Description

Technical field

[0001] The invention relates to a camera, in particular to a quick-install camera module with a heating function and a camera module lens barrel. [Background Technology]

[0002] When shooting in rainy and foggy weather, the lens is easily covered with a layer of fog, which affects the shooting effect. To solve this problem, a heater is currently added to the lens part. The existing lens with a heater structure achieves electric heating by adding a wire to the lens mouth and connecting it to the PCB board. The wire is arranged between the lens barrel and the sleeve, and the accommodation space between the two is only used to place the wire. The remaining accommodation space is not well utilized. For the lens as a whole, this structure requires a large product space layout, which is not conducive to the miniaturization of the camera. [Summary of the invention]

[0003] The object of the present invention is to provide a quick-install camera module with a heating function and a camera module lens barrel thereof, which can reduce the space requirement of the electric heating element for the camera module, thereby realizing miniaturization of the camera.

[0004] This application is achieved through the following technical solutions:

[0005] The camera module lens barrel comprises a receiving portion for accommodating the conductive portion of the electric heating element. The receiving portion is arranged on the peripheral side of the lens barrel and extends backward along the front end of the lens barrel axis.

[0006] As described above, the camera module lens barrel, the accommodating portion includes a limiting groove for cooperating with the conductive portion of the electric heating element to achieve limiting and a wire groove for placing the conductive portion of the electric heating element.

[0007] As described above, the camera module lens barrel has a front end provided with a locking groove that communicates with the limiting groove.

[0008] As described above, the camera module lens barrel has a front end provided with a placement platform for placing the main body of the electric heating element, and an opening communicating with the positioning groove is provided on the edge of the placement platform, and the opening is used to allow the conductive part of the electric heating element to pass through and bend to the peripheral side of the lens barrel.

[0009] A quick-install camera module with a heating function comprises a first lens, an electric heating element, a sleeve, a pressure ring and the camera module lens barrel as described above.

[0010] As described above, the quick-release camera module with heating function, the electric heating element includes a main body placed on the placement table, a wire body extending from the front end to the rear and hidden in the wire groove, a connector connecting the main body and the wire body, and an electrode plate exposed on the outside of the rear end of the lens barrel.

[0011] As described above, in the quick-release camera module with heating function, the connecting member passes through the opening and is bent and fitted to the outside of the lens barrel. The connecting member includes a bent portion that fits the positioning groove and an extension portion extending backward along the bent portion. The extension portion is embedded in the limiting groove on the outside of the lens barrel.

[0012] As described above, in the quick-release camera module with heating function, the sleeve is sleeved on the outside of the lens barrel to cover the connector and the wire body, and a first sealing layer is provided at the connection between the sleeve and the lens barrel.

[0013] As described above, in the quick-release camera module with heating function, the pressure ring is sleeved on the rear end of the lens barrel and a second sealing layer is provided at the connection between the two. The pressure ring is provided with a receiving groove that cooperates with the electrode plate, and the receiving groove and the electrode plate are insulated.

[0014] As described above, in the quick-release camera module with a heating function, the first lens includes a lens and a lens limiting cover for fixing the lens to the front end of the electric heating element. A connecting portion is provided on the outer side of the front end of the lens barrel, and the lens limiting cover cooperates with the connecting portion to achieve connection with the lens barrel.

[0015] Compared with the prior art, this application has the following advantages:

[0016] 1. The camera module lens barrel of the present invention includes a receiving portion for accommodating the conductive portion of the electric heating element. The receiving portion is arranged on the circumference of the lens barrel and extends rearward along the front end of the lens barrel axis. The conductive wire of the existing lens heater is exposed outside the lens barrel, and space for the conductive wire needs to be reserved, which makes it impossible to miniaturize the camera. Compared with the structure of the existing lens heater, by hiding the conductive portion of the electric heating element in the receiving portion, it can reduce the product space requirement of the electric heating element for the camera module, thereby achieving miniaturization of the camera.

[0017] 2. The accommodating portion includes a limiting groove for cooperating with the conductive part of the electric heating element to achieve limiting and a wire groove for placing the conductive part of the electric heating element, wherein the limiting groove is arranged at the front end of the wire groove and the two are connected. The wire groove can play a certain limiting role on the conductive part of the electric heating element, and the end of the electric heating element is in a relatively loose state. This structure can better limit the electric heating element.

[0018] 3. The sleeve is sleeved on the outside of the lens barrel to cover the connector and the wire body, wherein the inner side of the sleeve is close to the outside of the lens barrel. Compared with the wire body being arranged between the lens barrel and the sleeve, it can confine the wire body in the wire groove, thereby preventing the wire body from moving between the lens barrel and the sleeve and causing the wire body to be entangled, and the lens barrel and the sleeve from causing wear on the wire body; the lens barrel and the sleeve are in close contact, thereby preventing the camera module from shaking during use and affecting the stability of the camera module.

[0019] 4. The lens limit cover is threadedly connected to the lens barrel, the sleeve is threadedly connected to the lens barrel, and the pressure ring is threadedly connected to the lens barrel, which makes disassembly and assembly more convenient and the connection more stable.

[0020] 5. A first sealing layer is provided at the connection between the sleeve and the lens barrel, and a second sealing layer is provided at the connection between the pressure ring and the lens barrel, which can achieve a waterproof effect and prevent rainwater from entering the camera module when used in rainy and foggy weather, causing a short circuit in the electric heating element.
