Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a lens external module. Background Art

[0002] With the rapid development of photography capabilities in electronic devices (such as smartphones and tablets), users are increasingly demanding more diverse shooting effects. Limited by the size and hardware configuration of these devices, external lenses have become an essential accessory for enhancing their shooting performance.

[0003] Currently, the assembly of external lenses and the main body mainly adopts a snap-on connection, which has the advantages of convenient operation and quick lens replacement. However, existing external lenses are mostly connected to the main body through a mechanical snap-on structure. Although this design can achieve quick disassembly and assembly, it relies on manual alignment during the assembly process, making it difficult to ensure that the optical axis of the external lens is strictly collinear with the optical axis of the main body's receiving module. Even if the optical axis of the external lens and the optical axis of the main body's receiving module are collinear during initial assembly, structural deformation caused by loose snaps, external impact, or temperature changes during use may still cause the optical axis of the external lens to deviate from the optical axis of the main body's receiving module, thereby affecting the shooting effect of the electronic device. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides a lens external module, which can reduce the risk of the optical axis of the external lens and the optical axis of the receiving module being non-collinear, thereby improving the shooting effect of the electronic device.

[0005] In order to solve the above technical problems, the present invention provides a lens external module, which is applied to an electronic device, wherein the electronic device includes:

[0006] ontology;

[0007] A receiving module, the receiving module is arranged on the body, and a side of the receiving module away from the body has a first surface, and the first surface is provided with a plurality of first limiting structures;

[0008] The lens external module includes:

[0009] an external lens, wherein a plurality of second limiting structures are provided on the external lens, the plurality of second limiting structures surround an end surface of a first end of the external lens, the plurality of second limiting structures correspond one-to-one to the plurality of first limiting structures, and the second limiting structures are plugged and matched with the corresponding first limiting structures along the direction of the optical axis of the receiving module so that the optical axis of the external lens is coaxial with the optical axis of the receiving module;

[0010] An adapter assembly is rotatably connected to the outer periphery of the first end, and the adapter assembly is detachably connected to the receiving module. The adapter assembly has a light-collecting channel to enable the receiving module to communicate optically with the external lens when the adapter assembly is connected to the receiving module.

[0011] Since there are multiple first limiting structures arranged on the first surface, and multiple second limiting structures arranged on the end surface of the first end of the external lens, and the multiple first limiting structures and the multiple second limiting structures correspond one to one, the second limiting structures and the corresponding first limiting structures are plugged into and matched with each other along the direction of the optical axis of the receiving module. Therefore, the multiple first limiting structures and the corresponding second limiting structures respectively cooperate with each other to limit the external lens in the surface direction of the first surface, and can prevent the external lens from moving relative to the receiving module in a direction perpendicular to the optical axis of the receiving module. By setting multiple first limiting structures and multiple second limiting structures, the external lens can be positioned when the external lens is installed, thereby improving the efficiency and accuracy of the external lens assembly. It can also ensure that the optical axis of the receiving module and the optical axis of the external lens are coaxial when the connection between the adapter assembly and the receiving module becomes loose, thereby improving the shooting effect of the electronic device.

[0012] In some possible implementations, one of the first limiting structure and the second limiting structure includes a limiting through hole, and the other includes a limiting protrusion, the limiting through hole extends along the direction of the optical axis of the receiving module, and the limiting protrusion protrudes along the direction of the optical axis of the receiving module.

[0013] Since the structures of the limiting through hole and the limiting protrusion are simple and easy to design and process, when the first limiting structure is a limiting through hole and the second limiting structure is a limiting protrusion, or when the first limiting structure is a limiting protrusion and the second limiting structure is a limiting through hole, on the one hand, the structural design of the adapter assembly can be simplified, and on the other hand, the structural design and coordination of the first limiting structure and the second limiting structure can be simplified.

[0014] In some possible implementations, the diameter of at least one of the limiting through holes is equal to the diameter of the limiting protrusion, and the diameter of at least one of the limiting through holes is larger than the diameter of the limiting protrusion.

[0015] Since the aperture of at least one limiting through hole is equal to the diameter of the limiting protrusion, and the aperture of at least one limiting through hole is larger than the diameter of the limiting protrusion, when the limiting protrusion is plugged in along the direction of the optical axis of the receiving module, the assembly accuracy between the limiting protrusion and the limiting through hole can be reduced, thereby improving the efficiency of assembling the external lens on the receiving module.

[0016] In some possible implementations, the lens external module also includes a floating connection component, which is arranged between the adapter component and the external lens, and there is a floating gap between the adapter component and the external lens. The floating direction of the floating connection component is parallel to the optical axis of the receiving module, and the floating connection component can make the end face of the first end of the external lens fit with the first surface.

