[0046] The following describes a laptop computer 100 according to the present invention with reference to the accompanying drawings.

[0047] It should be noted that Figure 1 For the convenience of expression, the lower shell 190 is exploded into the first shell 170 and the second shell 180 for display. When the computer motherboard 110 is actually installed in the lower shell 190, the first shell 170 and the second shell 180 are connected together. Figure 9 and Figure 11 In order to clearly express the internal structure of the lower housing 190, the second housing 180 is hidden and only the first housing 170 is shown. Figure 1 The length direction of the lower shell 190 is the x-axis direction, the width direction of the lower shell 190 is the y-axis direction, and the height direction of the lower shell 190 is the z-axis direction.

[0048] Reference Figure 1 、 Figure 3 、 Figure 8 and Figure 12 According to an embodiment of the present invention, a laptop computer 100 includes a lower housing 190, a plug-in module 160, and a computer motherboard 110. The lower housing 190 is provided with a receiving cavity 140 and a first connecting portion 270. The lower housing 190 has a predetermined length and is further provided with two opposing side portions along its length. One of the side portions is provided with a first hole 130, which communicates with the receiving cavity 140. The plug-in module 160 is disposed within the receiving cavity 140 and is provided with a first plug-in portion 150. The computer motherboard 110 is provided with a second plug-in portion 360 and a second connecting portion 260. The first connecting portion 270 is fixedly connected to the second connecting portion 260. The second plug-in portion 360 is disposed opposite the first plug-in portion 150 along the length of the lower housing 190. The computer motherboard 110 can slide into the receiving cavity 140 along the first hole 130, so that the second plug-in portion 360 is pluggably connected to the first plug-in portion 150. The notebook computer 100 of this embodiment can be assembled with the computer motherboard 110 from the side, thereby reducing the assembly steps of the computer motherboard 110 and lowering the assembly difficulty.

[0049] Specifically, the first connection portion 270 can be a first through-hole provided on the first housing 170 and a threaded hole provided on the second housing 180, with the threaded hole corresponding to the position of the first through-hole. The second connection portion 260 can be a second through-hole provided on the computer motherboard 110, with the position of the second through-hole corresponding to the first through-hole. By fastening the first and second connection portions 270, 260 with bolts, a fixed connection between the first and second connection portions 270, 260 can be achieved. The first plug portion 150 and the second plug portion 360 are electrically connected through a pin-and-socket arrangement to electrically connect other components of the laptop computer 100, such as the screen, power supply, and touchpad, to the computer motherboard 110.

[0050] When the computer motherboard 110 needs to be assembled, the computer motherboard 110 is inserted into the accommodating cavity 140 along the first hole 130, and the first plug-in portion 150 and the second plug-in portion 360 are aligned and plugged in. Then, the first connecting portion 270 and the second connecting portion 260 can be locked and pre-tightened by bolts to achieve relative fixation of the computer motherboard 110 and the lower shell 190, thereby completing the assembly of the computer motherboard 110 and the lower shell 190.

[0051] Furthermore, the computer motherboard 110 is provided with multiple identical or different peripheral interfaces 610, such as a USB interface, a Type-C interface or an HDMI interface, etc. The type of the peripheral interface 610 can be freely selected according to different needs. During production, only different types of computer motherboards 110 need to be replaced, which is conducive to the modularization of the laptop computer 100.

[0052] Reference Figure 2 According to some embodiments of the present invention, the laptop computer 100 further includes a clamping member 120, which is disposed on the first connecting portion 270. The second connecting portion 260 is provided with a limiting portion 340. The clamping member 120 is disposed opposite the limiting portion 340. The clamping member 120 is configured to abut against the limiting portion 340 to securely engage the first connecting portion 270 with the second connecting portion 260. This clamping fixation method can eliminate the need for bolting, further improving assembly efficiency.

[0053] Specifically, the limiting portion 340 can be configured as a limiting groove 290. The lower housing 190 is provided with a sliding groove 280 and a sliding hole 210. The sliding hole 210 is connected to the sliding groove 280. The clamping member 120 can be configured as a limiting member 250. The limiting member 250 is provided with a pull rod 220 and a first abutting portion 230. The pull rod 220 is disposed in the sliding hole 210 and can move along the axial direction of the sliding hole 210. The sliding hole 210 is provided with a second elastic member 205. The second elastic member 205 can be configured as an elastic element such as a spring or a bellows. The second elastic member 205 drives the first abutting portion 230 toward the computer motherboard 110. When the limiting groove 290 is aligned with the first limiting portion 330, the first limiting portion 330 can enter the limiting groove 290, thereby limiting the movement of the computer motherboard 110 out of the accommodating cavity 140. When the computer motherboard 110 needs to be unlocked, the pull rod 220 is pulled down in a direction away from the computer motherboard 110 to unlock the computer motherboard 110 and release the restriction on the displacement of the computer motherboard 110 .

