[0143] Please refer to Figures 1-2 , Figure 1 Fig. 1 is a perspective view of an optical element driving mechanism according to an embodiment of the present application, and Figure 2 Fig. 2 is an exploded view of the optical element driving mechanism according to an embodiment of the present application. The optical element driving mechanism 100 can be an optical camera module configured to carry and drive an optical element OE.

[0144] The optical element driving mechanism 100 can be installed in various electronic devices or portable electronic devices, such as a smartphone, for a user to perform image extraction functions. In this embodiment, the optical element driving mechanism 100 can be a voice coil motor (VCM) with an auto focus (AF) function, but the present application is not limited thereto. In other embodiments, the optical element driving mechanism 100 can also have an auto focus (AF) and optical image stabilization (OIS) function.

[0145] As shown in Figure 2 , the optical element driving mechanism 100 can include a fixed assembly FA, a movable portion 108, and a driving assembly DA. The movable portion 108 is configured to be connected to the aforementioned optical element OE, and the movable portion 108 can move relative to the fixed assembly FA. The driving assembly DA is configured to drive the movable portion 108 to move relative to the fixed assembly FA.

[0146] In this embodiment, the fixed assembly FA includes a housing 102 and a base 112, and the housing 102 is fixedly connected to the base 112 along a main axis MX to form a receiving space 1023, thereby accommodating the optical element OE. The housing 102 can have a first opening OP1, and when viewed along the main axis MX, the optical element OE is exposed from the first opening OP1. The optical element OE can be a reflective prism, but is not limited thereto.

[0147] like Figure 1 and Figure 2 As shown, the housing 102 also has a second opening OP2, and when viewed along a first axis AX1, the optical element OE is exposed through the second opening OP2. The first opening OP1 is connected to the second opening OP2, and an external ray LT enters the optical element OE along an optical axis OX after entering the first opening OP1, is then reflected by a reflective surface OES of the optical element OE, and then exits along the first axis AX1 from the optical element OE and the second opening OP2.

[0148] In this embodiment, the movable part 108 is movably connected to the base 112. Specifically, as... Figure 2 As shown, the optical element driving mechanism 100 may further include an elastic element 105 connected between the movable part 108 and the base 112. The elastic element 105 may have an outer connecting end 1051, an inner connecting end 1052, and a flexible part 1053. The outer connecting end 1051 is fixedly connected to the movable part 108, the inner connecting end 1052 is fixedly connected to the base 112, and the flexible part 1053 is connected between the outer connecting end 1051 and the inner connecting end 1052.

[0149] Based on this configuration, the movable part 108 is suspended in the base 112 by the elastic element 105, and the movable part 108 can move relative to the base 112 by the elastic element 105.

[0150] Please refer to the following: Figures 2-4 . Figure 3 A top view shows a portion of the structure of an optical element driving mechanism 100 according to an embodiment of the present invention, and Figure 4 This is a perspective view of a portion of the structure of an optical element driving mechanism 100 according to an embodiment of the present invention. In order to enable the movable part 108 to carry heavier optical elements OE and to further improve the stability of the optical element driving mechanism 100, the optical element driving mechanism 100 may further include two first elastic elements 106 and two second elastic elements 110, connected to the movable part 108 and the base 112.

[0151] Similarly, such as Figure 2 and Figure 3 As shown, two first elastic elements 106 are connected between the movable part 108 and the base 112, and each first elastic element 106 may have a first connecting end 1061, a second connecting end 1062 and a first flexible part 1063.

[0152] The first connecting end 1061 is fixedly connected to the movable portion 108, the second connecting end 1062 is fixedly connected to the base 112, and the first flexible portion 1063 is connected between the first connecting end 1061 and the second connecting end 1062.

[0153] Similarly, as shown in Figure 4 , two second elastic elements 110 are connected between the movable portion 108 and the base 112, and each second elastic element 110 has a third connecting end 1101, a fourth connecting end 1102, and a second flexible portion 1103.

[0154] The third connecting end 1101 is fixedly connected to the movable portion 108, the fourth connecting end 1102 is fixedly connected to the base 112, and the second flexible portion 1103 is connected between the third connecting end 1101 and the fourth connecting end 1102.

