[0031] The following is combined with Figures 1-6 The electronic device assembly fixture provided by the present invention will be described in detail through specific embodiments and application scenarios.

[0032] In some embodiments, such as Figures 1 to 3As shown, this embodiment provides an electronic device assembly fixture, including an upper mold 1, a lower mold 2, a mounting base 3, and an elastic element 4. The mounting base 3 is connected to the upper mold 1, and the distance between the two is adjustable. The elastic element 4 is located between the mounting base 3 and the upper mold 1. The mounting base 3 and the lower mold 2 are detachably connected to form a receiving cavity between the upper mold 1 and the lower mold 2 for placing the housing 100 and battery cover 200 of the electronic device.

[0033] Specifically, such as Figure 2 and Figure 3 As shown, the lower mold 2 and the upper mold 1 are joined to form a receiving cavity. The battery cover 200 and the housing 100 are pre-assembled by applying adhesive or backing adhesive and then placed into the receiving cavity. The battery cover 200 is located on the side of the housing 100 facing the upper mold 1. The mounting base 3 and the lower mold 2 are arranged opposite each other. The upper mold 1 is located between the mounting base 3 and the lower mold 2. Optionally, both the mounting base 3 and the lower mold 2 are provided with screw holes, and the two are fixed together by fastening bolts. After clamping, the mounting base 3 and the lower mold 2 are separated by removing the fastening bolts. Alternatively, the mounting base 3 and the lower mold 2 are fastened together by a snap fastener and a snap fastener seat.

[0034] like Figure 2 As shown, the elastic element 4 is sandwiched between the mounting base 3 and the upper mold 1. The elastic element 4 can be a spring. There can be one or more elastic elements 4. When there is only one elastic element 4, one end of the elastic element 4 abuts against the mounting base 3, and the other end abuts against the upper mold 1. When there are multiple elastic elements 4, some elastic elements 4 are fitted onto the adjusting bolt 5, and other elastic elements 4 abut against the mounting base 3 and the upper mold 1. Alternatively, multiple elastic elements 4 abut against the mounting base 3 and the upper mold 1.

[0035] During assembly, the upper mold 1 is aligned with one side of the electronic device, and then the mounting base 3 is pressed down further to make the mounting base 3 and the lower mold 2 snap together. During this process, the mounting base 3 continues to move down and compresses the elastic element 4, thereby using the rebound force of the elastic element 4 to press the upper mold 1 tightly against the electronic device, thus maintaining a constant force between the housing 100 and the battery cover 200 on the electronic device.

[0036] The distance between the mounting base 3 and the upper mold 1 is adjusted by adjusting bolt 5. In one embodiment, the adjusting bolt 5 is a screw with a nut. The mounting base 3 has a connecting hole, one end of the adjusting bolt 5 is fixed to the upper mold 1, and the other end of the adjusting bolt 5 passes through the connecting hole and is connected to the nut. The mounting base 3 can move up and down along the adjusting bolt 5. Rotating the nut of the adjusting bolt 5 adjusts the distance between the mounting base 3 and the upper mold 1. In another embodiment, the mounting base 3 has a connecting hole, and the upper mold 1 has a threaded hole. One end of the adjusting bolt 5 has a limiting element, and the other end passes through the connecting hole and is threaded into the threaded hole. The mounting base 3 can move up and down along the adjusting bolt 5. Rotating the adjusting bolt 5 adjusts the depth to which the screw is screwed into the threaded hole, thereby adjusting the distance between the mounting base 3 and the upper mold 1.

[0037] By adjusting the position of the adjusting bolt 5, the distance between the mounting base 3 and the upper mold 1 can be changed, thereby adjusting the compression degree of the elastic element 4 after the mounting base 3 and the lower mold 2 are engaged, adjusting the clamping force of the upper mold 1 on the battery cover 200, and adapting to the assembly precision requirements of different electronic devices.

[0038] When assembling the battery cover 200, adjust the adjusting bolt 5 beforehand to ensure that the elastic force of the elastic element 4 meets the requirements after the mounting base 3 and the lower mold 2 are engaged. Then, place the pre-assembled housing 100 and battery cover 200 into the lower mold 2, with the upper mold 1 aligned with one side of the electronic device. Push the mounting base 3 down to engage with the lower mold 2. After the upper mold 1 maintains pressure on the battery cover 200 for a preset time, disassemble and separate the mounting base 3 and the lower mold 2, and remove the housing 100 and battery cover 200 to complete the assembly.

