Description

Technical Field

[0001] This application relates to the field of electronic device assembly and production technology, and in particular to an assembly fixture. Background Technology

[0002] Foldable electronic devices typically include a first housing, a second housing, and a hinge mechanism. The hinge mechanism is rotatably connected to both the first and second housings, thereby enabling the foldable electronic device to perform folding and unfolding actions.

[0003] In the assembly process of foldable electronic devices, the assembly of the first housing, the second housing, and the hinge mechanism is a very important step. At present, the industry basically uses the same assembly fixtures as for candybar electronic devices for assembling foldable electronic devices. After aligning the first housing and the second housing at 180°, the hinge mechanism is assembled between the first housing and the second housing.

[0004] However, due to factors such as the material dimensions between the first and second housings, the foldable electronic device assembled using the above-mentioned assembly fixture may exhibit defects such as over-expansion (i.e., the angle between the first and second housings is greater than 180°) or under-expansion (i.e., the angle between the first and second housings is less than 180°) when in the unfolded state. This makes it difficult to ensure the flatness of the foldable electronic device in the unfolded state and affects the production yield of the foldable electronic device. Utility Model Content

[0005] In view of this, this application provides an assembly fixture that can improve the flatness of foldable electronic devices in the unfolded state.

[0006] Specifically, the following technical solutions are included:

[0007] This application provides an assembly fixture, the assembly fixture comprising:

[0008] A first carrier, the first carrier having a first receiving groove, the first receiving groove being used to support a first housing;

[0009] A second carrier is connected to the first carrier, and the second carrier is provided with a second receiving slot for supporting the second housing.

[0010] Wherein, the included angle θ between the bottom surface of the first receiving groove and the bottom surface of the second receiving groove satisfies: θ < 180° or θ > 180°.

[0011] In the technical solution of this application, since the bottom surfaces of the first and second receiving grooves have an angle that is not 180°, the assembly fixture can absorb and correct the material size error between the first and second housings, ensuring the flatness of the foldable electronic device in the unfolded state. When the angle between the bottom surfaces of the first and second receiving grooves is less than 180°, the dimensions of the first and second housings that are at risk of over-expansion can be corrected during the assembly process. When the angle between the bottom surfaces of the first and second receiving grooves is greater than 180°, the dimensions of the first and second housings that are at risk of under-expansion can be corrected during the assembly process. Thus, the assembly fixture can improve the flatness of the foldable electronic device in the unfolded state and avoid the foldable electronic device from being over-expansion or under-expansion.

[0012] In one possible implementation, the assembly fixture further includes a first cover plate and a second cover plate;

[0013] The first cover plate covers the first receiving slot and is detachably connected to the first carrier, and the second cover plate covers the second receiving slot and is detachably connected to the second carrier.

[0014] In the technical solution of this application, by providing a detachable connection between the first cover plate and the first carrier, and a detachable connection between the second cover plate and the second carrier, it is convenient to assemble and disassemble the first cover plate and the second cover plate. When the first cover plate and the second cover plate are separated from the first carrier and the second carrier respectively, it is convenient to place the first housing and the second housing into the first receiving groove and the second receiving groove respectively; when the first cover plate and the second cover plate are connected to the first carrier and the second carrier respectively, it provides vertical pressing for the first housing and the second housing.

[0015] In one possible implementation, both the first cover plate and the second cover plate include a cover plate body, a pressing part, and an elastic element. The cover plate body and the pressing part are stacked, and the two ends of the elastic element are respectively connected to the cover plate body and the pressing part.

[0016] In the technical solution of this application, by setting the elastic element between the cover plate body and the pressing part, not only can the elastic force of the elastic element provide clamping force and buffering effect for the first housing and the second housing, but it can also make the force on the first housing and the second housing more uniform. Furthermore, the setting of the elastic element enables the first cover plate and the second cover plate to adapt to the first housing and the second housing of different heights, thereby improving the applicability and compatibility of the assembly fixture.

[0017] In one possible implementation, the assembly fixture further includes a first mounting portion and a second mounting portion, wherein the first mounting portion is connected to the side wall of the first carrier, and the second mounting portion is connected to the side wall of the second carrier.

