information of the obstacle, etc. The obstacle information is sent to the control module 20, and the control module 20 determines whether there are safety hazards during the use of the display screen based on the obstacle information. If there are safety hazards, protective control can be carried out in time to reduce the risk of users being pinched during use. The sensor module 10 may include multiple sensors to detect different obstacle information. For example, the sensor module 10 may include an infrared sensor, a laser radar, a pressure sensor, etc., which are not specifically limited here.

[0057] According to the protection control system 100 of an embodiment of the present invention, during the use of the display screen, the sensor module 10 is used to quickly detect obstacles around the display screen structure to detect potential safety hazards. Based on the connection between the sensor module 10 and the control module 20, the control module 20 receives obstacle information and performs protection control before the safety hazard occurs, thereby reducing the risk of users being pinched during use.

[0058] In some embodiments, the sensing module 10 includes a contactless sensor and / or a contact sensor.

[0059] Specifically, the non-contact sensor is not affected by physical contact. Without direct contact with the obstacle, it can detect the existence and position of the obstacle and other information, and then detect whether there are obstacles around the display screen structure that may affect the rotation of the display screen, so as to detect potential safety hazards and reduce the risk of user injury. If only relying on contact sensors, it may lead to insufficient protection control, and obstacle information is collected only after the user is injured. Therefore, the sensing module can also include a contact sensor. The contact sensor obtains obstacle information by making physical contact with the obstacle, and then detects whether there are obstacles around the display screen structure that may affect the rotation of the display screen, which can detect potential safety hazards and reduce the risk of user injury.

[0060] In some embodiments, the non-contact sensor includes one or more of a non-contact capacitive sensor, an infrared sensor, an ultrasonic sensor, a grating sensor, and a laser ranging sensor.

[0061] Specifically, non-contact capacitive sensors can integrate electric fields. When a human body or a conductive object enters its detection range, the electric field around the non-contact capacitive sensor will change, resulting in a change in the capacitance value. Infrared sensors can use the emission and reception of infrared rays to detect obstacles. Ultrasonic sensors measure distance and detect obstacles by emitting ultrasonic waves and receiving reflected waves. The detection angle range of ultrasonic sensors is beneficial for covering the blind spots of linear scanning, thereby making up for the limitations of linear scanning of other sensors. Grating sensors use a transmitter to emit a series of light beams, which are then received by a receiver. When an obstacle enters the grating area, it will block part of the light beam, thereby triggering the grating sensor to send a signal. Laser ranging sensors use laser beams to measure the distance to the target object.

[0062] Based on different requirements for obstacle detection, the non-contact sensor can include only one of the non-contact capacitive sensor, infrared sensor, ultrasonic sensor, grating sensor and laser ranging sensor; or it can include any two or more of the non-contact capacitive sensor, infrared sensor, ultrasonic sensor, grating sensor and laser ranging sensor in combination, so as to give full play to the advantages of each sensor based on different detection requirements and improve user safety. Among them, the position of the non-contact sensor can be designed and arranged according to the characteristics of different sensors. In some embodiments, the display screen structure includes a display screen; the non-contact sensor includes at least one non-contact capacitive sensor, and the at least one non-contact capacitive sensor is disposed on the display screen.

[0063] Specifically, at least one non-contact capacitive sensor is set on the display screen to detect obstacles close to the display screen. When a person or object approaches the front of the display screen, the non-contact capacitive sensor can detect the change in capacitance value, thereby providing obstacle information to the control module for protective control.

[0064] In some embodiments, there are multiple non-contact capacitive sensors, some of which are evenly arranged at the four edges of the front of the display screen, and another part of which are evenly arranged at the four side frames of the display screen.

