The position of the stopper 135 at the screw 132 is adjustable so as to limit the maximum distance that the guide block 133 moves up and down.

As shown in fig. 8, the method includes: step S1: when at least one of the adjusting button 14, the voice receiver 16 and the image collector 17 receives the adjusting signal, the processor 18 controls the adjusting mechanism 13 to drive the guide ring 12 to move according to the adjusting signal. The adjusting signal includes a physical adjusting signal, a voice adjusting signal, and an image adjusting signal, the adjusting button 14 is used to receive the physical adjusting signal, for example, the user presses the adjusting button 14, the voice receiver 16 is used to receive the voice adjusting signal, for example, the user says "up", "down", or "down", and the image collector 17 is used to receive the image adjusting signal, for example, an image of the user's finger pointing up or an image of the user's finger pointing down, which is not limited to this.

Specifically, when the user presses the adjustment button 14, that is, the adjustment button 14 receives the physical adjustment signal, the processor 18 controls the adjustment mechanism 13 to drive the guide ring 12 to move according to the physical adjustment signal. The adjusting button 14 comprises an up-adjusting button and a down-adjusting button, when a user presses the up-adjusting button, the processor 18 controls the adjusting mechanism 13 to drive the guide ring 12 to move upwards, so that the safety belt 11 is adjusted to be high; when the user presses the down button, the processor 18 controls the adjustment mechanism 13 to drive the guide ring 12 downwards, thereby lowering the seat belt 11.

When the user speaks an instruction of up-regulation, namely the voice receiver 16 receives a voice regulation signal of up-regulation, the processor 18 controls the regulating mechanism 13 to drive the guide ring 12 to move upwards, so that the safety belt 11 is adjusted upwards; when the user speaks a down command, i.e. the voice receiver 16 receives a down voice adjustment signal, the processor 18 controls the adjustment mechanism 13 to drive the guide ring 12 to move downwards, thereby lowering the seat belt 11.

When the user performs an up-regulation action, namely the image collector 17 receives an up-regulated image regulation signal, the processor 18 controls the regulating mechanism 13 to drive the guide ring 12 to move upwards, so that the safety belt 11 is heightened; when the user performs the down-regulation action, i.e. the image collector 17 receives the down-regulated image regulation signal, the processor 18 controls the regulating mechanism 13 to drive the guide ring 12 to move downwards, so that the safety belt 11 is adjusted downwards. Of course, when the adjustment button 14, the voice receiver 16, and the image acquirer 17 receive a plurality of adjustment signals, one adjustment signal to be processed preferentially may be set. For example, a physical adjustment signal is preferred, a voice adjustment signal is followed, and a picture adjustment signal is followed, and when the preferred adjustment signal occurs, the other signals are disabled. When the adjustment button 14, the voice receiver 16 and the image collector 17 simultaneously receive the adjustment signal, the processor 18 controls the adjustment mechanism 13 to drive the guide ring 12 to move according to the physical adjustment signal received by the adjustment button 14, and the voice adjustment signal and the image adjustment signal are invalid signals, which is not limited to this.

Step S2: the memory signal is inputted through at least one of the memory button 15, the voice receiver 16 and the image collector 17, and the processor 18 records the position of the guide ring 12 and the trigger signal corresponding to the position according to the memory signal. The memory signal includes a physical memory signal, a voice memory signal and an image memory signal, the memory button 15 is used for inputting the physical memory signal, for example, a user presses the memory button 15, the voice receiver 16 is used for inputting the voice memory signal, for example, the user speaks "record" or "memory", and the image collector 17 is used for inputting the image memory signal, for example, an image of a finger of the user pointing to the right, which is not limited to this.

Specifically, at least one of the memory button 15, the voice receiver 16 and the image collector 17 inputs a memory signal, and the processor 18 records the position of the guide ring 12 and a trigger signal corresponding to the position according to the memory signal. The trigger signal may be preset, or the trigger signal may be input after the memory signal is input. The trigger signals include a physical trigger signal, a voice trigger signal and an image trigger signal, the memory button 15 is used for inputting the physical trigger signal, the physical trigger signal and the physical memory signal need to be distinguished, for example, the user presses (long press, short press or twice continuous press) the memory button 15, the voice receiver 16 is used for inputting the voice trigger signal, for example, the user says "automatic adjustment", the image collector 17 is used for inputting the image trigger signal, for example, an image of the finger of the user pointing to the left, preferably, the image trigger signal can be the long phase of the user, the height or the body shape of the user, and the invention is not limited thereto.

Step S3: when at least one of the memory button 15, the voice receiver 16 and the image collector 17 receives the trigger signal, the processor 18 controls the adjusting mechanism 13 to drive the guide ring 12 to move to a position corresponding to the trigger signal according to the trigger signal. The processor 18 compares the trigger signals received by the memory button 15, the voice receiver 16 and the image collector 17 with the stored trigger signals, if the received trigger signals are successfully compared with the stored trigger signals, the processor 18 directly controls the control adjusting mechanism 13 to drive the guide ring 12 to move to the position corresponding to the stored trigger signals, so that the safety belt 11 is automatically adjusted to the corresponding height, the situation that different users manually adjust the height of the safety belt 11 every time is avoided, the operation trouble is reduced, and the user experience is improved.

Preferably, when at least one of the adjusting button 14, the voice receiver 16 and the image collector 17 inputs a memory signal, the processor 18 records an image trigger signal through the image collector 17, that is, records the user's long phase, and when the user uses the device next time, the image collector 17 transmits the collected image to the processor 18 and compares the collected image with the stored image.

When the adjustment button 14, the voice receiver 16, and the image acquirer 17 receive a plurality of trigger signals, a trigger signal to be processed preferentially can be set. For example, a voice trigger signal is preferred, a physical trigger signal is preferred, and an image trigger signal is preferred, and when a preferred adjustment signal occurs, the other signals are disabled. For example, when the adjustment button 14, the voice receiver 16, and the image collector 17 simultaneously receive the trigger signal, the processor 18 controls the adjustment mechanism 13 to drive the guide ring 12 to move to the position corresponding to the voice trigger signal according to the voice trigger signal received by the voice receiver 16, which is not limited to this.

The method further comprises the following steps: when the vehicle speed is greater than 20 ㎞/h, the processor 18 does not control the adjusting mechanism 13 to drive the guide ring 12 to move according to the adjusting signal or the triggering signal, namely when the vehicle speed is detected to be greater than 20 ㎞/h, the user cannot adjust the height of the safety belt 11 through the adjusting signal or the triggering signal, and the safety accident caused by misoperation in the driving process is avoided.

The invention also provides an automobile which is controlled by applying the safety belt height adjusting method.
