Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.

As shown in fig. 1-3 and fig. 6-7, the 3D camera simulation debugging apparatus includes a support 10, a first Y-direction coarse adjustment mechanism 70, a laser mounting seat 50, a second Y-direction coarse adjustment mechanism 80, a camera mounting seat 90, and a detection platform 100; wherein the content of the first and second substances,

the first Y-coarse adjustment mechanism 70 includes a first sliding seat 71 and a first tightening structure 72; the first sliding seat 71 is arranged on the support 10 and can move along the Y direction relative to the support 10; the support 10 is provided with a first graduated scale 73 extending along the Y direction and positioned in the moving path of the first sliding seat 71; a first indication arrow 74 pointing to the scale is mounted on the first sliding seat 71; the first elastic structure 72 is used for locking the first sliding seat 71 on the support 10;

the laser mounting base 50 is fixed on the first sliding base 71 and is used for mounting the laser 60;

the second Y-coarse adjustment mechanism 80 includes a second sliding seat 81 and a second elastic structure 82; the second sliding seat 81 is mounted on the support 10 and can move along the Y direction relative to the support 10; the support 10 is provided with a second graduated scale 83 which extends along the Y direction and is positioned in the motion path of the second sliding seat 81; a second indication arrow 84 pointing to the second graduated scale 83 is mounted on the second sliding seat 81; the second elastic structure 82 is used for locking the second sliding seat 81 on the support 10;

the camera installation seat 90 is fixed on the second sliding seat 81 and is used for installing the camera module 210;

an inspection platform 100 is mounted on the support 10 and is positioned below the laser mount 50 and the camera mount 90.

On the basis of the structure, when the position of the laser 60 in the Y direction needs to be adjusted, reading the reading of the first graduated scale 73 indicated by the first indication arrow 74 at this time, the external force drives the first sliding seat 71 to move along the Y direction and is linked with the laser mounting seat 50 to move along the Y direction, after the first sliding seat 71 is fixed on the support 10 by adopting the first tightening structure 72, and reading the reading indicated by the first indication arrow 74 again, so that the movement displacement of the laser 60 on the laser mounting seat 50 in the Y direction can be obtained; when the position of the camera module 210 in the Y direction needs to be adjusted, reading the reading of the first graduated scale 73 indicated by the second indication arrow 84 at this time, driving the second sliding seat 81 to move along the Y direction by external force and linking the camera mounting seat 90 to move along the Y direction, fixing the second sliding seat 81 on the support 10 by using the second tightening structure 82 after the second sliding seat is in place, and reading the reading indicated by the second indication arrow 84 again, so that the movement displacement of the camera module 210 on the camera mounting seat 90 in the Y direction can be obtained; from the above, the relative positions of the laser 60 and the camera module 210 in the Y direction after the change can be known, thereby being suitable for various 3D camera designs.

After confirming the positional relationship between the laser 60 and the camera, the mechanical design engineer can quickly understand the positional structure parameters thereof, and then intuitively understand the requirements for the external dimensions and the internal installation structure of the housing when the housing design of the 3D camera is carried out, thereby reducing design errors and avoiding modification cost in the housing sample manufacturing process.

It should be noted that the above-mentioned camera module 210 can be a plane camera or a camera, as long as the image acquisition and transmission can be achieved.

Specifically, the first fastening structure 72 includes an abutting member 721, an abutting elastic member 722, a transmission assembly 723, a connecting rod 724 and a rotating handle 725; the abutting member 721 is mounted on the first sliding seat 71 and is movable with respect to the first sliding seat 71 between a position abutting against the support 10 and a position away from the support 10; when the abutting member 721 abuts against the support 10, the first sliding seat 71 can be prevented from moving relative to the support 10 under the action of the friction force between the abutting member 721 and the support 10; the abutting elastic member 722 is installed between the abutting member 721 and the first sliding seat 71 and is used for providing elastic stress for urging the abutting member 721 to abut against the support 10; the connecting rod 724 is fixed on the first sliding seat 71; the rotating handle 725 is rotatably arranged on the connecting rod 724 and is in transmission connection with the abutting member 721 through a transmission assembly 723; when the rotating handle 725 rotates, the pushing member 721 can be linked to be far away from the support 10 through the transmission assembly 723; in this way, in the process of rotating the rotation to move the abutting member 721 away from the support 10, the elastic stress of the abutting member 721 abutting against the support 10 is overcome by the abutting elastic member 722, i.e. the friction force between the abutting member 721 and the support 10 is released, so that the first sliding seat 71 can be moved; and, when the rotating handle 725 is released, the abutting member 721 abuts against the support 10 under the action of the abutting elastic member 722, at this time, the first sliding seat 71 is prevented from moving relative to the support 10 under the friction force between the abutting member 721 and the support 10, and simultaneously, the rotating handle 725 is reset under the action of the abutting member 721.

