It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 8, an embodiment of the present invention discloses a multi-view camera, which includes a lens adjusting device, a main chassis assembly 400, a transparent cover 500, and a lens 300.

The transparent cover 500 is mounted on the main chassis assembly 400, and the lens adjusting device is mounted in a space formed by the transparent cover 500 and the main chassis assembly 400. The transparent cover 500 is generally fixed to the main chassis assembly 400 in a fixed manner. The transparent cover 500 includes a planar portion 510 and a curved portion 520 surrounding the planar portion 510. In one specific embodiment, the planar portion 510 is located at the center of the transparent cover 500, and the curved portions 520 are distributed around the planar portion 510.

The movement of the first bracket 210 drives the lens 300 to move along with the movement, so that the position of the lens 300 on the fixed tray 100 can be adjusted, and finally the P-direction adjustment of the lens 300 is realized, so that the lens 300 moves in a plane parallel to the fixed tray 100.

In the multi-view camera disclosed in the embodiment of the present application, the transparent cover 500 is mounted on the main housing assembly 400, the transparent cover 500 includes the planar portion 510 and the curved portion 520, the curved portion 520 is disposed around the planar portion 510, and the lens 300 is mounted in the space covered by the curved portion 520, which can improve the deformation resistance of the transparent cover 500. Meanwhile, in the lens adjusting apparatus, the lens holder 200 includes a first holder 210, and the first holder 210 can drive the lens 300 to move along the circumferential direction of the fixed tray 100, thereby realizing the P-direction adjustment of the lens 300. After the lens 300 is adjusted in place, only the lens holder 200 needs to be positioned, and the entire fixed disk (equivalent to the mounting disk in the background art) does not need to be locked by a magnet.

In a specific embodiment, one of the first bracket 210 and the fixed tray 100 may be provided with a first tooth groove, and the other may be provided with a first engaging tooth, and the first tooth groove is engaged with the first engaging tooth. The first bracket 210 is coupled to the fixed platter 100 by engaging the first teeth grooves with the first engaging teeth.

In the lens adjusting device disclosed in the embodiment of the present invention, the lens 300 is mounted on the first bracket 210, and then can move on the fixed disk 100 along with the first bracket 210, thereby realizing the adjustment of the position of the lens 300 on the fixed disk 100. The first bracket 210 is connected with the fixed tray 100 by the engagement between the first tooth grooves and the first engaging teeth, in the adjustment process, an operator can drive the first bracket 210 to move by applying a certain force, in the movement process of the first bracket 210, the first tooth grooves and the first engaging teeth move relatively, and after the adjustment is finished (the external force is removed), the engagement between the first tooth grooves and the first engaging teeth can ensure that the first bracket 210 is positioned at the adjusted position, and finally the adjustment of the lens 300 is completed.

Compared with the mode of fixing the lens through the magnet in the prior art, the lens adjusting device disclosed by the invention does not need the magnet with a larger volume, so that the lens adjusting device disclosed by the invention can also solve the problems of larger mass and higher cost in the mode of locking the lens by the magnet in the existing multi-view camera.

In a specific embodiment, the circular edge of the fixed plate 100 is partially or entirely provided with the first teeth groove 110, and correspondingly, the first bracket 210 is provided with the first engagement teeth 211 a. The first bracket 210 is movable in a circumferential direction of the fixed platter 100 and thus can rotate in the circumferential direction of the fixed platter 100. The rotation of the first bracket 210 drives the lens 300 to rotate, so as to adjust the position of the lens 300 on the fixing plate 100. This position adjustment is performed in a plane parallel to the surface of the fixed platter 100, which is a P-direction adjustment of the lens 300. Of course, the first tooth grooves 110 may be provided on the first bracket 210, and correspondingly, the first engagement teeth 211a are provided on the fixed platter 100.

The first bracket 210 may include an elastic connection part 211, and the elastic connection part 211 may be provided with a first engagement tooth 211a, the first engagement tooth 211a being engaged with the first slot 110. In the embodiment of the present invention, the engagement between the first tooth groove and the first engaging tooth means that the first tooth groove and the second engaging tooth are in a positioning state when they are not subjected to an external force, and the first tooth groove and the second engaging tooth cannot move relatively; when the first tooth groove or the first engaging tooth is elastically deformed by an external force, the positioning engagement between the first tooth groove and the first engaging tooth is released, so that the first tooth groove and the second engaging tooth can move relatively, and further the first bracket 210 can move around the circumferential direction of the fixed disk 100, that is, the first bracket 210 rotates along the circumferential direction of the fixed disk 100.

