Description

Technical Field

[0001] The present invention relates to the technical field of vehicle safety, and in particular to a door-opening anti-collision monitoring system and a vehicle. Background Art

[0002] At present, with the improvement of living standards, there are more and more vehicles in society, which has also led to a continuous increase in traffic accidents. While constantly calling on drivers to pay attention to safe driving, the safety and reliability of the car itself should also be improved.

[0003] Among the many types of traffic accidents, there is one type that frequently occurs due to negligence of drivers and passengers. That is, when the car stops temporarily and passengers get off, they fail to observe the surrounding pedestrians and vehicles, thereby knocking down motorcycles, bicycles or electric vehicles coming from behind. Or the rear vehicle does not have time to react and hits the open car door, causing the rider to fall to the ground and cause injury. There may also be a car passing by in the adjacent lane, hitting or crushing the fallen cyclist, leading to more serious adverse consequences.

[0004] At present, detection radars are installed in the vehicle doors to address this situation. When the radar detects a vehicle coming from behind, it will sound an alarm or directly lock the door to reduce the damage caused by opening the door to the driver of the vehicle coming from behind.

[0005] However, since the radar is installed at the door position, and during the door opening process, the radar produces an angular offset following the door opening, the radar detection installed in the existing vehicle cannot always detect the rear vehicle, thereby failing to further reduce the probability of accidents.

[0006] Therefore, it is urgent to provide a door opening anti-collision monitoring system and a vehicle to solve the problems in the prior art to a certain extent. Summary of the Invention

[0007] The purpose of the present invention is to provide a door opening anti-collision monitoring system and a vehicle, so as to solve to a certain extent the problem that the existing door detection radar cannot always detect the vehicle coming from behind during the door opening process.

[0008] The present invention provides a door-opening anti-collision monitoring system for a vehicle, comprising a monitoring mechanism, the monitoring mechanism comprising a traction assembly, an engagement assembly and a first detection member; the traction assembly comprises a first traction member and a second traction member, the engagement assembly comprises a first engagement member and a second engagement member; one end of the first traction member is connected to the support column of the vehicle, and the other end is connected to the first position of the first engagement member, one end of the second traction member is connected to the door of the vehicle, and the other end is connected to the second position of the first engagement member, a telescopic section is formed on the second traction member to enable the second traction member to be extended or shortened; the first engagement member and the second engagement member are engaged with each other, and the first detection member is connected to the second engagement member, and the rotation of the first engagement member can drive the rotation of the second engagement member so that the detection surface of the first detection member is always facing the rear of the vehicle.

[0009] Among them, the door opening anti-collision monitoring system provided by the present invention also includes a second detection component, and the second detection component is arranged at the rear fender of the vehicle.

[0010] Specifically, the door opening anti-collision monitoring system provided by the present invention also includes a vehicle door locking device, which includes a locking mechanism and a driving mechanism. The driving mechanism is communicatively connected to the first detection member and the second detection member. The first detection member and the second detection member can send a signal to control the start of the driving mechanism to start the locking mechanism to lock the vehicle door.

[0011] Furthermore, the locking mechanism includes a limit member, a transmission member and a locking member; the driving mechanism is connected to the locking member to drive the locking member to move in a direction close to or away from the transmission member, the transmission member cooperates with the limit member, one end of the limit member is rotatably connected to the support column corresponding to the vehicle, and the other end is rotatably connected to the vehicle door, and the driving mechanism, the locking member and the transmission member are all arranged inside the vehicle door.

[0012] Furthermore, the limiting member is a rack, the transmission member is a gear, and a tooth portion is formed on a side of the locking member facing the transmission member, and the tooth portion is parallel to the limiting member.

[0013] Furthermore, there are two transmission members, which are relatively arranged on both sides of the limiting member. The locking member is arranged in a one-to-one correspondence with the transmission member, and the driving mechanism is arranged in a one-to-one correspondence with the locking member.

[0014] In which, the telescopic section is a spring, and the second traction member includes a first connecting section and a second connecting section, one end of the first connecting section is connected to the vehicle door, and the other end is connected to one end of the spring, the other end of the spring is connected to one end of the second connecting section, and the other end of the second connecting section is connected to the second position of the first engaging member.

