[0024] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other. This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] This disclosure provides a fixing fixture. For example... Figure 1 As shown, the fixing fixture includes a base 1 and a rotating member 2. The base 1 is used to place the middle frame 01 of the electronic device 0. The rotating member 2 is rotatably connected to the base 1 and is used to fix the display screen or back cover 02 of the electronic device 0. The rotating member 2 has at least two fixed positions, and the tilt angle of the rotating member 2 relative to the base 1 is different in different fixed positions.

[0027] Using the fixing fixture provided in this embodiment, the relative position of the base 1 and the rotating member 2 can be changed, that is, the relative position of the middle frame 01 and the back cover 02 can be changed. When the model of the electronic device 0 changes, resulting in the length of the FPC03 becoming shorter, the fixing position of the rotating member 2 can be changed, thereby enabling the connection of the FPC03 without redesigning the fixing fixture.

[0028] In related technologies, fixing fixtures are often used to fix the display screen and the middle frame, and to tilt the display screen and the middle frame relative to each other to facilitate the connection of the connecting wires between the display screen and the circuit board. The length of the connecting wires is often different from that of the FPC. Therefore, different fixing fixtures are often required when connecting the connecting wires to the FPC.

[0029] After adopting the fixing fixture provided in this embodiment, since the relative position of the base 1 and the rotating member 2 can be changed, even if the lengths of the FPC03 and the connecting line are different, the relative position of the base 1 and the rotating member 2 can be adjusted so that the connecting line and the FPC03 can be connected by a fixing fixture.

[0030] like Figure 3 As shown, in some embodiments, the fixing fixture further includes an adjustment component 4, which is connected to the rotating member 2 for adjusting the fixed position of the rotating member 2.

[0031] In this way, by setting a separate adjustment component 4 to adjust the fixed position of the rotating part 2, the rotation position of the rotating part 2 can be adjusted more conveniently than by using tools to adjust the position of the rotating part 2.

[0032] In some embodiments, the rotating member 2 can be directly hinged to the base 1.

[0033] In this way, the fixed position of the rotating part 2 can be changed more conveniently.

[0034] like Figure 3 As shown, in some other embodiments, the fixing fixture also includes a transmission assembly 3, which is connected to the rotating member 2 and the base 1 respectively.

[0035] If the rotating part 2 is directly hinged to the base 1, it may be difficult to fix the rotating part 2, which may cause the rotating part 2 to wobble. By using the transmission component 3, the fixed position of the rotating part 2 can be adjusted more conveniently, and the rotating part 2 can be fixed more conveniently, so as to reduce the possibility of the rotating part 2 wobble.

[0036] like Figure 3 As shown, in some embodiments, the transmission assembly 3 includes two connecting rods 31, which are arranged at intervals, and the two ends of each connecting rod 31 are respectively hinged to the rotating member 2 and the base 1.

[0037] Thus, since both ends of each of the two connecting rods 31 are rotatably connected to the rotating member 2 and the base 1 respectively, when the position of one connecting rod 31 is fixed, it is difficult for the other connecting rod 31 to rotate relative to the rotating member 2. Therefore, by fixing a single connecting rod 31, the position of the rotating member 2 can be fixed, thereby improving the stability of fixing the position of the rotating member 2. Furthermore, with this arrangement, the structure of the transmission assembly 3 is relatively simple, which reduces the structural complexity of the fixing fixture, thereby reducing the number of parts and assembly costs of the fixing fixture.

[0038] Combination Figure 2, Figure 3 As shown, in some embodiments, the base 1 includes a connected body 11 and a support structure 12. The body 11 is used to place the middle frame 01 of the electronic device 0, and the support structure 12 protrudes from the body 11 and is hinged to two connecting rods 31.

[0039] Thus, by setting the support structure 12, the rotating part 2 can be supported and positioned above the main body 11, thereby making it easier to adjust the position of the rotating part 2 to facilitate the connection of the FPC03.

[0040] like Figure 3 As shown, in some embodiments, the support structure 12 includes a first support portion 121, a second support portion 122, and a connecting rod 123. The first support portion 121 and the second support portion 122 are opposite to each other and connected to the body 11. The connecting rod 123 is located between the first support portion 121 and the second support portion 122. The two connecting rods 31 include a first connecting rod 311 and a second connecting rod 312. The first connecting rod 311 is sleeved on the connecting rod 123, and the two ends of the second connecting rod 312 are respectively passed through the first support portion 121 and the second support portion 122.

[0041] In this way, rotating the second link 312 can drive the rotating component 2 and the first link 311 to rotate, thereby adjusting the position of the rotating component 2. After the rotating component 2 reaches the target position, the first link 311 can be fixed to fix the position of the rotating component 2. Thus, a four-bar linkage mechanism can be formed, which allows for relatively convenient adjustment of the position of the rotating component 2.

[0042] Combination Figure 3 , Figure 4 As shown, in some embodiments, the fixing fixture further includes an adjustment assembly 4, which includes an adjustment member 41 and a limiting member 42. The adjustment member 41 is at least partially located on the side of the first support portion 121 away from the second support portion 122 and is connected to the second connecting rod 312. The outer wall of the adjustment member 41 has a first limiting portion 411. The limiting member 42 is movably connected to the first support portion 121 and has a second limiting portion 421 adapted to the first limiting portion 411. The second limiting portion 421 has a locking position that cooperates with the first limiting portion 411 and an unlocking position that avoids the first limiting portion 411.

