The following describes preferred embodiments of the present invention with reference to the accompanying drawings.

Referring to fig. 1 to 3, an embodiment of the present invention provides a driving recorder 100, which includes a housing formed by combining an upper cover 10 and a lower cover 20, and a camera module 30, wherein the camera module 30 is rotatably mounted on the housing.

The housing comprises an upper cover 10 and a lower cover 20 which are detachably connected, the upper cover 10 and the lower cover 20 are folded to form the housing, an inner cavity of the housing is enclosed between the upper cover 10 and the lower cover, and the inner cavity is used for accommodating a circuit board (not shown). Specifically, the bottom cover 20 includes a bottom wall 210 and a side wall 220, and the bottom wall 210 and the side wall 220 enclose a cavity. The sidewall 220 is connected to the upper cover 10, and a through hole 221 penetrating the sidewall 220 is formed in the sidewall 220, and the through hole 221 is used for matching with the camera module 30. That is, the through hole 221 communicates the cavity in the lower cover 20 with the outside. After the upper cover 10 and the lower cover 20 are combined to form the housing, the through hole 221 communicates the inner cavity of the housing with the outside.

The upper cover 10 and the lower cover 20 may be coupled by a snap-fit manner. As shown in fig. 6, the side wall 220 of the lower cover 20 is provided with a plurality of hooks 222 along the circumferential direction, and the upper cover 10 is provided with a plurality of slots 110 corresponding to the plurality of hooks 222. The upper cover 10 and the lower cover 20 are connected together to form a complete housing by the engagement of the hooks 222 with the slots 110. On the basis, the upper cover 10 and the lower cover 20 can also increase the fastening degree by using the screw 50. The screws 50 are inserted into the upper cover 10 and the lower cover 20 in order from a side of the upper cover 10 facing away from the lower cover 20.

The side of the upper cover 10 facing the lower cover 20 may also be provided with a cavity for enclosing the inner cavity of the housing together with the cavity of the lower cover 20. In other embodiments, the side of the upper cover 10 facing the lower cover 20 may be provided relatively flat, i.e. only the cavity in the lower cover 20 is used to form the inner cavity of the housing.

As shown in fig. 1, the upper cover 10 is formed with an attachment area 120 on a side thereof facing away from the lower cover 20. The attachment area 120 is configured as a rectangular plane. In use of the tachograph 100, the attachment area 120 is adhered to the front windshield of the vehicle by an adhesive material.

As shown in fig. 3, in conjunction with fig. 1, the camera module 30 is rotatably installed in the through hole 221 formed in the sidewall 220 of the lower cover 20. Specifically, the camera module 30 includes a camera 310 and a camera housing 320, wherein the camera 310 is mounted in the camera housing 320. The camera housing 320 is a hollow cylindrical structure. The camera 310 includes a rotating portion 311 and a lens 312, wherein one end of the rotating portion 311 extending out of the camera housing 320 is used for being matched with the through hole 221, and the lens 312 is exposed on the cylindrical surface of the camera housing 320 for shooting. In this embodiment, the lens 312 protrudes a certain height from the cylindrical surface of the camera housing 320. In other embodiments, the end surface of lens 312 may be flush with the cylindrical surface of camera housing 320, or the end surface of lens 312 may be slightly lower than the cylindrical surface of camera housing 320.

The rotation portion 311 is rotatably received in the through hole 221. When the rotary part 311 is specifically arranged, the rotary part passes through the through hole 221 and extends into the inner cavity of the shell, and the rotation axis X of the rotary part 311 coincides with the axis of the through hole 221. The rotating portion 311 is sleeved with an elastic washer 40, specifically a rubber ring. The outer ring diameter of the elastic washer 40 is slightly larger than the inner diameter of the through hole 221, so that the elastic washer 40 is pressed against the inner wall of the through hole 221 by means of elastic force. Since the elastic washer 40 has a certain elastic force, the elastic washer 40 provides damping to limit the position of the rotating portion 311 during the rotation of the rotating portion 311, and the camera module 30 can be limited to a certain position without fastening devices such as screws.

