Description

Mainboard module

Technical Field

The invention relates to a mainboard module.

Background

Because the main circuit board of the computer has limited functions, in order to improve the functions of the computer, a connector must be arranged on the main circuit board to connect the expansion card module. To increase the stability of the card module, a fixing device is often used, which is fixed on the card module, and the fixing device is fastened to the computer case to fix the position relationship between the card module and the main circuit board. However, as the card module is miniaturized, and the arrangement positions of various components on the main circuit board are changed along with the reduction of the volume of the computer, the fixing manner by which the fixing device is fastened to the computer casing is limited.

In view of the above-mentioned drawbacks of the prior art, an object of the present invention is to provide a motherboard module, which can mount a circuit board on a motherboard without using additional tools and does not occupy the space occupied by peripheral components during the mounting process.

According to an embodiment of the present invention, the motherboard module includes a motherboard, a first fixing structure, a circuit board, and a fastening structure. The main board is provided with a slot. The first fixing structure is arranged on the mainboard. The circuit board has an electrical connection portion. The electrical connection portion of the circuit board is configured to be removably coupled to the slot of the motherboard. The clamping structure is connected with the circuit board, is provided with an opening and a clamping space, and comprises a clamping stop piece positioned in the clamping space. The engaging space of the engaging structure is configured to accommodate the first fixing structure inserted from the opening.

In one or more embodiments of the present invention, the motherboard module further includes a housing. The shell is arranged on the main board and comprises a side wall. The first fixing structure protrudes from a sidewall of the housing. The clamping structure is also provided with a long slot hole. The long slotted hole and the opening of the clamping structure are respectively arranged on two surfaces connected on the clamping structure and connected with the opening. When the electrical connection portion of the circuit board is coupled to the slot of the main board, the first fixing structure penetrates through the long slot of the clamping structure and is clamped between the clamping stop piece of the clamping structure and the tail end of the clamping space far away from the opening.

In one or more embodiments of the present invention, the first fixing structure is a cylinder. The column body comprises a head part and a neck part which are connected. The neck of the column is connected with the side wall of the shell. The head of the column body is configured to penetrate the long slot hole of the clamping structure in a sliding way and is positioned in the clamping space, and the head is clamped between the clamping stop piece of the clamping structure and the tail end of the clamping space.

In one or more embodiments of the present invention, the motherboard module further includes a second fixing structure. The second fixing structure protrudes from a sidewall of the housing. When the electric connection part of the circuit board is coupled with the slot of the mainboard, the second fixing structure penetrates through the long slot hole of the clamping structure to be partially positioned in the clamping space, and the clamping stop piece of the clamping structure is positioned on one side, opposite to the first fixing structure.

In one or more embodiments of the present invention, the locking member of the engaging structure includes a resilient arm and a protrusion. One end of the elastic arm of the retainer is connected to the projection. The other end of the elastic arm of the clamping fastener is connected to a part of the inner wall of the clamping structure forming the clamping space.

In one or more embodiments of the present invention, the engaging structure further includes an elastic wall. The elastic wall of the engaging structure forms a part of the inner wall of the engaging space. The clamping stop piece of the clamping structure protrudes from the elastic wall in the clamping space.

In one or more embodiments of the present invention, the engaging structure has two slots. In the clamping structure, an elastic wall is formed at a position between the two slots.

In one or more embodiments of the present invention, the main board module further includes a handle. The handle is connected with one side of the clamping structure opposite to the opening.

In one or more embodiments of the present invention, the motherboard module further includes an expansion card. The expansion card is inserted on the circuit board.

