Embodiment
Describe the slide block assembly be used for lens cap according to an embodiment of the invention and and digital camera in detail below with reference to accompanying drawing with this slide block assembly.
With reference to figure 1; digital camera 100 comprises camera body 110 and lens cap 120; wherein camera body 110 has front surface and is arranged in camera lens 111 on the front surface; lens cap 120 is attached to and is used for when using digital camera 100 exposure lens 111 on the front surface of camera body 110 with the shot object photo, and is used for len 111 when use digital camera 100.The slide block assembly 200 that is used for laterally slidably lens cap 120 being connected to camera body 110 is installed between camera body 110 and the lens cap 120.
Shown in Fig. 2 and 3, slide block assembly 200 comprises fixed head 220, be connected to the sliding panel 210 of fixed head 220 slidably, and remain on a pair of resilient bias unit 230 that is used for applying resilient bias power between fixed head 220 and the sliding panel 210 to sliding panel 210.
Fixed head 220 has a pair of isolated alar part 221 twice of its vertically opposite end bending, a pair of isolated first hinge of between alar part 221, arranging 222, and the guide plate part 223 that between first hinge 222, forms in glide direction (promptly at horizontal direction) extension.Between guide plate part 223 and one first hinge 222, be formed on the guide channel 224 that glide direction is extended.Edge along guide channel 224 forms with the outstanding limit (rim) of specified altitude assignment.
Illustrate as Fig. 3 the best, sliding panel 210 has a pair of isolated leader 211, is used to receive the alar part 221 of fixed head 220 and guides alar part 221 in glide direction.Crooked twice toward each other of each leader 221.In addition, fixed head 220 has a plurality of dummy rolls (idle roller) 214 that roll and contact with the relative horizontal surface of guide plate part 223, layout to be inserting dummy roll 214 on a pair of isolated second hinge 212 therebetween, and is inserted in and is used for the guidance axis 213 that moves along guide channel 224 in the guide channel 224.Guidance axis 213 can be fixed type or rolling type.In the present invention, guidance axis 213 and guide channel 224 switch each other.In other words, guidance axis 213 can be attached to fixed head 220, and guide channel 224 can be formed in the sliding panel 210 to extend in glide direction.
Each a pair of sliding part 215 that all has an alar part 221 of the correspondence that is used to guide fixed head 220 is installed to the leader 211 of sliding panel 210.Sliding part 215 is used to reduce because the friction slip between leader 211 and the alar part 221 contacts the wearing and tearing that cause, and it is mobile to allow alar part 221 smoothly to slide simultaneously.For this reason, sliding part 215 is made by the material of the dynamic friction coefficient of wearing quality with increase and reduction.
Refer again to Fig. 3, each resilient bias portion 230 all has first end 231 and second end 232, and is formed by the torsion-bar spring of zigzag bending.First end, 231 quilts of each resilient bias portion 230 partly center on and pivotally are connected to one second corresponding hinge 212, and second end 232 of each resilient bias portion 230 is partly centered on and pivotally be connected to one first hinge 222 of correspondence.Resilient bias portion 230 remains between sliding panel 210 and the fixed head 220 on glide direction sliding panel 210 being applied resilient bias power, thereby by resilient bias portion 230 sliding panel 210 that can semi-automatically slide.In the present invention, resilient bias portion 230 is not limited to described resilient bias portion, but can be changed to having other structure, as long as can be fixed to first hinge 222 and second hinge 212 and can on glide direction, apply resilient bias power to sliding panel 210.Because the modification for resilient bias portion 230 is significantly to those skilled in the art, modified example is not described in detail.
Next, the operation of slide block assembly 200 will be described with reference to figure 4 and Fig. 5.Fig. 4 shows lens cap 120 wherein and is closed state with the slide block assembly 200 of hiding camera lens 111, and Fig. 5 shows lens cap 120 wherein and is opened with the state of the slide block assembly 200 of exposure lens 111.Although not shown, fixed head 220 is fixedly connected to the front surface of camera body 110 by the securing member by for example screw etc.Similarly, sliding panel 210 is fixedly connected to the inside surface of lens cap 120 by screw or other securing member.
When lens cap 120 is closed, as shown in Figure 4, dummy roll 214 maintenances of sliding panel 210 and the relative horizontal surface contact of the guide plate part 223 of fixed head 220, and guidance axis 213 is inserted into guide channel 224.Therefore, the glide direction of sliding panel 210 is by guide channel 224 and 223 restrictions of guide plate part.
If the user is opening direction (among Fig. 4 left) zoom-up lid 120 opening lens cap 120 and to use digital camera 100, sliding panel 210 moves slidably opening direction.At this moment, second hinge 212 of sliding panel 210 moves together, and the result makes first end 231 of resilient bias portion 230 move and flexibly be out of shape in glide direction.The resilient bias power that applies to sliding panel 210 is in closing direction (among Fig. 5 to the right) effect, farthest compressed up to resilient bias portion 230, and if then sliding panel 210 move through the position that resilient bias portion 230 at utmost compressed then opening directive effect.Thereby under the effect of the elastic restoring force of resilient bias portion 230, sliding panel 210 automatically is moved to open position.In the slip of sliding panel 210 was moved, guidance axis 213 moved along guide channel 224, and dummy roll 214 with in the rolling contact on horizontal surface, the moving of guide plate part 223, this level and smooth slip that has guaranteed sliding panel 210 is moved.As a result, compare with the prior art lens cap, lens cap 120 can smoothly slide mobile.
The user is applying under the situation of external force lens cap 120 on the closing direction after using digital camera 100, and sliding panel 210 moves at closing direction, thus elasticity of compression offset portion 230.If sliding panel 210 moves through the position that resilient bias portion 230 is at utmost compressed, then under the effect of the elastic restoring force of resilient bias portion 230, sliding panel 210 and lens cap 120 are semi-automatically moved to off-position.
Fig. 6 shows the slide block assembly 200 that is used for lens cap in accordance with another embodiment of the present invention.The slide block assembly 200 of this embodiment is guide plate part 223 and its relational structure with the difference of slide block assembly 200 shown in Figure 3.Sliding panel 210 has the sliding channel portion 216 that engages slidably with the guide plate part 223 of fixed head 220.
Above embodiment only is shown for purposes of illustration, and thereby, the invention is not restricted to these embodiment.Those skilled in the art are to be understood that under the prerequisite that does not depart from the scope of the present invention that limits in the claim can carry out various changes and modification.
Industrial applicability
At the slide block assembly for lens cap of the present invention, adopted resilient bias section with can so that the user by opening and closing lens cap with the power that reduces. By this slide block assembly, also can greatly reduce the possible locking mobile and that cause of reversing of lens cap. This helps to improve convenience, reliability and the quality of the use of the product of having used slide block assembly of the present invention.
