[0031] The embodiment of the present application provides an assembly jig, which can prevent the circuit board from moving relative to the housing during the fixing process.
[0032] See also Figure 1 as well as Figure 2 , Figure 1 A schematic diagram of the first structure of the assembly jig provided in the embodiment of the present application, Figure 2 for Figure 1 An enlarged schematic diagram of local A.
[0033] The present application provides an assembly jig 100, which is applied to an electronic device 200. Specifically, the assembly jig 100 is applied to the assembly of the electronic device 200, and in particular refers to fixing the circuit board 210 of the electronic device 200 in a housing 220. The housing 220 is provided with a first receiving groove 221, and the circuit board 210 is disposed in the first receiving groove 221. The first receiving groove 221 may be a sinking groove, and the circuit board 210 is placed in the sinking groove. In some cases, the circuit board 210 may be divided into a plurality of sub-circuit boards, and the plurality of sub-circuit boards are connected in series or in parallel. In this case, the circuit board 210 placed in the first receiving groove 221 may be one or more of the sub-circuit boards.
[0034] Please continue reading Figure 2 , Figure 3 as well as Figure 4 , Figure 3 A second structural schematic diagram of an assembly jig and an electronic device provided in an embodiment of the present application, Figure 4 for Figure 3 Schematic diagram of the explosion.
[0035] The assembly fixture 100 includes a covering component 10 and a positioning member 20. The covering component 10 can clamp the circuit board 210 and the shell 220. The positioning member 20 can temporarily fix the relative position of the circuit board 210 and the shell 220, so that the fixing member 230 can fix the relative position of the circuit board 210 and the shell 220.
[0036] The cover assembly 10 includes a first cover body 11 and a second cover body 12. The first cover body 11 is rotatably connected to the second cover body 12. The first cover body 11 is provided with a second receiving groove 111, which faces the second cover body 12 and is used to accommodate the shell 220. The second cover body 12 is provided with a through hole 121.
[0037] Understandably, see Figure 1 as well as Figure 5 , Figure 5 The first cover 11 and the second cover 12 can be relatively rotated to open, such as Figure 1, or a closed state, such as Figure 5 When the first cover 11 and the second cover 12 are opened, the electronic device 200 is placed between the first cover 11 and the second cover 12, and the housing 220 of the electronic device 200 can be snapped into the second receiving groove 111 to fix the relative position of the electronic device 200 and the first cover 11. Figure 1 as well as Figure 2 The circuit board 210 is disposed in a first receiving groove 221 of the electronic device 200 , the notch of the first receiving groove 221 faces the second cover 12 , and the first receiving groove 221 can expose the circuit board 210 .
[0038] The positioning member 20 is connected to the second cover body 12 . Specifically, the positioning member 20 is disposed on a side of the second cover body 12 facing the first cover body 11 , and the positioning member 20 protrudes from a plane where the second cover body 12 is located.
[0039] See also Figure 6 as well as Figure 7 , Figure 6 A third structural schematic diagram of an assembly jig and an electronic device provided in an embodiment of the present application, Figure 7 for Figure 6 Section view along CC plane.
[0040] Under the premise that the electronic device 200 is placed between the first cover body 11 and the second cover body 12, when the first cover body 11 and the second cover body 12 are closed, the positioning member 20 is embedded between the groove wall of the first accommodating groove 221 and the circuit board 210 to limit the relative position of the circuit board 210 and the groove wall of the first accommodating groove 221, thereby limiting the relative position of the circuit board 210 and the shell 220.
[0041] See also Figure 5 The second cover 12 is provided with a through hole 121, and the through hole 121 is provided along the thickness direction of the second cover 12. When the first cover 11 and the second cover 12 are closed, the through hole 121 on the second cover 12 is located above the circuit board 210, that is, the projection of the through hole 121 on the first cover 11 is located within the projection of the circuit board 210 on the first cover 11, and then the fixing member 230 can be inserted into the through hole 121 and fix the housing 220 and the circuit board 210.