[0043] Thus, when the second limiting part 421 is in the locked position, the position of the rotating part 2 can be fixed by the cooperation of the second limiting part 421 and the first limiting part 411. When it is necessary to adjust the fixed position of the rotating part 2, the second limiting part 421 can be moved to the unlocked position so that the first limiting part 411 and the second limiting part 421 can avoid each other. Then, the position of the second connecting rod 312 can be adjusted by the adjusting part 41, thereby adjusting the position of the rotating part 2. After the rotating part 2 moves to the target position, the second limiting part 421 can be returned to the locked position, thereby locking the adjusting part 41 and fixing the position of the rotating part 2.

[0044] Optionally, the adjusting member 41 is a knob, which can rotate around the second support part 122 to drive the second connecting rod 312 to rotate (the rotation angle range of the second connecting rod 312 is 0°~90°), thereby driving the rotating member 2 to rotate. The first limiting part 411 is toothed, and the limiting member 42 is a ratchet. The two form a ratchet mechanism, which automatically locks after the adjusting member 41 rotates to the target position to prevent displacement during operation.

[0045] This allows for relatively convenient adjustment of the position of the second link 312.

[0046] Optionally, the knob and the second linkage 312 are integrally formed, and this embodiment of the present disclosure does not limit this.

[0047] like Figure 4 As shown, in some embodiments, the limiting member 42 has a fixing part 422, a stretching part 423 and an elastic member 424, the stretching part 423 is connected to the second limiting part 421, and the elastic member 424 is located between the fixing part 422 and the second limiting part 421.

[0048] Thus, by pulling the tensioning part 423, the second limiting part 421 can be moved to the unlocked position. After the adjusting member 41 drives the rotating member 2 to move to the target position, the tensioning part 423 is released. Under the action of the elastic member 424, the second limiting part 421 can return to the locked position, thereby realizing the automatic locking of the adjusting member 41, and then realizing the locking of the second link 312, so as to prevent the second link 312 from shifting during the installation of the FPC03.

[0049] Alternatively, the elastic component can be a spring.

[0050] Combination Figure 2 , Figure 3As shown, in some embodiments, the rotating member 2 has a plurality of first hinge portions 21, which are arranged at intervals and are respectively hinged to the first connecting rod 311. Furthermore, the rotating member 2 has a plurality of second hinge portions 22, which are arranged at intervals and are respectively hinged to the second connecting rod 312.

[0051] In this way, the rotating part 2 can be hinged to the first connecting rod 311 and the second connecting rod 312 at different positions, thereby reducing the possibility of local tilting of the rotating part 2 and improving the stability of the movement of the rotating part 2.

[0052] Optionally, the first hinge portion 21 and the second hinge portion 22 are rod-shaped, with the end of the first connecting rod 311 sleeved on the first hinge portion 21 and the end of the second connecting rod 312 sleeved on the second hinge portion 22.

[0053] like Figure 2 As shown, in some embodiments, the rotating member 2 has at least one suction cup 23 for connection to the display screen or back cover 02 of the electronic device 0. A first hinge portion 21 is spaced apart from the suction cup 23, and a second hinge portion 22 is spaced apart from the suction cup 23.

[0054] In this way, the display screen or back cover 02 can be conveniently fixed using the suction cup 23. The first hinge part 21 is arranged at a distance from the suction cup 23, and the second hinge part 22 is arranged at a distance from the suction cup 23. This arrangement avoids interference between the first hinge part 21 and the second hinge part 22 and the operation of the suction cup 23, thus ensuring the stability of the suction cup 23.

[0055] Optionally, the suction cup 23 can be a vacuum suction cup 23, and the rotating part 2 has an air hole 26, which is connected to the vacuum suction cup 23. By evacuating or venting air, the display screen or back cover 02 can be tightened or loosened.

[0056] Combination Figure 1 , Figure 2 As shown, in some embodiments, the rotating member 2 has a first positioning part 24 and a second positioning part 25, which respectively abut against two adjacent edges of the display screen or the back cover 02.

[0057] In this way, the first positioning part 24 and the second positioning part 25 can be used to position the display screen or the back cover 02. When assembling electronic devices 0 of the same model, each display screen or each back cover 02 can be fixed in the corresponding position by adjusting the position of the rotating part 2 only once, which makes it more convenient to connect the FPC03 on each electronic device 0.

[0058] In some embodiments, the positions of the first positioning part 24 and the second positioning part 25 are adjustable.

[0059] Thus, when the model of the electronic device 0 changes, the positioning position of the display screen or the back cover 02 can be changed by adjusting the positions of the first positioning part 24 and the second positioning part 25, thereby improving the adaptability of the fixing fixture.

[0060] Combination Figure 1 , Figure 2 As shown, in some embodiments, the base 1 has a plurality of positioning posts 111, which are arranged at intervals to form a positioning space for placing the middle frame 01 of the electronic device 0.

[0061] In this way, the middle frame 01 of the electronic device 0 can be positioned by multiple positioning posts 111, so that the middle frame 01 of the electronic device 0 can be kept in a fixed position, thereby preventing the position of the middle frame 01 from shifting during the connection process of the FPC03.

[0062] The fixing fixture provided in this disclosure has at least the following advantages: 1. Easy to operate: The rotation angle of the second link can be controlled by the adjusting component, and the adjustment can be completed without tools.

[0063] 2. High versatility: It can adapt to various FPC lengths and back cover tilt angle requirements, reducing the inventory of fixing fixtures.

[0064] Based on the same concept, a production line for an electronic device 0 is provided, which includes the aforementioned fixing fixture.

[0065] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the embodiments disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