[0054] Furthermore, the limiting member 250 is also provided with a second supporting portion 240, which is arranged between the first supporting portion 230 and the pull rod 220. The second supporting portion 240 can slide along the sliding hole 210. The inner surface of the upper shell is also fixed with a limiting block 200. The limiting block 200 is used to abut against the second supporting portion 240, thereby limiting the movement of the second supporting portion 240 out of the sliding hole 210, so as to reduce the probability of the limiting member 250 directly bouncing into the accommodating cavity 140 due to the elastic force of the second elastic member 205.

[0055] Reference Figures 3 to 7 、 Figure 11 and Figure 12 According to some embodiments of the present invention, the lower housing 190 has a predetermined width. The first connecting portion 270 is located on the bottom surface of the lower housing 190 near the first hole 130. The first connecting portion 270 is provided with a second hole 810 that communicates with the accommodating cavity 140. The limiting portion 340 includes a first boss 320. The clamping member 120 includes a second boss 410 and a dial button 500. The clamping member 120 has opposing first and second side portions 460 and 450. The dial button 500 is disposed on the first side portion 460 and the second boss 410 is disposed on the second side portion 450. The dial button 500 is inserted into the second hole 810 and can slide along the width direction of the lower housing 190 so that the second boss 410 at least partially overlaps with the first boss 320 along the length direction of the lower housing 190. In this embodiment, the laptop computer 100 can achieve a clamping and fixing of the lower housing 190 to the computer motherboard 110 via the clamping member 120.

[0056] Specifically, along the length direction of the lower shell 190, the size of the second hole 810 and the size of the dial button 500 can be set to be adaptive, so that the hole wall of the second hole 810 can be abutted against the side wall of the dial button 500, thereby limiting the movement of the dial button 500 along the length direction of the lower shell 190, and then maintaining the movement of the clamping part 120 along the width direction of the lower shell 190.

[0057] When assembling the computer motherboard 110 with the lower housing 190, the toggle button 500 is first toggled to move the clamping member 120 so that the second boss 410 and the first boss 320 do not interfere with each other in the longitudinal direction of the lower housing 190, thereby smoothly pushing the computer motherboard 110 into the accommodating cavity 140 along the first hole 130. When the computer motherboard 110 moves to the point where the distance between the first boss 320 and the opening of the first hole 130 is greater than the distance between the second boss 410 and the opening of the first hole 130, and there is no interference between the first boss 320 and the second boss 410 in the width direction of the lower housing 190, the toggle button 500 is then toggled to move the clamping member 120 so that the second boss 410 at least partially overlaps with the first boss 320 in the longitudinal direction of the lower housing 190. The second boss 410 restricts the movement of the first boss 320 out of the accommodating cavity 140, thereby achieving the clamping and fixing of the computer motherboard 110 to the lower housing 190.

[0058] Furthermore, by controlling the extension length of the second hole 810 along the width direction of the lower shell 190, the movement distance of the button 500 along the width direction of the lower shell 190 can be limited, thereby limiting the movement position of the second boss 410 to accurately control the relative position relationship between the second boss 410 and the first boss 320.

[0059] Reference Figure 3 、 Figure 6 and Figure 7 According to some embodiments of the present invention, the limiting portion 340 further includes a first limiting portion 330. The first limiting portion 330 extends along the length of the lower housing 190. The first limiting portion 330 is configured to abut against the second boss 410 in the width direction of the lower housing 190 to limit movement of the clamping member 120 along the width direction of the lower housing 190. The provision of the first limiting portion 330 ensures that the second boss 410 is positioned correctly to limit the first boss 320.

[0060] Specifically, after the computer motherboard 110 is pushed into the accommodating cavity 140 and inserted, the toggle button 500 is driven to move the second boss 410. The second boss 410 overlaps with the first boss 320 in the longitudinal direction of the lower housing 190, thereby limiting the movement of the computer motherboard 110 out of the accommodating cavity 140. When the second boss 410 moves to abut against the first limiting portion 330, the first limiting portion 330 limits the second boss 410 from further movement along the width direction of the lower housing 190. This ensures that when the computer motherboard 110 needs to be locked, the second boss 410 and the first boss 320 have sufficient overlapping area in the longitudinal direction of the lower housing 190 to ensure locking stability and reduce the possibility of the second boss 410 being dislocated from the set position due to excessive movement of the toggle button 500.

