[0037] First Embodiment

[0038] Please refer to Figures 1-10 One embodiment of the present invention provides a lens carrier 100, including a first outer shell 11 and a second outer shell 12. The first outer shell 11 is used to fix a lens module 200. The second outer shell 12 includes an outer shell body 121 and a deformable part 122 disposed on the outer shell body 121. The first outer shell 11 is provided with a mounting channel 111, which is used to interfere with the deformable part 122 to assemble the outer shell body 121 of the second outer shell 12 and the first outer shell 11.

[0039] Specifically, the lens module 200 is fixed on the lens carrier 100, which can protect the lens module 200 to a certain extent, and the lens carrier 100 is modularized into the first shell 11 and the second shell 12, which can facilitate the installation and fixation of the lenses and other components in the lens module 200. The assembly of the first shell 11 and the second shell 12 in the prior art is usually through rigid connection, for example, the threaded locking adopted in the prior art, the threaded connection of the screw and the threaded hole to realize the fixation of the two, however, this way has a relatively complex assembly process, and in the embodiment, the installation channel 111 is arranged on the first shell 11, the deformable part 122 on the second shell 12 is inserted into the installation channel 111 and is compressed to deform, the deformable part 122 supports the inner wall of the installation channel 111 due to the tendency to return to the original shape, thereby stably connecting the deformable part 122 and the installation channel 111.

[0040] In the installation operation process, only the installation channel 111 of the first shell 11 and the deformable part 122 of the second shell 12 need to be aligned, and the deformable part 122 is squeezed into the installation channel 111 by artificial or mechanical arm to complete the assembly, and in the prior art, the assembly between the shells adopts screw locking, in which the screw is not deformable, so that the screw needs higher precision when being inserted into the threaded hole, the matching degree of the screw and the threaded hole needs to be confirmed in advance, and even the relative positions of the two need to be adjusted, and then the threaded rod is inserted and tightened. In addition, if the assembly is performed by laser welding, the operation, debugging, parameter setting and fault elimination of the laser welding equipment are very complex, which requires higher professional skills and longer working time. During the laser welding process, the laser power, spot size, welding speed and other parameters need to be accurately controlled, and any slight change in any parameter may affect the welding quality. Therefore, the operator needs to have rich experience and professional knowledge to ensure the stability and quality of the welding process. Compared with the prior art, the assembly method of the embodiment shortens the assembly time and simplifies the process flow, improves the production efficiency and reduces the cost.

[0041] In the embodiment, the installation channel 111 includes a fixed segment 111a and a limiting segment 111b, the limiting segment 111b is an arc with a central angle > 0° and ≤ 90°, the fixed segment 111a is used to fix the deformable part 122, and the limiting segment 111b is used to bend the deformable part 122 to make the deformable part 122 and the installation channel 111 clamped.

[0042] Specifically, the deformable part 122 first enters from the fixed section 111a, which has a certain length to ensure that the deformable part 122 is preliminarily fixed, and then continues to be inserted along the length direction of the fixed section 111a, and then reaches the limiting section 111b. Since the limiting section 111b is not coaxial with the fixed section 111a but has a special shape, the deformable part 122 is forced to turn after entering the limiting section 111b. The deformation of the deformable part 122 is not only compression to the inside but also bending to the outside, so that the end of the deformable part 122 is clamped with the limiting section 111b, further limiting the deformable part 122 from coming out of the mounting channel 111, and ensuring the connection stability of the first shell 11 and the second shell 12. The arc-shaped limiting section 111b is beneficial to the guidance of the deformable part 122, avoiding the too sharp corner to block the extension of the deformable part 122. The limiting section 111b is further arranged as an arc with a central angle > 0° and ≤ 90°, so that the limiting section 111b forms an acute angle with the fixed section 111a, and the outlet of the limiting section 111b for the extension of the deformable part 122 is deviated downward, that is, opposite to the direction of the extension of the deformable part 122 into the limiting section 111b. In this way, the deformable part 122 can be sufficiently limited.

[0043] In the embodiment, the total length of the mounting channel 111 is greater than the length of the deformable part 122.

[0044] Specifically, the total length of the mounting channel 111 is the sum of the length of the fixed section 111a and the length of the limiting section 111b. When the total length of the mounting channel 111 is greater than the length of the deformable part 122, the deformable part 122 can partially extend out of the mounting channel 111 from the limiting section 111b, which is beneficial to the judgment of the installation personnel or the sensor to identify whether the deformable part 122 and the mounting channel 111 are assembled in place.

[0045] In the embodiment, the first shell 11 is further provided with a redundant space 112 located at one end of the limiting section 111b away from the fixed section 111a, for accommodating one end of the deformable part 122 after being clamped.

[0046] Specifically, compared with extending the deformable part 122 out of the first shell 11, arranging a redundant space 112 in the first shell 11 to accommodate the part of the deformable part 122 extending out of the mounting channel 111 is more beneficial to the storage and management of the deformable part 122, avoiding the risk of deterioration or damage caused by exposure to the external environment. Moreover, the redundant space 112 can also isolate the mounting channel 111 from the external environment, avoiding the entry of impurities to affect the assembly effect and service life.

