Embodiments of the present invention will be described below with reference to the drawings. The following embodiments are described by taking the two-axis tilting device, the camera, and the electronic apparatus of the present invention as examples, and the present invention is not intended to be limited to the following embodiments.

[ embodiment 1 ]

As shown in fig. 1 to 4, a drive recorder 10 as an electronic device according to embodiment 1 includes a camera and a mounting member 500. The photographing apparatus has a camera module 100 as a member to be tilted, and a two-axis driving apparatus for tilting the camera module 100 through two axes. The camera module 100 is connected to a power line 400. The two-axis tilting device includes a frame 200 surrounding the camera module 100 and a tilt driving mechanism for tilting the camera module 100. The tilt drive mechanism has a current supply control assembly and a tilt drive element described later.

The camera module 100 forms a rectangular parallelepiped box. The camera assembly 100 has a generally square front face 110 extending in the X-Y plane, a bottom face 120 parallel to the front face 110, and 4 side faces 130A-130D. The front face 110 is the same general shape and size as the bottom face 120. The front and bottom surfaces 110, 120 may be rectangular. The 4 side surfaces 130A to 130D are substantially rectangular in shape having the same size, and have a predetermined height in the Z-axis direction and a predetermined length in the Y-axis direction or the X-axis direction, respectively. Sides 130A, 130B extend in the Y-Z plane and sides 130C, 130D extend in the X-Z plane.

A lens 140 having an optical axis in the Z-axis direction is disposed on the front surface 110 of the camera module 100. Further, an image pickup device (not shown) that receives light from an object through the lens 140 is disposed in parallel with the lens 140 in the camera module 100. Further, inside the camera module 100, a current supply control module (not shown) for supplying a current to a coil of a tilt driving element described later is designed. Further, a storage medium storage unit (not shown) for storing a storage medium such as an SD card or an image control unit (not shown) for processing an image captured by the image pickup device and storing the image in the storage medium may be provided.

The frame body 200 includes a 1 st gimbal frame 210 and a 2 nd gimbal frame 220. The 1 st gimbal frame 210 and the 2 nd gimbal frame 220 are hollow column members each having both sides open in the Z-axis direction, and surround the periphery of the camera module 100. The 1 st gimbal frame 210 and the 2 nd gimbal frame 220 have substantially the same rectangular shape as viewed in the Z-axis direction, and have long sides and short sides.

The 1 st gimbal frame 210 includes long side plates 211A, 211B and short side plates 211C, 211D. The long side plates 211A, 211B are extended in the Y-Z plane direction, and are long in particular along the dimension in the Y direction. The long side plates 211A, 211B are directly opposed to the side surfaces 130A, 130B of the camera assembly 100 with a certain space therebetween. The short side plates 211C, 211D are extended in the X-Z plane direction, particularly long in the dimension along the X-axis direction. The length of the short side plates 211C, 211D in the X axis direction is shorter than the length of the long side plates 211A, 211B in the Y axis direction. The long side plates 211A, 211B and the short side plates 211C, 211D have a Z-axis direction height substantially equal to that of the camera assembly 100.

Further, notches 212 are formed in four corner portions of the rectangle of the 1 st gimbal frame 210 when viewed from the Z-axis direction. Each cutout portion 212 is formed from the edge on the + Z side of each side plate toward the-Z side to the vicinity of the center. On the inner surfaces of the long side plates 211A, 211B of the 1 st gimbal frame 210, later-described 1 st magnets 620A, 620B are arranged.

The 2 nd gimbal frame 220 includes long side plates 221A, 221B and short side plates 221C, 221D. The long side plates 221A, 221B extend in the X-Z plane direction, and are particularly long along the dimension in the X direction. The long side plates 221A, 221B are directly opposed to the side surfaces 130C, 130D of the camera assembly 100 with a certain space therebetween. The short side plates 221C, 221D are extended in the Y-Z plane direction, particularly long in the dimension along the Y-axis direction. The length of the short side plates 221C and 221D in the Y axis direction is shorter than the length of the long side plates 221A and 221B in the X axis direction. The Z-axis direction height of the long side plates 221A, 221B and the short side plates 221C, 221D is substantially equal to the Z-axis direction height of the camera assembly 100.

Further, notches 222 are formed in four corner portions of the rectangle of the 2 nd gimbal frame 220 as viewed in the Z-axis direction. Each notch 222 is formed from the edge on the-Z side of each side plate toward the + Z side to the vicinity of the center. On the inner surfaces of the long side plates 211A, 211B of the 2 nd gimbal frame 220, later-described 2 nd magnets 620C, 620D are arranged.

