Description

Technical Field

[0001] This utility model relates to the field of core board technology, and in particular to an embedded CPE core board. Background Technology

[0002] In the mobile communications field, as users demand increasingly higher levels of functionality and aesthetics from 4G, 5G, and CPE products, core boards will inevitably see widespread application. A core board packages the core functions of a CPE into a single electronic board, primarily integrating a CPU, power management, storage unit, 4G / 5G modem, Wi-Fi 6, W / LAN, SIM / eSIM, and other functions. Through peripheral interfaces and customized interface boards, it can be paired with various CPE products suitable for different users, significantly shortening the overall product development cycle and enabling rapid market launch.

[0003] In existing technologies, core boards are generally installed using screws. This installation method has significant drawbacks, namely, it does not have the function of quick disassembly and assembly. When it is necessary to upgrade or maintain the core board's hardware or software, the staff has to use a screwdriver to remove multiple screws one by one to complete the disassembly process. This process is cumbersome and time-consuming, which not only increases maintenance costs, but may also cause the screws to loosen or be damaged due to frequent disassembly and assembly, thereby affecting the stability and service life of the core board.

[0004] Therefore, an embedded CPE core board needs to be designed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an embedded CPE core board.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An embedded CPE core board includes:

[0008] Core board body;

[0009] Four mounting ports are respectively located at the four corners of the core board body;

[0010] Four fixing blocks are respectively placed in the four mounting ports;

[0011] Four top slots are respectively formed on the top surface of the four fixed blocks;

[0012] Four threaded openings are respectively opened on the bottom surface of the four fixing blocks, and the four threaded openings are respectively connected to the four top grooves;

[0013] Four fixing screws are threaded into the four threaded openings respectively;

[0014] Four limiting structures are respectively set on the four fixed blocks;

[0015] Four snap-fit ​​structures are respectively installed in the four top slots.

[0016] As a preferred embodiment of this utility model, the limiting structure includes:

[0017] The insert block is movably inserted into the top groove;

[0018] An upper limit ring is fixedly sleeved on the top of the insert block;

[0019] The lower limit ring is fixedly sleeved on the fixed block.

[0020] As a preferred embodiment of this utility model, the snap-fit ​​structure includes:

[0021] A spring, one end of which is connected to the bottom of the top groove;

[0022] A sliding ring is slidably disposed within the top groove, and the sliding ring is connected to the other end of the spring;

[0023] An annular groove is formed within the top groove;

[0024] A slot is formed on the wall of the top groove, one end of which is connected to the annular groove and the other end is connected to the opening of the top groove.

[0025] The locking block is fixed on the insert block.

[0026] As a preferred embodiment of this utility model, the outer surface of the insert block is in contact with the groove wall of the top groove.

[0027] As a preferred embodiment of this utility model, the shape of the card block is adapted to the shape of the slot.

[0028] As a preferred embodiment of this utility model, a butterfly-shaped knob is fixed to the top of the insert block.

[0029] This utility model has the following beneficial effects:

[0030] When installing the core board, simply align the four mounting ports with the fixing block and pass them through until they contact the lower limit ring. Then, install the four inserts onto the fixing block. During this process, the locking blocks on the inserts can cleverly slide into the slots and, under the action of springs, lock into the annular grooves, forming a firm locking structure. This design not only ensures the stable fixation of the core board in the vertical direction, but also provides reliable fixation in the circumferential direction through the friction between the locking blocks and the annular grooves. When the locking blocks press against the annular grooves, the upper and lower limit rings together clamp the core board, achieving a stable installation. When the core board needs to be updated for software or hardware, the staff no longer needs to use a screwdriver to remove the screws one by one. Instead, they can simply turn the four butterfly knobs to easily and quickly install and remove the core board. This innovative design greatly simplifies the operation process, saves time, reduces maintenance costs, and also avoids loosening or damage caused by frequent screw removal and installation.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0036] Reference Figure 1-3 An embedded CPE core board includes a core board body 1; four mounting ports 2, respectively located at the four corners of the core board body 1; four fixing blocks 3, respectively placed in the four mounting ports 2; four top grooves 4, respectively located on the top surface of the four fixing blocks 3; four threaded ports 5, respectively located on the bottom surface of the four fixing blocks 3, and the four threaded ports 5 are respectively connected to the four top grooves 4; and four fixing screws 6, respectively threaded into the four threaded ports 5.

