Detailed implementation manners

[0026] To make the objectives, features, and advantages of the present disclosure more obvious and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present disclosure.

[0027] In the structure of a notebook computer, it generally includes a display end and a system end. Among them, the display end is the side with a display screen, and the system end is the side with a keyboard. Generally speaking, the display end and the system end can be rotatably opened and closed.

[0028] Among them, the system end includes an upper housing and a lower housing. The upper housing and the lower housing enclose a receiving cavity, and various electronic components are loaded in this receiving cavity. Taking the main circuit board as an example of the electronic component, during application, the main circuit board is generally electrically connected to the main board external card through a connector. Exemplarily, the main board external card includes, but is not limited to, a WWAN card (Wireless Wide Area Network card) or an SSD (Solid State Drive, all - solid - state drive). Considering the installation stability of the hardware structure, it is also necessary to limit and install the WWAN and SSD in a certain position to avoid shaking. The existing fixing device uses screws to fix to the main circuit board. In order to prevent the screws from falling off, fixing washers are used to match the holes and tighten the screws. During the installation process, it is necessary to position the fixing washers and the screws relative to the positioning holes. In this way, the material cost of the fixing washers and the labor cost of installation are increased.

[0029] To alleviate the above problems, refer to Figures 1 - 5, an embodiment of the present disclosure provides a limit locking device 001. The mounting hole 121 in the carrier 10 loaded with the main board external card 30 is sleeved on the outer periphery of the fixing member 20 from top to bottom. At this time, along the length direction of the main board external card 30, when the carrier 10 is pulled, the fixing member 20 can be detachably engaged with the edge of the mounting hole 121. In this way, it is possible to fix the main board external card 30 to one side of the main circuit board 40 without external locking members such as screws.

[0030] For the convenience of description, the length direction of the main board external card 30 is defined as the first direction X, and the thickness direction of the main board external card 30 is defined as the second direction Y.

[0031] Specifically, the limit locking device 001 of the embodiment of the present disclosure includes: a carrier 10 and a fixing member 20. Among them, the carrier 10 has a carrying portion and a positioning portion 12. The carrying portion is used to accommodate the main board external card 30. Along the first direction X, the carrying portion has a channel for inserting the main board external card 30; one end of the plug connector of the main board external card 30 is arranged away from the positioning portion 12, and the positioning portion 12 has a mounting hole 121; the fixing member 20 is positioned and installed at a preset position, the fixing member 20 is sleeved in the mounting hole 121, and along the first direction X, when the positioning portion 12 is pulled, the fixing member 20 is configured to be detachably engaged with the edge of the mounting hole 121.

[0032] In actual assembly, the fixing member 20 is pre-installed at a preset position on the main circuit board 40. Along the first direction X, the main board external card 30 is inserted into the channel of the carrying portion in the carrier 10. Then, one end of the main board external card 30 is inserted into the connector port on the main circuit board 40, and the other end of the main board external card 30 is on the side close to the positioning portion 12 in the carrier 10. The carrier 10 with the main board external card 30 is directly sleeved on the outer periphery of the positioning portion 12 through the mounting hole 121 of the positioning portion 12. This process is simple and easy to operate and can be completed without precise alignment. Then, along the direction from the carrying portion to the positioning portion 12, that is, the first direction X, the positioning portion 12 is pulled. In this way, the fixing member 20 can be detachably engaged with the edge of the mounting hole 121. In this solution, without using screw-type locking members for fixing and assembling, by applying the carrier 10 and the fixing member 20 of this solution, limit installation can be directly carried out without the need to rely on fixing washers, which can save materials and installation costs, improve the assembly efficiency of the limit installation of the main board external card 30 relative to the main circuit board 40, and also improve the disassembly and assembly convenience of the main board external card 30.

[0033] Exemplarily, the carrying portion and the positioning portion 12 are an integrally formed structure, and the whole forms an integrally formed sheet metal structure. The carrier 10 of the embodiment of the present disclosure is made of a metal material, including but not limited to any one of iron, stainless steel or copper. The carrier 10 needs to have high structural strength to have a stable bearing capacity for loading the main board external card 30.

[0034] Considering that the bearing part can ensure that the main board external card 30 can be stably inserted and can be stably supported, in the limit locking device 001 of the present disclosure embodiment, the bearing part wraps around the outer periphery of the main board external card 30, and at least part of the structure of the bearing part is used to support the bottom surface of the main board external card 30. Exemplarily, the bearing part includes a first plane 111, a first support sub-part 112 and a second support sub-part 113. The first support sub-part 112 and the second support sub-part 113 are respectively connected to both ends of the first plane 111. The first plane 111, the first support sub-part 112 and the second support sub-part 113 together wrap the main board external card 30 inside. The first support sub-part 112 includes a first support plane 1121 for supporting the main board external card 30, and the second support sub-part 113 includes a second support plane 1131 for supporting the main board external card 30. The first support plane 1121 and the second support plane 1131 are spaced apart. The first support sub-part 112 further includes a first vertical surface 1122, and the first vertical surface 1122 is connected between the first plane 111 and the first support plane 1121. The second support sub-part 113 further includes a second vertical surface 1132, and the second vertical surface 1132 is connected between the first plane 111 and the second support plane 1131. In this way, the first support plane 1121, the first vertical surface 1122, the first plane 111, the second vertical surface 1132 and the second support plane 1131 together enclose the aforementioned channel for the insertion of the main board external card 30.

