Description

Technical Field

[0001] The utility model relates to a vehicle-mounted recorder, in particular to a vehicle-mounted recorder with multiple cameras. Background Art

[0002] A vehicle-mounted recorder is a tool for monitoring or recording the driving process. In order to avoid false alarms or misjudgments during vehicle driving, some vehicle-mounted recorders are equipped with multiple cameras. Through different scene analyses, the road conditions during vehicle driving can be judged more accurately to ensure the safety of the driver.

[0003] In order to achieve multi-angle shooting, some vehicle-mounted recorders are also provided with a rotating structure to control the synchronous rotation of multiple cameras. For example, a dual-camera angle-adjustable structure disclosed in Chinese Utility Model CN208881714U. This angle-adjustable structure uses the rotation of two connecting rods to drive two sliding members to move in an arc-shaped waist groove respectively, thereby driving the camera to rotate around a fulcrum.

[0004] However, the above rotation method requires turning two connecting rods simultaneously, which is inconvenient to operate. In addition, if the rotation angles of the two connecting rods are inconsistent, torsion will be generated on the rotating bracket, which is likely to cause the problem of the rotating bracket breaking. Summary of the Utility Model

[0005] In order to overcome the disadvantages and deficiencies existing in the prior art, the purpose of the utility model is to design a vehicle-mounted recorder with dual cameras, which can ensure the synchronous rotation of multiple cameras, is convenient to operate, and is not prone to the problem of damage to the rotating bracket.

[0006] To achieve the above purpose, the utility model provides a vehicle-mounted recorder with multiple cameras, including: a housing, a rotating bracket, multiple cameras and a knob. The rotating bracket and the knob are rotatably arranged on the housing. Multiple cameras are all fixed on the rotating bracket and arranged in a row along the left-right direction. It is characterized in that: the knob is fixedly connected to the rotating bracket, and the rotation center of the knob is collinear with the rotation center of the rotating bracket.

[0007] Furthermore, a side hole is provided on the side wall of the housing. A part of the knob is located in the side hole, and the other part of the knob is located inside the housing. Among them, the above structure is equivalent to completely hiding the knob in the housing without any exposed part, which can avoid accidental touch of the knob by the user.

[0008] Further, a plurality of ridges are provided in the side holes, and the plurality of ridges are arranged in a 360° circular array around the median line of the side holes. A shrapnel is provided on the peripheral wall of the knob, and the shrapnel abuts against the positions between two adjacent ridges. Among them, the setting of the plurality of ridges and the shrapnel can not only allow the user to cooperate with the rotation angle, but also play a certain positioning role for the knob and the rotating bracket, so that the two maintain an angle without external force.

[0009] Further, a support plate is provided inside the housing; a rotating rod and a rotating shaft are respectively provided at two side ends of the rotating bracket. The rotating rod is fixed to the knob, and the rotating shaft is rotatably arranged on the support plate. When the knob rotates, it will drive the rotating rod to rotate, so that the entire rotating bracket rotates relative to the support plate.

[0010] Further, a key position protrudes from the peripheral wall of the rotating rod, and a key groove is provided at the inner end of the knob. The key position is inserted into the key groove and forms a tight fit. Among them, through the cooperation of the key position and the key groove, the knob can drive the rotating bracket to rotate.

[0011] Further, the vehicle-mounted recorder further includes: a screw; a screw hole is provided at the outer end of the rotating rod, and the screw passes through the knob and meshes with the screw hole. Among them, the knob and the rotating rod are fixed by screwing the screw.

[0012] Further, an elastic barb is further provided on the peripheral wall of the knob. The barb is located inside the housing and at least a part of the barb is directly opposite to the side wall of the housing in the left-right direction. Among them, the setting of the barb can avoid the problem of the knob falling off after unscrewing the screw.

[0013] Further, a plurality of positioning cylinders are provided at the front end of the rotating bracket, and a plurality of cameras are respectively embedded in the plurality of positioning cylinders. Among them, the positioning cylinder can play a protective role for the camera.

[0014] Further, a plurality of camera holes and a plurality of inclined grooves are provided on the front wall of the housing. A plurality of cameras respectively pass through the plurality of camera holes. The depth of the inclined groove gradually decreases from top to bottom, and the camera hole is located at the top of the inclined groove. Among them, the setting of the inclined groove can not only limit the rotation angle range of the camera, but also play a protective role for the camera.

[0015] Further, the vehicle-mounted recorder further includes: a circuit board, and the circuit board is fixed to the rotating bracket and is electrically connected to the camera. Among them, fixing the circuit board to the rotating bracket can make the circuit board rotate synchronously with the camera, avoiding interference between the wire and the rotating bracket.

[0016] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: Since the rotation center of the knob is collinearly arranged with the rotation center of the rotation bracket in the vehicle-mounted recorder of the present utility model, only one knob can be used to control the synchronous rotation of multiple cameras, which is convenient to operate. At the same time, it can avoid the rotation bracket from being damaged due to torsion, and the rotation angle is accurate. BRIEF DESCRIPTION OF THE DRAWINGS