[0155] Notably, as shown in Figure 4 , the base 112 can have two bottom openings 1123, and the two second elastic elements 110 are respectively located in the two bottom openings 1123. When viewed along the main axis MX (Z-axis), the second elastic elements 110 are exposed by the bottom openings 1123. Based on such a configuration, the height of the optical element driving mechanism 100 in the Z-axis direction can be reduced to achieve miniaturization.

[0156] In addition, as shown in Figure 4 , when viewed along the main axis MX, the first connecting end 1061 is completely overlapped with the third connecting end 1101, and the first flexible portion 1063 is completely overlapped with the second flexible portion 1103 of the second elastic element. Based on such a configuration, the movable portion 108 can be more stable when moving.

[0157] Notably, in this embodiment, the elastic elements 105, the first elastic elements 106, and the second elastic elements 110 can be metal elastic springs, but are not limited thereto. In addition, the number of the elastic elements 105, the first elastic elements 106, and the second elastic elements 110 is not limited to this embodiment.

[0158] Then, back to Figure 2 , in this embodiment, the optical element driving mechanism 100 further includes a guide element GB disposed between the movable portion 108 and the base 112. The guide element GB can be a spherical ball configured to guide the movement of the movable portion 108 relative to the base 112.

[0159] As shown in Figure 2As shown, the guide element GB can define a first rotation axis RX1 and a second rotation axis RX2, and the driving assembly DA can drive the movable portion 108 to rotate relative to the base 112 about the first rotation axis RX1, and the driving assembly DA can also drive the movable portion 108 to rotate relative to the base 112 about the second rotation axis RX2. The second rotation axis RX2 is perpendicular to the first rotation axis RX1.

[0160] As shown, the first connection end 1061 is closer to the guide element GB than the second connection end 1062 when viewed along the main axis MX. Since the first connection end 1061 is closer to the second rotation axis RX2 than the second connection end 1062, the moment generated by the first connection end 1061 relative to the second rotation axis RX2 is smaller, and thus the movable portion 108 can be more stable when rotating about the second rotation axis RX2. Figure 3 As shown, the driving assembly DA can include a first driving element MG1 and a first coil CL1, and the first driving element MG1 is fixedly disposed on the bottom of the first movable portion 108.

[0161] Figure 2 Correspondingly, the optical element driving mechanism 100 can further include a circuit assembly 115, and the first coil CL1 is disposed on the circuit assembly 115. The circuit assembly 115 is fixedly disposed on the bottom of the base 112, and the circuit assembly 115 is, for example, a flexible circuit board (FPC board), but is not limited thereto.

[0162] In this embodiment, the first driving element MG1 is configured to generate a first electromagnetic driving force MF1 by inducting the first coil CL1 to drive the movable portion 108 to rotate relative to the base 112 about the first rotation axis RX1. For example, the movable portion 108 can perform a pitch action relative to the base 112.

[0163] In this embodiment, the driving assembly DA can further include a second driving element MG2, a third driving element MG3, a second coil CL2, and a third coil CL3, and the second driving element MG2 and the third driving element MG3 are disposed on the movable portion 108.

[0164] Among them, the first driving element MG1, the second driving element MG2, and the third driving element MG3 can be a magnet, for example, a multi-pole magnet, but are not limited thereto.

[0165]

[0166] ​​In this embodiment, the optical element driving mechanism 100 can further include a first side body assembly 104 and a second side body assembly 109, which are disposed on the base 112, the second coil CL2 is disposed on the first side body assembly 104, and the third coil CL3 is disposed on the second side body assembly 109.

[0167] As shown in Figure 2 , the second driving element MG2 is configured to generate a second electromagnetic driving force MF2 by induction with the second coil CL2, and the third driving element MG3 is configured to generate a third electromagnetic driving force MF3 by induction with the third coil CL3, so that the second electromagnetic driving force MF2 and the third electromagnetic driving force MF3 can jointly drive the movable part 108 to rotate relative to the base 112 about the second rotation axis RX2.

[0168] Among them, the directions of the second electromagnetic driving force MF2 and the third electromagnetic driving force MF3 are opposite. For example, when the second electromagnetic driving force MF2 is towards the -Y axis, the third electromagnetic driving force MF3 is towards the +Y axis, so that the second electromagnetic driving force MF2 and the third electromagnetic driving force MF3 can jointly drive the movable part 108 to rotate clockwise about the second rotation axis RX2. (When looking from top to bottom along the main axis MX in Figure 2

[0169] On the contrary, when the second electromagnetic driving force MF2 is towards the +Y axis, the third electromagnetic driving force MF3 is towards the -Y axis, so that the second electromagnetic driving force MF2 and the third electromagnetic driving force MF3 can jointly drive the movable part 108 to rotate counterclockwise about the second rotation axis RX2.