[0017] Since the adapter assembly is detachably connected to the receiving module, when the adapter assembly is connected to the receiving module, the adapter assembly is fixed relative to the receiving module, that is, the adapter assembly is fixed relative to the receiving module. Then, when there is a floating gap between the adapter assembly and the external lens, and the adapter assembly is connected to the receiving module, it means that the external lens is floatingly arranged relative to the receiving module in the optical axis direction of the receiving module, that is, the external lens can move relative to the receiving module in the optical axis direction of the receiving module.

[0018] Since the adapter assembly is detachably connected to the receiving module, and the floating connection assembly is arranged between the adapter assembly and the external lens, there is a floating gap between the adapter assembly and the external lens, and the floating direction of the floating connection assembly is parallel to the optical axis of the receiving module. Therefore, when there is a gap between the end face of the first end of the external lens connected to the adapter assembly and the first surface, the floating connection assembly can drive the external lens to move toward the receiving module until the end face of the first end of the external lens is in contact with the first surface. It can be seen that by setting the floating connection assembly, the external lens can be adjusted so that it is in contact with the first surface from the beginning, thereby ensuring the shooting effect of the electronic device.

[0019] In some possible implementations, the floating connection assembly includes multiple groups, and the multiple groups of floating connection assemblies are arranged around the optical axis of the external lens.

[0020] Because multiple groups of floating connection components are arranged around the optical axis of the external lens, when there is a gap between the end surface of the first end of the external lens connected to the adapter assembly and any part of the first surface, the corresponding floating connection component can adjust the external lens to tilt it toward the position with the gap, thereby ensuring that the end surface of the first end of the external lens is completely in contact with the first surface, further ensuring the shooting effect of the electronic device.

[0021] In some possible implementations, the floating connection assembly includes a first fastener and an elastic member, the first fastener connects the adapter assembly and the external lens in the optical axis direction of the receiving module, the floating gap is located between the adapter assembly and the external lens, and the elastic member is arranged between the adapter assembly and the external lens in the optical axis direction of the receiving module and is in a compressed state, so that when a gap appears between the end face of the first end of the external lens and the first surface, the elastic member can push the external lens toward the receiving module so that the end face of the first end of the external lens is in contact with the first surface.

[0022] Since the adapter assembly is detachably connected to the receiving module, that is, when the adapter assembly is connected to the receiving module, the adapter assembly is fixed relative to the receiving module, and since the first fastener connects the adapter assembly and the external lens in the optical axis direction of the receiving module, the external lens is fixed relative to the adapter assembly in a direction perpendicular to the optical axis of the receiving module.

[0023] And because the elastic member is arranged between the adapter assembly and the external lens in the optical axis direction of the receiving module and is in a compressed state, the elastic member can push the external lens to move relative to the receiving module in the optical axis direction of the receiving module. In this way, in order to ensure the camera effect of the lens external module, the end face of the first end of the external lens is made to fit with the first surface.

[0024] In other words, when a gap appears between the end face of the first end of the external lens and the first surface, the elastic potential energy accumulated by the elastic member in the compressed state can push the external lens to move relative to the receiving module of the main body until the end face of the first end of the external lens is in contact with the first surface, thereby ensuring the camera effect of the external lens module.

[0025] It can be seen that the connection structure of the floating connection assembly formed by the first fastener and the elastic member is simple and easy to assemble.

[0026] In some possible implementations, the adapter assembly includes a fixed ring, a rotating ring and a sleeve ring, the fixed ring and the rotating ring are stacked, the fixed ring is connected to the external lens on the side facing the rotating ring, the rotating ring can rotate relative to the fixed ring, the sleeve ring is sleeved outside the fixed ring and the rotating ring, and can rotate relative to the fixed ring, the sleeve ring is connected to the rotating ring, when the sleeve ring rotates relative to the receiving module along a first direction, the sleeve ring can be connected to the receiving module, and when the sleeve ring rotates in a direction opposite to the first direction, the sleeve ring can be detached from the receiving module.

[0027] It can be seen that the adapter assembly can assemble the external lens to the receiving module by rotating along the first direction, and can remove the external lens from the receiving module by rotating along the direction opposite to the first direction. The operation is simple, and the gap between the external lens and the receiving module in the optical axis direction of the receiving module can be eliminated as much as possible, thereby improving the camera quality of the electronic device.

[0028] In some possible implementations, a third limiting structure is provided on the collar, and a fourth limiting structure is provided on the rotating ring. The third limiting structure and the fourth limiting structure are plugged into and matched with each other in the optical axis direction of the receiving module, and can prevent one of the rotating ring and the collar from moving relative to the other in a direction perpendicular to the optical axis of the receiving module.

