[0031] Reference Figures 1 to 5The packaging structure of the lens module 200 in the embodiment of the application comprises a bearing body 100, the front surface of the bearing body 100 is arranged with a plurality of storage grooves for positioning the lens module 200, the storage grooves are recessed towards the back surface of the bearing body 100 to form a certain reinforcing structure, and the outlets of the storage grooves are flush with the front surface of the bearing body 100. The storage grooves can position and limit the horizontal displacement of the lens module 200 on one hand, and on the other hand, the recessed structure towards the back surface of the bearing body 100 can reinforce the rigidity of the bearing body 100, avoiding the case that the bearing body 100 is deformed greatly after all the storage grooves are filled with the lens module 200. All the side edges of the bearing body 100 extend towards the back surface of the bearing body 100 to form a supporting structure for supporting the bearing body 100, and a stacking structure is arranged at the joint between the bearing part 150 and the front surface of the bearing body 100 to enable two bearing bodies 100 to be stacked with each other. The arrangement of the bearing part 150 reinforces the rigidity of the edges of the bearing body 100, and facilitates the placement of a single bearing body 100. The arrangement of the stacking structure also reinforces the rigidity of the bearing part 150. In addition, the stacking structure limits the relative movement between two bearing bodies 100. More importantly, after two bearing bodies 100 are stacked vertically, the storage grooves of the lower bearing body 100 and the back surface of the upper bearing body 100 form a cavity for limiting the movement of the lens module 200, thereby limiting the horizontal and vertical displacement of the lens module 200. Through the optimization of the structure of the bearing body 100, the stacking is facilitated, and the lens module 200 is fully constrained in space, ensuring that the lens module 200 is fixed stably and does not collide with the bearing body 100.

[0032] As shown in Figures 1 to 4 The bearing body 100 is a rectangular base plastic plate, and after the bearing part 150 is arranged, the back surface of the bearing body 100 has a certain space structure in the form of a shell. The bearing body 100 has adjacent first and second sides, the opposite side of the first side is the third side, and the opposite side of the second side is the fourth side. The stacking structure of the first side is symmetrical to the stacking structure of the third side, and the stacking structure of the second side is symmetrical to the stacking structure of the fourth side, so that the two bearing bodies 100 can be stacked in the forward direction or in the reverse direction without limitation when the storage grooves are not placed with the lens module 200, improving the convenience of stacking.

[0033] As shown in Figure 6As shown, the included angle between the bearing part 150 and the front face of the bearing body 100 is between 90° and 100°, and specifically, the included angle between the bearing part 150 and the front face of the bearing body 100 in the embodiment is preferably 95°, so that after the two bearing bodies 100 are stacked, the space surrounded by the bearing part 150 of the upper bearing body 100 wraps the bearing part 150 of the lower bearing body 100, to form a better dustproof sealing structure. Further, the front face of the bearing body 100 is also provided with a slot 140 for placing a desiccant, and after the two bearing bodies 100 are stacked, the desiccant placed in the slot 140 can keep the formed cavity dry, to ensure that the storage quality of the lens module 200 is guaranteed, and dust and moisture are prevented.

[0034] In some embodiments, as shown in Figure 6 As shown, the end of the bearing part 150 away from the bearing body 100 is provided with a flange 151 parallel to the bearing body 100. The provision of the flange 151 can on the one hand improve the stress area when a bearing body 100 is placed alone, and is beneficial to prevent deformation caused by uneven local stress.

[0035] In other embodiments, as shown in Figures 1 to 5 As shown, the bearing part 150 is also provided with a plurality of inwardly recessed first reinforcing parts 152, the two ends of the first reinforcing part 152 respectively adjoin the flange 151 and the front face of the bearing body 100, and the provision of the first reinforcing part 152 greatly improves the structural rigidity of the bearing part 150.

[0036] In other embodiments, as shown in Figure 6 As shown, the stacking structure includes a first stacking part 160 and a second stacking part 170, the first stacking part 160 is adjacent to the second stacking part 170, and the first stacking part 160 and the second stacking part 170 are both recessed grooves towards the back face of the bearing body 100, and the bottom of the groove forming the second stacking part 170 is flat with the flange 151, so that the back face of the bearing body 100 forms a first bearing part 171, and the wall surface caused by the groove formed by the first stacking part 160 and the second stacking part 170 further improves the structural rigidity of the bearing part 150, wherein, as shown in Figure 8 As shown, after the two bearing bodies 100 are stacked, the first bearing part 171 of one bearing body 100 is clamped in the first stacking part 160 of the other bearing body 100, and it should be noted that the number of stacking structures can be increased or decreased according to the length of the side, and no specific number is limited here.

