Technical Field

[0001] The embodiments of the present application relate to the field of optical machinery technology, and in particular to an optical machine, a display device, and a vehicle. Background Art

[0002] Generally, the optical machine includes a housing and a lens. The housing includes a receiving cavity. The lens is arranged inside the receiving cavity and connected to the housing by bonding at the bottom and at the shoulder. The bottom end surface of the lens is bonded to the bottom wall of the receiving cavity by glue, and the two opposite end walls of the lens are bonded to the two opposite side walls of the receiving cavity by glue, so that the lens is connected to the housing. However, the reliability of the connection between the lens and the housing is low, which will reduce the optical quality. Therefore, how to improve the reliability of the connection between the lens and the housing has become a problem to be solved urgently. Summary of the invention

[0003] The embodiments of the present application provide an optical machine, a display device, and a vehicle, which can improve the reliability of the connection between the lens and the housing, thereby ensuring the position accuracy of the lens and further ensuring the optical quality.

[0004] In a first aspect, the present application provides an optical machine, comprising a housing, at least one lens and at least one adhesive. The housing comprises at least one fixing group, each fixing group corresponds to a lens, each fixing group comprises two fixing platforms arranged on opposite sides of the corresponding lens, and the two fixing platforms of each fixing group are respectively bonded to opposite ends of the corresponding lens through two adhesives. At least one fixing platform comprises a clamping space for accommodating a portion of the corresponding adhesive, and the clamping space is used to clamp the fixing platform with the corresponding adhesive.

[0005] The optical machine provided in the embodiment of the present application can increase the bonding area between the adhesive and the fixed platform by providing a clamping space for accommodating the part of the adhesive, thereby improving the bonding performance between the adhesive and the fixed platform, and further improving the reliability of the connection between the adhesive and the fixed platform. In addition, when the glue peels off, for example, when the bonding force between the adhesive and the fixed platform disappears, the connection between the adhesive and the fixed platform will not fail due to the clamping of the fixed platform and the adhesive, which can improve the reliability of the connection between the adhesive and the fixed platform. Therefore, by cooperating with the clamping space and the adhesive, the reliability of the connection between the adhesive and the fixed platform can be improved, which can not only ensure the position accuracy of the lens and thus ensure the optical quality, but also prevent the lens from shifting or falling off due to vibration, thereby ensuring the optical quality.

[0006] In a possible implementation manner, at least one clamping space is used to clamp the fixing platform and the corresponding adhesive component in the first direction.

[0007] The optical machine provided in the embodiment of the present application uses a clamping space to clamp the fixing platform and the corresponding adhesive member in the first direction, which can prevent the lens from shaking or falling off in the first direction due to vibration, so as to ensure the position accuracy of the lens. In addition, along the second direction, a fixing platform is respectively provided on the opposite sides of the lens, and the lens is respectively bonded to the two fixing platforms through two adhesive members, which can prevent the lens from shaking or falling off in the second direction due to vibration, so as to ensure the position accuracy of the lens. Therefore, by clamping the fixing platform and the corresponding adhesive member in the first direction, the position accuracy of the lens can be ensured.

[0008] In a possible implementation, at least one of the clamping spaces is a clamping slot, which includes a first slot and a second slot, wherein the first slot passes through the side wall of the fixing platform and faces the lens along the second direction, and the second slot passes through the top surface of the fixing platform along the third direction, wherein the first direction, the second direction and the third direction are perpendicular to each other.

[0009] At least one of the snap-in spaces in the optical machine provided in the embodiment of the present application is a snap-in groove, which can not only realize that the snap-in space can accommodate part of the adhesive component so as to realize the snap-in connection between the fixing platform and the corresponding adhesive component, but also reduce the difficulty of setting the snap-in space on the fixing platform. In addition, the snap-in groove will not affect the adjustment range of the lens, and the lens coupling space can be opened. In addition, the snap-in groove occupies a small space, and the use position is flexible, which is conducive to the small volume design of the product.

[0010] In a possible implementation, the engaging groove is at least one of the following grooves: a U-shaped groove, an arc groove, a semicircular groove, or a V-shaped groove. Through any of these grooves, not only can the bonding performance between the adhesive member and the fixing platform be improved, but also the fixing platform and the corresponding adhesive member can be engaged.

[0011] In a possible implementation, at least one fixing platform includes a main body portion, and along the second direction, there is a matching gap between the main body portion and the end face of the corresponding lens for accommodating part of the adhesive, and the main body portion of at least one fixing platform includes a clamping space.