In summary, the invention is connected to the fastening structure of the circuit board by fastening through the fixing structure on the motherboard. Therefore, the circuit board can be installed on the mainboard without using extra tools, and the use space of peripheral parts is not occupied in the installation process. Therefore, the fixing structure and the engaging structure of the present embodiment can minimize the space required for mounting the circuit board on the motherboard, so as to increase the flexibility of applying the circuit board to different systems, and enable the user to operate the circuit board by only using hands, and simultaneously, the circuit board can be stably fixed on the motherboard by the fixing structure and the engaging structure. In addition, the handle of the embodiment is connected with one side of the clamping structure opposite to the opening. Therefore, when the connection between the circuit board connected to the engaging structure and the main board is to be released, the user only needs to move the handle in the direction away from the main board, so as to release the engaging structure from the fixing structure disposed on the main board, and further pull out the electrical connection portion of the circuit board from the slot of the main board, so that the circuit board is separated from the main board.

Please refer to fig. 1A to fig. 2C. Fig. 1A and 1B respectively show a perspective view of a motherboard module 1 according to an embodiment of the invention. The electrical connection portion 140 of the circuit board 14 in fig. 1A is not coupled to the slot 100 of the motherboard 10, and the electrical connection portion 140 of the circuit board 14 in fig. 1B is coupled to the slot 100 of the motherboard 10. Fig. 2A to 2C respectively show a side view of the motherboard module 1 according to an embodiment of the invention, and the housing 11 is omitted, and only the first fixing structure 12A and the second fixing structure 12b are shown. As shown in the drawings, in the present embodiment, the motherboard module 1 includes a motherboard 10, a housing 11, a first fixing structure 12a, a second fixing structure 12b, a third fixing structure 18 (see fig. 1A), a circuit board 14, a female slot 142, an expansion card 15, a first engaging structure 16, a second engaging structure 19, a first handle 13, and a second handle 17. The structure, function, and connection between the components will be described in detail below.

As shown in fig. 1A, the main board 10 has a slot 100. The slot 100 of the motherboard 10 is configured to interface with other expansion cards along a first direction D1 perpendicular to the motherboard 10. The housing 11, the first fixing structure 12a and the second fixing structure 12b are disposed on the main board 10. In detail, the housing 11 includes a sidewall 110. The sidewalls 110 are substantially perpendicular to the main board 10. In some embodiments, the housing 11 is used to place an electronic device (not shown) such that the electronic device is located between the two sidewalls 110, but the disclosure is not limited thereto. For example, the electronic device includes a heat sink, a hard disk, or any other suitable device.

In addition, in the present embodiment, a direction substantially perpendicular to the sidewall 110 is defined as a second direction D2. The extending direction of the sidewall 110 is defined as a third direction D3. In some embodiments, the first direction D1, the second direction D2, and the third direction D3 intersect each other. In the present embodiment, the first direction D1, the second direction D2, and the third direction D3 are substantially orthogonal to each other.

As shown in fig. 1A, the first fixing structures 12a and the second fixing structures 12b respectively protrude from the side wall 110 of the housing 11 and are arranged along the first direction D1, but the disclosure is not limited thereto. In the present embodiment, the first fixing structure 12a is a cylinder and includes a first head 120a and a first neck 122a connected to each other. The first neck portion 122a of the first fixing structure 12a is connected to the sidewall 110 of the housing 11. In the present embodiment, the first neck portion 122A of the first fixing structure 12A has a first width W1 (see fig. 2A) along the third direction D3, and the first head 120a has a second width W2 (see fig. 2A) along the third direction D3. The second width W2 is greater than the first width W1. The structure and function of the second fixing structure 12b are substantially the same as those of the first fixing structure 12a, so that reference can be made to the above description for brevity. It is noted that the second fixing structure 12b is different from the first fixing structure 12a in that the second fixing structure 12b is closer to the main board 10 than the first fixing structure 12 a.

As shown in fig. 1A, the third fixing structure 18 is disposed on the main board 10, substantially protrudes away from the main board 10 along the first direction D1, and sequentially has a first fixing portion 180, a necking portion 182, and a second fixing portion 184 toward the main board 10. The necked-down portion 182 of the third fastening structure 18 is connected between the first fastening portion 180 and the second fastening portion 184. The first securing portion 180, the necked-down portion 182, and the second securing portion 184 of the third securing structure 18 have a third width W3, a fourth width W4, and a fifth width W5, respectively, in the radial direction (see fig. 3C). The fifth width W5 of the second anchor 184 of the third anchor structure 18 is substantially equal to the third width W3 of the first anchor 180 and is greater than the fourth width W4 of the necked-down portion 182.