[0015] Specifically, a contact piece is provided at the connecting end of the spring and the second connecting section, a sensing piece is provided in the vehicle door, and the contact piece is communicatively connected with the first detection piece. When the contact piece contacts the sensing piece, the contact piece controls the first detection piece to stop detection.

[0016] Furthermore, the first connecting section and the second connecting section are both metal rods, and the first traction member is a steel wire.

[0017] Compared with the existing technology, the door opening anti-collision monitoring system provided by the present invention has the following advantages:

[0018] The door-opening anti-collision monitoring system provided by the present invention is used for a vehicle and includes a monitoring mechanism, which includes a traction assembly, an engagement assembly and a first detection member; the traction assembly includes a first traction member and a second traction member, and the engagement assembly includes a first engagement member and a second engagement member; one end of the first traction member is connected to a support column of the vehicle, and the other end is connected to a first position of the first engagement member, one end of the second traction member is connected to a door of the vehicle, and the other end is connected to the second position of the first engagement member, and a telescopic section is formed on the second traction member to enable the second traction member to be extended or shortened; the first engagement member and the second engagement member are engaged with each other, and the first detection member is connected to the second engagement member, and the rotation of the first engagement member can drive the rotation of the second engagement member, so that the detection surface of the first detection member is always facing the rear of the vehicle.

[0019] From this analysis, it can be seen that by connecting one end of the first traction member to the support column and the other end to the first position of the first engaging member, and the first engaging member is connected to the vehicle door for rotation, when the vehicle door is opened, the first engaging member can be pulled to rotate by the first traction member. Since one end of the second traction member in this application is connected to the vehicle door and the other end is connected to the second engaging member, and a telescopic section is formed on the second engaging member, the rotation of the first engaging member can stretch the telescopic end.

[0020] Since the first engaging member is engaged with the second engaging member and the first detecting member is connected to the second engaging member in the present application, the rotation of the first engaging member can drive the second engaging member to rotate, thereby rotating the first detecting member, so that the detecting surface of the first detecting member is always facing the rear of the vehicle, thereby being able to monitor the vehicles coming from behind at all times, and to reduce the probability of accidents caused by opening the door and colliding with vehicles coming from behind to a certain extent.

[0021] In addition, the present invention also provides a vehicle including the above-mentioned door opening anti-collision monitoring system. A vehicle using the door opening anti-collision monitoring system provided by this application can monitor vehicles coming from behind at all times while the driver and passengers are opening the vehicle doors. Once a vehicle coming from behind is detected, it can respond in a timely manner, thereby reducing the problem of collision with vehicles coming from behind due to improper door opening, which may cause personal injury, and thus can improve the safety performance of the vehicle to a certain extent.

[0038] like Figure 1 Combine Figure 2 As shown, the present invention provides a door-opening anti-collision monitoring system for a vehicle, including a monitoring mechanism, which includes a traction assembly, an engagement assembly and a first detection member 5; the traction assembly includes a first traction member 1 and a second traction member 2, and the engagement assembly includes a first engagement member 3 and a second engagement member 4; one end of the first traction member 1 is connected to a support column 14 of the vehicle, and the other end is connected to a first position 301 of the first engagement member 3, one end of the second traction member 2 is connected to a door of the vehicle, and the other end is connected to a second position 302 of the first engagement member 3, and a telescopic section 202 is formed on the second traction member 2 to enable the second traction member 2 to be extended or shortened; the first engagement member 3 and the second engagement member 4 are engaged with each other, and the first detection member 5 is connected to the second engagement member 4, and the rotation of the first engagement member 3 can drive the rotation of the second engagement member 4, so that the detection surface of the first detection member 5 is always facing the rear of the vehicle.

