Since the elastic body is sandwiched between the end faces of the side end portions and the convex portions around the rear side end portions are pressed by a frame-like member and attached to the holding body, the case and the holding body Since the elastic body sandwiched between the two absorbs and reduces the impact and vibration applied to the camera module from the outside, it is possible to prevent the occurrence of breakage of the constituent members including the cracking of the lens.

  According to the camera module of the present invention, when the elastic body is annular along the outer peripheral portion of the end surface of the rear end portion of the case, the impact is uniformly applied to the outer peripheral portion of the end surface of the rear end portion of the case. In addition to absorbing and mitigating vibrations, it is possible to ensure waterproofness between the case and the holding body.

  According to the camera module of the present invention, when the elastic body is made of rubber or resin, it absorbs and relaxes shock and vibration as an annular elastic body and secures waterproofness between the case and the holding body. It becomes suitable for.

  Further, according to the camera module of the present invention, when the convex portion of the end surface of the rear end portion of the case is a flange portion projecting around the end surface, the flange portion is pressed by the frame-like member to Since the elastic body can be uniformly compressed around the end face of the side end, it absorbs and relaxes shock and vibration well, and the posture with the case attached to the holding body is stable and good It is possible to hold with high positional accuracy.

  Further, according to the in-vehicle camera of the present invention, since the camera module of the present invention is attached to the vehicle via the holding body, the camera module absorbs and reduces the impact and vibration accompanying the movement of the vehicle. In addition, since it is possible to prevent damage to the structural members including the lens, it is possible to provide a highly reliable on-board camera with excellent durability.

  Hereinafter, the camera module of the present invention will be described in detail with reference to the accompanying drawings. In the following description, the lens is disposed on the front side of the camera module, while the opposite side is referred to as the rear side.

  FIG. 1A is an exploded perspective view showing an example of an embodiment of a camera module of the present invention, and FIG. 1B is a perspective view showing a state in which they are assembled. 2A is a plan view of the camera module main body of the example shown in FIG. 1 as viewed from the front side, and FIG. 2B is a cross-sectional view taken along the line AA shown in FIG. It is. In the cross-sectional view of FIG. 2B, the case 1 is not shown in cross section, and the side view is shown.

  As shown in FIGS. 1 and 2, the camera module 10 of this example is a camera module 10 in which a lens 3 is attached to a front end portion of a case 1 and a rear end portion is attached to and held by a holding body 5. Then, the case 1 is sandwiched between the elastic body 6 so that the holding body 5 and the end surface 1a of the rear end portion do not contact each other, and the convex portion 2 around the rear end portion is formed by the frame-shaped member 4. It is pressed and attached to the holding body 5. Such a camera module 10 is used as a small on-board camera, an electronic camera, and an in-vehicle camera. When used as an in-vehicle camera, it has a function of imaging the surroundings of a vehicle, imaging of white lines on a road, or the blind spot of a driver driving a vehicle, for example, on a display installed in front of a driver's seat An image is displayed, or an image signal is used in an ECU (Electronic Control Unit) that controls driving of an automobile.

  The case 1 has a lens 3 attached to a front end portion and a rear end portion attached to and held by a holding body 5, and has an image pickup device such as a CCD image sensor or a CMOS image sensor in an internal space. The semiconductor image sensor element is accommodated. As shown in FIG. 2B, the case 1 of the present example includes a front part 1b on the front side where the lens 3 is mounted, and a rear part on which the imaging element is housed and a convex part 1a is formed at the rear end. The rear part 1c is joined and configured.

  Such a case 1 is formed in a predetermined shape by molding using a resin material by, for example, injection molding. As the resin of the case 1, for example, a resin such as polycarbonate (PC) or polyphthalamide (PPA) is used to ensure necessary durability and reduce weight. Usually, it is preferable to use the same resin material for both in order to suppress the generation of thermal stress between the two by combining the thermal expansion and thermal contraction of the front part 1b and the rear part 1c. Depending on the specifications, a metal material or a different resin material may be used.

  In the camera module 10 of this example, the convex portion 2 provided around the rear end portion of the case 1 is configured as a flange portion 2 projecting around the end surface 1a. Thus, if the convex part 2 is made into the flange part 2, the rear side edge part of case 1 can be uniformly hold | suppressed by the frame-shaped member 4, and it can attach to the holding body 5, and the positional accuracy of attachment of case 1 is favorable. It is preferable because the posture of the case 1 is stable. In addition, you may provide the convex part 2 as a some protrusion-shaped part in the rear side edge part of case 1. As shown in FIG. In the case where a plurality of projecting convex portions 2 are provided, it is preferable that they are arranged substantially uniformly around the rear end portion of the case 1 in order to stabilize the mounting position accuracy and the case 1 posture. When the outer periphery of the case 1 has a quadrangular shape as in this example, one or more may be arranged at the center of each side of the quadrangle. A plurality of them may be arranged at substantially equal intervals.

