AI Technical Summary
In electronic devices, the motherboard is closely fitted with the side wall of the chassis, which leads to the collision between the bracket and the side wall of the chassis or the edge of the motherboard when assembling the expansion card, which increases the difficulty of assembly.
A motherboard is designed to include a avoiding groove provided at the edge, maintaining a gap of 2 to 3 mm between the avoiding groove and the side wall to ensure that the bracket of the expansion card does not bump into the motherboard or the side wall of the chassis when inserted.
Through the design of avoiding grooves, assemblers can insert expansion cards within a larger angle range, significantly reducing the risk of bracket collision and improving assembly convenience and efficiency.

[0002] In current electronic devices, the motherboard is assembled in the chassis, and in order to save space in the chassis and effectively reduce the overall size of the electronic device, the motherboard is placed close to the side wall of the chassis. In other words, there is almost no gap between the motherboard and the side wall of the chassis. This makes it easy for the bracket of the expansion card to collide with the side wall of the chassis or the edge of the motherboard when assembling the expansion card to the motherboard if the expansion card is misaligned with the slot and the insertion angle is too large. The assembler needs to be very careful to avoid the collision. Utility Model Content

[0035] Figure 1 is a schematic diagram of an expansion card of an electronic device of the present invention being inserted into a slot, and Figure 2 for Figure 1 Please also refer to the assembly diagram from different angles. Figure 1 and Figure 2 The electronic device 100 of this embodiment includes a chassis 110 , a mainboard 120 and an expansion card 130 .
[0036] The case 110 has a side wall 112, and the motherboard 120 is suitable for being fixed in the case 110, wherein the motherboard 120 includes a motherboard body 121, at least one slot 122, and an escape groove 124. The motherboard body 121 has an installation area 121a and an edge 121b. The slot 122 is arranged in the installation area 121a along the extension direction D1, wherein the slot 122 is used for various expansion cards 130 to be inserted therein for function expansion. The escape groove 124 is located at the edge 121b and corresponds to the position of the slot 122, and the escape groove 124 is formed concave toward the installation area 121a along the extension direction D1.
[0037] In this embodiment, the expansion card 130 may be a PCIE card or a PCI card, such as a graphics card, a network card, a USB card or a capture card, which may be selected according to the requirements.
[0038] The expansion card 130 includes a card body 132 and a bracket 134, wherein the bracket 134 is assembled with the card body 132. Specifically, the bracket 134 has a horizontal portion 134a and a vertical portion 134b, wherein the horizontal portion 134a is locked to the card body 132, and the vertical portion 134b is located at the side of the card body 132 and has a folded edge 134c. In this embodiment, the normal directions N1, N2, and N3 of the horizontal portion 134a, the vertical portion 134b, and the folded edge 134c are perpendicular to each other, wherein the normal direction N1 of the horizontal portion 134a is parallel to the normal direction N4 of the card body 132. However, the configuration of the bracket 134 is not limited to this.
[0039] Figure 3 FIG. 1 is a schematic diagram of another implementation of an expansion card. Figure 3In the embodiment shown, the normal directions N1' and N3' of the horizontal portion 134a' and the folded edge 134c' may be parallel to each other, wherein the horizontal portion 134a' and the folded edge 134c' are not on the same plane, and the normal direction N2' of the vertical portion 134b' is perpendicular to the normal directions N1' and N3' of the horizontal portion 134a' and the folded edge 134c'. In other embodiments not shown, the normal directions N1 and N3 of the horizontal portion 134a and the folded edge 134c may be parallel to each other, and the horizontal portion 134a and the folded edge 134c may be on the same plane.
[0040] Please continue to refer to Figure 1 and Figure 2 Specifically, there is a 2-3 mm gap between the avoidance groove 124 and the side wall 112 of the present embodiment. In other words, the avoidance groove 124 is retracted 2-3 mm from the edge 121b of the main board body 121 toward the inside of the main board body 121, and the shape of the avoidance groove 124 can be designed according to actual needs, such as a rectangle or a polygon, and is not limited to Figure 1 The shapes shown are limited.
[0041] When the expansion card 130 is assembled to the slot 122 of the mainboard 120, the card body 132 is inserted into the slot 122, and the bracket 134 is locked to the side wall 112, so as to stabilize the insertion of the card body 132 and the slot 122 while allowing the bracket 134 to provide support for the card body 132 to prevent the card body 132 from deforming.
[0042] During the assembly process, since the avoidance groove 124 is provided at the edge 121b of the main body 121 of the main board 120, and there is a gap of 2 to 3 mm between the avoidance groove 124 and the side wall 112, when the assembler inserts the card body 132 of the expansion card 130 into the slot 122, the tolerance for the insertion angle of the expansion card 130 is greater than that in the case where the avoidance groove 124 is not provided. The assembler only needs to pay attention to aligning the card body 132 of the expansion card 130 with the slot 122, and the vertical portion 134b of the bracket 134 of the expansion card 130 is partially inserted into the avoidance groove 124 without hitting the main body 121 of the main board 120 or the side wall 112 of the chassis 110.
[0043] As a result, the assembler does not need to worry about the collision between the vertical portion 134 b of the bracket 134 of the expansion card 130 and the mainboard body 121 or the side wall 112 of the chassis 110 , so the assembly can be performed at a larger angle and faster speed.
[0044] To sum up, in the electronic device of the present invention, an avoidance groove is provided at the edge of the mainboard, wherein the position of the avoidance groove corresponds to the position of the slot. Therefore, the assembler can insert the expansion card into the slot within a larger angle range and can simultaneously avoid the situation where the bracket of the expansion card collides with the side wall of the chassis or the edge of the mainboard. Therefore, it is convenient for the assembler to assemble.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
