Description

Technical Field

[0001] This invention relates to the field of camera technology, specifically to a panoramic camera and its assembly method. Background Technology

[0002] With the continuous development and progress of technology and people’s growing demand for recording their rich lives, mobile electronic devices have become increasingly popular. Among them, panoramic cameras, as the core structure of outdoor cameras, have seen a surge in demand.

[0003] However, existing panoramic cameras have two panoramic lenses fixed to the two sides of the same housing. This makes the installation accuracy of the two panoramic lenses highly dependent on the accuracy of the housing's two sides. In other words, fixing two panoramic lenses to both ends of a housing simultaneously requires extremely high precision on the housing's end faces. If the precision of the housing's end faces is not properly controlled, it will directly affect the installation accuracy of the two panoramic lenses. Furthermore, existing panoramic cameras require real-time alignment of the two panoramic lenses during installation. Installing the two panoramic lenses simultaneously from two directions to the two sides of the same housing necessitates constant adjustment of their installation posture, which demands high-precision installation technology and is relatively complex. Therefore, it is necessary to provide a panoramic camera with higher assembly precision while ensuring convenient and flexible installation. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] The panoramic camera provided in the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] On the one hand, such as Figures 1 to 3 As shown, the present invention provides a panoramic camera, including a housing 1, a front lens 2, a rear lens 3, and a mounting plate 4. The panoramic camera has an optical axis o. The front lens 2 is fixed on the housing 1, and the rear lens 3 is fixed on the housing 1 through the mounting plate 4. The front lens 2 and the rear lens 3 are distributed back-to-back along the optical axis o, that is, the field of view of the front lens 2 and the rear lens 3 are oriented in opposite directions, which satisfies the panoramic shooting requirements of the panoramic camera.

[0032] Specifically, such as Figure 3 , Figure 4 and Figure 5 As shown, the housing 1 includes a receiving cavity 11 extending along the optical axis o. A first lens hole 12 and a bracket hole 13 are provided on the housing 1, passing through it. The first lens hole 12 and the bracket hole 13 are located at opposite ends of the housing 1 along the optical axis o, and both are connected to the receiving cavity 11. Therefore, the housing 1 is an annular structure with openings at both ends. The front lens 2 is fixed to the housing 1 by a first fastener 51. The front lens 2 is located inside the receiving cavity 11, and its front optical surface 221 is exposed through the first lens hole 12, preventing the housing 1 from blocking the front optical surface 221 and ensuring that the light collection of the front lens 2 is not affected. It should be noted that the front optical surface 221 refers to the outermost optical surface of the front lens 2, that is, the object side surface of the object-side lens of the front lens 2; that is, light enters the front lens 2 from the front optical surface 221.

[0033] Furthermore, such as Figure 3 , Figure 6 and Figure 7 As shown, the mounting plate 4 is fixed to the housing 1 by the second fastener 52 and closes the bracket hole 13. The mounting plate 4 has a second lens hole 44, which communicates with the receiving cavity 11 and is coaxially aligned with the first lens hole 12. The rear lens 3 is fixed to the mounting plate 4 by the third fastener 53. The rear lens 3 is located inside the receiving cavity 11, and the rear optical surface 321 of the rear lens 3 is exposed through the second lens hole 44, preventing the mounting plate 4 from blocking the rear optical surface 321 of the rear lens 3 and ensuring that the light collection of the rear lens 3 is not affected. It should be noted that the rear optical surface 321 refers to the outermost optical surface of the rear lens 3, that is, the object side surface of the object-side lens of the rear lens 3. Light enters the rear lens 3 from the rear optical surface 321. The first lens hole 12 on the housing 1 and the second lens hole 44 on the mounting plate 4 are respectively spaced apart along the optical axis o. The front optical surface 221 of the front lens 2 is exposed through the first lens hole 12, and the rear optical surface 321 of the rear lens 3 is exposed through the second lens hole 44, so that the field of view of the front lens 2 and the rear lens 3 are opposite, ensuring that the front lens 2 and the rear lens 3 capture field of view ranges with different orientations, thus meeting the panoramic shooting requirements of the panoramic camera.

[0034] Furthermore, both the front lens 2 and the rear lens 3 have a field of view greater than 180°, and their combined imaging range covers a 360° field of view for panoramic shooting. Preferably, the field of view of both the front lens 2 and the rear lens 3 is greater than 180° and less than 260°.

