The driving member 200 is used to drive the positioning member 100 to move, so that the positioning member 100 acts on the mounting body 300 from two different directions, so as to realize the positioning of the mounting body 300 and the main body 400. Exemplarily, the driving member 200 can be a mechanical arm, Figure 1 only the fixed block of the mechanical arm is shown in the figure, the main body 400 can be a mobile phone middle frame, a tablet computer middle frame, etc., and the mounting body 300 can be an inlay block or a bearing block accommodated in the inside of the main body 400, so as to support the electronic elements arranged on the main body 400.

[0029] For ease of description, Figure 2 and Figure 3 A three-dimensional coordinate system is added in each of Specifically, the X-axis direction is the first direction, the Z-axis direction is the second direction, and the Y-axis direction is the third direction. Among them, the X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other.

[0030] Please refer to Figure 2 , the positioning member 100 is used to position the mounting body 300 on the main body 400, and the positioning member 100 includes a fixed body 110, an extension body 120, a positioning body 130, and a pushing body 140. The fixed body 110 is used to connect the driving member 200 to move under the driving of the driving member 200, the extension body 120 is connected to the fixed body 110 and is arranged obliquely relative to the fixed body 110, the positioning body 130 is connected to the extension body 120 and is arranged extending along the X-axis direction, the pushing body 140 is connected to the positioning body 130 and is arranged extending along the Z-axis direction, the pushing body 140 and the positioning body 130 are arranged around the limiting groove 100a at the end away from the extension body 120, and the end of the positioning body 130 away from the extension body 120 is used to press the mounting body 300 to the main body 400 along the Z-axis direction, and the pushing body 140 is used to push the mounting body 300 to the main body 400 along the X-axis direction, so that part of the main body 400 and part of the mounting body 300 are located in the limiting groove 100a.

[0031] In the above positioning member 100, the fixed body 110 drives the pushing body 140 and the positioning body 130 to move synchronously under the driving of the driving member 200, so that the end of the positioning body 130 away from the extension body 120 presses the mounting body 300 to the main body 400 along the Z-axis direction, and the pushing body 140 pushes the mounting body 300 to the main body 400 along the X-axis direction, simplifying the positioning process and improving the positioning efficiency of the mounting body 300 and the main body 400.

[0032] It should be noted that in other embodiments, the included angle between the X-axis direction and the Z-axis direction can also be an acute angle, as long as the included angle between the positioning body 130 and the pushing body 140 is adapted to the included angle between the two faces of the mounting body 300 positioned by the positioning member.

[0033] Please refer to Figure 2 and Figure 3 In some embodiments, the fixed body 110 is provided with a connecting hole 110a, and the fixed body 110 is connected to the driving member 200 through the connecting hole 110a. Exemplarily, the connecting hole 110a can be a threaded hole and a blind hole, and the connecting hole 110a can be multiple to improve the stability of the connection between the fixed body 110 and the driving member 200.

[0034] Therefore, the connection between the fixed body 110 and the driving member 200 can be achieved through the connecting hole 110a, which is simple in structure and is conducive to reducing the use cost of the positioning member 100.

[0035] In this embodiment, the connecting holes 110a are two, and the two connecting holes 110a are arranged along the X-axis direction, and the fixing block of the mechanical arm can be detachably connected to the fixing body 110 through two bolts. In other embodiments, the connecting holes 110a can also be through holes, and the number of connecting holes 110a on the fixing body 110 can also be three or more than three.

[0036] In some embodiments, the thickness of the extension body 120 in the Z-axis direction gradually decreases in the direction in which the fixing body 110 points to the positioning body 130.

[0037] Therefore, through the above arrangement, the occupied space of the extension body 120 can be reduced, which is beneficial to the miniaturization of the positioning piece 100, so that the positioning piece 100 is suitable for narrow working space.

[0038] Please refer to Figure 2 and Figure 3 In some embodiments, the connecting surface of the extension body 120 and the fixing body 110 and the connecting surface of the extension body 120 and the positioning body 130 are both arc surfaces 100b.

