[0053] Figure 1 The structural schematic diagram of the bonding jig in an embodiment of the present application is shown. Figure 2 The structural schematic diagram of the mirror in an embodiment of the present application is shown. Figure 3 The structural schematic diagram of the mounting bracket in an embodiment of the present application is shown. Figure 4 The structural schematic diagram of the pressure maintaining member in an embodiment of the present application is shown.

[0054] Please refer to Figures 1 - 4 , an embodiment of the present application provides a bonding jig 10, and the bonding jig 10 is used to bond the mirror 210 to the mounting bracket 220. The mirror 210 has a first curved surface 211 and a second curved surface 212 arranged opposite to each other. The mounting bracket 220 has a bearing curved surface 221 adapted to the first curved surface 211, and the first curved surface 211 of the mirror 210 is adapted to be bonded to the bearing curved surface 221 of the mounting bracket 220.

[0055] The bonding jig 10 includes a base 110, a positioning assembly 120 and a pressure maintaining member 130. The positioning assembly 120 is arranged on the base 110, and the positioning assembly 120 includes at least two positioning members 121. At least two first positioning holes 213 corresponding one-to-one and spaced apart are provided on the mirror 210. The first positioning holes 213 penetrate from the first curved surface 211 to the second curved surface 212. At least two second positioning holes 222 corresponding one-to-one and spaced apart are provided on the mounting bracket 220. The second positioning holes 222 penetrate from the bearing curved surface 221 of the mounting bracket 220 to the side of the mounting bracket 220 away from the first curved surface 211.

[0056] It can be that one end of at least two positioning members 121 close to the base 110 is detachably connected to the base 110. For example, one end of the positioning member 121 close to the base 110 is threadedly connected or clamped to the base 110. It can also be that one end of at least two positioning members 121 close to the base 110 is fixedly connected to the base 110, and no specific limitation is made here.

[0057] The number of the positioning members 121 can be two, three, four, five, six or more, and no specific limitation is made here.

[0058] The structures of the multiple positioning members 121 of the positioning assembly 120 may be the same or different, and no specific limitation is made here. Exemplarily, the structure of one of the positioning members 121 of the positioning assembly 120 is different from that of the remaining positioning members 121.

[0059] The pressure-holding member 130 has a pressure-holding surface 131 adapted to the second curved surface 212. The pressure-holding surface 131 is used to press against the second curved surface 212 along the direction from the second curved surface 212 to the first curved surface 211. At least two third positioning holes 132 are provided on the pressure-holding member 130, which are arranged at intervals and correspond one-to-one to at least two positioning members 121. The third positioning holes 132 penetrate from the side of the pressure-holding member 130 away from the second curved surface 212 to the pressure-holding surface 131 of the pressure-holding member 130.

[0060] Along the direction from the first curved surface 211 to the second curved surface 212, the positioning member 121 is sequentially and adaptively inserted through the corresponding second positioning hole 222, the corresponding first positioning hole 213, and the corresponding third positioning hole 132.

[0061] The cross-section of the first positioning member 121 in the direction perpendicular to the direction from the first curved surface 211 to the second curved surface 212 may include a square, a circle, a bow shape, a semi-circle, etc., as long as the first positioning member 121 can be respectively adapted to the corresponding second positioning hole 222, the corresponding first positioning hole 213, and the corresponding third positioning hole 132.

[0062] Since along the direction from the first curved surface 211 to the second curved surface 212, the positioning member 121 is sequentially and adaptively inserted through the corresponding second positioning hole 222, the corresponding first positioning hole 213, and the corresponding third positioning hole 132, therefore, at least two positioning members 121 can be used to improve the alignment accuracy of the mirror 210 with respect to the mounting bracket 220, and can also improve the alignment accuracy of the pressure-holding member 130 with respect to the mirror 210. In this way, the pressure-holding member 130 can be better used to press against the mirror 210 along the direction from the second curved surface 212 to the first curved surface 211. Furthermore, the mirror 210 can be better attached to the mounting bracket 220, reducing the situation that the mirror surface of the mirror 210 is offset due to alignment deviation during the installation of the mirror 210 on the mounting bracket 220, which even affects the anti-ghost image distortion function of the mirror 210. The alignment accuracy of the mirror 210 can be improved, and then the mirror 210 can be better used to solve the problem of ghost image distortion, and the mirror 210 can also be well used to achieve the function of compensating for the curvature of the windshield, thereby improving the quality of the image projected onto the windshield.