[0065] Specifically, such as Figure 2 As shown in a, non-contact capacitive sensors 21 are arranged equidistantly around the edge of the display screen 1. Figure 2 As shown in FIG. 2 , another part of the non-contact capacitive sensors 22 are evenly arranged at the four side frames of the display screen. The non-contact capacitive sensors 21 and the non-contact capacitive sensors 22 can be optimized and adjusted according to the specific size of the display screen 1. By arranging the non-contact capacitive sensors 21 and the non-contact capacitive sensors 22 on the front of the display screen 1 and the screen frame, it is beneficial to integrate the electric field, which can cover the detection around the edge of the screen and can detect the approach of a human body or a conductive object.

[0066] In some embodiments, the display screen structure includes a display screen and a mounting bracket for accommodating the display screen; the infrared sensor is disposed on the mounting bracket, and / or the infrared sensor is disposed on the display screen.

[0067] Specifically, such as Figure 3 As shown, the display screen structure 200 also includes a display screen 1 and a mounting bracket 3 for the display screen. The infrared sensor 4 is set on the mounting bracket 3. The stable structure of the mounting bracket 3 can be used to keep the infrared sensor 4 in a fixed position and angle, so that obstacles around the display structure can be detected more accurately. Alternatively, the infrared sensor 4 is set on the display screen 1, which can more directly detect obstacles close to the display screen 1 and quickly detect obstacle information, for example, Figure 3 As shown, two rows of infrared sensors 4 are arranged on the mounting bracket 3, and the arrangement positions are along the straight areas on both sides of the display screen, which is beneficial to covering the fully closed area of ​​the display screen 1; alternatively, infrared sensors are installed on the mounting bracket 3 and the display screen 1 at the same time, which can expand the range of obstacle detection and reduce detection blind spots.

[0068] In some embodiments, the infrared sensor includes at least one infrared transmitter and at least one infrared receiver, and the at least one infrared transmitter and the at least one infrared receiver are arranged opposite to each other; at least one infrared transmitter is located on the first short side of the front of the mounting bracket and is arranged close to the side of the display screen, and at least one infrared receiver is located on the second short side of the front of the mounting bracket and is arranged close to the side of the display screen, wherein the first short side and the second short side are arranged opposite to each other.

[0069] Specifically, such as Figure 4 As shown, the infrared sensor 4 includes at least one infrared transmitter 41 and at least one infrared receiver 42. A light curtain can be formed between the infrared transmitter 41 and the infrared receiver 42. Once any light beam is blocked, it can be determined that there is an obstacle and the obstacle information can be sent to the control module 20. Figure 4 As shown, at least one infrared transmitter 41 is located on the first short side of the front of the mounting bracket 3 and is arranged close to the side of the display screen 1, and at least one infrared receiver 42 is located on the second short side of the front of the mounting bracket 3 and is arranged close to the side of the display screen 1. The arrangement position is along the straight line area of ​​the short sides on both sides of the display screen 1, which is beneficial to covering the fully closed area of ​​the display screen 1.

[0070] In some embodiments, an infrared stealth coating is formed on the outer housing of the display screen.

[0071] Specifically, in order to prevent the infrared sensor 4 from judging the display screen 1 as an obstacle during the movement of the display screen 1, an infrared stealth material can be coated on the outer shell of the display screen 1. The stealth material is a material with high infrared transmittance that can reduce or eliminate the visibility of objects in the infrared spectrum, and is used to reduce the probability of the target being discovered by the infrared detector.

[0072] In some embodiments, the infrared sensor includes at least one infrared transmitter and at least one infrared receiver, the at least one infrared transmitter and the at least one infrared receiver are arranged opposite to each other, and the at least one infrared transmitter and the at least one infrared receiver are both located on the back of the display screen.

[0073] Specifically, at least one infrared transmitter and at least one infrared receiver are both located on the back of the display screen 1 to avoid affecting the appearance and display effect of the front of the display screen 1 and not affecting the user's experience. In some embodiments, the display screen structure includes a display screen and a mounting bracket for accommodating the display screen; the non-contact sensor includes at least one ultrasonic sensor, and the at least one ultrasonic sensor is disposed on the mounting bracket.