[0039] Therefore, the arc surface 100b can reduce the collision intensity of external components on the positioning piece 100, which is beneficial to improve the service life of the positioning piece 100. In addition, the arc surface 100b can also improve the aesthetic degree of the positioning piece 100.

[0040] Please refer to Figure 2 In some embodiments, the positioning body 130 and the pushing body 140 are both two, the two positioning bodies 130 are arranged along the X-axis direction, and the two positioning bodies 130 are arranged along the Y-axis direction, the two pushing bodies 140 are arranged along the Z-axis direction, and the two pushing bodies 140 are arranged along the Y-axis direction.

[0041] Therefore, the two positioning bodies 130 and the two pushing bodies 140 can form two-point contact with the mounting body 300, which is beneficial to improve the stability of the force of the positioning piece 100 on the mounting body 300.

[0042] Please refer to Figure 2 In some embodiments, each positioning body 130 is provided with a chamfer 130a on the side facing the other positioning body 130, and the chamfer 130a is arranged at the end of the positioning body 130 away from the corresponding pushing body 140.

[0043] Therefore, the chamfer 130a can reduce the collision intensity of external components on the positioning body 130, which is beneficial to improve the service life of the positioning body 130. In addition, the chamfer 130a can also improve the aesthetic degree of the positioning body 130.

[0044] Please refer to Figure 2In some embodiments, the mounting body 300 is connected with the main body 400 through a locking body (not shown in the figure), which can be a bolt. Among the two positioning bodies 130, one is a first positioning body and the other is a second positioning body. The side of the first positioning body away from the second positioning body is provided with a position-avoiding groove 130b for passing through the locking body, and the position-avoiding groove 130b is located on the side of the corresponding pushing body 140 away from the extension body 120.

[0045] Therefore, the locking body can be guided to pass through the position-avoiding groove 130b, so as to lock the mounting body 300 and the main body 400, which is beneficial to improve the locking efficiency of the mounting body 300 and the main body 400.

[0046] Please refer to Figure 2 In some embodiments, the side of the second positioning body facing the first positioning body is provided with a movable groove 130c, and the movable groove 130c corresponds to the corresponding pushing body 140 in the Z-axis direction.

[0047] Therefore, the movable groove 130c can increase the operation space between the two positioning bodies 130 and reduce the weight of the positioning body 130.

[0048] In some embodiments, the fixing body 110, the extension body 120, the positioning body 130 and the pushing body 140 are of an integrated structure.

[0049] Therefore, the fixing body 110, the extension body 120, the positioning body 130 and the pushing body 140 of the integrated structure can simplify the machining process of the positioning member 100, which is beneficial to reduce the machining cost of the positioning member 100.

[0050] The working process of the above positioning mechanism 1000 is as follows:

[0051] Firstly, the main body 400 is placed on a bearing seat (not shown in the figure), and the mounting body 300 is placed on the main body 400;

[0052] Then, the driving member 200 drives the positioning member 100 to move, so that the end of the positioning body 130 away from the extension body 120 presses the mounting body 300 on the main body 400 along the Z-axis direction, and the pushing body 140 pushes the mounting body 300 on the main body 400 along the X-axis direction, until the locking position on the mounting body 300 corresponds to the locking position on the main body 400;

[0053] Finally, an external fixing mechanism drives the locking body to pass through the position-avoiding groove 130b to lock the mounting body 300 and the main body 400.

[0054] Therefore, the fixed body 110 in the positioning mechanism 1000 drives the driving member 200 to drive the pushing body 140 and the positioning body 130 to move synchronously, so that the positioning body 130 presses the mounting body 300 to the main body 400 along the Z-axis direction, and the pushing body 140 pushes the mounting body 300 to the main body 400 along the X-axis direction, which simplifies the positioning process and improves the positioning efficiency of the positioning mechanism 1000.