[0018] The first cover plate is provided with a first buckle, and the second cover plate is provided with a second buckle. The first buckle is used to cooperate with the first mounting part for connection, and the second buckle is used to cooperate with the second mounting part for connection.

[0019] In the technical solution of this application, the first cover plate is detachably connected to the first carrier via a first snap-fit, and the second cover plate is detachably connected to the second carrier via a second snap-fit. The snap-fit ​​structure enables quick assembly and disassembly, improving the efficiency of assembly and disassembly between the first cover plate and the first carrier, as well as the efficiency of assembly and disassembly between the second cover plate and the second carrier. The first and second snap-fits respectively implement a side-locking design for the first and second cover plates, preventing displacement or shaking of the first and second cover plates when pressing against the first and second housings, ensuring stable pressure transmission from the first and second cover plates to the first and second housings respectively.

[0020] In one possible implementation, the first carrier is provided with a first positioning structure, the first cover plate is provided with a first mating structure, and the first positioning structure and the first mating structure are mated and connected.

[0021] The second carrier is provided with a second positioning structure, and the second cover plate is provided with a second mating structure. The second positioning structure and the second mating structure are mated and connected.

[0022] In the technical solution of this application, by setting a first positioning structure, a first mating structure, a second positioning structure and a second mating structure, the connection between the first carrier and the first cover plate and between the second carrier and the second cover plate is positioned, thereby improving the connection efficiency and ensuring that the first cover plate and the second cover plate are installed in the same position each time, thus eliminating the cumulative assembly error.

[0023] In one possible implementation, the assembly fixture further includes a first pressing block and a second pressing block;

[0024] The first end of the first pressure block is rotatably mounted on the first carrier so that the second end of the first pressure block can move above the first receiving slot, and the first pressure block is located at the end of the first carrier closer to the second carrier;

[0025] The first end of the second pressure block is rotatably mounted on the second carrier so that the second end of the second pressure block can move above the second receiving slot, and the second pressure block is located at the end of the second carrier near the first carrier.

[0026] In the technical solution of this application, the first pressure block and the second pressure block are used to press down the hinge mechanism so that the hinge mechanism does not lift up, and ensure that the hinge mechanism is reliably connected to the first housing and the second housing respectively.

[0027] In one possible implementation, the first end of the first pressure block is elastically connected to the first carrier, and the first pressure block is capable of telescopic movement along the height direction of the first carrier;

[0028] The first end of the second pressure block is elastically connected to the second carrier, and the second pressure block can extend and retract along the height direction of the second carrier.

[0029] In the technical solution of this application, the elastic connection between the first pressure block and the first carrier and the elastic connection between the second pressure block and the second carrier provide clamping force for the hinge mechanism, which is beneficial to improving the fixing effect of the first pressure block and the second pressure block on the hinge mechanism.

[0030] In one possible implementation, the first carrier has a mounting slot communicating with the first receiving slot, the mounting slot being located on the side of the first receiving slot away from the second receiving slot;

[0031] The assembly fixture further includes a side pusher, which is movably connected to the first carrier and at least part of the side pusher is disposed in the mounting groove. The side pusher is capable of moving along the arrangement direction of the mounting groove and the first receiving groove.

[0032] In the technical solution of this application, by setting a side pusher, the first housing in the first receiving groove can be pushed and squeezed in the direction of the second housing, thereby reducing the gap between the first housing and the second housing, which is conducive to the reliable assembly of the first housing, the second housing and the hinge mechanism.

[0033] In one possible implementation, the assembly fixture further includes a first base portion, a first support portion, a second base portion, and a second support portion;

[0034] The first base portion protrudes from the side wall of the first vehicle, and the first support portion is disposed on the first base portion. When the first cover plate is connected to the first vehicle, the top surface of the first support portion is further away from the top surface of the first vehicle than the top surface of the first cover plate.

[0035] The second base portion protrudes from the side wall of the second vehicle, and the second support portion is disposed on the second base portion. When the second cover plate is connected to the second vehicle, the top surface of the second support portion is further away from the top surface of the second vehicle than the top surface of the second cover plate.

