Details are described below.

[0037] Referring to Figure 1 , Figure 2 , Figure 4 and Figure 7 , in an embodiment, the optical assembly comprises a lamp body 10 and a light guide 20; the lamp body 10 has a first through hole 11; the light guide 20 is fixed to the first through hole 11 through a connecting piece 30; wherein the connecting piece 30 comprises a main body part 31, a first limiting part 32 and a second limiting part 33, the end part of the light guide 20 is inserted into the main body part 31, and the main body part 31 is inserted into the first through hole 11; in the axial direction of the main body part 31, the first limiting part 32 and the second limiting part 33 are arranged at intervals; the two sides of the lamp body 10 in the axial direction of the first through hole 11 are selectively clamped between the first limiting part 32 and the second limiting part 33 to limit the relative position of the connecting piece 30 and the lamp body 10 in the axial direction of the first through hole 11; the second limiting part 33 is provided with a second through hole 50, and the surface of the lamp body 10 facing the second limiting part 33 is provided with a positioning hole 12, and the second through hole 50 is connected with the positioning hole 12 through a positioning piece to limit the relative position of the connecting piece 30 and the lamp body 10 in the circumferential direction of the first through hole 11.

[0038] The light guide 20 is fixed on the lamp body 10 through the connecting piece 30, specifically, the end of the light guide 20 is inserted on the main body part 31, which ensures the stability of the end of the light guide 20 relative to the lamp body 10, and the light can propagate according to the designed path, effectively preventing the light guide 20 from loosening and falling off due to vehicle vibration and impact; by adjusting the position of the connecting piece 30 in the first through hole 11, the lamp body 10 is clamped between the first limiting part 32 and the second limiting part 33 on both sides of the first through hole 11 in the axial direction, which can limit the relative position of the connecting piece 30 and the lamp body 10 in the axial direction of the first through hole 11, that is, the connecting piece 30 cannot move along the axial direction of the first through hole 11; in addition, the second through hole 50 is arranged on the first limiting part 32, and the surface of the lamp body 10 facing the first limiting part 32 is provided with a positioning hole 12, which is connected with the second through hole 50 through a positioning piece, which can limit the relative position of the connecting piece 30 and the lamp body 10 in the circumferential direction of the first through hole 11, that is, the connecting piece 30 (light guide 20) cannot rotate in the first through hole 11.

[0039] In this way, the relative position between the connecting piece 30 and the lamp body 10 is limited, and the connecting piece 30 cannot move relative to the lamp body 10, and at the same time the light guide 20 is fixed in the main body part 31, that is, the light guide 20 cannot move relative to the lamp body 10, which ensures the stability of the installation of the light guide 20, improves the quality of light propagation, and optimizes the driving experience; and the connecting piece 30 is installed in the first through hole 11, which is convenient to operate and effectively improves the assembly efficiency.

[0040] It should be noted that in some embodiments, the connecting piece 30 is provided with a mounting hole, the end of the light guide 20 is inserted in the mounting hole, and a positioning block 311 is arranged on the inner wall of the mounting hole, which is arranged on the inner wall of the mounting hole in the circumferential direction of the mounting hole, which can limit the relative position of the end of the light guide 20 and the connecting piece 30 in the radial direction of the mounting hole, and through the arrangement of the positioning block 311, the stability of the position between the end of the light guide 20 and the connecting piece 30 can be further limited, which is beneficial to the light propagation.

[0041] Referring to Figure 1 and Figure 7 In an embodiment, the two ends of the first through hole 11 in the axial direction are a first end 111 and a second end 112; the first limiting part 32 includes a plurality of limiting sub-parts 321 arranged in the circumferential direction of the main body part 31, and the inner wall of the first through hole 11 near the first end 111 is provided with a plurality of abutting blocks 113, and the abutting blocks 113 are arranged in the circumferential direction of the first through hole 11, and the adjacent abutting blocks 113 form a avoiding space 60 for the limiting sub-parts 321 to pass through, the limiting sub-parts 321 pass through the avoiding space 60 in the direction from the second end 112 to the first end 111, and rotate to abut against the surface of the abutting block 113 away from the second end 112, and the second limiting part 33 abuts against the surface of the lamp body 10 near the second end 112.

[0042] In actual use, the connecting piece 30 is inserted into the first through hole 11 along the direction from the second end 112 to the first end 111, the limiting sub portion 321 passes through the avoiding space 60 until the limiting sub portion 321 is above the abutting block 113 (the same below), at this time, the second limiting portion 33 abuts against the surface of the lamp body 10 close to the second end 112, the limiting sub portion 321 is made to abut against the abutting block 113 by rotating the limiting sub portion 321, the position of the connecting piece 30 in the axial direction of the first through hole 11 is limited, the structure is simple, only needs to be inserted into the first through hole 11 and then rotated to limit the position of the connecting piece 30, convenient to use, and improves the assembly efficiency. Figure 7 View, same below), at this time, the second limiting portion 33 abuts against the surface of the lamp body 10 close to the second end 112, the limiting sub portion 321 is made to abut against the abutting block 113 by rotating the limiting sub portion 321, the position of the connecting piece 30 in the axial direction of the first through hole 11 is limited, the structure is simple, only needs to be inserted into the first through hole 11 and then rotated to limit the position of the connecting piece 30, convenient to use, and improves the assembly efficiency.

