Description

Electronic device and imaging module thereof

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on August 22, 2023, with application number 202311063768.9 and invention name “An electronic device and its imaging module”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of electronic equipment, and in particular to an imaging module. The present application also relates to an electronic device having the imaging module. Background Art

[0003] Currently, some electronic devices with adjustable focus lenses are designed to increase the size and cost of the entire device by integrating a motor into the lens. Therefore, in new product development, the motor is often placed within the device itself, with a mechanical transmission structure driving the movement of a detector located within the device. Focusing is achieved by adjusting the distance between the detector and the lens assembly within the lens, thus eliminating the need for a motor within the lens. However, the confined space and numerous parts make assembly and maintenance extremely complex, leading to the introduction of integrated detector motion modules.

[0004] However, in some application scenarios, the optimal fixing method of this detector motion module may not be consistent with the screen imaging direction or the white light camera imaging direction. This results in either the fixing method of the detector motion module being suboptimal, or the motion module needing to be redesigned to maintain the optimal fixing method, which makes it impossible to achieve the purpose of sharing.

[0005] Therefore, it is necessary for those skilled in the art to provide an imaging module in a timely manner. After the imaging module is fixed in the optimal way, the detector inside it can change its direction according to different overall machine requirements to adapt to the imaging direction of the screen and white light.

[0006] Summary of the Invention

DETAILED DESCRIPTION

[0055] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0056] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0057] It should be noted that the directional terms such as "upper end, lower end, left side, right side" described below are all defined based on the drawings in the specification.

[0058] Please refer to FIG. 1 . The imaging module provided in the embodiment of the present application includes a mainboard 1 , a detector 2 , a motion module 3 and a rotation module 4 .

[0059] Among them, the detector 2 is communicated with the main board 1, the main board 1 is fixed on the motion module 3, the motion module 3 is used to move along the first direction (the first direction generally refers to the axial direction of the imaging module), the rotation module 4 is rotatably connected to the motion module 3, the detector 2 is fixed on the rotation module 4, and the rotation module 4 is used to drive the detector 2 to rotate relative to the motion module 3 around the axis of the first direction.

[0060] It can be seen that after the motion module 3 is fixed and placed in the optimal way, the angle of the detector 2 can be adjusted through the rotation module 4 according to the needs of the entire machine to adapt to the imaging direction of the screen and the white light. After the rotation module 4 is re-fixed to the motion module 3, the detector 2 maintains a communication connection with the main board 1.

[0061] When in use, you only need to manually adjust the detector 2 to the required direction, and then fix the imaging module to the required position inside the whole machine. After the signal is connected, all the functions of the detector 2 motion focusing can be realized.

[0062] In this way, assembly and maintenance are very convenient, and quick replacement is easy. At the same time, the detector 2 can adjust the direction function, making this module more versatile, so that many models using this detector 2 can achieve module unification, which is conducive to reducing production costs on single products.

[0063] It should be noted that in the imaging module of the embodiment of the present application, the detector 2 can be freely rotated and positioned at any angle in the circumferential direction of the motion module 3. As a preferred embodiment, the present embodiment specifically describes the free rotation and positioning of the detector 2 at four positions of 0°, 90°, 180°, and 270° in the circumferential direction of the motion module 3.

[0064] Please refer to Figures 2 to 9 together. In order to facilitate the adjustment of the rotation angle of the detector 2, a rotation connection hole 31 is provided at the center position of the motion module 3. Correspondingly, the rotation module 4 is provided with a rotation connection column 41 adapted to the rotation connection hole 31, and the rotation connection column 41 can rotate in the rotation connection hole 31.

[0065] During installation, the rotation connection column 41 of the rotation module 4 is inserted into the rotation connection hole 31 of the motion module 3 , and the rotation module 4 can rotate relative to the motion module 3 around the axis direction of the rotation connection column 41 .

[0066] It should be noted that the rotating connecting column 41 and the rotating connecting hole 31 fit tightly together. In order to facilitate the positioning of the rotating module 4 after adjustment, a damping surface can be set on the inner wall of the rotating connecting hole 31. The damping surface fits tightly together with the rotating connecting column 41, so that the rotating connecting column 41 generates a damping feeling during the rotation process, thereby facilitating the positioning of the rotating connecting column 41 after rotation.

[0067] Of course, according to actual needs, the motion module 3 and / or the rotation module 4 can be made of rubber material to generate damping during the rotation process.

[0068] Please refer to FIG. 10 to FIG. 13 . The imaging module further includes an outer frame 7 . The motion module 3 and the rotation module 4 are installed in the outer frame 7 .

[0069] Furthermore, to facilitate control of the movement of the motion module 3, the imaging module further includes a drive assembly 71. The drive assembly 71 may be disposed within the outer frame 7 and connected to the motion module 3. The drive assembly 71 is configured to drive the motion module 3 to move in a first direction to achieve focusing. The drive assembly 71 may be a motor assembly.

[0070] In some embodiments, a plurality of guide posts 72 are provided in the outer frame 7. Accordingly, the motion module 3 is provided with guide holes 36 adapted to the guide posts 72. Under the driving action of the driving assembly 71, the motion module 3 can move along the guide posts 72, thereby achieving the purpose of focusing.

[0071] In some embodiments, the imaging module also includes a connecting member 5 and an elastic member 6. The connecting member 5 is detachably connected to the rotating connecting column 41. The two ends of the elastic member 6 are respectively abutted against the connecting member 5 and the motion module 3. The elastic member 6 is used to provide elastic force to the connecting member 5 so that the rotating module 4 tends to approach the motion module 3.