[0012] A matching gap for accommodating a portion of the adhesive is provided between the fixing table and the lens in the optical machine provided in the embodiment of the present application, so that the adhesive can be bonded to the lens and the fixing table respectively. In addition, the two fixing tables can also limit the corresponding lens from shaking along the second direction to ensure the position accuracy of the lens.

[0013] In a possible implementation, at least one matching gap includes a first gap section and a second gap section. Along the second direction, the width of the first gap section is greater than the width of the second gap section. Along the third direction, the first gap section is close to the top end of the fixing platform and close to the clamping space, and the second gap section is close to the bottom end of the fixing platform.

[0014] The matching gap in the optical machine provided in the embodiment of the present application is formed by the first gap section and the second gap section, which can increase the bonding area between the fixing platform and the adhesive, thereby improving the bonding performance of the adhesive and the fixing platform, and further improving the reliability of the connection between the adhesive and the fixing platform. In addition, it can also reduce the difficulty of setting the adhesive inside the matching gap, and increase the speed of the adhesive bonding the fixing platform and the lens.

[0015] In a possible implementation, along the third direction, a depth of the at least one engaging space is equal to a height of the first gap segment.

[0016] The optical machine provided in the embodiment of the present application can increase the bonding area between the adhesive and the inner wall of the clamping space by making the depth of the clamping space equal to the height of the first gap section, thereby improving the reliability of bonding between the inner wall of the clamping space and the adhesive. In addition, the reliability of clamping between the adhesive and the fixing platform can also be improved.

[0017] In a possible implementation, at least one fixing platform includes at least one extension portion, and along the first direction, at least one of the two opposite sides of at least one lens is provided with the extension portion.

[0018] At least one of the two opposite sides of at least one lens in the optical machine provided in the embodiment of the present application is provided with an extension part, which can not only increase the bonding area between the fixing platform and the adhesive, thereby improving the reliability of the connection between the adhesive and the fixing platform, but also limit the lens in the second direction without affecting the light transmitted by the lens, thereby preventing the lens from shaking in the second direction, so as to ensure the position accuracy of the lens. In addition, during the process of dispensing glue, the extension part can also ensure that the glue enters the inside of the matching gap, so that the glue bonds the fixing platform and the lens.

[0019] In a possible implementation, at least one lens is provided with extension portions on two opposite sides thereof, and the number of the extension portions on the two opposite sides of at least one lens is the same or different.

[0020] At least one lens in the optical machine provided in the embodiment of the present application is provided with the same or different numbers of extension parts on opposite sides, which can prevent the lens from shaking or falling off along the second direction and further improve the position accuracy of the lens.

[0021] In a possible implementation, at least one lens is disposed inside the housing, and along the third direction, one end of each of the at least one lens is bonded to the inner wall of the housing, and the other end is bonded to two corresponding fixing platforms.

[0022] At least one lens in the optical machine provided in the embodiment of the present application is arranged inside the housing, which can protect the lens and prevent accidental damage to the lens. In addition, one end of the lens is bonded to the inner wall of the housing, and the other end is bonded to two corresponding fixing platforms, so that the lens is connected to the housing through the main bonding at the bottom and the auxiliary fixing at the shoulder, which can prevent the lens from vibrating or falling off due to vibration.

[0023] In a possible implementation manner, the housing is a plastic housing, and the at least one fixing platform is a plastic fixing platform.

[0024] The optical machine provided in the embodiment of the present application adopts a plastic shell in combination with a lens, which can reduce the cost of the shell and thus reduce the cost of the optical machine.

[0025] In a possible implementation, the optical machine includes a plurality of lenses, wherein: a portion of the plurality of lenses are plastic lenses and another portion are glass lenses. Or, each of the plurality of lenses is one of a plastic lens and a glass lens.

[0026] When the lens in the optical machine provided in the embodiment of the present application is a plastic lens or a glass lens, both can meet the use requirements. However, when the lens is a plastic lens, the cost of the lens can be reduced, which is conducive to reducing the cost of the optical machine.

[0027] A second aspect of the present application provides a display device, comprising a lens and an optical machine as described in any one of the first aspects.