[0042] As described above, the assembly jig 100 provided in the embodiment of the present application is applicable to an electronic device 200, which includes a circuit board 210 and a housing 220. The housing 220 is provided with a first receiving groove 221, and the circuit board 210 is arranged in the first receiving groove 221. The assembly jig 100 includes a covering component 10 and a positioning member 20. When the first cover body 11 and the second cover body 12 of the covering component 10 are closed, the positioning member 20 is embedded between the groove wall of the first receiving groove 221 and the circuit board 210 to prevent the circuit board 210 from being displaced relative to the housing 220. The projection of the through hole 121 on the first cover body 11 is located at the projection of the circuit board 210 on the first cover body 11, so that the fixing member 230 can be inserted into the through hole 121 and then fix the housing 220 and the circuit board 210 to meet the electrical function requirements of the circuit board 210 and ensure consistency after assembly.
[0043] In some embodiments, please refer to Figure 2 , the circuit board 210 can be used to connect an external data line, and the housing 220 and the circuit board 210 together form an interface 2211 for charging or transmitting signals for the electronic device 200. For example, a USB interface and a Lightning interface, wherein the USB interface is further divided into a Type-A interface, a Type-B interface, a Type-C interface, and a Micro USB interface. In order to adapt to the connection of an external data line, the groove wall of the first accommodating groove 221 of the housing 220 is provided with an interface 2211, so that the data line can pass through the interface 2211 and be connected to the circuit board 210.
[0044] It is understandable that in the process of preparing the electronic device 200, the housing 220 and the circuit board 210 are often prepared first, and then the housing 220 and the circuit board 210 are assembled. However, the prior art does not use the assembly fixture 100 provided in the embodiment of the present application to fix the circuit board 210 on the housing 220, which causes the circuit board 210 to be displaced due to the influence of the torsional force when it is fixed on the housing 220, and often moves in a direction away from the interface 2211, affecting the distance and position accuracy between the circuit board 210 and the interface 2211, and thus poor contact is likely to occur during subsequent use.
[0045] In order to solve the problems existing in the prior art, please continue to refer to Figure 8 , Figure 8 for Figure 7An enlarged schematic diagram of part D. In the assembly jig 100 provided in the present application, the groove wall of the first accommodating groove 221 is provided with an interface 2211, and the interface 2211 is used to expose the circuit board 210. When the first cover body 11 and the second cover body 12 are closed, the positioning member 20 is arranged on the side of the circuit board 210 away from the interface 2211, and the positioning member 20 can resist the "retraction" phenomenon of the circuit board 210 during the fixing process, that is, resist the circuit board 210 from moving in a direction away from the interface 2211, so as to improve the reliability and assembly efficiency of the electronic device 200.
[0046] In some embodiments, see Fig. 9 , Fig. 9 for Figure 3 The free end of the positioning member 20 away from the second cover 12 has an inclined surface 21, which faces the circuit board 210, so that the positioning member 20 can be embedded between the groove wall of the first accommodating groove 221 and the circuit board 210 along the groove wall of the first accommodating groove 221.
[0047] In some embodiments, please refer to Figure 8 as well as Fig. 9 The assembly jig 100 further includes a guide sleeve 30, which can be inserted into the through hole 121 along the thickness direction of the second cover body 12. The end of the guide sleeve 30 close to the first cover body 11 extends toward the first cover body 11. The guide sleeve 30 is provided with a guide hole 31, which is configured to guide the fixing member 230 to fix the housing 220 and the circuit board 210. When the first cover body 11 and the second cover body 12 of the cover assembly 10 are closed, the guide sleeve 30 is arranged close to the circuit board 210 so as to accurately guide the fixing member 230 onto the circuit board 210.
[0048] Please continue reading Figure 8 The fixing member 230 may be a bolt. The circuit board 210 and the housing 220 have connected threaded holes, and the threaded holes are arranged corresponding to the through holes 121, or the threaded holes are arranged corresponding to the guide holes 31, so that the bolts pass through the through holes 121 or the guide holes 31 and are fixed on the circuit board 210 and the housing 220.
[0049] The through hole 121 is a countersunk hole, and the guide sleeve 30 is engaged with a step 1211 formed on the hole wall of the countersunk hole, which is beneficial for fixing the guide sleeve on the second cover body 12 .
[0050] Please continue reading Figure 7 The guide hole 31 includes a first hole segment 311 and a second hole segment 312. The first hole segment 311 and the second hole segment 312 are connected and coaxial. The first hole segment 311 is close to the first cover body 11. The first hole segment 311 is a straight hole, and the second hole segment 312 is a tapered hole. The diameter of the second hole segment 312 gradually decreases toward the first hole segment 311.