[0061] Reference Figure 6 and Figure 7 According to some embodiments of the present invention, the limiting portion 340 further includes a first guide portion 300. A first boss 320 and the first guide portion 300 are sequentially arranged along the width direction of the lower housing 190. A slope 310 is provided on the side of the first guide portion 300 facing the first boss 320. The angle between the slope 310 and the length direction of the lower housing 190 is greater than zero. The clamping member 120 further includes a second guide portion 400. One end of the second guide portion 400 is connected to one end of the second boss 410. The other end of the second guide portion 400 extends along the inclination direction of the slope 310. The slope 310 can abut against the second guide portion 400. The provision of the first guide portion 300 and the second guide portion 400 can reduce the probability of the computer motherboard 110 becoming stuck when sliding into the accommodating cavity 140. Furthermore, the toggle button 500 can be used to push a portion of the computer motherboard 110 out of the accommodating cavity 140.

[0062] Specifically, a certain gap is provided between the first boss 320 and the first guide portion 300 to allow the second boss 410 to pass through. When the computer motherboard 110 slides into the accommodating cavity 140 and moves to a certain position, the second guide portion 400 abuts against the inclined surface 310 of the first guide portion 300. The second boss 410 moves along the inclined surface 310 and slides into the gap between the first boss 320 and the first guide portion 300. This allows the second boss 410 and the first boss 320 to be aligned in the direction in which the computer motherboard 110 slides into the accommodating cavity. The toggle button 500 is then toggled to move the second boss 410 along the width of the lower housing 190, causing the second boss 410 to overlap with the first boss 320 along the length of the lower housing 190, thereby achieving a snap-fit fixation of the computer motherboard 110.

[0063] When the computer motherboard 110 needs to be removed, the dial button 500 is toggled, forcing the second boss 410 to move toward the first guide portion 300. When the second guide portion 400 contacts the inclined surface 310, the force applied by the second guide portion 400 on the first guide portion 300 along the width direction of the lower housing 190 is converted by the inclined surface 310 into a component force along the length direction of the lower housing 190. Under the action of this component force, the computer motherboard 110 moves out of the accommodating cavity 140, and the first plugging portion 150 and the second plugging portion 360 are also disconnected. A portion of the computer motherboard 110 pops out of the accommodating cavity 140, and the operator can then remove the computer motherboard 110 from the lower housing 190. Compared with the embodiment in which the first guide portion 300 and the second guide portion 400 are not provided, the laptop computer 100 of this embodiment does not need to be provided with a disassembly groove at the position of the lower shell 190 corresponding to the first hole 130 to disassemble the computer motherboard 110, nor does it need to use tools such as a suction cup to suck out the computer motherboard 110, thereby facilitating the disassembly of the computer motherboard 110.

[0064] Reference Figure 1 、 Figure 4 、 Figure 5 、 Figures 9 to 12 According to some embodiments of the present invention, the clamping member 120 is further provided with a third hole 430, which extends along the width direction of the lower shell 190, and the first connecting portion 270 is further provided with a third boss 700, which passes through the third hole 430. The third hole 430 is used to limit the movement of the third boss 700 along the length direction of the lower shell 190, and the third boss 700 can slide along the extension direction of the third hole 430.

[0065] Specifically, along the length of the lower housing 190, the size of the third hole 430 matches the size of the third boss 700. When the clip 120 tends to move along the length of the lower housing 190, the wall of the third hole 430 abuts against the outer surface of the third boss 700, thereby limiting the movement of the clip 120 along the length of the lower housing 190. The third hole 430 and the second hole 810 together limit the movement of the clip 120, maintaining the clip 120's movement along the width of the lower housing 190 and improving the stability of the clip connection.

[0066] Furthermore, by adjusting the extension length of the third hole 430 along the width direction of the lower shell 190 , the movement distance of the clamping member 120 along the width direction of the lower shell 190 can be limited, thereby accurately controlling the relative position relationship between the second boss 410 and the first boss 320 .

[0067] Reference Figures 9 to 12 According to some embodiments of the present invention, the lower shell 190 has a set height, the clamping member 120 is further provided with a fourth hole 420, the fourth hole 420 is connected to the third hole 430, and the fourth hole 420 extends along the length direction of the lower shell 190, and the first connecting portion 270 is further provided with a fourth boss 710, one end of the fourth boss 710 is connected to one end of the third boss 700, and the other end of the fourth boss 710 extends along the length direction of the lower shell 190, and the fourth boss 710 can pass through the fourth hole 420 along the height direction of the lower shell 190, and the dimension of the fourth boss 710 along the length direction of the lower shell 190 is greater than the dimension of the third hole 430 along the length direction of the lower shell 190.

