[ detailed description ] embodiments

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.

As shown in fig. 1 and 2, a drive recorder 10 as an electronic device according to the present embodiment 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 body 200 surrounding the camera module 100, a suspension spring 300 connecting the camera module 100 and the frame body 200, and a tilt driving mechanism for tilting the camera module 100. The tilt driving mechanism has a current supply control component (not shown) described later and a tilt driving element 600.

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. Further, an image pickup device (not shown) is disposed in the camera module 100 in parallel with the lens 140 and receives light from the subject through the lens 140. Also, inside the camera assembly 100, a current supply control assembly that supplies current to a coil of the tilt driving element 600 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 back-side frame body 210 and a frame body side plate 220. The rear frame 210 includes a rectangular rear plate 211 extending in the X-Y plane direction, and 4 rear side plates 212A to 212D extending from the periphery of the rear plate 211 in the Z-axis direction. The back panel 211 is larger in size than the bottom surface 120 of the camera assembly 100. In other words, the length of the back plate 211 in the X-axis direction and the length of the back plate in the Y-axis direction are greater than the length of the bottom surface 120 in the X-axis direction and the length of the back plate in the Y-axis direction.

The frame body side plate 220 surrounds the camera module 100, has two open hollow square pillar portions on both sides in the Z-axis direction, and includes 4 frame body side plates 220A to 220D. The Y-axis direction lengths of the frame body side plates 220A to 220B and the X-axis direction lengths of the frame body side plates 220C and 220D are equal to the Y-axis direction lengths of the back side plates 212A and 212B and the X-axis direction lengths of the back side plates 212C and 212D, respectively, and are greater than the Y-axis direction lengths of the side surfaces 130A and 130B and the X-axis direction lengths of the side surfaces 130C and 130D of the camera module 100. Therefore, when the camera module 100 is disposed in the frame body 200, the side surfaces 130A to 130D face each other without contact with a certain space with respect to the frame body side plates 220A to 220D.

The suspension spring 300 is disposed between the bottom surface 120 of the camera module 100 and the back plate 211 of the frame body 200, and connects the two. The suspension spring 300 is disposed at the center of the bottom surface 120. The suspension spring 300 may also be disposed at a position of the bottom surface 120 corresponding to the center of gravity of the camera assembly 100. Further, 2 or more suspension springs 300 may be disposed on the bottom surface 120.

As shown in fig. 3, each suspension spring 300 includes a spring body 310, a 1 st mounting portion 311 formed at one end of the spring body 310 and mounted on the back surface plate 211, and a 2 nd mounting portion 312 formed at the other end and mounted on the bottom surface 120. In the present embodiment, the 1 st attaching portion 311 is formed at the outer end portion, and the 2 nd attaching portion 312 is formed at the inner end portion. The spring body portion 310 is formed by punching through a metal plate body, and is in a Spiral spring (helical spring) shape wound around the Z axis in the X-Y plane. When mounted, the plate surface of the spring body portion 310 is expanded in the X-Y plane direction. In the present embodiment, the spring body portion 310 reaches the 2 nd mounting portion 312 from the 1 st mounting portion 311 by winding 2 turns around the Z axis. The number of winding turns of the vortex can be less than 2 turns or more than 2 turns. Further, it is preferable that the 1 st mounting part 311 and the 2 nd mounting part 312 are designed to be very close to each other.

The 1 st attachment portion 311 is a rod-shaped member extending from one end of the spring body portion 310 so as to be bent substantially perpendicularly in the Z-axis direction. The 1 st mounting portion 311 is fixedly connected to the rear plate 211 of the rear frame 210. The 2 nd mounting portion 312 is a rod-shaped member that is bent and extended from one end of the inside of the spring body portion 310 in the Z-axis direction substantially perpendicularly to the 1 st mounting portion 311. The 2 nd mounting portion 312 is fixedly attached to the bottom surface 120 of the camera module 100. In this case, the spring body portion 310 does not contact both the bottom surface 120 and the back panel 211 of the camera assembly 100. Thus, the 1 st mounting part 311 and the 2 nd mounting part 312 are close to form a straight line, and the 2 nd mounting part 312 may be inclined with respect to the 1 st mounting part 311 with the Z-axis direction as an axis. In other words, it can rotate around the X-axis as well as the Y-axis.

