DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are 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.

[0029] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as those commonly understood by technicians in the technical field of this application; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned drawings and any variations thereof are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary and secondary relationship.

[0030] This application is based on the inventor's discovery and understanding of the following facts and problems:

[0031] Dangerous driving behavior is a taboo for drivers. With the increase of driving time or continuous high-speed driving, drivers will experience driving fatigue to varying degrees. During driving, turning the head, squinting to observe the road conditions ahead, or bending down quickly to pick up items will inevitably lead to distracted driving.

[0032] In the field of assisted driving, the DMS driver monitoring system plays an important role in reminding drivers of dangerous driving phenomena. DMS senses the facial features of the driver through the camera, and determines the driver's dangerous driving actions based on the facial features, and finally controls the on-board speakers to give timely voice reminders to the driver. However, while the camera collects the driver's facial features, it will inevitably capture the interior space of the car within the wide-angle field of view, leaking the privacy of the car. In view of the needs of drivers and passengers in the car for privacy protection, a DMS camera shielding device that can achieve adaptive shielding is needed for the time when the driver is not driving.

[0033] In order to solve the above problems, the present application embodiment provides a DMS camera shielding device. Figure 1-Figure 9 The DMS camera shielding device of the embodiment of the present application is described in detail.

[0034] like Figure 1 As shown, the embodiment of the present application provides a DMS camera shielding device, which includes a housing assembly, a transmission member, a driving member and a baffle 3. The housing assembly includes a support seat 1, please refer to Figure 4 The first side of the support seat 1 is connected to the slide seat 2 and is recessed inward to form a first chamber 11 to accommodate the camera. It can be understood that the first chamber 11 extends to the opening side of the support seat 1, and the camera can be facing this side to monitor the driver's driving behavior. In the embodiment of the present application, in order to block the camera, the baffle 3 needs to be set on the opening side of the first chamber 11 to enclose the camera inside the first chamber 11.

[0035] For details, please refer to Figure 3 and Figure 7 The slide seat 2 includes a notch 21 and a second chamber 22 adjacent to the notch 21. A slider 23 is slidably connected inside the notch 21. A groove is provided between the second chamber 22 and the notch 21 to communicate with each other. The transmission member is provided in the second chamber 22 and extends along the first direction X1. At least part of the transmission member extends out of the groove along the second direction X2 to abut against and engage with the slider 23. The driving member is provided in the first chamber 11 and at least partly extends into the second chamber 22 to connect with the transmission member. The baffle 3 is provided outside the first chamber 11 and is limitedly connected to the slider 23. The baffle 3 is slidably connected to the slide seat 2.

[0036] It can be understood that the side of the baffle 3 is connected to the slider 23, and the slider 23 is disposed in the slot 21 of the slide seat 2 and can slide along the first direction X1 inside the slot 21. In addition, in order to apply a driving external force along the first direction X1 to the slider 23, a groove is provided between the second chamber 22 and the slot 21 to ensure that the two are connected, so that part of the structure of the transmission member can extend from the second chamber 22 to the slot 21 to drive the slider 23 to move.

[0037] In some embodiments, please refer to Figure 3 A light shield 4 is provided on the outside of the camera, the baffle 3 is located on the side of the light shield 4 away from the support seat 1, the bottom of the baffle 3 is connected to a limiter 31, the slot 21 is formed by being recessed inward from one side of the slide slot seat 2, and the projection of the limiter 31 along the first direction X1 at least partially overlaps with the inner wall of the slot 21.

[0038] It is understandable that by setting the sunshade 4, stray light can be suppressed from entering the camera, thereby eliminating fog and improving the clarity and color reproduction of the image, and the baffle 3 can block the light entering the sunshade 4, thereby preventing the camera from capturing information inside the vehicle. During the movement of the baffle 3, on the one hand, the algorithm can be set to prevent the baffle from escaping from the range of the slot 21 along the first direction X1, and on the other hand, since the projection of the stopper 31 along the first direction X1 at least partially overlaps with the inner wall of the slot 21, the action of the stopper 31 can also prevent the baffle from escaping from the slot 21.

[0039] In some embodiments, please refer to Figure 1 There are two slide groove seats 2 and they are symmetrically arranged at the two opposite ends of the support seat 1 along the second direction X2. The slide groove seats 2, the driving members and the transmission members correspond one to one. The two driving members and the two transmission members are symmetrically arranged about the central axis of the support seat.

[0040] It can be understood that the two slide groove seats 2 are symmetrically arranged at both ends of the support seat 1. The two slide groove seats 2 can jointly provide a limiting effect on the baffle 3. Both sides of the baffle 3 can be driven by two transmission parts at the same time, thereby ensuring that the baffle 3 can be smoothly adjusted in position along the first direction X1.

[0041] In some embodiments, please refer to Figure 4 , Figure 7 , Figure 8 and Fig. 9 The driving member includes a motor 5, the output shaft of the motor 5 is limitedly connected to a transmission shaft 51, the support seat 1 and the slide seat 2 are provided with a through hole A to connect the first chamber 11 and the second chamber 22, the transmission shaft 51 passes through the through hole A into the second chamber 22 and is limitedly connected to the transmission member. The transmission member includes a belt 6, the first end of the belt 6 is movably connected to a first pulley 61, the first pulley 61 is coaxially connected to the transmission shaft 51, the second end of the belt 6 is movably connected to a second pulley 62, and the second pulley 62 is located at the bottom of the second chamber 22.

