Description

Technical Field

[0001] This utility model relates to the field of camera technology, and in particular to a module housing for mounting a camera, and also to a camera module formed using the module housing. Background Technology

[0002] Cameras are currently widely used in many fields such as autonomous driving, robot navigation, 3D reconstruction, and facial recognition / payment. They work in conjunction with other control and execution components to achieve intelligent and automated implementation of tasks. Based on binocular cameras, two cameras side by side capture the same scene from different angles simultaneously. By using the principle of parallax to calculate the depth information of objects, three-dimensional perception is achieved, which can greatly improve control accuracy and thus be more widely used.

[0003] Traditional binocular camera modules have their cameras exposed on the mounting surface, lacking protection and posing a high risk of impact. These cameras are also prone to positional deviations after being touched. Binocular cameras have extremely stringent requirements for the distance tolerance between the two lenses, which is crucial for ensuring precise control. If the camera is fully enclosed in a conventional casing, the internal circuit boards and components will generate heat during prolonged operation, which is difficult to dissipate effectively. Furthermore, some of the sensors are temperature-sensitive, and prolonged exposure to relatively high temperatures will also affect their detection accuracy. In addition, the limited mounting points for the current housings containing the camera and circuit boards restrict the flexibility of using binocular camera modules. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a module housing that can effectively encapsulate and protect the camera, dissipate heat in a timely manner, and is easy and flexible to install.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a module housing for encapsulating a binocular camera and its control and processing circuit, including a housing with an opening at one end, a base plate detachably mounted on the opening end of the housing, a housing mounting and fixing device on the housing, two transparent camera windows mounted opposite each other on the housing, and fixing studs for mounting and fixing circuit boards arranged inside the housing; the base plate has an outer groove protruding towards the outside of the housing and an inner groove protruding towards the inside of the housing, the outer groove is used to accommodate electrical components inside the housing, the inner groove is used to abut against the chip inside the housing and has a heat dissipation colloid on its surface, a data cable socket and an venting device are provided through the base plate, and a base plate mounting and fixing device is also arranged on the base plate and extends into the housing.

[0006] As a preferred technical solution, the housing mounting and fixing device includes an outer assembly ring platform that is arranged around and protrudes outward on the circumferential surface of the housing, and bolt mating parts are arranged on the outer assembly ring platform.

[0008] As a preferred technical solution, the venting device includes a screw hole that penetrates the base plate, a venting bolt that is threaded into the screw hole, a central venting hole that is coaxial with the stud of the venting bolt, and side venting holes that communicate with the central venting hole that are also provided on the stud of the venting bolt.

[0009] As a preferred technical solution, a protective enclosure is provided protrudingly on the outer surface of the base plate, located around the data cable socket and the venting device, respectively.

[0010] As a preferred technical solution, the two camera windows are detachably mounted on the housing.

[0011] As a preferred technical solution, the base plate mounting and fixing device includes a hollow column integrally formed with the base plate, and the hollow column extends into the housing. A mounting screw groove is provided coaxially with the hollow column, and the port of the mounting screw groove is arranged facing the outside of the base plate.

[0012] As an improvement to the above technical solution, the hollow columns are arranged opposite each other on the base plate, and a reinforcing rib is fixedly connected between the two hollow columns arranged opposite each other.

[0013] This utility model also relates to a camera module, including the above-mentioned module housing, with cameras respectively installed on the inner side of each of the camera windows, and a segmented PCB circuit board connected to the camera.

With the cooperation of the housing, base plate, and camera window, the components can be installed in a fully enclosed manner, which helps to protect the camera. Furthermore, the heat generated by the internal components during operation can be released to the outside through the venting device, and with the heat transfer effect of the heat dissipation colloid and the inner groove, it helps to keep the internal components working in a reasonable temperature environment, thereby ensuring the accuracy of signal detection and processing, and indirectly ensuring the precision of the camera module application system control.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0028] like Figures 1 to 7 As shown, the module housing is used to encapsulate the binocular camera and its control and processing circuitry, forming an integrated module for image acquisition and processing. This module can be installed in intelligent products such as drones and robots to facilitate precise control of mission functions. Specifically, this embodiment includes a housing 1 with an opening at one end, used to carry the camera 19 and its associated control and processing circuitry. A base plate 2 is detachably mounted to the opening end of the housing 1, encapsulating the camera 19 and all electronic components to form a complete and independent camera module product. The housing 1 has an inwardly protruding mounting ring, and the base plate 2 has an outwardly protruding mounting ring. Screw holes are provided through both mounting rings to allow for detachable assembly between the housing 1 and the base plate 2 via bolts and screw holes.

[0029] The housing 1 is provided with a housing mounting and fixing device, and the base plate 2 is provided with a base plate mounting and fixing device, which extends into the housing 1. Depending on the specific application scenario, the housing mounting and fixing device or the base plate mounting and fixing device can be used to connect and fix the entire module product to the user object such as a drone or robot, making the installation more flexible and convenient.

[0030] Specifically, the housing mounting and fixing device includes an outer mounting ring 3 that is arranged around and protrudes outward on the circumference of the housing 1. The outer mounting ring 3 has bolt mating portions, and the entire module can be press-fitted and fixed to the user body by using bolts passing through these portions. The bolt mating portions are configured as clearance openings 4 or bolt holes that pass through the outer mounting ring 3. In this embodiment, the clearance opening 4 is used for installation and fixing with bolts, and the clearance opening 4 is configured as an arc-shaped structure with at least a semi-circle, which can reduce the width of the outer mounting ring 3 to a certain extent, thus fitting into the limited installation space.

