Referring to fig. 3 to 5, fig. 3 is a schematic overall structure diagram of an embodiment of a focusing unit of the present application, fig. 4 is a schematic exploded structure diagram of the focusing unit in the embodiment of fig. 3, and fig. 5 is a schematic cross-sectional view of the focusing unit structure in the embodiment of fig. 3. The focusing unit 100 in this embodiment is used in a camera module to realize the focusing function of the camera module. The existing camera module can be used in electronic equipment such as mobile phones, tablet computers, notebook computers, wearable equipment and the like. In the present embodiment, the focusing unit 100 includes a supporting member 110, a variable focal length lens 120 and a reinforcing member 130. It should be noted that the terms "comprises" and "comprising," and any variations thereof, in the embodiments of the present application, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or may alternatively include other steps or elements inherent to such process, method, article, or apparatus.

Specifically, the support 110 in the present embodiment includes a top plate 111 and a side plate 112. Wherein the top plate 111 is connected with the side plate 112. Alternatively, the top plate 111 and the side plate 112 may be a unitary structure made of the same material, such as glass or silicon. The side plate 112 is generally used for connecting with a camera module, and the top plate 111 may be covered with a layer of piezoelectric ceramic, which is connected with an external control circuit and can be deformed under the driving of voltage. The thickness of the top plate 111 is generally small.

In this embodiment, the middle position (labeled 1111 in the figure) of the top plate 111 may be a circular transparent lens, or a light-transmitting area without piezoelectric ceramics, which is used as a light-entering hole of the focusing unit 100.

Optionally, the variable focus lens 120 in this embodiment includes an elastic transparent body 121 and a supporting plate 122, the elastic transparent body 121 is disposed in the accommodating space 101 between the supporting plate 122 and the top plate 111, two opposite side surfaces of the elastic transparent body 121 are respectively connected to the supporting plate 122 and the top plate 111, optionally, the elastic transparent body 121 may be made of flexible resin or silica gel, and two opposite side surfaces of the elastic transparent body 121 are respectively bonded and fixed to the supporting plate 122 and the top plate 111.

When the relative position between the supporting plate 122 and the top plate 111 changes (for example, the piezoelectric ceramic on the top plate 111 deforms under the action of voltage), the two opposite side surfaces of the elastic transparent body 121 are respectively bonded and fixed with the supporting plate 122 and the top plate 111, so that the two opposite side surfaces can change along with the deformation of the top plate 111, the elastic transparent body 121 is equivalent to a transparent lens, and after the deformation, the radian or the shape of the lens changes, so that the focusing function is realized.

However, in the stress test, since the thickness of the top plate 111 is small, the joint between the top plate 111 and the side plate 112 is weak, and in addition, in the drop test, the elastic transparent body 121 is subjected to an inertial pulling force in the thickness direction (X direction in the drawing), and the joint between the top plate 111 and the side plate 112 is often broken.

In view of this, the focusing unit 100 in the embodiment of the present application is provided with a reinforcement 130 at the connecting position of the top plate 111 and the side plate 112. The reinforcing member 130 is connected to the top plate 111 and the side plate 112, respectively, and is used to improve the tensile stress at the connection position of the top plate 111 and the side plate 112, improve the connection reliability of the top plate 111 and the side plate 112, strengthen the anti-falling capability of the supporting member, and further improve the structural reliability of the focusing unit.

Optionally, referring to fig. 4 and fig. 6 together, fig. 6 is a schematic structural view illustrating a supporting member and a reinforcing member of the focusing unit in the embodiment of fig. 4. The reinforcing members 130 in this embodiment are uniformly and continuously disposed along the connecting position of the top plate 111 and the side plate 112. Alternatively, the reinforcing member 130 may be a rubber strip, and the rubber strip is bonded to the connecting position of the top plate 111 and the side plate 112. The adhesive tape may be formed by dispensing along the periphery of the connecting position of the top plate 111 and the side plate 112. It should be noted that. All directional indications (such as up, down, left, right, front, and rear … …) in the embodiments of the present application are only used to explain the relative positional relationship between the components, the movement, and the like in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indication is changed accordingly.