Since the position of the laser 60 is adjusted by a plurality of shifting operations, which cannot be performed at one time, it can be seen from the above structure that when the first sliding seat 71 needs to be moved, the first sliding seat 71 can be fixed only by rotating the rotating handle 725 and loosening the rotating handle 725, so that the operation is more convenient.

In order to ensure that the friction force is large enough to prevent the first sliding seat 71 from moving relative to the seat 10, the abutting member 721 is preferably made of a rubber material, and more preferably, the seat 10 includes a body of the seat 10 and a rubber pad fixed on the body of the seat 10, and the rubber pad is used for abutting against the abutting member 721. Specifically, the abutting member 721 is movably inserted into the first sliding seat 71 through the connecting shaft 726, that is, the abutting member 721 is fixedly connected to the connecting shaft 726, and the connecting shaft 726 is movably inserted into the first sliding seat 71; at this time, the connecting shaft 726 supports the first sliding seat 71, and it is understood that the connecting shaft 726 may be made of a strong material.

More specifically, the abutting elastic member 722 is an abutting spring, the abutting spring is sleeved on the connecting shaft 726, and two ends of the abutting spring abut against the abutting member 721 and the first sliding seat 71 respectively, so that the fastening of the abutting spring is realized, and the two ends of the abutting spring do not need to be fixed, thereby simplifying the installation procedure; of course, the elastic member 722 may also be a spring, an elastic column, etc.

Further, the transmission assembly 723 comprises a connecting member 7231, a rotating shaft 7232 fixed to an end of the connecting shaft 726 far away from the abutting member 721, and a first kidney-shaped groove 7233 formed in the connecting member 7231; the rotating shaft 7232 is movably inserted into the first waist-shaped groove 7233; one end of the connecting piece 7231 is hinged on the connecting rod 724, and the rotating handle 725 is fixed at the other end of the connecting piece 7231; thus, when the rotating handle 725 is rotated, the connecting element 7231 is rotated around the hinge point of the connecting element 7231 by the rotation, at this time, the groove wall of the second waist-shaped groove 243 of the connecting element 7231 pushes the rotating shaft 7232, and the rotating shaft 7232 drives the abutting element 721 to move through the connecting shaft 726; in the structure, the connecting piece 7231 and the rotating shaft 7232 are movably inserted and matched, so that the maintenance and the replacement are convenient.

In order to prevent the connecting member 7231 from being disengaged from the rotating shaft 7232 during use, preferably, the connecting member 7231 is provided with a receiving groove 727; the two opposite groove walls of the accommodating groove 727 are respectively provided with a first waist-shaped groove 7233; the number of the rotating shafts 7232 is two, and the two rotating shafts 7232 are respectively disposed on opposite sides of the coupling shaft 726 and are respectively and correspondingly inserted into the two first kidney-shaped grooves 7233, thereby fixing the coupling shaft 726 in the coupling member 7231.

On the basis of the above structure, since the first sliding seat 71 is fixed by friction of the abutting member 721 and the support 10, in order to further prevent the first sliding seat 71 from moving relative to the support 10, more specifically, a reinforcing structure 190 may be further provided, wherein the reinforcing structure 190 includes a rotation adjusting rod; the rotary adjusting rod is provided with a threaded section, and the threaded section is arranged in the first sliding seat 71 in a penetrating way and is in threaded fit with the first sliding seat 71; one end of the rotary adjusting rod facing the support 10 is formed into a propping end; the abutting end is used for being in frictional contact with the support 10 to prevent the first sliding seat 71 from moving relative to the support 10. When in use, after the final positioning of the first sliding seat 71 is completed, the abutting end abuts against the support 10 by rotating the rotary adjusting rod, so that the first sliding seat 71 can be further stabilized.
