Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of camera modules, in particular to a waterproof camera module. Background Art
[0002] The current vehicle-mounted camera modules all require waterproof design. The current common practice is to wrap the camera module with front and rear metal shells to waterproof it, and put a waterproof ring in the middle of the front and rear metal shells, and then fix and seal it with screws. However, the camera module waterproof ring is generally made of flexible plastic material, and the diameter of the ring is generally 1 mm or less. The picking and alignment method is to pick it up with tweezers and put it into the fiber of the front shell. However, in order to ensure that the waterproof ring has a better waterproof effect when the front and rear shells are locked, the size of the limit will generally be smaller than the size of the waterproof ring, and will be 30% or less smaller than it to ensure that the front and rear shells are locked and squeezed to tighten the waterproof ring. If the operator is not careful and stable enough in this way, the waterproof ring will deviate from the original limit when placing the waterproof ring and locking the front and rear shells, resulting in poor waterproof effect. Utility Model Content
[0003] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a waterproof camera module.
[0004] The purpose of this utility model is achieved through the following technical solutions:
[0005] A waterproof camera module comprises: a front shell and a rear shell; a step groove is arranged on a side of the front shell close to the rear shell; a step bump is arranged on a side of the rear shell close to the front shell; and bonding glue is arranged at the connection between the front shell and the rear shell.
[0006] In one embodiment, the front side of the front shell and the front side of the rear shell are both rectangular.
[0007] In one embodiment, the shape and size of the front side of the rear shell are the same as the shape and size of the front side of the front shell, and the shape and size of the front side of the step groove match the shape and size of the front side of the step protrusion.
[0008] In one embodiment, the length of the front side of the front shell is greater than the length of the front side of the rear shell.
[0009] The step protrusion is arranged at the center of one side of the rear housing close to the front housing.
[0010] In one of the embodiments, the step groove and the step protrusion are electrically conductive to each other.
[0011] In one of the embodiments, a glue dispensing groove is provided on the second step of the step groove, and the bonding glue is applied in the glue dispensing groove.
[0012] In one of the embodiments, a hollowed-out cavity is provided in the inner cavity of the front shell, and the hollowed-out cavity has a rectangular shape. The PCB and electronic components of the camera module are arranged in the front shell.
[0013] In one of the embodiments, the surfaces of the front shell and the rear shell are both coated with anti-rust insulating paint, but the connection between the front shell and the rear shell is not coated.
[0014] In one embodiment, the front shell and the rear shell are both metal structures.
[0015] Compared with the prior art, the utility model has at least the following advantages:
[0016] The waterproof camera module of the utility model can make the front shell and the rear shell fit and bond together through the step groove set in the front shell and the step protrusion in the rear shell, as well as the design of bonding glue. At the same time, the step design can play a role of sealing and waterproofing. The front and rear shells are both metal structures, which are used to improve the anti-static and EMI capabilities of the entire module. The second step of the front shell and the rear shell is a joint, which can be used to prevent and block the glue from flowing into the gap between them after being pressed together, thereby preventing the glue from dripping into the module PCB or electronic components, which can achieve better sealing and waterproofing effects.

[0026] like Figure 1-3 As shown, a waterproof camera module comprises: a front housing 1 and a rear housing 2; a step groove 11 is provided on the side of the front housing 1 close to the rear housing 2; a step protrusion 21 is provided on the side of the rear housing 2 close to the front housing 1; and adhesive glue 3 is provided at the connection between the front housing 1 and the rear housing 2. It should be noted that the side of the front housing 1 away from the rear housing 2 is an integrally formed transparent glass panel, which will not affect the normal use of the camera of the camera module.
[0027] like Figure 1-3As shown, in one embodiment, the front face of the front housing 1 and the rear housing 2 are both rectangular. The shape and size of the front face of the rear housing 2 are the same as the shape and size of the front face of the front housing 1, and the shape and size of the front face of the step groove 11 are consistent with the shape and size of the front face of the step protrusion 21. It should be noted that when the front housing 1 and the rear housing 2 are bonded together, a complete whole is formed.
[0028] like Figure 1-3 As shown, in one embodiment, the length of the front side of the front housing 1 is greater than the length of the front side of the rear housing 2. It should be noted that this design allows the front housing 1 to have space to accommodate the electronic components of the camera module.
[0029] like Figure 1-3 As shown, in one embodiment, the step protrusion 21 is arranged at the center of the side of the rear housing 2 close to the front housing 1. The side of the front housing 1 close to the rear housing 2 is an open design, the step groove 11 is arranged in the opening, and the step groove 11 and the step protrusion 21 are mutually conductive and electrically connected. It should be noted that this design allows the front housing 1 and the rear housing 2 to be electrically connected to each other, so that the electronic components inside them can receive power.
[0030] like Figure 1-3 As shown, in one embodiment, a glue dispensing groove is provided on the second step of the step groove 11, and the bonding glue 3 is applied in the glue dispensing groove. It should be noted that this design can be used to prevent and block the situation that the glue flows into the gap between them after pressing.
[0031] like Figure 1-3 As shown, in one embodiment, a hollow arrangement is made in the inner cavity of the front shell 1, and the hollow shape is rectangular. The PCB and electronic components of the camera module are arranged in the front shell 1.
[0032] like Figure 1-3 As shown, in one embodiment, the surfaces of the front shell 1 and the rear shell 2 are coated with rust-proof insulating paint, but not at the connection between the front shell 1 and the rear shell 2. It should be noted that this design can be used for insulation and rust prevention, and only the connection is left uncoated so that the front and rear shells can be electrically conductive.
[0033] like Figure 1-3 As shown in one embodiment, the front housing 1 and the rear housing 2 are both metal structures. It should be noted that this design can improve the anti-static and EMI capabilities of the entire module.
[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