[0051] It is understandable that, in the process of fixing the circuit board 210 and the housing 220 by the fixing member 230, the fixing member 230 passes through the second hole section 312 and the first hole section 311 in sequence and is guided to fix the circuit board 210 and the housing 220. By setting the second hole section 312 as a tapered hole, the hole diameter is increased, which is conducive to improving the speed of the fixing member 230 entering the guide hole 31 and improving the assembly efficiency of the electronic device 200.
[0052] In some embodiments, see Fig.10 , Fig.10 A second structural schematic diagram of the assembly fixture provided in the embodiment of the present application. The first cover body 11 includes a fixed seat 112 and a plurality of relatively arranged limit platforms 113, the plurality of limit platforms 113 are connected to the fixed seat 112, each limit platform 113 is provided with a limit groove 1131, and the plurality of limit grooves 1131 form a second accommodating groove 111.
[0053] Since the electronic device 200 has a certain thickness and may have an uneven structure on its surface, the electronic device 200 may be suspended on the limiting platform 113 to avoid the uneven structure on the electronic device 200 and improve the stability of the support for the electronic device 200.
[0054] For example, in the electronic device 200 provided in the embodiment of the present application, the first receiving groove 221 protrudes from the surface of the housing 220. The assembly jig 100 has two limit platforms 113, which respectively support the two sides of the electronic device 200, so as to support the limit platforms 113 and avoid the first receiving groove 221, which is conducive to improving the stability of the electronic device 200 placed on the first cover 11.
[0055] Please continue to read Fig.10 The first cover 11 further includes a rotating shaft seat 114, which is connected to the fixed seat 112, and the thickness of the rotating shaft seat 114 is greater than or equal to the thickness of the limiting platform 113, and the second cover 12 is rotatably connected to the rotating shaft seat 114. Since the electronic device 200 has a certain thickness, the rotating shaft seat 114 is provided to facilitate the second cover 12 to smoothly rotate to a preset position, for example, the preset position is that the second cover 12 is approximately parallel to the housing 220, and then the positioning member 20 on the second cover 12 accurately acts on the electronic device 200.
[0056] Among them, see Figure 7 as well as Fig.10The assembly jig 100 further includes a limiting post 40, which is disposed on the first cover 11. When the first cover 11 and the second cover 12 are closed, the limiting post 40 abuts against the second cover 12, so that the first cover 11 and the second cover 12 are terminated at a preset position, for example, the preset position is that the second cover 12 is approximately parallel to the housing 220, so as to prevent the second cover 12 from gradually approaching the first cover 11 and causing the assembly jig 100 to squeeze and damage the electronic device 200. The limiting post 40 may be made of elastic material to play a certain buffering role.
[0057] In some embodiments, please refer to Fig.10 The first cover body 11 includes a fixing seat 112 and a support platform 115, the fixing seat 112 is connected to the support platform 115, the shell 220 is arranged on the support platform 115, and the support platform 115 can provide support for the shell 220. The assembly jig 100 also includes a buffer 50, and the buffer 50 is an elastic structure. The buffer 50 is connected to the second cover body 12. When the first cover body 11 and the second cover body 12 are closed, the buffer 50 abuts against the shell 220 and the buffer 50 and the support platform 115 jointly clamp the shell 220 to strengthen the relative position of the fixed shell 220 and the first cover body 11 to prevent the shell 220 from being displaced. The buffer 50 also has a certain buffering effect to prevent the second cover body 12 or the positioning member 20 from moving relative to the first cover body 11 and causing extrusion damage to the electronic device 200.
[0058] The assembly jig 100 provided in the embodiment of the present application is suitable for an electronic device 200, which includes a circuit board 210 and a housing 220. The housing 220 is provided with a first receiving groove 221, and the circuit board 210 is arranged in the first receiving groove 221. The assembly jig 100 includes a covering component 10 and a positioning member 20. When the first cover body 11 and the second cover body 12 of the covering component 10 are closed, the positioning member 20 is embedded between the groove wall of the first receiving groove 221 and the circuit board 210 to prevent the circuit board 210 from being displaced relative to the housing 220. The projection of the through hole 121 on the first cover body 11 is located at the projection of the circuit board 210 on the first cover body 11, so that the fixing member 230 can be inserted into the through hole 121 to fix the housing 220 and the circuit board 210, so as to meet the electrical function requirements of the circuit board 210 and the accuracy in the assembly process.