[0074] Specifically, the ultrasonic sensor 5 is arranged on the mounting bracket 3, and the stability of the mounting bracket 3 can be utilized to avoid the position of the ultrasonic sensor 5 being shifted due to vibration during vehicle driving, affecting the detection of obstacles and ultimately causing injuries to the user during use.

[0075] In some embodiments, the non-contact sensor includes four ultrasonic sensors, and the four ultrasonic sensors are respectively located at four diagonal positions on the front side of the mounting bracket.

[0076] Specifically, such as Figure 4 As shown, four ultrasonic sensors 5 are arranged at four diagonal positions on the front of the mounting bracket 3. Each ultrasonic sensor 5 can perform wide-angle detection within a range of 90°. Based on the above arrangement, when an obstacle approaches the detection area, it can be directly detected. In addition, due to the detection angle range of the ultrasonic sensor 5 and its arrangement position, the blind area of ​​the linear scanning can be covered, making up for the limitations of the linear scanning of other sensors.

[0077] In some embodiments, the display screen structure includes a display screen and a mounting bracket for accommodating the display screen; the grating sensor is disposed on the mounting bracket, and / or the grating sensor is disposed on the back of the display screen.

[0078] Specifically, such as Figure 5 As shown, the grating sensor 6 is arranged on the mounting bracket 3, and the stability of the mounting bracket 3 can be utilized to avoid the position of the grating sensor 6 being offset or the signal being distorted due to vibration during vehicle driving. At the same time, electromagnetic interference can be isolated to avoid the detection of obstacles affected by the external environment of the vehicle, which ultimately causes injuries to the user during use; the grating sensor 6 is arranged on the back of the display screen 1, and can detect obstacles close to the display screen 1 at close range, and send obstacle information in time to avoid injuries to the user during use, and does not affect the appearance and display effect of the front of the display screen 1, and does not affect the user's experience.

[0079] In some embodiments, the display screen structure includes a display screen and a mounting bracket for accommodating the display screen; the laser ranging sensor is disposed on the mounting bracket, and / or the laser ranging sensor is disposed on the back of the display screen.

[0080] Specifically, such as Figure 6As shown, the laser rangefinder 7 is arranged on the mounting bracket 3, and the stability of the mounting bracket 3 can be utilized to avoid the position of the laser rangefinder 7 being offset or the signal being distorted due to vibration during vehicle driving. At the same time, electromagnetic interference is isolated to avoid the detection of obstacles being affected by the external environment of the vehicle, which ultimately causes injuries to the user during use. The laser rangefinder 7 is arranged on the back of the display screen 1, and can detect obstacles close to the display screen 1 at close range, and send obstacle information in time to avoid injuries to the user during use. It does not affect the appearance and display effect of the front of the display screen 1, and does not affect the user's experience.

[0081] In some embodiments, the touch sensor includes a pressure sensor, a touch capacitance sensor, and / or a pressure sensitive film.

[0082] Specifically, when an external force acts on the pressure sensor, the sensing element inside the pressure sensor will deform, causing its electrical characteristics to change. By measuring the change in electrical characteristics, the magnitude of the external force acting on the pressure sensor can be calculated and sent to the control module 20. This can be used to determine the tolerance of the human body and perform protective control before the user is injured. The contact capacitance sensor can detect the contact of an object by using the change in capacitance. When the user's body contacts the contact capacitance sensor, its capacitance value will change and be sent to the control module 20. That is, the change in capacitance value can be measured to determine whether there is an object in contact and the location of the contact, and protective control can be performed. When the pressure sensing film is subjected to pressure, the conductive particles inside it will be displaced, causing the resistance of the pressure sensing film to change. The resistance is sent to the control module 20. That is, by measuring the change in resistance, the magnitude and distribution of the pressure can be determined. This can be determined based on the tolerance of the human body and protective control can be performed before the user is injured.