[0029] Since a third limiting structure is provided on the sleeve ring and a fourth limiting structure is provided on the rotating ring, the third limiting structure and the fourth limiting structure are plugged into and matched in the optical axis direction of the receiving module. Therefore, the freedom of the rotating ring and the sleeve ring in the direction perpendicular to the optical axis of the receiving module can be limited, thereby preventing either the rotating ring or the sleeve ring from moving relative to the other in the direction perpendicular to the optical axis of the receiving module, thereby ensuring the reliability of the rotational connection between the sleeve ring and the receiving module.

[0030] In some possible implementations, the collar is provided with a first buckle, and the receiving module is provided with a second buckle. When the collar rotates relative to the receiving module along the first direction, the first buckle and the second buckle can be buckled and fixed. When the collar rotates relative to the receiving module in a direction opposite to the first direction or continues to rotate along the first direction, the first buckle can be disengaged from the second buckle.

[0031] Since the collar and the receiving module can be fastened and fixed by the first buckle and the second buckle when the collar rotates relative to the receiving module in a first direction, and the first buckle is disengaged from the second buckle when the collar rotates relative to the receiving module in a direction opposite to the first direction or continues to rotate in the first direction, therefore, compared with fastener fixation, it can ensure that the first surface fits the end face of the first end of the external lens as much as possible, and the assembly is simple and the assembly efficiency is high.

[0032] In some possible implementations, the first buckle and the second buckle each include a plurality, and the plurality of first buckles correspond to the plurality of second buckles one-to-one, and the plurality of first buckles are distributed at intervals along the circumference of the ring.

[0033] Since the multiple first buckles correspond to the multiple second buckles one-to-one, and the multiple first buckles are distributed at intervals along the circumference of the ring, the connection strength between the adapter assembly and the receiving module can be improved, thereby improving the reliability of the external lens connection.

[0034] In some possible implementations, the body is further provided with a rotation-stopping structure and an operating member, the operating member being provided on the body, the rotation-stopping structure having a first state and a second state, wherein in the first state, the rotation-stopping structure cooperates with the adapter assembly to prevent the adapter assembly from rotating relative to the receiving module, and in the second state, the rotation-stopping structure is disengaged from the adapter assembly;

[0035] The operating member is used to operate the anti-rotation structure to switch it from the first state to the second state.

[0036] In this way, the collar in the adapter assembly can be prevented from continuously rotating along the first direction relative to the receiving module, thereby being disengaged from the receiving module and affecting the reliability of the snap connection between the collar and the receiving module.

[0037] In some possible implementations, a reset member is provided between the fixed ring and the rotating ring. When the ring rotates relative to the receiving module along a first direction, the reset member is stretched. When the first buckle disengages from the second buckle, the reset member can drive the ring to rotate relative to the fixed ring to reset.

[0038] Therefore, by providing the reset member, on the one hand, when the collar rotates relative to the receiving module, it can prevent the collar from rotating too fast relative to the receiving module and affecting other components; on the other hand, it can facilitate the disassembly of the external lens.

[0064] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0065] In the present invention, terms such as "upper," "lower," "left," "right," "front," "back," "top," "bottom," "inner," "outer," "vertical," "horizontal," "transverse," and "longitudinal" indicate positions or locations based on the positions or locations shown in the accompanying drawings. These terms are primarily intended to better describe the present invention and its embodiments and are not intended to limit the devices, elements, or components indicated to having a specific orientation, or to being constructed or operated in a specific orientation.

[0066] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0067] Furthermore, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on specific circumstances.

[0068] Furthermore, the terms "first," "second," etc., are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0069] As described in the background of this application, the existing assembly of external lenses and the main body mainly adopts a snap-on connection, which has the advantages of convenient operation and quick lens replacement. However, the existing external lenses are mostly connected to the main body through a mechanical snap-on structure. Although this type of design can achieve rapid disassembly and assembly, it relies on manual alignment during the assembly process, making it difficult to ensure that the optical axis of the external lens is strictly collinear with the optical axis of the main body's receiving module. Even if the optical axis of the external lens is collinear with the optical axis of the main body's receiving module during initial assembly, structural deformation caused by loose snaps, external force collisions, or temperature changes during use may still cause the optical axis of the external lens to deviate from the optical axis of the main body's receiving module, thereby affecting the shooting effect of the electronic device.

[0070] In order to solve the technical problems mentioned in the background technology, the present invention provides a lens external module, which can reduce the risk of the optical axis of the external lens and the optical axis of the receiving module being non-collinear, thereby improving the shooting effect of the electronic device.