[0170] Next, please refer to Figure 5 and Figure 6 . Figure 5 is an exploded view of part of the structure of the optical element driving mechanism 100 according to an embodiment of the present application, and Figure 6 is an exploded view of part of the structure of the first side body assembly 104 according to an embodiment of the present application. It should be noted that the second side body assembly 109 and the first side body assembly 104 are symmetrically arranged, and their constituent structures and element configurations are similar to those of the first side body assembly 104, so the following paragraphs will only be described with the first side body assembly 104.

[0171] In this embodiment, the first side body assembly 104 can have a first base 1040, a first circuit 1041 and a second circuit 1043, the first base 1040 has a non-metal material, and the first circuit 1041 and the second circuit 1043 have a metal material. Specifically, the first circuit 1041 and the second circuit 1043 are disposed in the first base 1040 by insert molding.

[0172] As​Figure 5 and Figure 6 As shown, the second coil CL2 is disposed on the first substrate 1040. Specifically, the first substrate 1040 has a first substrate surface 104S and a first positioning portion 104P. The first positioning portion 104P protrudes from the first substrate surface 104S along a second axis AX2, and the second coil CL2 is positioned on the first positioning portion 104P. The second axis AX2 is perpendicular to the first axis AX1.

[0173] Furthermore, in this embodiment, the first side body assembly 104 may also have a first fixed end 1044 and a second fixed end 1045, which are fixedly connected to the first base 1040. The first base 1040, the first fixed end 1044 and the second fixed end 1045 may be made of plastic material and may be integrally formed, but are not limited thereto.

[0174] The second coil CL2 has a first lead WR1 and a second lead WR2, which are respectively wound and fixed to the first fixed end 1044 and the second fixed end 1045, so that the first lead WR1 and the second lead WR2 are configured to be electrically connected to the first line 1041 and the second line 1043, respectively.

[0175] Specifically, a portion of the first line 1041 and the second line 1043 will be exposed from the first substrate 1040 to facilitate the soldering of the first lead WR1 and the second lead WR2.

[0176] Furthermore, when viewed along the second axis AX2, the first base 1040 has a polygonal structure. When viewed along the second axis AX2, the first fixed end 1044 and the second fixed end 1045 are located on different sides of the polygonal structure, for example, on the left and right sides. Based on this configuration, the first lead WR1 and the second lead WR2 can be easily wound around the first fixed end 1044 and the second fixed end 1045.

[0177] In addition, such as Figure 5 As shown, when viewed along the first axial direction AX1, the first substrate 1040 has a first thickness TH1, and the first thickness TH1 is greater than 0.2 mm. This size configuration facilitates assembly and also achieves miniaturization.

[0178] like Figure 5 and Figure 6 As shown, the first line 1041 and the second line 1043 each have a first external contact 1046 and a second external contact 1047, respectively, configured to be electrically connected to an external circuit.

[0179] When viewed along the second axis AX2, the first external contact 1046 and the first fixed end 1044 are located on different sides of the first base 1040. When viewed along the second axis AX2, the second external contact 1047 and the first fixed end 1044 are located on different sides of the first base 1040.

[0180] Furthermore, the optical element driving mechanism 100 may also include a side circuit assembly 114, which is fixedly disposed in the first substrate 1040. The side circuit assembly 114 is, for example, a flexible circuit board or a general circuit board, which may have a plurality of third external contacts 1141, and when the side circuit assembly 114 is disposed on the first substrate 1040, these third external contacts 1141 are disposed between the first external contact 1046 and the second external contact 1047.

[0181] It is worth noting that these third external contacts 1141 are located on the same side of the first external contact 1046 as the first external contact 1040, for example, on the bottom side of the first base 1040. In addition, when viewed along the first axial direction AX1, these third external contacts 1141 overlap with the first external contact 1046 and the second external contact 1047.

