Description

Technical Field

[0001] The utility model relates to the technical field of motor lenses, in particular to a motor lens protective film. Background Art

[0002] Motor lens refers to a lens that integrates a motor inside the lens to achieve autofocus and zoom functions. It is widely used in various electronic imaging devices such as smartphones, digital cameras, and camcorders. Driven by the motor, the motor lens can quickly adjust the position of the lens to change the focal length and achieve fast autofocus and optical zoom. The lens motor is susceptible to dust and dirt, which may enter the motor and affect its normal operation. Therefore, mounting a protective film on the surface of the motor can effectively isolate external dust and dirt, keep the motor clean, and extend its service life. However, the electronic module of the lens motor is prone to shaking during use, which affects the stability and normal operation of the device. Utility Model Content

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0022] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] See also Figures 1 to 3 A motor lens shown in a preferred embodiment of the present application includes a high-transmittance film 1, a hard foam frame 2, an antistatic silicone layer 3 and a soft foam layer 4. One side of the hard foam frame 2 is arranged around the high-transmittance film 1. The antistatic silicone layer 3 is arranged on the other side of the hard foam frame 2. The soft foam layer 4 is arranged on the high-transmittance film 1, the soft foam layer 4 and the hard foam frame 2 are located on the same surface of the high-transmittance film 1, the thickness of the soft foam layer 4 is greater than the thickness of the hard foam frame 2, and the soft foam layer 4 is located in the hard foam frame 2.

[0024] Since the electronic module of the lens motor is prone to shaking during use, thus affecting the stability and normal operation of the device. Therefore, according to the solution of the embodiment of the utility model, a soft foam layer 4 having a thickness greater than that of the hard foam frame 2 is provided on the high-transmittance film 1 to form a local protrusion to support the electronic module in the middle of the motor, so that the soft foam layer 4 plays a buffering role, can effectively fix the electronic module to prevent it from shaking, thereby ensuring the stability and normal operation of the device; and the antistatic silicone layer 3 is attached to the periphery of the motor housing, so that the high-transmittance film 1 covers the surface of the motor to play a role in dust protection.

[0025] The following is a detailed description with specific embodiments:

[0026] See also Figure 2 and Figure 3A double-sided adhesive layer 5 for bonding is provided between the high-transmittance film 1 and the hard foam frame 2, between the hard foam frame 2 and the antistatic silicone layer 3, and between the high-transmittance film 1 and the soft foam layer 4. Specifically, in this embodiment, the double-sided adhesive layer 5 between the high-transmittance film 1 and the hard foam frame 2 is a first adhesive layer 51, the double-sided adhesive layer 5 between the hard foam frame 2 and the antistatic silicone layer 3 is a second adhesive layer 52, and the double-sided adhesive layer 5 between the high-transmittance film 1 and the soft foam layer 4 is a third adhesive layer 53.

[0027] See also Figure 1 and Figure 2 The high-transmittance film 1, the hard foam frame 2 and the antistatic silicone layer 3 are all provided with tearing handles 6 at corresponding positions, and each tearing handle 6 is bonded together by a double-sided adhesive layer 5. Since one side of the tearing handle 6 on the antistatic silicone layer 3 is still sticky after being bonded to the tearing handle 6 on the hard foam frame 2, in order to facilitate the subsequent use of the tearing handle, a white original film 61 is attached to the other side of the tearing handle 6 on the antistatic silicone layer 3 to facilitate subsequent film tearing.

[0028] When the protective film in this embodiment is processed and manufactured, the first step is to die-cut the soft foam layer 4 and the third adhesive layer 53 to form a first semi-finished product, the second step is to die-cut the white original film 61, the antistatic silicone layer 3, the second adhesive layer 52, the hard foam frame 2, the first adhesive layer 51 and the high-transmittance film 1 to form a second semi-finished product, and the last step is to use a mounting machine to mount the first semi-finished product and the second semi-finished product of the first two steps to form a finished protective film.

[0029] See also Figure 1 and Figure 2 The antistatic silicone layer 3 is a frame-shaped structure corresponding to the hard foam frame 2, and the inner corners of the antistatic silicone layer 3 are chamfered. By setting the chamfers on the inner corners of the antistatic silicone layer 3, it can correspond to the shape of the motor housing periphery, increase the attachment area of ​​the antistatic silicone layer 3, and thus improve the firmness of the protective film mounting.

[0030] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] 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.
