Abstract
Description

[0002] In order to facilitate the assembly of the periscope camera module, the cross-section of the carrier of the periscope camera module is mostly in a "U" shape to place the lens. After the lens is placed on the carrier, the two are fixed by glue; and the shape of the carrier in the periscope camera module makes it easy for its opening to deform outward, which further causes the glue at the connection position between the lens and the carrier to crack, resulting in the separation of the lens and the carrier.
[0003] Therefore, grooves are provided on both sides of the carrier opening of the existing periscope camera module, and a metal clip is added. Protrusions matching the grooves are provided at both ends of the metal clip. After the lens is assembled and fixed by gluing, the metal clip is buckled at the opening of the carrier, and the protrusions at both ends are arranged in the grooves on both sides of the carrier opening, and fixed by glue to reduce the phenomenon of glue cracking and failure. However, due to the added metal clip, not only the overall thickness of the periscope camera module is increased, but also a process of bonding the metal clip is added, which reduces the efficiency of assembling the periscope camera module.

[0033] See also Figure 1-Figure 7 In a first aspect of the present application, a periscope camera barrel assembly (hereinafter referred to as a barrel assembly) is provided, which includes a barrel 521 and a limit member 522.
[0034] The lens barrel 521 is mostly a tubular member, and the inner cavity of the lens barrel 521 is mostly a cylindrical cavity for installing lenses. The shape of the lens barrel 521 can be set according to needs. The inner cavity of the lens barrel 521 of the present application is provided with a plurality of lenses (not shown).
[0035] At least two limiting members 522 are respectively arranged on both sides of the outer wall of the lens barrel 521, and the limiting member 522 includes a connecting portion 522a and a limiting portion 522b. One end of the connecting portion 522a is connected to the outer wall of the lens barrel 521, and the other end of the connecting portion 522a is connected to a part of the side wall of the limiting portion 522b. The lens barrel 521 and the limiting member 522 are integrally formed, wherein the shape of the connection between the connecting portion 522a and the limiting portion 522b is "T"-shaped. In other embodiments, the shape of the connection between the connecting portion 522a and the limiting portion 522b is "L"-shaped. This arrangement can also have a limiting effect on the lens barrel 521.
[0036] See also Figure 2 , Figure 4 and Figure 5 The other end of the connecting portion 522a is connected to a portion of the side wall of the limiting portion 522b, that is, when the lens barrel assembly 520 is set on the carrier 510, the limiting portion 522b of the limiting member 522 can be at least partially set in the grooves on both sides of the opening of the carrier 510. When the opening of the carrier 510 tends to open, the limiting portions 522b on both sides of the lens barrel 521 abut against the side walls of the groove, thereby limiting the deformation of the opening of the carrier 510.
[0037] The lens barrel 521 and the stopper 522 are integrally formed, for example, by injection molding or die casting. In addition, when the lens barrel 521 is set in the carrier 510, the stopper 522 can cooperate with the grooves on both sides of the opening of the carrier 510. Therefore, after applying glue to the carrier 510, glue can be applied to the grooves on both sides of the opening of the carrier 510 immediately, and then the lens barrel 521 is aligned with the carrier 510 and pressed down. At the same time, the bottom end of the lens barrel 521 cooperates with the glue in the carrier 510, and the bottom end of the stopper 522b will also just cooperate with the glue in the grooves on both sides of the opening of the carrier 510. That is, when the lens barrel 521 is installed on the carrier 510, only one gluing operation of the lens barrel 521 and the carrier 510 is required, and there is no need to perform the glueing operation of the lens barrel 521 and the carrier 510. Fig. 9 The prior art shown in the figure is to bond the lens barrel 521 to the carrier, and then bond the metal clamps 600 to the grooves on both sides of the opening of the carrier 510. The lens barrel 521 of this embodiment can be quickly set on the carrier 510 and bonded quickly, while resisting deformation of the carrier 510, with fewer bonding steps, and high assembly efficiency of the periscope camera module.
