[0034] Example:

[0035] See also Figures 1 to 3 The multi-lens camera in the preferred embodiment of the utility model comprises a housing 1, wherein an installation space is formed inside the housing 1, and a partition plate 15 is provided inside the housing 1, wherein the partition plate 15 divides the housing 1 into a first installation part and a second installation part. The first installation part is provided with a control mainboard 12, and a heat dissipation hole is provided on at least one side wall of the first installation part; the second installation part is provided with a sensor assembly and a plurality of lens assemblies 9, wherein the lenses of the plurality of lens assemblies 9 pass through the side wall of the second installation part and extend to the outside, and the sensor assembly is optically connected to the plurality of lens assemblies 9, and the sensor assembly is electrically connected to the control mainboard 12 at the same time.

[0036] The present application divides the housing 1 into two independent spaces by arranging a partition plate 15 inside the multi-lens camera, placing the control mainboard 12 alone in one space, and placing multiple lens assemblies 9 and sensor assemblies in the second mounting portion, so that the control mainboard 12, which is the main heating element, works alone in one space, and heat dissipation holes are opened on the side wall of the first mounting portion to ensure that the control mainboard 12 works efficiently and smoothly; secondly, the lens assembly 9 and the sensor assembly are enclosed in the second mounting portion, which prevents external dust or water vapor from entering the second mounting portion, and can prevent the control mainboard 12 from generating heat and affecting the sensor assembly when working, so as to ensure the stable operation of the lens assembly 9 and the sensor assembly.

[0037] Preferably, the sensor assembly and the control mainboard 12 in the present application are connected mainly by wire, so it is necessary to open corresponding through holes on the partition plate 15 for the corresponding cables or optical fibers to pass through, so as to realize the electrical connection between the sensor assembly and the control mainboard 12. Correspondingly, after the cables or optical fibers pass through the partition plate 15 of the present application, the through holes need to be sealed to avoid mutual influence between the components of the first mounting portion and the second mounting portion.

[0038] Further, as a preferred embodiment of the utility model, the partition plate 15 in the present application is against one of the side walls of the shell 1, and a support plate 20 is arranged between the partition plate 15 and the side wall of the shell 1, and the support plate 20 forms a triangular support structure with the partition plate 15 and the side wall of the shell 1. The partition plate 15 in the present application can be an integral structure with the shell 1, or it can be a split setting form. When the partition plate 15 is installed in the shell 1, in order to avoid the partition plate 15 from loosening in the shell 1, causing the first mounting part to be connected to the second mounting part, the present application corresponds to setting a support plate 20 inside the shell 1, and forming a triangular support structure by the support plate 20, the partition plate 15 and the side wall of the shell 1, so as to stably set the partition plate 15 inside the shell 1. Optionally, the support plate 20 here can be arranged in the first mounting part or the second mounting part, as long as it can support the partition plate 15. Preferably, the support plates 20 in the present application are arranged in pairs, and the two support plates 20 are respectively supported at both ends of the partition plate 15 along the length direction.

[0039] Further preferably, the support plate 20 in the present application is arranged in the second mounting portion, and a desiccant 16 is placed in the triangular support structure formed by the support plate 20, the partition plate 15 and the side wall of the housing 1. The first mounting portion in the present application is mainly used to place the control mainboard 12. The space of the first mounting portion is smaller than the space of the second mounting portion. It is more convenient to arrange the support plate 20 in the second mounting portion. At the same time, the triangular support structure formed by the support plate 20, the partition plate 15 and the side wall of the housing 1 can also be used to place the desiccant 16, so as to further ensure the dryness of the working space of the lens assembly 9 and the sensor assembly. Optionally, the desiccant 16 is placed in a bag or a placement box to prevent the desiccant 16 from scattering.

[0040] Furthermore, as a preferred embodiment of the utility model, a fixed bracket 18 is further provided in the second mounting portion in the present application, and a plurality of harness holes are arranged on the fixed bracket 18. A plurality of lens assemblies 9 are connected to the sensor assembly through optical fibers, and the optical fibers of each lens assembly 9 are connected to the sensor assembly after passing through each harness hole in turn. Since the present application is a multi-lens camera, each lens assembly 9 needs to be connected to the sensor assembly through an optical fiber to achieve corresponding data transmission. In order to avoid the optical fibers of each lens assembly 9 being arranged in a disorderly manner inside the housing 1, which is inconvenient for later opening and repairing of the multi-lens camera, the present application correspondingly sets a fixed bracket 18, and opens a plurality of harness holes on the fixed bracket 18, so as to constrain each optical fiber separately, facilitate the identification and replacement of each optical fiber, and facilitate the arrangement and installation of various components inside the multi-lens camera.