[0043] It should be noted that in the embodiment, the limiting sub portion 321 and the abutting block 113 are respectively provided with three, which can limit the position of the connecting piece 30 in the axial direction of the first through hole 11, and also ensure the stability of the connecting piece 30 after the position is limited; in some embodiments, the limiting sub portion 321 and the abutting block 113 can also be provided with other numbers, the more the number of the limiting sub portion 321, although the stability of the position of the connecting piece 30 can be ensured, but the increase in the number is not conducive to the abutting cooperation of the limiting sub portion 321 and the abutting block 113, and the actual use should be considered comprehensively according to the size of the connecting piece 30 and other factors.

[0044] Referring to Figure 3 , the surface of the abutting block 113 away from the second end 112 is provided with a stop protrusion 1131 for limiting the rotation angle of the limiting sub portion 321.

[0045] The stop protrusion 1131 is protruded on the surface of the abutting block 113 away from the second end 112, in the process of rotating the connecting piece 30 (that is, the limiting sub portion 321 is rotated to abut against the surface of the abutting block 113 away from the second end 112), the limiting sub portion 321 is rotated to abut against the stop protrusion 1131 and stops rotating, at this time, the limiting sub portion 321 is rotated to the preset position.

[0046] In this way, the rotation of the limiting sub portion 321 to the position can be ensured, and the rotation of the limiting sub portion 321 by too much or not enough can be avoided; if the stop protrusion 1131 is not provided when the limiting sub portion 321 is rotated to the preset position, the limiting sub portion 321 can continue to rotate to another avoiding space 60, which affects the tightness of the connection between the limiting sub portion 321 and the abutting block 113.

[0047] In an embodiment, when the limiting sub-portion 321 abuts against the stop bump 1131, the area of the normal projection of the limiting sub-portion 321 on the plane where the surface of the abutting block 113 faces the limiting sub-portion 321 is S1 mm2, the area of the normal projection of the part of the limiting sub-portion 321 abutting against the abutting block 113 on the plane where the surface of the abutting block 113 faces the limiting sub-portion 321 is S2 mm2, and the following condition is met: 1 / 2≤S2 / S1≤2 / 3.

[0048] By setting the ratio of the area of the part of the limiting sub-portion 321 abutting against the abutting block 113 to the area of the limiting sub-portion 321 (the area of the surface of the limiting sub-portion 321 facing the abutting block 113), the stability of the connection between the limiting sub-portion 321 and the abutting block 113 can be ensured, and thus the stability of the connecting piece 30 in the first through hole 11 and the stability of the light guide 20 can be ensured, and the propagation quality of the light can be improved.

[0049] When the ratio of S2 / S1 is less than 1 / 2, that is, the area of the part of the limiting sub-portion 321 abutting against the abutting block 113 is small, the stability of the connection between the limiting sub-portion 321 and the abutting block 113 is not good, and the vibration or impact during the use of the vehicle can cause the limiting sub-portion 321 to fall off from the abutting block 113, which is not conducive to the stability of the connection. When the ratio of S2 / S1 is greater than 2 / 3, the area of the contact between the limiting sub-portion 321 and the abutting block 113 is large, that is, when the limiting sub-portion 321 rotates, the friction between the limiting sub-portion 321 and the abutting block 113 is large, and a large friction needs to be overcome to rotate the limiting sub-portion 321, which increases the labor intensity of assembly and is not conducive to the improvement of assembly efficiency. In summary, when the ratio of S2 / S1 is within the above range, the stability of the connection between the limiting sub-portion 321 and the abutting block 113 can be ensured, and the labor intensity can be reduced and the assembly efficiency can be improved.

[0050] Referring to Figure 5 and Figure 7 In an embodiment, the first through hole 11 has a first end 111 and a second end 112 in the axial direction, and the second limiting portion 33 is close to the second end 112. The surface of the lamp body 10 close to the second end 112 is provided with a pressing bump 13. The second limiting portion 33 includes a resilient sub-portion 331 and a mounting sub-portion 332. The mounting sub-portion 332 is connected to the main body portion 31, and the resilient sub-portion 331 is arranged on the surface of the mounting sub-portion 332 facing the first limiting portion 32. When the connecting piece 30 is connected to the first through hole 11, the mounting sub-portion 332 is rotated so that the pressing bump 13 is pressed against the resilient sub-portion 331, and the first limiting portion 32 abuts against the surface of the lamp body 10 close to the first end 111.

[0051] By setting the extrusion protrusion 13 and the elastic sub-part 331, when the connecting member 30 is inserted into the first through hole 11, the extrusion protrusion 13 squeezes the elastic sub-part 331, and the elastic sub-part 331 is deformed under pressure. Such a setting can ensure the stability of the connection between the extrusion protrusion 13 and the elastic sub-part 331, and can ensure that the first limiting part 32 and the surface of the lamp body 10 close to the first end 111 are pressed more tightly, thereby improving the stability of the connecting member 30.