[0028] A third aspect of the present application provides a vehicle, comprising a display device as described in the second aspect. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Figure 1 is a cross-sectional view of an optical machine in the related art. Figure 1 As shown, the optical machine includes a housing 110 and a lens 120. The housing 110 includes a receiving cavity. The lens 120 is disposed inside the receiving cavity and connected to the housing 110 by bonding at the bottom and bonding at the shoulder. The lens 120 is a rectangular plate-like structure. The bottom end surface of the lens 120 is bonded to the bottom wall of the receiving cavity by glue 130. The two opposite end walls of the lens 120 are respectively bonded to the two opposite side walls of the receiving cavity by glue 130, so that the lens 120 is connected to the housing 110.

[0051] However, since the reliability of the connection between the end wall of the lens 120 and the side wall of the accommodating cavity and the glue 130 and the housing 110 is low, the risk of the glue 130 peeling off is high. After a certain period of time or after the optical machine is vibrated, the connection between the glue 130 and the side wall of the accommodating cavity will fail, making the end wall of the lens 120 not infinite, and the lens 120 will shake, and even the connection between the lens 120 and the housing 110 will fail and fall off. Therefore, the reliability of the connection between the lens 120 and the housing 110 is low, which will reduce the position accuracy of the lens 120, and further reduce the optical quality.

[0052] In view of this, the embodiments of the present application provide an optical machine 200, a display device 100 and a vehicle, which can improve the reliability of the connection between the lens 20 and the housing 10, thereby improving the position accuracy of the lens 20 and further ensuring the optical quality.

[0053] Figure 2 This is a schematic diagram of the structure of a display device provided in an embodiment of the present application. Figure 2 As shown, the display device 100 of the embodiment of the present application includes a lens 300 and an optical engine 200. The lens 300 is arranged on the light-emitting side of the optical engine 200. The optical engine 200 is used to inject a light beam containing information to be displayed into the lens 300.

[0054] The display device 100 provided in the embodiment of the present application may include but is not limited to electronic devices such as a display, a projector, a television, a head-up display, etc. In the embodiment of the present application, the head-up display is used as the display device 100 for illustration.

[0055] The display device 100 provided in the embodiment of the present application may also be applied to transportation tools, which may include but are not limited to automobiles, ships, airplanes, or trains, etc. In the embodiment of the present application, the display device 100 is applied to an automobile for illustration.

[0056] The implementation method of the optical engine 200 provided in the embodiment of the present application is described below in conjunction with the accompanying drawings.

[0057] Figure 3 A schematic diagram of the internal structure of an optical machine provided in an embodiment of the present application, Figure 4 The optical engine 200 of the embodiment of the present application includes a housing 10, at least one lens 20 and at least one adhesive member 30, for example Figure 3 As shown, the optical machine 200 includes six lenses 20. Of course, the number of lenses 20 may be more or less than six. Exemplarily, the number of adhesive members 30 may be eighteen. Of course, the number of adhesive members 30 may be more or less than eighteen. The housing 10 includes at least one fixing group 11, such as Figure 3As shown, the housing 10 includes six fixing groups 11. Of course, the number of fixing groups 11 may be more or less than six. Figure 3 and Figure 4 It can be seen that each fixing group 11 corresponds to a lens 20, and each fixing group 11 includes two fixing platforms 12 arranged on opposite sides of the corresponding lens 20. The two fixing platforms 12 of each fixing group 11 are respectively bonded to opposite ends of the corresponding lens 20 through two adhesive members 30. At least one fixing platform 12 includes a clamping space 40 for accommodating a portion of the corresponding adhesive member 30, and the clamping space 40 is used to clamp the fixing platform 12 with the corresponding adhesive member 30. There is no limitation on the number of fixing platforms 12 having the clamping space 40, for example Figure 3 As shown, eleven of the twelve fixing tables 12 include the clamping spaces 40 . Of course, the number of the fixing tables 12 including the clamping spaces 40 may be more or less than twelve.

[0058] In the embodiment of the present application, the thickness direction of each lens 20 is defined as the first direction. Figure 5 X direction), the second direction (e.g. Figure 4 Y direction) and the third direction (e.g. Figure 4 Z direction) are perpendicular to each other.

[0059] Continue to see Figure 3 and Figure 4 As shown, along the second direction, the two fixing platforms 12 of each fixing group 11 are respectively arranged on opposite sides of the corresponding lens 20. In other words, the lens 20 is arranged between the two corresponding fixing platforms 12 along the second direction. Since the two opposite ends of the lens 20 along the second direction are respectively bonded to the two corresponding fixing platforms 12 through the two adhesive members 30, not only can the two opposite ends of the lens 20 along the second direction be respectively connected to the two corresponding fixing platforms 12 so that the shoulder of the lens 20 is connected to the housing 10, but also the lens 20 can be limited in the second direction so as to prevent the lens 20 from moving along the second direction, so as to ensure the position accuracy of the lens 20 in the second direction.