[0039] Compared with the existing technology, the door opening anti-collision monitoring system provided by the present invention has the following advantages:

[0040] The door opening anti-collision monitoring system provided by the present invention connects one end of the first traction member 1 to the support column 14 and the other end to the first position 301 of the first engaging member 3, and the first engaging member 3 is rotationally connected to the vehicle door, so that when the vehicle door is opened, the first engaging member 3 can be pulled to rotate by the first traction member 1. Since one end of the second traction member 2 in this application is connected to the vehicle door and the other end is connected to the second engaging member 4, and a telescopic section 202 is formed on the second engaging member 4, the rotation of the first engaging member 3 can stretch the telescopic end.

[0041] Since the first engaging member 3 is engaged with the second engaging member 4 and the first detecting member 5 is connected to the second engaging member 4 in the present application, the rotation of the first engaging member 3 can drive the second engaging member 4 to rotate, thereby rotating the first detecting member 5, so that the detecting surface of the first detecting member 5 is always facing the rear of the vehicle, thereby being able to monitor the vehicles coming from behind at all times, and to reduce the probability of accidents caused by opening the door and colliding with vehicles coming from behind to a certain extent.

[0042] The monitoring mechanism provided in this application can be optionally installed according to specific configuration requirements. Taking the highest configuration as an example, when the vehicle has four doors, the two doors corresponding to the main driver and co-driver positions and the two doors corresponding to the rear passengers are equipped with monitoring mechanisms, so that when any door is opened, vehicles coming from behind can be monitored, thereby improving the safety factor of the entire vehicle.

[0043] It can be understood that the support column 14 in this application refers to the A-pillar and B-pillar of the vehicle. When only the doors corresponding to the main driver and the co-driver are equipped with monitoring mechanisms, one end of the first traction member 1 is connected to the A-pillar of the vehicle. When only the doors corresponding to the rear passenger position are equipped with monitoring mechanisms, one end of the first traction member 1 is connected to the B-pillar of the vehicle. When all doors are equipped with monitoring mechanisms, the first traction member 1 is connected to the corresponding A-pillar and B-pillar.

[0044] It should be noted that the first meshing member 3 in the present application can be a crown gear, and the second meshing member 4 can be a cylindrical gear. The first meshing member 3 and the second meshing member 4 can also both be bevel gears to achieve meshing and transmission.

[0045] It is necessary to further explain here that Figure 1Taking the perspective shown in as an example, when the car door is in a closed state, the first traction member 1 can be wrapped around the central axis of the first engaging member 3, and the telescopic end is in a naturally contracted state. When the car door is opened, the first traction member 1 pulls the first engaging member 3 to rotate clockwise, thereby gradually stretching the telescopic end. The rotation of the first engaging member 3 can drive the second engaging member 4 to rotate counterclockwise, thereby causing the first detection member 5 to rotate counterclockwise, and then causing the detection surface of the first detection member 5 to rotate in the direction close to the vehicle body, thereby achieving the purpose of always having the detection surface facing the rear of the vehicle for monitoring.

[0046] When the car door is closed from an open state, the telescopic end contracts and drives the first engaging member 3 to rotate counterclockwise. On the one hand, the first traction member 1 is wrapped around the rotating shaft of the first engaging member 3 again. On the other hand, it can drive the second engaging member 4 to rotate clockwise, thereby causing the first detection member 5 to rotate clockwise and return to its initial position, avoiding the first detection member 5 from affecting the closing of the car door, and also avoiding the problem of damage to the first detection member 5 caused by closing the car door.

[0047] Alternatively, as Figure 4 As shown, the door opening anti-collision monitoring system provided by the present invention further includes a second detection component 6, and the second detection component 6 is arranged at the rear fender of the vehicle.

[0048] Preferably, the number of the second detection members 6 in the present application is two, and they are arranged on both sides of the vehicle and located inside the rear fender. Optionally, the rear fender can be opened at a corresponding position of the second detection member 6 to avoid the rear fender affecting the monitoring of the second detection member 6.

[0049] When the vehicle coming from behind is at a high speed and has reached a position near the rear fender of the vehicle, a collision with the vehicle will occur the moment the door is opened. Therefore, the present application provides a second detection member 6 at the position of the rear fender to timely monitor the vehicle approaching the rear of the vehicle at a high speed, thereby further avoiding collisions caused by opening the door and improving the safety factor of the vehicle.

