Description

Technical Field

[0001] This utility model relates to the field of network set-top box motherboard technology, specifically a network set-top box motherboard assembly that is easy to disassemble. Background Technology

[0002] Network set-top boxes are crucial technological devices in information appliances. Their function has evolved from a multi-frequency tuner and decoder to a control terminal for a vast online database of movies, multimedia events, news, and more. The internal motherboard is the heart of the set-top box, responsible for the operation of all its functions.

[0003] In existing technologies, when it is necessary to repair the set-top box motherboard, the staff must first completely disassemble the set-top box casing. After the casing is removed, since the motherboard is usually fixed inside the set-top box with multiple bolts, the staff needs to unscrew them one by one using matching tools. During this process, care must be taken not only to avoid losing bolts, but also to prevent the motherboard from deforming or the solder joints from falling off due to uneven force. This undoubtedly prolongs the preparation time for repair and significantly reduces work efficiency. Therefore, we propose a network set-top box motherboard assembly that is easy to disassemble. Summary of the Invention

[0004] The purpose of this invention is to provide a network set-top box motherboard assembly that is easy to disassemble, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a network set-top box motherboard assembly that is easy to disassemble, comprising a first outer shell, a second outer shell, and a motherboard body. The first outer shell has a circular connection port on its rear right side, and a heat dissipation groove on its exterior. It also includes:

[0006] A limiting component is located inside the second outer casing, and the motherboard body is installed and fixed by the limiting component.

[0007] The positioning component is located on the inner wall of the outer casing and is used to position the motherboard body during installation.

[0008] The limiting component includes a mounting groove, a telescopic rod is fixedly connected inside the outer shell, a spring is sleeved on the outside of the telescopic rod, a limiting sleeve is fixedly connected to the bottom of the telescopic rod, and a limiting groove is opened inside the limiting sleeve.

[0009] The positioning component includes a support plate, and a magnetic plate 1 is set inside the positioning component. Two mounting plates are fixedly connected to the bottom of the motherboard body, and a magnetic plate 2 is set inside the mounting plate.

[0010] The bottom of the outer casing is provided with a fixing component, the fixing component is internally threaded with a fixing bolt, the inner part of the outer casing is fixedly connected with a fixing block, and the fixing bolt is externally threaded to the inside of the fixing block.

[0011] Among them, the bottom four corners of the outer shell are all fixedly connected with support pads.

[0012] The outer shell has an interface 1 on its exterior and an interface 2 on its rear left side.

[0013] The inside of the limiting groove is in contact with the outside of the limiting component, one side of the spring is fixedly connected to the outside of the limiting sleeve, and the other side of the spring is fixedly connected to the inside of the outer shell.

[0014] This utility model has at least the following beneficial effects:

[0015] When in use, the magnetic sheet one and magnetic sheet two of the positioning component attract each other, allowing the motherboard body to be quickly adsorbed into the correct position without the need to repeatedly align the bolt holes, facilitating quick installation. During disassembly, the magnetic force of the magnetic sheets can be easily overcome, allowing the motherboard to be removed directly, avoiding the tedious process of unscrewing each bolt one by one, and reducing maintenance preparation time.

[0016] The spring of the limiting component works with the telescopic rod to automatically limit the edge of the motherboard through the limiting sleeve when the outer shell is closed. During disassembly, after unscrewing the fixing bolt, the spring drives the limiting sleeve to reset, releasing the constraint on the motherboard. The whole process does not require special tools, and a single person can complete the disassembly and installation of the motherboard. At the same time, the fixing bolt of the fixing component passes through the second outer shell and is screwed into the fixing block to firmly connect the first outer shell and the second outer shell. Together with the limiting sleeve, it limits the pushing movement of the motherboard from all sides. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1 to 6 This utility model provides a technical solution: a network set-top box motherboard assembly that is easy to disassemble, including a first outer shell 1, a second outer shell 101, and a motherboard body 102. A circular connection port 702 is provided on the right rear side of the first outer shell 1, and a heat dissipation groove 5 is provided on the outside of the first outer shell 1. It also includes:

[0027] Limiting component 2 is disposed inside the outer casing 101 and is used to install and fix the motherboard body 102.

[0028] Positioning component 3 is set on the inner wall of outer shell 2 101. Positioning component 3 is used to position the motherboard body 102 during installation. Outer shell 1 and outer shell 2 101 constitute the outer shell. Heat dissipation groove 5 dissipates heat. Support pad 6 is placed stably. Interface 1 7, interface 2 701 and circular connection port 702 are connected to external devices.

