Description

Technical Field

[0001] The embodiments of the present application relate to the field of optical transmission, and in particular to an assembly component, a lens module and an optical communication terminal. Background Art

[0002] The adjustment accuracy of optical components directly affects the optical performance of optical components. This impact is particularly large in areas such as high-speed information transmission. For example, in space optical communication systems, space laser channels are usually used to transmit information, and acquisition, tracking, and pointing (ATP) systems are required to establish and maintain communication links. The ATP optical system includes multiple sets of optical modules. In order to ensure the quality of communication, the relative position tolerance of optical components is in the micron (μm) level. Therefore, during the assembly process, reducing the offset of the relative position of optical components becomes an important factor in ensuring the quality of optical communication. Summary of the invention

[0003] The embodiments of the present application provide an assembly component, a lens module and an optical communication terminal, which are intended to reduce the offset of the relative positions of optical elements.

[0004] In order to achieve the above-mentioned purpose, this application adopts the following technical solution.

[0005] In the first aspect, an embodiment of the present application provides an assembly component. The assembly component includes a mounting frame, a base and a first assembly structure. The mounting frame includes a main bracket and a mounting portion connected to each other. The base is connected to the mounting portion, and a first gap is provided between the main bracket and the base. The first assembly structure includes an assembly rod, a first buffer, a second buffer and a pressure plate. The pressure plate is located on a side of the main bracket away from the base, the first buffer is located in the first gap, and the second buffer is located between the pressure plate and the main bracket; the assembly rod passes through the main bracket and is connected to the pressure plate at one end and to the base at the other end. Because the mounting portion is connected to the base, the force between the mounting frame and the base is transmitted through the mounting portion, so that the base and the mounting frame support each other, and the mounting portion and the base have a determined relative position relationship. One end of the assembly rod is connected to the pressure plate, and the other end of the assembly rod is connected to the base. Therefore, the assembly rod connects the main bracket and the base. There are at least two force points between the mounting frame and the base, one from the mounting portion and the other from the assembly rod. Compared with a cantilever structure with one stress point, two stress points make the stress between the mounting frame and the base more uniform. Avoid bending of one end of the main bracket away from the mounting portion or one end of the base away from the mounting portion due to internal stress. Because there is a first gap between the base and the main bracket, the first buffer is located in the first gap, and the first buffer can buffer the interaction force between the base and the main bracket. Reduce the bending of the base and the main bracket caused by the interaction force between the base and the main bracket, and reduce the change in the relative position of the base and the main bracket. Similarly, the second buffer located between the main bracket and the pressure plate can buffer the force between the main bracket and the pressure plate. Reducing the interaction force between the main bracket and the pressure plate causes the relative position of the main bracket and the pressure plate to change. Then, the first buffer and the second buffer effectively relieve the stress between the main bracket and the base to cause the main bracket and the base to bend. In the process of assembling the mounting frame and the base, the first assembly structure connecting the mounting frame and the base does not change the relative position of any two positions on the mounting frame (such as the end of the main bracket and the mounting portion). Correspondingly, the relative positions of any two positions on the base (such as the two opposite ends of the base) will not be changed. For example, in an embodiment in which both the first optical element and the second optical element are connected to the base, the portion on the base connected to the first optical element and the portion connected to the second optical element will not change due to the first assembly structure connecting the mounting frame and the base. This ensures that the first optical element and the second optical element have a certain relative position relationship and do not affect the optical path between the first optical element and the second optical element. Similarly, in an embodiment in which both the first optical element and the second optical element are connected to the main bracket, the first optical element and the second optical element have a certain relative position relationship and do not affect the optical path between the first optical element and the second optical element.

[0006] In combination with the first aspect, in some achievable manners, the first buffer member includes an adhesive layer. The adhesive layer has adhesiveness and can adhere to the main support and the base, thereby preventing the main support and the base from moving relative to each other and buffering the interaction force between the main support and the base.

[0007] In combination with the first aspect, in some achievable manners, the first buffer is disposed around the assembly rod and connected to the assembly rod. Thus, relative displacement of the assembly rod, the main bracket and the base can be avoided, and loosening of the three can be avoided. In addition, the first buffer is bonded to the assembly rod, the main bracket and the base, so that the assembly rod is radially limited, and loosening and falling off of the assembly rod can be prevented.

[0008] In combination with the first aspect, in some achievable manners, the second buffer member includes an adhesive layer. The adhesive layer can adhere the main support and the pressure plate to prevent the main support and the pressure plate from moving while buffering the interaction force between the main support and the pressure plate.

[0009] In combination with the first aspect, in some practicable manners, the second buffer member is disposed around the assembly rod and connected to the assembly rod, thereby preventing the assembly rod, the main bracket and the pressure plate from being displaced and loosened.

[0010] In combination with the first aspect, in some achievable embodiments, the first assembly structure further includes a third buffer member, and along the radial direction of the assembly rod, a second gap is provided between the assembly rod and the main support, and the third buffer member is located in the second gap.

[0011] In combination with the first aspect, in some achievable manners, the first buffer, the second buffer and the third buffer are connected to form an integrally formed part. In this way, the interaction force between the assembly rod and the main support along the radial direction of the assembly rod can be buffered by the third buffer. This prevents the force of the assembly rod from being transmitted to the main support in the radial direction of the assembly rod. It can also prevent the force of the main support from being transmitted to the assembly rod in the radial direction of the assembly rod.

