Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
To facilitate understanding of the structure, the following structure of the fixed dual camera in fig. 1 to 5 is illustrated as a structure of the fixed dual camera applied to VR glasses in a Virtual Reality (VR) device.
Fig. 1 shows a schematic structural diagram of a fixed dual camera to which an embodiment of the present invention is applied. As shown in fig. 1, the structure of the fixed dual camera includes: a first camera 101; a second camera 102; the bracket 103 is fixedly connected with the first camera 101 and the second camera 102, and the bracket 103 comprises N holes; the N is an integer greater than or equal to 1; regarding the N holes, fig. 1 illustrates two holes 103a and 103b as examples; the buffer structure comprises N buffer sleeves, wherein the buffer sleeves are positioned in one hole for each buffer sleeve in the N buffer sleeves, and the N holes are in one-to-one correspondence with the N buffer sleeves; namely, fig. 1 illustrates 2 buffer jackets 104a and 104b as an example, a housing 105 and a connecting member 106, wherein the housing 105 and the bracket 103 are fixedly connected through N connecting members 106, namely, two connecting members 106 and 106a are illustrated as an example in fig. 1; for each of the N connecting pieces, the connecting piece penetrates through the buffer sleeve of one hole and is fixedly connected with the shell, and the N connecting pieces are in one-to-one correspondence with the N holes.
Because in the embodiment of the invention, each buffer sleeve in the N buffer sleeves is positioned in one hole of the bracket, and the connecting piece penetrates through the buffer sleeve in one hole to be fixedly connected with the shell; namely, flexible connection is realized between the bracket and the shell through the buffer structure. When the shell receives impact force, the force cannot be directly transmitted to the support, the force is required to be transmitted to the support after being buffered by the buffer structure, and the force transmitted to the support can be obviously weakened and even the support is not stressed due to the buffering of the buffer structure. Therefore, the structure for fixing the double cameras is beneficial to avoiding the influence on the bracket and the first camera and the second camera fixed on the bracket when the shell is impacted. Further, because the support is fixed on the casing through the connecting piece, namely the portion that support and casing contacted is only the portion that contacts with the connecting piece, the area of contact is little, and buffer structure's cushion collar is located the portion that support and connecting piece contacted, therefore, the transmission to the support when the casing atress is little, so, can further reduce the influence of casing atress to the support with first camera, second camera and fixed connection and first camera, second camera.
In the embodiment of the invention, the shell is fixedly connected with the bracket through N connecting pieces; among them, there are various implementations of the fixed connection.
Implementation one
One end of the connecting piece is fixed with the shell in a welding or gluing mode, and a buffer sleeve of the buffer structure is sleeved on the connecting piece at the contact part of the connecting piece and the bracket.
Implementation II
Fig. 2 shows a schematic structural diagram of a housing and a bracket fixedly connected by N connectors, to which the embodiment of the present invention is applied. Regarding N, fig. 2 illustrates N as 2; as shown in fig. 2, the bracket 103 includes two holes 103a and 103b; the housing 105 includes two fixing holes (not shown in fig. 2); the buffer structure comprises 2 buffer sleeves 104a and 104b; the two holes 103a and 103b on the bracket are in one-to-one correspondence with the fixing holes on the shell; the connecting piece 106 penetrates through the hole 103a and the buffer sleeve 104a on the bracket to be fixedly connected with the fixing hole on the shell, and the connecting piece 106 penetrates through the hole 103b and the buffer sleeve 104b to be fixedly connected with the fixing hole on the shell.
In the embodiment of the invention, the two holes are arranged on the bracket and the shell, so that the rotation of the bracket and the buffer structure can be avoided on one hand, and the contact area between the connecting piece and the bracket can be reduced on the other hand. The connecting piece runs through the hole on the support and the buffer sleeve on the buffer structure is fixed with the shell, so that the shell is flexibly connected with the support. When the shell is impacted, the force is not directly transmitted to the bracket, and the force needs to be buffered by the buffer structure and then transmitted to the bracket. The force transmitted to the bracket is obviously weakened, even the bracket is not stressed due to the buffering of the buffering structure.