The elastic connection portion 211 ensures that the first tooth space 110 and the first tooth space 211a are engaged with each other with good elasticity through elasticity of the elastic connection portion 211, and the elastic connection portion 211 is elastically deformed under the action of external force, so that the first tooth space 211a and the first tooth space 110 are positioned and removed, and relative rotation between the first tooth space 211a and the first tooth space 110 can be achieved.

There are various ways to realize the rotation of the first bracket 210 around the circumferential direction of the fixed disk 100, the first bracket 210 may roll along the circumferential direction of the fixed disk 100 through the rolling bodies to realize the rotation thereof, and the first bracket 210 may also slide along the circumferential direction of the fixed disk 100 to realize the rotation thereof.

The first bracket 210 is positioned and matched with the annular slide rail in a direction perpendicular to the disk surface of the fixed disk, which means that the first bracket 210 cannot move relative to the fixed disk 100 in a direction perpendicular to the disk surface but can only move along the circumferential direction of the fixed disk 100, thereby realizing rotation. Herein, the positioning engagement of the first bracket 210 with the annular slide in a direction perpendicular to the disk surface of the fixed disk 100 means that the first bracket 210 cannot move relative to the fixed disk 100 in a direction perpendicular to the disk surface of the fixed disk 100.

There are various ways of forming the circular slide on the stationary platter 100, for example, the circular slide is formed on the surface of the platter 100. Referring to fig. 1 again, the center of the fixing plate 100 is provided with an avoiding hole 120, and in particular, the avoiding hole 120 may penetrate through the fixing plate 100. The provision of the escape hole 120 enables the entire stationary platen 100 to be an annular structural member, and the first bracket 210 moves along the annular structural member, thereby enabling the first bracket 210 to rotate in the circumferential direction of the stationary platen 100.

Referring to fig. 3-5 again, the first bracket 210 may include a connection seat 212 and a first buckle 213, the connection seat 212 is attached to a surface of one side of the fixed tray 100, and the first buckle 213 is fixedly connected to the connection seat 212 and passes through the avoiding hole 120 to be buckled with the fixed tray 100. The coupling seat 212 and the first latch 213 are respectively engaged with surfaces of both sides of the fixed platter 100, enabling the first bracket 210 to be assembled on the fixed platter 100. In the first bracket 210, the connection holder 212 can slide with respect to a surface of one side of the fixed platter 100 during the rotation of the fixed platter 100 in the circumferential direction, and also the first catch 213 can slide with respect to a surface of the other side of the fixed platter 100.

The elastic connection portion 211 may be a part of the connection holder 212 or the first catch 213, or may be independent of the connection holder 212 and the first catch 213.

In a specific embodiment, the first bracket 210 may include a connection seat 212 and an elastic connection portion 211. The elastic connection portion 211 is a first elastic arm, one end of which is fixed on the connection seat 212, and the other end of which is a free end, and the free end of the first elastic arm can be located outside the circular edge of the fixed disk 100. The free end of the first elastic arm can elastically deform relative to the connecting seat 212, and then the first elastic arm is disengaged to realize the relative rotation between the first bracket 210 and the fixing plate 100.

In order to ensure that the first bracket 210 does not rotate when not subjected to an external force or a small interference force, it is preferable that at least one of the first bracket 210 and the fixing plate 100 is provided with a tightening portion capable of tightening and attaching to the other. Referring to fig. 3, the tensioning portion may include a first tensioning protrusion 212a and/or a second elastic arm 212 b.

Referring to fig. 2 again, in the embodiment of the present invention, there may be a plurality of lens holders 200, and a plurality of lens holders 200 may be distributed along the circumferential direction of the fixing plate 100. Specifically, a plurality of lens holders 200 may be dispersedly arranged along the circumferential direction of the fixed disk 100.

Referring to fig. 4, 6, 7 and 8, in the lens adjusting apparatus according to the embodiment of the present invention, the lens holder 200 includes a second holder 220, and the second holder 220 is disposed on the first holder 210. The second bracket 220 can be rotatably engaged with the lens 300, so that the lens rotates around its axis to adjust the lens 300, i.e. to adjust the lens 300 in the R direction.

The second bracket 220 is rotatably disposed on the first bracket 210 and can move in a direction perpendicular to the surface of the fixed disk 100, so that the second bracket 220 drives the lens 300 to rotate in a pitching manner, and finally the lens 300 is rotatably adjusted in a direction perpendicular to the surface of the fixed disk 100, i.e., in a T-direction.

To allow for more flexibility in adjustment, the first bracket 210 may include a support arm 214 that is rotationally coupled to a second bracket 220.