[0036] In the technical solution of this application, the first support part and the second support part can provide support after the assembly fixture is rotated 180°, thereby improving the assembly stability of the hinge mechanism when the reverse screw is fastened.

[0037] In one possible implementation, the angle θ between the bottom surface of the first receiving groove and the bottom surface of the second receiving groove satisfies: θ < 170° or θ > 180°.

[0038] In the technical solution of this application, when θ < 170°, the assembly fixture is suitable for application scenarios with large material errors and strong material deformation capabilities, achieving more sufficient over-extension dimension correction and greatly reducing the over-extension risk of the first shell and the second shell.

[0039] In one possible implementation, the shape of the first receiving groove is adapted to fit the shape of the first housing, and the shape of the second receiving groove is adapted to fit the shape of the second housing.

[0040] In the technical solution of this application, by matching the shape of the first receiving groove with the shape of the first housing and the shape of the second receiving groove with the shape of the second housing, not only are the first housing and the second housing positioned, but the displacement and shaking of the first housing and the second housing during the assembly process are also reduced, thereby reducing the risk of amplification of assembly errors in foldable electronic devices.

Detailed Implementation

[0063] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0064] The directional terms used in the embodiments of this application, such as "up," "down," and "side," are generally based on the relative relationships shown in the figures. These directional terms are used merely to more clearly describe the relationships between structures, not to describe absolute directions. When the product is placed in different orientations, the orientation may change; for example, "up" and "down" may be interchanged.

[0065] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0066] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0067] like Figure 1 As shown, a foldable electronic device typically includes a first housing 100, a second housing 200, and a hinge mechanism 300. The hinge mechanism 300 is rotatably connected to the first housing 100 and the second housing 200, thereby enabling the first housing 100 and the second housing 200 to be folded or unfolded relative to each other, allowing the foldable electronic device to switch between a folded state and an unfolded state.

[0068] In the assembly process of foldable electronic devices, the assembly of the first housing 100, the second housing 200 and the hinge mechanism 300 is a very important step. At present, the industry basically uses the assembly fixture of the candybar electronic devices for the assembly of foldable electronic devices. After aligning the first housing 100 and the second housing 200 at 180°, the hinge mechanism 300 is assembled between the first housing 100 and the second housing 200.

[0069] However, due to factors such as the material dimensions between the first housing 100 and the second housing 200, the foldable electronic device assembled using the above-mentioned assembly fixture may exhibit defects such as over-expansion (i.e., the angle between the first housing 100 and the second housing 200 is greater than 180°) or under-expansion (i.e., the angle between the first housing 100 and the second housing 200 is less than 180°) when in the unfolded state. It is difficult to ensure the flatness of the foldable electronic device in the unfolded state, which affects the production yield of the foldable electronic device.

[0070] To address the aforementioned technical problems, this application provides an assembly fixture that can improve the flatness of foldable electronic devices in their unfolded state.

[0071] like Figure 2 As shown, the assembly fixture provided in this application includes a first carrier 1 and a second carrier 2. The assembly fixture is used at least for assembling a first housing 100, a second housing 200, and a hinge mechanism 300 of a foldable electronic device.

[0072] like Figure 3 As shown, the first carrier 1 is provided with a first receiving groove 11, which is used to support the first housing 100.

[0073] like Figure 4 As shown, the second carrier 2 is connected to the first carrier 1. The second carrier 2 is provided with a second receiving groove 21, which is used to support the second housing 200.

[0074] The included angle θ between the bottom surface of the first receiving groove 11 and the bottom surface of the second receiving groove 21 satisfies: θ < 180° or θ > 180°.

[0075] For example, the first receiving groove 11 and the second receiving groove 21 are interconnected, please refer to Figure 5 When assembling a foldable electronic device using an assembly fixture, the first housing 100 is placed in the first receiving groove 11, the second housing 200 is placed in the second receiving groove 21, and the hinge mechanism 300 is placed at the junction of the first housing 100 and the second housing 200. The hinge mechanism 300 is connected to the first housing 100 and the second housing 200 respectively using screws or other threaded fasteners.

