Description

Technical Field

[0001] The utility model relates to the technical field of automotive cameras, and more specifically, it relates to a waterproof connection structure for a camera. Background Art

[0002] In the existing technology, the rear cover of the camera and the wire harness are connected by threads. The mold needs to have a thread-cutting structure, which makes the mold relatively complex. Moreover, it protrudes relatively high from the rear cover and has a large volume, so its adaptability is poor when installed in a narrow space of the vehicle body and it is easy to interfere with components.

[0003] In order to ensure reliable waterproof performance and pull-off force, imported glue is needed for fixation, which increases the procurement cycle and delivery risk. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a waterproof connection structure for a camera, specifically a front cover waterproof wire harness that can be quickly disassembled and has a small volume.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A waterproof connection structure for a camera includes a rear cover, a lens holder, a front cover and a rotary buckle.

[0006] The rear cover has a box structure with one side open. A fixing hole is provided on one side of the rear cover far from the opening. A fixing part is arranged in the fixing hole, and a limiting part is arranged on one side of the fixing part close to the opening.

[0007] The lens holder is arranged at the opening of the rear cover and completely seals the opening of the rear cover. An installation hole is provided on the lens holder.

[0008] The front cover is arranged in the installation hole, and the front cover completely covers the installation hole and is hermetically connected to the installation hole.

[0009] The rotary buckle is detachably and hermetically arranged in the fixing hole. A clamping part that abuts against the limiting part is arranged on the outer side wall of one end of the rotary buckle close to the rear cover. An external hexagon is arranged on the outer wall of the end of the rotary buckle far from the rear cover. An embedding ring is arranged at one end of the external hexagon close to the rear cover. The embedding ring is embedded in the fixing hole, and a sealing glue is arranged in the gap between the embedding ring and the fixing hole.

[0010] Through the sealing arrangement of the lens holder and the rear cover, it can be ensured that the inside is dry. Also, through the front cover hermetically sealing the camera arranged on the lens holder, the function of the camera is realized. Finally, through the setting of the fixing hole on the rear cover and the rotary buckle, the volume can be reduced after the wire harness is installed because the threaded section is removed, resulting in a smaller volume of the rotary buckle. Finally, by embedding the embedding ring in the fixing hole, the best sealing effect can be ensured, and together with ordinary sealing glue, the effect of not leaking water can be ensured.

[0011] The present utility model is further configured as follows: positioning posts are provided at the four corner positions on the side of the lens holder close to the rear cover, and positioning grooves matching the positioning posts are provided at the four corner positions on the outer side wall of the side of the rear cover close to the lens holder.

[0012] Through the arrangement of the positioning posts and the positioning grooves, the originally relatively large-sized connection method can be changed to an integrated connection, thereby reducing the problem of large volume occupation.

[0013] The present utility model is further configured as follows: a waterproof groove is provided on the side of the lens holder close to the rear cover and is arranged along its circumferential direction, and a sealing gasket is arranged in the waterproof groove.

[0014] After the sealing gasket is embedded in the waterproof groove, when the lens holder and the rear cover are tightly connected, the sealing gasket can be pressed tightly, thereby ensuring that the sealing gasket can effectively achieve the sealing effect.

[0015] The present utility model is further configured as follows: two symmetrically arranged fixing parts are provided in the fixing hole, the fixing parts are in a quarter-ring shape, and limiting parts are arranged at both ends of the fixing parts.

[0016] By arranging the limiting parts at both ends of the fixing parts, the limiting effect of the limiting parts on the clamping parts can be ensured.

[0017] The present utility model is further configured as follows: a waterproof gasket is further arranged between the embedded ring and the fixing part.

[0018] By arranging the waterproof gasket between the embedded ring and the fixing part, the waterproof effect of the wire harness position can be enhanced.

[0019] In summary, the present utility model has the following beneficial effects:

[0020] 1. Through the sealing arrangement of the lens holder and the rear cover, the interior can be ensured to be dry. And by sealing the camera with the front cover and arranging it on the lens holder to realize the function of the camera. Finally, through the arrangement of the fixing hole and the snap button on the rear cover, the volume change can be realized after the wire harness is installed because the volume of the snap button is reduced due to the removal of the threaded section fit. Finally, by embedding the embedded ring in the fixing hole, the maximum sealing effect can be ensured, and together with ordinary sealant, the effect of not leaking water can be ensured.

[0021] 2. Use domestic ordinary glue for sealing, optimize the supply chain structure, and reduce the delivery risk;

[0022] 3. Reduce the volume size and improve the installation adaptability;

[0023] 4. The rear cover and the wire harness are connected by a quick snap button, and the mold does not require a threading structure, reducing the mold cost. BRIEF DESCRIPTION OF THE DRAWINGS