[0052] It should be noted that, in this embodiment, the extrusion protrusion 13 and the elastic sub-portion 331 are connected by rotating the elastic sub-portion 331 until it is crimped with the extrusion protrusion 13. For example, on the basis of the above embodiment, the connecting member 30 is inserted into the first through hole 11 along the direction of the second end 112 toward the first end 111 until the limiting sub-portion 321 passes through the avoidance space 60 to the top of the abutment block 113, and the connecting member 30 is rotated. The limiting sub-portion 321 abuts against the surface of the abutment block 113 away from the second end 112, and during the rotation of the connecting member 30, the elastic sub-portion 331 rotates to be crimped with the extrusion protrusion 13. This arrangement improves the stability of the position of the connecting member 30 in the first through hole 11, is convenient to use, and improves assembly efficiency.

[0053] It should also be noted that, in some embodiments, the end of the elastic sub-portion 331 (the end that first contacts the crimping protrusion during the rotation of the connecting member 30) is provided with a guiding slope, which can facilitate the connection and extrusion of the extrusion protrusion 13 and the elastic sub-portion 331.

[0054] See Figure 1 In one embodiment, a weakening groove 40 is provided at the connection between the mounting sub-portion 332 and the main body portion 31 , and the weakening groove 40 is provided between the elastic sub-portion 331 and the main body portion 31 .

[0055] When the elastic sub-portion 331 contacts the pressing protrusion 13, the elastic sub-portion 331 is subjected to downward ( Figure 7 The squeezing force of the mounting sub-portion 332 and the main body 31 can be reduced by setting the weakening groove 40, thereby avoiding stress concentration and causing fracture of the mounting sub-portion 332 and the main body 31, and effectively improving the service life. At the same time, by setting the weakening groove 40, when the extrusion protrusion 13 squeezes the elastic sub-portion 331, the elastic sub-portion 331 can be easily deformed. Compared with the setting without the weakening groove 40, such a setting reduces the labor required for assembly, and does not require a lot of force to achieve the abutment between the elastic sub-portion 331 and the extrusion protrusion 13, which is conducive to improving the assembly efficiency.

[0056] See Figure 6In an embodiment, the peripheral side of the mounting sub-portion 332 is provided with a first limiting protrusion 3321, and the surface close to the second end 112 of the lamp body 10 is provided with a second limiting protrusion 14; the mounting sub-portion 332 is rotated so that the first limiting protrusion 3321 abuts against the second limiting protrusion 14 to limit the rotation angle of the mounting sub-portion 332.

[0057] When the mounting sub-portion 332 is rotated, the first limiting protrusion 3321 rotates with the mounting sub-portion 332 until the first limiting protrusion 3321 abuts against the second limiting protrusion 14, and the mounting sub-portion 332 stops rotating, at which time the mounting sub-portion 332 reaches the preset position (the extrusion protrusion 13 is in pressure contact with the elastic sub-portion 331).

[0058] In this way, the mounting sub-portion 332 can be guaranteed to be rotated to the right position, and the problem of excessive rotation or insufficient rotation of the mounting sub-portion 332 is avoided; without the second limiting protrusion 14, the mounting sub-portion 332 is prone to excessive rotation, so that the limiting sub-portion 321 and the extrusion protrusion 13 are separated again after the pressure contact is completed, which affects the stability of the connection of the connecting piece 30; when the rotation angle of the mounting sub-portion 332 is small, the extrusion protrusion 13 is easily bounced away by the elasticity of the elastic sub-portion 331, that is, the pressure contact state of the extrusion protrusion 13 and the elastic sub-portion 331 is unstable, which also affects the stability of the connection of the connecting piece 30 and the first through hole 11.

[0059] Referring to Figure 1 In an embodiment, the mounting sub-portion 332 has a cantilever 3322 extending from the main body portion 31 to a side away from the main body portion 31 in a radial direction of the main body portion 31, and the second through hole 50 is arranged at the end of the cantilever 3322 away from the main body portion 31.

[0060] The arrangement of the cantilever 3322 can facilitate the rotation of the mounting sub-portion 332 (the connecting piece 30), increase the force arm of rotation, reduce the force required for the rotation of the mounting sub-portion 332, reduce the labor intensity, guarantee the rotation of the connecting piece 30 to the right position, and stabilize the connection; the second through hole 50 is arranged at the end of the cantilever 3322 away from the main body portion 31, so that the second through hole 50 can be quickly and intuitively aligned with the positioning hole 12 during the rotation of the connecting piece 30, and the second through hole 50 is away from the main body portion 31, which provides installation space for the installation of the positioning piece, avoids interference between the positioning piece and the main body portion 31 during the installation of the positioning piece, and increases the assembly difficulty.

[0061] On the other hand, the application also relates to a vehicle lamp comprising any of the optical assemblies.

[0062] On the other hand, the application also relates to a vehicle comprising the vehicle lamp.