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. Back side plate 212B and back plate 211 form a cutout 230. The cutout portion 230 is a lead-out port for pulling out the power cord 400.

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 frame body side plate 220D. 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 rod 510 is supported by the cylindrical portion 522 so as to enclose the spherical body 510C, and can be adjusted in direction and angle with respect to the fixing member 520 with a certain degree of freedom.

The tilt driving element 600 includes a coil 610 disposed on the side surfaces 130A to 130D of the camera module 100, and magnets 620 disposed on the inner surfaces of the frame side plates 220A to 220D of the frame 200. The coil 610 has 1 st coils 610A, 610B and 2 nd coils 610C, 610D. The magnets 620 include 1 st magnets 620A and 620B and 2 nd magnets 620C and 620D. Specifically, the 1 st coils 610A and 610B are disposed on the side surfaces 130A and 130B perpendicular to the X-axis direction. On the other hand, the 2 nd coils 610C and 610D are disposed on the side surfaces 130C and 130D perpendicular to the Y-axis direction.

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 coil 610A, 610B and the 2 nd coil 610C, 610D are connected with a current supply control component provided inside the camera component 100.

On the other hand, the frame side plates 220A and 220B are provided with 1 st magnets 620A and 620B. Further, the frame body side plates 220C and 220D are provided with the 2 nd magnets 620C and 620D.

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 each formed of 2 plate-like magnet pieces having different pole faces and long in the X-axis direction, and are arranged in the Z-axis direction. The 1 st coils 610A, 610B have linear portions facing the 1 st magnets 620A, 620B with a predetermined space therebetween. The 2 nd coils 610C and 610D have linear portions facing the 2 nd magnets 620C and 620D with a fixed space therebetween. In a modification, 1 of 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, face each other with a certain space apart from the linear portions of the 1 st coils 610A, 610B and the 2 nd coils 610C, 610D.

An example of assembling the automobile data recorder 10 of the present embodiment will be explained below. The power supply line 400 is connected to the bottom surface 120 of the camera module 100, and the coil 610 is mounted on the side surfaces 130A to 130D. The 2 nd mounting part 312 of the suspension spring 300 is connected to the bottom surface of the camera module 100. On the other hand, the 1 st mounting portion 311 of the suspension spring 300 is connected to the back plate 211 of the back frame 210. Thereby, the camera module 100 is suspended by the frame body 200 through the suspension springs 300. Magnets 620 are attached to the inner surfaces of the frame side plates 220A to 220D, respectively.

Subsequently, the camera module 100 is inserted into the frame body side plate 220. And the frame body side plate 220 is mounted with respect to the back side frame body 210. Specifically, the rear ends of the frame side plates 220A to 220D in the Z-axis direction are butted against and fixed to the front ends of the rear side plates 212A to 212D of the rear side frame 210 in the Z-axis direction. In this case, the power supply line 400 is pulled out of the frame 200 through the notch 230 of the rear frame 210. Thereby, the camera module 100 is in a state tiltable inside the frame body 200.

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.

One end 510A of the bar 510 of the mounting member 500 is fixedly connected to one of the frame side plates 220 of the frame 200 (the frame side plate 220D in fig. 1 and 2), and the ball 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, the coil 610 is energized by supplying current from a current supply control component. In the magnetic field generated by the magnet 620, the current flowing through the coil 610 causes the coil 610 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.

In the suspension spring 300, the two perforated plate ends may be bent into the 1 st mounting portion 311 and the 2 nd mounting portion 312, respectively. Further, 1 wire may be formed in a spiral shape, and both ends may be bent as the 1 st mounting portion 311 and the 2 nd mounting portion 312 as the spring body portion 310. Further, the spring body 310 may be a coil spring (coil spring) instead of a spiral shape. 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.