[0039] This embodiment provides an electronic device assembly fixture. After the mounting base 3 and the lower mold 2 are engaged, the elastic element 4 is compressed, which in turn pushes the upper mold 1 to continuously apply pressure to the housing 100 and battery cover 200 of the electronic device placed in the accommodating cavity. This maintains a stable pressing force between the battery cover 200 and the housing 100, thereby ensuring that the bonding strength of the battery cover 200 meets the requirements, guaranteeing the assembly effect between the battery cover 200 and the housing 100, and thus ensuring the overall assembly accuracy of the electronic device.

[0040] In some embodiments, such as Figure 4 As shown, the lower mold 2 includes a lower template 21 and a base 22, with the lower template 21 and base 22 fixedly connected. The lower template 21 is provided with a groove 211. Figure 3 As shown, the upper mold 1 includes an upper template 11 and a mounting plate 12. The upper template 11 is fixed to the mounting plate 12, and the elastic element 4 is located between the mounting plate 12 and the mounting base 3. The upper template 11 has a contoured surface 111. When the upper template 11 covers the groove 211, the contoured surface 111 and the groove 211 cooperate to form a receiving cavity.

[0041] Specifically, the lower template 21 and the base 22 can be an integral structure, or they can be fixedly connected by bolts or other fasteners. Similarly, the upper template 11 and the mounting plate 12 can be an integral structure, or they can be fixedly connected by fasteners.

[0042] The groove shape of the groove 211 is adapted to the housing 100 of the electronic device to facilitate the placement of the housing 100. For example, when the housing 100 of the electronic device is elongated, the groove 211 is elongated. In one embodiment, the groove wall of the groove 211 limits the housing 100, ensuring that the housing 100 will not shift during assembly. In another embodiment, such as... Figure 3 and Figure 4 As shown, the circumferential walls of the tank 211 are provided with positioning blocks 2111. When the housing of the electronic device is placed in the tank 211, the positioning blocks 2111 on the opposite side of the tank wall constrain the degree of freedom of movement of the housing 100 in the tank 211, and the gap between the tank wall of the tank 211 and the housing 100 is used to facilitate the removal of the housing 100 from the tank 211.

[0043] like Figure 3 As shown, the mounting plate 12 is a plate body, and one side of the upper template 11 has a contoured surface, while the other side is attached to and fixedly connected to the mounting plate 12. The elastic element 4 is located between the mounting base 3 and the mounting plate 12. During assembly, the upper template 11 can be locked to the mounting plate 12 using fastening screws, so that the mounting plate 12 provides support for the upper template 11.

[0044] like Figure 3 As shown, the upper mold 11 has a contoured surface 111 on the side away from the mounting plate 12. The shape of the contoured surface 111 is adapted to the shape of the side where the battery cover 200 of the electronic device is located. When the upper mold 1 closes to the groove of the groove 211, the contoured surface 111 and the groove wall of the groove 211 form a receiving cavity to accommodate the pre-assembled structure of the housing 100 and the battery cover 200. By providing the contoured surface 111 on the upper mold 1, the upper mold 1 can better fit with the top surface of the battery cover 200, further ensuring the assembly effect of the electronic device assembly fixture on the battery cover 200 and the housing 100. For example, when the top surface of the battery cover 200 is a curved surface with one end slightly curved upwards, the shape of the contoured surface 111 is also a curved surface with one end curved upwards. The shape of the contoured surface 111 can be reasonably set according to the different shapes of the top surface of the battery cover 200, and there is no specific limitation thereto.

[0045] In some embodiments, such as Figure 4 and Figure 5As shown, one of the base 22 and the mounting base 3 is fixedly mounted with the first buckle 221, while the other is rotatably mounted with the second buckle 31. A first locking head 2211 protrudes from one side of the first buckle 221, and a second locking head 311 protrudes from one side of the second buckle 31. The first locking head 2211 and the second locking head 311 overlap to constrain the vertical position of the upper mold 1 and the lower mold 2.

[0046] Specifically, such as Figure 4 As shown, the first buckle 221 is fixedly installed on the base 22 by screws or is integrated with the base 22.

[0047] In use, after the second latch 311 abuts against the first latch 2211, it continues to push down, and the second latch 31 rotates to provide clearance space so that the second latch 311 passes over the first latch 2211 and is firmly connected together, thereby realizing a stable connection between the mounting base 3 and the base 22, constraining the vertical position of the mounting base 3 and the base 22, preventing the upper mold 1 and the lower mold 2 from vertically shifting during the assembly process, and ensuring the assembly effect of the electronic equipment.