[0182] Based on this configuration, it is convenient to solder these third external contacts 1141, the first external contacts 1046, and the second external contacts 1047. Specifically, these third external contacts 1141, the first external contacts 1046, and the second external contacts 1047 are configured to be soldered to the electrical contacts 1151 of the circuit assembly 115, so as to be electrically connected to the aforementioned external circuit via the circuit assembly 115.

[0183] Furthermore, such as Figure 5 and Figure 6 As shown, the optical element driving mechanism 100 also includes a first reinforcing element STP1, which is fixedly connected to the side circuit assembly 114. The first reinforcing element STP1 is made of, for example, metal. Based on the configuration of the first reinforcing element STP1, the overall structural strength of the first side assembly 104 can be increased, and the side circuit assembly 114 can also be reliably positioned.

[0184] Please refer to the following: Figures 5-7 . Figure 7 For an optical element driving mechanism 100 according to an embodiment of the present invention, along Figure 1 A cross-sectional view of the midline segment AA. (See diagram below.) Figure 7 As shown, when viewed along the first axis AX1 (Y-axis), there is a first shortest distance MD1 between the base 112 and the housing 102, and when viewed along the first axis AX1, there is a second shortest distance MD2 between the first reinforcing element STP1 and the housing 102.

[0185] Further, the side circuit assembly 114 has a third shortest distance MD3 from the housing 102 when viewed along the first axial direction AX1, and the first side body assembly 104 has a fourth shortest distance MD4 from the housing 102 when viewed along the first axial direction AX1.

[0186] In some embodiments, the fourth shortest distance MD4 is greater than the third shortest distance MD3, the third shortest distance MD3 is greater than the second shortest distance MD2, the second shortest distance MD2 is greater than the first shortest distance MD1, the second shortest distance MD2 is greater than 0, and the first shortest distance MD1 can be slightly greater than 0 (e.g., a distance caused by a tolerance), but is not limited thereto. In some embodiments, the first shortest distance MD1 can be equal to 0.

[0187] Based on such a configuration, the problem of the side circuit assembly 114 and the first side body assembly 104 colliding with the housing 102 and causing damage can be avoided.

[0188] Continuing to refer to Figures 5-7 , as shown in Figures 5-7 , the first side body assembly 104 can further have a first opening 104H that penetrates the first base 1040 and the first positioning portion 104P, and the optical element driving mechanism 100 can further have a first sensor SE1 disposed on the side circuit assembly 114 and located in the first opening 104H.

[0189] As shown in Figure 5 and Figure 7 , the first sensor SE1 is exposed by the first opening 104H when viewed along the second axial direction AX2. Further, as shown in Figure 5 , the second driving element MG2 corresponds to the second coil CL2, and the base 112 further has a second opening 112H corresponding to the first opening 104H.

[0190] The second driving element MG2 is exposed by the second opening 112H when viewed along the second axial direction AX2. Based on the configuration of the above openings, the accuracy of the first sensor SE1 sensing the magnetic field of the second driving element MG2 can be ensured.

[0191] The positioning structure on the base 112 will be described next. In this embodiment, the base 112 can further have a first receiving groove RG1 configured to receive the first side body assembly 104. The base 112 can further have a first surface SF1 facing the housing 102, and the first receiving groove RG1 is recessed from the first surface SF1.

[0192] The base 112 can further have a second receiving groove RG2 configured to receive the first lead WR1 and the second lead WR2. The base 112 can further have a second surface SF2 located in the first receiving groove RG1, and the second receiving groove RG2 is recessed from the second surface SF2.

[0193] The base 112 can further have a third surface SF3 located in the second receiving groove RG2. Notably, the third surface SF3 has a difference from the second surface SF2, i.e., the second surface SF2 and the third surface SF3 are not coplanar.

[0194] Further, the base 112 can further have a third receiving groove RG3 configured to receive a portion of the first side body assembly 104, and the third receiving groove RG3 is connected to the second receiving groove RG2. Then, the optical element driving mechanism 100 can further have a first adhesive element AD1 configured to connect the first side body assembly 104 and the base 112. The first adhesive element AD1 is disposed in the first receiving groove RG1, the second receiving groove RG2, and the third receiving groove RG3, and is configured to directly contact the second surface SF2 and the third surface SF3. The first adhesive element AD1 is, for example, a thermosetting adhesive, but is not limited thereto.

