[0027] The following description is provided to enable those skilled in the art to implement the present invention. Other obvious replacements, modifications and variations may occur to those skilled in the art. Therefore, the scope of protection of the present invention should not be limited to the exemplary embodiments described herein.

[0028] Those skilled in the art should understand that, unless otherwise specified herein, the terms "one" and "an" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple.

[0029] Those skilled in the art should understand that, unless otherwise specified herein, the directions or positions referred to by the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the directions or positions shown in the drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the devices or elements involved must have a specific direction or position. Therefore, the above terms should not be understood as limiting the present invention.

[0030] Referring to the accompanying drawings of the present invention Figures 1 to 6, a driving device of a camera module according to an embodiment of the present invention, and a bracket and a method for manufacturing the bracket are explained. The driving device 100 includes a bracket 1, a carrier 2 accommodated in the bracket 1, and a driving assembly 3, wherein the guide rod 11 of the bracket 1 is arranged on the inner side of the bracket 1 in a manner facing the carrier 2, the carrier 2 is movably supported on the guide rod 11, and the driving assembly 3 is configured to drive the carrier 2 to move relative to the bracket 1 along the extension direction of the guide rod 11, and further to realize the focus or zoom function of the camera module. In the relative movement relationship between the carrier 2 and the bracket 1, the bracket 1 can be regarded as a stator, and the carrier 2 can be regarded as a mover. The driving assembly 3 drives the carrier 2 to move relative to the bracket 1, and then the carrier 2 is used to drive the entire optical lens of the camera module or a part of the optical lens to move along the optical axis of the optical lens to realize the focus or zoom function of the camera module.

[0031] It can be understood that the driving mode of the driving component 3 includes but is not limited to magnetic drive, piezoelectric drive or motor drive. The driving mode of the driving component 3 and its specific structural structure should not be regarded as limiting the protection scope of the present invention. Any driving component that can drive the carrier 2 to move relative to the bracket 1 along the extension direction of the guide rod 11 belongs to the optional implementation of the present invention and should be covered by the protection scope of the present invention. In order to facilitate the complete illustration of the technical solution of the present invention, only the magnetic drive mode is illustrated in the drawings of the present invention.

[0032] Referring to the accompanying drawings of the present invention Figure 2 and Figure 4 In an optional embodiment in which the driving component 3 is implemented as a magnetic drive, the driving component 3 includes a first coil 311 and a first magnet 312, wherein one of the first coil 311 and the first magnet 312 is disposed on the bracket 1, and the other is disposed on the carrier 2, and the first coil 311 is disposed opposite to the first magnet 312. The driving component 3 also includes a first magnetic sheet 313, wherein the first magnetic sheet 313 is disposed on a side of the first coil 311 away from the first magnet 312, so that the carrier 2 is adsorbed on a side of the bracket 1 where the guide rod 11 is disposed through the magnetic attraction between the first magnetic sheet 313 and the first magnet 312, and further drives the carrier 2 to move relative to the bracket 1 along the extension direction of the guide rod 11.

[0033] Referring to the accompanying drawings of the present invention FIG. 5A to FIG. 5G, the manufacturing process of the bracket 1 is shown in sequence. First, a preform 120 is manufactured, wherein the preform 120 can be manufactured by stamping or cutting a metal plate, or by die casting, forging or powder metallurgy. Figure 5A As shown, the preform 120 includes at least one supporting sheet 121, a supporting portion 122 located at the periphery of the preform 120, and a connecting portion 123 connected between the supporting sheet 121 and the supporting portion 122, wherein the supporting portion 122 is annular and rectangular, and the supporting portion 122 is arranged on the outside of the supporting sheet 121 and the connecting portion 123 in a manner of surrounding the supporting sheet 121 and the connecting portion 123, and the connecting portion 123 includes a plurality of connecting branches 1230, and the supporting sheet 121 is connected to the supporting portion 122 through the connecting branches 1230, so that the supporting sheet 121 is maintained in the space surrounded by the supporting portion 122. After subsequent steps, the supporting sheet 121 will eventually be embedded in the bracket 1, and is used to fix the corresponding guide rod 11 during the manufacturing process of the bracket 1, and ensure the setting accuracy of the guide rod 11, which is conducive to improving the setting accuracy of the guide rod 11.

[0034] It can be understood that the number of the supporting plates 121 may be only one, or may be two, three or more. The number of the supporting plates 121 is consistent with the number of the guide rods 11 of the bracket 1, and the supporting plates 121 and the guide rods 11 correspond to each other. The more the number of the guide rods 11 (i.e., the number of the supporting plates 121), the more reliable the guiding effect on the carrier 2, and the greater the stability of the carrier 2 during movement. However, the friction force to which the carrier 2 is subjected during movement will increase with the increase in the number of the guide rods 11. Preferably, the number of the guide rods 11 and the number of the supporting plates 121 are both two. In the drawings of the present invention, only the implementation mode of two guide rods 11 and two supporting plates 121 is illustrated, as shown in FIG. Figure 1 and Figure 2 As shown, the guide rod 11 includes a first guide rod 111 and a second guide rod 112. Figure 5A As shown, the supporting piece 121 includes a first supporting piece 1211 and a second supporting piece 1212 , wherein the first guide rod 111 corresponds to the first supporting piece 1211 , and the second guide rod 112 corresponds to the second supporting piece 1212 .