[0076] The bottom surface of the first receiving groove 11 is the bearing surface of the first receiving groove 11 for supporting the first housing 100, and the bottom surface of the second receiving groove 21 is the bearing surface of the second receiving groove 21 for supporting the second housing 200. By setting the included angle θ between the bottom surface of the first receiving groove 11 and the bottom surface of the second receiving groove 21 to an angle other than 180°, θ can be used to actively offset or compensate for the dimensional error of the foldable electronic device, thereby actively correcting the dimensionality of the foldable electronic device and ensuring the flatness of the foldable electronic device in the unfolded state.

[0077] For example, for the first housing 100, the second housing 200, and the hinge mechanism 300, which have the risk of over-expansion due to differences in incoming material dimensions, if assembled using a conventional assembly fixture, the angle between the first housing 100 and the second housing 200 in the unfolded state after the foldable electronic device is assembled will be greater than 180°, resulting in over-expansion defects. However, by using the assembly fixture with θ < 180° provided in this application embodiment, the angle θ between the bottom surface of the first receiving groove 11 and the bottom surface of the second receiving groove 21 can be used to compensate for the material dimension differences between the first housing 100, the second housing 200, and the hinge mechanism 300. This causes the assembly gap between the first housing 100 and the second housing 200 to converge inward, thereby reducing the angle between the first housing 100 and the second housing 200 in the unfolded state of the assembled foldable electronic device and bringing it closer to 180°. This improves the flatness of the foldable electronic device in the unfolded state and reduces the risk of over-expansion.

[0078] For example, regarding the first housing 100, the second housing 200, and the hinge mechanism 300, which are at risk of under-expansion due to differences in incoming material dimensions, if assembled using a conventional assembly fixture, the angle between the first housing 100 and the second housing 200 in the unfolded state after the foldable electronic device is assembled will be less than 180°, resulting in under-expansion defects. However, by using the assembly fixture with θ > 180° provided in this application embodiment, the angle θ between the bottom surface of the first receiving groove 11 and the bottom surface of the second receiving groove 21 can compensate for the material dimension differences between the first housing 100, the second housing 200, and the hinge mechanism 300. This expands the assembly gap between the first housing 100 and the second housing 200 outwards, thereby increasing the angle between the first housing 100 and the second housing 200 in the unfolded state of the assembled foldable electronic device and bringing it closer to 180°. This improves the flatness of the foldable electronic device in the unfolded state and reduces the risk of under-expansion.

[0079] The assembly fixture provided in this application embodiment has an angle between the bottom surface of the first receiving groove 11 and the bottom surface of the second receiving groove 21, and the angle is not 180°. Therefore, the assembly fixture can absorb and correct the material size difference between the first housing 100 and the second housing 200, ensuring the flatness of the foldable electronic device in the unfolded state. When the angle between the bottom surface of the first receiving groove 11 and the bottom surface of the second receiving groove 21 is less than 180°, the fixture can correct the size of the first housing 100 and the second housing 200 that are at risk of over-expansion during the assembly process. When the angle between the bottom surface of the first receiving groove 11 and the bottom surface of the second receiving groove 21 is greater than 180°, the fixture can correct the size of the first housing 100 and the second housing 200 that are at risk of under-expansion during the assembly process. Thus, the assembly fixture can improve the flatness of the foldable electronic device in the unfolded state and avoid the foldable electronic device from being over-expanded or under-expanded.

[0080] In some embodiments, the shape of the first receiving groove 11 is adapted to fit the shape of the first housing 100, and the shape of the second receiving groove 21 is adapted to fit the shape of the second housing 200.

[0081] Please refer to Figures 3 to 5 The first receiving groove 11 and the second receiving groove 21 are designed to mimic the shape of the outer contour of the first housing 100, and the side wall of the second receiving groove 21 is designed to mimic the outer contour of the second housing 200.

[0082] In this embodiment, by matching the shape of the first receiving groove 11 with the shape of the first housing 100 and the shape of the second receiving groove 21 with the shape of the second housing 200, not only are the first housing 100 and the second housing 200 positioned, but the displacement and shaking of the first housing 100 and the second housing 200 during the assembly process are also reduced, thereby reducing the risk of amplified assembly errors in foldable electronic devices.