[0050] It should be noted here that, preferably, the first detection member 5 and the second detection member 6 in the present application are both radars, and further preferably, the monitoring range of the second detection member 6 in the present application is based on the center of the second detection member 6, and has a 60° monitoring coverage range toward the rear and front of the vehicle, thereby obtaining a 120° monitoring coverage range.

[0051] Optionally, in order to ensure that the monitoring mechanism can respond in time when it detects a vehicle coming from behind, the door opening anti-collision monitoring system provided by the present invention also includes a door locking device, which includes a locking mechanism and a driving mechanism 7. The driving mechanism 7 is communicatively connected to the first detection member 5 and the second detection member 6. The first detection member 5 and the second detection member 6 can send a signal to control the driving mechanism 7 to start, so as to start the locking mechanism to lock the door.

[0052] When parking, when the second detection member 6 detects a vehicle coming from behind, the drive mechanism 7 is controlled to start, thereby starting the locking mechanism to lock the door. When the second detection member 6 does not detect a vehicle coming from behind, the drive mechanism 7 is not started, and the door can be opened normally. When opening, once the first detection member 5 detects a vehicle coming from behind, the drive mechanism 7 is controlled to start, thereby starting the locking mechanism to lock the door.

[0053] This application provides one implementation method for locking a vehicle door, such as Figure 3 As shown, the locking mechanism in the present application includes a limit member 9, a transmission member 10 and a locking member 8; the driving mechanism 7 is connected to the locking member 8 to drive the locking member 8 to move toward or away from the transmission member 10, and the transmission member 10 cooperates with the limit member 9. One end of the limit member 9 is rotatably connected to the support column 14 corresponding to the vehicle, and the other end is rotatably connected to the vehicle door, and the driving mechanism 7, the locking member 8 and the transmission member 10 are all arranged inside the vehicle door.

[0054] When the second detection member 6 or the first detection member 5 detects a vehicle coming from behind, a signal is sent to the vehicle controller, which controls the driving mechanism 7 to start, thereby driving the locking member 8 to move in the direction close to the transmission member 10 until it contacts the transmission member 10, thereby stopping the transmission member 10 through the locking member 8. Since the transmission member 10 cooperates with the limiting member 9, and one end of the limiting member 9 is connected to the corresponding support column 14 and the other end is connected to the vehicle door, when the transmission member 10 stops rotating, the position of the vehicle door can no longer change, thereby achieving the locking of the vehicle door.

[0055] When both the second detection member 6 and the first detection member 5 detect a vehicle coming from behind, the drive mechanism 7 will not start, so that the locking member 8 is in a state of separation from the transmission member 10. When the door moves, the transmission member 10 can rotate along the extension direction of the limit member 9, thereby realizing the opening and closing of the door.

[0056] Preferably, if Figure 3 As shown, the limiting member 9 in the present application is a rack, the transmission member 10 is a gear, and a tooth portion 801 is formed on the side of the locking member 8 facing the transmission member 10 , and the tooth portion 801 is parallel to the limiting member 9 .

[0057] By meshing the tooth portion 801 with the gear, and the gear with the rack, the door position can be locked, reducing the problem of collision with the rear vehicle when the door is opened.

[0058] It should be noted here that the connection position of the limit member 9 and the support column 14 in this application is the first connection point 901, and the connection position with the vehicle door is the second connection point 902, and the two ends of the limit member 9 in this application are respectively rotatably connected to the vehicle door and the support column 14, so that the vehicle door can be opened and closed smoothly.

[0059] More preferably, Figure 3 As shown, there are two transmission members 10 in the present application, which are relatively arranged on both sides of the limiting member 9, the locking member 8 and the transmission member 10 are arranged in a one-to-one correspondence, and the driving mechanism 7 and the locking member 8 are arranged in a one-to-one correspondence.