[0035] Continue to refer to the accompanying drawings of the present invention Figure 5A, the first supporting sheet 1211 and the second supporting sheet 1212 are arranged on the same side of the preform 120, and are located on the same side of the preform 120 as the first side 1221 of the support portion 122, wherein an air gap is formed between the supporting sheet 121 and the first side 1221 of the support portion 122, so that the supporting sheet 121 can be bent in subsequent steps, wherein an air gap is formed between the first supporting sheet 1211 and the first side 1221, and an air gap is also formed between the second supporting sheet 1212 and the first side 1221. Preferably, the first supporting sheet 1211 and the second supporting sheet 1212 are connected to each other through the first branch 1231 of the connecting branch 1230, so as to enhance the relative position accuracy between the first supporting sheet 1211 and the second supporting sheet 1212. In other words, by relying on the first branch 1231, it is possible to enhance the structural strength of the preform 120 while ensuring the spacing between the first supporting plate 1211 and the second supporting plate 1212, thereby weakening the influence of subsequent steps on the relative position accuracy between the first supporting plate 1211 and the second supporting plate 1212.

[0036] Continue to refer to the accompanying drawings of the present invention Figure 5A In addition to the supporting sheet 121, the bracket 1 may also be embedded with certain metal parts for realizing specific functions. Therefore, at least one functional part 124 may be simultaneously arranged in the preform 120, so that the functional part 124 eventually forms a metal part embedded in the bracket 1 for realizing specific functions. For example, it can be used as a structural reinforcement for the groove of the bracket 1, specifically as a structural reinforcement for the ball groove of the bracket 1 to enhance the structural strength of the ball groove. It can also be used as a structural reinforcement for other parts of the bracket 1, and can also be used as a conductive part. In other words, arranging the functional part 124 and the supporting sheet 121 in the same preform 120 is conducive to simplifying the manufacturing process of the bracket 1. The number and setting position of the functional part 124 can be adaptively selected according to the specific structural configuration of the bracket 1 to match the bracket 1. In the drawings of the present invention, only four implementation modes of the functional parts 124 are illustrated, as shown in FIG. Figure 5A As shown, the functional portion 124 includes a first functional portion 1241 , a second functional portion 1242 , a third functional portion 1243 and a fourth functional portion 1244 .

Accordingly, in some embodiments of the present invention, at least one supporting sheet 121 is connected to the supporting portion 122 via the connecting branch 1230, so as to keep the supporting sheet 121 on the inner side of the supporting portion 122.

[0039] exist Figure 5A In the illustrated embodiment, the first supporting sheet 1211 is connected to the first functional portion 1241 via the third branch 1233 of the connecting branch 1230. Accordingly, in some embodiments of the present invention, at least one supporting sheet 121 is connected to at least one functional portion 124 via the connecting branch 1230, which is not only conducive to enhancing the structural strength of the preform 120, but also conducive to ensuring the position accuracy of the supporting sheet 121, and weakening the influence of subsequent steps on the position accuracy of the supporting sheet 121.

[0040] exist Figure 5A In the illustrated embodiment, the second supporting sheet 1212 is directly connected to the second functional portion 1242, that is, the two are no longer connected to each other through the connecting branch 1230. Accordingly, in some embodiments of the present invention, at least one supporting sheet 121 is directly connected to at least one functional portion 124, and is no longer connected to each other through the connecting branch 1230, so that the distribution of the supporting sheet 121 and the functional portion 124 is more concentrated, which can further ensure the position accuracy of the supporting sheet 121 and reduce the influence of subsequent steps on the position accuracy of the supporting sheet 121.

[0041] exist Figure 5AIn the illustrated embodiment, the connecting branch 1230 includes four fourth branches 1234, and the four functional parts 124 are respectively connected to the support part 122 through the four fourth branches 1234, wherein the first functional part 1241 and the fourth functional part 1244 are connected to the fourth side 1224 of the support part 122 through the fourth branches 1234, and the second functional part 1242 and the third functional part 1243 are connected to the second side 1222 of the support part 122 through the fourth branches 1234. Optionally, in some embodiments of the present invention, the third functional part 1243 and / or the fourth functional part 1244 may be connected to the third side 1223 of the support part 122 through the fourth branches 1234. Accordingly, in some embodiments of the present invention, at least one of the functional parts 124 is connected to the support part 122 via the connecting branch 1230 , so as to keep the functional part 124 on the inner side of the support part 122 .

[0042] It is worth mentioning that the first side portion 1221, the second side portion 1222, the third side portion 1223 and the fourth side portion 1224 are integrally formed to enclose the support portion 122, wherein the first side portion 1221 is opposite to the third side portion 1223 and extends between the second side portion 1222 and the fourth side portion 1224, and the second side portion 1222 is opposite to the fourth side portion 1224 and extends between the first side portion 1221 and the third side portion 1223.