  Further, in the camera module 10 of this example, when the flange portion 2 is pressed by the frame-like member 4, the positional accuracy of the flange portion 2 is ensured and the positional accuracy of mounting the case 1 is stabilized and good. In addition, projections 2 a for setting a reference surface are provided at three locations on the front surface where the flange portion 2 comes into contact with the frame-like member 4.

  The lens 3 is for condensing subject light on the image sensor housed in the case 1. Usually, a lens having a convex shape on the front side for condensing subject light at a wide angle, It is configured as a lens group composed of a plurality of lenses for focusing the light that has passed through the lens in a state where there is no image distortion in the image sensor. In the camera module 10 of this example, the mounting structure of the lens 3 is not shown, but there is no particular restriction on the structure, and a structure as disclosed in Patent Document 1 may be adopted.

  The frame-like member 4 is combined with the case 1 so as to surround the outer periphery of the rear end portion of the case 1 and holds the convex portion 2 such as the flange portion 2 provided around the rear end portion of the case 1. This is for attaching the case 1 to the holding body 5 by pressing against the body 5. By positioning the convex portion 2 of the case 1 by the frame-like member 4 and attaching it to the holding body 5, the positioning of the case 1 in the direction parallel to the surface of the holding body 5 (left-right direction, XY direction) can be performed with high accuracy. Can do. Further, by setting the height of the frame-shaped member 4 from the surface of the holding body 5 and the height of the inner portion that contacts the convex portion 2, the positional accuracy in the mounting height direction (front-rear direction, Z direction) of the case 1 is determined. In addition, the deformation amount of the elastic body 6 can be set stably in a good state.

  In order to attach the frame-shaped member 4 to the holding body 5, the frame-shaped member 4 may be screwed to the holding body 5, or from the frame-shaped member 4 to the holding body 5 side as shown in FIG. It is also possible to extend the fitting hook (claw-shaped claw) 4 a and fit the hook into the fitting hole 5 b provided in the holding body 5.

  In addition, by providing a plurality of protruding portions in which holes for passing screws or pins are formed at a plurality of locations on the outer periphery of the frame-shaped member 4 and stopping the screws and pins passed through the holes on the holding body 5, The member 4 may be attached to the holding body 5. In both cases where hooks and holes are provided in the main body of the frame-shaped member 4 and in the protruding portion, the holding force of the convex portion 2 of the case 1 and the pressing force to the elastic body 6 are substantially uniform in the circumferential direction of the case 1. It is preferable to arrange them in a well-balanced manner so that they can be obtained.

  The shape of the frame-shaped member 4 needs to match the shape of the inner periphery with the shape of the outer shape of the case 1, but the shape of the outer periphery may be freely selected according to the specifications required for the camera module 10. . If the shape of the outer periphery of the case 1 and the shape of the inner periphery of the frame-like member 4 are rectangular as in the camera module 10 of this example, the orientation of the lens 3 around the optical axis is easily set as set when the case 1 is attached. It is possible to regulate, and it is also possible to regulate movement that rotates around the optical axis due to impact. Further, in order to restrict the rotation around the optical axis in the case of a circular shape, a guide rail mechanism or a guide pin mechanism may be used as in the camera module 10 of this example.

  In order to easily and satisfactorily ensure the positional accuracy between the case 1 and the frame-like member 4, a guide mechanism may be provided on the case 1 and the frame-like member 4. In the camera module 10 of this example, a guide rail 1d is formed on the outer periphery of the rear end portion of the case 1 at the center of each side of the rectangular outer periphery, and the guide rail 1d is disposed at a corresponding position on the frame-like member 4. A cutout 4b is provided. By adopting such a guide rail 1d and notch 4b structure as the guide mechanism, it is possible to easily and satisfactorily assure the positional accuracy of assembly and mounting, and impact and vibration are applied from the outside. Sometimes, the case 1 can move along the guide rail 1d in the direction in which the elastic body 6 is pressed, so that the impact and vibration absorption / relaxation effects of the elastic body 6 are not hindered. In addition, if the guide rail 1d is arranged in a non-symmetrical manner rather than symmetrically on the outer periphery of the case 1, there is no mistake in the direction in the direction around the optical axis when the case 1 is attached. It will be easy to do without.