[0037] The core board also includes four limiting structures, which are respectively set on four fixed blocks 3. The limiting structures include: an insert 71, which is movably inserted into the top groove 4, with the outer surface of the insert 71 and the groove wall of the top groove 4 fitting together, and a butterfly knob fixed at the top of the insert 71; an upper limiting ring 72, which is fixedly sleeved on the top of the insert 71; and a lower limiting ring 73, which is fixedly sleeved on the fixed block 3.

[0038] The core board also includes four snap-fit ​​structures, each set in one of the four top slots 4. The snap-fit ​​structures include: a spring 81, one end of which is connected to the bottom of the top slot 4; a sliding ring 82, slidably set in the top slot 4, with the other end of the sliding ring 82 connected to the spring 81; an annular groove 83, formed within the top slot 4; a slot 84, formed on the wall of the top slot 4, one end of the slot 84 communicating with the annular groove 83, and the other end communicating with the opening of the top slot 4; and a locking block 85, fixed to the insert block 71. The shape of the locking block 85 matches the shape of the slot 84. The operator aligns the locking block 85 on the insert block 71 with the slot 84, and then inserts the insert block 71 into the top slot 4, allowing the locking block 85 to slide into the slot 84. During the movement of the insert block 71 within the top slot 4, the insert block 71 compresses the sliding ring 82, causing the sliding ring 82 to compress the spring 81. Furthermore, when the locking block 85... When the 5th component moves to the position where the slot 84 and the annular groove 83 are connected, the locking block 85 cannot move further. At this time, the operator rotates the insert block 71, causing the insert block 71 to rotate. When the insert block 71 rotates, it can drive the locking block 85 to rotate, causing the locking block 85 to slide into the annular groove 83. Under the action of the spring force of the spring 81, the locking block 85 always has an upward tendency. The annular groove 83 then limits the locking block 85 in the vertical direction, causing the locking block 85 to press against the annular groove 83. When the locking block 85 presses against the annular groove 83, there is a large friction between the locking block 85 and the annular groove 83. This friction provides a fixing effect on the locking block 85 in the circumferential direction, thereby fixing the insert block 71 in the slot 84. When the operator needs to update the software and hardware of the core board body 1, they only need to rotate the four butterfly knobs to quickly install and remove the core board body 1.

[0039] The specific working principle of this utility model is as follows:

[0040] When using the embedded 4G&5G CPE core board proposed in this utility model, the operator first fixes four fixing blocks 3 to the outer casing of the device. Each of the four fixing blocks 3 is equipped with a fixing screw 6, which the operator can use to fix the fixing blocks 3 to the outer casing of the device. When installing the core board body 1, the operator first aligns the four mounting ports 2 with the four fixing blocks 3 and makes the four fixing blocks 3 pass through the four mounting ports 2 until the core board body 1 contacts the four lower limit rings 73. Then, the operator inserts the four insertion blocks 7... 1. Installed on four fixed blocks 3. Since the four limiting structures and four snap-fit ​​structures are exactly the same, only one of the limiting structures and snap-fit ​​structures will be described here. Specifically, the operator aligns the snap-fit ​​block 85 on the insert block 71 with the slot 84, and then inserts the insert block 71 into the top groove 4, so that the snap-fit ​​block 85 slides into the slot 84. During the movement of the insert block 71 in the top groove 4, the insert block 71 will squeeze the sliding ring 82, causing the sliding ring 82 to squeeze the spring 81. Furthermore, when the snap-fit ​​block 85 moves to the slot 84 and the annular groove 83... When the connection position is reached, the locking block 85 cannot move further. At this time, the operator rotates the insert block 71, causing it to rotate. The rotation of the insert block 71 drives the locking block 85 to rotate, causing it to slide into the annular groove 83. Under the elastic force of the spring 81, the locking block 85 always tends to move upwards. The annular groove 83 then acts as a limiter in the vertical direction, causing the locking block 85 to press against the annular groove 83. When the locking block 85 presses against the annular groove 83, there is significant friction between the locking block 85 and the annular groove 83. The frictional force provides a fixing effect on the locking block 85 in the circumferential direction, thereby fixing the insertion block 71 in the slot 84. When the position of the insertion block 71 is fixed, the upper limit ring 72 just contacts the core board body 1. At this time, the core board body 1 is fixed between the upper limit ring 72 and the lower limit ring 73, and the core board body 1 is immediately fixed on the four fixing blocks 3. Therefore, when the staff needs to update the software and hardware of the core board body 1, they only need to turn the four butterfly knobs to quickly disassemble and install the core board body 1, which is convenient.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