[0043] exist Figure 5A In the illustrated embodiment, the connecting branch 1230 includes four fifth branches 1235 and one sixth branch 1236, and the connecting portion 123 includes a gathering portion 1237 located in the middle of the preform 120, wherein the four functional portions 124 are respectively connected to the gathering portion 1237 through the four fifth branches 1235, and the first supporting plate 1211 is connected to the gathering portion 1237 through the sixth branch 1236. Accordingly, in some embodiments of the present invention, the connecting portion 123 includes a gathering portion 1237 located in the middle of the preform 120, wherein at least one of the supporting pieces 121 is connected to the gathering portion 1237 via the connecting branch 1230, and at least one of the functional portions 124 is connected to the gathering portion 1237 via the connecting branch 1230, thereby further enhancing the structural strength of the preform 120, further ensuring the position accuracy of the supporting piece 121, and further weakening the influence of subsequent steps on the position accuracy of the supporting piece 121.

[0044] exist Figure 5AIn the illustrated embodiment, the four functional parts 124 are respectively located at the four corners of the preform 120, so that the distribution of the four functional parts 124 is more uniform, which is beneficial to enhancing the structural strength of the preform 120, so as to further ensure the position accuracy of the supporting piece 121, and weaken the influence of subsequent steps on the position accuracy of the supporting piece 121.

[0045] Continue to refer to the accompanying drawings of the present invention Figure 5A , the supporting sheet 121 includes a base 1213, a bending portion 1214 and a fixing portion 1215, wherein the bending portion 1214 is disposed between the base 1213 and the fixing portion 1215, the bending portion 1214 connects the base 1213 and the fixing portion 1215, and a width W1 of the bending portion 1214 is smaller than a width W2 of the fixing portion 1215, so that the bending portion 1214 is easy to bend. Preferably, the width W1 of the bending portion 1214 is also smaller than a width W3 of the base 1213, thereby forming a gap between the base 1213 and the fixing portion 1215, further facilitating the bending portion 1214 to bend. The width W2 of the fixing portion 1215 may be greater than the width W3 of the base 1213, such as Figure 5A The width W2 of the fixing portion 1215 may also be smaller than the width W3 of the base portion 1213, as shown in FIG. Figure 5A The second supporting sheet 1212 is shown. Optionally, the width W2 of the fixing portion 1215 may also be equal to the width W3 of the base portion 1213.

[0046] It is worth mentioning that in Figure 5A In the illustrated embodiment, the bent portion 1214 of the first supporting piece 1211 and the bent portion 1214 of the second supporting piece 1212 extend in the same straight line direction to ensure that the first guide rod 111 and the second guide rod 112 of the formed bracket 1 can be located in the same plane, thereby ensuring the setting accuracy of the guide rod 11.

[0047] It is also worth mentioning that in Figure 5A In the illustrated embodiment, the connecting branch 1230 connected to the supporting sheet 121 is connected to the base 1213 of the supporting sheet 121. In other words, the supporting sheet 121 is connected to the connecting branch 1230 only through the base 1213, and the bending portion 1214 and the fixing portion 1215 are not connected to the connecting branch 1230, so that the bending portion 1214 and the fixing portion 1215 can be bent in subsequent steps.

[0048] Referring to the accompanying drawings of the present invention Figure 5B ,exist Figure 5AAfter the steps shown, the fixing portion 1215 of the supporting sheet 121 of the preform 120 is bent, such as by processing the preform 120 through a stamping process, so that the fixing portion 1215 of the supporting sheet 121 is bent. Specifically, at least one of the two adjacent sides of the fixing portion 1215 adjacent to the bending portion 1214 is bent upward, so that after the fixing portion 1215 is bent, a bearing portion 1216 and at least one side limiting portion 1217 are formed, wherein the plane where the side limiting portion 1217 is located intersects with the plane where the bearing portion 1216 is located, that is, the side limiting portion 1217 and the bearing portion 1216 are not located in the same plane. In other words, an angle α is formed between the side limiting portion 1217 and the bearing portion 1216, and preferably, the angle α is greater than or equal to 60° and less than or equal to 120°. More preferably, the angle α is equal to 90°. By utilizing the limiting or positioning function of the side limiting portion 1217, the circumferential side position of the guide rod 11 can be limited or positioned, so that in subsequent steps, the guide rod 11 can be placed on the fixing portion 1215 of the supporting plate 121 and the setting accuracy of the guide rod 11 can be ensured.

[0049] exist Figure 5B In the embodiment shown, preferably, the two adjacent sides of the fixing portion 1215 adjacent to the bending portion 1214 are bent upwards, so that after the fixing portion 1215 is bent, two side limiting portions 1217 are formed, so that the fixing portion 1215 is bent to form a groove-like structure. By using the fixing portion 1215 forming a groove-like structure and the limiting or positioning function of the two side limiting portions 1217 on both sides, the setting accuracy of the guide rod 11 can be further ensured.