[0071] The present application is described in detail below through specific embodiments:

[0072] See also Figure 1 、 Figure 2 and Figure 3 The embodiment of the present application provides a lens external module 100, which is applied to an electronic device 200. The electronic device 200 includes a body 110 and a receiving module 120 arranged on the body 110. The receiving module 120 has a first surface 111 on a side away from the body 110. The first surface 111 is provided with a plurality of first limiting structures 121; the lens external module 100 includes an external lens 130 and an adapter assembly 140, wherein the external lens 130 is provided with a plurality of second limiting structures 131, and the plurality of second limiting structures 131 surround the first limiting structures 121 of the external lens 130. On the end face of the first end, multiple second limiting structures 131 correspond one-to-one to multiple first limiting structures 121, and the second limiting structures 131 are plugged into and matched with the corresponding first limiting structures 121 along the direction of the optical axis of the receiving module 120, so that the optical axis of the external lens 130 is coaxial with the optical axis of the receiving module 120; the adapter component 140 is rotatably connected to the outer periphery of the first end, and the adapter component 140 is detachably connected to the receiving module 120, and the adapter component 140 has a lighting channel 14A, so that when the adapter component 140 is connected to the receiving module 120, the receiving module 120 and the external lens 130 can communicate optically.

[0073] Among them, the electronic device 200 can be a smart phone, tablet computer, etc. The main body 110 of the lens external module 100 has a front and a back, a display screen is provided on the front, and a receiving module 120 is provided on the front and / or back, and the receiving module 120 is used for shooting.

[0074] It should be noted that the above-mentioned receiving module 120 can be a simple signal receiving module without optical function, which receives the image signal of the external lens through optical communication. It can also be an image sensor, while the external lens only has an optical module. It can also be a camera module, that is, the camera module includes an image sensor and a first optical module, and the external lens has a second optical module. The first optical module and the second optical module can be used in combination, or the first optical module can be used alone.

[0075] The first surface 111 refers to an end surface extending out of or exposed from the main body 110 , and the first end of the external lens 130 refers to an end connected to the main body 110 .

[0076] The above-mentioned multiple refers to two or more than two, such as two, three, four, etc.

[0077] The optical axis of the receiving module 120 is as follows: Figure 2 The dotted line in A1 is shown in the figure.

[0078] Since there are multiple first limiting structures 121 disposed on the first surface 111, there are multiple second limiting structures 131 disposed on the end surface of the first end of the external lens 130 (eg Figure 3 The second limiting structures 131 shown in the figure are two), and the multiple first limiting structures 121 and the multiple second limiting structures 131 correspond one to one. The second limiting structures 131 are plugged into and matched with the corresponding first limiting structures 121 along the direction of the optical axis of the receiving module 120. Therefore, the multiple first limiting structures 121 and the corresponding multiple second limiting structures 131 can respectively cooperate with each other to limit the external lens 130 in the surface direction of the first surface 111, and can prevent the external lens 130 from moving relative to the receiving module 120 in a direction perpendicular to the optical axis of the receiving module 120. By providing the multiple first limiting structures 121 and the multiple second limiting structures 131, the external lens 130 can be positioned when the external lens 130 is installed, thereby improving the efficiency and accuracy of the external lens assembly. It can also ensure that the optical axis of the receiving module 120 and the optical axis of the external lens 130 are coaxial when the connection between the adapter assembly 140 and the receiving module 120 becomes loose, thereby improving the shooting effect of the electronic device.

[0079] It should be noted that the detachable connection between the adapter component 140 and the receiving module 120 includes that the adapter component 140 is connected to the receiving module 120 by screws, or that the adapter component 140 and the receiving module 120 are fixed by rotation and clamping (this example is mainly used for explanation in this embodiment).

[0080] In some possible embodiments, see Figure 2 and Figure 3The first limiting structure 121 includes a limiting through hole, which extends along the direction of the optical axis of the receiving module 120, and the second limiting structure 131 includes a limiting protrusion, which protrudes from the end surface of the first end of the external lens 130 along the direction of the optical axis of the receiving module 120; or, the first limiting structure 121 includes a limiting protrusion, which protrudes from the first surface 111 along the direction of the optical axis of the receiving module 120, and the second limiting structure 131 includes a limiting through hole, which extends along the direction of the optical axis of the receiving module 120.

[0081] Since the structures of the limiting through hole and the limiting protrusion are simple and easy to design and process, when the first limiting structure 121 is a limiting through hole and the second limiting structure 131 is a limiting protrusion, or when the first limiting structure 121 is a limiting protrusion and the second limiting structure 131 is a limiting through hole, on the one hand, the structural design of the adapter assembly 140 can be simplified, and on the other hand, the structural design and coordination of the first limiting structure 121 and the second limiting structure 131 can be simplified.

[0082] Among them, optionally, the limiting through hole can be a circular hole, the corresponding limiting protrusion is cylindrical, and the diameter of the limiting through hole is approximately equal to the diameter of the limiting protrusion. In this way, the external lens 130 can be prevented from rotating around the optical axis of the receiving module 120 relative to the first surface 111, thereby improving the effect of the first limiting structure 121 and the second limiting structure 131 cooperating with each other to limit the external lens 130.