[0012] In combination with the first aspect, in some achievable methods, the surface of the mounting portion away from the main support includes a first plane, and the surface of the base close to the mounting portion includes a second plane, and the first plane is in contact with the second plane. The directions of the forces acting on each position on the first plane and the base are the same and are perpendicular to the first plane. The directions of the interaction forces between each point on the mounting portion and the base are made the same, so as to avoid warping of the mounting portion or the base due to different directions of the forces acting on each point, thereby avoiding the warping from affecting the relative position of other parts of the mounting portion and the main support. The relative position between the first optical element and the second optical element is prevented from being affected by the warping. In addition, compared with curved surfaces that are in contact with each other, the first plane and the second plane are simpler in preparation process and have lower cost.

[0013] In conjunction with the first aspect, in some achievable ways, the assembly assembly further comprises: a threaded member, through which the mounting portion and the base are connected. Thus, the threaded member can realize the connection between the mounting portion and the base. The connection method is simple, and the threaded member can realize the detachable connection between the mounting portion and the base. It is convenient to replace the base and the mounting bracket. Exemplarily, the threaded member can be a bolt or a screw.

[0014] In combination with the first aspect, in some achievable manners, the assembly assembly further includes a second assembly structure, and the mounting portion and the base are connected via the second assembly structure. The second assembly structure can realize the positioning of the mounting portion and the base.

[0015] In combination with the first aspect, in some achievable ways, the second assembly structure includes an assembly rod, a first buffer, a second buffer, and a pressure plate. The pressure plate is located on a side of the mounting portion away from the base, the first buffer is located in the first gap, and the second buffer is located between the pressure plate and the mounting portion; the assembly rod passes through the mounting portion and is connected to the pressure plate at one end and to the base at the other end. Thus, the assembly rod connects the mounting portion and the base. The first buffer and the second buffer can buffer the interaction force between the mounting portion and the base, and reduce the deformation of the mounting portion and the base.

[0016] In conjunction with the first aspect, in some achievable manners, the pressing plate is connected to the assembly rod as an integrally formed part. During the process of installing the assembly component, the relative position of the pressing plate and the assembly rod will not move. The relative position relationship between the pressing plate and the assembly rod will not be affected by the assembly accuracy. The loose connection between the pressing plate and the assembly rod can be prevented from affecting the relative position of the first optical element and the second optical element.

[0017] In combination with the first aspect, in some achievable manners, the base is provided with a stepped hole, the assembly rod comprises a first section and a second section connected to each other, the diameter of the first section is larger than the diameter of the second section, the end of the first section away from the second section is connected to the pressing plate, and the end of the first section away from the pressing plate and the second section are both located in the stepped hole and connected to the stepped hole. Thus, the stepped hole has a pre-positioning effect on the assembly rod, so as to avoid the assembly rod from shifting during the connection process between the base and the assembly rod.

[0018] In combination with the first aspect, in some achievable ways, the assembly component includes a plurality of the mounting parts, and the plurality of the mounting parts are arranged at intervals. In this way, the plurality of mounting parts can increase the stress points, so that the stress of the main bracket and the base is more uniform, and deformation is avoided.

[0019] In conjunction with the first aspect, in some achievable ways, the assembly assembly includes a plurality of the first assembly structures, and the plurality of the first assembly structures are arranged at intervals. The plurality of first assembly structures can increase the stress points, so that the stress of the main bracket and the base is more uniform, and deformation is avoided.

[0020] In the second aspect, an embodiment of the present application provides a lens module, which includes a first optical element, a second optical element and any assembly component provided in the first aspect. The second optical element is spaced apart from the first optical element; the first optical element and the second optical element are both connected to the base. Alternatively, the first optical element and the second optical element are both connected to the main bracket. Since the mounting frame and the base in the assembly component do not change the relative position of any two positions on the mounting frame (such as the end of the main bracket and the mounting portion). Correspondingly, the relative position of any two positions on the base (such as the opposite ends of the base) will not be changed. The first optical element and the second optical element, both connected to the base, have a determined relative position relationship, and do not affect the optical path between the first optical element and the second optical element. The first optical element and the second optical element, both connected to the main bracket, have a determined relative position relationship, and do not affect the optical path between the first optical element and the second optical element.

[0021] In combination with the second aspect, in some achievable embodiments, the lens module further includes: a first support member, through which the first optical element is connected to the main support, and the first support member is closer to the edge of the main support relative to the mounting portion. If the first support member is farther away from the edge of the main support relative to the mounting portion, a cantilever structure is formed on the main support between the first support member and the mounting portion. In an example in which the weight of the first optical element is large, the weight of the first optical element will cause the aforementioned cantilever structure to bend, affecting the relative position of the first support member and the second support member. Obviously, the first support member is closer to the edge of the main support relative to the mounting portion. The existence of the aforementioned cantilever structure is avoided, and the deformation of the main support caused by the cantilever structure is effectively improved. Ensure that the relative position of the first support member and the second support member does not change.

[0022] In conjunction with the second aspect, in some achievable ways, the lens module further comprises: a second support member, through which the second optical element is connected to the main support, and the second support member is closer to the edge of the main support relative to the assembly rod. Similar to the aforementioned first support member being closer to the edge of the main support relative to the mounting portion. This can avoid the second support member from being connected to the cantilever structure. Ensure that the relative positions of the first support member and the second support member do not change.

[0023] In conjunction with the second aspect, in some achievable manners, the first optical element includes a first light-reflecting element, the second light-reflecting element includes a second light-reflecting element, the first light-reflecting element is used to reflect incident light to the second light-reflecting element, and the second light-reflecting element is used to reflect light from the first light-reflecting element. The first light element and the second light element can change the propagation direction of the light path.

[0024] In conjunction with the second aspect, in some achievable ways, the optical axis of the first reflective element is parallel to the optical axis of the second reflective element. The second optical element has almost no shielding on the area with high light intensity in the light beam, which can improve the module efficiency. In other embodiments, the optical axis of the first optical element and the optical axis of the second optical element can overlap.