[0050] Continue to refer to the accompanying drawings of the present invention Figure 5B When the preform 120 is processed by a stamping process to bend the fixing portion 1215 of the supporting piece 121, the setting height of at least one of the supporting pieces 121 can be adjusted at the same time. Specifically, the connecting branch 1230 connected to the corresponding supporting piece 121 is bent to change the setting height of the base 1213 of the supporting piece 121, so as to meet the different setting height requirements of the guide rod 11. It can be understood that the setting height of each supporting piece 121 can be adjusted by bending the connecting branch 1230 connected thereto. Figure 5BIn the illustrated embodiment, only the setting height of the first supporting sheet 1211 is adjusted for illustration, wherein the first branch 1231, the third branch 1233 and the sixth branch 1236 connected to the first supporting sheet 1211 are all bent, so that the base 1213 of the first supporting sheet 1211 sinks relative to the plane where the support portion 122 is located, thereby achieving the adjustment of the setting height of the first supporting sheet 1211. Accordingly, in some embodiments of the present invention, when the setting height of the second supporting sheet 1212 needs to be adjusted, since the second functional portion 1242 is directly connected to the base 1213 of the second supporting sheet 1212, it is necessary not only to bend the first branch 1231 connected to the second supporting sheet 1212, but also to bend the fourth branch 1234 and the fifth branch 1235 connected to the second functional portion 1242. It is worth mentioning that the setting height of the supporting plate 121 of the present invention refers to the height of the base 1213 of the supporting plate 121 with the plane where the support portion 122 is located as the horizontal plane (ie, the reference plane, reference plane or coordinate plane).

[0051] Referring to the accompanying drawings of the present invention Figure 5C ,exist Figure 5BAfter the steps shown, the guide rod 11 is placed on the corresponding fixing portion 1215 of the supporting sheet 121, and the circumferential position of the guide rod 11 is limited or positioned by the side limiting portion 1217 of the fixing portion 1215. Specifically, the first guide rod 111 and the second guide rod 112 are placed on the fixing portion 1215 of the first supporting sheet 1211 and the fixing portion 1215 of the second supporting sheet 1212, respectively. When the two included angles α formed between the two side limiting portions 1217 of the supporting sheet 121 and the bearing portion 1216 are both 90°, in some embodiments of the present invention, the size of the side limiting portion 1217 in the direction away from the bearing portion 1216 is greater than or equal to the radius of the corresponding guide rod 11, and the distance between the two side limiting portions 1217 of the supporting sheet 121 is slightly greater than the diameter of the corresponding guide rod 11, so that the guide rod 11 can be placed in the fixing portion 1215 of the corresponding supporting sheet 121 with good accuracy. Preferably, the difference between the distance between the two side limiting portions 1217 of the supporting sheet 121 and the diameter of the corresponding guide rod 11 is between 10μm and 70μm, so as to simultaneously meet the requirements of the manufacturing accuracy of the preform 120 and the setting accuracy of the guide rod 11. In other embodiments of the present invention, the size of the side limiting portion 1217 in the direction away from the bearing portion 1216 may also be smaller than the radius of the corresponding guide rod 11. At this time, the distance between the two side limiting portions 1217 of the supporting plate 121 may be slightly smaller than the diameter of the corresponding guide rod 11.

[0052] Continue to refer to the accompanying drawings of the present invention Figure 5C After the guide rod 11 is placed on the fixing portion 1215 of the corresponding supporting sheet 121, the guide rod 11 is fixed to the fixing portion 1215 of the corresponding supporting sheet 121, wherein the guide rod 11 is fixed to the fixing portion 1215 of the corresponding supporting sheet 121 through the side of the guide rod 11. The fixing method between the guide rod 11 and the fixing portion 1215 of the corresponding supporting sheet 121 includes but is not limited to glue fixing, welding, laser welding or heat welding, etc.

[0053] When fixing by glue, glue (such as thermosetting glue) can be applied to the fixing portion 1215 first, and then the corresponding guide rod 11 is placed on the fixing portion 1215, and then the glue is cured by heating, so that the guide rod 11 is fixed to the fixing portion 1215 of the corresponding supporting sheet 121. Of course, the guide rod 11 can also be placed on the fixing portion 1215 of the corresponding supporting sheet 121 first, and then glue is filled between the guide rod 11 and the fixing portion 1215, and then the glue is cured. In other words, when fixing by glue, the glue is arranged between the guide rod 11 and the fixing portion 1215, and after the glue is cured, the glue contacts and fixes the guide rod 11, the side limiting portion 1217 of the fixing portion 1215, and the bearing portion 1216 of the fixing portion 1215. It can be understood that the glue fixation does not impose any limitation on the material of the guide rod 11, and the guide rod 11 can be made of materials such as plastic, metal, glass and / or ceramic.

[0054] When fixed by welding, the guide rod 11 is first placed on the fixing portion 1215 of the corresponding supporting sheet 121, and then the guide rod 11 is welded to the fixing portion 1215 by solder or other welding medium. It can be understood that when fixed by welding, the guide rod 11 is implemented as a metal guide rod, which is made of metal material.

[0055] When fixing by laser welding, the guide rod 11 is first placed on the fixing portion 1215 of the corresponding supporting sheet 121, and then the guide rod 11 and the fixing portion 1215 are irradiated with laser at the contact position of the guide rod 11 and the fixing portion 1215 to weld the guide rod 11 and the fixing portion 1215. It can be understood that when fixing by laser welding, the guide rod 11 is implemented as a metal guide rod made of metal material.

