Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if the meaning of "and / or" appearing in the full text is to include three parallel schemes, taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0031] In a first aspect, the present application provides a vehicle seat belt status reminder system 100. Figure 1 It is a structural block diagram of an embodiment of the vehicle seat belt status reminder system 100 provided in the present application.

[0032] Combination Figure 1 The vehicle seat belt status reminder device includes a detection device 10, a control device 20, an alarm device 30 and a seat belt assembly 40. Each device can be set independently of the original device of the vehicle, or part of the original device of the vehicle can be used as part of the above device, which is not specifically limited here.

[0033] Specifically, the detection device 10 is used to detect whether a seat of the vehicle is occupied. The detection device 10 can be various types of detection devices in the prior art to detect whether a seat is occupied by a person through its existing detection function. The seats to be detected can be all seats of the vehicle or part of the seats of the vehicle, such as seats other than the main driver's seat of the vehicle, which is not specifically limited here.

[0034] The control device 20 is connected to the detection device 10, and the detection device 10 is used to send a first signal to the control device 20 when someone is sitting on the seat. At this time, the control device 20 can be an original controller of the vehicle, or a controller independently set up from the original controller of the vehicle. The control device 20 and the detection device 10 can be connected in a wired or wireless manner, so that the first signal sent by the detection device 10 can be transmitted to the control device 20. Among them, the first signal can be an electrical signal.

[0035] The alarm device 30 is connected to the control device 20. Similarly, the alarm device 30 and the control device 20 can be connected by wire or wireless. The control device 20 is used to send a second signal to the alarm device 30 when receiving the first signal, and the alarm device 30 is used to send an alarm signal when receiving the second signal. The second signal can be an electrical signal or a non-electrical signal, which is not specifically limited here. It should be understood that at this time, as long as there is someone on the seat, the control device 20 will send a signal to the alarm device 30, and then the alarm device 30 will generate an alarm signal to display the alarm signal to the user.

[0036] Furthermore, the seat belt assembly 40 is provided with a lock buckle 41, a lock tongue 42 and a shielding device 43. At this time, a lock tongue 42 may be provided at one end of the belt of the seat belt, and when the lock tongue 42 is inserted into the lock buckle 41, the seat belt is in a fastened state. When the lock tongue 42 is inserted into the lock buckle 41, that is, when the seat belt is in a fastened state, the shielding device 43 will work to shield the second signal, so that the alarm device 30 stops sending an alarm signal.

[0037] It should be understood that when the seat belt is not fastened, the control device 20 will continue to send the second signal to the alarm device 30, so that the alarm device 30 will continue to generate an alarm signal, so that the alarm device 30 will continue to alarm, and the alarm type at this time is an alarm of the seat belt not being fastened. When the seat belt is fastened, the shielding device 43 shields the second signal, which will cause the control device 20 to interrupt the second signal sent to the alarm device 30, so that the alarm device 30 interrupts the generation of the alarm signal, and then the alarm device 30 stops the alarm.

[0038] In summary, by setting the shielding device 43, when the seat belt on the seat is not fastened, the alarm device 30 will keep alarming to remind the user that the seat belt is not fastened. After the seat belt is fastened, the alarm device 30 stops working due to the operation of the shielding device 43, and then stops the alarm. Therefore, the core component is only provided with the shielding device 43 to achieve a good alarm effect, and the structure is simple.

[0039] Figure 2 It is a structural block diagram of another embodiment of the vehicle seat belt status reminder system 100 provided in the present application.

[0040] Combination Figure 2 In some specific embodiments, the shielding device 43 is provided with a power supply circuit 431, and the power supply circuit 431 is used to supply power to the shielding device 43. The power supply circuit 431 can be connected to an external power supply, so that the external power supply can supply power to the power supply circuit 431, and then the shielding device 43 is supplied with power through the power supply circuit 431 so that the shielding device 43 works normally.

[0041] At this time, when the lock tongue 42 is not inserted into the lock buckle 41, the power supply circuit 431 is not turned on, and the power supply circuit 431 does not supply power to the shielding device 43, so that the shielding device 43 does not work. When the lock tongue 42 is inserted into the lock buckle 41, the power supply circuit 431 is turned on, and the power supply circuit 431 supplies power to the shielding device 43, so that the shielding device 43 works.

[0042] Therefore, in this embodiment, the combination state between the lock tongue 42 and the lock buckle 41 determines whether the power supply circuit 431 is turned on or off, that is, determines whether the shielding device 43 is powered and determines whether the shielding device 43 is working.

[0043] Of course, in other embodiments, the working mode of the shielding device 43 is not limited to this. For example, the shielding device 43 can be in a power supply state all the time, but before the lock tongue 42 is combined with the lock buckle 41, the shielding device 43 cannot shield the signal. After the lock tongue 42 is combined with the lock buckle 41, the shielding device 43 will work to shield the signal.