[0083] Optionally, the volume of the first receiving groove 11 is equal to or slightly larger than the volume of the first housing 100, and the volume of the second receiving groove 21 is equal to or slightly larger than the volume of the second housing 200. That is, the size of the first receiving groove 11 is adapted to the size of the first housing 100, and the size of the second receiving groove 21 is adapted to the size of the second housing 200.

[0084] This design improves the limiting effect on the first housing 100 and the second housing 200, further ensuring that the first housing 100 and the second housing 200 do not shift or wobble during assembly, thus enhancing the assembly stability of the foldable electronic device.

[0085] In some embodiments, such as Figure 6 As shown, the assembly fixture also includes a first cover plate 3 and a second cover plate 4.

[0086] The first cover plate 3 covers the first receiving groove 11 and is detachably connected to the first carrier 1, and the second cover plate 4 covers the second receiving groove 21 and is detachably connected to the second carrier 2.

[0087] The first cover plate 3 and the second cover plate 4 provide vertical pressing for the first housing 100 and the second housing 200, ensuring that the first housing 100 and the second housing 200 are in full contact with the bottom surfaces of the first receiving groove 11 and the second receiving groove 21, respectively, thus guaranteeing that the angle between the first housing 100 and the second housing 200 is consistent with θ. Simultaneously, the first cover plate 3 and the second cover plate 4 apply pressure to the first housing 100 and the second housing 200, respectively, preventing displacement of the first housing 100 and the second housing 200 or detachment from the assembly fixture.

[0088] The first cover plate 3 and the first carrier 1, and the second cover plate 4 and the second carrier 2 can be detachably connected by means of threaded fasteners, snap-fit ​​connections, etc.

[0089] By detachably connecting the first cover plate 3 to the first carrier 1 and the second cover plate 4 to the second carrier 2, it is convenient to assemble and disassemble the first cover plate 3 and the second cover plate 4. When the first cover plate 3 and the second cover plate 4 are separated from the first carrier 1 and the second carrier 2 respectively, it is convenient to place the first housing 100 and the second housing 200 into the first receiving groove 11 and the second receiving groove 21 respectively; when the first cover plate 3 and the second cover plate 4 are connected to the first carrier 1 and the second carrier 2 respectively, it provides vertical pressing for the first housing 100 and the second housing 200.

[0090] In some embodiments, please refer to Figure 7 The first cover plate 3 and the second cover plate 4 both include a cover plate body 31, a pressing part 32 and an elastic element 33. The cover plate body 31 and the pressing part 32 are stacked, and the two ends of the elastic element 33 are respectively connected to the cover plate body 31 and the pressing part 32.

[0091] The elastic element 33 can be a spring. The elastic element 33 has elastic deformation capability and can move in a stretching and contracting direction along its own length. One end of the elastic element 33 along its length is connected to the cover plate body 31, and the other end is connected to the pressing part 32. The pressing part 32 is located on the side of the cover plate body 31 near the first receiving groove 11 or the second receiving groove 21.

[0092] The number of elastic elements 33 can be one or more, for example Figure 7 As shown, there are four elastic elements 33 in the first cover plate 3.

[0093] In this embodiment, by placing the elastic element 33 between the cover plate body 31 and the pressing part 32, not only can the elastic force of the elastic element 33 provide clamping force and buffering effect for the first housing 100 and the second housing 200, but it can also make the force on the first housing 100 and the second housing 200 more uniform. Furthermore, the setting of the elastic element 33 enables the first cover plate 3 and the second cover plate 4 to adapt to the first housing 100 and the second housing 200 of different heights, thereby improving the applicability and compatibility of the assembly fixture.

[0094] In some embodiments, such as Figure 9 As shown, the assembly fixture also includes a first mounting part 51 and a second mounting part 52. The first mounting part 51 is connected to the side wall of the first carrier 1, and the second mounting part 52 is connected to the side wall of the second carrier 2. The first cover plate 3 is provided with a first buckle 34, and the second cover plate 4 is provided with a second buckle 41. The first buckle 34 is used to cooperate with the first mounting part 51, and the second buckle 41 is used to cooperate with the second mounting part 52.