The 1 st gimbal frame 210 and the 2 nd gimbal frame 220 have substantially the same shape, and the 2 nd gimbal frame 220 is rotated 180 ° around the X axis or the Y axis and rotated 90 ° around the Z axis from the same arrangement state, and the arrangement structure is such that the 2 nd gimbal frame 220 is combined with the 1 st gimbal frame 210, and the notch portion 222 of the 2 nd gimbal frame 220 is overlapped with the notch portion 212 of the 1 st gimbal frame 210. The notches 212 and 222 are formed to a depth that does not substantially interfere with the operation of the 1 st and 2 nd gimbal frames 210 and 220.

The short side plates 211C, 211D of the 1 st gimbal frame 210 and the long side plates 221A, 221B of the 2 nd gimbal frame 220 are connected by 1 st gimbal shafts 230A, 230B extending in the Y-axis direction. The short side plates 221C, 221D of the 2 nd gimbal frame 220 and the side faces 130A, 130B of the camera assembly 100 are connected by 2 nd gimbal axes 230C, 230D extending in the X-axis direction. Through holes are formed in the centers of the long side plates 211A and 211B of the 1 st gimbal frame 210, and the 2 nd gimbal shafts 230C and 230D pass through the through holes, so that the movement of the 2 nd gimbal shafts 230C and 230D is not disturbed.

Thus, the long side plates 211A, 211B of the 1 st gimbal frame 210 are located inside the short side plates 221C, 221D of the 2 nd gimbal frame 220 while being directly opposite to the sides 130A, 130B of the camera assembly 100. Also, the long side plates 221A, 221B of the 2 nd gimbal frame 220 are located inside the short side plates 211C, 211D of the 1 st gimbal frame 210 while being directly opposite to the sides 130C, 130D of the camera assembly 100. Further, the 2 nd gimbal frame 220 is freely tiltable around the 1 st gimbal axes 230A, 230B, i.e., around the Y axis, with respect to the 1 st gimbal 210. The camera assembly 100 is free to tilt about the 2 nd gimbal axis 230C, 230D, i.e., about the X-axis, relative to the 2 nd gimbal 220.

The bottom surface 120 of the camera assembly 100 is connected to a power cord 400. The power line 400 supplies power to the current supply control module, the storage medium storage unit, and the image control module stored in the camera module 100.

The mounting member 500 includes a bar 510 and a fixing member 520. One end 510A of the bar 510 is fixed to the frame body 200, for example, to the outer face of the short side plate 211D of the 1 st gimbal frame 210. The other end 510B of the rod 510 is formed with a sphere 510C. The fixing member 520 includes a fixing plate 521 having an adhesive surface to be adhered to the front glass of the vehicle, and a cylindrical portion 522 protruding on the opposite side of the adhesive surface. The cylindrical portion 522 and the spherical body 510C constitute a so-called ball coupling, and the cylindrical portion 522 supports the spherical body 510C, and the rod 510 is supported so that the direction and angle can be adjusted with respect to the fixing member 520 with a certain degree of freedom.

The tilt driving element is composed of coils disposed on the side surfaces 130A to 130D of the camera module 100, and magnets disposed on the inner surfaces of the long side plates 211A and 211B of the 1 st gimbal frame 210 and the long side plates 221A and 221B of the 2 nd gimbal frame 220 of the frame body 200, respectively. The coils of the side surfaces 130A to 130D include 1 st coils 610A and 610B and 2 nd coils 610C and 610D. The magnets on the inner surfaces of the long side plates 211A, 211B, 221A, 221B include the 1 st magnets 620A, 620B and the 2 nd magnets 620C, 620D. Specifically, the 1 st coils 610A and 610B are disposed on the side surfaces 130A and 130B perpendicular to the X-axis direction. The 2 nd coils 610C and 610D are disposed on the side surfaces 130C and 130D perpendicular to the Y-axis direction. As shown in fig. 4, the 1 st yoke 630 may be embedded in the side surfaces 130A and 130B, and the 2 nd yoke 640 may be embedded in the side surfaces 130C and 130D.

The 1 st coils 610A, 610B each have an elliptical shape elongated in the Y axis direction, and each include 2 linear portions extending in the Y axis direction and a C-shaped bent portion connecting both ends thereof. Similarly, the 2 nd coils 610C and 610D each have an elliptical shape elongated in the X axis direction and are composed of 2 linear portions extending in the X axis direction and C-shaped curved portions connecting both ends thereof. The 1 st coils 610A, 610B and the 2 nd coils 610C, 610D are connected to a current supply control module (not shown) designed inside the camera module 100.