[0083] In some embodiments, the display screen structure includes a display screen and a mounting bracket for accommodating the display screen; the touch sensor includes at least one pressure sensor, and the at least one pressure sensor is disposed on the mounting bracket.

[0084] Specifically, if the non-contact sensor fails to detect an obstacle, the contact sensor can serve as a final anti-pinch protection measure. The pressure sensor, mounted on mounting bracket 3, detects the pressure applied to the human body and transmits the pressure value to control module 20. If the pressure exceeds the human body's tolerance, the user is at risk of injury and protective measures should be taken promptly. The number and installation locations of the pressure sensors can be controlled based on actual conditions. Choosing the appropriate number and installation locations can avoid detection blind spots and improve the reliability of the protective control system.

[0085] In some embodiments, there are multiple pressure sensors, and the multiple pressure sensors are evenly arranged on the inner sides of the four side frames of the mounting bracket.

[0086] Specifically, the number and arrangement of the pressure sensors 8 are as follows: Figure 7 As shown, the pressure sensor 8 is arranged on the mounting bracket 3 and embedded in the gap between the mounting bracket 3 and the frame of the display screen 1. The pressure sensors are arranged equidistantly on the four surfaces of the mounting bracket 3 to cover the closed area of ​​the display screen 1.

[0087] In some embodiments, the display screen structure includes a display screen and a mounting bracket for accommodating the display screen; the contact capacitance sensor is arranged on the display screen and / or the mounting bracket; and the pressure sensing film is arranged on the display screen and / or the mounting bracket.

[0088] Specifically, the contact capacitive sensor can detect whether there is contact with an obstacle and the contact position, so that an early warning can be issued when an obstacle is detected, thereby improving the response speed of the protection control system; the pressure sensing film can detect the contact pressure and contact position of the obstacle, and take timely protective control measures when the pressure exceeds the tolerance level of the human body.

[0089] The contact capacitance sensor and the pressure sensing film are simultaneously arranged on the display screen 1 to avoid false detection of obstacles. The contact capacitance sensor and the pressure sensing film are simultaneously arranged on the mounting bracket 3 to take advantage of the stability of the mounting bracket 3 to avoid position deviation caused by vibration during vehicle driving, thereby affecting the detection of obstacles. When the contact capacitance sensor is arranged on the display screen 1 and the pressure sensing film is arranged on the mounting bracket 3, or when the contact capacitance sensor is arranged on the mounting bracket 3 and the pressure sensing film is arranged on the display screen 1, the range of obstacle detection can be expanded and the detection blind area can be reduced.

[0090] In some embodiments, as Figure 8 As shown, the display screen structure 200 includes a display screen 1 , a mounting bracket 3 and a driving assembly 9 .

[0091] Among them, the display screen 1 is connected to the mounting bracket 3 through the connecting component 8, and the connecting component 10 drives the display screen 1 to rotate under the drive of the driving component 9; the control module 20 is connected to the driving component 9, and the control module 20 is used to control the driving state of the driving component 9 according to the obstacle information to perform protection control.

[0092] Specifically, the control module 20 identifies the obstacle information and determines whether the obstacle is in contact, the distance to the obstacle, the pressure, etc., thereby controlling the driving state corresponding to the operation of the driving component 7. For example, if the obstacle is not in contact, the driving component 9 can be controlled to be in a driving state of deceleration; or, when the obstacle is in contact but does not cause pinching, the driving component 7 can be controlled to be in a driving state of stopping; or, when the obstacle is in contact and causes pinching, the driving component 9 can be controlled to be in a driving state of reverse operation.

[0093] In some embodiments, as Figure 1 As shown, the protection control system 100 further includes an alarm module 30 .

[0094] The alarm module 30 is connected to the control module 20 , and is used to issue an alarm prompt under the control of the control module 20 .