[0060] Continue to see Figure 4As shown, since part of the adhesive 30 is arranged inside the clamping space 40, the bonding area between the adhesive 30 and the fixing table 12 can be increased, so that the bonding performance between the adhesive 30 and the fixing table 12 can be improved, and then the reliability of the connection between the adhesive 30 and the fixing table 12 can be improved. In addition, when the glue peels off, for example, when the bonding force between the adhesive 30 and the fixing table 12 disappears, since the fixing table 12 is clamped with the adhesive 30, the connection between the adhesive 30 and the fixing table 12 will not fail, and the reliability of the connection between the adhesive 30 and the fixing table 12 can be improved. Therefore, by cooperating with the clamping space 40 and the adhesive 30, the reliability of the connection between the adhesive 30 and the fixing table 12 can be improved, not only the position accuracy of the lens 20 can be guaranteed to ensure the optical quality, but also the lens 20 can be prevented from being offset or falling off due to vibration to ensure the optical quality. In addition, since no new parts are introduced and too much space is not occupied, it can be applied to small space scenes, which is conducive to the miniaturization of the optical machine 200.

[0061] In the embodiment of the present application, there is no limitation on the specific shape of the lens 20. For example, the lens 20 may include but is not limited to a rectangular lens, a circular lens, etc. In addition, when there are multiple lenses 20, the shapes of the multiple lenses 20 may be the same or different. In other words, the lens 200 may include at least one type of lens 20. When there are multiple fixed groups 11, the shapes of the multiple lenses 20 corresponding to the multiple fixed groups 11 may also be the same or different, or some of the lenses 20 may have the same shape. For example, Figure 3 As shown, the multiple lenses 20 corresponding to the multiple fixed groups 11 can all be rectangular lenses.

[0062] In the embodiment of the present application, there is no limitation on the specific structure of the adhesive member 30. In addition, the adhesive member 30 may include but is not limited to glue, adhesive, etc. In the embodiment of the present application, glue is used as the adhesive member 30 as an example for description.

[0063] It should be noted that the number of the fixing groups 11 having the snap-in spaces 40 may be one or more, for example Figure 3 As shown, each fixing group 11 includes a snap-in space 40. In addition, since each fixing group 11 includes two fixing platforms 12 and one snap-in space 40 corresponds to one fixing platform 12, the number of snap-in spaces 40 in the fixing group 11 having the snap-in space 40 may be one or two. In addition, the number of snap-in spaces 40 of the plurality of fixing groups 11 may be the same, or the number of snap-in spaces 40 of the plurality of fixing groups 11 may be partially the same.

[0064] It should also be noted that when the optical machine 200 includes a plurality of lenses 20, each of the plurality of lenses 20 may correspond to a fixing group 11 and be connected to the housing 10 through the corresponding fixing group 11, for example Figure 3 Of course, in some embodiments, part of the multiple lenses 20 may be connected to the housing 10 through the fixing group 11. Therefore, the number of lenses 20 may be equal to the number of fixing groups 11, or the number of lenses 20 may be greater than the number of fixing groups 11.

[0065] Figure 5 for Figure 3 In some possible implementations, at least one engaging space 40 is used to engage the fixing platform 12 with the corresponding adhesive member 30 in the first direction. Figures 3 to 5 It can be known that each engaging space 40 is used to engage the fixing platform 12 with the corresponding adhesive component 30 in the first direction.

[0066] Accordingly, combined Figure 3 and Figure 4 It can be seen that along the second direction, a fixing platform 12 is respectively provided on the opposite sides of the lens 20, and the lens 20 is respectively bonded to the two fixing platforms 12 through two adhesives 30, which can prevent the lens 20 from shaking or falling off in the second direction due to vibration, so as to ensure the position accuracy of the lens 20 in the second direction. On this basis, the fixing platform 12 is clamped with the corresponding adhesive 30 in the first direction through the clamping space 40, which can prevent the lens 20 from shaking or falling off in the first direction due to vibration, and can ensure the position accuracy of the lens 20 in the first direction. Therefore, through the limitation of the lens 20 by the two fixing platforms 12 and the clamping of the clamping space 40 and the adhesive 30, the lens 20 can be limited in the first direction and the second direction, so as to improve the reliability of the connection between the lens 20 and the housing 10, and further improve the position accuracy of the lens 20.

