[0032] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0033] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0035] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0036] like Figure 1 As shown, a specific implementation of the lens assembly provided in this embodiment includes: an adjustment bracket, a lens 2 and a sensor board 3, wherein the adjustment bracket has an adjustment board 1 capable of adjusting the inclination; the lens 2 is mounted on the adjustment board 1 through a first fastener 5; the sensor board 3 is arranged between the lens 2 and the adjustment board 1, and the sensor board 3 has a through hole 4, through which the first fastener 5 can pass, the inner wall of the through hole 4 is a light hole, and the inner diameter of the through hole 4 is greater than or equal to the outer diameter of the first fastener 5. In this arrangement, when the lens 2 is connected to the adjustment board 1 through the first fastener 5, the first fastener 5 only passes through the through hole 4 of the sensor board 3, and during use, the sensor board 3 will not bear the force of the first fastener 5, thereby protecting the sensor board 3 from damage.
[0037] like Figure 1 As shown, in the lens assembly provided in this embodiment, the number of the first fasteners 5 and the number of the through holes 4 is two, which correspond to each other, and the two first fasteners 5 are symmetrically arranged around the lens 2. Of course, the above description is not restrictive, and in some alternative implementations, the number of the first fasteners 5 and the number of the through holes 4 may also be other numbers.
[0038] like Figure 2As shown, in the lens assembly provided in this embodiment, the adjustment bracket includes: a first fixed bracket 6 and a second fixed bracket 7, the first end of the adjustment plate 1 is rotatably connected to the first fixed bracket 6 through a first rotating shaft 8, and the second end of the adjustment plate 1 is rotatably connected to the second fixed bracket 7 through a second rotating shaft 9. In this way, when the tilt angle is adjusted, the rotation of the adjustment plate 1 can be made more stable. Of course, the above description is not restrictive, and in some alternative embodiments, one of the first fixed bracket 6 and the second fixed bracket 7 can be omitted.
[0039] like Figure 3 As shown, in this embodiment, the first end of the adjustment plate 1 has a first extension arm 10 extending toward a side away from the lens 2, and the first rotation shaft 8 is arranged on the first extension arm 10; the second end of the adjustment plate 1 has a second extension arm 11 extending toward a side away from the lens 2, and the second rotation shaft 9 is arranged on the second extension arm 11. Such an arrangement can improve the flexibility of adjusting the inclination angle of the adjustment plate 1, so that the adjustment plate 1 can adjust the inclination angle in a wider range. Of course, the above description is not restrictive. In some alternative embodiments, the first rotation shaft 8 and the second rotation shaft 9 can also be directly connected to the end surface of the adjustment plate 1.
[0040] like Figure 4 , Figure 5 As shown, in this embodiment, the first extension arm 10 is provided with a limit plate 12 protruding outward along the end of the adjustment plate 1, and the first fixed bracket 6 has limit columns 13 on both sides of the first rotating shaft 8 for cooperating with the limit plate 12. When adjusting the inclination angle of the adjustment plate 1, the two limit columns 13 cooperate with the limit plate 12 to limit the adjustment range of the inclination angle of the adjustment plate 1. Of course, the above description is not restrictive, and in some alternative embodiments, the limit columns 13 and the limit plates 12 can be omitted.
[0041] like Figure 4 As shown, in this embodiment, there are two limit plates 12, which are respectively arranged on both sides of the first rotating shaft 8. Through the one-to-one cooperation between the two limit plates 12 and the two limit posts 13, the limiting range of the inclination adjustment of the limit plate 12 can be improved. Of course, the above description is not restrictive. In some alternative embodiments, there can be only one limit plate 12, for example, it can be made into a wider block.
[0042] like Figure 4 , Figure 5As shown, in this embodiment, the free end of the second extension arm 11 is provided with an arc tooth structure 14, the second fixed bracket 7 is connected to a motor 15, the output shaft of the motor 15 is connected to a gear 16, and the gear 16 is meshed with the arc tooth structure 14 of the second extension arm 11. With such a configuration, the inclination of the adjustment plate 1 can be adjusted by forward or reverse rotation of the motor 15, thereby achieving automation. Of course, the above description is not restrictive. In some alternative embodiments, the output shaft of the motor 15 can also be connected to the adjustment plate 1 using other transmission structures, such as belt drive, chain drive, etc. In addition, in some places where electric adjustment is not required, the motor 15 can be omitted.
[0043] like Figure 1 As shown, in this embodiment, the sensor board 3 has a positioning hole 17, and the lens 2 has a positioning pin 18 for inserting into the positioning hole 17. During assembly, the positioning pin 18 on the lens 2 is first inserted into the positioning hole 17 on the sensor board 3 for pre-positioning, and then the lens 2 is fastened and mounted on the adjustment bracket using the first fastener 5. Of course, the above description is not restrictive, and in some alternative embodiments, the positioning hole 17 and the positioning pin 18 can be omitted.
[0044] like Figure 1 , Figure 2 As shown, in this embodiment, the sensor board 3 is connected to the adjustment board 1 through the second fastener 19. Such a configuration can improve the stability of the sensor board 3. Of course, the above description is not restrictive. In some alternative embodiments, the second fastener 19 can be omitted, and the sensor board 3 can be stabilized only by the pressing force between the lens 2 and the adjustment board 1.
[0045] like Figure 6 As shown, in this embodiment, the lens 2 is detachably mounted on the lens base 20, and the lens base 20 is connected to the adjustment plate 1 through the first fastener 5. The positioning pin 18 is mounted on the lens base 20. This arrangement can facilitate the replacement of different lenses 2. Of course, the above description is not restrictive, and in some alternative embodiments, the lens 2 can also be an integrated structure.
[0046] like Figure 6 As shown, in this embodiment, the lens 2 is detachably connected to the lens base 20 through a threaded structure. With this arrangement, the lens 2 can be installed more conveniently and stably. Of course, the above description is not restrictive. In some alternative embodiments, the lens 2 can also be connected to the lens base 20 using other structures, for example, by plugging and snapping.
[0047] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