[0056] When fixing by heating and welding, the guide rod 11 is first placed on the fixing portion 1215 of the corresponding supporting sheet 121, and then the side of the bearing portion 1216 of the fixing portion 1215 away from the guide rod 11 is heated (for example, heated by friction), so that the guide rod 11 is welded to the bearing portion 1216 of the fixing portion 1215. It can be understood that when fixing by heating and welding, the guide rod 11 is implemented as a metal guide rod, which is made of metal material. It can also be understood that since the heating position is the side of the bearing portion 1216 away from the guide rod 11, the outer shape structure of the guide rod 11 facing away from the bearing portion 1216 will not be affected by the welding process, thereby not affecting the guiding function of the guide rod.

[0057] Continue to refer to the accompanying drawings of the present invention Figure 5CBefore, during, and after the guide rod 11 is fixed to the fixing portion 1215 of the corresponding supporting sheet 121, the end of the base 1213 of the guide rod 11 close to the supporting sheet 121 is misaligned with the base 1213, so that the fixing portion 1215 and the bending portion 1214 can be bent in subsequent steps. In other words, when viewed from a direction perpendicular to the base 1213, the guide rod 11 does not overlap with the base 1213, and the end of the guide rod 11 close to the base 1213 does not overlap with the base 1213. Therefore, when the guide rod 11 is placed and fixed on the fixing portion 1215 of the corresponding supporting plate 121, a jig can be used to limit or position the end of the guide rod 11 away from the base 1213 to improve the setting accuracy of the guide rod 11 and ensure that the end of the guide rod 11 close to the base 1213 is offset from the base 1213.

[0058] Continue to refer to the accompanying drawings of the present invention Figure 5C , the ratio of the length L1 of the bearing portion 1216 of the fixing portion 1215 to the length L2 of the corresponding guide rod 11 is greater than or equal to 0.4. Preferably, the ratio of the length L1 of the bearing portion 1216 to the length L2 of the corresponding guide rod 11 is greater than or equal to 0.5. For example, in one embodiment of the present invention, the ratio of the length L1 of the bearing portion 1216 to the length L2 of the corresponding guide rod 11 is about 0.53, wherein the length L1 of the bearing portion 1216 is 4 mm, and the length L2 of the corresponding guide rod 11 is 7.6 mm. It can be understood that if the ratio of the length L1 of the bearing portion 1216 to the length L2 of the corresponding guide rod 11 is too small, most of the guide rod 11 is not carried and supported by the bearing portion 1216, and when the guide rod 11 is not completely fixed to the fixing portion 1215 (especially in the embodiment of fixing with glue, when the glue is not completely cured, the bonding force is insufficient), there is a risk of the guide rod 11 falling off. In particular, when the ratio of the length L1 of the bearing portion 1216 to the length L2 of the corresponding guide rod 11 is less than 0.5, the center position of the guide rod 11 is suspended and is not carried and supported by the bearing portion 1216, and the risk of the guide rod 11 falling off is relatively large. Moreover, in some embodiments of the present invention, in order to simplify the structural construction of the fixing portion 1215, the side limit portion 1217 of the fixing portion 1215 has the same length as the bearing portion 1216. At this time, if the ratio of the length L1 of the bearing portion 1216 to the length L2 of the corresponding guide rod 11 is too small, the ratio of the length of the side limit portion 1217 to the length L2 of the corresponding guide rod 11 will also be too small, and the guide rod 11 may be at risk of tilting relative to the side limit portion 1217 in the bearing portion 1216.

[0059] Referring to the accompanying drawings of the present invention Figure 5D ,exist Figure 5C After the steps shown, the bent portion 1214 of the supporting sheet 121 is bent, so that the fixed portion 1215 of the supporting sheet 121 is turned up toward the side where the guide rod 11 is provided, and the bent portion 1214 is bent and deformed (such as being bent into an arc shape), so that the fixed portion 1215 and the guide rod 11 are vertically arranged relative to the base 1213. It can be understood that considering the manufacturing tolerance of the preform 120 and the bending tolerance during bending, the "vertical arrangement" refers to a substantially vertical arrangement, which may have a deviation of about 1°. Accordingly, when the guide rod 11 includes the first guide rod 111 and the second guide rod 112, the first guide rod 111 and the second guide rod 112 are arranged in parallel. It can be understood that considering the manufacturing tolerance of the preform 120 and the bending tolerance when bending, the manufacturing tolerance of the guide rod 11 and the fixing tolerance when fixing, the "parallel arrangement" refers to a roughly parallel arrangement, and there may also be a small angle deviation.

[0060] Continue to refer to the accompanying drawings of the present invention Figure 5D Since the setting height of the base 1213 of the first supporting piece 1211 is lower than the setting height of the base 1213 of the second supporting piece 1212, and the length of the first guide rod 111 is greater than the length of the second guide rod 112, the second guide rod 112 can correspond to the middle part of the first guide rod 111, so that the two guide rods 11 of different lengths can realize corresponding functions in the bracket 1.

[0061] Referring to the accompanying drawings of the present invention Figure 5E ,exist Figure 5D After the steps shown, the end of the guide rod 11 close to the base 1213 can be further fixed to the base 1213 so that the angle (approximately 90°) of the guide rod 11 relative to the base 1213 can be maintained, that is, the guide rod 11 is maintained in a state of being approximately vertically arranged relative to the base 1213 to avoid angle changes in subsequent steps, which is beneficial to further ensure the setting accuracy of the guide rod 11.

