Description

Technical Field

[0001] The utility model relates to the technical field of driving recorders, in particular to a lens-extending driving recorder. Background Art

[0002] A driving recorder (also known as an in-vehicle camera, a driving camera, a driving DV, etc.) is an electronic device installed in a vehicle for recording images and sounds during vehicle driving. The shapes and inclination angles of the front windshield glass of different vehicle models are different. Even in the same vehicle model, there may be slight differences in the front windshield glass of different vehicles. These differences will affect the field of view and focal length of the driving recorder. Therefore, due to the different installation positions of the driving recorder, focus adjustment is required.

[0003] Existing driving recorders allow users to manually adjust the lens to change the focal length. It is necessary to disassemble the recorder housing of the driving recorder and then manually rotate the lens assembly to finely adjust the focal length. Some high-end driving recorders are equipped with an autofocus function. The former is more troublesome as it requires disassembling the recorder housing, and the latter has a complex lens structure and a high manufacturing cost. Therefore, we propose a lens-extending driving recorder to solve this problem. Summary of the Invention

Detailed implementation manner

[0023] In order to more clearly and completely illustrate the technical solution of the present utility model, the present utility model will be further described below with reference to the accompanying drawings.

[0024] Please refer to Figures 1 - 5 , a lens-extending driving recorder proposed by the present utility model includes a recorder housing 1 and a lens housing 2. The recorder housing 1 and the lens housing 2 are fixedly connected to each other. An installation hole 4 is provided on one side of the recorder housing 1. The lens housing 2 includes a mounting plate 3. The mounting plate 3 is fixedly installed in the installation hole 4 by bolts. A turning handle 5 is rotatably installed on one side of the mounting plate 3. A lens mounting cylinder 6 is slidably installed in the turning handle 5. The lens body is fixedly installed in the lens mounting cylinder 6. Threaded protrusions 7 are provided on the inner wall of the turning handle 5. Threaded grooves 8 are provided on the outer side of the lens mounting cylinder 6. The turning handle 5 and the lens mounting cylinder 6 are threadedly connected through the cooperation of the threaded protrusions 7 and the threaded grooves 8, so as to drive the lens mounting cylinder 6 and the lens to linearly move synchronously and adjust the focal length. A rotating connecting member is provided on one side of the mounting plate 3. The turning handle 5 is sleeved on the outer side of the rotating connecting member. A plurality of anti-slip grooves are provided on the outer side of the turning handle 5, which is convenient for the user to rotate the turning handle 5.

[0025] As Figure 2 shown, two guiding rods 14 are fixedly installed on one side of the mounting plate 3. Two guiding cylinders 13 are provided on the inner wall of the cylinder two 10. The guiding cylinders 13 are slidably sleeved on the outer sides of the corresponding guiding rods 14.

[0026] During actual use, the user rotates the rotating handle 5, thereby driving the thread protrusion 7 to rotate along the thread groove 8. Under the limitation of the guide rod 14 and the guide cylinder 13, the lens mounting cylinder 6 moves linearly upward, thereby driving the lens to move away from the side of the recorder housing 1. Moreover, the smaller the pitch of the thread protrusion 7, the higher the displacement accuracy.

[0027] As Figure 3 and Figure 4 shown, the lens mounting cylinder 6 includes a first cylinder 9 and a second cylinder 10. The first cylinder and the second cylinder 10 are fixedly connected by a tapered shell 11. The radius of the tapered shell 11 is greater than that of the first cylinder 9. A sealing shell 12 and a lens cap 20 are slidably sleeved on the outer side of the lens mounting cylinder 6. The lens cap 20 is fixedly clamped to the first cylinder 9 through a snap structure. The sealing shell 12 is movably and sealingly clamped between the tapered shell 11 and the lens cap 20.

[0028] As Figure 3 and Figure 5 shown, two connecting grooves 15 are formed on the outer side of the lens mounting cylinder 6. Both the inner and outer sides of the connecting grooves 15 are open. A ring edge 16 is arranged on the inner wall of the lens cap 20. Two partition plates 17 are fixedly installed between the ring edge 16 and one side inner wall of the lens cap 20. The partition plates 17 are movably inserted into the corresponding connecting grooves 15. A plurality of fastening holes 18 are formed on the outer side of the first cylinder 9. A plurality of fasteners 19 are fixedly installed on the top inner wall of the lens cap 20. The plurality of fasteners 19 are symmetrically arranged. The fasteners 19 are movably clamped in the corresponding fastening holes 18. One side of the sealing shell 12 is movably and sealingly abutted against the tapered shell 11. The other side of the sealing shell 12 is movably and sealingly abutted against one side of the ring edge 16. The two sides of the sealing shell 12 are respectively movably and tightly connected to the lens mounting cylinder 6 and the lens cap 20, sealing the connection between the lens mounting cylinder 6 and the lens cap 20 to prevent external water vapor and dust from entering the lens mounting cylinder 6 to contaminate the lens body.

[0029] It should be noted that the connection between the lens cap 20 and the lens mounting cylinder 6 is guided by the clamping of the connecting grooves 15 and the partition plates 17, preventing the lens cap 20 from rotating under force during the process of the fasteners 19 being inserted into the fastening holes 18, resulting in failure to be smoothly clamped. Moreover, the clamping of the connecting grooves 15 and the partition plates 17 improves the installation stability of the lens cap 20 and the lens mounting cylinder 6, preventing relative displacement between the two; the fixed connection between the lens cap 20 and the lens mounting cylinder 6 is realized through the cooperation of the fasteners 19 and the fastening holes 18. The detachable design enables the user to easily remove the lens cap 20, facilitating the cleaning of the lens surface and ensuring clear images.

[0030] As Figure 1 and Figure 2As shown in the figure, a rectangular hole 21 is provided on one side of the recorder housing 1. The rectangular hole 21 is used for installing a display screen. A main board is arranged inside the recorder housing 1. A circuit hole is provided on one side of the main board. The circuit hole is used for electrically connecting the lens body to the main board. A bracket is arranged on the top of the recorder housing 1. A fixing seat 22 is fixedly installed at one end of the bracket. A power supply is arranged inside the fixing seat 22. A plurality of button holes are provided on both the left and right sides of the recorder housing 1. Button monomers are arranged inside the button holes. The main board, the power supply and the buttons are all essential mechanisms for a driving recorder.

[0031] Certainly, the present utility model can also have many other implementation manners. Based on this implementation manner, other implementation manners obtained by those of ordinary skill in the art without any creative work all fall within the scope protected by the present utility model.