[0044] Continue to combine Figure 2 In some specific embodiments, corresponding to the embodiment in which the power supply circuit 431 is provided, the shielding device 43 is further provided with a main body module 432, and the power supply circuit 431 is connected to the main body module 432. The main body module 432 is provided on the lock buckle 41 or the lock tongue 42, and the power supply circuit 431 is provided on the lock buckle 41. When the lock tongue 42 is inserted into the lock buckle 41, the power supply circuit 431 is turned on to supply power to the main body module 432 so that the main body module 432 works to shield the second signal.

[0045] Specifically, the main body module 432 constitutes the functional body of the shielding device 43. When the power supply circuit 431 supplies power to the main body module 432, the main body module 432 works to perform the shielding function. The main body module 432 can be set on either the lock buckle 41 or the lock tongue 42, and can be set according to the specific situation, and no specific restrictions are made here. For example, in some application scenarios, in order to ensure the simplicity of the structure of the lock tongue 42 and realize the hidden setting of the main body module 432, the main body module 432 can be set on the lock buckle 41. Combined with the working mode of the above-mentioned power supply circuit 431, whether the lock tongue 42 is combined with the lock buckle 41 at this time determines the on-off of the power supply circuit 431.

[0046] More specifically, the main module 432 can send specific working signals when working, and these working signals can shield the second signal. The shielding device 43 is configured to only shield the second signal, and other signals other than the second signal, such as the first signal, cannot be shielded, thereby ensuring the normal transmission of other signals on the vehicle.

[0047] Figure 3It is a structural block diagram of another embodiment of the vehicle seat belt status reminder system 100 provided in the present application.

[0048] Combination Figure 3 In some specific embodiments, the vehicle seat belt status reminder system 100 further includes a pressure detection device 50, which is connected to the detection device 10. The pressure detection device 50 is used to detect the pressure on the seat. The pressure detection device 50 can be used to detect the pressure of the seat cushion, and further determine whether there is a person or heavy object on the seat. The pressure detection device 50 can include multiple parts, and the multiple parts can be respectively set on different seats of the vehicle, so as to realize pressure detection on different seats.

[0049] Specifically, when the pressure detection device 50 detects that the pressure on the seat is greater than the threshold pressure, the pressure detection device 50 sends a third signal to the detection device 10. The threshold pressure is preset and can be a relatively large pressure value. When the pressure detection device 50 detects that the pressure on the seat is greater than the threshold pressure, it means that there is a heavy object on the seat, and it is likely to be a person, and only then will the third signal be sent to the detection device 10, and only then will further detection of whether there is someone sitting on the seat be performed in the subsequent process. It should be understood that the third signal will not be shielded by the shielding device 43.

[0050] When the detection device 10 receives the third signal, the detection device 10 detects whether the seat is occupied to determine whether the person on the seat is a human. At this time, the detection device 10 can be a thermal imaging detection device 10 to facilitate the detection of people and objects and obtain human body shape information.

[0051] In this embodiment, the pressure detection device 50 first performs detection, and only when the pressure detection device 50 detects a heavy object will further detection be performed, thereby avoiding waste of resources caused by the detection device 10 working all the time.

[0052] Figure 4 It is a structural block diagram of another embodiment of the vehicle seat belt status reminder system 100 provided in the present application.

[0053] Combination Figure 4In some specific embodiments, the detection device 10 includes a first detection device 11 and a second detection device 12, wherein the first detection device 11 is disposed on the front passenger seat of the vehicle, and the second detection device 12 is disposed on the rear seat of the vehicle. The first detection device 11 and the second detection device 12 are both part of the detection device 10, and the settings of the first detection device 11 and the second detection device 12 can be the same or similar, so that the first detection device 11 and the second detection device 12 can both achieve the same or similar detection effects. At this time, the first detection device 11 is used to detect whether the heavy object on the front passenger seat is a human, and the second detection device 12 is used to detect whether the heavy object on the rear seat is a human.

[0054] Furthermore, in addition to detecting whether the person is a human, the first detection device 11 is also used to detect whether the occupant on the seat is a child, and sends a fourth signal to the alarm device 30 when it is detected that the occupant is a child, so that the alarm device 30 sends an alarm signal when receiving the fourth signal.

[0055] It should be understood that the first detection device 11 can detect the obtained body shape information, and further obtain the pressure information obtained by the pressure detection device 50 to detect whether the occupant on the seat is a child. In vehicle regulations, children are not allowed to sit on the front passenger seat, so when a child is sitting on the front passenger seat, the driver will be reminded. At this time, the detection device 10 will directly send the fourth signal to the alarm device 30, and will not send the second signal to the alarm device 30 through the control device 20, so that the alarm device 30 directly sends an alarm signal according to the fourth signal to alarm.

[0056] Among them, since the shielding device 43 can only shield the second signal, the shielding device 43 cannot shield the fourth signal regardless of whether the seat belt is fastened. Therefore, regardless of whether the seat belt is fastened, the alarm device 30 will always be in a state of sending an alarm signal, thereby providing a good reminder to the driver until the child leaves the passenger seat.