When the angle of the camera 310 needs to be adjusted, the vehicle event data recorder 100 of the above embodiment can adjust the camera 310 to a required position only by rotating the camera module 30, and the camera module 30 is kept at the position under the damping action of the elastic washer 40, so that the operation is very convenient.

In order to position the camera module 30 more properly, as shown in fig. 1, the rotating portion 311 is provided with an annular guide groove 3111 along the circumferential direction of the rotating portion 311. As shown in fig. 1 and 3, the upper cover 10 is provided with a first guide 130 extending into the guide groove 3111, and the bottom wall 210 of the lower cover 20 is provided with a second guide 211 extending into the guide groove 3111. The first guide 130 and the second guide 211 limit the rotation portion 311 in the radial direction of the rotation portion 311 from both upper and lower sides; while the first guide 130 and the second guide 211 prevent the camera module 30 from falling off from the housing in the axial direction of the rotating portion 311.

As shown in fig. 1 and 4 to 6, a side of the first guide 130 facing the guide groove 3111 is a concave surface of a circular arc having a radius slightly larger than that of the guide groove 3111. Specifically, the first guide 130 is a rib plate integrally formed with the upper cover 10, and one surface of the rib plate facing the guide groove 3111 is provided with an arc notch to form the arc concave surface. As shown in fig. 1 and 3, a side of the second guide 211 facing the guide groove 3111 is a plane. Specifically, the second guide 211 is a baffle integrally formed with the bottom wall 210 of the lower cover 20, and one surface of the baffle facing the guide groove 3111, that is, the top surface of the baffle, is a flat surface. Through the above means, the plane of the second guide 211 provides a large part for supporting the rotating part 311, and the arc concave surface of the first guide 130 wraps the rotating part 311, thereby achieving a good positioning effect.

Further, the second guiding element 211 is integrally formed with the bottom wall 210 of the lower cover 20, and a side of the second guiding element 211, which is connected to the bottom wall 210 of the lower cover 20, is arc-shaped. With the above design, both the inner and outer surfaces of the bottom wall 210 of the lower cover 20 can be formed in an arc shape, so that the lower cover 20 has a compact and elegant appearance.

As shown in fig. 3, when the upper cover 10 and the lower cover 20 are fastened, the first guide 130 and the second guide 211 respectively extend into the guide groove 3111 from the upper and lower sides, and after the upper cover 10 and the lower cover 20 are fastened, the first guide 130 and the second guide 211 position the camera module 30 through the cooperation with the guide groove 3111.

When the drive recorder 100 is used, the lens 312 of the camera module 30 faces the front of the vehicle. When the angle of the camera 310 needs to be adjusted, the camera 310 is rotated, but at this time, the driver and the passenger cannot observe the position of the camera 310 easily, and the camera 310 may be rotated too much, which may cause easy damage. In addition, it may cause the lens 312 not to normally photograph the subject in front of the vehicle.

In order to solve the above problem, in some embodiments, as shown in fig. 1 and fig. 2, two position-limiting portions are disposed on the rotating portion 311 at intervals along the circumferential direction of the rotating portion 311, which are respectively defined as a first position-limiting portion 3112 and a second position-limiting portion 3113, the bottom wall 210 of the lower cover 20 is provided with a stopping portion 212, the stopping portion 212 is located on the rotation track of the first position-limiting portion 3112 and the second position-limiting portion 3113, and the stopping portion 212 is located between the two position-limiting portions along the circumferential direction of the rotating portion 311. The two limiting portions are bosses, and the stopping portion 212 is a pillar.

When the rotating portion 311 is rotated in the opposite direction, the first and second stopper portions 3112 and 3113 are blocked by the stopper portion 212, respectively, so that the rotation angle of the camera module 30 is limited within the phase difference range of the two stopper portions. Since the range of the rotation angle of the camera module 30 is limited, the driver and the passenger can freely rotate within the range without worrying about the excessively large rotation angle.

