Description

Technical Field

[0001] The utility model relates to the field of vehicle-mounted cameras, in particular to a pre-assembled clamping structure of front and rear shells of a vehicle-mounted camera. Background Art

[0002] A car camera is a device installed on a vehicle to monitor and record the conditions inside and outside the vehicle. These cameras are usually high-resolution and high-definition, which can capture clear images and videos. Car cameras can be used for a variety of purposes, such as security monitoring, driving recorders, reversing images, etc.

[0003] The housing of a vehicle camera is usually composed of a front and a rear housing. In order to assemble the front and the rear housing, a pre-assembled snap-fit ​​structure of the front and the rear housing of the vehicle camera is required.

[0004] The current pre-assembled snap-fitting structure of the front and rear shells of the camera is usually set as a plastic snap-fitting structure, which uses its own elasticity to bite each other. In order to ensure the sealing, a large number of snap-fittings are set, and in order to ensure the accuracy of the installation, additional positioning columns are required to position the front and rear shells to ensure the alignment of the snap-fitting mechanism, and the mold setting is relatively complicated; on the other hand, cameras such as reversing images and 360 images in vehicle-mounted cameras are usually set on the outside of the vehicle body. In rainy weather, although the shell has been waterproofed, rainwater will still enter the shell after long-term use. The current snap-fitting mechanism is not provided with a drainage structure, which makes it easy for water to enter the snap-fitting structure. After long-term use, rainwater will corrode the snap-fitting structure, causing the snap-fitting mechanism to loosen. Therefore, a pre-assembled snap-fitting structure of the front and rear shells of a vehicle-mounted camera is proposed to solve the above problems. Utility Model Content

[0036] Reference Figure 3-Figure 4 , a sliding block 7 is slidably connected inside the limit seat 6, and the front end of the outer wall of the side of the limit seat 6 is set to a conical surface. The front end of the outer wall of the side of the sliding block 7 is set to a conical surface. The sliding block 7 is adapted to the shape of the inner cavity of the limit seat 6. The limit seat 6 limits the sliding block 7 to only slide forward and backward along the inner wall of the limit seat 6. The sliding block 7 is made of iron and can be adsorbed by a strong magnet. A limited column groove 8 is provided inside the sliding block 7. The limited column groove 8 is provided with three groups, which are evenly distributed in an annular shape inside the sliding block 7. A limited ball 9 is slidably connected inside the limited column groove 8. When the front of the sliding block 7 contacts the front inner wall of the limit seat 6, the inclined surface of the inner wall of the limit seat 6 will push the limited ball 9 to move inward and make the limited ball 9 protrude from the inner side of the limited column groove 8. A spring groove 10 is provided on the back of the sliding block 7. The spring groove 10 The front inner wall is elastically connected with a fixed round block 5 through a limit spring 11, one end of the limit spring 11 is fixedly connected to the front inner wall of the spring groove 10, and the other end of the limit spring 11 is fixedly connected to the front of the fixed round block 5. When the sliding block 7 is not subjected to force, the limit spring 11 will push the sliding block 7 to move forward through the spring groove 10. The sliding block 7 is slidably connected with a card needle 12 inside, and the outer periphery of the card needle 12 passes through and is slidably connected to the inside of the limit seat 6. The card needle 12 and the limit seat 6 can play the role of positioning columns to keep the position of the front shell 1 and the rear shell 3 fixed. A card groove 13 is provided on the outer periphery of the card needle 12, and the inner side of the limit ball 9 is clamped in the inside of the card groove 13 to fix the card needle 12. The front of the card needle 12 is fixedly connected with a fixed block 14, and the front of the fixed block 14 is fixedly connected to the front inner wall of the front shell 1.

[0037] Reference Figure 3-Figure 4A waterproof baffle 15 is fixedly connected to the front of the limit seat 6, and the outer periphery of the waterproof baffle 15 is set to a conical surface. The conical surface of the waterproof baffle 15 is larger at the front and smaller at the back. When there is water, the waterproof baffle 15 will prevent water from entering the hole on the limit seat 6. The waterproof baffle 15 and the bottom surface of the fixed block 14 are both fixedly connected to a drainage cone block 16. The bottom of the drainage cone block 16 is set to a pointed end to avoid water gathering and guide water to be discharged from the bottom of the drainage cone block 16. The fixed block 14 is set to a frustum with a small front and a large back on the inclined surface to prevent water from contacting the card pin 12.

[0038] When the locking pin 12 is in the locked position, the locking pin 12 is pushed back to the locking groove 13, and the locking pin 12 is fixed to the locking groove 13, thereby fixing the front shell 1 and the rear shell 3. When one wants to prevent the locking part from being corroded by water, rainwater enters the shell through the gap, falls on the limit seat 6 and the fixing block 14, and slides down along the conical surfaces of the limit seat 6 and the fixing block 14. The water on the limit seat 6 will be blocked by the waterproof baffle 15, fall along the groove, and contact the drainage cone block 16, and be discharged downward under the guidance of the drainage cone block 16, thereby reducing the probability of the locking needle 12 contacting water and reducing rainwater corrosion.