[0072] Specifically, the connecting member 5 can be a fixing screw having an external thread, and the rotating connecting column 41 has an internal thread adapted to the external thread. During installation, the fixing screw is screwed onto the rotating connecting column 41. The elastic member 6 can be a compression spring, which is used to drive the rotating module 4 to reset.

[0073] In some embodiments, the motion module 3 is further provided with a receiving groove 32 for receiving the elastic member 6 .

[0074] During installation, the compression spring is assembled in the receiving groove 32 and the fixing screw is screwed in. At this time, the compression spring is in a compressed state, and the rotating module 4 is tightened, thereby fixing the rotating module 4 on the motion module 3 to prevent the rotating module 4 from moving up and down during focusing.

[0075] In some embodiments, in order to facilitate the positioning of the rotating module 4 on the motion module 3, the motion module 3 is provided with a plurality of positioning holes 33 distributed along the circumferential direction. Accordingly, the rotating module 4 is provided with a positioning column 42 adapted to the positioning hole 33. The positioning column 42 can be inserted into the positioning hole 33 to position the rotating module 4 on the motion module 3.

[0076] In this embodiment, in order to realize the free rotation positioning of the detector 2 in the four directions of 0°, 90°, 180° and 270° in the circumferential direction of the motion module 3, the number of positioning holes 33 can be set to four, and the four positioning holes 33 are arranged on the motion module 3 along the circumferential direction and are evenly distributed at 90°.

[0077] In this way, when the rotating module 4 is assembled to the motion module 3 in any of the four orientations of 0°, 90°, 180°, and 270°, the positioning column 42 can cooperate with one of the four positioning holes 33, and the positioning column 42 is inserted into the positioning hole 33 to prevent the rotating module 4 from rotating.

[0078] During assembly, please refer to Figures 14 and 15. First, assemble the motion module 3 into the outer frame 7. The motion module 3 is fixed in the outer frame 7 and can move up and down along the guide column 72 driven by the drive assembly 71. Please refer to Figures 16 and 17. Then, assemble the rotation module 4 into the outer frame 7 in any of the four orientations of 0°, 90°, 180°, and 270°. At this time, the positioning column 42 cooperates with one of the four positioning holes 33 to prevent the rotation module 4 from rotating. Please refer to Figures 18 and 19. Then, assemble the elastic member 6 into the receiving groove 32 and screw on the connecting member 5. At this time, the elastic member 6 is in a compressed state, tightening the rotation module 4, thereby fixing the rotation module 4 on the motion module 3 to prevent the rotation module 4 from moving up and down during focusing. Since the positioning column 42 has been inserted into one of the positioning holes 33, this can effectively prevent the rotation module 4 from moving during focusing, and the entire rotation module 4 is fastened to the motion module 3.

[0079] Please refer to Figures 20 to 23. If you need to rotate the rotating module 4, just press the fixing screws hard until the rotating module 4 protrudes from the entire outer frame 7. At this time, the positioning post 42 has disengaged from the positioning hole 33. After rotating the rotating module 4 to the desired angle, release your hand. The compression spring drives the rotating module 4 to rebound. At this time, the positioning post 42 is reinserted into another one of the four positioning holes 33, so that the rotating module 4 is re-fixed on the motion module 3.

[0080] Please refer to Figures 24 and 25 together. The motherboard 1 is provided with a connector 11, and the detector 2 is provided with a probe 21 (also called a PIN) that is connected to the connector 11. The probe 21 is connected to the connector 11 and is used for signal transmission to achieve communication between the detector 2 and the motherboard 1.

[0081] Based on this, the motion module 3 is provided with a first through hole 34 for the probe 21 to pass through, and the rotation module 4 is provided with a second through hole 43 for the probe 21 to pass through.

[0082] It can be seen that at 0°, 90°, 180° or 270°, the second through holes 43 on the rotating module 4 for the probe 21 to pass through can correspond to a group of first through holes 34 on the moving module 3 for the probe 21 to pass through, so that the probe 21 can be connected to the connector 11, so that the main board 1 and the detector 2 can ensure smooth electrical performance.

[0083] In some embodiments, the motion module 3 is provided with a support platform 35 , which contacts and abuts against the mainboard 1 to limit the mainboard 1 .

[0084] In this embodiment, the detector 2 is fixed on the rotating module 4, the probe 21 of the detector 2 passes through the many first through holes 34, and the mainboard 1 is fixed from the back of the motion module 3. The connector 11 of the mainboard 1 is aligned with the probe 21 and pressed down until the mainboard 1 contacts the support platform 35.

[0085] Please refer to Figures 26 and 27. At this time, the entire module is completed, the detector 2 is fixed on the rotating module 4, the main board 1 is fixed on the motion module 3, and the entire rotating module 4 is fixed to the motion module 3 by fixing screws and compression springs. The entire motion module 3 is located in the outer frame 7 and can move up and down as a whole under the drive of the driving component 71 to achieve the focusing function.

[0086] In this way, the detector 2 and its movement process are completely integrated into a module. Before use, the rotating module 4 in the module is rotated to the required imaging direction consistent with the screen or white light. When in use, it is only necessary to fix the module inside the whole machine in the best way to complete the assembly. The assembly and maintenance are very convenient and easy to replace quickly. At the same time, the detector 2 can adjust the direction function, making this module more versatile, so that many models using this detector 2 can achieve module unification, which is beneficial to reduce the production cost of a single product.