[0062] It should be understood that, no matter whether the bent portion 1214 of the supporting sheet 121 is bent before or after being bent, the guide rod 11 is parallel to the fixing portion 1215 of the supporting sheet 121 fixed to the guide rod 11. In other words, the guide rod 11 is fixed to the fixing portion 1215 of the corresponding supporting sheet 121 through its side surface, and the side surface of the guide rod 11 is fixed to the fixing portion 1215 of the corresponding supporting sheet 121.

[0063] Continue to refer to the accompanying drawings of the present invention Figure 5E In order to facilitate fixing the end of the guide rod 11 close to the base 1213 to the base 1213, the base 1213 is provided with an exposed portion 1218, so that the end of the guide rod 11 close to the base 1213 is exposed at the exposed portion 1218, so as to avoid the base 1213 completely covering the end of the guide rod 11 close to the base 1213. Furthermore, it is convenient to fix the end of the guide rod 11 close to the base 1213 to the base 1213 at the exposed portion 1218 of the base 1213 by glue fixing, welding, laser welding or heat welding. Further, considering that the base 1213 has the function of maintaining the setting height and angle of the guide rod 11, the base 1213 should cover the end of the guide rod 11 close to the base 1213 to a large extent, so as not to affect the function of the base 1213. Preferably, the base 1213 at least covers a half of the end of the guide rod 11 close to the base 1213 .

[0064] exist Figure 5E In the illustrated embodiment, two specific structures of the exposed portion 1218 of the base 1213 are specifically illustrated. In the first supporting sheet 1211, the exposed portion 1218 is implemented as a notch. It is understood that the exposed portion 1218 can be implemented as a notch of various shapes, such as a notch of a regular or irregular polygon such as a triangle, rectangle, rhombus, pentagon, a notch formed by a part of a circle, or even a notch of other irregular shapes. In the second supporting sheet 1212, the exposed portion 1218 is implemented as a through hole located in the middle of the base 1213 of the second supporting sheet 1212. It is understood that in some embodiments of the present invention, the exposed portion 1218 of the first supporting sheet 1211 is a through hole, and the exposed portion 1218 of the second supporting sheet 1212 is a notch; in some embodiments of the present invention, the exposed portions 1218 are both notches or both through holes. In other words, in some embodiments of the present invention, the exposed portion 1218 of at least one of the supporting sheets 121 is a notch; in some embodiments of the present invention, the exposed portion 1218 of at least one of the supporting sheets 121 is a through hole.

[0065] Referring to the accompanying drawings of the present invention Fig. 5F ,exist Figure 5D After the steps shown, or after Figure 5EAfter the steps shown, the preform 120 and the guide rod 11 are placed in an injection mold, and the main body 13 of the bracket 1 is formed by injection molding based on the preform 120 and the guide rod 11. The main body 13 of the bracket 1 covers at least a portion of the support sheet 121, and the main body 13 of the bracket 1 covers a portion of the guide rod 11, so that the support sheet 121 and the guide rod 11 are embedded in the main body 13 of the bracket 1. Specifically, in combination with the attached Figure 1 and attached Figure 2 The side of the bearing portion 1216 of the fixing portion 1215 of the guide rod 11 facing away from the supporting sheet 121 is exposed to the main body 13 of the bracket 1 and is not covered by the main body 13 of the bracket 1, so that the guide rod 11 can face the carrier 2 and be used to support the carrier 2, so that the carrier 2 can be driven to move relative to the bracket 1 along the extension direction of the guide rod 11.

[0066] It can be understood that when the main body 13 of the bracket 1 is formed by injection molding, the main body 13 of the bracket 1 further covers at least a portion of the functional part 124, so that the functional part 124, the supporting plate 121 and the guide rod 11 are jointly embedded in the main body 13 of the bracket 1, thereby helping to simplify the manufacturing process of the bracket 1, wherein the functional part 124 eventually forms a metal part embedded in the main body 13 of the bracket 1 for realizing a specific function.

[0067] It can also be understood that the main body 13 of the bracket 1 can be formed by one injection molding, that is, the main body 13 of the bracket 1 is formed by only one injection molding step. The main body 13 of the bracket 1 can also be formed by two injection moldings or multiple injection moldings. The number of injection moldings of the main body 13 of the bracket 1 is related to the complexity of its structure. When its structure is more complex, at least two injection molding steps can be performed successively.

[0068] It is understandable, although Fig. 5F The main body 13 of the bracket 1 shown includes four side walls, but this is only an illustration of the present invention. In some embodiments of the present invention, according to actual needs, the main body 13 of the bracket 1 may have only one, two or three side walls, and the remaining positions are open.