[0083] Optionally, at least one limiting through hole can be a circular hole, and at least one limiting through hole can be an elliptical hole, and the corresponding limiting protrusions are cylinders with a diameter approximately equal to the circular hole. In this way, the assembly accuracy of the first limiting structure 121 and the second limiting structure 131 can be reduced while achieving the limitation of the external lens 130.

[0084] In some possible embodiments, the diameter of at least one limiting through hole is equal to the diameter of the limiting protrusion, and the diameter of at least one limiting through hole is larger than the diameter of the limiting protrusion.

[0085] Since the aperture of at least one limiting through hole is equal to the diameter of the limiting protrusion, and the aperture of at least one limiting through hole is larger than the diameter of the limiting protrusion, when the limiting protrusion is plugged in along the direction of the optical axis of the receiving module 120, the assembly accuracy between the limiting protrusion and the limiting through hole can be reduced, thereby improving the efficiency of assembling the external lens 130 on the receiving module 120.

[0086] It should be noted that when the aperture of the limiting through hole is larger than the diameter of the limiting protrusion, the shape of the limiting through hole can be circular, elliptical or other structures.

[0087] In some possible embodiments, see Figures 4 to 7The lens external module 100 further includes a floating connection component 150, which is disposed between the adapter component 140 and the external lens 130. There is a floating gap (i.e., Figure 7 The floating direction of the floating connection component 150 is parallel to the optical axis of the receiving module 120 , and the floating connection component 150 can make the end surface of the first end of the external lens 130 fit with the first surface 111 .

[0088] Since the adapter assembly 140 is detachably connected to the receiving module 120, when the adapter assembly 140 is connected to the receiving module 120, the adapter assembly 140 is fixed relative to the receiving module 120, that is, the adapter assembly 140 is fixed relative to the receiving module 120. Then, when there is a floating gap between the adapter assembly 140 and the external lens 130, and the adapter assembly 140 is connected to the receiving module 120, it means that the external lens 130 is floatingly arranged relative to the receiving module 120 in the optical axis direction of the receiving module 120, that is, the external lens 130 can move relative to the receiving module 120 in the optical axis direction of the receiving module 120.

[0089] Since the adapter assembly 140 is detachably connected to the receiving module 120, and the floating connection assembly 150 is disposed between the adapter assembly 140 and the external lens 130, a floating gap is provided between the adapter assembly 140 and the external lens 130, and the floating direction of the floating connection assembly 150 is parallel to the optical axis of the receiving module 120, when a gap exists between the end face of the first end of the external lens 130 connected to the adapter assembly 140 and the first surface 111, the floating connection assembly 150 can drive the external lens 130 to move toward the receiving module 120 until the end face of the first end of the external lens 130 is in contact with the first surface 111. Therefore, by providing the floating connection assembly 150, the external lens 130 can be adjusted so that it is in contact with the first surface 111 from the beginning, thereby ensuring the shooting effect of the electronic device.

[0090] In some possible embodiments, see Figure 4 and Figure 5 The floating connection assembly 150 includes multiple groups, and the multiple groups of floating connection assemblies 150 are arranged around the optical axis of the external lens 130.

[0091] The above-mentioned multiple groups refer to two or more groups. For example, as shown in FIG. 5 , the floating connection assembly 150 includes three groups, and the three groups of floating connection assemblies 150 are arranged around the optical axis of the external lens 130 .

[0092] Because the multiple floating connection assemblies 150 are arranged around the optical axis of the external lens 130, when a gap exists between the end surface of the first end of the external lens 130 connected to the adapter assembly 140 and any position of the first surface 111, the corresponding floating connection assembly 150 can adjust the external lens 130 to tilt it toward the position with the gap, thereby ensuring that the end surface of the first end of the external lens 130 is completely in contact with the first surface 111, further ensuring the shooting effect of the electronic device.

[0093] Optionally, multiple groups of floating connection components 150 are arranged at equal intervals around the optical axis of the external lens 130. In this way, on the one hand, the uniformity of the connection force between the adapter component 140 and the external lens 130 can be ensured, and on the other hand, the shooting effect of the electronic device can be further improved.

[0094] In some possible embodiments, see Figure 5 and Figure 7 The floating connection assembly 150 includes a first fastener 151 and an elastic member 152. The first fastener 151 connects the adapter assembly 140 and the external lens 130 in the optical axis direction of the receiving module 120. A floating gap is located between the adapter assembly 140 and the external lens 130. The elastic member 152 is arranged between the adapter assembly 140 and the external lens 130 in the optical axis direction of the receiving module 120 and is in a compressed state. When a gap appears between the end surface of the first end of the external lens 130 and the first surface 111, the elastic member 152 can push the external lens 130 toward the receiving module 120, so that the end surface of the first end of the external lens 130 is in contact with the first surface 111.