[0029] The limiting component 2 includes a mounting groove 201. A telescopic rod 202 is fixedly connected inside the outer shell 1. A spring 203 is sleeved on the outside of the telescopic rod 202. A limiting sleeve 204 is fixedly connected to the bottom of the telescopic rod 202. A limiting groove 205 is opened inside the limiting sleeve 204. The inside of the limiting groove 205 contacts the outside of the limiting component 2. One side of the spring 203 is fixedly connected to the outside of the limiting sleeve 204, and the other side of the spring 203 is fixedly connected to the inside of the outer shell 1. After positioning, the main board slides along the mounting groove 201 to the outside of the limiting component 2, closing the outer shell 1 and the outer shell 2 101. The spring 203 outside the telescopic rod 202 pushes the limiting sleeve 204 down. The limiting groove 205 slides outside the limiting component 2, pushing against the edge of the main board, thus limiting the main board from all sides.

[0030] The positioning component 3 includes a support plate 301 and a magnetic plate 302 inside the positioning component 3. Two mounting plates 303 are fixedly connected to the bottom of the motherboard body 102, and a magnetic plate 304 is inside the mounting plate 303. When installing the motherboard body 102, the magnetic plate 302 of the positioning component 3 and the magnetic plate 304 of the mounting plate 303 attract each other, so that the motherboard is quickly attached to the correct position to complete the initial positioning.

[0031] The bottom of the outer casing 1 is provided with a fixing component 4, and a fixing bolt 401 is threadedly connected inside the fixing component 4. A fixing block 402 is fixedly connected inside the outer casing 1, and the fixing bolt 401 is threadedly connected to the inside of the fixing block 402. The fixing bolt 401 of the fixing component 4 passes through the outer casing 2 101 and is screwed into the fixing block 402, so as to firmly connect the outer casing 1 and the outer casing 2 101 and further fix the motherboard.

[0032] Support pads 6 are fixedly connected to the four corners of the bottom of the outer casing 101. Interface 7 is opened on the outside of the outer casing 1, and interface 701 is opened on the left side of the rear end of the outer casing 1. Interface 7 is opened on the outside of the outer casing 1 and is used to connect external devices.

[0033] The working principle of this utility model is as follows: the outer shell 1 and the outer shell 2 101 together constitute the outer shell of the network set-top box, providing installation space and protection for the motherboard body 102. The heat dissipation groove 5 on the outside of the outer shell 1 is used to dissipate the heat generated by the motherboard during operation and avoid overheating affecting performance. The support pads 6 at the four corners of the bottom of the outer shell 2 101 make the set-top box more stable. The interface 1 7, interface 2 701 and the circular connection port 702 on the outer shell are used to connect external devices.

[0034] When installing the motherboard body 102, the positioning component 3 plays a role in rapid positioning. The positioning component 3 is equipped with a magnetic sheet 302, and the mounting plate 303 at the bottom of the motherboard body 102 is equipped with a magnetic sheet 304. When the motherboard body 102 is placed inside the outer casing 101, the magnetic sheet 302 and the magnetic sheet 304 attract each other, so that the motherboard body 102 is quickly attracted to the correct position, achieving preliminary positioning and avoiding positional deviation during installation.

[0035] After positioning, the motherboard body 102 will slide outside the limiting component 2 in conjunction with the internal mounting slot 201. At the same time, the telescopic rod 202 inside the outer shell 1 is fitted with a spring 203. When the outer shell 1 and the outer shell 2 101 are closed, the limiting sleeve 204 moves downward under the elastic force of the spring 203, and the limiting groove 205 inside slides outside the limiting component 2. At the same time, it pushes against the edge of the motherboard body 102, limiting the motherboard body 102 from all sides.

[0036] When it is necessary to disassemble the motherboard body 102, first unscrew the fixing bolt 401 of the fixing component 4 to separate the outer shell 1 from the outer shell 2 101. At this time, the spring 203 of the limiting component 2 returns to its original state, driving the telescopic rod 202 and the limiting sleeve 204 to reset. The limiting sleeve 204 no longer limits the motherboard body 102. Since the magnetic adsorption force of the positioning component 3 can be easily overcome, the motherboard body 102 can be directly removed to complete the disassembly. The whole process does not require complicated operations and achieves the effect of quick disassembly.

[0037] Example 2

[0038] Please see Figure 3 and Figure 6 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the fixing bolt 401 of the fixing component 4 passes through the outer shell 2 101 and is screwed into the fixing block 402, which firmly connects the outer shell 1 and the outer shell 2 101, further fixing the main board body 102 and ensuring that it will not shake during use.