[0025] In a third aspect, an embodiment of the present application provides an optical communication terminal. The optical communication terminal includes: a signal processor and any lens module provided in the second aspect of the present application, and the signal processor is used to receive an optical signal from the lens module. Since the assembly accuracy of the lens module is relatively high, it provides a basis for the accuracy of the optical path. Then, the optical signal transmission of the optical communication terminal is guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0037] In the following, the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0038] In addition, in the present application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to the changes in the orientation of the components in the drawings.

[0039] Figure 1a A schematic diagram of a satellite communication link. Figure 1a In the communication, satellite A can transmit an optical signal carrying information to satellite B, and satellite B receives and collects the optical signal. Similarly, satellite B can also transmit an optical signal carrying information to satellite A, and satellite A receives and collects the optical signal, thus realizing communication between satellite A and satellite B.

[0040] Taking satellite A transmitting a signal to satellite B as an example, the optical communication module on satellite A sends the optical signal carrying information to satellite B through the optical communication terminal. The same is true for satellite B transmitting a signal to satellite A.

[0041] Figure 1b is a schematic diagram of an optical communication terminal. Figure 1bThe optical communication terminal includes a lens module 200 and a signal processor, and the signal processor receives a signal from the lens module. For example, when the lens module receives an optical signal, the lens module transmits the signal to the signal processor for processing. Since the optical path is reversible, the optical signal emitted by the signal processor can also be transmitted to the lens module, and the optical signal is transmitted to other components through the lens module. It can be understood that the application scenarios of the optical communication terminal provided in the embodiment of the present application are not limited. For example, it can be used in ATP systems, satellite antennas or other precision adjustment systems, etc. Alternatively, in some embodiments, the optical communication terminal provided in the embodiment of the present application can be used in communications between satellites and the earth, etc.

[0042] Figure 2 This is a schematic diagram of the structure of a lens module 200 provided in an embodiment of the present application. Figure 2 The lens module 200 includes a first optical element 210, a second optical element 220 and an assembly component 100, and the first optical element 210 and the second optical element 220 are both connected to the assembly component 100. It can be ensured that the relative position of the first optical element 210 and the second optical element 220 does not change.

[0043] Figure 3 Schematic diagram of the structure of lens assembly 01 in the related art. Figure 3 The lens assembly 01 includes a fixing seat 02, a primary mirror 03, a secondary mirror 04 and a base 05. The primary mirror 03 and the secondary mirror 04 are arranged at intervals, the primary mirror 03 is connected to one end of the fixing seat 02, and the base 05 is connected to the fixing seat 02. The secondary mirror 04 is connected to an end of the base 05 away from the fixing seat 02. Figure 3 In the example shown in FIG. 1 , there is an assembly error in the process of connecting the base 05 and the fixing seat 02, which will affect the relative position between the primary mirror 03 and the secondary mirror 04. This will cause a large deviation between the actual relative position of the primary mirror 03 and the secondary mirror 04 and the designed relative position. This deviation will cause the light propagation path between the primary mirror 03 and the secondary mirror 04 (such as Figure 3 There is an offset (dashed arrow in the middle), which affects the optical signal propagating between the primary mirror 03 and the secondary mirror 04.

[0044] Therefore, the lens module 200 provided in the embodiment of the present application can reduce the position deviation between the first optical element 210 and the second optical element 220 , thereby improving the reliability of the lens module 200 .

[0045] Figure 2 In the embodiment, the assembly component 100 includes a mounting frame 110 , a base 120 and a first assembly structure 130 . Figure 2 In the embodiment, the first optical element 210 and the second optical element 220 are both connected to the mounting frame 110 . Alternatively, in other embodiments, the first optical element 210 and the second optical element 220 are both connected to the base 120 .

[0046] The mounting frame 110 includes a main support 111 and a mounting portion 112, and the main support 111 is connected to the mounting portion 112. The base 120 is connected to the mounting portion 112, and a first gap 101 is formed between the base 120 and the main support 111. The first assembly structure 130 includes an assembly rod 133, a first buffer 131, a second buffer 132, and a pressing plate 134. The first buffer 131 is located in the first gap 101. The pressing plate 134 is located on a side of the main support 111 away from the base 120, and the second buffer 132 is located between the main support 111 and the pressing plate 134. In other words, the second buffer 132 and the pressing plate 134 are sequentially stacked in a direction away from the main support 111, and the second buffer 132 and the pressing plate 134 are both located on a side of the main support 111 away from the base 120. One end of the assembly rod 133 is connected to the pressing plate 134, and the other end of the assembly rod 133 is connected to the base 120.

[0047] Because the mounting portion 112 is connected to the base 120, the acting force between the mounting frame 110 and the base 120 is transmitted through the mounting portion 112, so that the base 120 and the mounting frame 110 support each other, and the mounting portion 112 and the base 120 have a determined relative positional relationship. One end of the assembly rod 133 is connected to the pressure plate 134, and the other end of the assembly rod 133 is connected to the base 120. Therefore, the assembly rod 133 connects the main bracket 111 and the base 120. There are at least two force points between the mounting frame 110 and the base 120, one from the mounting portion 112 and the other from the assembly rod 133. Compared with a cantilever structure with one force point, the two force points make the force between the mounting frame 110 and the base 120 more uniform. Avoid bending of the end of the main bracket 111 away from the mounting portion 112 or the end of the base 120 away from the mounting portion 112 due to internal stress. Because there is a first gap 101 between the base 120 and the main support 111, and the first buffer 131 is located in the first gap 101, the first buffer 131 can buffer the interaction force between the base 120 and the main support 111. The bending of the base 120 and the main support 111 caused by the interaction force between the base 120 and the main support 111 is reduced, and the change in the relative position of the base 120 and the main support 111 is reduced. Similarly, the second buffer 132 located between the main support 111 and the pressure plate 134 can buffer the force between the main support 111 and the pressure plate 134. Reducing the interaction force between the main support 111 and the pressure plate 134 causes the relative position of the main support 111 and the pressure plate 134 to change. Then, the first buffer 131 and the second buffer 132 effectively relieve the stress between the main support 111 and the base 120, causing the main support 111 and the base 120 to bend. During the process of assembling the mounting frame 110 and the base 120, the first assembly structure 130 connecting the mounting frame 110 and the base 120 does not change the relative positions of any two positions on the mounting frame 110 (such as the end of the main bracket 111 and the mounting portion 112). Correspondingly, the relative positions of any two positions on the base 120 (such as the two opposite ends of the base 120) will not be changed. The assembly and adjustment costs are reduced, and large-scale production is easy.