[0095] The first mounting part 51 and the second mounting part 52 can be connected to the first carrier 1 and the second carrier 2 respectively by means of threaded fasteners, welding, etc., and this application does not make specific limitations.

[0096] The first cover plate 3 is detachably connected to the first carrier 1 via the first buckle 34, and the second cover plate 4 is detachably connected to the second carrier 2 via the second buckle 41. The buckle structure enables quick disassembly and assembly, improving the disassembly and assembly efficiency of the first cover plate 3 and the first carrier 1, as well as the disassembly and assembly efficiency of the second cover plate 4 and the second carrier 2.

[0097] For example, such as Figure 7 As shown, the first cover plate 3 is provided with two first latches 34, which are located on opposite sides of the first cover plate 3; Figure 8 As shown, the second cover plate 4 is provided with two second buckles 41, which are located on opposite sides of the second cover plate 4. The first buckle 34 and the second buckle 41 respectively realize the side locking design of the first cover plate 3 and the second cover plate 4, which can prevent the first cover plate 3 and the second cover plate 4 from shifting or shaking when pressing the first housing 100 and the second housing 200, and ensure that the first cover plate 3 and the second cover plate 4 stably transmit pressure to the first housing 100 and the second housing 200 respectively.

[0098] In some embodiments, the first carrier 1 is provided with a first positioning structure 12, and the first cover plate 3 is provided with a first mating structure 35, and the first positioning structure 12 and the first mating structure 35 are mated and connected.

[0099] The second carrier 2 is provided with a second positioning structure 22, and the second cover plate 4 is provided with a second mating structure 42. The second positioning structure 22 and the second mating structure 42 are mated and connected.

[0100] Optionally, one of the first positioning structure 12 and the first mating structure 35 is a protruding post structure, and the other is a hole structure. Through the post-hole mating, a quick positioning connection between the first carrier 1 and the first cover plate 3 is achieved. For example... Figure 3 and Figure 7 As shown, the first positioning structure 12 is a hole structure opened on the first carrier 1, and the first mating structure 35 is a protruding column structure protruding on the first cover plate 3.

[0101] Optionally, one of the second positioning structure 22 and the second mating structure 42 is a protruding post structure, and the other is a hole structure. Through the post-hole mating, the second carrier 2 and the second cover plate 4 can be quickly positioned and connected. For example... Figure 4 and Figure 8 As shown, the second positioning structure 22 is a hole structure opened on the second carrier 2, and the second mating structure 42 is a protruding column structure protruding on the second cover plate 4.

[0102] For example, there are multiple first positioning structures 12, multiple first mating structures 35, multiple second positioning structures 22 and multiple second mating structures 42. Multiple first positioning structures 12 and multiple first mating structures 35 are mated in a one-to-one correspondence, and multiple second positioning structures 22 and multiple second mating structures 42 are mated in a one-to-one correspondence, thereby improving the positioning accuracy between the first carrier 1 and the first cover plate 3 and between the second carrier 2 and the second cover plate 4.

[0103] In this embodiment, by setting the first positioning structure 12, the first mating structure 35, the second positioning structure 22 and the second mating structure 42, the connection between the first carrier 1 and the first cover plate 3 and between the second carrier 2 and the second cover plate 4 is positioned, thereby improving the connection efficiency and ensuring that the first cover plate 3 and the second cover plate 4 are installed in the same position each time, thus eliminating the cumulative assembly error.

[0104] In some embodiments, the assembly fixture further includes a first pressing block 61 and a second pressing block 62.

[0105] The first end of the first pressure block 61 is rotatably mounted on the first carrier 1 so that the second end of the first pressure block 61 can move above the first receiving groove 11. The first pressure block 61 is located at the end of the first carrier 1 near the second carrier 2.

[0106] The first end of the second pressure block 62 is rotatably mounted on the second carrier 2 so that the second end of the second pressure block 62 can move above the second receiving groove 21. The second pressure block 62 is located at the end of the second carrier 2 near the first carrier 1.

