Description

Technical Field

[0001] The utility model relates to the technical field of pan / tilt camera, in particular to a lens assembly structure. Background Art

[0002] In existing gimbal cameras, the lens board is usually assembled directly without auxiliary devices, resulting in inaccurate alignment between the lens board and the lens barrel. Due to limited internal space, the installation position of the lens board cannot be accurately controlled, which makes assembly difficult and time-consuming. In addition, the common heat dissipation method for the lens board is to use a thermally conductive silicone gasket to connect it to the metal shell, and to conduct the heat of the lens board through the metal shell. However, the heat dissipation effect is not good, and when the temperature of the metal shell is too high, the user experience is not good. In addition, the common anti-static method for existing lens boards is to use a metal spring to contact the metal shell to achieve a grounding effect and realize the anti-static function.

[0034] like Figure 1As shown, the present embodiment provides a lens assembly structure, including an adapter 100, a lens barrel 200 and a lens plate 300. Among them, the lens barrel 200 is provided with a first mounting port 210 and a second mounting port 220, and the first mounting port 210 is used to install the lens. The lens plate 300 is connected to the adapter 100. During assembly, the adapter 100 can be held by hand to pass the lens plate 300 and the adapter 100 through the second mounting port 220 and fixed in the lens barrel 200. The lens plate 300 is kept perpendicular to the axis of the lens barrel 200, and the axis is an axis extending along the length direction of the lens barrel 200. Through the setting of the adapter 100, the assembly process is more convenient and easy to operate, and the position of the lens plate 300 is also more accurate. Further, a copper-clad area 310 is provided on the lens plate 300 near the adapter 100, and the adapter 100 is connected to the copper-clad area 310. The adapter 100 is made of metal material. For example, the adapter 100 can be made of copper or aluminum. When the adapter 100 is made of metal material, the thermal conductivity between the adapter 100 and the lens board 300 is high, and the heat of the lens board 300 can be quickly transferred to the adapter 100 via the copper-clad area 310, and then the adapter 100 dissipates the heat to the end away from the lens board 300, thereby achieving a good heat dissipation effect on the lens board 300, and also preventing the temperature of the lens barrel 200 from being too high, affecting the user experience.

[0035] Optionally, the lens assembly structure further includes an antistatic component 400, a wiring port 320 is provided on the lens plate 300, the antistatic component 400 is sandwiched between the lens plate 300 and the adapter 100, at least a portion of the adapter 100 presses the antistatic component 400 against the wiring port 320, and the antistatic component 400 can completely cover the wiring port 320. By setting the antistatic component 400, the generation of static electricity at the wiring port 320 can be avoided, and the same effect as grounding is achieved. In this embodiment, the wiring port 320 or the lens barrel 200 does not need to be grounded, and the structure is simpler and more portable.

[0036] See also Figure 2 The adapter 100 in this embodiment is an integrated structure and can be formed by cutting and bending a metal sheet. Alternatively, it can be formed by mold injection molding. Specifically, the adapter 100 includes a main body plate 110, and a fixing ear 120 and a pressing plate 130 connected to the main body plate 110, the fixing ear 120 and the pressing plate 130 both extend to a side close to the lens board 300, wherein the fixing ear 120 is connected to the copper-clad area 310 of the lens board 300, and the pressing plate 130 presses the anti-static component 400 against the wiring port 320, and the anti-static component 400 is fixed by the pressing plate 130.

[0037] Furthermore, in this embodiment, two fixing ears 120 are provided, and the two fixing ears 120 are arranged on opposite sides of the main plate 110. By providing two fixing ears 120, the stability and reliability of the connection between the adapter 100 and the lens plate 300 can be improved, and the fixation is more secure. The pressing plate 130 is led out from the side of the main plate 110 adjacent to the fixing ears 120 and extends in the direction close to the lens plate 300, so that the anti-static component 400 can be pressed tightly at the wiring port 320 on the lens plate 300.