[0048] For example, in the embodiment where both the first optical element 210 and the second optical element 220 are connected to the base 120, the part on the base 120 connected to the first optical element 210 and the part connected to the second optical element 220 will not change because the first assembly structure 130 connects the mounting frame 110 and the base 120. This ensures that the first optical element 210 and the second optical element 220 have a certain relative position relationship and do not affect the optical path between the first optical element 210 and the second optical element 220. Similarly, in the embodiment where both the first optical element 210 and the second optical element 220 are connected to the main bracket 111, the first optical element 210 and the second optical element 220 have a certain relative position relationship and do not affect the optical path between the first optical element 210 and the second optical element 220.

[0049] The embodiment of the present application does not limit the connection method between the mounting portion 112 and the base 120. In some embodiments, the assembly component 100 further includes a threaded member 140, and the mounting portion 112 and the base 120 are connected by the threaded member 140. In this way, the threaded member 140 can realize the connection between the mounting portion 112 and the base 120. The connection method is simple, and the threaded member 140 can realize the detachable connection between the mounting portion 112 and the base 120. It is convenient to replace the base 120 and the mounting frame 110. Exemplarily, the threaded member 140 can be a bolt or a screw.

[0050] The embodiment of the present application does not limit the number of the threaded members 140 . For example, the number of the threaded members 140 may be one, two, three or more.

[0051] Figure 2 In the embodiment, the surface of the mounting portion 112 away from the main support 111 is the first plane 103, and the surface of the base 120 close to the mounting portion 112 is the second plane 104, and the first plane 103 and the second plane 104 are in contact with each other. In this way, the direction of the force acting on each position on the first plane 103 and the base 120 is the same, and is perpendicular to the first plane 103. The direction of the interaction force between each point on the mounting portion 112 and the base 120 is made the same, so as to avoid the warping of the mounting portion 112 or the base 120 caused by the different directions of the force acting on each point, thereby avoiding the warping from affecting the relative position change of other parts on the mounting portion 112 and the main support 111. The relative position between the first optical element 210 and the second optical element 220 is prevented from being affected by the warping. In addition, compared with the curved surfaces that are in contact with each other, the first plane 103 and the second plane 104 are simpler in preparation process and have lower cost.

[0052] Figure 2 In the embodiment, the first plane 103 is parallel to the extension direction of the main support 111, and the second plane 104 is parallel to the first plane 103. It is understood that in other embodiments, the extension direction of the first plane 103 and the main support 111 may not be parallel. For example, the angle between the first plane 103 and the extension direction of the main support 111 may be, for example, 10° to 50°.

[0053] Figure 2In the embodiment, there are two mounting parts 112, and the two mounting parts 112 are arranged at intervals. In this way, the points of force of the mounting frame 110 and the base 120 can be increased, so that the force of the mounting frame 110 and the base 120 is more uniform, and the warping of the mounting frame 110 and the base 120 due to uneven force is avoided. In addition, the two mounting parts 112 are arranged at intervals, and the two first planes 103 are arranged at intervals. There is no restriction on the roughness of the area between the two first planes 103, and only the plane accuracy of the two first planes 103 can be guaranteed, thereby reducing the cost of polishing the plane and reducing the cost of the mounting frame 110. It can be understood that in other embodiments of the present application, the number of mounting parts 112 can be one, three or more.

[0054] In an embodiment of the present application, the second plane 104 and the first plane 103 have the same shape. In this way, the base 120 only needs to ensure the plane accuracy of the area with the same area as the first plane 103, so that the second plane 104 and the first plane 103 fit together, reducing the cost of polishing the plane. Exemplarily, there is a first gap 101 between the main support 111 and the base 120, and the roughness of the side of the main support 111 close to the first gap 101 is not restricted, and the roughness of the side of the base 120 close to the first gap 101 is also not restricted. The manufacturing cost can be reduced. Because of the existence of the first gap 101, the positional relationship between the surface of the main support 111 close to the first gap 101 and the surface of the base 120 close to the first gap 101 is not restricted. Reduce the cost of assembly and adjustment and improve the efficiency of assembly and adjustment.

[0055] In some embodiments, the roughness of the first plane 103 is at the μm level, and the roughness of the second plane 104 is at the μm level. The accuracy of the first plane 103 and the second plane 104 can be guaranteed.

[0056] In the embodiment of the present application, there is no limitation on the distance between the mounting portion 112 and the main bracket 111. For example, the distance from the first plane 103 to the surface of the main bracket 111 facing the first gap 101 is 0.1 mm (millimeter)-0.5 mm, for example, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm or 0.5 mm.