[0095] The fasteners mentioned above may be screws, bolts, etc.; the elastic member 152 may be a compression spring, a rubber column, etc.

[0096] Since the adapter assembly 140 is detachably connected to the receiving module 120, that is, when the adapter assembly 140 is connected to the receiving module 120, the adapter assembly 140 is fixed relative to the receiving module 120, and since the first fastener 151 connects the adapter assembly 140 and the external lens 130 in the direction of the optical axis of the receiving module 120, the external lens 130 is fixed relative to the adapter assembly 140 in a direction perpendicular to the optical axis of the receiving module 120.

[0097] Furthermore, since the elastic member 152 is disposed between the adapter assembly 140 and the external lens 130 in the optical axis direction of the receiving module 120 and is in a compressed state, the elastic member 152 can push the external lens 130 to move relative to the receiving module 120 in the optical axis direction of the receiving module 120. In this way, in order to ensure the camera effect of the external lens module, the end surface of the first end of the external lens 130 is made to fit with the first surface 111.

[0098] In other words, when a gap appears between the end surface of the first end of the external lens 130 and the first surface 111, the elastic potential energy accumulated by the compressed elastic member 152 can push the external lens 130 to move relative to the receiving module 120 of the main body 110 until the end surface of the first end of the external lens 130 is in contact with the first surface 111, thereby ensuring the camera effect of the external lens module.

[0099] It can be seen that the connection structure of the floating connection assembly 150 formed by the first fastener 151 and the elastic member 152 is simple and easy to assemble.

[0100] Specifically, see Figure 7 The first fastener 151 is a screw, and the end of the screw has a limiting portion and a connecting portion. The end surface of the first end of the external lens 130 includes a first surface and a second surface. The first surface is located in the middle, and the second surface surrounds the first surface and is along the optical axis of the external lens 130 and close to the direction of the receiving module 120. The first surface protrudes from the second surface. A connecting column is provided on the second surface, and a screw hole is provided in the connecting column. The connecting portion is threadedly connected to the screw hole. The elastic member 152 is provided on the connecting column such as a spring. One end of the elastic member 152 abuts against the limiting portion, and the other end abuts against the second surface or the fixing ring in the adapter assembly 140. In this way, the elastic member 152 is in a compressed state. When the adapter assembly is connected, When the adapter assembly 140 is connected to the receiving module 120, the limiting portion will abut against the edge of the end surface of the receiving module 120. If a gap appears between the end surface of the first end of the external lens 130 and the first surface 111, a gap will appear between the limiting portion and the edge of the end surface of the receiving module 120. Because the adapter assembly 140 is fixed relative to the receiving module 120 in the direction of the optical axis of the receiving module 120, the elastic member 152 will push the limiting portion toward the receiving module 120 until it abuts against it. During this process, the external lens 130 will be pushed toward the receiving module 120 until the gap between the end surface of the first end of the external lens 130 and the first surface 111 is eliminated.

[0101] In addition, in some other embodiments, the floating connection assembly 150 can also be a clamping structure and a compression spring arranged between the adapter assembly 140 and the external lens 130, and the compression spring is arranged between the adapter assembly 140 and the first end of the external lens 130 and is in a compressed state.

[0102] In some possible embodiments, see Figure 8 and Figure 9The adapter assembly 140 includes a fixed ring 141, a rotating ring 142 and a sleeve ring 143. The fixed ring 141 and the rotating ring 142 are stacked. The fixed ring 141 is connected to the external lens 130 on the side facing the rotating ring 142. The rotating ring 142 can rotate relative to the fixed ring 141. The sleeve ring 143 is sleeved outside the fixed ring 141 and the rotating ring 142 and can rotate relative to the fixed ring 141. The sleeve ring 143 is connected to the rotating ring 142. When the sleeve ring 143 rotates relative to the receiving module 120 along a first direction, the sleeve ring 143 can be engaged with the receiving module 120. When the sleeve ring 143 rotates in a direction opposite to the first direction, the sleeve ring 143 can be separated from the receiving module 120.

[0103] Among them, the ring 143 includes an annular portion and a limiting portion that are connected to each other. The annular portion is arranged outside the fixed ring 141 and the rotating ring 142. The limiting portion is connected to one end of the annular portion along the axial direction of the annular portion. The surface of the limiting portion facing the internal space of the annular portion is the inner end surface of the ring 143 facing one end of the receiving module 120. The rotating ring 142, the fixed ring 141 and the limiting portion are stacked in sequence.