[0035] In this application, the front lens 2 and rear lens 3 of the panoramic camera are respectively mounted on the housing 1 and the mounting plate 4. This reduces the high manufacturing precision requirements of the housing 1 and avoids the installation accuracy of the two lenses of the panoramic camera being affected by the surface precision of the two mounting surfaces of the same component. Furthermore, since the rear lens 3 is fixed to the housing 1 via the mounting plate 4, the installation accuracy of the front lens 2 and rear lens 3 can be controlled by adjusting the positional precision of the mounting plate 4 relative to the housing 1 during installation. In other words, the accuracy of the front lens 2 and rear lens 3 can be corrected by controlling the orientation of the mounting plate 4 relative to the housing 1 during installation, ensuring a more convenient and flexible installation of the panoramic camera, thereby improving the installation accuracy of the panoramic camera.

[0036] In one embodiment, the first fastener 51, the second fastener 52, and the third fastener 53 are all locking screws. Using locking screws can ensure the stability and durability of the connection between the front lens 2, the rear lens 3, the mounting plate 4, and the housing 1.

[0037] In one embodiment, please refer again Figure 4 and Figure 5 The front lens 2 includes a first flange ring 21. A first sealing groove 14 is formed on the housing 1, surrounding the first lens hole 12. A first sealing element 61 is disposed within the first sealing groove 14 and sandwiched between the first sealing groove 14 and the first flange ring 21. By providing the first sealing element 61 between the front lens 2 and the housing 1, the sealing performance of the front lens 2 is ensured, preventing dust or moisture from entering the receiving cavity 11 of the housing 1 through the gap between the first flange ring 21 and the housing 1, thus avoiding affecting the service life and performance of the panoramic camera.

[0038] In one embodiment, a first fixing block 211 is provided on the radially outer side of the first flange ring 21. The first fixing block 211 has a first threaded hole 212 and a first positioning groove 213. A first positioning block 15 protrudes from the surface of the housing 1 facing the first flange ring 21. The first positioning block 15 has a second threaded hole 151 and a first positioning pin 152. A first fastener 51 passes through the first threaded hole 212 and the second threaded hole 151 to form a threaded connection, and the first positioning pin 152 is located in the first positioning groove 213. By providing the first positioning groove 213 on the first fixing block 211 of the front lens 2, and cooperating with the first positioning pin 152 on the first positioning block 15 of the housing 1, the initial positioning of the front lens 2 and the housing 1 is ensured during installation, avoiding large misalignment during installation. Furthermore, the first threaded hole 212 and the second threaded hole 151, combined with the first fastener 51, ensure a stable connection between the front lens 2 and the housing 1. It should be noted that radial direction refers to the direction perpendicular to the optical axis o.

[0039] In one embodiment, please refer to Figure 3 , Figure 6 and Figure 7 The rear lens 3 includes a second flange ring 31. A second sealing groove 41 surrounding the second lens hole 44 is formed on the mounting plate 4. A second sealing element 62 is disposed within the second sealing groove 41 and sandwiched between the second sealing groove 41 and the second flange ring 31. By providing the second sealing element 62 between the rear lens 3 and the mounting plate 4, the sealing performance of the rear lens 3 is ensured, preventing dust or moisture from entering the receiving cavity 11 of the housing 1 through the gap between the second flange ring 31 and the mounting plate 4, thus avoiding affecting the service life and performance of the panoramic camera.

[0040] In one embodiment, a second fixing block 311 is provided on the radially outer side of the second flange ring 31. The second fixing block 311 has a third threaded hole 312 and a second positioning groove 313. A second positioning block 42 protrudes from the surface of the mounting plate 4 facing the second flange ring 31. The second positioning block 42 has a fourth threaded hole 421 and a second positioning pin 422. A third fastener 53 passes through the third threaded hole 312 and the fourth threaded hole 421 to form a threaded connection, and the second positioning pin 422 is located in the second positioning groove 313. By providing the second positioning groove 313 on the second fixing block 311 of the rear lens 3, and cooperating with the second positioning pin 422 on the second positioning block 42 of the mounting plate 4, the initial positioning of the rear lens 3 and the mounting plate 4 is ensured during installation, avoiding large misalignment during installation. Furthermore, the third threaded hole 312 and the fourth threaded hole 421, combined with the third fastener 53, ensure a stable connection between the rear lens 3 and the mounting plate 4.

[0041] In one embodiment, such as Figure 3As shown, the housing 1 has a third sealing groove 16 that surrounds the bracket hole 13. The third sealing element 63 is disposed in the third sealing groove 16 and is sandwiched between the third sealing groove 16 and the mounting plate 4 to ensure the airtightness between the mounting plate 4 and the housing 1.

[0042] In one embodiment, the housing 1 is further provided with a fifth threaded hole 17 surrounding the third sealing groove 16, and the mounting plate 4 is provided with a sixth threaded hole 43. The second fastener 52 passes through the fifth threaded hole 17 and the sixth threaded hole 43 and forms a threaded connection to ensure a stable connection between the mounting plate 4 and the housing 1.