[0042] It can be understood that the motor 5 can be built into the first chamber 11, and the transmission member can be arranged in the second chamber 22 of the slide seat 2 in a hidden manner. Under the connection of the through hole A, the transmission shaft 51 can extend from the output shaft end of the motor 4 in the first chamber 11 to the inside of the second chamber 22, and be connected to the first pulley 61 to provide power for the operation of the transmission member.

[0043] In one example, the slider 23 is provided with an anti-skid layer on the first side adjacent to the groove, and at least part of the belt 6 extends from the groove into the notch 21 and abuts against the anti-skid layer. During the operation of the belt 6, the slider 23 slides along the first direction X1 under the involvement of the belt 6.

[0044] It can be understood that the anti-skid layer can be an anti-skid pad bonded to the surface of the slider 23. The anti-skid pad can be made of rubber material. The anti-skid pad can be in contact with the aforementioned belt 6 in the structural position. Due to the friction between one side of the anti-skid pad and the belt 6, the other side of the anti-skid pad is fixedly connected to the slider 23, so that the belt 6 can stably involve the slider 23 in synchronous movement.

[0045] In some embodiments, please refer to Figure 5 and Figure 6 At least one connector 231 is connected to the second side of the slider 23, and a plug-in groove 32 is provided on the side of the baffle 3 adjacent to the slider 23. The plug-in groove 32 and the connector 231 are interference-fitted one by one to ensure that the slider 23 and the baffle 3 are connected in a limited position.

[0046] It can be understood that, through the clamping action between the insertion slot 32 and the connector 231 , the slider 23 and the baffle 3 are embedded in each other to form a stable integral part, so that the slider 23 can involve the baffle 3 to stably move along the first direction X1.

[0047] In some embodiments, the camera shielding device further includes a DMS controller, which is used to identify non-driving behavior of the driver. The DMS controller is electrically connected to the motor 5 to send a control signal to the motor 5 .

[0048] It is understandable that when determining that the driver is in a non-driving behavior state at a certain moment, it is first necessary to limit the vehicle speed to 0. Under this premise, the driving position can be sensed through the camera. On the one hand, if the driver does not appear in the driving position, it can be determined as a typical non-driving behavior. Accordingly, the aforementioned baffle 3 should be in a closed state to block the camera. Further, at this time, the camera can also be controlled to be turned off to reduce the ineffective working time of the camera, which can reduce the power loss of the battery. On the other hand, if the driver appears in the driving position, it is necessary to limit the gear position of the vehicle to P gear at the same time to determine that the current behavior is another typical non-driving behavior. Based on the above two typical non-driving behaviors, the parking scene where the driver is waiting for the red light in D gear can be filtered out. The logic algorithm can accurately screen out the driver's non-driving behavior and can be integrated into the DMS controller.

[0049] In some embodiments, the motor 5 is provided with a forward program and a reverse program and can drive the baffle 3 to move along the inner wall of the slot 21 after receiving a control signal. The number of complete rotations of the motor 4 in a single time has a preset mapping relationship with the height of the slot 21 along the first direction X1.

[0050] It can be understood that the baffle 3 needs to move back and forth along the inner wall of the slot 21 during use, and the power provided by the motor 4 needs to be cut off in time when the slider 23 moves to the end of the slot 21. The motor 4 in the embodiment of the present application has a built-in control algorithm, which can set the maximum number of single rotations of the motor 4 based on the distance that the slider 23 moves along the first direction X1 during one rotation of the output shaft of the motor 4, and the overall size of the slot 21 extending along the first direction X1.

[0051] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 3 The shell assembly also includes a first shell 7 and a second shell 8. The first shell 7 is located at the bottom of the support base 1 to support the support base 1. The two ends of the second shell 8 are respectively connected to the first shell 7 and the support base 1 to lock the two.

[0052] It can be understood that the second shell 8 on one side of the support base 1 is equivalent to a rib, and the overall strength of the structure can be improved by arranging the second shell 8 between the first shell 7 and the support base 1 for connection.

[0053] In one example, the second shell 8 is connected to the first shell 7 by screws, and the material of the screws may be hardened steel. The second shell 8 and the support base 1 may also be connected and fixed by screws made of hardened steel.

[0054] In summary, in the DMS camera shielding device provided in the embodiment of the present application, the camera is placed in the first chamber 11 of the support seat 1. In addition to the slot 21 that can provide a sliding space for the slider 23, the slide seat 2 itself is hollow to form a second chamber 22. The second chamber 22 is connected to the slot 21 through the slot and has a hidden transmission member built in. Part of the structure of the transmission member can pass through the slot and connect with the slider 23. Under the action of the driving member, the transmission member can drive the slider 23 and the baffle 3 to slide along the slot 21, thereby shielding the camera. After identifying non-driving behavior, the camera shielding device of the present application can adaptively shield the camera to protect the privacy in the car.