  Such a frame-shaped member 4 is also formed into a predetermined shape by molding using a resin material by, for example, injection molding. As the resin of the frame member 4, for example, a resin such as polycarbonate (PC) or polyphthalamide (PPA) is used to ensure necessary durability and reduce the weight. Usually, it is preferable to use the same resin material for both the case 1 and the holding body 5 in order to suppress the occurrence of thermal stress between them in order to match the thermal expansion and thermal contraction of the case 1 and the holding body 5. Depending on the required specifications, a metal material or a different resin material may be used.

  The holding body 5 is a holding member as a so-called bracket or base in which the case 1 is attached and held by pressing the convex portion 2 with the frame-like member 4. The holding body 5 is provided with a concave portion 5c and a frame-like member 4 for preventing the displacement of the elastic body 6 at a portion facing the end surface 1a of the rear end portion of the case 1 and sandwiching the elastic body 6 therebetween. A fitting hole 5b for mounting and a screw hole are provided. The camera module 10 also has a structure (not shown) for installing it at a desired installation location. In the example shown in FIG. 2B, a wiring hole 5a for passing a wiring cable (not shown) drawn from the case 1 is provided on the inner side where the elastic body 6 is disposed. In this example, the wiring hole 5a is provided on the inner side of the annular elastic body 6 between the end face 1a of the case 1 and the holding body 5, so that the elastic body 6 can waterproof the holding body 5 from the holding body 5 to the case 1 side. It is also possible to secure the sex.

  As a material for such a holding body 5, it is preferable to select a material having a sufficiently small strength with respect to an allowable stress by an impact force and a reaction force of the elastic body 6. In addition, in consideration of creep deformation due to heat from the atmosphere at the time of use, it is preferable to select one having as little deformation as possible.

  The surface of the holding body 5 is preferably as smooth as possible in the surface accuracy of the portion with which the elastic body 6 abuts. In particular, when the holding body 5 is a resin molded product, it is preferable to take care not to place a parting line by nesting or sliding on the installation surface of the elastic body 6. The flatness and surface roughness of the surface of the holding body 5 may be appropriately selected in consideration of a crushing amount for elastically deforming and holding the elastic body 6 and a sealing property for ensuring waterproofness.

  Such a holding body 5 is also formed into a predetermined shape by molding using a resin material by injection molding, for example. As the resin of the holding body 5, for example, a resin such as polycarbonate (PC) or polyphthalamide (PPA) is used to ensure the required durability and reduce the weight. Usually, in order to suppress thermal stress between the case 1 and the frame-like member 4 together with the thermal expansion and contraction, it is preferable to use the same resin material for both. Depending on the specifications required, a metal material or a different resin material may be used.

  The elastic body 6 is disposed between the end surface 1 a and the holding body 5 so that the end surface 1 a of the rear end portion of the case 1 does not contact the holding body 5. It is interposed between the end surface 1a of the part and the holding body 5 and has a function of absorbing and mitigating external shocks and vibrations while securing the mounting position and positional accuracy of the case 1 using elasticity. . In the camera module 10 of the present example, the elastic body 6 is shown as a quadrangular ring-shaped one, but a plurality of round and long granular shapes, elongated string shapes, hook-shaped shapes, etc. are arranged. It may be.

  In the case of a ring-like material such as the elastic body 6 in this example, ethylene propylene rubber (EPDM), nitrile rubber (NBR), silicone rubber, fluorine rubber, urethane rubber, chloroprene rubber, acrylic rubber, butyl rubber, etc. Those made of rubber are preferable, and according to them, positioning and shock / vibration absorption / relaxation can be satisfactorily performed using elasticity, and the end surface 1a of the case 1 and the holding body 5 function as a waterproof packing. This is also advantageous in securing waterproofness between the two. Even when a plurality of granular, string-like, hook-shaped, etc. are arranged as the elastic body 6, those made of these rubbers may be used. Moreover, you may use various resin which has elasticity similarly to these rubber | gum.