[0031] The base plate mounting and fixing device includes a hollow column 5 integrally formed with the base plate 2, and the hollow column 5 extends into the housing 1. A mounting screw groove 6 is coaxially provided with the hollow column 5, and the port of the mounting screw groove 6 faces outwards from the base plate 2. The entire structure can be installed and fixed by fitting the hollow column 5 with bolts. The hollow columns 5 are arranged in pairs opposite each other on the base plate 2, and a reinforcing rib 7 is fixedly connected between the two opposite hollow columns 5. The bottom of the reinforcing rib 7 can be fixedly connected to the base plate 2 to improve the stability of the hollow column 5. To avoid assembly interference between the reinforcing rib 7 and circuit boards inside the housing 1, corresponding circuit board clearance openings can be provided on the reinforcing rib 7 as needed.

[0032] Two transparent camera windows 8 are mounted opposite each other on the housing 1. Two opposing through holes are provided through the housing 1, and the camera windows 8 are fixed and limited within the corresponding through holes. The camera windows 8 can be made of glass, transparent plastic, etc. During the production process, the camera windows 8 are separate from the housing 1 to facilitate the placement of the camera into the housing 1. After the camera is placed, the camera windows 8 are then bonded and fixed to the housing 1 using adhesive. The two camera windows 8 are detachably mounted on the housing 1 and are respectively equipped with cameras to form a dual-mode camera module.

[0033] The housing 1 is equipped with fixing studs 9 for mounting and fixing circuit boards. The circuit board containing the control processing circuitry can be mounted and fixed within the housing 1 by the engagement of bolts with the fixing studs 9. The base plate 2 has an outer groove 10 protruding outwards from the housing 1 and an inner groove 11 protruding inwards from the housing 1. The outer groove 10 is used to accommodate relatively large electrical components such as batteries and capacitors within the housing 1. The inner groove 11 is used to contact the chip within the housing 1 and has a heat-dissipating colloid 12 on its surface. Both the housing 1 and the base plate 2 are metal structures, and the outer groove 10 and the inner groove 11 are integrally formed on the base plate 2. This allows the heat-dissipating colloid 12 to cooperate with the inner groove 11 and the metal base plate 2, achieving heat transfer to the corresponding chip and thus achieving heat dissipation.

[0034] A data cable socket 13 and an venting device are provided through the base plate 2. Protruding protective enclosures 14 are respectively provided around the data cable socket 13 and the venting device on the outer surface of the base plate 2 to protect the corresponding components from damage, thereby avoiding interference with normal communication or ventilation of the housing 1. Specifically, the venting device includes a screw hole 15 penetrating the base plate 2, a venting bolt 16 threaded into the screw hole 15, a central venting hole 17 coaxially provided along the stud of the venting bolt 16, and side venting holes 18 communicating with the central venting hole 17 on the stud of the venting bolt 16. In this embodiment, a camera, circuit board, sensors, and other components are installed inside the housing 1. Various electronic components and chips are used on the circuit board. These components generate heat during operation, which creates thermal pressure inside the housing 1. If the pressure cannot be released and the temperature cannot be lowered in time, it will affect the sensitivity of the sensors. Therefore, it is necessary to set up the venting device to release pressure and heat through the central venting hole 17 and the side venting holes 18. Combined with the heat dissipation effect of the heat dissipation colloid 12, the temperature and pressure inside the housing 1 are kept moderate to ensure the normal operation of the internal electronic components and sensors.

[0035] like Figure 2 , Figure 8 and Figure 9As shown, this embodiment also relates to a camera module, including the module housing described above. Each of the camera windows 8 has a camera 19 mounted on its inner side. A segmented PCB circuit board 20 is connected to each camera 19. The different heights of the fixing studs 9 allow the PCB circuit boards 20 to be layered and fixed within the housing 1 through the cooperation of the fixing studs 9 and bolts, thus fully utilizing the internal space of the housing 1 and achieving a reasonable arrangement and installation of each PCB circuit board 20. A data cable interface 21 corresponding to the data cable socket 13 is fixed on the PCB circuit board 20 near the base plate 2, facilitating external communication of the camera module via a data cable and enabling cooperation with external control and actuator mechanisms to complete corresponding tasks.

[0036] A battery, a capacitor, and several circuit chips are electrically connected to the PCB circuit board 20 near the base plate 2. The specific electronic components used on the PCB circuit board 20, their connections, and layout are well-known in the field of binocular camera 19 technology and will not be described in detail here. The battery and the capacitor are respectively disposed corresponding to the outer groove 10. The outer groove 10 increases the distance between the base plate 2 and the adjacent PCB circuit board 20 to accommodate the relatively large electronic components. Each circuit chip is in contact with the thermal colloid 12 so that heat can be quickly transferred outward through the cooperation of the thermal colloid 12 and the inner groove 11, thereby cooling the circuit chip.

[0037] The description of this utility model is given for illustrative and descriptive purposes only, and is not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the utility model, and to enable those skilled in the art to understand the utility model and design various embodiments with various modifications suitable for a particular purpose.