On the other hand, the 1 st magnets 620A and 620B are disposed on the inner surfaces of the long side plates 211A and 211B of the 1 st gimbal frame 210, respectively. The 2 nd magnets 620C and 620D are disposed on the inner surfaces of the long side plates 221A and 221B of the 2 nd gimbal frame 220, respectively.

The 1 st magnets 620A and 620B are each formed of 2 plate-like magnet pieces having different magnetic pole faces, which are long in the Y-axis direction, and are arranged in the Z-axis direction. The 2 nd magnets 620C and 620D are also each formed of 2 plate-like magnet pieces having different magnetic pole faces and long in the X-axis direction, and are arranged in the Z-axis direction. Therefore, the 1 st coil 610A, 610B has a linear portion facing the 1 st magnet 620A, 620B with a fixed space therebetween, and the 2 nd coil 610C, 610D has a linear portion facing the 2 nd magnet 620C, 620D with a fixed space therebetween. The 1 st magnets 620A, 620B and the 2 nd magnets 620C, 620D, which are divided in the Z axis direction and have different magnetic pole surfaces, may face the 1 st coils 610A, 610B and the 2 nd coils 610C, 610D with a certain space therebetween.

An example of assembling the automobile data recorder 10 of the above embodiment will be explained below. The power supply line 400 is connected to the bottom surface 120 of the camera module 100, and the coils are mounted on the side surfaces 130A to 130D. The magnets are attached to the inner surfaces of the long side plates 211A and 211B of the 1 st gimbal frame 210 and the long side plates 221A and 221B of the 2 nd gimbal frame 220, respectively. The 2 nd gimbal frame 220 is combined with the 1 st gimbal frame 210 such that the cutout portion 222 of the 2 nd gimbal frame 220 overlaps with the upper portion of the cutout portion 212 of the 1 st gimbal frame 210. Further, the short side plates 211C, 211D of the 1 st gimbal frame 210 and the long side plates 221A, 221B of the 2 nd gimbal frame 220 are connected by the 1 st gimbal shafts 230A, 230B.

Subsequently, the camera module 100 is inserted into the frame body 200. I.e., into the interior of the 1 st and 2 nd gimbal frames 210 and 220. Further, the side surfaces 130A, 130B of the camera assembly 100 are connected to the short side plates 221C, 221D of the 2 nd gimbal frame 220 through the 2 nd gimbal shafts 230C, 230D. Thus, the camera assembly 100 may tilt about the 2 nd gimbal axes 230C, 230D relative to the 2 nd gimbal 220, with the 2 nd gimbal frame 220 being in a state of being tiltable about the 1 st gimbal axes 230A, 230B relative to the 1 st gimbal frame 210. In other words, the camera assembly 100 is in a state tiltable with respect to the 1 st gimbal frame 210 in the X-axis direction and the Y-axis direction.

In this case, the linear portions of the 1 st coils 610A and 610B face the different magnetic pole surfaces of the 1 st magnets 620A and 620B with a predetermined space therebetween, and the linear portions of the 2 nd coils 610C and 610D face the different magnetic pole surfaces of the 2 nd magnets 620C and 620D with a predetermined space therebetween.

Further, one end 510A of the bar 510 of the mounting member 500 is fixedly attached to the short side plate 211D of the 1 st gimbal frame 210 of the frame body 200, and the spherical body 510C of the other end 510B is inserted into the cylindrical member 522 of the fixing member 520.

Next, the operation of the drive recorder 10 of the present embodiment will be described. For example, each coil is supplied with current from a current supply control module to be energized. In the magnetic field generated by each magnet, the current flowing through each coil causes the coil to generate electromagnetic force in the Z-axis direction.

The current flowing through the 1 st coil 610A and the 1 st coil 610B is the same. In this case, the 1 st coil 610A and the 1 st coil 610B generate forces in the Z-axis direction in opposite directions according to the current direction and the selection of the magnetic pole surfaces of the 1 st magnets 620A and 620B. Thereby, rotation thereof about the Y axis relative to the camera assembly 100 can be achieved.

Similarly, in the case of the 2 nd coils 610C and 610D, when the same current flows, the 2 nd coil 610C and the 2 nd coil 610D generate forces in the Z-axis direction in opposite directions. Thereby, rotation thereof about the X-axis relative to the camera assembly 100 can be achieved.