[0104] Since the fixed ring 141 is connected to the external lens 130 and is disposed between the rotating ring 142 and the inner end surface of the sleeve ring 143 facing the receiving module 120, the rotating ring 142 can be limited by the external lens 130 and the fixed ring 141. Since the rotating ring 142 is connected to the sleeve ring 143, the sleeve ring 143 is limited by the connection with the rotating ring 142. In this way, the adapter assembly 140 is connected to the external lens 130.

[0105] In addition, since the fixed ring 141 is connected to the external lens 130, the fixed ring 141 is fixed relative to the external lens 130. Since both the rotating ring 142 and the sleeve ring 143 can rotate relative to the fixed ring 141, the rotating ring 142 and the sleeve ring 143 can rotate relative to the external lens 130. Moreover, since the rotating ring 142 is connected to the sleeve ring 143, the rotating ring 142 and the sleeve ring 143 can rotate synchronously relative to the fixed ring 141.

[0106] In addition, by rotating the sleeve ring 143 and the rotating ring 142 relative to the fixed ring 141, the adapter assembly 140 can be connected to the receiving module 120, thereby connecting the external lens 130 to the receiving module 120, that is, the electronic device achieves the shooting purpose of the external lens 130 and the receiving module 120, and at the same time performs preliminary positioning of the external lens 130.

[0107] It can be seen that the adapter assembly 140 can assemble the external lens 130 to the receiving module 120 by rotating along the first direction, and can remove the external lens 130 from the receiving module 120 by rotating along the direction opposite to the first direction. The operation is simple, and the gap between the external lens 130 and the receiving module 120 in the optical axis direction of the receiving module 120 can be eliminated as much as possible, thereby improving the camera quality of the electronic device.

[0108] It should be noted that the first direction refers to the clockwise direction or counterclockwise direction around the optical axis of the receiving module 120. For example, the first direction is the clockwise direction around the optical axis of the receiving module 120, and the direction opposite to the first direction is the counterclockwise direction around the optical axis of the receiving module 120. Figure 8 The arrow z1 shown in FIG is a first direction, and the arrow z2 is a direction opposite to the first direction.

[0109] In addition, optionally, the first fastener 151 in the floating connection assembly 150 fastens the external lens 130 and the fixing ring 141 , the elastic member 152 is disposed between the external lens 130 and the fixing ring 141 , and the floating gap is located between the fixing ring 141 and the external lens 130 .

[0110] In some possible embodiments, see Figure 8 and Figure 9 A third limiting structure 1431 is provided on the ring 143, and a fourth limiting structure 1421 is provided on the rotating ring 142. The third limiting structure 1431 and the fourth limiting structure 1421 are plugged into and matched with each other in the optical axis direction of the receiving module 120, which can prevent either the rotating ring 142 or the ring 143 from moving relative to the other in the direction perpendicular to the optical axis of the receiving module 120.

[0111] Among them, one of the third limiting structure 1431 and the fourth limiting structure 1421 is a limiting hole and the other is a limiting protrusion. Optionally, the third limiting structure 1431 and the fourth limiting structure 1421 include multiple, and the multiple third limiting structures 1431 and the fourth limiting structure 1421 are spaced apart around the optical axis of the receiving module 120 to improve the limiting effect of the third limiting structure 1431 and the fourth limiting structure 1421 on the rotating ring 142 and the sleeve ring 143.

[0112] Since a third limiting structure 1431 is provided on the ring 143 and a fourth limiting structure 1421 is provided on the rotating ring 142, the third limiting structure 1431 and the fourth limiting structure 1421 are plugged into and matched with each other in the optical axis direction of the receiving module 120. Therefore, the freedom of the rotating ring 142 and the ring 143 in the direction perpendicular to the optical axis of the receiving module 120 can be limited, thereby preventing either the rotating ring 142 or the ring 143 from moving relative to the other in the direction perpendicular to the optical axis of the receiving module 120, thereby ensuring the reliability of the rotational connection between the ring 143 and the receiving module 120.

[0113] In some possible embodiments, see Figure 9 and Figure 10 A first buckle 1432 is provided on the ring 143, and a second buckle 1111 is provided on the receiving module 120. When the ring 143 rotates relative to the receiving module 120 along the first direction, the first buckle 1432 can be fastened and fixed with the second buckle 1111. When the ring 143 rotates relative to the receiving module 120 in a direction opposite to the first direction or continues to rotate relative to the receiving module 120 along the first direction, the first buckle 1432 can be disengaged from the fastening of the second buckle 1111.

[0114] Specifically, a small boss is formed on the outer periphery of the receiving module 120, and a first protrusion extends from the peripheral wall of the small boss as the second snap 1111, and a snap-fit gap is provided between the first protrusion and the receiving module 120. A second protrusion is formed on the inner side wall of the ring 143 protruding toward the receiving module 120 as the first snap 1432. When the ring 143 rotates, the second protrusion is inserted into the snap-fit gap and abuts against the first protrusion, thereby achieving the snapping of the first snap 1432 and the second snap 1111.