[0095] Specifically, when the control module 20 performs protection control according to the obstacle information, the alarm module 30 alerts the user and displays on the display screen that the current abnormal state is in progress until the abnormality is resolved.

[0096] The second embodiment of the present invention proposes a protection control method, which includes steps S1 and S2. The specific steps are as follows: Figure 9 shown.

[0097] Step S1: Obtain obstacle information around the display screen structure.

[0098] Specifically, during the movement, an angle is formed between the display screen and the connecting rod. When the angle decreases, a parts clamping condition occurs, and a clamping area is also formed between the edge of the display screen frame and the display screen mounting bracket. At this time, if objects or passenger limbs appear in the clamping area, a safety problem will arise. Obstacles around the display screen structure that may affect its rotation are quickly detected to obtain obstacle information to avoid objects or passenger limbs appearing in the clamping area. The obstacle information may include distance information, position information or shape information of the obstacle.

[0099] Step S2: Perform protection control based on obstacle information.

[0100] Specifically, based on the recognition of obstacle information, it can determine whether the obstacle is in contact, the distance of the obstacle, the pressure, etc., so as to perform protective control to reduce the risk of users being pinched during use.

[0101] According to the protection control method of the embodiment of the present invention, obstacles around the display screen structure are quickly identified to detect potential safety hazards, and then protection control is performed before the safety hazards occur, thereby reducing the risk of users being pinched during use.

[0102] In some embodiments, the obstacle information includes obstacle distance information collected by a non-contact sensor and / or contact pressure information collected by a contact sensor.

[0103] Specifically, the non-contact sensor is not affected by physical contact. Without direct contact with the obstacle, it can detect the obstacle distance information, and then determine whether there are obstacles around the display screen structure that may affect the rotation of the display screen, so as to detect potential safety hazards and reduce the risk of user injury. However, relying solely on obstacle distance information may result in untimely protection control, and the obstacle distance information is not collected until the user is injured. Therefore, the obstacle information also includes contact pressure information. The contact sensor obtains contact pressure information by making physical contact with the obstacle, and then can detect whether there are obstacles around the display screen structure that may affect the rotation of the display screen, which can detect potential safety hazards and reduce the risk of user injury.

[0104] In some embodiments, protection control is performed when the obstacle distance information meets the protection monitoring conditions.

[0105] Specifically, based on the recognition of obstacle information, it can be determined whether the user is at risk of being pinched, that is, whether the protection monitoring conditions are met, so as to perform protection control to reduce the risk of users being pinched during use.

[0106] In some embodiments, the obstacle distance information includes one or more of capacitance change information collected by a non-contact capacitance sensor, infrared light information collected by an infrared sensor, and ultrasonic information collected by an ultrasonic sensor.

[0107] Specifically, when a human body or a conductive object enters its detection range, the electric field around the non-contact capacitive sensor will change, resulting in a change in the capacitance value. The position of the obstacle can be detected through the capacitance change information; the infrared sensor can use the emission and reception of infrared rays to detect obstacles, and the position of the obstacle can be detected through the infrared light information; the ultrasonic sensor measures distance and detects obstacles by emitting ultrasonic waves and receiving reflected waves, and the position of the obstacle can be detected through the ultrasonic information.

[0108] Based on different requirements for obstacle detection, the obstacle distance information may include any one of capacitance change information, infrared light information, and ultrasonic information; or, include capacitance change information and infrared light information, capacitance change information and ultrasonic information, or infrared light information and ultrasonic information at the same time; or include capacitance change information, infrared light information, and ultrasonic information at the same time.

[0109] In some embodiments, the first-level protection control is performed when the protection monitoring condition is determining that the capacitance change information indicates that an obstacle is close to the display screen structure and / or determining that the ultrasonic information indicates that an obstacle is close to the display screen structure.