[0037] Further, as shown in Figure 6As shown, the included angle between the groove wall of the missing groove and the front face of the bearing body 100 is between 90° and 100°, so as to facilitate the clamping of the first bearing part 171 and the first stacking part 160 to achieve limiting, wherein the included angle between the groove wall of the missing groove and the front face of the bearing body 100 is preferably 95°, and the depth of the missing groove forming the first stacking part 160 is one-fifth of the length between the two ends of the bearing part 150. Too deep is not conducive to the arrangement of the lens module 200, and too shallow can easily lead to a decrease in the dustproof sealing performance and stacking stability between the two bearing bodies 100 after stacking.

[0038] In some other embodiments, as shown in Figures 1 to 3 As shown, the storage groove includes a first profiling groove 110 and a second profiling groove 120, both of which are recessed towards the back face of the bearing body 100, so that the back face of the bearing body 100 is correspondingly formed with a first limiting part and a second limiting part at positions corresponding to the first profiling groove 110 and the second profiling groove 120, and a first supporting part 130 is raised between the first profiling groove 110 and the second profiling groove 120, as shown in Figure 8 and Figure 9 As shown, the first supporting part 130 supports the middle part of the lens module 200 close to the front group end 202, the first profiling groove 110 can accommodate the front group end 202 of the lens module 200, and the second profiling groove 120 is used to position and support the fixed end of the lens module 200, wherein, as shown in Figure 8 and Figure 9 As shown, after the two bearing bodies 100 are stacked one on top of the other, the first limiting part is located above the second profiling groove 120, and the second limiting part is located above the first profiling groove 110. As shown in Figure 10 and Figure 11 As shown, it should be noted that after the two bearing bodies 100 are stacked on each other, the lens modules 200 on the two bearing bodies 100 are placed in opposite directions, effectively utilizing the first limiting part and the second limiting part formed on the back face of the bearing body 100, and through the cooperation of the first limiting part and the second limiting part with the first profiling groove 110, the second profiling groove 120 and the first supporting part 130, the lens module 200 is completely positioned and limited, the horizontal and vertical displacement of the lens module 200 is limited, and collision of the lens module 200 during transportation is avoided. The above structure design facilitates the subsequent mold modification of the bearing body 100.

[0039] Further, the bottom of the groove forming the second profiling groove 120 is provided with a first protrusion 121, a second protrusion 122 and a third protrusion 123 distributed in a triangular position relationship, which effectively support the fixed end of the lens module 200. The second protrusion 122 is provided with a step 124 close to the first supporting part 130 to limit the flange 201 of the fixed end of the lens module 200. Figure 7 As shown, the bottom of the first profiling groove 110 is raised upward to form a first limiting groove 112 in the first limiting part. The first limiting groove 112 is long strip-shaped, and the width of the first limiting groove 112 is 1-2 mm larger than the thickness of the flange 201. After the two pieces of the bearing body 100 are stacked, the flange 201 of the fixed end of the lens module 200 can be clamped into the first limiting groove 112. The protrusion, the step 124 and the first limiting groove 112 completely constrain the movement of the lens module 200 in the horizontal direction, and can effectively improve the shaking of the lens module 200 placed in the storage groove.

[0040] Further, the bottom of the second profiling groove 120 is recessed to form a fourth protrusion 127 in the second limiting part. The two side walls of the second profiling groove 120 are symmetrically provided with a second limiting groove 125 at the position adjacent to the front face of the bearing body 100. After the two pieces of the bearing body 100 are stacked, the fourth protrusion 127 is opposite to the first supporting part 130. The fourth protrusion 127 cooperates with the first supporting part 130 to limit the movement of the front group end 202 of the lens module 200 in the vertical direction, so as to avoid the risk of the lens module 200 being too long and being warped after the two pieces of the bearing body 100 are stacked. This can maximize the control of the contact between the lens module 200 and the bearing body 100, and play a role in stabilizing the lens module 200. The two sides of the first limiting part are clamped in the two second limiting grooves 125, respectively. The first limiting part is supported by the second limiting groove 125, that is, the middle position of the bearing body 100 is supported, so as to avoid the risk of the middle part being deformed after the two pieces of the bearing body 100 are stacked. This is beneficial to protect the lens module 200.

[0041] In some other embodiments, as Figures 1 to 3A first through groove 102 or a second through groove 103 is formed between two adjacent storage slots, so that the front of the support body 100 is formed with a second reinforcing part 101 in the shape of "I" and the two adjacent storage slots are connected. It should be noted that the bottom of the first through groove 102 or the second through groove 103 is higher than the bottom of the storage slot, so that the storage slot has sufficient groove wall to limit and protect the lens module 200. In addition, the formed first through groove 102 or the second through groove 103 strengthens the overall structural rigidity of the support body 100. Specifically, the second reinforcing part 101 strengthens the overall structural strength of the support body 100, increases the internal load capacity of the support body 100, and plays a role in preventing internal collapse. One important significance is that it distributes the load of the support body 100 located on the upper side when stacked, so that the center part, which is most prone to collapse, is greatly improved. The distributed force is evenly distributed to various parts of the blister box along the second reinforcing part 101 after demolding, further improving the overall structural performance.

[0042] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