[0068] Specifically, the fourth hole 420 is used to provide a mounting channel for the fourth boss 710, so that the fourth boss 710 can pass through the fourth hole 420 and be located on the side of the clip 120 away from the second hole 810. Because the dimension of the fourth boss 710 along the length of the lower shell 190 is greater than the dimension of the third hole 430 along the length of the lower shell 190, the fourth boss 710 will abut against the upper surface of the clip 120, thereby limiting the movement of the clip 120 along the height direction of the lower shell 190 and reducing the probability of the clip 120 being displaced from the set position.

[0069] According to some embodiments of the present invention, the laptop computer 100 also includes an elastic member 720, and the lower shell 190 is further provided with a mounting portion 730. The clip 120 and the mounting portion 730 are arranged in sequence along the width direction of the lower shell 190. One end of the elastic member 720 is connected to the mounting portion 730, and the other end of the elastic member 720 is connected to the clip 120.

[0070] Specifically, the elastic member 720 can be a spring. The clip 120 is provided with a mounting hole 440. One end of the elastic member 720 is mounted in the mounting hole 440, and the other end of the elastic member 720 is mounted on the mounting portion 730. Under the pull of the elastic member 720, the clip 120 always has a tendency to move toward the mounting portion 730. When the first boss 320 and the second boss 410 are in an overlapping limited state, the elastic member 720 acts to keep the clip 120 in the set position of the limited state, reducing the possibility of the clip 120 being displaced due to shaking or friction of the dial button 500, and preventing the computer motherboard 110 from being accidentally unlocked, causing the computer motherboard 110 to slide out of the accommodating cavity 140 and be damaged.

[0071] Reference Figure 8 According to some embodiments of the present invention, the lower shell 190 is further provided with a second limiting portion 620, and the second limiting portion 620 is arranged at a position corresponding to the first hole 130. The computer motherboard 110 is further provided with a third limiting portion 630. The third limiting portion 630 is located at an end of the computer motherboard 110 away from the first plug-in portion 150. Along the direction in which the computer motherboard 110 slides into the accommodating cavity 140, the second limiting portion 620 and the third limiting portion 630 are arranged in sequence, and the second limiting portion 620 is used to abut against the third limiting portion 630 in the length direction of the lower shell 190.

[0072] Specifically, the second limiting portion 620 can be arranged on the inner surface of the accommodating cavity 140 at a position corresponding to the opening of the first hole 130, and a portion of the third limiting portion 630 blocks a portion of the first hole 130, or, when the lower shell 190 has sufficient thickness, the second limiting portion 620 can also be arranged on the inner surface of the third hole 430.

[0073] The second limiting portion 620 can abut against the third limiting portion 630, thereby limiting the movement of the computer motherboard 110 into the accommodating cavity 140 and preventing the computer motherboard 110 from continuing to slide into the accommodating cavity 140 when the first plug portion 150 and the second plug portion 360 are misaligned. Furthermore, when the first plug portion 150 and the second plug portion 360 are plugged in, the abutment of the second limiting portion 620 against the third limiting portion 630 can provide structural support and cushioning for the laptop computer 100 when subjected to external impact, preventing the impact force from being directly transmitted to the first plug portion 150 and the second plug portion 360, which could damage fragile components such as the pins of the first plug portion 150 and the second plug portion 360. In addition, the second limit portion 620 can also have a certain anti-mistake function. By identifying the positions of the second limit portion 620 and the third limit portion 630, it can be determined that the posture of the computer motherboard 110 when inserted is correct, reducing the chance of damage to the first plug-in portion 150 and the second plug-in portion 360 caused by repeated plugging and unplugging or incorrect plugging of the computer motherboard 110.

[0074] Reference Figure 8 According to some embodiments of the present invention, the computer motherboard 110 includes a circuit board and a housing 600. The second plug-in portion 360 is provided on the circuit board, and the circuit board is connected to the housing 600. The housing 600 is provided with a plug-in hole, and the second plug-in portion 360 is inserted into the plug-in hole. The second connecting portion 260 is provided on the housing 600. The provision of the housing 600 can protect the circuit board and its components.

[0075] It should be noted that the plug hole is not shown in the figure.

[0076] Specifically, the housing 600 can be configured as a fully enclosed structure, with the circuit board encapsulated within the housing 600, or the housing 600 can be configured as a semi-enclosed structure, with the circuit board fixed to the housing 600. The housing is also provided with corresponding other holes to expose the interfaces of the peripheral connectors. By providing the housing 600, the components on the circuit board can be protected, reducing the chance of direct contact and friction between the components and the lower housing 190, thereby reducing the possibility of component damage and extending the service life of the computer motherboard 110. Furthermore, by providing the second connecting portion 260 on the housing 600, structural changes to the circuit board can be reduced, thereby reducing the probability of defects caused by structural processing of the circuit board.

Various modifications may be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof may be combined with one another unless there is a conflict.
