[0047] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0048] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0049] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0051] This embodiment provides an assembly tool for a hinge 10, which is used to Figure 1 The hinge 10 shown is assembled. Figure 1 As shown, the hinge 10 includes a connecting middle frame 11, a plurality of first swing arms 12, a plurality of second swing arms 13, a first support plate 14 and a second support plate 15. The first swing arm 12 and the second swing arm 13 are both rotatably connected to the connecting middle frame 11. The first swing arm 12 and the second swing arm 13 are respectively arranged on both sides of the connecting middle frame 11. The first support plate 14 is plugged into the plurality of first swing arms 12, and the second support plate 15 is plugged into the plurality of second swing arms 13.

[0052] The first support plate 14 (or the second support plate 15) may include only the first support plate 14 body, or may include a support plate body and at least one auxiliary plate. In this case, if there is a connection relationship between the support plate body and the auxiliary plate, the two can be connected and then set on the following assembly tool 20. In this case, the support plate body is connected to a part of the plurality of swing arms, and the auxiliary plate is connected to another part.

[0053] It should be noted that the above-mentioned "plug-in" does not limit the connection relationship between the first support plate 14 and the first swing arm 12 to a sliding connection. When the connection relationship between a first swing arm 12 and the first support plate 14 is a rotational connection, it is only necessary to reserve a first rotation hole on the first swing arm 12, reserve a corresponding second rotation hole on the first support plate 14, and set a plug-in slot that can reach the second rotation hole on the first support plate 14, so that when the first swing arm 12 is plugged into the first support plate 14 through the plug-in slot, the first rotation hole and the second rotation hole are aligned, and then only an axis needs to be passed through the first rotation hole and the second rotation hole. The connection relationship between the second support plate 15 and the second swing arm 13 is also not limited to a sliding connection, which will not be repeated.

[0054] The number of the first rotary arms 12 and the number of the second rotary arms 13 may be the same or different, and the rotation of the first rotary arms 12 and the second rotary arms 13 may be synchronous or asynchronous. Figure 1 In the figure, the number of first spiral arms 12 and the number of second spiral arms 13 are the same (both are six), and a plurality of first spiral arms 12 and a plurality of second spiral arms 13 are correspondingly arranged into a plurality of spiral arm pairs (six spiral arm pairs), and the first spiral arm 12 and the second spiral arm 13 in a spiral arm pair rotate synchronously.

[0055] Those skilled in the art should understand that the connecting middle frame 11 is also provided with a connecting shaft of the first swing arm 12 and the second swing arm 13 (if the rotation axis of a swing arm is a virtual axis, a corresponding rotation track is provided in the connecting middle frame 11), a damping mechanism, and a synchronization mechanism to be provided when the first swing arm 12 and the second swing arm 13 rotate synchronously, but the assembly of these structures is not realized by the assembly vehicle in this embodiment, so these structures are not described in detail in this embodiment.

[0056] Please refer to Figure 2-Figure 7 The assembly tool of the hinge 10 provided in this embodiment includes an assembly tool 20 and a pressing tool 30 .

[0057] Please refer to Figure 3 and Figure 4The assembly tool 20 includes an assembly base 21, a first pushing base 22, a second pushing base 23, a first sliding bar group 24, a second sliding bar group 25, a first pushing block 26 and a second pushing block 27; an alignment groove 211 is provided at the bottom of the assembly base 21, the first pushing base 22 and the second pushing base 23 are respectively arranged on both sides of the assembly base 21, the first sliding bar group 24 and the second sliding bar group 25 are respectively penetrated in the first pushing base 22 and the second pushing base 23, the first pushing block 26 and the second pushing block 27 are respectively slidably connected with the first sliding bar group 24 and the second sliding bar group 25; when the first support plate 14 is sleeved outside the first sliding bar group 24, the first support plate 14 presents a first preset inclination angle, and when the second support plate 15 is sleeved outside the second sliding bar group 25, the second support plate 15 presents a second preset inclination angle.