[0038] See also Figure 1 and Figure 2 In some embodiments, the connection portion 522a of the limiting member 522 is connected to the middle of the side wall of the limiting portion 522b. When the limiting portion 522b abuts against the grooves on both sides of the opening of the carrier 510, since the connection portion 522a is connected to the middle position of the side wall of the limiting portion 522b, the limiting portions 522b located on both sides of the connection portion 522a are subjected to balanced force, and the torque when subjected to force is small, resulting in stress fracture or deformation that is not likely to occur between the connection portion 522a and the limiting portion 522b. The limiting member 522 has high strength, is not easy to be damaged, has a strong limiting ability on the opening of the carrier 510, and the opening of the carrier 510 is not easy to deform.
[0039] See also Figure 1 , Figure 2 and Figure 3 In some embodiments, the connecting portion 522a is arranged along the circumference of the lens barrel 521. At this time, the height of the connecting portion 522a is high, and the connecting area between the connecting portion 522a and the outer wall of the lens barrel 521 is large. The connection strength between the connecting portion 522a and the lens barrel 521 is high and the deformation resistance is strong, and the connecting portion 522a is not easily damaged by force.
[0040] For ease of understanding, see Figure 2 , wherein the direction of the optical axis of the lens barrel 521 is the first direction C, see Figure 3, the height direction of the lens barrel 521 is the second direction D, and the height direction of the connecting portion 522a is parallel to the second direction D. When the strength of the connecting portion 522a is increased, the force required to damage the stopper 522 is greater, and the stopper 522 can resist greater pressure from the carrier 510, that is, the limiter 522's ability to limit the deformation at the opening of the carrier 510 is further improved. Of course, in the case where the strength of the stopper 522 to resist the deformation of the opening of the carrier 510 is overflowing or too large, the height of the connecting portion 522a and the stopper 522b can be reduced accordingly during the design stage to reduce the overall height and weight of the lens barrel assembly 520.
[0041] See also Figure 1 and Figure 3 In some embodiments, the connecting portion 522a, the limiting portion 522b and the top of the lens barrel 521 are flush. At this time, the limiting member 522 no longer protrudes from the lens barrel 521, and the height of the lens barrel 521 and the limiting member 522 are kept consistent, which facilitates the assembly of the lens barrel assembly 520. Compared with the prior art, it saves the trouble of Fig. 9 The metal clamp 600 shown saves cost and further reduces the height of the lens barrel assembly 520 .
[0042] See also Figure 4-Figure 7 Since the stress between the stopper 522 and the groove at the opening of the carrier 510 is mainly concentrated on the upper part of the lens barrel 521, the height of the stopper 522b can be relatively reduced to a certain extent to reduce the weight of the entire lens barrel assembly 520, and the height of the connecting portion 522a is the same as the height of the stopper 522b. The thickness of the connecting portion 522a can be only half of the height of the lens barrel 521. The carrier 510 is also provided with an avoidance groove 512 for accommodating the connecting portion 522a, see Figure 3In some embodiments, the limiting member 522 further includes a guiding portion 523, which is connected to the outer wall of the lens barrel 521. The guiding portion 523 and the connecting portion 522a of a limiting member 522 are located in the same plane. It can be understood that part of the guiding portion 523 can be slidably matched with the avoidance groove 512 on the carrier 510. When the lens barrel assembly 520 is set on the carrier 510, if the central axis of the lens barrel assembly 520 and the central axis of the carrier 510 are not in the same vertical plane, then among the multiple limiting members 522, the guiding portion 523 of at least one limiting member 522 will first be slidably matched with the avoidance groove 512 at the corresponding position and play a guiding role, thereby facilitating the entire lens barrel 521 to be quickly and accurately plugged into the carrier 510, thereby improving the assembly efficiency of the lens barrel assembly 520 and the carrier 510. Of course, the top end of the guide portion 523 can also be connected to the bottom end of the connecting portion 522a. At this time, the guide portion 523 is connected to both the lens barrel 521 and the connecting portion 522a, which further increases the connection area between the limit member 522 and the lens barrel 521. The limit member 522 is not easily separated from the lens barrel 521 when subjected to external force, thereby improving the overall strength of the lens barrel assembly 520.