[0047] In the embodiment, the length H2 of the fixed section 111a is preferably greater than or equal to 20% of the height H1 of the first shell 11.

[0048] Specifically, the fixed section 111a is arranged along the height direction of the first shell 11 and mainly has the effect of extruding and fixing the deformable part 122. The deformable part 122 can only reach a certain depth of the first shell 11 to ensure the stable connection of the first shell 11 and the second shell 12. Of course, under the premise that the fixed section 111a can stably clamp the deformable part 122, the length values of H1 and H2 can be any reasonable relationship, for example, H2 can be less than 20% of H1.

[0049] In the embodiment, the first shell 11 includes an outer layer 113 and an abutting layer 114 which are sleeved from outside to inside. The abutting layer 114 has a limiting distance A from the inner bottom of the outer layer 113, and the abutting layer 114 is used to connect the top of the second shell 12. The limiting distance A is used to wrap the outer side of the second shell 12 with the outer layer 113.

[0050] Specifically, when the deformable part 122 and the mounting channel 111 are assembled, the abutting layer 114 abuts against the top of the second shell 12. At this time, the second shell 12 can no longer enter due to the limitation of the abutting layer 114, which can give an installation success signal to the installer or installation equipment. At the same time, the outer layer 113 wraps the outer side of the top of the second shell 12, which ensures the airtightness and stability of the connection between the abutting layer 114 and the top of the second shell 12. In addition, the abutting layer 114 also increases the thickness of the first shell 11, which has the effect of strengthening the structure of the first shell 11.

[0051] Further, the deformable part 122 protrudes from the shell main body 121, so the part abutted by the abutting layer 114 is the top of the shell main body 121, and the part wrapped by the outer layer 113 is also the shell main body 121.

[0052] In the embodiment, the abutting layer 114 includes a plurality of abutting sections 1141, and the plurality of abutting sections 1141 are arranged at intervals along the circumferential direction of the outer layer 113. The fixed section 111a is formed between two adjacent abutting sections 1141.

[0053] Specifically, the abutting layer 114 is preferably discontinuous inside the outer layer 113, which can reduce the overlap of materials under the premise of ensuring the strength of the first shell 11, so as to reduce the weight of the first shell 11. The fixed section 111a is ingeniously formed between the two abutting sections 1141, which can avoid the punching process on the first shell 11 and is conducive to the production efficiency and cost control of the first shell 11.

[0054] In the embodiment, the number of the deformable portions 122 is multiple, and the multiple deformable portions 122 are uniformly arranged along the circumference of the shell body 121, and the number and position of the mounting channels 111 are arranged corresponding to the deformable portions 122.

[0055] Specifically, the multiple deformable portions 122 are uniformly arranged along the circumference of the shell body 121, and the force of fixing the shell body 121 can be uniformly dispersed. The number of the deformable portions 122 is preferably 4, the shapes of the shell body 121 and the first shell 11 are selected as a square structure with chamfered corners according to the convention, the deformable portions 122 extend outward from each side of the right-angle edge of the shell body 121, and the mounting channels 111 are correspondingly arranged on each side of the right-angle edge of the first shell 11, and meanwhile, the abutting sections 1141 are arranged on the corners of the outer layer 113 and extend to each side of the right-angle edge, which can increase the stress bearing capacity of the corners and further strengthen the strength of the first shell 11.

[0056] The lens carrier 100 provided by the utility model, by setting the mounting channels 111 on the first shell 11 and the deformable portions 122 on the second shell 12, when assembling the first shell 11 and the second shell 12, the deformable portions 122 are inserted into the mounting channels 111, the mounting channels 111 can extrude the deformable portions 122, so that the deformable portions 122 are elastically deformed, thereby fixing the first shell 11 and the second shell 12. Such an assembling mode only needs to align the entrances of the deformable portions 122 and the mounting channels 111 and then insert, the process is very simple, the assembly is rapid, the efficiency is high, and the cost control is beneficial. And the cooperation between the deformable portions 122 and the first shell 11 is tightly abutted against the inner wall of the mounting channels 111 due to the outward expansion force of the deformable portions 122, so that the connection between the deformable portions 122 and the inside of the first shell 11 is more firm, and the fullness state of the deformable portions 122 in the mounting channels 111 makes the connection more compact.

Imaging chip is electrically connected with PCBA board 300, for receiving optical signal of lens module and carrying out imaging processing. Wherein, PCBA board refers to printed circuit board assembly, that is, the processing process of various electronic devices assembled on PCB circuit board, can also refer to the assembled circuit board. That is, PCB empty board is processed through SMT (surface mount technology) patch, and the entire production processing process is processed through DIP (dual in-line package), and is referred to as PCBA board.

[0059] Specifically, the control of the camera is realized by PCBA board 300, including starting, adjusting camera parameters, etc., the imaging chip converts the analog signal captured by the camera into a digital signal, and carries out necessary signal processing, such as noise reduction, enhancement, etc., and transmits the processed image data to other processing units or storage devices.