In the present embodiment, the circuit board 14 has an electrical connection portion 140 (see fig. 1A). The mother socket 142 is fixed to the circuit board 14 and supports a solid state disk of pcie (peripheral Component Interconnect express) specification or sata (serial Advanced Technology attachment) specification, but the invention is not limited thereto. The electrical connection portion 140 of the circuit board 14 is configured to be pluggably coupled to the socket 100 of the motherboard 10 along the first direction D1. The expansion card 15 is plugged on the circuit board 14 to electrically connect to the motherboard 10 through the electrical connection portion 140 and the slot 100. In the present embodiment, the expansion card 15 is an m.2(Next Generation Form Factor, NGFF) solid state disk, but the present invention is not limited thereto. In some embodiments, any suitable expansion card may be used in the present invention.

Next, in the present embodiment, the structure and function of the first engaging structure 16 and the connection relationship with each component will be described in detail with reference to fig. 2A, 2B, and 2C. As shown in fig. 2A and fig. 2B, in the present embodiment, the first engaging structure 16 is connected to one end of the circuit board 14, has a first opening 160, a first engaging space 162, a first inner wall 163, a slotted hole 166 and an offset space 168, and includes a first locking member 164 located in the first engaging space 162.

In fig. 2A, the slot 166 and the first opening 160 of the first engaging structure 16 are respectively opened on two surfaces of the first engaging structure 16 connected to each other and connected to the first opening 160. The first inner wall 163 of the first engaging structure 16 surrounds the first engaging space 162. The first engaging space 162 is configured to accommodate the first fixing structure 12a and the second fixing structure 12b inserted from the first opening 160, and has a first end 162 a. The first end 162a of the first engaging space 162 is located at a side of the first locking member 164 away from the first opening 160.

In the present embodiment, the first locking piece 164 of the first engagement structure 16 includes an elastic arm 1640 and a protrusion 1642. The elastic arm 1640 of the first latch 164 extends in the first engaging space 162 and is substantially parallel to the first inner wall 163. In detail, the elastic arm 1640 has a first end portion 1644 and a second end portion 1646 away from the first opening 160 with respect to the first end portion 1644. The first end portion 1644 of the resilient arm 1640 is connected to a portion of the first inner wall 163 of the first snap fit structure 16. The second end 1646 of the spring arm 1640 is connected to the projection 1642. The protrusion 1642 of the first locking member 164 is adjacent to the first end 162a of the first engaging space 162 and configured to be engaged with the first fixing structure 12a accommodated in the first engaging space 162, so as to lock the first fixing structure 12a to the first end 162a of the first engaging space 162.

In the present embodiment, the relief space 168 of the first engaging structure 16 is located on a side of the first clamping space 162 opposite to the first clamping member 164, and is configured to accommodate at least a portion of the first clamping member 164 when the first clamping member 164 is pressed.

Please refer to fig. 2A. The electrical connections 140 of the circuit board 14 shown in fig. 2A are not coupled to the socket 100 of the motherboard 10. In the present embodiment, during the relative movement and approaching of the circuit board 14 and the main board 10, the first head 120a (see fig. 1A) of the first fixing structure 12a is slidably inserted into the slot 166 of the first engaging structure 16 through the first opening 160 to be located in the first engaging space 162, and is slid from the first opening 160 toward the first end 162a of the first engaging space 162. The first neck portion 122a (see fig. 1A) of the first fixing structure 12a is at least partially located outside the first engaging space 162.