[0069] Continue to refer to the accompanying drawings of the present invention Fig. 5F , and combined with Figures 1 to 3, the degree to which the first guide rod 111 is exposed from the main body 13 of the bracket 1 is greater than the degree to which the second guide rod 112 is exposed from the main body 13 of the bracket 1, so that the first guide rod 111 can play a major guiding role, while the second guide rod 112 can play an auxiliary role. Figure 3 As shown, the carrier 2 is provided with a guide groove 21 and a support groove 22, wherein the guide groove 21 is arranged to face and contact the first guide rod 111, the guide groove 21 is a V-shaped groove or a trapezoidal groove, at least two groove walls of the guide groove 21 are in contact with the first guide rod 111, so that the first guide rod 111 can play a major guiding role, and the support groove 22 is arranged to face and contact the second guide rod 112, and only one groove wall of the support groove 22 is in contact with the second guide rod 112, so that the second guide rod 112 can play an auxiliary role. In order to reduce the friction resistance encountered by the carrier 2 during movement, the guide groove 21 and the support groove 22 are both provided with a protrusion 23, and the protrusion 23 protrudes in the direction of the corresponding guide rod 11, and is used to contact the corresponding guide rod 11. Preferably, the guide groove 21 is provided with at least two protrusions 23, and the upper end of the guide groove 21 and the lower end of the guide groove 21 are both provided with the protrusions 23, the support groove 22 is provided with only one protrusion 23, and the protrusion 23 of the support groove 22 is provided at the middle part of the support groove 22 or the lower end of the support groove 22, and the protrusion 23 cannot be provided at the upper end of the support groove 22, so that the protrusion 23 of the support groove 22 can match the second guide rod 112 with a relatively short length. It can be understood that, since the guide groove 21 is a V-shaped groove or a trapezoidal groove, each protrusion 23 of the guide groove 21 forms at least two contact surfaces (or contact areas) with the first guide rod 111.

[0070] Referring to the accompanying drawings of the present invention Figure 5G ,exist Fig. 5F After the steps shown, the support portion 122 and at least a portion of the connecting portion 123 of the preform 120 are removed to obtain the bracket 1. The first guide rod 111 and the second guide rod 112 are both embedded in the inner side of the bracket 1, and the first guide rod 111 and the second guide rod 112 are arranged substantially in parallel. Preferably, the first guide rod 111 and the second guide rod 112 are embedded in the same side wall of the main body 13 of the bracket 1.

[0071] Referring to the accompanying drawings of the present invention Figure 6After removing the support portion 122 and at least part of the connecting portion 123 of the preform 120, the remaining part of the preform 120 is retained in the bracket 1 to constitute the insert 12 of the bracket 1. In other words, the bracket 1 includes at least one guide rod 11, the insert 12 and the main body 13, wherein the guide rod 11 and the insert 12 are embedded together in the main body 13 of the bracket 1. Specifically, the insert 12 includes at least one supporting piece 121, and the guide rod 11 is fixed to the corresponding supporting piece 121, so that the supporting piece 121 can fix the corresponding guide rod 11 during the manufacturing process of the bracket 1 and ensure the setting accuracy of the guide rod 11, which is conducive to improving the setting accuracy of the guide rod 11. When the preform 120 is provided with the functional portion 124, the insert 12 also includes at least one functional portion 124, so that the functional portion 124, the supporting sheet 121 and the guide rod 11 are embedded together in the main body 13 of the bracket 1, thereby simplifying the manufacturing process of the bracket 1. It can be understood that in some embodiments of the present invention, the insert 12 also includes a part of the connecting branch 1230 of the connecting portion 123 of the preform 120, so that the part of the connecting branch 1230 retained in the main body 13 of the bracket 1 can be used to enhance the structural strength of the bracket 1. In addition, it is worth mentioning that since a part of the connecting branch 1230 is removed, a part of the remaining connecting branch 1230 is exposed to the main body 13 of the bracket 1 and is not completely covered by the main body 13 of the bracket 1.

[0072] It should be understood that, through the molding process of the bracket 1 with the guide rod 11, the vertically arranged guide rod is first fixed on a horizontal plane and then bent to make the guide rod vertical, which simplifies the guide rod fixing method and improves the setting accuracy of the guide rod.

[0073] Referring to the accompanying drawings of the present invention FIG. 7A to FIG. 7D , a partial manufacturing process of a bracket 1 according to another embodiment of the present invention is shown in sequence, which is similar to FIG. 5A to FIG. 5D The difference between the shown embodiment and its variant embodiment and optional embodiment is that the fixed portion 1215 of the supporting plate 121 is not only bent on at least one of the two adjacent sides adjacent to the bending portion 1214, but the fixed portion 1215 is also bent on the side away from the bending portion 1214 to form a top limiting portion 1219.

[0074] like Figure 7BAs shown, after the fixing portion 1215 is bent, the bearing portion 1216, the side limiting portion 1217 and the top limiting portion 1219 are formed, wherein the plane where the top limiting portion 1219 is located intersects with the plane where the bearing portion 1216 is located, that is, the top limiting portion 1219 and the bearing portion 1216 are not located in the same plane. Preferably, the angle formed between the top limiting portion 1219 and the bearing portion 1216 is 90°.

[0075] like Figure 7C As shown, when the guide rod 11 is placed and fixed on the corresponding fixing portion 1215 of the supporting sheet 121, the top limiting portion 1219 can be directly used to limit or position the end of the guide rod 11 away from the base 1213, so as to improve the setting accuracy of the guide rod 11 without using a jig to limit or position the end of the guide rod 11 away from the base 1213. It can be understood that when the jig is used for limiting or positioning, the setting tolerance of the guide rod 11 can only be ensured to be about 50μm, while when the top limiting portion 1219 is used for limiting or positioning, the setting tolerance of the guide rod 11 can be ensured to be about 30μm, which greatly improves the setting accuracy of the guide rod 11.