  The thickness, thickness (width), length, and other dimensions of the elastic body 6 made of rubber or resin may be appropriately selected according to the characteristics of the rubber or resin and the size and specifications of the camera module 10. The cross-sectional shape of the elastic body 6 may be appropriately selected from various shapes such as a circular shape, an elliptical shape, and a rectangular shape. Further, the elastic body 6 is arranged between the end surface of the case 1 and the holding body 5 by holding the convex portion (flange portion) 2 of the case 1 with the frame-like member 4 and sandwiching it between the end surface 1 a and the holding body 5. In this case, the case 1 may be arranged in any way as long as it can be positioned so that the case 1 is not tilted to secure the position accuracy and can absorb and mitigate shock and vibration. In accordance with the shape of the end surface 1a, it is preferable that the end surface 1a is evenly arranged so that each part of the end surface 1a can absorb and relieve shock and vibration evenly. For example, with respect to the circular end surface 1a, the elastic body 6 is disposed at a position corresponding to the center of each side with respect to the square end surface 1a, or the elastic body 6 is disposed at positions corresponding to the four corners. In other words, it may be arranged such that it is arranged approximately evenly in three or four or more places in the circumferential direction, or may be arranged in other places. Further, by arranging a plurality of annular elastic bodies 6 side by side or by doubling them, the wiring hole 5a that is desired to be waterproof is positioned inside the elastic body 6 or between the double holes. It may be.

  The elastic body 6 may be a spring such as a coil spring or a leaf spring. In the case where the elastic body 6 is a spring, a plurality of the elastic bodies 6 are arranged approximately evenly, and the waterproofness cannot be ensured by the elastic body 6, but the degree of elasticity is adjusted compared to rubber, resin, or the like. It is relatively easy to maintain elasticity stably over a long period of time.

  In any case of the elastic body 6, the repulsive force in a state where the elastic body 6 is sandwiched between the end surface 1 a of the case 1 and the holding body 5 and pressed by the frame-like member 4 is the case 1. Therefore, it is usually preferable to arrange them in a balanced manner with the center of gravity of the end surface 1a corresponding to the center of gravity of the case 1 as the center.

  In the case where a plurality of elastic bodies 6 are arranged and the input direction of the impact is limited in advance, the elastic body 6 may be arranged with priority in the direction of receiving the impact. Absorption / relaxation effects for specific impacts can be obtained.

  Next, FIG. 3A is an exploded perspective view showing another example of the embodiment of the camera module of the present invention, and FIG. 3B is a perspective view showing the assembled state. 4A is a plan view of the camera module main body of the example shown in FIG. 3 as viewed from the front side, and FIG. 4B is a cross-sectional view taken along the line AA shown in FIG. FIG. 4C is a cross-sectional view of the main part in the cross section taken along the line C-C shown in FIG. In the cross-sectional views of FIGS. 4B and 4C, the case 1 is shown in a side view with the cross-section omitted. In FIGS. 3 and 3, the same parts as those in FIGS. 1 and 2 are denoted by the same reference numerals.

  The basic configuration of the camera module 20 of this example is the same as that of the camera module 10 shown in FIGS. 1 and 2, but the guide 1 is used instead of the guide rail mechanism for positioning the case 1 and the frame-like member 4. A pin mechanism is adopted. That is, the convex portion 2 around the rear end portion of the case 1 having a quadrangular outer periphery is formed as a square flange portion 2 projecting around the end surface 1a, and the guide pins 2c are located at diagonal positions of the flange portion 2, respectively. Projecting toward the front side, the frame-like member 4 is provided with a corresponding pin hole 4c, and the frame-like member 4 is attached to the holding body 5 with the guide pin 2c passing through the pin hole 4c. .

  Even when such a guide pin 2c is used, the positional accuracy of assembly and attachment can be secured easily and satisfactorily. When an impact or vibration is applied from the outside, the case 1 is elastic along the guide pin 2c. Since it can move in the direction in which the body 6 is pressed, the impact and vibration absorption / relaxation effects of the elastic body 6 are not disturbed. Also, if the guide pins 2c are arranged in a non-symmetrical manner rather than symmetrically in the flange portion 2, there is no mistake in the direction in the direction around the optical axis when the case 1 is attached. It will be easy to do.

  And since the in-vehicle camera of the present invention is the camera module of the present invention attached to the vehicle via the holding body, the camera module absorbs and reduces the shock and vibration accompanying the movement of the vehicle, Since it becomes possible to prevent the breakage of the structural members including the lens, it becomes a highly reliable on-board camera having excellent durability. In this case, the holding body may be one assembled as a camera module and attached to the installation position of the vehicle, or may be one using the installation position of the vehicle as the holding body. For example, when the installation position of the camera module is the front grille of the vehicle, the camera module may be assembled using a bracket as a holding body, and the bracket may be attached to the front grille. The installation position may be set as a structure of the holding body, and a case may be disposed through the elastic body so that the convex portion of the case is pressed by the frame-shaped member.