[0035] Considering that the bearing member 10 needs to be simultaneously acted on by the fixing member 20 and the main circuit board 40 to be stably placed between the fixing member 20 and the main circuit board 40, in the limit locking device 001 of the present disclosure embodiment, at least one side of the bearing part has a positioning protrusion 114, and the positioning protrusion 114 protrudes from the bottom surface of the main board external card 30. The positioning protrusion 114 is configured as a planar structure extending along the second direction Y. Exemplarily, the positioning protrusion 114 is formed on the second vertical surface 1132 in the third support sub-part of the bearing part. Correspondingly, the main circuit board 40 has a card hole engaged with the positioning protrusion 114.

[0036] Considering the structure of the main board external card 30 and the stable state of the main board external card 30 inserted into the bearing member 10, in the limit locking device 001 of the present disclosure embodiment, the positioning part 12 includes a blocking part 122, and the blocking part 122 is used to block the continuous insertion of the main board external card 30 along the first direction X. Exemplarily, the blocking part 122 is configured as an edge structure formed by bending the first plane 111 downward. The blocking part 122 is integrally connected with the positioning part 12.

[0037] Considering the action that the carrier 10 can be slidably engaged with the fixing member 20 through the mounting hole 121 of the positioning portion 12, in the limit locking device 001 of the embodiment of the present disclosure, the mounting hole 121 of the positioning portion 12 includes a first hole 1211 and a second hole 1212. The first hole 1211 and the second hole 1212 are communicated along their own radial directions. The aperture of the first hole 1211 is smaller than the aperture of the second hole 1212, and the first aperture is located between the blocking portion 122 and the second hole 1212. In this way, the fixing member 20 is preferentially sleeved in the second hole 1212 with a large aperture, and then the carrier 10 is pulled. The carrier 10 moves relative to the fixing member 20. In this way, the fixing member 20 can be engaged with the edge of the first hole 1211 with a small aperture.

[0038] In order to achieve the movable engagement between the fixing member 20 and the first hole 1211, in the limit locking device 001 of the embodiment of the present disclosure, the fixing member 20 is configured as a cylindrical structure. The fixing member 20 includes an upper fixing portion 21 and a lower fixing portion 22 located below the upper fixing portion 21. There is an annular groove 23 between the upper fixing portion 21 and the lower fixing portion 22. The radial dimensions of the upper fixing portion 21 and the lower fixing portion 22 are smaller than the aperture of the second hole 1212, and the radial dimensions of the upper fixing portion 21 and the lower fixing portion 22 are larger than the aperture of the first hole 1211; along the first direction X, the annular groove 23 and the edge of the first hole 1211 are configured to be detachably engaged. With the above structure of the fixing member 20, the overall structure is a rotating body structure, which is convenient for processing and forming, has a low production cost, and is matched with the mounting hole 121 communicated with the large and small apertures, and can quickly fix the main board external card 30 on one side of the main circuit board 40.

[0039] Considering that the carrier 10 can be suitable for the insertion and loading of a wireless wide area network card, in the limit locking device 001 of the embodiment of the present disclosure, a stepped surface is formed on the top surface of the bearing portion by connecting with the positioning portion 12 through the blocking portion 122; an annular boss 24 protrudes from the lower fixing portion 22 along its own radial direction, and the annular boss 24 is engaged with the positioning groove 31 of the main board external card 30. At the same time, combined with the carrier 10 being engaged with another preset position on the main circuit board 40 through the positioning protrusion portion 114, it can ensure that the carrier 10 loaded with the wireless wide area network card will not rotate relative to the main circuit board 40.

[0040] Further, considering the convenience of pulling the positioning portion 12, in the limit locking device 001 of the embodiment of the present disclosure, the positioning portion 12 further includes a pushing and pulling portion 123. The pushing and pulling portion 123 is formed on the side of the positioning portion 12, and the pushing and pulling portion 123 is disposed opposite to the blocking portion 122. Exemplarily, the pushing and pulling portion 123 is configured as a vertical surface structure extending upward from the side of the positioning portion 12. When encountering a narrow space or other difficult-to-assemble environments, a labor-saving pulling belt can be installed on the pushing and pulling portion 123 to facilitate pushing or pulling the carrier 10.

[0041] An embodiment of the present disclosure further provides an electronic device, which includes the above-mentioned limiting and locking device 001, and also includes a main board external card 30 and a main circuit board 40. The main board external card 30 has a positioning groove 31. The main board external card 30 is inserted into the bearing part along the first direction X. The fixing part 20 is positioned and installed at a preset position of the main circuit board 40. At least part of the structure of the fixing part 20 is engaged with the positioning groove 31. By pulling the positioning part 12, at least part of the structure of the fixing part 20 is detachably engaged with the edge of the mounting hole 121. In this way, all the effects of the above-mentioned limiting and locking device 001 can be achieved, which will not be elaborated here.