[0107] like Figure 5 As shown, the first pressing block 61 and the second pressing block 62 are used to press down the hinge mechanism 300, so that the hinge mechanism 300 does not lift up, and ensure that the hinge mechanism 300 is reliably connected to the first housing 100 and the second housing 200 respectively.

[0108] By placing the first pressure block 61 at one end of the first carrier 1 near the second carrier 2 and placing the second pressure block 62 at one end of the second carrier 2 near the first carrier 1, the first pressure block 61 and the second pressure block 62 are brought closer to the hinge mechanism 300 located between the first housing 100 and the second housing 200, which facilitates pressing the hinge mechanism 300.

[0109] The first pressing block 61 and the second pressing block 62 are rotatably mounted on the first carrier 1 and the second carrier 2, respectively, which improves the flexibility of the first pressing block 61 and the second pressing block 62 and avoids obstruction when placing the first housing 100 into the first receiving groove 11 or the second housing 200 into the second receiving groove 21.

[0110] Optionally, multiple first pressure blocks 61 and second pressure blocks 62 can be used to improve the clamping effect on the hinge mechanism 300. For example... Figure 5 As shown, there are two first pressing blocks 61 and two second pressing blocks 62. The two first pressing blocks 61 and the two second pressing blocks 62 press down on the four corner areas of the hinge mechanism 300 to ensure that the hinge mechanism 300 does not lift up.

[0111] In some embodiments, the first end of the first pressing block 61 is elastically connected to the first carrier 1, and the first pressing block 61 is capable of telescopic movement along the height direction of the first carrier 1. The first end of the second pressing block 62 is elastically connected to the second carrier 2, and the second pressing block 62 is capable of telescopic movement along the height direction of the second carrier 2.

[0112] For example, the first pressure block 61 and the second pressure block 62 are elastically connected to the first carrier 1 and the second carrier 2 respectively by elastic elements such as tension springs. The elastic elements can tighten between the first pressure block 61 and the first carrier 1, and between the second pressure block 62 and the second carrier 2.

[0113] Both the first pressure block 61 and the second pressure block 62 can extend and retract, making it convenient to adjust the height of the first pressure block 61 and the second pressure block 62, and to contact or separate from the hinge mechanism 300.

[0114] In this embodiment, the elastic connection between the first pressure block 61 and the first carrier 1 and the elastic connection between the second pressure block 62 and the second carrier 2 provide clamping force for the hinge mechanism 300, which helps to improve the fixing effect of the first pressure block 61 and the second pressure block 62 on the hinge mechanism 300.

[0115] In some embodiments, such as Figure 3 As shown, the first carrier 1 has a mounting groove 13 that communicates with the first receiving groove 11, and the mounting groove 13 is located on the side of the first receiving groove 11 away from the second receiving groove 21. Figure 1 As shown, the assembly fixture also includes a side pusher 7, which is movably connected to the first carrier 1 and at least part of the side pusher 7 is disposed in the mounting groove 13. The side pusher 7 can move along the arrangement direction of the mounting groove 13 and the first receiving groove 11.

[0116] like Figure 2 As shown, the side pusher 7 is located on the side of the first carrier 1 away from the second carrier 2. The side pusher 7 is capable of linear motion relative to the first carrier 1. Since the mounting groove 13 is connected to the first receiving groove 11, the side pusher 7 can contact the first housing 100 in the first receiving groove 11.

[0117] By setting the side pusher 7, the first housing 100 in the first receiving groove 11 can be pushed and squeezed in the direction of the second housing 200, thereby reducing the gap between the first housing 100 and the second housing 200, which is conducive to the reliable assembly of the first housing 100, the second housing 200 and the hinge mechanism 300.

[0118] Optionally, the side pusher 7 and the first carrier 1 are elastically connected by elastic elements such as springs, so that the side pusher 7 has the ability to reset. After the external force is removed after the side pusher 7 pushes the first housing 100, the side pusher 7 can return to its initial position under the action of elastic force.