[0057] Figure 5 It is a structural block diagram of another embodiment of the vehicle seat belt status reminder system 100 provided in the present application.

[0058] Combination Figure 5 In some specific embodiments, the seat belt assembly 40 is further provided with a communication module 60, and the communication module 60 is connected to the main controller of the vehicle and the control device 20. The communication module 60 and the main controller of the vehicle and the control device 20 can be connected by wire or wirelessly, which is not specifically limited here.

[0059] The user can set the safety status reminder mode on the vehicle screen, so that the main controller can turn on the safety status reminder mode. When the main controller turns on the safety status reminder mode, the main controller sends a working signal to the control device 20 through the communication module 60, so that the control device 20 sends a second signal based on the working signal. Therefore, in this embodiment, only when the user turns on the safety status reminder mode, the control device 20 can send the second signal, and then the alarm device 30 can send an alarm signal.

[0060] Figure 6 It is a structural block diagram of another embodiment of the vehicle seat belt status reminder system 100 provided in the present application.

[0061] Combination Figure 6 In some specific embodiments, the alarm device 30 includes a sound alarm device 31 and an image alarm device 32. The image alarm device 32 is used to send an alarm signal of an alarm image type, and the sound alarm device 31 is used to send an alarm signal of an alarm sound type.

[0062] Specifically, two alarm modes are provided in this embodiment. In specific applications, one alarm mode can be selected for application according to actual conditions, or both alarm modes can be used at the same time, and no specific limitation is made here.

[0063] A second aspect of the present application provides a vehicle seat belt status reminder method, which is based on the vehicle seat belt status reminder system 100 in any of the above embodiments.

[0064] Figure 7 This is a flow chart of an embodiment of the vehicle seat belt status reminder method provided by the present application, combined with Figure 7 , the method comprises the following steps:

[0065] S101: Detect whether there is anyone sitting on the seat of the vehicle.

[0066] In combination with the above embodiments, the detection device can be used to detect whether there is a person on the seat. Moreover, the pressure detection device can be used to detect whether there is a heavy object on the seat before the detection, which is not specifically limited here.

[0067] S102: When it is detected that someone is sitting on the seat, a first signal is sent to the control device so that the control device sends a second signal to the alarm device, so that the alarm device sends an alarm signal based on the second signal.

[0068] When it is detected that someone is sitting on the seat, the detection device can be controlled to send a first signal. When the control device receives the first signal, it further sends a second signal to the alarm device, so that the alarm device sends an alarm signal based on the second signal.

[0069] Figure 8 FIG. 1 is a flow chart of another embodiment of the vehicle seat belt status reminder method provided by the present application. Figure 8 In some specific embodiments, after the step of detecting whether there is someone sitting on the seat of the vehicle, that is, after the above step S101, it also includes:

[0070] S201: When it is detected that someone is sitting in the seat and the seat is a rear seat, the step of sending a first signal to the control device so that the control device sends a second signal to the alarm device so that the alarm device sends an alarm signal based on the second signal is executed.

[0071] When it is detected that someone is sitting in the seat, if the seat is a back seat, then there is no situation where a child cannot sit on it, so the step of sending the first signal is directly executed at this time, and the subsequent steps are performed according to the above embodiment.

[0072] S202: When it is detected that someone is sitting in the seat and the seat is a front passenger seat, it is detected whether the occupant in the seat is a child, and when it is detected that the occupant in the seat is a child, a fourth signal is sent to the alarm device, so that the alarm device sends an alarm signal based on the fourth signal.

[0073] When the seat is detected as a passenger seat, it means that a child may be sitting on it, which is not allowed by law. Therefore, at this time, it will further detect whether the seat is occupied by a child.

[0074] When it is detected that the passenger is a child, which is not allowed by law, the detection device will be directly controlled to send a fourth signal to the alarm device, so that the alarm device directly sends an alarm signal based on the fourth signal. Therefore, the control method provided by this embodiment can effectively avoid the situation where the passenger sits on the front passenger seat.

[0075] The third aspect of the present application provides a vehicle, comprising the vehicle seat belt status reminder system in any of the above embodiments. For the specific description of the vehicle seat belt status reminder system, please refer to the content of the above embodiments, and no further description will be given.

[0076] In summary, the vehicle seat belt status reminder system, method and vehicle provided by the present application include: a detection device for detecting whether there is someone sitting on the seat of the vehicle; a control device connected to the detection device, the detection device is used to send a first signal to the control device when there is someone sitting on the seat; an alarm device is connected to the control device, the control device is used to send a second signal to the alarm device when receiving the first signal, and the alarm device is used to send an alarm signal when receiving the second signal; a seat belt assembly is provided with a lock, a lock tongue and a shielding device, when the lock tongue is inserted into the lock, the shielding device works to shield the second signal, so that the alarm device stops sending an alarm signal.
