Example Embodiment
[0078] Example one
[0079] Since the size of the TP lens is known, and the size of the front housing assembly used to install the TP lens on the mobile terminal is known, the centering position of the TP lens on the front housing assembly and the centering position of the TP lens can be accurately calculated The distance between its four periphery and the four periphery of the front shell assembly (hereinafter referred to as the preset gap value). This embodiment is implemented based on this preset gap value.
[0080] for figure 1 In order to accurately realize the TP lens centering of the mobile terminal shown, this embodiment proposes a TP lens centering device 300, such as image 3 with Figure 4 Shown, including:
[0081] The plastic body 301 includes a left side, a right side, an upper side, a right side, and a rear wall. The four sides enclose an accommodating space, and the accommodating space is related to the size and structure of the front shell assembly of the mobile ter...
Example Embodiment
[0090] Example two
[0091] In the first embodiment, on the plastic body 301 of the TP lens centering device 300, each side is provided with two limiting structures 302, so there are a total of 8 limiting structures 302 on the entire device 300, so that The precise positioning of the TP lens can be achieved in any direction.
[0092] However, in the actual operation process, it is only necessary to determine the positions of the adjacent two sides to accurately position the TP lens. Therefore, in this embodiment, under the premise of ensuring the realization of basic functions, in order to reduce the cost, only the plastic body 301 A limit structure 302 is respectively provided on two adjacent side edges, and the TP lens can be positioned by simply pressing the side edge of the TP lens against the corresponding limit structure 302 during operation.
[0093] In this embodiment, the structure of the TP lens centering device 300 is further simplified, and the cost is reduced.
Example Embodiment
[0094] Example three
[0095] In the first embodiment, the size of the plastic body 301 matches the size of the front shell assembly of the mobile terminal. The front shell assembly can be completely put into the plastic body 301, which is more convenient to operate. However, the size of the plastic body 301 is larger and the cost Higher.
[0096] In the third embodiment, in order to reduce the cost, the plastic body 301 adopts Image 6 The structure shown is only image 3 The upper part of the structure shown.
[0097] In the application, it is basically the same as the first embodiment: firstly, the plastic body 301 is sleeved on the upper part of the front housing assembly of the mobile terminal, and then the TP lens is positioned against the limiting structure 302.
[0098] The application of the third embodiment can reduce the production cost and realize the accurate centering of the TP lens.