With the aforementioned configuration, in the third direction D3, the slot 166 has a sixth width W6. The first width W1 of the first neck portion 122a of the first fastening structure 12a (see FIG. 1A) is substantially equal to or less than the sixth width W6 of the slotted hole. The second width W2 of the first head 120a (see FIG. 1A) of the first fastening structure 12a is greater than the sixth width W6 of the slotted aperture. Therefore, when the first head 120a of the first fixing structure 12a is located in the first engaging space 162, the first fixing structure 12a restricts the movement of the first engaging structure 16 in the second direction D2 and the third direction D3, and engages at least between the first opening 160 of the first engaging structure 16 and the protrusion 1642 of the first locking piece 164, thereby positioning the circuit board 14.

Next, please refer to fig. 2B. The electrical connection portion 140 of the circuit board 14 shown in fig. 2B is not coupled to the socket 100 of the motherboard 10. During the relative movement of the circuit board 14 and the main board 10, the second head 120b (see fig. 1A) of the second fixing structure 12b is slidably inserted into the slot 166 of the first engaging structure 16 via the first opening 160 to be located in the first engaging space 162, and moves from the first opening 160 toward the protrusion 1642 of the first latch 164. The second neck portion 122b (see fig. 1A) of the second fixing structure 12b is at least partially located outside the first engaging space 162. In the present embodiment, since the first fixing structure 12a and the second fixing structure 12b are disposed along the first direction D1, when the first fixing structure 12a and the second fixing structure 12b are both located in the first engaging space 162, the first engaging structure 16 only moves along the first direction D1, but does not rotate on the plane formed by the second direction D2 and the third direction D3, so as to stably move the circuit board 14 along the first direction D1 toward the motherboard 10.

Then, when the circuit board 14 and the main board 10 continue to move closer to each other, so that the first fixing structure 12a contacts the side of the protrusion 1642 of the first latch 164 close to the first opening 160, the first fixing structure 12a presses the protrusion 1642 of the first latch 164. Therefore, the protrusion 1642 is pressed by the first fixing structure 12a and is extruded out of the first engaging space 162 to the relief space 168, so that the first fixing structure 12a can overcome the interference of the protrusion 1642 on the structural configuration, and thus slide to the side of the protrusion 1642 away from the first opening 160 (see fig. 2C).

Next, please refer to fig. 2C. The electrical connection portion 140 (see fig. 2A and 2B) of the circuit board 14 in fig. 2C is coupled to the socket 100 of the motherboard 10. When the circuit board 14 and the motherboard 10 continue to move relatively close to each other, so that the electrical connection portion 140 of the circuit board 14 is inserted into the slot 100 of the motherboard 10, the first fixing structure 12a is engaged between the first engaging member 164 of the first engaging structure 16 and the first end 162a of the first engaging space 162. The protrusion 1642 is protruded into the first engaging space 162 by the elastic arm 1640 without being pressed by the first fixing structure 12 a. Therefore, when the first fixing structure 12a slides to the first end 162a of the first engaging space 162, the protrusion 1642 prevents the first fixing structure 12a from sliding away from the first end 162a of the first engaging space 162, so as to maintain the distance between the circuit board 14 and the motherboard 10, i.e., the distance between the electrical connection portion 140 and the slot 100, and ensure the connection between the electrical connection portion 140 and the slot 100.

In the present embodiment, when the electrical connection portion 140 of the circuit board 14 is coupled to the slot 100 of the motherboard 10, the second fixing structure 12b is located on a side of the first locking member 164 of the first engaging structure 16 opposite to the first fixing structure 12 a.

In this embodiment, the first handle 13 is connected to a side of the first engaging structure 16 opposite to the first opening 160. Thus, when the connection between the circuit board 14 and the main board 10 is to be released, the user only needs to move the first handle 13 in a direction away from the main board 10, and drive the first engaging structure 16 and the first fixing structure 12a and the second fixing structure 12b to move relatively, so that when the first fixing structure 12a contacts the side of the protrusion 1642 of the first locking piece 164 away from the first opening 160, the first fixing structure 12a will press the protrusion 1642 of the first locking piece 164. Therefore, the protrusion 1642 is pressed by the first fixing structure 12a and is extruded out of the first engaging space 162 to the receding space 168, so that the first fixing structure 12a can overcome the interference of the protrusion 1642 on the structural configuration, and slide to the side of the protrusion 1642 close to the first opening 160. By doing so, the locking relationship between the first locking structure 16 and the first fixing structure 12a is released, and the electrical connection portion 140 of the circuit board 14 can be pulled out from the slot 100 of the main board 10, so that the circuit board 14 is separated from the main board 10.