[0110] Specifically, when it is determined that an obstacle is approaching, protective control is required to avoid pinching accidents. However, the possibility of a pinching accident caused by the approaching obstacle is not high. In order to avoid false triggering, first-level protective control can be performed, using multi-level response logic, which is beneficial to prevent false triggering of the protective control function in scenarios such as vehicle body vibration and flying insects accidentally entering the closed area of ​​the screen.

[0111] In some embodiments, the first level protection control is to reduce the driving speed of the driving component in the display screen structure.

[0112] Specifically, when it is determined that an obstacle is approaching, protective control is required to avoid a pinching accident. However, the possibility of a pinching accident caused by the approaching obstacle is small. It is only necessary to reduce the driving speed of the driving component in the display structure, take protective control in advance and avoid false triggering.

[0113] In some embodiments, secondary protection control is performed when the protection monitoring condition is to determine that the infrared light information indicates that the obstacle is located in the screen closed area of ​​the display screen structure.

[0114] Specifically, if it is determined based on infrared light information that the obstacle is in the screen closed area of ​​the display screen structure, if the driving component continues to drive, it may cause the user's limbs to be pinched, and further protective control, namely secondary protective control, should be taken.

[0115] In some embodiments, the secondary protection control is to control the driving component of the display screen structure to stop driving.

[0116] Specifically, if it is determined based on infrared light information that the obstacle is in the screen closed area of ​​the display screen structure, if the driving component continues to drive, it may cause the user's limbs to be pinched, and the driving component of the display screen structure should be controlled to stop driving in time.

[0117] In some embodiments, the third level protection control is performed when it is determined that the contact pressure information is greater than a preset pressure threshold.

[0118] Specifically, if the contact pressure information is determined to be greater than a preset pressure threshold, then the obstacle has entered the screen's enclosed area and is squeezing the display screen and mounting bracket, and the user's limbs have been pinched. Further protective control measures, namely, level 3 protective control, should be implemented. The preset pressure threshold can be dynamically set based on the human body's tolerance level. For example, the preset pressure threshold can be set to 60N, 65N, or 70N, etc., and no specific restrictions are set here.

[0119] In some embodiments, the third-level protection control is to control the driving component of the display screen structure to drive the display screen to open at a preset angle.

[0120] Specifically, if it is determined that the contact pressure information is greater than the preset pressure threshold, then the obstacle has entered the closed area of ​​the screen and is squeezed between the display screen and the mounting bracket, and the user's limbs have been pinched. If the driving component continues to drive or stops driving, the user's limbs are still in a squeezed state. Therefore, the driving component that controls the display screen structure drives the display screen to open at a preset angle, so that the obstacle no longer has a squeezing problem, thereby achieving a protective effect.

[0121] Reference below Figure 10 The protection control method of an embodiment of the present invention is described as follows. The specific steps are as follows.

[0122] Step S3, start, Step S4: the control module controls the driving component to drive the display screen to rotate.

[0123] Step S5: Check whether the obstacle information indicates that an obstacle is approaching. If so, go to step S7; if not, go to step S6.

[0124] In step S6, the driving assembly drives the display screen to rotate to a designated position, and then step S14 is executed.

[0125] Step S7: reducing the driving speed of the driving component in the display screen structure.

[0126] Step S8: Check whether the obstacle information indicates that the obstacle is located in the closed screen area of ​​the display screen structure. If so, execute step S9; if not, execute step S6.

[0127] Step S9: controlling the driving component of the display screen structure to stop driving.

[0128] Step S10: Check whether the obstacle information indicates that the obstacle has been removed. If so, go to step S6; if not, go to step S11.

[0129] In step S11 , it is determined whether the contact pressure information is greater than a preset pressure threshold. If so, step S12 is executed; if not, step S9 is executed.

[0130] Step S12: controlling the driving component of the display screen structure to drive the display screen to open at a preset angle.

[0131] Step S13: Check whether the user chooses to initialize. If so, go to step S4; if not, go to step S14.

[0132] Step S14, end.