[0195] The base 112 can further have a fourth receiving groove RG4 and a fifth receiving groove RG5 configured to receive the first fixed end portion 1044 and the second fixed end portion 1045, respectively, and the base 112 can further have a sixth receiving groove RG6 and a seventh receiving groove RG7 configured to be connected to the fourth receiving groove RG4 and the fifth receiving groove RG5, respectively.

[0196] The base 112 can further have a fourth surface SF4 located in the sixth receiving groove RG6. The base 112 can further have a fifth surface SF5 connected to the fourth surface SF4 and the third surface SF3, and the fifth surface SF5 is not parallel to the fourth surface SF4 and the third surface SF3. With respect to the third surface SF3 and the fourth surface SF4, the fifth surface SF5 is an inclined surface.

[0197] Further, the optical element driving mechanism 100 can further have a second adhesive element AD2 disposed in the fourth receiving groove RG4 to the seventh receiving groove RG7. The second receiving groove RG2 is connected to the fourth receiving groove RG4 to the seventh receiving groove RG7, and the second adhesive element AD2 is configured to directly contact the first fixed end portion 1044, the second fixed end portion 1045, the fourth receiving groove RG4, the fifth receiving groove RG5, and the side circuit assembly 114.

[0198] After the first side body assembly 104, the side circuit assembly 114 and the first reinforcing element STP1 are disposed in the first receiving groove RG1, the second adhesive element AD2 is configured to flow into the second receiving groove RG2 via the fourth receiving groove RG4 and the fifth receiving groove RG5, and the second adhesive element AD2 is configured to flow into the first receiving groove RG1 via the sixth receiving groove RG6 and the seventh receiving groove RG7.

[0199] The second adhesive element AD2 may differ from the first adhesive element AD1. For example, the second adhesive element AD2 may be a photocurable adhesive, allowing the first side body assembly 104 to be fixed onto the base 112 first, and then the optical element drive mechanism 100 to be placed in an oven to cure the first adhesive element AD1. Based on this design, the first side body assembly 104 can be quickly installed onto the base 112 without falling off, and the process is also made more convenient.

[0200] Please refer to the following: Figure 2 and Figure 8 . Figure 8 This is a perspective view of the movable part 108 and the guiding element GB according to an embodiment of the present invention. In this embodiment, the optical element driving mechanism 100 may further include a reinforcing member YK1 disposed in the movable part 108. The reinforcing member YK1 is made of, for example, a metal material, and the guiding element GB is in direct contact with the reinforcing member YK1.

[0201] like Figure 8 As shown, in order to avoid the guide element GB from pushing the reinforcing member YK1 for a long time and causing the reinforcing member YK1 to be dented, in this embodiment, the optical element driving mechanism 100 may also include a first reinforcing element 130, which is disposed on the movable part 108 and located between the reinforcing member YK1 and the guide element GB.

[0202] The first reinforcing element 130 is made of, for example, metal, and the hardness of the first reinforcing element 130 may be greater than the hardness of the reinforcing member YK1. The first reinforcing element 130 may have a notch 1301 configured to receive a portion of the guiding element GB. The notch 1301 may have a first contact edge 1302, a second contact edge 1303, and a third contact edge 1304.

[0203] When viewed along the first axial direction AX1, the notch 1301 has a triangular structure, and the guide element GB simultaneously contacts the first contact edge 1302, the second contact edge 1303, and the third contact edge 1304. This configuration prevents the reinforcing member YK1 from being pushed by the guide element GB, thus avoiding a depression.

[0204] Please refer to the following: Figure 9 . Figure 9This is a perspective view of the movable part 108 and the guiding element GB according to another embodiment of the present invention. In this embodiment, the optical element driving mechanism 100 may further include a buffer element 132 disposed between the reinforcing member YK1 and the first reinforcing element 130.

[0205] The buffer element 132 is made of an elastic material, such as rubber, but is not limited thereto. Based on the configuration of the buffer element 132, the pressure of the guide element GB on the reinforcing member YK1 can be absorbed, thereby further increasing the service life of the reinforcing member YK1.

[0206] Please refer to the following: Figure 10 . Figure 10 This is a perspective view of the movable part 108 and the guiding element GB according to another embodiment of the present invention. This embodiment is similar to... Figure 8 Similar to the embodiments in the previous one, the difference is that in this embodiment, the optical element driving mechanism 100 may also have three second reinforcing elements 133 disposed between the reinforcing member YK1 and the first reinforcing element 130.