[0115] Since the ring 143 and the receiving module 120 can be fastened and fixed by the first buckle 1432 and the second buckle 1111 when the ring 143 rotates relative to the receiving module 120 in a first direction, and the first buckle 1432 is disengaged from the fastening of the second buckle 1111 when the ring 143 rotates relative to the receiving module 120 in a direction opposite to the first direction or continues to rotate in the first direction, therefore, compared with fastener fixation, it is possible to ensure that the first surface 111 fits the end face of the first end of the external lens 130 as much as possible, and the assembly is simple and the assembly efficiency is high.

[0116] In some possible embodiments, the first buckle 1432 and the second buckle 1111 each include a plurality, and the plurality of first buckles 1432 correspond to the plurality of second buckles 1111 one to one, and the plurality of first buckles 1432 are distributed at intervals along the circumference of the ring 143 .

[0117] The above-mentioned multiple refers to a number of two or more.

[0118] In addition, the shapes and sizes of the multiple first buckles 1432 can be the same or different. For example, the length of at least one first buckle 1432 among the multiple first buckles 1432 is longer than the lengths of the other first buckles 1432, and the same applies to the second buckle 1111.

[0119] In addition, the first buckles 1432 are distributed at intervals along the circumference of the collar 143 , including multiple first buckles 1432 distributed at equal intervals along the circumference of the collar 143 , or at least some of the multiple first buckles 1432 are distributed at equal intervals along the circumference of the collar 143 .

[0120] Since the multiple first buckles 1432 correspond to the multiple second buckles 1111 one by one, and the multiple first buckles 1432 are distributed at intervals along the circumference of the ring 143, the connection strength between the adapter assembly 140 and the receiving module 120 can be improved, thereby improving the reliability of the connection of the external lens 130.

[0121] In some possible embodiments, see Figure 11 and Figure 12 A stop-rotation structure 160 and an operating member 170 are also provided on the main body 110. The operating member 170 is provided on the main body 110. The stop-rotation structure 160 has a first state and a second state. In the first state, the stop-rotation structure 160 cooperates with the adapter assembly to prevent the adapter assembly from being relative to the receiving module. In the second state, the stop-rotation structure 160 is disengaged from the adapter assembly; the operating member 170 is provided on the main body 110. The operating member 170 is used to operate the stop-rotation structure 160 to switch it from the first state to the second state.

[0122] Therefore, in combination with the above embodiment, in the first state, the anti-rotation structure 160 cooperates with the ring 143 to prevent the ring 143 in the adapter assembly 140 from continuously rotating in the first direction relative to the receiving module 120, thereby disengaging from the receiving module 120 and affecting the reliability of the snap-on connection between the ring 143 and the receiving module 120.

[0123] Optionally, the anti-rotation structure 160 includes a groove 162 provided on the ring 143 and a retractable boss 161 provided on the main body 110, and the retractable boss 161 is connected to the operating member 170. In the first state of the anti-rotation structure 160, the boss 161 and the groove 162 are engaged with each other, thereby preventing the ring 143 from continuing to rotate in the first direction relative to the receiving module 120. In the second state of the anti-rotation structure 160, the boss 161 and the groove 162 are disengaged, and the ring 143 can continue to rotate in the first direction or in a direction opposite to the first direction to disengage the ring 143 from the receiving module 120.

[0124] Optionally, the operating member 170 is a push button. When the push button is pressed, the push button can drive the telescopic boss 161 to contract, thereby disengaging from the groove 162.

[0125] In some possible embodiments, see Figure 13 A reset member 144 is provided between the fixed ring 141 and the rotating ring 142. When the sleeve ring 143 rotates relative to the receiving module 120 along the first direction, the reset member 144 is stretched. When the first buckle 1432 disengages from the second buckle 1111, the reset member 144 can drive the sleeve ring 143 to rotate relative to the fixed ring 141 to reset.

[0126] The reset member 144 may be a tension spring, a torsion spring, or the like.

[0127] Therefore, by providing the reset member 144 , on the one hand, when the collar 143 rotates relative to the receiving module 120 , it can prevent the collar 143 from rotating too fast relative to the receiving module 120 and affecting other components; on the other hand, it can facilitate the disassembly of the external lens 130 .

[0128] Additionally, optionally, see Figure 11 and Figure 12 A first electrical contact 181 and an electrical connector that are electrically connected to each other are provided on the adapter assembly 140, and the electrical connector is electrically connected to the external lens 130. A second electrical contact 182 is provided on the receiving module 120. When the external lens 130 is connected to the receiving module 120 through the adapter assembly 140, the external lens 130 can communicate with the receiving module 120.

[0129] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