[0048] Optionally, both the first locking head 2211 and the second locking head 311 are provided with guide slopes. When the second locking head 311 and the first locking head 2211 initially abut, their guide slopes face each other. At this time, if the mounting base 3 is pushed down further, a compression will occur between the second locking head 311 and the first locking head 2211, causing the second latch 31 to rotate. The guide slopes then guide the second locking head 311 past the first locking head 2211.

[0049] The number of first locking heads 2211 can be set to multiple. For example, two first locking heads 2211 are arranged in parallel on the first buckle 221. The number of second locking heads 311 is consistent with that of the first locking heads 2211. Multiple first locking heads 2211 and multiple second locking heads 311 are connected together in a one-to-one correspondence to increase the vertical constraint of the mounting base 3 and the base 22 on the upper mold 1 and the lower mold 2.

[0050] Of course, the first buckle 221 can also be fixed to the mounting base 3. The second buckle 31 can be rotated and installed on the base 22, which can also achieve vertical constraint of the first buckle head 2211 and the second buckle head 311 on the upper mold 1 and the lower mold 2.

[0051] In one specific embodiment, such as Figure 5 As shown, the mounting base 3 is fixedly connected to the fixing block 6. The second latch 31 is rotatably mounted on the fixing block 6. A spring-loaded element 7 is installed between the second latch 31 and the fixing block 6. The first latch head 2211 is located on the outer side of the first latch 221. The second latch head 311 is located on the inner side of the second latch 31. The outer side of the first latch 221 refers to the side of the first latch 221 away from the receiving cavity, and the inner side of the second latch 31 refers to the side of the second latch 31 closer to the receiving cavity.

[0052] Specifically, the fixing block 6 can be locked to the mounting base 3 using screws or other fasteners, or the fixing block 6 and the mounting base 3 can be an integral structure. Optionally, the second snap-fit ​​31 has a connecting hole. The rotating shaft passes through the connecting hole to fix the second snap-fit ​​31 to the rotating shaft, and both ends of the rotating shaft are rotatably mounted to the fixing block 6 via bearings, thereby realizing the rotatable connection between the second snap-fit ​​31 and the mounting base 3. Alternatively, the fixing block has a mounting groove, and both ends of the rotating shaft are fixedly connected to the opposite sides of the mounting groove, and the second snap-fit ​​31 can be rotatably sleeved on the rotating shaft. Of course, the second snap-fit ​​31 can also be connected by other rotatable engagement methods.

[0053] A spring-loaded member 7 is sandwiched between the side of the second latch 31 away from the second latch head 311 and the mounting base 3. Optionally, the spring-loaded member 7 can be a torsion spring or a regular spring. During assembly, after the first latch 221 and the second latch 31 abut against each other, the mounting base 3 is pushed downwards. The second latch 31 rotates under the abutment of the first latch 221, squeezing the spring-loaded member 7 and causing the second latch head 311 to move away from the receiving cavity, thereby avoiding the first latch head 2211. After the second latch head 311 passes the first latch head 2211, the spring-loaded member 7 resets and moves the second latch head 311 closer to the receiving cavity, so that the first latch head 2211 and the second latch head 311 overlap vertically. During separation, the mounting base 3 is pulled outwards. The second latch 31 rotates and squeezes the spring-loaded member 7. After the second latch head 311 passes the first latch head 2211, the spring-loaded member 7 resets and causes the second latch 31 to rotate back to its original position. The spring-loaded component 7 provides a force for the reset of the second latch 31. It has a simple structure and facilitates the assembly and disassembly of the upper mold 1 and the lower mold 2.

[0054] In some embodiments, such as Figure 4 and Figure 5 As shown, multiple first latches 221 and multiple second latches 31 are provided. Multiple first latches 221 are distributed on opposite sides of the base 22. Multiple second latches 31 are distributed on opposite sides of the mounting base 3. The multiple first latches 221 and multiple second latches 31 are matched one-to-one to further ensure the connection stability between the mounting base 3 and the base 22, increase the constraint force of the mounting base 3 and the base 22 on the upper mold 1 and the lower mold 21, prevent the upper mold 1 and the lower mold 2 from shifting during assembly, further ensure the assembly effect of the battery cover 200 and the housing 100, and guarantee the assembly accuracy of the electronic device. It is understood that the multiple first latches 221 located on the same side of the base 22 are spaced apart along the length of the accommodating cavity, and the number of first latches 221 located on different sides of the base 22 can be the same or different, as long as the multiple first latches 221 and multiple second latches 31 are matched one-to-one.