[0207] The second reinforcing element 133 may be a sphere, and its size is smaller than that of the guiding element GB. The second reinforcing element 133 and the guiding element GB may be made of, for example, ceramic material, but are not limited thereto. Based on the configuration of three second reinforcing elements 133, the pressure of the guiding element GB on the reinforcing member YK1 can be distributed to further increase the service life of the reinforcing member YK1.

[0208] In addition, similar to the aforementioned embodiments, in this embodiment, a buffer element 132 may also be provided between the second reinforcing element 133 and the reinforcing member YK1 to further prevent the reinforcing member YK1 from being crushed.

[0209] In this embodiment, please refer to the following: Figure 2 , Figure 11 and Figure 12 . Figure 11 This is a perspective view of a portion of the structure of an optical element driving mechanism 100 according to an embodiment of the present invention, and Figure 12 This is a perspective view of a portion of the structure of an optical element driving mechanism 100 according to an embodiment of the present invention.

[0210] The optical element drive mechanism 100 also has two first stop assemblies 140, which are fixedly mounted on the movable part 108. The first stop assemblies 140 are configured to abut against the housing 102 when the movable part 108 moves, so as to avoid damage to the movable part 108 and the optical element OE due to collision.

[0211] Each first stopper assembly 140 has a first base 141 and a first stopper 142, the first base 141 has a metal material, and the first stopper 142 has a plastic material, but not limited thereto. For example, the first stopper 142 can be silicone.

[0212] The first base 141 has a first through hole 1411 and a second through hole 1412, and a portion of the first stopper 142 is located in the first through hole 1411 and the second through hole 1412. Specifically, the first base 141 is disposed in the first stopper 142 by insert molding.

[0213] Further, the first base 141 also has a first side edge 1413 and a second side edge 1414, and the center line LN1 of the first through hole 1411 and the second through hole 1412 passes through the first side edge 1413 and the second side edge 1414. The first side edge 1413 is, for example, the top edge of the first base 141, and the second side edge 1414 is, for example, the front side edge of the first base 141. That is, the first through hole 1411 and the second through hole 1412 are diagonally arranged.

[0214] Further, as shown in Figure 2 As shown in Figure 12 The optical element driving mechanism 100 can further have a second stopper assembly 150 fixedly disposed at the bottom of the movable portion 108. The second stopper assembly 150 is arranged to abut against the base 112 when the movable portion 108 moves, so as to avoid the problem of damage caused by the collision between the movable portion 108 and the base 112.

[0215] The second stopper assembly 150 has a second base 151 and two second stoppers 152, the second base 151 has a metal material, and the second stopper 152 has a plastic material, but not limited thereto. For example, the second stopper 152 can be silicone.

[0216] The second base 151 has a third through hole 1511 and a fourth through hole 1512, and a portion of the second stopper 152 is located in the third through hole 1511 and the fourth through hole 1512. Specifically, the second base 151 is partially disposed in the two second stoppers 152 by insert molding.

[0217] The second base 151 can further have a third side edge 1513 and a fourth side edge 1514, and the center line LN2 of the third through hole 1511 and the fourth through hole 1512 passes through the fourth side edge 1514 but not the third side edge 1513.

[0218] It is worth noting that since the first base 141 can serve as a support for the first stop component 140, and the second base 151 can serve as a support for the second stop component 150, the mechanical arm can clamp the first base 141 and the second base 151 to install the first stop component 140 and the second stop component 150 on the movable part 108, without the need for manual installation by the operator, achieving the purpose of automated production.

Movable part 108 can be movably connected to the base 112 of fixed assembly FA by a elastic element 105. Furthermore, optical element driving mechanism 100 can also include two first elastic elements 106 and two second elastic elements 110, are connected to movable part 108 and base 112, to make movable part 108 more stable when moving relative to base 112.

[0221] In addition, the first side body assembly 104 can also include a first circuit 1041 and a second circuit 1043, which have metal material, and are disposed in the first base 1040 by insert molding. Therefore, the second coil CL2 can be electrically connected to another circuit board (circuit assembly 115) by the first circuit 1041 and the second circuit 1043. Such design not only can increase the convenience of welding, compared with the known flexible circuit board solution, the first side body assembly 104 can have higher structural strength and service life.