Further, in order to ensure that the camera module 30 is within its rotation angle range, the lens 312 can always ensure that the scene in front of the vehicle is captured. With reference to fig. 2 and fig. 3, in some embodiments, the rotation axis of the rotating portion 311 is parallel to the attaching region 120, and the rotation axis of the rotating portion 311 and the lens axis Y of the camera 310 are perpendicular to each other; the camera module 30 has a lens axis Y intersecting the attachment area 120 at all times within its rotation angle range. When the car event data recorder 100 is mounted on the front windshield of the vehicle, the attachment area 120 is bonded to the front windshield, the rotation axis of the rotating portion 311 is parallel to the attachment area 120, and the rotation axis of the rotating portion 311 and the lens axis Y of the camera 310 are set to be perpendicular to each other, so that the lens 312 of the camera 310 rotates in a plane perpendicular to the attachment area 120 and the front windshield. Since the lens axis Y always intersects the attachment area 120, it is ensured that the camera module 30 always faces the front windshield. Therefore, only the attaching area 120 of the automobile data recorder 100 needs to be bonded to the front windshield to ensure that the camera module 30 always faces the front windshield during use.

Specifically, the phase difference between the first stopper 3112 and the second stopper 3113 may be 90 degrees, and the camera module 30 may be rotated in a range of 0 to 90 degrees. In the embodiment, the adjustment angle is 0-90 degrees, so that the device can be compatible with vehicle types such as a trolley, an SUV, a truck and a bus, and can meet the requirement of adjusting the shooting angle of the vehicle types. The traditional vehicle-mounted camera product is limited in size, the rotating structure is limited, and the traditional vehicle-mounted camera product can only be adjusted within the range of 0-60 degrees. Therefore, the driving recorder of the embodiment has obvious technical advantages compared with the traditional technology.

Further, referring to fig. 2 and 3 in combination, the camera module 30 is configured such that when the first position-limiting portion 3112 abuts against the stopping portion 212, the lens axis Y of the camera 310 is perpendicular or substantially perpendicular to the attaching area 120.

Specifically, the extending direction of the first stopper portion 3112 relative to the rotating portion 311 is parallel to the axis of the lens 312, and the first stopper portion 3112 and the lens 312 are located on two sides of the rotating portion 311. The first position-limiting portion 3112 determines a first rotation limit position of the camera module 30 when abutting against the stopping portion 212. When the angle of the camera module 30 needs to be adjusted, only the first position-limiting portion 3112 can rotate and gradually move away from the stopping portion 212, the second position-limiting portion 3113 gradually moves close to the stopping portion 212, and when the second position-limiting portion 3113 abuts against the stopping portion 212, the camera module 30 reaches the second rotation limit position. That is, in the state shown in fig. 2, when the angle of the camera module 30 needs to be adjusted, the camera module 30 can be rotated only along the pointer.

As is well known, the front windshield of the vehicle is obliquely disposed on the vehicle, and when the camera module 30 is at its first rotation limit position, the lens axis Y is perpendicular to the attachment area 120, so the lens axis Y is obliquely upward with respect to the horizontal direction, and at this time, the camera module 30 can only rotate toward its second rotation limit position, so that the lens axis Y undergoes the following changes: is inclined downward, then becomes horizontal, and then is inclined downward. Thereby, the camera module 30 can be adjusted to a very suitable position.

A communication connection is required between the camera module 30 and the circuit board. In order not to affect the design of the rotation mechanism of the camera module 30, in some embodiments, as shown in fig. 1, a cable groove 3114 is formed on an end surface of the rotation portion 311 away from the camera housing 320. The cable connected to the camera 310 passes through the inside of the rotating portion 311, is led out through the cable groove 3114, and is connected to the circuit board. Thus, the cable does not affect the fit between the rotating portion 311 and the first positioning member and the second positioning member, nor the fit between the rotating portion 311 and the through hole 221.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