Next, please refer to fig. 3A and fig. 3B. Fig. 3A and fig. 3B are perspective views respectively illustrating partial structures of the main board module 1 according to an embodiment of the invention at different viewing angles. In addition, in order to understand the present disclosure, fig. 3A and 3B omit the partial female slot 142 and the expansion card 15 shown in fig. 1A and 1B.

In this embodiment, the structure and function of the second engaging structure 19 and the connection relationship with each component will be described in detail with reference to fig. 3A and 3B. As shown in fig. 3A and 3B, in the present embodiment, the second engaging structure 19 is connected to an end of the circuit board 14 opposite to the first engaging structure 16 (see fig. 2A to 2C), has a second opening 190, a second engaging space 192 and two slots 198, and includes a second locking member 194 (see fig. 3B) and an elastic wall 196 (see fig. 3A) located in the second engaging space 192.

In fig. 3A and 3B, the second engaging space 192 of the second engaging structure 19 is configured to receive the third fixing structure 18 inserted through the second opening 190 (see fig. 3C and 3D), and has a second end 192a (see fig. 3C and 3D). The second end 192a of the second engaging structure 19 is located at a side of the second locking member 194 away from the second opening 190. In the second engaging structure 19, an elastic wall 196 is formed at a portion between the two slots 198. In the present embodiment, the elastic wall 196 of the second engaging structure 19 forms a part of the second inner wall 193 (see fig. 3B) of the second engaging space 192. The second locking member 194 of the second engaging structure 19 protrudes from the elastic wall 196 into the second engaging space 192. The second locking piece 194 of the second engaging structure 19 is configured to engage with the necking portion 182 (see fig. 3C and 3D) of the third fixing structure 18 accommodated in the second engaging space 192.

Please refer to fig. 3C and fig. 3D. Fig. 3C and fig. 3D respectively show cross-sectional views of the motherboard module 1 along line 1A-1A in fig. 1A at different assembly stages according to an embodiment of the invention. In fig. 3C, the electrical connection portion 140 of the circuit board 14 is not coupled to the slot 100 of the motherboard 10 (see fig. 2B), and in fig. 3D, the electrical connection portion 140 of the circuit board 14 is coupled to the slot 100 of the motherboard 10 (see fig. 2C).

As shown in fig. 3C, in the present embodiment, while the circuit board 14 and the main board 10 move relatively close to each other, the third fixing structure 18 slides through the second opening 190 to be partially located in the second engaging space 192, and moves from the second opening 190 toward the second locking piece 194.

Therefore, the third fixing structure 18 restricts the second engaging structure 19 from moving in the second direction D2 and the third direction D3, and engages at least between the first opening 160 and the second locking member 194 of the first engaging structure 16, thereby positioning the circuit board 14. In the present embodiment, the third fixing structure 18 substantially protrudes away from the main board 10 along the first direction D1, so that the second engaging structure 19 sleeved thereon is restricted from moving in the first direction D1.

Then, when the circuit board 14 and the main board 10 continue to move relatively close to each other, so that the second fixing portion 184 of the third fixing structure 18 contacts a side of the second locking member 194 close to the second opening 190, the second fixing portion 184 presses the second locking member 194. Therefore, the second locking piece 194 is pressed by the second fixing portion 184, and further presses the elastic wall 196 of the second engaging structure 19. The elastic wall 196 is pressed and deformed to be recessed away from the second engaging space 192, and drives the second locking member 194 to be away from the second engaging space 192, so that the second fixing portion 184 of the third fixing structure 18 can overcome the interference of the second locking member 194 in the structural configuration, and thus slide to the side of the second locking member 194 away from the second opening 190.