[0057] As described above, the first buffer member 131 is located in the first gap 101. The embodiment of the present application does not limit the relative sizes of the first buffer member 131 and the first gap 101. Figure 2 In the example, the first buffer 131 fills part of the space of the first gap 101, which can ensure that the first buffer 131 buffers the interaction force between the main bracket 111 and the base 120 while reducing the amount of the first buffer 131, thereby reducing the material cost and the weight of the assembly 100. In other embodiments, the first buffer 131 can fill the entire space of the first gap 101.

[0058] The embodiment of the present application does not limit the structure of the first buffer 131. In some embodiments, the first buffer 131 includes an adhesive layer, which is sticky and can adhere to the main bracket 111 and the base 120. In addition, the main bracket 111 and the base 120 are bonded by the adhesive layer to prevent the main bracket 111 and the base 120 from moving relative to each other while buffering the interaction force between the main bracket 111 and the base 120. In other embodiments, the first buffer 131 can be a rubber gasket or foam cotton.

[0059] In the embodiment of the present application, the number of the first buffer member 131 may be one, two or more. In the embodiment where there are a plurality of first buffer members 131, the plurality of first buffer members 131 are arranged at intervals.

[0060] Figure 2 In the embodiment, the first buffer member 131 is arranged around the assembly rod 133. In the embodiment where the first buffer member 131 is a glue layer, the assembly rod 133, the main bracket 111 and the base 120 are all connected to the glue layer. The assembly rod 133, the main bracket 111 and the base 120 are prevented from relative displacement and loosening. In addition, the first buffer member 131 is bonded to the assembly rod 133, the main bracket 111 and the base 120. The assembly rod 133 is radially limited. The assembly rod 133 is prevented from loosening and falling off.

[0061] It is understandable that in other embodiments, the first buffer 131 and the assembly rod 133 may be spaced apart, and there may be a gap between the first buffer 131 and the assembly rod 133. Similarly, the first buffer 131 may also buffer the interaction force between the main bracket 111 and the base 120.

[0062] The embodiment of the present application does not limit the structure of the second buffer 132. In some embodiments, the second buffer 132 includes an adhesive layer, which can adhere to the main bracket 111 and the pressure plate 134. The interaction force between the main bracket 111 and the pressure plate 134 is buffered while preventing the main bracket 111 and the pressure plate 134 from moving. In other embodiments, the second buffer 132 can be a rubber gasket or foam cotton.

[0063] In the embodiment of the present application, the number of the second buffer member 132 may be one, two or more. In the embodiment where there are a plurality of second buffer members 132, the plurality of second buffer members 132 are arranged at intervals.

[0064] Figure 2In the embodiment, the second buffer member 132 is arranged around the assembly rod 133. In the embodiment where the second buffer member 132 is an adhesive layer, the assembly rod 133, the main bracket 111 and the pressure plate 134 are all bonded to the adhesive layer. Avoid displacement of the assembly rod 133, the main bracket 111 and the pressure plate 134, and prevent the three from loosening. It can be understood that in the case where the second buffer member 132 is arranged between the main bracket 111 and the pressure plate 134, the second buffer member 132 and the assembly rod 133 can be arranged at intervals. In other words, there can be a gap between the second buffer member 132 and the assembly rod 133, which can also buffer the interaction force between the main bracket 111 and the pressure plate 134.

[0065] The embodiment of the present application does not limit the shape of the assembly rod 133. For example, the assembly rod 133 may be cylindrical or prismatic.

[0066] The present application embodiment does not limit the structure of the pressing plate 134. In some embodiments, the pressing plate 134 is a circular plate. The interaction force between the pressing plate 134 and the second buffer member 132 is more evenly distributed. In other embodiments, the pressing plate 134 can be a square, oval or irregularly shaped plate structure.

[0067] In some embodiments, the surface of the pressing plate 134 facing the main support 111 and the surface of the main support 111 facing the pressing plate 134 are parallel to each other. In this way, the distance between each part of the pressing plate 134 and the main support 111 is equal. When the second buffer 132 is compressed by the main support 111 and the pressing plate 134, the forces applied to each position of the second buffer 132 are equal. It is prevented that the forces applied to each position of the second buffer 132 are unequal and the deformation amounts are unequal. It is prevented that the deformation of the pressing plate 134 affects the relative position relationship between the first optical element 210 and the second optical element 220.

[0068] The embodiment of the present application does not limit the connection method of the pressing plate 134 and the assembly rod 133. Exemplarily, the pressing plate 134 and the assembly rod 133 are connected as an integrally formed part. In this way, during the installation of the assembly component 100, the relative position of the pressing plate 134 and the assembly rod 133 will not move. The relative position relationship between the pressing plate 134 and the assembly rod 133 will not be affected by the assembly accuracy. It can be avoided that the loose connection between the pressing plate 134 and the assembly rod 133 affects the relative position of the first optical element 210 and the second optical element 220.

[0069] Exemplarily, the pressure plate 134 and the assembly rod 133 are connected by screws, such as shoulder screws.

[0070] In other embodiments of the present application, the pressing plate 134 and the assembly rod 133 may be connected by welding. Alternatively, in other embodiments, the pressing plate 134 and the assembly rod 133 may be connected by a detachable connection such as a screw connection or a clamp connection.

[0071] The embodiment of the present application does not limit the connection method between the assembly rod 133 and the base 120. Exemplarily, the assembly rod 133 and the base 120 are screwed to ensure the stability of the assembly rod 133 and the base 120. For example, an external thread is provided on the assembly rod 133, and an internal thread is provided on the base 120. The internal thread and the external thread are threadedly connected to connect the assembly rod 133 and the base 120. In some embodiments, the assembly rod 133 and the base 120 can be connected by a glue layer. Alternatively, in other embodiments, the assembly rod 133 and the base 120 are interference fit, etc.