[0063] In addition, in the present application, the positioning member 121 is respectively adapted to the corresponding second positioning hole 222, the corresponding first positioning hole 213, and the corresponding third positioning hole 132. Thus, the alignment accuracy of the mirror 210 with respect to the mounting bracket 220 can be improved, and the alignment accuracy of the pressure maintaining member 130 with respect to the mirror 210 can also be improved. Thus, a smaller number of positioning members 121 can be used to align and fit the mirror 210 to the mounting bracket 220 (a glue solution can be provided on the side of the mounting bracket 220 facing the mirror 210, that is, a glue solution can be provided on the bearing curved surface 221 of the mounting bracket 220 so that the mirror 210 can be attached to the mounting bracket 220 through a colloid (the colloid is formed by curing the glue solution)).

[0064] In some embodiments, the first positioning hole 213 is provided on the side wall of the mirror 210, and the hole wall of the first positioning hole 213 is configured as a first arc wall. Opposite ends of the first arc wall along the arc direction of the first arc wall define a first opening K1, and the first opening K1 is respectively in communication with the first positioning hole 213 and the external environment.

[0065] Since opposite ends of the first arc wall along the arc direction of the first arc wall define a first opening K1, there can be a certain installation redundancy between the positioning member 121 and the corresponding first positioning hole 213, allowing the positioning member 121 to be adaptively passed through the corresponding first positioning hole 213 according to different dimensional tolerances. For example, there is a first tolerance between the outer peripheral wall of the positioning member 121 and the first arc wall (exemplarily, the first tolerance can be 0.2 mm, 0.3 mm, or 0.4 mm). When the positioning member 121 passes through the corresponding first positioning hole 213, the position of the positioning member 121 along the radial direction of the corresponding first positioning hole 213 can be conveniently adjusted by means of the first opening K1, that is, the distance between the positioning member 121 and the corresponding first positioning hole 213 along the radial direction of the first positioning hole 213 can be adjusted to be the first tolerance. Thus, the positioning member 121 can be adaptively passed through the corresponding first positioning hole 213 for setting.

[0066] In some embodiments, the second positioning hole 222 is provided on the side wall of the mounting bracket 220, and the hole wall of the second positioning hole 222 is configured as a second arc wall. Opposite ends of the second arc wall along the arc direction of the second arc wall define a second opening K2, and the second opening K2 is respectively in communication with the second positioning hole 222 and the external environment.

[0067] Since the opposite ends of the second arc-shaped wall along the arc direction of the second arc-shaped wall define a second opening K2, there can be a certain installation redundancy between the positioning member 121 and the corresponding second positioning hole 222, allowing the positioning member 121 to be adaptively passed through the corresponding second positioning hole 222 according to different dimensional tolerances. For example, there is a second tolerance between the outer peripheral wall of the positioning member 121 and the second arc-shaped wall (exemplarily, the second tolerance can be 0.2 mm, 0.3 mm or 0.4 mm). When the positioning member 121 passes through the corresponding second positioning hole 222, the position of the positioning member 121 along the radial direction of the corresponding second positioning hole 222 can be conveniently adjusted by means of the second opening K2, that is, the distance between the positioning member 121 and the corresponding second positioning hole 222 along the radial direction of the second positioning hole 222 can be adjusted to the second tolerance. In this way, the positioning member 121 can be adaptively passed through the corresponding second positioning hole 222 and set.

[0068] In some embodiments, the third positioning hole 132 is provided on the side wall of the pressure maintaining member 130, and the hole wall of the third positioning hole 132 is configured as a third arc-shaped wall. The opposite ends of the third arc-shaped wall along the arc direction of the third arc-shaped wall define a third opening K3, and the third opening K3 is respectively communicated with the third positioning hole 132 and the external environment.

[0069] Since the opposite ends of the third arc-shaped wall along the arc direction of the third arc-shaped wall define a third opening K3, there can be a certain installation redundancy between the positioning member 121 and the corresponding third positioning hole 132, allowing the positioning member 121 to be adaptively passed through the corresponding third positioning hole 132 according to different dimensional tolerances. For example, as Figure 6 shown, there is a third tolerance between the outer peripheral wall of the positioning member 121 and the third arc-shaped wall (exemplarily, the third tolerance D can be 0.2 mm, 0.3 mm or 0.4 mm). When the positioning member 121 passes through the corresponding third positioning hole 132, the position of the positioning member 121 along the radial direction of the corresponding third positioning hole 132 can be conveniently adjusted by means of the third opening K3, that is, the distance between the positioning member 121 and the corresponding third positioning hole 132 along the radial direction of the third positioning hole 132 can be adjusted to the third tolerance. In this way, the positioning member 121 can be adaptively passed through the corresponding third positioning hole 132 and set.