Fig. 3 shows a schematic structural diagram of a positional relationship between a first camera, a second camera and a bracket, to which the embodiment of the present invention is applied. As shown in fig. 3, the first camera 101 and the second camera 102 are located at two ends of the bracket 103; the holes in the bracket are located in the middle of the bracket, and fig. 3 is illustrated with two holes 103a and 103 b.
In the embodiment of the invention, when the shell is impacted, the residual force after passing through the buffer sleeve of the buffer structure is transmitted to the bracket, and the position where the bracket is stressed only has the position overlapped with the connecting piece. Because the hole on the support is arranged in the middle of the support, the contact position of the connecting piece and the support is in the middle of the support, when the connecting piece transmits force to the middle of the support through the buffer structure, the rest force after buffering by the buffer structure is transmitted to the two ends on the support, the transmission path of the support to the two ends is far, and the transmission process consumes a lot of force. Thus, when the shell is impacted, the first camera and the second camera are not influenced basically; therefore, the fixed double-camera structure can better protect the first camera and the second camera, and further the double-camera can obtain a shot image more accurately.
Optionally, the material of the bracket comprises aluminum magnesium alloy. Because the strength of aluminum magnesium alloy is high, use aluminum magnesium alloy as the support of first camera and second camera be difficult for yielding, be favorable to fixing the stability and the durability of two camera structures. Optionally, the support of first camera and second camera is formed through computer numerical control lathe (Computer Numerical Control, abbreviated as CNC) processing, is used for fixing the plane at first camera and second camera both ends especially on the support, requires two planes to be on same horizontal plane, uses CNC processing technology to process this support, and the precision of processing is high, can satisfy two planes of fixed first camera and second camera on same horizontal plane, and the quality of the support that the processing obtained is reliable moreover.
Fig. 4 shows a schematic structural diagram of a buffer structure to which an embodiment of the present invention is applied. As shown in fig. 4, the buffer structure 104 includes a base pad 104c thereon; the N buffer sleeves are positioned on the base pad; FIG. 4 illustrates two buffer jackets 104a and 104b; the base pad is located between the housing and the bracket.
The embodiment of the invention provides an alternative implementation mode that a buffer sleeve of a buffer structure is assembled in a hole of a support, the inner diameter of the hole of the support is matched with the outer diameter of the buffer sleeve, and the buffer sleeve is assembled in the hole of the support. Optionally, the inner diameter of the buffer sleeve is matched with the diameter of the connecting piece, so that the connecting piece penetrates through the buffer sleeve. Alternatively, the cross section of the hole of the bracket and the buffer sleeve can be round or any other shape, and the hole of the bracket and the buffer sleeve are required to be arranged at the overlapped part of the shell and the buffer structure.
Optionally, the material of the buffer structure includes silica gel or rubber. The hardness of rubber or silica gel is less than the hardness threshold, so that the support and the shell are in flexible connection, the flexible connection can buffer the impact force transmitted by the shell, and when the shell is impacted, the optical parameters, positions and the like of the first camera and the second camera are not affected.
In the embodiment of the invention, the size of the buffer structure is smaller as much as possible, so that the contact area of the buffer structure and the support is smaller, the force transmitted to the support is smaller, and the influence on the support, the first camera and the second camera when the shell is impacted by the impact force is further reduced. Under the condition that design is met, the thicker the thickness of the base cushion in the buffer structure is, the more obvious the buffer effect on force is, the smaller the force transmitted to the support is, and the smaller the influence of the shell stress on the support, the first camera and the second camera is. Optionally, the N cushion covers and the base pad include an integral structure, and the material of the cushion cover and the base pad is the same. When the buffer sleeve is assembled in the hole of the bracket, flexible connection between the bracket and the connecting piece can be realized, and the buffer sleeve in the buffer structure can greatly reduce the force transmitted to the bracket. In addition, the buffer sleeve is arranged and assembled in the hole of the support, so that the space for fixing the buffer structure can be saved, the buffer structure and the support are tightly connected, and the stability of the double-camera structure can be improved.