Optionally, referring to fig. 7 together, fig. 7 is a schematic cross-sectional view of the focusing unit at a-a in the embodiment of fig. 3, and optionally, the maximum size of the contact between the stiffener 130 and the top plate 111 and the side plate 112 ranges from 20x20um to 300x300 um. The maximum dimension of the stiffener contacting the top plate and the side plate as referred to herein means the dimension of the width W and the thickness T in the drawing, that is, the width W is between 20um and 300um, and the thickness T is also between 20um and 300 um. The adhesive tape is formed by solidification after dispensing, so the cross-sectional dimension after molding may be irregular, such as triangle-like, rectangle-like, or ellipse-like, and the illustration is only a simplified triangle.

Through glue analysis of different Young's moduli, Young's modulus parameters of the glue are increased progressively, so that the stress is reduced more, and the improvement effect is larger. Alternatively, the Young's modulus of the adhesive strip of the stiffener 130 in the embodiments of the present application may range between 2-5 GPa. The following experiments in the examples of the present application were conducted using an adhesive tape with a Young's modulus of 3.6GPa as an example. When the maximum contact size of the reinforcing part 130 (i.e. the rubber strip) with the top plate and the side plate is 290 × 290um, the stress peak value can be reduced to about 1%; when the maximum size of the contact between the reinforcing piece 130 and the top plate and the side plate is 200 x 200um, the stress peak value can be reduced to about 2 percent; when the maximum size of the contact between the reinforcing piece 130 and the top plate and the side plate is 90 x 90um, the stress peak value can be reduced to about 20 percent; when the maximum size of the contact between the reinforcing member 130 and the top plate and the side plate is 40 × 40um, the stress peak can be reduced to about 42%. Referring to fig. 8, fig. 8 is a stress simulation diagram of young's modulus glue under different glue strip sizes.

The maximum size (i.e., the amount of glue applied) of the contact between the reinforcing member 130 and the top plate and the side plates cannot be increased infinitely, the width of the glue strip is increased, and negative effects are generated, and the overall performance of the focusing unit 100 is affected by considering the parameters of the focusing unit 100 such as the Focal Power (which is equal to the difference between the convergence of the image-side light beam and the convergence of the object-side light beam, which is indicative of the ability of the optical system to deflect light rays) and the wavefront difference (which is defined by the deviation between the actual wavefront and the ideal wavefront in an unbiased state). Referring to FIG. 9, FIG. 9 is a graph showing power simulations for different strip sizes; FIG. 10 is a simulated plot of wavefront difference for different bead sizes. As can be seen from fig. 9 and 10, as the maximum size of the reinforcement 130 in contact with the top and side panels increases, the optical power becomes lower and the wave front difference becomes larger, both of which progress toward the deterioration of performance as the maximum size of the reinforcement 130 in contact with the top and side panels increases.

When the consideration of the optical parameters (including but not limited to the optical power and the wavefront difference) of the focusing unit 100 is combined, the ratio of the passing rate is significantly improved through the reliability test of the focusing unit 100. Referring to fig. 11, fig. 11 is a trend diagram of the reliability test result of the focusing unit. When the maximum size of the contact between the reinforcing member 130 and the top plate and the side plate is 90 × 90um, the Pass rate (Pass rate) of reliability can be improved to more than 95%, and the production requirement is met. Thus, the maximum dimension of the stiffener in contact with the top and side panels may alternatively range from 60x60um to 110x110 um.

Referring to fig. 12, fig. 12 is a schematic view illustrating a deformation caused by a force when the focusing unit is engaged with the lens holder of the camera module. Wherein, the curb plate 112 and the camera module lens support 201 of support piece 110 are connected, and at the in-process of drop test, roof 111 can take place deformation under the effect that receives elastic transparent body 121 inertia pulling force, because the existence of reinforcement 130, can play the purpose of the effort between buffering roof 111 and the curb plate 112, prevent that roof 111 and curb plate 112's hookup location department from taking place the fracture.

The focusing unit 100 in the present embodiment may also include a support member 110, a variable focus lens 120, and a reinforcement member 130. The support 110 includes a top plate 111 and a side plate 112. The top plate 111 is connected to the side plate 112, and in this embodiment, the variable focus lens 120 includes an elastic transparent body 121 and a supporting plate 122.

The division of the top plate 111 should not limit the protection scope of the present invention.