[0067] It should be noted that, when there are multiple snap-in spaces 40, in addition to snapping the fixing table 12 and the adhesive 30 in the first direction, in some embodiments, each snap-in space 40 of a part of the multiple snap-in spaces 40 can also snap the fixing table 12 and the adhesive 30 in the first direction, and each snap-in space 40 of another part can also snap the fixing table 12 and the adhesive 30 in a fourth direction perpendicular to the third direction. The fourth direction may include but is not limited to the first direction and the second direction.

[0068] Figure 6 for Figure 3In some possible implementations, at least one snap-in space 40 is a snap-in groove, for example Figure 3 and Figure 6 As shown, each of the eleven card-joining spaces 40 is a card-joining slot. Of course, the number of card-joining slots can be more or less than eleven. Figure 5 and Figure 6 It can be seen that each snap-in slot includes a first slot 41 and a second slot 42 . The first slot 41 passes through the side wall of the fixing platform 12 and faces the lens 20 along the second direction. The second slot 42 passes through the top surface of the fixing platform 12 along the third direction.

[0069] It is understandable that if Figure 6 As shown, the clamping groove can also be understood as a notch provided at the top of the fixing platform 12 , and the inner wall of the notch encloses a clamping space 40 .

[0070] Combination Figure 4 It can be seen that by accommodating the portion of the adhesive 30 in the snap-fit ​​groove, not only can the adhesive 30 be snap-fitted with the fixing platform 12, but also the difficulty of setting the snap-fit ​​space 40 on the fixing platform 12 can be reduced. In addition, the snap-fit ​​groove does not affect the adjustment range of the lens 20, and can open up the coupling space of the lens 20. In addition, the snap-fit ​​groove occupies a small space, and the use position is flexible, which is conducive to the small volume design of the product.

[0071] In the embodiment of the present application, the specific structure of the clamping groove is not limited here. The clamping groove may include but is not limited to a U-shaped groove, an arc groove, a semicircular groove, a V-shaped groove, etc. Through these types of clamping grooves, the bonding performance of the adhesive 30 and the fixing platform 12 can be improved to improve the reliability of the connection between the adhesive 30 and the fixing platform 12. In addition, the fixing platform 12 can also be clamped with the corresponding adhesive 30 to improve the reliability of the connection between the adhesive 30 and the fixing platform 12.

[0072] For example, Figure 5 and Figure 6 As shown, the clamping groove may be a U-shaped groove, and the U-shaped groove may include a first groove wall 43, a second groove wall 44, a third groove wall 45, and a groove bottom 46. The first groove wall 43, the second groove wall 44, and the third groove wall 45 are arranged on the same side of the groove bottom 46 and are sequentially connected. There is an angle between the first groove wall 43 and the second groove wall 44, and there is an angle between the third groove wall 45 and the second groove wall 44. The groove bottom 46 is parallel to the top surface of the fixing platform 12. At least one of the first groove wall 43, the second groove wall 44, and the third groove wall 45 is perpendicular to the groove bottom 46. However, in some embodiments, at least one of the first groove wall 43, the second groove wall 44, and the third groove wall 45 may not be perpendicular to the groove bottom 46.

[0073] It should be noted that, when there are multiple clamping slots, the structures of the multiple clamping slots may be the same or different, or the structures of the multiple clamping slots may be partially the same.

[0074] It should also be noted that, in addition to being a snap-in groove, the snap-in space 40 may also be other structures that can accommodate part of the adhesive 30. For example, in some embodiments, the snap-in space 40 may also be a snap-in hole (not shown in the figure), and the snap-in hole includes an opening that passes through the top surface of the fixing platform 12 along the third direction. The snap-in hole may include but is not limited to a circular hole, a U-shaped hole or a rectangular hole.

[0075] Therefore, when there are multiple card-joining spaces 40, each of the multiple card-joining spaces 40 can be one of a card-joining hole and a card-joining groove, or a part of the multiple card-joining spaces 40 can also be a card-joining groove and another part can also be a card-joining hole.