[0072] Figure 4 This is a schematic diagram of the exploded structure of a base 120, an assembly rod 133 and a pressure plate 134 provided in an embodiment of the present application. Figure 4 The base 120 is provided with a stepped hole 121, and the assembly rod 133 includes a first section 135 and a second section 136 connected to each other. The diameter of the first section 135 is greater than the diameter of the second section 136, and one end of the first section 135 away from the second section 136 is connected to the pressing plate 134. The end of the first section 135 away from the pressing plate 134 and the second section 136 are both located in the stepped hole 121 and connected to the stepped hole 121.

[0073] In this way, during the connection process, one end of the first section 135 and the second section 136 extend into the stepped hole 121, and the stepped hole 121 has a pre-positioning effect on the assembly rod 133. Avoid the assembly rod 133 from being offset during the connection process between the base 120 and the assembly rod 133. During the process of screwing the assembly rod 133 and the base 120, an internal thread is provided in the stepped hole 121. The step surface in the stepped hole 121 and the end surface of the first section 135 away from the pressure plate 134 fit each other. The force on the step surface and the first section 135 is more uniform, reducing the change in the relative position of the step surface and the assembly rod 133. The assembly rod 133 and the base 120 have a determined relative position, thereby avoiding the connection between the assembly rod 133 and the base 120 affecting the relative position of the first optical element 210 and the second optical element 220.

[0074] Exemplarily, the assembly order of the assembly rod 133 and the base 120 is to first extend the assembly rod 133 into the stepped hole 121 to connect with the stepped hole 121, and then connect the mounting portion 112 and the base 120. Glue is poured into the stepped hole, and the glue is heated and melted to solidify around the assembly rod 133 to form a glue layer.

[0075] Exemplarily, in order to ensure machining accuracy, the difference (φ2-φ3) between the inner diameter φ2 of the portion where the stepped hole 121 and the first section 135 are connected and the outer diameter φ3 of the first section 135 of the assembly rod 133 is less than 10 μm. For example, it can be 0.5 μm, 1 μm, 2 μm, 3 μm, 4 μm, 5 μm, 6 μm, 7 μm, 8 μm, 9 μm or 10 μm, etc.

[0076] In other embodiments, the base 120 may not be provided with the stepped hole 121. For example, the base 120 is provided with an assembly hole connected to the second section 136. The diameter of the assembly hole is uniform.

[0077] As mentioned above, the assembly rod 133 passes through the main bracket 111 and one end is connected to the pressing plate 134. Obviously, the main bracket 111 is also provided with a mounting hole, and the assembly rod 133 is located in the mounting hole.

[0078] Figure 5 This is a schematic diagram of the exploded structure of the first assembly structure 130 and the main bracket 111 provided in the embodiment of the present application. Figure 5 The main bracket 111 is provided with a mounting hole 113. The mounting hole 113 penetrates the main bracket 111, and one end of the assembly rod 133 passes through the mounting hole 113 and is connected to the pressing plate 134, and the other end of the assembly rod 133 is connected to the main base 120.

[0079] The embodiment of the present application does not limit the shape of the mounting hole 113. For example, the mounting hole 113 can be a through hole with a uniform diameter, which is easy to process. The second buffer 132 and the pressing plate 134 are both located outside the mounting hole 113.

[0080] Exemplarily, in order to ensure machining accuracy, the difference (φ1-φ3) between the inner diameter φ1 of the mounting hole 113 and the outer diameter φ3 of the first section 135 of the assembly rod 133 is less than 10 μm, for example, 0.5 μm, 1 μm, 2 μm, 3 μm, 4 μm, 5 μm, 6 μm, 7 μm, 8 μm, 9 μm or 10 μm.

[0081] The embodiment of the present application does not limit the thickness of the main bracket 111, and can be set according to the size of the first section 135 of the assembly rod 133 and the size of the mounting portion 112. For example,

[0082] The main bracket 111 and the mounting portion 112 (such as Figure 2 The difference between the sum of the dimensions of the first section 135 along the extension direction of the assembly rod 133 (as shown) and the dimension of the first section 135 is 0.05 mm to 0.5 mm. For example, it can be 0.05 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm or 0.5 mm. The dimension of the mounting portion 112 along the extension direction of the assembly rod 133 is the dimension of the first plane 103 (as shown). Figure 2 The distance from the surface of the main support 111 facing the first gap 101 (as shown).

[0083] The embodiment of the present application does not limit the shape of the mounting hole 113. For example, the mounting hole 113 can be a T-shaped hole. The second buffer 132 and the pressure plate 134 can both be located in the mounting hole 113. When the assembly rod 133 and the pressure plate 134 are in a connected state, the end of the assembly rod 133 away from the base 120 is also located in the mounting hole 113. In this way, the end face of the first assembly structure 130 does not protrude from the surface of the main bracket 111. The space occupied by the first assembly structure 130 is reduced. Other components (such as the first optical element 210 and the second optical element 220) can also be avoided. In addition, in an embodiment in which the second buffer 132 is an adhesive layer, the second buffer 132 is located in the mounting hole 113, and the surrounding wall of the mounting hole 113 limits the overflow of the second buffer 132 to prevent the overflow of the second buffer 132 from affecting other components.

[0084] Figure 5 In the embodiment, along the radial direction of the assembly rod 133, there is a second gap 102 between the assembly rod 133 and the main support 111. In other words, along the radial direction of the assembly rod 133, the assembly rod 133 and the main support 111 are not in contact. The first assembly structure 130 also includes a third buffer 137. The third buffer 137 is located in the second gap 102. In this way, along the radial direction of the assembly rod 133, the interaction force between the assembly rod 133 and the main support 111 can be buffered by the third buffer 137. It is prevented that the force of the assembly rod 133 is transmitted to the main support 111 through the radial direction of the assembly rod 133. It is also prevented that the force of the main support 111 is transmitted to the assembly rod 133 through the radial direction of the assembly rod 133.