[0058] When the first swing arm 12 and the second swing arm 13 do not rotate synchronously, the first preset inclination angle and the second preset inclination angle may be the same or different. When the first swing arm 12 and the second swing arm 13 rotate synchronously, the first preset inclination angle and the second preset inclination angle are the same. It should be noted that the first preset inclination angle and the second preset inclination angle here are both defaulted to the angle between the first support plate 14 and the second support plate 15 and the horizontal plane when the assembly device 20 is placed horizontally; however, the first preset inclination angle and the second preset inclination angle are limited to emphasize the synchronization between each group of swing arms (a plurality of first swing arms 12 are a group, and a plurality of second swing arms 13 are another group) and between the swing arms and the support plates. The angle change caused by the change in the placement state of the group device or the angle change caused by the different selection of the reference plane does not affect the implementation of the solution in this embodiment.

[0059] In order to facilitate the setting of the first preset inclination angle and the second preset inclination angle and ensure the accuracy of both, as Figure 3 and Figure 4 As shown, the two sides of the assembly base 21 may be provided with a first inclined surface 21a with a first preset inclination angle and a second inclined surface 21b with a second preset inclination angle, and the first pushing base 22 and the second pushing base 23 are respectively provided on the first inclined surface 21a and the second inclined surface 21b. At this time, the connection between the first pushing base 22 and the assembly base 21, the connection between the first sliding rod group and the first pushing base 22, the connection between the second pushing base 23 and the assembly base 21, and the connection between the second sliding rod group and the second pushing base 23 do not need to consider the inclination angle, which simplifies the structure, reduces the number of variables that may cause errors, and improves accuracy.

[0060] The first pushing base 22 and the second pushing base 23 can be screwed to the assembly base 21. In order to improve the installation convenience and accuracy between the first pushing base 22, the second pushing base 23 and the assembly base 21, as shown in FIG. Figure 3 and Figure 4As shown, the first inclined surface 21a and the second inclined surface 21b may be provided with a first limiting slide groove 212 and a second limiting slide groove 213, respectively, and the first pushing base 22 and the second pushing base 23 may be provided with a first limiting slider 221 and a second limiting slider 231, respectively. When the first limiting slider 221 is placed in the first limiting slide groove 212, the first pushing base 22 is accurately hooked at a preset position on the assembly base 21, and then screwed and fixed; when the second limiting slider 231 is placed in the second limiting slide groove 213, the second pushing base 23 is accurately hooked at a preset position on the assembly base 21, and then screwed and fixed. At this time, based on the fact that the positions of the first pushing base 22 and the second pushing base 23 have been accurately defined, there is no need to make a precise definition of the size of the connecting hole in the threaded connection; specifically, if the first pushing base 22 is provided with a first connecting hole 222, and the corresponding second connecting hole is provided on the assembling base 21, then in order to facilitate assembly, the first connecting hole 222 can be set as a waist-shaped hole, and the second connecting hole can be a threaded hole; the threaded connection connecting holes between the second pushing base 23 and the assembling base 21 are similar and will not be repeated.

[0061] Please refer to Figure 5 and Figure 6 The pressing tool 30 includes a first pressing seat 31 and a second pressing seat 32, and there is an accommodating space connected to the middle frame 11 therebetween. When the second pressing seat 32 is fixedly connected to the first pressing seat 31, the plurality of first swing arms 12 are fixed at a first preset inclination angle, and the plurality of second swing arms 13 are fixed at a second preset inclination angle.

[0062] Please refer to Figure 5 and Figure 6 The first pressing seat 31 is provided with a first pressing block 311 corresponding to the first side of the first swing arm 12 and the second swing arm 13, and the second pressing seat 32 is provided with a second pressing block 321 corresponding to the first side of the first swing arm 12 and the second swing arm 13. When the second pressing seat 32 is fixedly connected to the first pressing seat 31, the second pressing block 321 and the corresponding first pressing block 311 are aligned and pressed against the two sides of a swing arm so that they are at a preset inclination angle.

[0063] The fixed connection between the first pressure fixing seat 31 and the second pressure fixing seat 32 is a detachable fixed connection, such as a snap-fit ​​fixed connection or a locking fixed connection.