[0076] In some possible implementations, at least one fixing platform 12 includes a body portion 13, such as Figure 3 As shown, the twelve fixing platforms 12 all include a main body 13. Of course, the number of fixing platforms 12 having a main body 13 may be more or less than twelve. Figure 5 and Figure 6 It can be seen that, along the second direction, there is a matching gap 50 between the main body 13 and the end surface of the corresponding lens 20 for accommodating part of the adhesive 30. The main body 13 of at least one fixing platform 12 includes a clamping space 40, such as Figure 3 As shown, eleven of the twelve main body portions 13 include the snap-fitting spaces 40 . Of course, the number of the main body portions 13 including the snap-fitting spaces 40 may be more or less than eleven.

[0077] Accordingly, see Figure 5 and Figure 6 As shown, by providing a matching gap 50 for accommodating the adhesive 30 between the main body 13 and the lens 20, the adhesive 30 can be bonded to the lens 20 and the fixing platform 12 respectively. In addition, the two fixing platforms 12 can also limit the corresponding lens 20 from shaking along the second direction, thereby ensuring the position accuracy of the lens 20.

[0078] In the embodiment of the present application, there is no limitation on the specific structure of the main body 13. For example, the main body 13 may be a columnar structure extending along the third direction.

[0079] In the embodiment of the present application, each of the plurality of matching gaps 50 is used to accommodate a portion of the adhesive 30. However, in some embodiments, at least one of the plurality of matching gaps 50 may also be used to accommodate the adhesive 30. In other words, a portion of the plurality of matching gaps 50 is used to accommodate a portion of the adhesive 30, and another portion is used to accommodate the adhesive 30.

[0080] When there are multiple matching gaps 50, the structures of the multiple matching gaps 50 may be the same, or the structures of the multiple matching gaps 50 may be different, or the multiple matching gaps 50 may have a part of the same structure and a part of the different structure. In addition, along the third direction, the length of the portion of each of the multiple adhesives 30 extending into the corresponding matching gap 50 may be the same, or the length of the portion of each of the multiple adhesives 30 extending into the corresponding matching gap 50 may be different, or the length of the portion of at least two of the multiple adhesives 30 extending into the corresponding matching gap 50 may be the same.

[0081] In the embodiment of the present application, the specific structure of the fitting gap 50 is not limited here.

[0082] In some possible implementations, at least one matching gap 50 includes a first gap section 51 and a second gap section 52, for example Figure 3 As shown, each of the twelve matching gaps 50 includes a first gap section 51 and a second gap section 52. Of course, in some embodiments, the number of matching gaps 50 formed by the first gap section 51 and the second gap section 52 may be more or less than twelve. Figures 4 to 6 As shown, along the second direction, the width of the first gap section 51 is greater than the width of the second gap section 52. Along the third direction, the first gap section 51 is close to the top of the fixing platform 12 and close to the clamping space 40, and the second gap section 52 is close to the bottom of the fixing platform 12.

[0083] Accordingly, the fitting gap 50 is formed by the first gap section 51 and the second gap section 52, which can increase the bonding area between the fixing platform 12 and the adhesive 30, thereby improving the bonding performance between the adhesive 30 and the fixing platform 12, and further improving the reliability of the connection between the adhesive 30 and the fixing platform 12. In addition, the difficulty of setting the adhesive 30 inside the fitting gap 50 can be reduced, and the speed of the adhesive 30 bonding the fixing platform 12 and the lens 20 can be increased. For example, when the adhesive 30 is glue, the difficulty of the glue feeding device aligning with the fitting gap 50 can be reduced, so that the glue can enter the inside of the fitting gap 50 more easily. In addition, the deformation capacity of the adhesive 30 can be improved, which helps to increase the force range of the adhesive 30.

[0084] It is understandable that if Figure 6 As shown, since the width of the first gap segment 51 in the second direction is greater than the width of the second gap segment 52 in the second direction, the first gap segment 51 can be understood as an avoidance gap set at the top of the fixing table 12, which can not only increase the bonding area between the fixing table 12 and the adhesive 30, but also reduce the difficulty of the adhesive 30 entering the fitting gap 50.

[0085] Continue to see Figure 5 and Figure 6 As shown, since the engaging space 40 is an engaging groove, the engaging space 40 is connected to the interior of the first gap section 51. However, in some embodiments, when the engaging space 40 is an engaging hole, the engaging hole is not connected to the interior of the first gap section 51.

[0086] It should be noted that when the adhesive 30 is bonded to the lens 20 and the fixing platform 12 respectively, the first gap section 51 may be provided with a portion of the adhesive 30 and the second gap section 52 may not be provided with the adhesive 30 (not shown in the figure), or Figure 4 As shown, a portion of the adhesive 30 may also be disposed inside the first gap section 51 and a portion of the adhesive 30 may also be disposed inside the second gap section 52 .