[0070] It can be that, as Figure 5 shown, the positioning member 121 is adaptively passed through the corresponding third positioning hole 132 and is in contact with the inner wall of the corresponding third positioning hole 132; or it can be that, as Figure 6As shown, the positioning member 121 is adaptively disposed through the corresponding third positioning hole 132, and there is a certain gap between the positioning member 121 and the inner wall of the corresponding third positioning hole 132, that is, there is a third tolerance between the positioning member 121 and the corresponding third positioning hole 132, indicating that there can be a certain installation redundancy between the positioning member 121 and the corresponding third positioning hole 132.

[0071] Similarly, it can be that the positioning member 121 is adaptively disposed through the corresponding second positioning hole 222 and is in contact with the inner wall of the corresponding second positioning hole 222; or it can be that the positioning member 121 is adaptively disposed through the corresponding second positioning hole 222, and there is a certain gap between the positioning member 121 and the inner wall of the corresponding second positioning hole 222, that is, there is a second tolerance between the positioning member 121 and the corresponding second positioning hole 222, indicating that there can be a certain installation redundancy between the positioning member 121 and the corresponding second positioning hole 222.

[0072] Similarly, it can be that the positioning member 121 is adaptively disposed through the corresponding first positioning hole 213 and is in contact with the inner wall of the corresponding first positioning hole 213; or it can be that the positioning member 121 is adaptively disposed through the corresponding first positioning hole 213, and there is a certain gap between the positioning member 121 and the inner wall of the corresponding first positioning hole 213, that is, there is a first tolerance between the positioning member 121 and the corresponding first positioning hole 213, indicating that there can be a certain installation redundancy between the positioning member 121 and the corresponding first positioning hole 213.

[0073] In some embodiments, as Figure 7 and Figure 8 shown, the positioning member 121 includes a support portion 1211 and a positioning portion 1212. The support portion 1211 is disposed on the base 110. Along the direction from the first curved surface 211 to the second curved surface 212, the positioning portion 1212 is connected to the side of the support portion 1211 away from the base 110. Among them, along the direction from the first curved surface 211 to the second curved surface 212, the positioning portion 1212 is successively and adaptively disposed through the corresponding second positioning hole 222, the corresponding first positioning hole 213, and the corresponding third positioning hole 132.

[0074] It can be that one end of the support portion 1211 away from the positioning portion 1212 is fixedly connected to the base 110; or it can be that one end of the support portion 1211 away from the positioning portion 1212 is detachably connected to the base 110 (for example, one end of the support portion 1211 away from the positioning portion 1212 is threadedly connected or clamped to the base 110), and no specific limitation is made here.

[0075] The alignment accuracy of the pressure maintaining member 130, the mirror 210, and the mounting bracket 220 can be improved by using the positioning portions 1212 of at least two positioning members 121. Furthermore, the mirror 210 can be better aligned and fitted to the mounting bracket 220, and thus the mirror 210 can be better utilized to prevent the problem of virtual image distortion, and further the quality of the image projected onto the windshield can be improved.

[0076] In some embodiments, in the direction from the first curved surface 211 to the second curved surface 212, the positioning portion 1212 is detachably connected to the side of the support portion 1211 away from the base 110.

[0077] It is convenient to replace or adjust the corresponding positioning portion 1212 according to the sizes of the corresponding second positioning holes 222, the corresponding first positioning holes 213, and the corresponding third positioning holes 132, which is beneficial to broaden the application range of the fitting jig 10.

[0078] In some embodiments, the positioning portion 1212 and the support portion 1211 are of an integrally formed structure.

[0079] In this way, the structural stability of the positioning member 121 can be improved, and it is also beneficial to better utilize the positioning member 121 to improve the alignment accuracy of the pressure maintaining member 130, the mirror 210, and the mounting bracket 220.

[0080] In some embodiments, the positioning portion 1212 has a first cross-section J in a direction perpendicular to the direction from the first curved surface 211 to the second curved surface 212, and the first cross-section J at least includes a circle, a bow shape, a square, or a semi-circle.

[0081] It may be that the first cross-section J is a circle, a bow shape, a square, or a semi-circle, where the square may include a rhombus or a square, etc. Or it may be that the first cross-section J includes a circle, a bow shape, a square, or a semi-circle.

[0082] Since the first cross-section J at least includes a circle, a bow shape, a square, or a semi-circle, in this way, the adaptability of the positioning portion 1212 to the corresponding second positioning holes 222, the corresponding first positioning holes 213, and the corresponding third positioning holes 132 can be improved, and further it is beneficial to better utilize the positioning member 121 to improve the alignment accuracy of the pressure maintaining member 130, the mirror 210, and the mounting bracket 220.