[0085] The embodiment of the present application does not limit the structure of the third buffer member 137. For example, the third buffer member 137 may be a glue layer. The adhesive property of the glue layer may prevent the assembly rod 133 and the main bracket 111 from relative displacement. Alternatively, in other embodiments, the third buffer member 137 may be a rubber sheet or a sponge.

[0086] In the embodiment where the first buffer 131, the second buffer 132 and the third buffer 137 are made of the same material, the first buffer 131, the second buffer 132 and the third buffer 137 are connected as an integrally formed part for easy assembly. For example, in the embodiment where the first buffer 131, the second buffer 132 and the third buffer 137 are all glue layers, the first buffer 131, the second buffer 132 and the third buffer 137 can be formed together by glue pouring or glue coating.

[0087] In some embodiments, the third buffer member 137 is disposed around the assembly rod 133. In this way, the assembly rod 133 is in contact with the third buffer member 137 around all four sides. In other embodiments, the third buffer member 137 may only be in contact with a portion of the circumference of the assembly rod 133. This can also buffer the interaction force between the assembly rod 133 and the main bracket 111.

[0088] In the embodiment where the mounting hole 113 is a T-shaped hole, the third buffer member 137 is located in the mounting hole 113. The T-shaped hole can prevent the third buffer member 137 from overflowing.

[0089] It is understandable that, in the embodiment of the present application, the third buffer member 137 is not necessary, and the first assembly structure 130 may not be provided with the third buffer member 137 .

[0090] The assembly rod 133 connects the base 120 and the pressure plate 134. The pressure plate 134 fastens the main bracket 111 through the second buffer 132. The base 120 fastens the main bracket 111 through the second buffer 132, so that the pressure plate 134, the main bracket 111 and the base 120 are relatively fixed. In addition, because the first buffer 131, the second buffer 132 and the third buffer 137 can buffer the force. Therefore, it can be avoided that the main bracket 111 and the base 120 are connected by the assembly rod 133, causing the main bracket 111 and the base 120 to be deformed. In other words, the first assembly structure 130 connects the base 120 and the main bracket 111 while greatly improving the deformation of the base 120 and the main bracket 111 caused by the connection. Then, any two positions on the base 120 do not change due to the connection between the base 120 and the mounting frame 110. If the aforementioned two positions are connected to the first optical element 210 and the second optical element 220 respectively, the relative positions of the first optical element 210 and the second optical element 220 do not change due to the connection between the base 120 and the mounting frame 110. Similarly, any two positions on the main support 111 do not change due to the connection between the base 120 and the mounting frame 110. If the aforementioned two positions are connected to the first optical element 210 and the second optical element 220 respectively, the relative positions of the first optical element 210 and the second optical element 220 do not change due to the connection between the base 120 and the mounting frame 110.

[0091] Please return to Figure 2 As shown, the first optical element 210 and the second optical element 220 are both connected to the main bracket 111. The first optical element 210 and the second optical element 220 are arranged at intervals. The embodiment of the present application does not limit the phase position of the first optical element 210 and the second optical element 220. It can be set according to the design of the optical path in the lens module 200.

[0092] The embodiment of the present application does not limit the shape of the main support 111. The shape of the main support 111 can be set according to the phase position of the first optical element 210 and the second optical element 220. Figure 2 In the embodiment, the main support 111 is a U-shaped frame, and the U-shaped frame includes a first arm 114, a second arm 115 and a crossbeam 116. The first arm 114 and the second arm 115 are connected to opposite ends of the crossbeam 116 respectively.

[0093] Figure 2 In the embodiment, the first optical element 210 is connected to the first arm 114. The second optical element 220 is connected to the second arm 115. The first assembly structure 130 is connected to the crossbeam 116. The mounting portion 112 and the first assembly structure 130 are both connected to the crossbeam 116. The rigidity of the assembly component 100 can be ensured while reducing the size of the assembly component 100. The space between the first optical element 210 and the second optical element 220 can be fully utilized. Figure 2 Taking the orientation in the figure as an example, the height of the assembly component 100 can be reduced to fully utilize the horizontal space. The layout space is reduced. The U-shaped frame does not block the optical path of the first optical element 210 and the second optical element 220. The optical performance is good.

[0094] The embodiment of the present application does not limit the connection mode between the first optical element 210 and the first arm 114 and the connection mode between the second optical element 220 and the second arm 115. Exemplarily, the lens module 200 further includes a first support member 230 and a second support member 240. The first optical element 210 and the first arm 114 are connected via the first support member 230. The second optical element 220 and the second arm 115 are connected via the second support member 240.

[0095] Exemplarily, the first support member 230 and the first arm 114 are welded or connected to form an integral part. The second support member 240 and the second arm 115 are welded or connected to form an integral part. As mentioned above, the connection between the mounting frame 110 and the base 120 does not affect the relative positional relationship between any two areas on the mounting frame 110. Obviously, the relative positional relationship between the first support member 230 and the second support member 240 will not change due to the connection between the mounting frame 110 and the base 120.