[0087] In some possible implementations, along the third direction (eg Figure 4 In the Z direction), the depth of at least one engaging space 40 is equal to the height of the first gap section 51, for example Figure 3 As shown, the depth of each of the eleven engaging spaces 40 is equal to the height of the first gap section 51 . Of course, the number of engaging spaces 40 whose depth is equal to the height of the first gap section 51 may be more or less than eleven.

[0088] Accordingly, by making the depth of the clamping space 40 equal to the height of the first gap section 51, the volume of the clamping space 40 can be increased, thereby increasing the volume of the portion of the adhesive 30 extending into the clamping space 40, and further increasing the bonding area between the adhesive 30 and the inner wall of the clamping space 40, so as to further improve the bonding performance of the adhesive 30 and the fixing platform 10, so that the connection between the adhesive 30 and the fixing platform 10 is not easy to fail. Therefore, by making the depth of the clamping space 40 equal to the height of the first gap section 51, the bonding performance of the adhesive 30 and the fixing platform 10 can be further improved, so as to improve the reliability of the adhesive 30 and the fixing platform 10. In addition, the reliability of the clamping of the adhesive 30 and the fixing platform 12 can also be improved.

[0089] It should be noted that, along the third direction, in addition to the depth of each of the multiple engaging spaces 40 being equal to the height of the first gap section 51, in some embodiments, the depth of each of the multiple engaging spaces 40 may also be less than the height of the first gap section 51 (not shown in the figure). Alternatively, in some embodiments, the depth of a portion of the multiple engaging spaces 40 may also be equal to the height of the first gap section 51, and the depth of another portion of the engaging spaces 40 may also be less than the height of the first gap section 51 (not shown in the figure). Alternatively, in some embodiments, the depth of at least one engaging space 40 may also be greater than the depth of the first gap section 51 (not shown in the figure).

[0090] In some possible implementations, at least one fixing platform 12 may further include at least one extension portion 14, for example Figure 3 As shown, each of the twelve fixing platforms 12 includes an extension portion 14. Of course, the number of fixing platforms 12 having the extension portion 14 may be less than or more than twelve. Along the first direction, at least one of the two opposite sides of at least one lens 20 is provided with an extension portion 14, for example Figure 3 As shown, at least one of the two opposite sides of each of the six lenses 20 is provided with an extension portion 14. Such a configuration can not only increase the bonding area between the fixing platform 12 and the adhesive member 30, thereby improving the reliability of the connection between the adhesive member 30 and the fixing platform 12, but also limit the lens 20 in the second direction without affecting the light transmitted by the lens 20, thereby preventing the lens 20 from shaking in the second direction, thereby ensuring the position accuracy of the lens 20.

[0091] Continue to see Figure 5 As shown, along the first direction, there is a limiting gap 60 between each extension portion 14 and the corresponding lens 20, and the limiting gap 60 is used to accommodate a portion of the adhesive 30, so that the extension portion 14 and the lens 20 can be bonded, which can not only increase the bonding area between the adhesive 30 and the fixing platform 12, thereby improving the reliability of the connection between the adhesive 30 and the fixing platform 12, but also the adhesive 30 can be used to limit the lens 20 in the first direction.

[0092] Continue to see Figure 5 and Figure 6 As shown, since each fixing platform 12 includes a main body 13, the main body 13 and the extension 14 can be an integrated structure, which can reduce the manufacturing difficulty of the fixing platform 12 and improve the production efficiency of the fixing platform 12. Of course, in some embodiments, the main body 13 and the extension 14 can also be a split structure.

[0093] In the embodiment of the present application, there is no limitation on the specific structure of the extension portion 14. For example, the extension portion 14 may be a columnar structure extending along the third direction.

[0094] It should be noted that, when there are multiple lenses 20, in addition to at least one of the two opposite sides of each lens 20 in the multiple lenses 20 being provided with an extension portion 14, at least one of the two opposite sides of some of the lenses 20 in the multiple lenses 20 may also be provided with an extension portion 14 (not shown in the figure).