[0083] In some embodiments, please refer to Figure 8 and Figure 9, the first cross-section J corresponding to at least one positioning member 121 includes a connected first figure J1 and second figure J2. The first figure J1 is an arc shape or a semi-circular shape, so that the positioning portion 1212 can be respectively adapted to the corresponding second positioning hole 222, the corresponding first positioning hole 213, and the corresponding third positioning hole 132. The second figure J2 is used to indicate the circumferential position of the positioning member 121 relative to the corresponding second positioning hole 222, the corresponding first positioning hole 213, or the corresponding third positioning hole 132.

[0084] Exemplarily, the first cross-section J corresponding to one of the positioning members 121 of the positioning assembly 120 includes a connected first figure J1 and second figure J2, and the first cross-sections J corresponding to the remaining positioning members 121 are circular.

[0085] On the one hand, according to the first figure J1, the positioning member 121 can be adaptively arranged to pass through the corresponding second positioning hole 222, the corresponding first positioning hole 213, and the corresponding third positioning hole 132. On the other hand, according to the indication of the second figure J2, the circumferential position of the positioning member 121 relative to the corresponding second positioning hole 222, the corresponding first positioning hole 213, or the corresponding third positioning hole 132 can be adjusted. Furthermore, the positioning member 121 can be better adapted to be arranged to pass through the corresponding second positioning hole 222, the corresponding first positioning hole 213, and the corresponding third positioning hole 132.

[0086] In some embodiments, the second figure J2 is a triangle. The triangle has a first side that coincides with the chord of the first figure J1, and a first vertex J21 that is opposite to the first side. The first vertex J21 is provided on the side of the first side away from the first figure J1.

[0087] During the process of adjusting the circumferential position of the positioning member 121 relative to the corresponding second positioning hole 222, the corresponding first positioning hole 213, or the corresponding third positioning hole 132, the arc side of the first figure J1 corresponding to the positioning member 121 can be located within the corresponding second positioning hole 222, the corresponding first positioning hole 213, or the corresponding third positioning hole 132, and be respectively adapted to the corresponding second positioning hole 222, the corresponding first positioning hole 213, and the corresponding third positioning hole 132. And the first vertex J21 of the second figure J2 corresponding to the positioning member 121 can be located outside the corresponding second positioning hole 222, the corresponding first positioning hole 213, or the corresponding third positioning hole 132. In this way, the adaptability of the positioning member 121 to the corresponding second positioning hole 222, the corresponding first positioning hole 213, and the corresponding third positioning hole 132 can be improved. Furthermore, the alignment accuracy of the mirror 210 with respect to the mounting bracket 220 can be improved. Furthermore, the problem of virtual image distortion can be better solved by using the mirror 210. Furthermore, the quality of the image projected onto the windshield can be improved.

[0088] In some embodiments, the positioning member 121 further includes a clamping portion (not shown in the figure) clamped to the side of the supporting portion 1211 away from the base 110, and the clamping portion and the positioning portion 1212 are of an integrally formed structure.

[0089] In this way, while facilitating the disassembly, assembly or replacement of the positioning portion 1212, the structural stability of the positioning member 121 can also be improved.

The portion of the supporting surface 12111 where the positioning portion 1212 is not provided is used to carry the mounting bracket 220, the mirror 210 and the pressure maintaining member 130.

[0091] In this way, the portion of the supporting surface 12111 of the supporting portion 1211 where the positioning portion 1212 is not provided can be used to carry the mounting bracket 220, the mirror 210 and the pressure maintaining member 130, thereby improving the positioning reliability of the mounting bracket 220, the mirror 210 and the pressure maintaining member 130. Furthermore, the alignment accuracy of the mirror 210 with respect to the mounting bracket 220 can be improved, and thus the problem of virtual image distortion can be better solved by using the mirror 210, and the quality of the image projected onto the windshield can be improved.

[0092] In some embodiments, the positioning member 121 is used to align the central axes of the corresponding first positioning holes 213, the corresponding second positioning holes 222 and the corresponding third positioning holes 132.

[0095] The statement that "at least two first positioning holes 213 are symmetrically arranged on two first side walls 214" means that the number of first positioning holes 213 is an even number, and the even number of first positioning holes 213 are symmetrically arranged with reference to the symmetry axis of the two first side walls 214. It can be that one first positioning hole 213 is arranged on each of the two first side walls 214, and the two first positioning holes 213 are symmetrically arranged with reference to the symmetry axis of the two first side walls 214; it can also be that two first positioning holes 213 are arranged on each of the two first side walls 214, and the four first positioning holes 213 are symmetrically arranged with reference to the symmetry axis of the two first side walls 214; it can also be, as Figure 2 shown, three first positioning holes 213 are arranged on each of the two first side walls 214, and the six first positioning holes 213 are symmetrically arranged with reference to the symmetry axis of the two first side walls 214; and so on.

[0104] Optionally, the even number of the third positioning holes 132 are also symmetrically arranged with reference to the symmetry axis of the two sixth side walls 134.
