Detailed Description
The embodiment of the utility model discloses a structure for conveniently and manually adjusting the position of an image sensor of a camera, which comprises the following components as shown in figures 1-3:
the lens comprises a lens body 5, wherein the top of the lens body 5 is fixedly connected with a bottom plate 4, the top of the bottom plate 4 is slidably connected with a sliding support 1, one side of the sliding support 1 is provided with a torsion spring 3, the other side of the sliding support 1 is provided with a distance adjusting screw 2, and the top of the sliding support 1 is fixedly connected with a guide slope block 101;
the sensor comprises a sensor support 6, wherein bolts 8 are arranged at four corners of the sensor support 6, the sensor support 6 is fixed on a bottom plate 4 through the bolts 8, a compression spring 9 is sleeved on each bolt 8, a guide inclined plane groove 601 is formed in the bottom of the sensor support 6, and the guide inclined plane groove 601 is in contact with a guide inclined plane block 101;
and the image sensor 7, wherein the image sensor 7 is arranged on the top of the sensor bracket 6.
The top of compression spring 9 offsets with the nut of bolt 8, and the bottom of compression spring 9 offsets with the top of sensor support 6, and compression spring 9 is in compression state, is equipped with the sleeve in the four corners department of sensor support 6, and at the top fixedly connected with of bottom plate 4 and the location guide pillar that the sleeve corresponds, this location guide pillar activity is pegged graft in the sleeve, and sensor support 6 can be the up-and-down sliding motion on the location guide pillar.
The working principle is as follows:
as shown in fig. 1, a lens body 5 and a bottom plate 4 are fixed, a sliding support 1 can slide left and right on the bottom plate 4, two torsion springs 3 are installed at the left end of the sliding support 1, and the sliding support 1 slides towards the right end under the pressure of the torsion springs 3; the right end of the sliding support 1 is synchronously provided with the distance adjusting screw 2 which can effectively support and offset the elastic force from the torsion spring 3, and when the screwdriver is used for adjusting the locking depth of the distance adjusting screw 2, the sliding support 1 can easily slide left and right on the bottom plate 4.
Referring to fig. 2, fig. 2 is a complete assembly of the parts required in the present embodiment, in which the sensor bracket 6 and the image sensor 7 are fixed together by screws, and the sensor bracket 6 and the base plate 4 perform vertical lifting movement by the positioning guide posts, that is: when the sensor support 6 and the bottom plate 4 perform vertical lifting movement, the image sensor 7 can also vertically lift and lower together. The bolts 8 are synchronously arranged and locked on the bottom plate 4, the screws of the bolts 8 are sleeved with compression springs 9, and when the sensor bracket 6 ascends, the elasticity of the compression springs 9 is increased; when the sensor holder 6 descends to the bottom, the spring force received from the compression spring 9 becomes small.
Referring to fig. 3, which is a cross-sectional view of the actual operation state of the embodiment shown in fig. 3, it can be seen from the sectional view that a guide slope is designed at the contact surface between the sliding bracket 1 and the sensor bracket 6, and the guide slope is composed of a guide slope block 101 and a guide slope groove 601, which are pressed by the elastic force of the compression spring 9. When the distance adjusting screw 2 is locked to be deep, the distance adjusting screw pushes the sliding support 1 to move leftwards, the bearing gradient of the guide inclined plane moves downwards, and the sensor support 6 descends under the pressure of the elastic force of the compression spring 9; when the distance adjusting screw 2 is locked to be shallow, the elastic force from the torsion spring 3 can push the sliding support 1 to move rightwards, and at the moment, the bearing gradient of the guide inclined plane moves upwards to drive the sensor support 6 to ascend.
In summary, it can be seen that: in the embodiment, the rising and falling position adjustment of the sensor bracket 6 can be realized only by adjusting the locking depth of the distance adjusting screw 2 through a screwdriver; the sensor bracket 6 and the image sensor 7 are fixed into a whole through screws, namely, the locking depth of the distance adjusting screw 2 is adjusted, so that the position of the image sensor 7 can be adjusted to be raised and lowered. Therefore, the position of the image sensor 7 can be flexibly adjusted in a large range, the image sensor can be completely superposed with the image surfaces of a plurality of lenses on the market, and the image effect of the camera is clearer and higher in quality.