The current supply control component of the camera component 100 has an angular velocity detection element (not shown). Vibration or shock during the operation of the vehicle is transmitted to the camera assembly 100, and each of the X-axis peripheral component and the Y-axis peripheral component is detected by the angular velocity detection element. The current supply control unit supplies current to the 2 nd coils 610C and 610D and/or the 1 st coils 610A and 610B of the camera assembly 100 or adjusts the supply amount and direction of current according to the magnitude and direction of the detected angular velocity of the components around the X-axis and/or the Y-axis. This causes the camera module 100 to generate a force to rotate around the X-axis and/or around the Y-axis, and to return to the original direction around the X-axis and/or the Y-axis. Thus, the camera assembly 100 is blocked from wobbling in the vehicle.

The frame body 200 may also have a casing that covers the 1 st and 2 nd gimbal frames 210 and 220 from the further outside. It may be fixed to the inner surface of the housing using the 1 st gimbal frame 210 and the installation part 500 is installed to the outer surface. Also, the housing may cover the outside of the ± Z side of the camera assembly 100.

[ 2 nd embodiment ]

A drive recorder 10A according to embodiment 2 differs from the drive recorder 10 according to embodiment 1 in that a back plate is provided, the 1 st gimbal frame 210 is supported so as to be rotatable around the Z axis, and the mounting member 500 is provided on the back plate. The other configurations of the camera module 100 are the same except that the 3 rd coil is disposed on the bottom surface 120 of the module and the 3 rd magnet is provided on the back plate to face the coil. In the following description, the same reference numerals are given to the same components as those of embodiment 1, and detailed description of the corresponding components is omitted.

The frame body 200 of the drive recorder 10A according to embodiment 2 includes a back panel 700. The rear plate 700 is a flat rectangular plate extending in the X-Y plane direction, and has substantially the same outer shape as the frame body 200 when viewed in the Z-axis direction, but may have another shape. One edge of the back panel 700 is connected to one end 510A of the bar 510 of the mounting member 500. A bearing 710 is formed in the center of the back plate 700.

The automobile data recorder 10A includes a connecting member that connects the 1 st gimbal frame 210 and the back panel 700. The connecting member includes a band-shaped flat plate portion 810 and arm portions 820 bent and protruding from both ends thereof in the Z-axis direction, and the band-shaped flat plate portion 810 extends parallel to the bottom surface 120 of the camera module 100 and the back panel 700. A shaft 830 protruding in a direction opposite to the protruding direction of the arm 820 is provided at the center of the flat plate portion 810. Distal ends of the arm portions 820 are connected to the rear panel 700-side ends of the long side panels 211A and 211B of the 1 st gimbal frame 210. Shaft 830 is inserted into bearing 710 of back plane 700. Thus, the 1 st gimbal frame 210 may rotate about the Z-axis relative to the back panel 700.

4 3 rd coils 840A to 840D are fixed to the bottom surface 120 of the camera module 100. On the other hand, on the surface of the back plate 700 facing the bottom surface 120 of the camera module 100, 3 rd magnets 850A to 850D are arranged, facing the 3 rd coils 840A to 840D, respectively, with a certain space therebetween.

The power line 400 is connected to the bottom surface 120 of the camera module 100, avoiding the connecting member and the 3 rd coils 840A to 840D. In the back panel 700, a lead-out opening 720 is formed at a position corresponding to a portion of the power supply line 400 connected to the bottom surface 120 of the camera module 100, and the power supply line 400 is led out to the outside.

The 3 rd coils 840A to 840D are connected to a current supply control unit (not shown) of the camera unit 100, and supply the same current to the 3 rd coils 840A to 840D based on a Z-axis peripheral angular acceleration component detected by an angular acceleration detection element (not shown), or adjust the supply direction and supply amount of the current. Then, an electromagnetic force for rotating the camera module 100 around the Z axis is generated by a current flowing in the magnetic field generated by the 3 rd magnets 850A to 850D, and the camera module can be returned to the original direction around the Z axis.

In addition, a yoke may be provided between the 3 rd coils 840A to 840D on the bottom surface 120 of the camera module 100. Also, the back panel 700 may also be designed to cover the 1 st gimbal frame 210, the 2 nd gimbal frame 220, and a portion of the housing of the camera assembly 100. The 3 rd coils 840A to 840D may be provided on the back panel 700, and the 3 rd magnets 850A to 850D may be provided on the camera module 100. Further, if the 3 rd coils 840A to 840D and the 3 rd magnets 850A to 850D generate driving forces in the tangential direction of the circumference around the shaft 830, at least 1 group may be present.

Further, although the above embodiment has described the example in which the present invention is applied to the drive recorder, the application target of the present invention is not limited to the drive recorder, and the present invention can be applied to a camera mounted on a bicycle or an unmanned aerial vehicle.