[0060] The driving mechanism 7 in the present application is a driving motor, and it can be understood that in order to realize the movement of the locking member 8 in the direction close to or away from the transmission member 10, a reversing gear and a screw rod can be used, that is, the output shaft of the driving motor is provided with a first gear coaxial with the output shaft, and a second gear meshing with the first gear is provided to realize reversing, the second gear is connected to the screw rod, and a slider is provided on the screw rod. When the screw rod rotates, the slider can reciprocate along the screw rod, and the function of moving the tooth portion 801 in the direction close to or away from the transmission member 10 is realized by connecting the slider to the tooth portion 801.

[0061] By providing two transmission members 10 and making the locking member 8 correspond to the transmission member 10 one-to-one, and the driving mechanism 7 correspond to the locking member 8 one-to-one, the force during locking and door opening and closing can be made more uniform, making the opening, closing and locking of the door smoother and more timely.

[0062] Alternatively, as Figure 1 As shown, the telescopic section 202 in the present application is a spring, and the second traction member 2 includes a first connecting section 201 and a second connecting section 203. One end of the first connecting section 201 is connected to the vehicle door, and the other end is connected to one end of the spring. The other end of the spring is connected to one end of the second connecting section 203, and the other end of the second connecting section 203 is connected to the second position 302 of the first engaging member 3.

[0063] Preferably, if Figure 1 As shown, in the present application, the first connecting section 201 and the second connecting section 203 are both metal rods, so that the spring can be stably compressed and positioned. Accordingly, the first traction member 1 is a steel wire, so that it can be wound around the rotating shaft of the first engaging member 3 for retraction and extension.

[0064] More preferably, Figure 1As shown, in order to improve the degree of automation of the vehicle door opening and closing process, in this application, a contact piece 2021 is provided at the connecting end of the spring and the second connecting section 203, and a sensing piece 13 is provided in the vehicle door. The contact piece 2021 is communicatively connected with the first detection piece 5. When the contact piece 2021 contacts the sensing piece 13, the contact piece 2021 controls the first detection piece 5 to stop detection.

[0065] When the car door is opened, the spring is stretched, causing the contact piece 2021 at the end of the spring to move toward the direction close to the sensing piece 13. When the contact piece 2021 contacts the sensing piece 13, the first detection piece 5 is controlled to stop detecting. Since the first detection piece 5 stops detecting, the driving mechanism 7 will not start.

[0066] It can be understood that in this application, the sensing element 13 can be located at the position where the contact element 2021 moves when the car door is opened to an angle that allows people to get off the car, or it can be located at the position where the contact element 2021 moves when the car door is opened to the maximum angle.

[0067] When the contact member 2021 contacts the sensing member 13, the driving mechanism 7 will not start, the locking mechanism is in a disabled state, and the vehicle door will not be locked, so that the vehicle door can be closed smoothly.

[0068] It should be noted here that since a door limiter is provided between the door and the support column 14 of the vehicle body, the above-mentioned locking device in this application can exist at the same time as the door limiter, and the door limiter can also be improved to have the function of a locking device.

[0069] like Figure 5 As shown, the present application provides another embodiment, which improves the vehicle door limiter, arranges an elastic member 12 and a locking member 8 in the limit box 11, and connects the driving mechanism 7 to the elastic member 12. The elastic member 12 can be driven by the driving mechanism 7, so that the elastic member 12 can drive the locking member 8 to move toward or away from the limit member 9.

[0070] Furthermore, meshing teeth are added to the outer wall of the limit member 9. When the locking member 8 approaches the limit member 9 and meshes with the meshing teeth, the vehicle door can be locked. When the locking member 8 moves away from the limit member 9, the tooth portion 801 can be separated from the meshing teeth, so that the vehicle door can be opened or closed smoothly.

[0071] In addition, the present invention also provides a vehicle including the above-mentioned door opening anti-collision monitoring system. A vehicle using the door opening anti-collision monitoring system provided by this application can monitor vehicles coming from behind at all times while the driver and passengers are opening the vehicle doors. Once a vehicle coming from behind is detected, it can respond in a timely manner, thereby reducing the problem of collision with vehicles coming from behind due to improper door opening, which may cause personal injury, and thus can improve the safety performance of the vehicle to a certain extent.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