[0038] Exemplarily, in this embodiment, the adapter 100 and the lens board 300 are fixed by a detachable connection. Specifically, the adapter 100 further includes a screw (not shown in the figure), a through hole 121 is provided on the fixing ear 120, and a fixing hole 311 is provided at the copper-clad area 310 of the lens board 300. The screw passes through the through hole 121 and is threadedly connected to the fixing hole 311, thereby fixing the adapter 100 to the lens board 300 by the screw. Of course, in other embodiments, the adapter 100 and the lens board 300 can also be connected by welding. Although this connection method is more firmly fixed, it is more inconvenient to disassemble. Once the adapter 100 and the lens board 300 are welded, it is difficult to separate the two.

[0039] Continue to see Figure 2 The pressing plate 130 in this embodiment includes a connecting portion 131 and a crimping portion 132. One end of the connecting portion 131 is connected to one side of the main plate 110, and the connecting portion 131 is arranged on the adjacent side of the fixing ear 120. The other end of the connecting portion 131 extends in the direction of the lens plate 300 (the same as the extending direction of the fixing ear 120), and the connecting portion 131 is connected to the crimping portion 132. The crimping portion 132 is in the shape of a flat plate, and the cross section is U-shaped, and the crimping portion 132 is parallel to the lens plate 300. Through the above arrangement, the end face of the crimping portion 132 with a larger area contacts the antistatic component 400, which can improve the fixing effect of the antistatic component 400 on the lens plate 300. At the same time, the contact area between the crimping portion 132 and the antistatic component 400 is larger, and then the contact area between the antistatic component 400 and the wiring port 320 is larger, and the antistatic component 400 can completely cover the wiring port 320 and be in close contact with the wiring port 320. Compared with the conventional point-to-point conductive contact method, in this embodiment, the contact between the crimping portion 132 and the antistatic component 400 and between the antistatic component 400 and the wiring port 320 are both surface-to-surface contacts, which is beneficial to improving the antistatic effect.

[0040] As an optional solution, the lens assembly structure further includes a lens barrel cover (not shown in the figure), which is buckled at the second mounting port 220 of the lens barrel 200, the main plate 110 is flat and arranged in parallel with the lens plate 300 and the lens barrel cover, and a heat-conducting gel is arranged on the side of the main plate 110 away from the lens plate 300, and the heat-conducting gel is connected to the inner side of the lens barrel cover. The lens barrel cover can also be made of metal material, and the heat of the adapter 100 is further transferred to the lens barrel cover by the arrangement of the heat-conducting gel, and then the heat is dissipated to the external space by the lens barrel cover, so that the heat dissipation effect is better, and the temperature at the lens barrel 200 is not greatly affected, and the user experience is better.

[0041] Further, the main body plate 110 is provided with a snap-on convex portion 111, and the lens barrel cover is provided with a snap-on slot, and the snap-on convex portion 111 is snap-on with the snap-on slot, so that this installation method is more convenient and has a higher efficiency of assembly and disassembly. By way of example, in this embodiment, four snap-on convex portions 111 may be provided on the main body plate 110, and the four snap-on convex portions 111 are respectively arranged at the four corners of the main body plate 110, so that when the main body plate 110 and the lens barrel cover are assembled, the force is more uniform and the connection is more stable. Of course, in other embodiments, the main body plate 110 and the adapter 100 may also be connected in other ways, which are not limited here.

[0042] Continue to see Figure 1 and Figure 3 , the antistatic component 400 in this embodiment includes a first conductive layer 410, a foam layer 420 and a second conductive layer 430, the foam layer 420 is sandwiched between the first conductive layer 410 and the second conductive layer 430, the first conductive layer 410 abuts against the crimping portion 132 of the adapter 100, and the second conductive layer 430 abuts against the wiring port 320 of the lens board 300. Optionally, the first conductive layer 410 is polyester fiber cloth, the foam layer 420 is polyether sponge, and the second conductive layer 430 is conductive glue. The conductive glue can conduct the static charge generated by the wiring port 320 to the polyether sponge, and then the polyether sponge disperses the static charge, so that the foam layer 420 is not charged, effectively reducing the occurrence of static discharge at the wiring port 320, and avoiding sparks or damage to the wiring port 320 caused by static discharge. In addition, the polyether sponge also has good elasticity and toughness, can effectively reduce vibration and impact, avoid rigid collision between the adapter 100 and the wiring port 320, and protect the safety of the wiring port 320. The polyester fiber cloth can protect the foam layer 420 and reduce wear.

[0043] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