[0064] Please refer to Figure 5 and Figure 6In order to improve the convenience of fixed connection and disassembly between the first pressure fixing seat 31 and the second pressure fixing seat 32, eccentric locking members 33 can be provided at both ends of the first pressure fixing seat 31, and the eccentric locking members 33 include an anchor rod 331 and an eccentric locking pressure rod 332. One end of the anchor rod 331 is provided on the first pressure fixing seat 31, and the other end is rotatably connected to the eccentric locking pressure rod 332; an anchor groove 322 corresponding to the anchor rod 331 is provided on the second pressure fixing seat 32, the anchor rod 331 is penetrated into the anchor groove 322, and when the eccentric locking pressure rod 332 rotates to press against the end face of the second pressure fixing seat 32 away from the first pressure fixing seat 31, the second pressure fixing seat 32 is locked and fixed on the first pressure fixing seat 31.

[0065] Please refer to Figure 6 and Figure 7 The eccentric locking pressure rod 332 includes an eccentric wheel 332a and a pressure rod 332b. The eccentric wheel 332a is rotatably connected to the anchor rod 331, and the pressure rod 332b is fixedly connected to the eccentric wheel 332a. In order to improve the stability of the fixed connection between the first pressure fixing seat 31 and the second pressure fixing seat 32, a locking groove 323 corresponding to the cam end of the eccentric wheel 332a can be provided on the second pressure fixing seat 32. When the eccentric wheel 332a rotates until the cam end is embedded in the locking groove 323, the second pressure fixing seat 32 is locked and fixed on the first pressure fixing seat 31.

[0066] In order to further improve the stability of the first pressing seat 31 and the second pressing seat 32 when they are fixedly connected, and to improve the self-locking property of the eccentric locking rod 332, as shown in FIG. Figure 7 As shown, a cutting surface 332c can also be set on the eccentric wheel 332a to form a convex point 332d at the cam end of the eccentric wheel 332a, and a protruding surface 323a is set in the locking groove 323 to form a concave point 323b at the bottom of the locking groove 323. When the eccentric wheel 332a rotates until the convex point 332d is embedded in the concave point 323b, the second pressure fixing seat 32 is locked and fixed on the first pressure fixing seat 31.

[0067] In order to improve the alignment accuracy when the first press-fixing seat 31 and the second press-fixing seat 32 are connected, as shown in FIG. Figure 5 As shown, at least one first alignment rod 312 may be provided on the first pressure fixing seat 31 , and a first alignment hole 324 corresponding to the alignment rod may be provided on the second pressure fixing seat 32 .

[0068] In order to improve the alignment accuracy of the first press-fit seat 31 and the assembly tool 20 during alignment and connection, as shown in FIG. Figure 3 and Figure 4 As shown, at least one second alignment rod 214 may be disposed at the bottom of the alignment groove 211 , and a second alignment hole corresponding to the second alignment rod 214 may be disposed at the bottom of the first press-fit seat 31 .

[0069] In the assembly tool of this embodiment, when the pressing tool 30 (specifically the first pressing seat 31) is aligned in the alignment groove 211, the sliding rods in the first sliding rod group 24 are connected one by one with the first swing arm 12, and the first support plate 14 can slide from the first sliding rod group 24 to the first swing arm 12 under the push of the first pushing block 26, and the sliding rods in the second sliding rod group 25 are connected one by one with the second swing arm 13, and the second support plate 15 can slide from the second sliding rod group 25 to the second swing arm 13 under the push of the second pushing block 27; thereafter, when the first pushing block 26 and the second pushing block 27 fall back, the pressing tool 30 can be removed from the self-assembly tool 20 to obtain the assembled hinge 10. In actual application, there may be a situation where the extension length of a certain swing arm is less than the width of the support plate, that is, at this time the support plate is completely pushed onto the corresponding swing arm, but the corresponding slide bar is still partially located in the support plate. Therefore, in order to prevent the slide bar located in the support plate from affecting the assembled hinge 10 when the clamp 30 is removed from the self-assembly tool 20, a first slide bar group 24 inserted in the first pushing base 22 and a second slide bar group 25 inserted in the second pushing base 23 can be provided. Both can be pulled under the action of external force, thereby causing the slide bars therein to retreat until they are separated from the support plate; of course, in order not to affect the functional realization of the entire assembly tool, the first slide bar group 24 and the second slide bar group 25 are clamped by other devices and will not move except for the retreat situation after the assembly is completed.

[0070] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present utility model.