[0096] Figure 2In the example, the first support member 230 is closer to the edge of the main support 111 relative to the mounting portion 112. If the first support member 230 is farther away from the edge of the main support 111 relative to the mounting portion 112, a cantilever structure is formed on the main support 111 between the first support member 230 and the mounting portion 112. In the example where the weight of the first optical element 210 is large, the weight of the first optical element 210 will cause the aforementioned cantilever structure to bend, affecting the relative position of the first support member 230 and the second support member 240. Obviously, the first support member 230 is closer to the edge of the main support 111 relative to the mounting portion 112. The existence of the aforementioned cantilever structure is avoided, and the deformation of the main support 111 caused by the cantilever structure is effectively improved. Ensure that the relative position of the first support member 230 and the second support member 240 does not change.

[0097] It is understandable that in the example where the weight of the first optical element 210 is relatively small, the weight of the first optical element 210 is not likely to cause deformation of the main support 111. The first support member 230 may be further away from the edge of the main support 111 relative to the mounting portion 112.

[0098] Figure 2 In the example of FIG. 1 , the second support member 240 is closer to the edge of the main support 111 relative to the assembly rod 133. This is similar to the above-mentioned first support member 230 being closer to the edge of the main support 111 relative to the mounting portion 112. This can avoid the second support member 240 from being connected to the cantilever structure. It is ensured that the relative positions of the first support member 230 and the second support member 240 do not change.

[0099] It can be understood that in the example where the weight of the second optical element 220 is small, the weight of the second optical element 220 is not easy to cause the main bracket 111 to deform. The second support member 240 is farther away from the edge of the main bracket 111 relative to the assembly rod 133. The embodiment of the present application does not limit the structure of the first optical element 210 and the second optical element 220. In some embodiments, the weight of the second optical element 220 is greater than the weight of the first optical element 210. In this way, the first optical element 210 is closer to the mounting portion 112 relative to the second optical element 220. Since the mounting portion 112 and the base 120 are in surface contact. The support strength of the mounting portion 112 and the base 120 can be increased by increasing the contact area. To support the second optical element 220 with a larger weight. Accordingly, the second optical element 220 is closer to the first assembly structure 130 relative to the first optical element 210. The support strength of the assembly rod 133 can be relatively small, which alleviates the force transmitted to the first buffer 131 and the second buffer 132. The deformation of the main support 111 in the vicinity of the assembly rod 133 is further reduced. The relative positions of the first support member 230 and the second support member 240 are ensured not to change.

[0100] The embodiment of the present application does not limit the number of the first assembly structures 130 in the lens module 200. For example, the number of the first assembly structures 130 can be one, two, or more. In an embodiment where there are multiple first assembly structures 130, the multiple first assembly structures 130 can be arranged at intervals around the circumference of the second support member 240. Similarly, in an embodiment where there are multiple mounting portions 112, the multiple mounting portions 112 can be arranged at intervals around the circumference of the first support member 230.

[0101] Figure 2 In the example of FIG. 1 , the first assembly structure 130 and the mounting portion 112 are both connected to the crossbeam 116 . The first assembly structure 130 and the mounting portion 112 are located at opposite ends of the crossbeam 116 , respectively. Figure 6 This is a schematic structural diagram of another lens module 200 provided in an embodiment of the present application. Figure 6 In the embodiment, the first assembly structure 130 is connected to the first arm 114. The mounting portion 112 is connected to the crossbeam 116. In this way, the mounting frame 110 and the base 120 are connected via the first assembly structure 130 and the mounting portion 112. Similarly, deformation during the connection between the mounting frame 110 and the base 120 can be avoided. The relative position of the first optical element 210 and the second optical element 220 is prevented from being offset.

[0102] and Figure 6 Similarly to the example shown, in some embodiments, the mounting portion 112 may also be connected to the second arm 115. This will not be described in detail here.

[0103] As mentioned above, the structures of the first optical element 210 and the second optical element 220 are set according to the optical path design. For example, the first optical element 210 can be a reflective element, a light-transmitting element, or a light-splitting element. Similarly, the second optical element 220 can be a reflective element, a light-transmitting element, or a light-splitting element.

[0104] Figure 2 In the example of , the first light element 210 includes a first light reflecting element, and the second light element 220 includes a second light reflecting element. Figure 2 As shown by the middle dotted line, the incident light is projected onto the second reflective element and then reflected by the second reflective element, the light reflected by the second reflective element is projected onto the first reflective element, and the first reflective element reflects the light from the second reflective element and then emits. The first reflective element and the second reflective element can change the propagation direction of the light path.

[0105] Figure 2 In the example, the optical axis of the first optical element 210 is parallel to the optical axis of the second optical element 220. The second optical element 220 has almost no shielding on the area with high light intensity in the light beam, which can improve the module efficiency. In other embodiments, the optical axis of the first optical element 210 and the optical axis of the second optical element 220 can coincide.

[0106] The embodiment of the present application does not limit the structure of the reflective element. For example, the reflective element may be a reflective sheet, or the reflective element includes a lens and a reflective film connected to each other.

[0107] It is understandable that in other embodiments, the optical paths of the first optical element 210 and the second optical element 220 may be other paths, which is not limited in the present embodiment.

[0108] In addition, in some embodiments, the lens module 200 is not limited to two optical elements. In some embodiments, the lens module 200 may include three, four or more optical elements. The embodiment of the present application does not limit the optical paths of multiple optical elements.

[0109] Figure 6 In the example, the first optical element 210 and the second optical element 220 are both connected to the main support 111 . Figure 7 This is a schematic structural diagram of another lens module 200 provided in an embodiment of the present application. Figure 7 In the example of FIG. 1 , the first optical element 210 and the second optical element 220 are both connected to the base 120. For the rest of the description, please refer to Figure 6 , I will not go into details here.

[0110] The connection method between the first optical element 210 and the base 120 can refer to the connection method between the first optical element 210 and the main support 111. The connection method between the second optical element 220 and the base 120 can refer to the connection method between the second optical element 220 and the main support 111.