[0043] See also Figure 1-Figure 3 In some embodiments, the outer wall of the lens barrel 521 is provided with two stoppers 522, and the two stoppers 522 are symmetrically arranged on the left and right sides of the lens barrel 521. In other embodiments, the outer wall of the lens barrel 521 may be provided with three stoppers 522, one of which is located in the middle of one side of the optical axis of the lens barrel 521, and the other two stoppers 522 are located at both ends of the other side of the optical axis of the lens barrel 521. The three stoppers 522 present a triangular structure, and the structure of the lens barrel assembly 520 is stable. In other embodiments, the outer wall of the lens barrel 521 may be provided with four stoppers 522, and it is sufficient to ensure that at least one stopper 522 is provided on both sides of the optical axis of the lens barrel 521. The more the number of stoppers 522, the more the lens barrel assembly 520 restricts the opening of the carrier 510, and the ability to resist deformation of the carrier 510 is enhanced.
[0044] In some embodiments, two stoppers 522 are disposed on the outer wall of the lens barrel 521, and the connecting portions 522a of the two stoppers 522 are both connected to the middle of the outer wall of the lens barrel 521. That is, when the lens barrel assembly 520 is disposed on the carrier 510, the limiting position of the stoppers 522 on the carrier 510 is located in the middle of the side wall of the carrier 510, and the stress of the carrier 510 is relatively balanced, and it is not easy for the two ends of the carrier 510 in the first direction C to be severely deformed, and the anti-deformation ability is good.
[0045] See also Figure 4-Figure 8According to a second aspect of the present application, a periscope camera module is provided, including a shell 10 and a reflection component 20, a circuit component 40, a filter component 30 and a lens component 50 arranged in the shell 10, wherein the lens component 50 includes the above-mentioned periscope camera barrel assembly 520, a lens group 530 arranged in the barrel 521, a carrier 510 for supporting the barrel 521 and a driver for driving the carrier 510 to move, the carrier 510 is provided with a mounting groove, and the opposite side walls of the mounting groove are provided with limiting grooves 511 corresponding to the limiting members 522 one by one, and the limiting portion 522b is at least partially located in the limiting groove 511.
[0046] The reflective assembly 20 is arranged on one side of the lens barrel 521. The reflective assembly 20 is located at the front end of the lens assembly 50. The reflective assembly 20 includes a bracket and a prism. The prism is arranged in the bracket. The bracket has a light inlet and a light outlet. The light outlet is arranged corresponding to the optical axis of the lens group 530 in the lens barrel 521. The opening directions of the light inlet and the light outlet are different. The prism is arranged obliquely between the light inlet and the light outlet to reflect the light entering from the light inlet to the light outlet. In addition, the periscope camera module forms an "L"-shaped path through the arrangement of the prism.
[0047] The filter assembly 30 is disposed on the other side of the lens barrel 521. The filter assembly 30 includes a filter. The filter is disposed corresponding to the lens group 530. The filter is used to selectively transmit the imaging light after passing through the lens group 530, for example, to allow visible light to pass through, while blocking infrared light or ultraviolet light. In other embodiments, an infrared filter film can be plated on the last lens in the lens group 530 (the last lens close to the circuit assembly 40). This method has the same light filtering effect, thereby eliminating the filter and reducing the size of the entire periscope camera module.
[0048] The circuit assembly 40 is disposed behind the filter assembly 30. The circuit assembly 40 is mainly provided with a chip. The circuit assembly 40 is used to receive the imaging light filtered by the filter assembly 30 and convert it into a signal for transmission. The structural features and working principles of the reflective assembly 20, the circuit assembly 40, and the filter assembly 30 can all be completely referred to the prior art and Figure 8 , the optical direction of the entire periscope module: first, the light from the external environment enters from the light inlet of the bracket, and then passes through the light outlet after being reflected by the prism, and then passes through the lens group 530 in the lens barrel 521. After the light passes through the lens barrel 521, it is filtered by the light filter assembly 30, and finally, the light is obtained by the circuit assembly 40. The optical signal is converted into an electrical signal and processed to generate an image. It is very easy for those skilled in the art to understand, so there is no need to elaborate here. Obviously, the periscope camera module can be assembled with reference to the working principle of the lens barrel assembly 520 in the aforementioned embodiment, and the beneficial technical effects of the above-mentioned lens barrel assembly 520 can also be obtained.