[0055] In some embodiments, such as Figure 2As shown, the mounting base 3 and the upper mold 1 are connected by adjusting bolts 5. The mounting base 3 is movably fitted onto the adjusting bolts 5 so that after the mounting base 3 and the lower mold 2 are connected together, the mounting base 3 can move downward relative to the adjusting bolts 5 to compress the elastic element 4. Multiple adjusting bolts 5 are distributed on the mounting base 3 to ensure uniform pressure of the mounting base 3 on various areas of the upper mold 1, thereby ensuring the assembly effect of the housing 100 and the battery cover 200.

[0056] For example, multiple adjusting bolts 5 are arranged in a square array. Optional, such as... Figure 2 As shown, there are four adjusting bolts 5 arranged in a square array. Of course, multiple adjusting bolts 5 can also be arranged in a ring or a rectangular array, as long as the uniformity of the clamping force of the mounting base 3 on each area of ​​the upper mold 1 can be guaranteed.

[0057] In one specific embodiment, such as Figure 2 As shown, the elastic element 4 includes multiple elastic elements. Some elastic elements 4 are sleeved on the adjusting bolt 5, and one end of the other elastic elements 4 is connected to the mounting base 3, and the other end is connected to the upper mold 1.

[0058] The number of elastic elements 4 can be four, six, or seven, etc., and there is no specific limitation. Multiple elastic elements 4 are evenly distributed to ensure the uniformity of the pressing force of the upper mold 1 on the battery cover 200 after the mounting base 3 and the lower mold 2 are connected.

[0059] In this embodiment, one end of the elastic element 4 fitted on the adjusting bolt 5 abuts against the upper mold 1, and the other end abuts against the mounting base 3. The mounting base 3 moves closer to the upper mold 1 to press the elastic element 4, connecting the mounting base 3 and the upper mold 1. At this time, the elastic element 4 fitted on the adjusting bolt 5 can be guided by the adjusting bolt 5 to prevent the elastic element 4 from tilting. Other elastic elements 4 not fitted on the adjusting bolt 5 are fixedly connected at one end to the mounting base 3 and at the other end to the upper mold 1.

[0060] In some embodiments, one of the mounting base 3 and the lower mold 2 is provided with a positioning post 32, and the other is provided with a positioning hole 222. The positioning post 32 is pluggable and detachable in the positioning hole 222.

[0061] Specifically, the positioning post 32 protrudes from the side of the mounting base 3 facing the lower mold 2. In the case where the lower mold 2 includes a base 22 and a lower template 21, a positioning hole 222 is provided in the base 22. The positioning post 32 is inserted into the positioning hole 222 to position the connection between the mounting base 3 and the lower mold 2, ensuring a tight connection between the mounting base 3 and the base 22, thereby ensuring accurate correspondence between the upper mold 1 and the lower template 21, and guaranteeing the assembly accuracy of the battery cover 200 and the housing 100.

[0062] In some embodiments, such as Figure 2 As shown, the electronic device assembly fixture also includes a guide rod 8 and a cap 81 disposed at one end of the guide rod 8. The end of the guide rod 8 away from the cap 81 passes through the mounting base 3 and is fixedly connected to the upper mold 1.

[0063] The cap is used to prevent the mounting base 3 from detaching from the guide rod 8. Specifically, the mounting base 3 has a through hole corresponding to the guide rod 8, and the through hole of the guide rod 8 is fixedly connected to the upper mold 1 so as to provide guidance for the up and down movement of the mounting base 3 through the guide rod 8, preventing the upper mold 1 from tilting and misaligning with the battery cover 200 under the influence of the elastic element 4, and ensuring that the upper mold 1 and the battery cover 200 always remain in contact during the assembly process, thereby ensuring the assembly accuracy of the electronic device assembly fixture for the electronic device. The bottom of the guide rod 8 can be fixedly connected to the upper mold 1 by thread or by other means such as plug-in fixing.

[0064] In some embodiments, such as Figure 6 As shown, the mounting base 3 has a groove 33. The cap 81 is accommodated in the groove 33. The bottom of the groove 33 has a through hole for the guide rod 8 to pass through.

[0065] The guide rod 8 passes through the through hole and connects to the upper mold 1, while the cap body 81 is housed within the groove 33. When the upper mold 1 and the lower mold 2 are connected, the cap body 81 is housed within the groove 33; when the upper mold 1 and the lower mold 2 are separated, the cap body 81 abuts against the bottom of the groove 33. This cooperation between the cap body 81 and the groove 33 prevents the mounting base 3 from detaching from the guide rod 8 during vertical movement.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