Each of the N connectors in the embodiment of the invention comprises a screw with a gasket, wherein the screw comprises a nut and a stud; the fixing hole on the shell comprises a threaded hole; the nut is positioned on the bracket; the stud penetrates through a hole in the support and a buffer sleeve of the buffer structure to be fixed with a threaded hole in the shell. The bracket is fixed on the shell by the screw with the gasket, so that the bracket can be fixed on one hand, the other hand has the shockproof function by the screw with the gasket, the force transmitted to the bracket is further reduced, and the bracket is fixed by the screw in the process, so that the cost is lower.
In order to more clearly describe the structure of the fixed dual camera, fig. 5 shows a schematic diagram of another structure of the fixed dual camera to which the embodiment of the present invention is applied, where N is illustrated as 2 in the embodiment of the present invention; as shown in fig. 5, the structure for fixing the dual camera includes a first camera 101 and the second camera 102, a bracket 103, and two holes 103a and 103b on the bracket 103; the cushioning structure includes cushioning sleeves 104a, 104b and a base pad 104c located between the housing and the bracket; a housing 105 having two threaded holes 108; the connecting piece in the embodiment of the invention is a screw with a gasket, and the screw comprises a gasket 107a, a nut 107b and a stud 107c; the shell 105 is fixedly connected with the bracket 103 through a screw; the screw penetrates through the hole in the bracket and the buffer sleeve to be fixedly connected with the fixing hole in the shell, after the assembly is completed, the nut and the gasket of the screw are arranged on the bracket, and the stud penetrates through the hole in the bracket and the buffer sleeve and is connected with the fixing hole.
In the embodiment of the invention, the buffer sleeve is positioned in the hole of the bracket, and the screw through hole and the buffer sleeve are fixedly connected with the shell; namely, the support and the shell are flexibly connected through the base pad of the buffer structure, the support and the screw are flexibly connected through the buffer sleeve of the buffer structure, when the shell receives impact force, the force cannot be directly transmitted to the support, and the force is required to be transmitted to the support after being buffered through the base pad of the buffer structure and the buffer sleeve. The force transmitted to the bracket is obviously weakened, even the bracket is not stressed due to the buffering of the buffering structure. Therefore, the structure of the fixed double cameras helps to avoid the influence on the support fixedly connected with the first camera and the second camera when the shell is subjected to impact force. Further, because the support is fixed on the shell through the screw, namely the contact part of the support and the shell is only the contact part with the screw, the contact area is small, and therefore the force transferred to the support when the shell is stressed is smaller, the influence of the shell stress on the support fixedly connected with the first camera, the second camera and the first camera and the second camera can be further reduced.
The terminal in the embodiment of the invention comprises Virtual Reality (VR) equipment or augmented reality (Augmented Reality, AR for short) equipment. The VR equipment comprises VR glasses, VR head covers and the like; AR devices include head mounted displays and the like; the fixed double-camera structure is also applied to terminals with fixed double-camera structures, such as unmanned aerial vehicles, aircrafts and the like, which are provided with advanced driving assistance systems (Advanced Driver Assistant Systems, abbreviated as ADAS). The fixed dual camera structure applied to the terminal is not described in detail in the present embodiment, and reference may be made to the structures provided in fig. 1 to 5.
The points to be described are: the above description of the structure of the needle-fixed dual camera is merely exemplary and explanatory and is not intended to limit the present invention.
From the above, it can be seen that: in the embodiment of the invention, the buffer sleeve is positioned in the hole of the bracket, and the connecting piece penetrates through the hole of the bracket and the buffer sleeve to be fixedly connected with the shell; namely, flexible connection is realized between the support and the shell through the buffer structure, when the shell receives impact force, the force is not directly transmitted to the support, and is transmitted to the support after being buffered through the buffer structure. Therefore, the structure of the fixed double cameras helps to avoid the influence on the support fixedly connected with the first camera and the second camera when the shell is subjected to impact force. Further, because the support is fixed on the shell through the connecting piece, namely the contact part of the support and the shell is only the contact part with the connecting piece, the contact area is small, and therefore the force transferred to the support when the shell is stressed is smaller, and the influence of the shell stress on the support fixedly connected with the first camera and the second camera can be further reduced.