[0041] Preferably, the fixing bracket 18 in the present application is a plate-like structure as a whole, which is fixed to the side wall of the shell 1 through the pins 11 and the flange 10, and a certain space is left between the fixing bracket 18 and the side wall of the shell 1 for the optical fiber to pass through.

[0042] Further, as a preferred embodiment of the utility model, the housing 1 in the present application is formed with an arc-shaped concave surface at the installation position of multiple lens assemblies 9, and each lens assembly 9 is distributed in a fan shape on the arc-shaped concave surface; at the same time, the fixed bracket 18 is composed of multiple fan plate assemblies, and the multiple fan plates are arranged concentrically with the multiple lens assemblies 9. The multi-lens camera in the present application mainly detects a single precision device, and the optical path of each lens assembly 9 is in a convergent state. Therefore, the present application forms an arc-shaped concave surface on the housing 1, and arranges multiple lens assemblies 9 on the arc-shaped concave surface to form a convergent posture. Correspondingly, the present application sets the fixed bracket 18 to be formed by a fan plate, and the fan plate is arranged concentrically with the lens assembly 9, so that the optical fiber connected to each lens assembly 9 is almost equidistantly connected to the fan plate, which facilitates the connection of each lens assembly 9 with the sensor assembly. The structure of the fixed bracket 18 being set as multiple fan plates facilitates the manufacture of the fixed bracket 18 itself, and when it is necessary to replace the optical fiber or disassemble the fixed bracket 18, the corresponding part of the fan plate can be disassembled to reduce maintenance work.

[0043] Furthermore, as a preferred embodiment of the utility model, the sensing assembly in the present application includes a sensor 17 and a signal acquisition board 19, and the sensor 17 and the signal acquisition board 19 are both arranged at the corners of the second mounting portion, and the sensor 17 and the signal acquisition board 19 are arranged along the tangent direction of the fixed bracket 18. Specifically, the sensor 17 is mainly used to receive the optical signal transmitted from the lens assembly 9, and the signal acquisition board 19 is mainly used to receive the information transmitted by the sensor 17, and convert it into an electrical signal that can be received by the control main board 12, and finally the signal is converted into other visual images or information through the control main board 12 or an external device. Since the fixed bracket 18 in the present application is a fan plate structure, the fixed bracket 18 and the lens assembly 9 occupy most of the space of the second mounting portion. In order to facilitate the arrangement of the sensor 17 and the signal acquisition board 19 in the second mounting portion, interference with the fixed bracket 18 is avoided.

[0044] Further, as a preferred embodiment of the utility model, the housing 1 in the present application is provided with a first side wall 4 and a second side wall 2, wherein the first side wall 4 is located on the first mounting portion, the second side wall 2 is located on the second mounting portion, and the first side wall 4 and the second side wall 2 are both detachably connected to the housing 1. The first side wall 4 and the second side wall 2 are both detachably connected to the housing 1, so that the first mounting portion and the second mounting portion can be opened correspondingly, so as to facilitate the installation of the above-mentioned control mainboard 12, sensor assembly and lens assembly 9 into the housing 1, so as to realize the disassembly and assembly of various components in the multi-lens camera.

[0045] Furthermore, as a preferred embodiment of the utility model, a heat sink 14 is also provided in the first mounting portion in the present application, and the heat sink 14 is attached to the surface of the control main board 12, and a radiator 13 is correspondingly provided on the side of the heat sink 14 facing away from the control main board 12; at the same time, the heat dissipation holes in the present application include a first heat dissipation hole 8 and a second heat dissipation hole 3, wherein the first heat dissipation hole 8 is arranged toward the air outlet of the radiator 13, for discharging the heat generated by the control main board 12; the second heat dissipation hole 3 is arranged toward the air inlet of the radiator 13, for sucking in external air to exchange heat with the control main board 12.