[0043] In one embodiment, such as Figure 6 As shown, the panoramic camera also includes a plastic housing 7. The surface of the plastic housing 7 facing the mounting plate 4 has a snap-fit ​​groove 71, and a clearance hole 72 penetrating the plastic housing 7 is provided in the center of the snap-fit ​​groove 71. The plastic housing 7 is fixed to the outer wall of the mounting plate 4 through the snap-fit ​​groove 71. The mounting plate 4 is embedded in the snap-fit ​​groove 71, and the optical surface of the rear lens 3 is exposed through the clearance hole 72. By designing the plastic housing 7 to cover and enclose the mounting plate 4, the second fastener 52 used to connect the mounting plate 4 and the housing 1 is prevented from being exposed, thus avoiding affecting the aesthetics of the panoramic camera. It also prevents moisture or dust from contaminating the second fastener 52, which could prevent the mounting plate 4 and housing 1 from being disassembled later, thus affecting the replacement or repair of the rear lens 3.

[0044] In one embodiment, such as Figure 1 and Figure 3 As shown, the housing 1 is also provided with a wiring hole 18 extending along the vertical optical axis o. The wiring hole 18 is located between the first lens hole 12 and the bracket hole 13 and is connected to the receiving cavity 11, so as to ensure that the circuit boards on the front lens 2 and the rear lens 3 can be extended out through the wiring hole 18 to realize electrical connection, which facilitates the centralized processing of the wiring connection of the panoramic camera.

[0045] In one embodiment, such as Figure 5 As shown, the front lens 2 includes a first lens element 22, a first cap 23, and a first lens barrel 24. The first cap 23 is threadedly connected to the first lens barrel 24. The edge of the first lens element 22 is located between the first cap 23 and the first lens barrel 24, meaning the edge of the first lens element 22 is fixed to the first lens barrel 24 by the first cap 23. The front optical surface 221 is the outer surface of the first lens element 22, i.e., the object surface of the first lens element 22. The diameter of the first cap 23 is smaller than the diameter of the first lens aperture 12, and the first cap 23 is at least partially exposed through the first lens aperture 12, facilitating easy unscrewing of the first cap 23 to replace the first lens element 22, ensuring that the first lens element 22 can be detachably connected. Similarly, as... Figure 7As shown, the rear lens 3 includes a second lens element 32, a second screw cap 33, and a second lens barrel 34. The second screw cap 33 is threadedly connected to the second lens barrel 34. The edge of the second lens element 32 is located between the second screw cap 33 and the second lens barrel 34, meaning the edge of the second lens element 32 is fixed to the second lens barrel 34 by the second screw cap 33. The rear optical surface 321 is the outer surface of the second lens element 32, i.e., the object surface of the second lens element 32. The diameter of the second screw cap 33 is smaller than the diameter of the second lens aperture 44, and the second screw cap 33 is at least partially exposed through the second lens aperture 44, facilitating easy unscrewing of the second screw cap 33 to replace the second lens element 32, ensuring that the second lens element 32 can be detachably connected.

[0046] On the other hand, the present invention also provides a method for assembling a panoramic camera, for assembling the above-mentioned panoramic camera, comprising the following steps:

[0047] Step 1: Place the front lens 2 along the optical axis o into the receiving cavity 11 of the housing 1, and ensure that the front optical surface 221 of the front lens 2 is exposed through the first lens hole 12 on the housing 1. Fix the front lens 2 to the housing 1 with the first fastener 51, and complete the installation and fixation of the front lens 2 through the housing 1.

[0048] Step 2: Place the rear lens 3 onto the mounting plate 4, ensuring that the rear optical surface 321 of the rear lens 3 is exposed through the second lens hole 44 on the mounting plate 4. Secure the rear lens 3 to the mounting plate 4 using the third fastener 53. The mounting of the lens 3 is then completed by using the mounting plate 4.

[0049] Step 3: Align the mounting plate 4 with the housing 1 along the optical axis o, and install the rear lens 3 into the receiving cavity 11. Align and correct the front lens 2 and rear lens 3, ensuring they are coaxial. Secure the mounting plate 4 to the housing 1 using the second fastener 52, and close the bracket hole 13 of the housing 1. This completes the assembly of the front lens 2 and rear lens 3 onto the panoramic camera. The mounting plate 4, in conjunction with the housing 1, ensures the installation accuracy of the front and rear lenses, reducing the assembly difficulty of the panoramic camera.

[0050] In one embodiment, a plastic housing 7 is provided, on which a snap-fit ​​groove 71 and a clearance hole 72 are provided.