[0076] In order to facilitate the display and explanation of the width of the top limit portion 1219, Fig. 7A In the figure, when the fixing portion 1215 is not bent to form the top limiting portion 1219, the width of the top limiting portion 1219 is marked as W4. Preferably, the width W4 of the top limiting portion 1219 is smaller than the width W1 of the bending portion 1214, so that the fixing portion 1215 is bent to form the bearing portion 1216, the side limiting portion 1217 and the top limiting portion 1219.

[0077] like Figure 7B and Fig.7D As shown, preferably, the size of the top limit portion 1219 in the direction away from the bearing portion 1216 is smaller than the size of the side limit portion 1217 in the direction away from the bearing portion 1216. This is because the end surface of the end of the guide rod 11 away from the base 1213 can be implemented as a plane. Therefore, the top limit portion 1219 does not need to extend too long in the direction away from the bearing portion 1216, and can also play an effective limiting or positioning role.

[0078] exist Fig.7DAfter the steps shown, the preform 120 and the guide rod 11 also need to be placed in an injection mold, and the main body 13 of the bracket 1 is formed by injection molding based on the preform 120 and the guide rod 11. After the main body 13 of the bracket 1 is injection molded, the top limit portion 1219 can be completely covered in the main body 13 of the bracket 1 without being exposed.

[0079] Referring to the accompanying drawings of the present invention Figure 8 and Fig. 9 ,exist Figures 1 to 7D On the basis of the illustrated embodiment and its variant embodiment and optional embodiment, the driving device 100 further includes a base 4, wherein the carrier 2 and the bracket 1 are movably accommodated in the base 4, the bracket 1 is arranged between the base 4 and the carrier 2, and the driving component 3 is not only configured to drive the carrier 2 to move relative to the bracket 1 along the extension direction of the guide rod 11 to achieve the focus or zoom function of the camera module, but also configured to drive the bracket 1 to move relative to the base 4 in a plane perpendicular to the extension direction of the guide rod 11 to achieve the optical image stabilization function of the camera module. Correspondingly, the driving component 3 also includes a second coil 321 and a second magnet 322, wherein one of the second coil 321 and the second magnet 322 is arranged on the bracket 1, and the other is arranged on the base 4, and the second coil 321 and the second magnet 322 are arranged opposite to each other.

[0080] exist Figure 8 and Fig. 9 In the embodiment shown, the driving device 100 is implemented as an external OIS and internal AF architecture. It can be understood that in some embodiments of the present invention, Figures 1 to 7D On the basis of the illustrated embodiment and its variant embodiments and optional embodiments, the bracket 1 is used as the outermost fixed structure, and an anti-shake structure is further provided in the carrier 2 to realize the architecture of external AF and internal OIS.

[0081] Referring to the accompanying drawings of the present invention Fig.10 and Fig.11 According to another embodiment of the present invention, a support 1 and a driving device 100 are explained. Figures 1 to 7DThe difference between the illustrated embodiment and its variant embodiment and the optional embodiment is that the driving device 100 includes a bracket 1, a driving assembly 3 and a base 4, wherein the bracket 1 is movably accommodated in the base 4, the guide rod 11 of the bracket 1 is arranged on the outside of the bracket 1 in a manner facing the base 4, and the driving assembly 3 is configured to drive the bracket 1 to move relative to the base 4 along the extension direction of the guide rod 11, thereby realizing the focus or zoom function of the camera module. In the relative movement relationship between the bracket 1 and the base 4, the bracket 1 can be regarded as a mover and the base 4 can be regarded as a stator. The bracket 1 is driven to move relative to the base 4 by the driving assembly 3, and then the optical lens of the camera module as a whole or a part of the optical lens is driven by the bracket 1 to move along the optical axis of the optical lens to realize the focus or zoom function of the camera module.

[0082] for Fig.10 and Fig.11 The bracket 1 shown, its manufacturing process, and FIG. 5A to FIG. 5G , FIG. 7A to FIG. 7D The difference between the embodiment shown in the figure and its variant embodiment and the optional embodiment is that when the fixing portion 1215 is bent to form the bearing portion 1216 and the side limiting portion 1217, the bending method of the fixing portion 1215 is different from that of the fixing portion 1215. Figure 5B The bending modes shown in the figure are mirror-symmetrical to each other. When the fixing portion 1215 is bent to form the bearing portion 1216, the side limiting portion 1217 and the top limiting portion 1219, the bending mode of the fixing portion 1215 is the same as that of the fixing portion 1215. Figure 7B The bending modes shown are mirror-symmetrical to each other, so that the guide rod 11 can be finally embedded in the outer side of the bracket 1 .

[0083] Those skilled in the art will appreciate that the above embodiments are merely examples, wherein features of different embodiments may be combined with each other to obtain implementation methods that are easily conceivable based on the contents disclosed in the present invention but are not explicitly indicated in the drawings.

[0084] Those skilled in the art should understand that the above description and the embodiments shown in the drawings are only for illustrative explanation of the present invention, rather than for limitation of the present invention. All equivalent implementations, modifications and improvements within the spirit of the present invention should be included in the protection scope of the present invention.