Next, as shown in fig. 3D, when the circuit board 14 and the motherboard 10 continuously move closer to each other to couple the electrical connection portion 140 of the circuit board 14 with the slot 100 of the motherboard 10 (see fig. 2C), the second fixing portion 184 of the third fixing structure 18 is engaged between the second locking member 194 of the second engaging structure 19 and the second end 192a of the second engaging space 192, and the second locking member 194 of the second engaging structure 19 is engaged with the necking portion 182 of the third fixing structure 18.

Specifically, the second locking member 194 is protruded into the second engaging space 192 by the elastic wall 196 without being pressed by the second fixing portion 184. Therefore, when the second fixing portion 184 of the third fixing structure 18 slides to the second end 192a of the second engaging space 192, the second locking member 194 can prevent the second fixing portion 184 from sliding away from the second end 192a of the second engaging space 192. Further, the engagement between the second locking member 194 of the second engaging structure 19 and the necked portion 182 of the third fixing structure 18 also prevents the second engaging structure 19 from moving relative to the third fixing structure 18. Under the above configuration, the distance between the circuit board 14 and the motherboard 10 can be maintained, and further the distance between the electrical connection portion 140 and the slot 100 is maintained (see fig. 2C), so as to ensure the combination between the electrical connection portion 140 and the slot 100.

In the present embodiment, the second handle 17 is connected to the second engaging structure 19 on the side opposite to the second opening 190. The structure and function of the second handle 17 are substantially the same as those of the first handle 13, so that reference can be made to the above description, and the description thereof is omitted. Therefore, when the connection between the circuit board 14 and the main board 10 is to be released, the user only needs to move the second handle 17 in the direction away from the main board 10 and drive the second engaging structure 19 and the third fixing structure 18 to move relatively, so that when the second fixing portion 184 of the third fixing structure 18 contacts the side of the second locking member 194 away from the second opening 190, the second fixing portion 184 presses the second locking member 194. Therefore, the second locking member 194 is pressed by the second fixing portion 184 and is pressed away from the second engaging space 192, so that the second fixing portion 184 of the third fixing structure 18 can overcome the interference of the second locking member 194 in the structural configuration, and slide to the side of the second locking member 194 close to the second opening 190. By doing so, the locking relationship between the second engaging structure 19 and the fixing structure 18 is released, and the electrical connection portion 140 of the circuit board 14 can be pulled out from the slot 100 of the main board 10, so that the circuit board 14 is separated from the main board 10.

As apparent from the above detailed description of the embodiments of the present invention, the present disclosure utilizes the fixing structure on the motherboard to engage with the engaging structure of the circuit board. Therefore, the circuit board can be installed on the mainboard without using extra tools, and the use space of peripheral parts is not occupied in the installation process. Therefore, the fixing structure and the engaging structure of the present embodiment can minimize the space required for mounting the circuit board on the motherboard, thereby increasing the flexibility of applying the circuit board to different systems, allowing a user to operate the circuit board by only using hands, and simultaneously fixing the circuit board on the motherboard stably by the fixing structure and the engaging structure.

In addition, the handle of the embodiment is connected with one side of the clamping structure opposite to the opening. Therefore, when the connection between the circuit board connected to the engaging structure and the main board is to be released, the user only needs to move the handle in the direction away from the main board, so as to release the engaging structure from the fixing structure disposed on the main board, and further pull out the electrical connection portion of the circuit board from the slot of the main board, so that the circuit board is separated from the main board.

The foregoing features of the various embodiments may provide a better understanding of various aspects of the present invention by those of ordinary skill in the art. Those skilled in the art should appreciate that they may readily use the present disclosure as a basis for designing or modifying other processes and structures for carrying out the same purposes and/or achieving the same advantages of the embodiments introduced herein. It should also be realized by those skilled in the art that such equivalent constructions do not depart from the spirit and scope of the invention, and that they may make various changes, substitutions and alterations herein without departing from the spirit and scope of the invention.