[0119] In some embodiments, such as Figure 2 As shown, the assembly fixture also includes a first base portion 81, a first support portion 82, a second base portion 91, and a second support portion 92.

[0120] The first base portion 81 protrudes from the side wall of the first carrier 1, and the first support portion 82 is disposed on the first base portion 81. When the first cover plate 3 is connected to the first carrier 1, the top surface of the first support portion 82 is further away from the top surface of the first carrier 1 than the top surface of the first cover plate 3.

[0121] The second base portion 91 protrudes from the side wall of the second carrier 2, and the second support portion 92 is disposed on the second base portion 91. When the second cover plate 4 is connected to the second carrier 2, the top surface of the second support portion 92 is further away from the top surface of the second carrier 2 than the top surface of the second cover plate 4.

[0122] Understandably, the aforementioned "top surface" is... Figure 1 The upper surface as shown in the image.

[0123] In foldable electronic devices, the hinge mechanism 300 typically requires screw fastening on both the front and back sides to connect the hinge mechanism 300 to the first housing 100 / second housing 200. The first support portion 82 and the second support portion 92 provided in this embodiment can provide support after the assembly fixture is rotated 180°, improving the assembly stability of the hinge mechanism 300 when the screws are fastened on the back side.

[0124] By setting the top surface of the first support part 82 to be further away from the top surface of the first carrier 1 than the top surface of the first cover plate 3, and the top surface of the second support part 92 to be further away from the top surface of the second carrier 2 than the top surface of the second cover plate 4, the top of the first support part 82 is higher than the top of the first cover plate 3, and the top of the second support part 92 is higher than the top of the second cover plate 4. This ensures that after the assembly fixture is rotated 180°, the first support part 82 and the support part are in contact with the ground or other support surfaces and play a supporting role.

[0125] In some embodiments, the included angle θ between the bottom surface of the first receiving groove 11 and the bottom surface of the second receiving groove 21 satisfies: θ < 170° or θ > 180°.

[0126] With this setting, when θ < 170°, the assembly fixture can be applied to usage scenarios with large material errors and strong material deformation capabilities, achieving more sufficient over-extension dimension correction and greatly reducing the over-extension risk of the first shell 100 and the second shell 200.

[0127] As an example, the process of assembling a foldable electronic device using the assembly fixture provided in the embodiments of this application includes:

[0128] (1) Place the first housing 100 into the first receiving groove 11, place the second housing 200 into the second receiving groove 21, push the side pusher 7 to press the first housing 100 and the second housing 200 together to ensure that there is no gap between the first housing 100 and the second housing 200.

[0129] (2) Place the hinge mechanism 300 between the first housing 100 and the second housing 200 along the positioning holes in the first housing 100 and the second housing 200, and press the pivot floats on the sides of the first housing 100 and the second housing 200 respectively to ensure that the hinge mechanism 300 is assembled in place. The pivot floats are used to connect with the hinge mechanism 300.

[0130] (3) Rotate the first pressure block 61 and the second pressure block 62 to press down the hinge mechanism 300.

[0131] (4) Install the first cover plate 3 and the second cover plate 4 onto the first carrier 1 and the second carrier 2 respectively, so that the first buckle 34 is connected to the first mounting part 51 and the second buckle 41 is connected to the second mounting part 52.

[0132] (5) Tighten the screws on the hinge mechanism 300 from the front, then rotate the assembly fixture 180° and tighten the screws on the hinge mechanism 300 from the back.

[0133] (6) Then rotate the assembly fixture 180° so that the front of the assembly fixture is facing up, disconnect the connection between the first buckle 34 and the first mounting part 51 and the connection between the second buckle 41 and the second mounting part 52, remove the first cover plate 3 and the second cover plate 4, rotate the first pressure block 61 and the second pressure block 62, take out the assembled foldable electronic device, and visually inspect whether the unfolding angle is normal.

[0134] Understandably, the above "positive" refers to... Figure 2 or Figure 9 The upper side of the assembly fixture in the view shown, the aforementioned "reverse side" is Figure 2 or Figure 9 The lower side of the assembly fixture in the view shown.

[0135] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.