[0095] It should also be noted that when there are multiple fixed platforms 12, Figure 3 As shown, each fixing stage 12 includes an extension portion 14. However, in some embodiments, when there are multiple fixing stages 12, some of the multiple fixing stages 12 may include an extension portion 14. In addition, when there are multiple fixing stages 12 with extension portions 14, the number of extension portions 14 of the multiple fixing stages 12 may be at least partially the same, in other words, the number of extension portions 14 of at least one fixing stage 12 may be the same.

[0096] In some possible implementations, at least one lens 20 is provided with extensions 14 on two opposite sides thereof, for example Figure 3 As shown, five of the six lenses 20 are provided with extensions 14 on both sides thereof. Of course, the number of lenses 20 provided with extensions 14 on both sides thereof may be more or less than five. The number of extensions 14 on both sides thereof of at least one lens 20 may be the same or different, for example Figure 3 As shown, the number of the extension parts 14 on the opposite sides of a part of the plurality of lenses 20 is the same, and the number of the extension parts 14 on the opposite sides of another part is different. By providing the same or different number of extension parts 14 on the opposite sides of at least one lens 20, the bonding area between the fixing platform 12 and the adhesive 30 can be increased without affecting the optical path, thereby achieving the purpose of improving the position accuracy of the lens 20.

[0097] There is no limitation on the number of the extensions 14 on the opposite sides of the lens 20. Figure 3 As shown, one or two extensions 14 are respectively disposed on opposite sides of the partial lens 20. In other words, each of the two fixing platforms 12 corresponding to the partial lens 20 includes one or two extensions 14. Figure 3 As shown, some of the lenses 20 among the multiple lenses 20 are provided with two extension portions 14 on one side and one extension portion 14 on the other side. In other words, one of the two fixing platforms 12 corresponding to the lenses 20 includes one extension portion 14 and the other fixing platform 12 includes two extension portions 14.

[0098] Of course, in addition to providing the extension portion 14 on both opposite sides of the lens 20, the extension portion 14 may also be provided on one side of the lens 20 (for example, Figure 3In addition, in some embodiments, when there are multiple lenses 20, the extending portions 14 may be disposed on opposite sides of one portion of the multiple lenses 20, and the extending portion 14 may be disposed on one side of another portion, for example Figure 3 As shown, five of the six lenses 20 are provided with extension portions 14 on two opposite sides, and the remaining one is provided with an extension portion 14 on one side.

[0099] In some possible implementations, at least one lens 20 is disposed inside the housing 10, for example Figure 3 As shown, all lenses 20 of the optical machine 200 are arranged inside the housing 10. Along the third direction, one end of each lens 20 of at least one lens 20 is bonded to the inner wall of the housing 10, and the other end is bonded to the corresponding two fixing platforms 12, for example Figure 4 As shown, one end of each lens 20 is bonded to the inner wall of the housing 10 through an adhesive 30, and the other end is bonded to the corresponding two fixing platforms 12. This arrangement can protect the lens 20 and prevent accidental damage to the lens 20. In addition, one end of the lens 20 is bonded to the inner wall of the housing 10, and the other end is bonded to the corresponding two fixing platforms 12, so that the lens 20 is connected to the housing 10 through the scheme of main bonding at the bottom and auxiliary fixing at the shoulder, which can prevent the lens 20 from vibrating or falling off due to vibration.

[0100] In the embodiment of the present application, the specific structure of the housing 10 is not limited here. Figure 4 As shown, the housing 10 may include a cover member 15 and an outer shell member 16 . The outer shell member 16 includes at least one fixing group 11 . The cover member 15 covers the notch of the receiving groove and forms an receiving cavity with the outer shell member 16 for receiving at least one lens 20 .

[0101] In some possible implementations, the housing 10 may be a plastic housing 10, and the at least one fixing platform 12 may be a plastic fixing platform 12. By using the plastic housing 10 in conjunction with the lens 20, the cost of the housing 10 may be reduced, thereby reducing the cost of the optical machine 200.

[0102] In some possible implementations, the optical machine 200 includes a plurality of lenses 20, each of which is a plastic lens 20 and a glass lens 20. For example, as shown in the figure, each of which is a glass lens 20. Of course, in some embodiments, each of which may be a plastic lens 20. Alternatively, in some embodiments, a portion of the plurality of lenses 20 may be a plastic lens 20, and another portion may be a glass lens 20.

[0103] Accordingly, when the lens 20 is a plastic lens 20 or a glass lens 20, both can meet the use requirements. However, when the lens 20 is a plastic lens 20, the cost of the lens 20 can be reduced, which is conducive to reducing the cost of the optical machine 200.
