Description

Technical Field

[0001] This application belongs to the field of electronic equipment, and specifically relates to an electronic device. Background Technology

[0002] With the development of technology, electronic devices have become increasingly widely used. They can be used to take pictures, watch videos, and communicate remotely. Furthermore, to unlock these devices, fingerprint recognition modules are often installed. These modules can be installed under the display screen, on the back of the device's casing, or on the side. However, as users have become more familiar with the design, installing the fingerprint recognition module on the side of the device's casing has become more popular.

[0003] In related technologies, when a fingerprint recognition module is installed on the side of an electronic device, the fingerprint recognition body of the module is locked to the side of the housing using multiple locking devices. However, this arrangement results in the locking devices occupying a significant amount of space within the housing, affecting the efficient use of internal space in the electronic device. Utility Model Content

[0004] The purpose of this application is to provide an electronic device that solves the problem that locking components occupy too much space in the housing, affecting the space utilization rate inside the electronic device's housing.

[0005] This application provides an electronic device, which includes: a housing and a fingerprint recognition module;

[0006] The fingerprint recognition module includes a fingerprint recognition body, a first support piece, and a single locking member. The first support piece is connected to the fingerprint recognition body. The housing is provided with a mounting groove. The fingerprint recognition body is mounted in the mounting groove. The first support piece is located in the mounting groove. The locking member is fixed to the groove wall of the mounting groove, and the locking member cooperates with the first support piece to fix the first support piece.

[0007] The fingerprint recognition body has a skirt on its side wall, which extends along the circumferential direction of the fingerprint recognition body. The mounting groove has a snap-fit ​​groove on its wall, and the skirt is located in the snap-fit ​​groove.

[0008] In this embodiment, since the first support piece is connected to the fingerprint recognition body, it provides support for the fingerprint recognition body. Because the housing has a mounting groove, the fingerprint recognition body is mounted in the mounting groove, the first support piece is located within the groove, and a locking member is fixed to the groove wall. The locking member engages with the first support piece, thus securing the first support piece, which in turn fixes the fingerprint recognition body in place. Because the sidewall of the fingerprint recognition body has a skirt extending circumferentially, and the groove wall of the mounting groove has a snap-fit ​​groove, with the skirt located within the snap-fit ​​groove, the skirt effectively further secures the fingerprint recognition body. In other words, in this embodiment, the locking member cooperates with the first support piece to fix the fingerprint recognition body, and the skirt on the side wall of the fingerprint recognition body engages with the snap-fit ​​groove on the housing, thereby fixing the fingerprint recognition body again. This is equivalent to fixing the fingerprint recognition body simultaneously through the skirt and the locking member, ensuring that the fingerprint recognition body is fixed relatively stably. Furthermore, by setting the skirt, the number of locking members can be reduced, avoiding the problem of low internal space utilization caused by excessive use of locking members. In other words, in this embodiment, by setting a skirt on the side wall of the fingerprint recognition body, the internal space utilization of the housing can be effectively improved.

[0020] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] Before explaining the electronic device provided in the embodiments of this application, the application scenario of the electronic device provided in the embodiments of this application will be specifically described: In related technologies, the side of the housing of an electronic device is provided with a mounting groove. The fingerprint recognition module includes a fingerprint recognition body, which is connected to a supporting steel plate. The supporting steel plate is located in the housing and is provided with multiple hooks. When it is necessary to fix the fingerprint recognition module, multiple locking elements lock multiple hooks, that is, one locking element locks one hook, so that the fingerprint recognition module is fixed. However, in this way, multiple locking elements occupy a lot of space in the housing, which leads to the compression of the space of other components inside the housing, which is not conducive to the arrangement of other components, and thus reduces the space utilization rate of the internal space of the electronic device housing.

[0022] like Figures 1 to 7 As shown, the electronic device includes a housing 10 and a fingerprint recognition module 20.

[0023] The fingerprint recognition module 20 includes a fingerprint recognition body 21, a first support piece 22, and a single locking member 23. The first support piece 22 is connected to the fingerprint recognition body 21. The housing 10 is provided with a mounting groove 101. The fingerprint recognition body 21 is installed in the mounting groove 101. The first support piece 22 is located in the mounting groove 101. The locking member 23 is fixed to the groove wall of the mounting groove 101, and the locking member 23 cooperates with the first support piece 22 to fix the first support piece 22. The side wall of the fingerprint recognition body 21 is provided with a skirt 211, which extends along the circumferential direction of the fingerprint recognition body 21. The groove wall of the mounting groove 101 is provided with a snap-fit ​​groove, and the skirt 211 is located in the snap-fit ​​groove.

[0024] In this embodiment, since the first support piece 22 is connected to the fingerprint recognition body 21, it can support the fingerprint recognition body 21. Because the housing 10 has a mounting groove 101, the fingerprint recognition body 21 is mounted in the mounting groove 101. The first support piece 22 is located in the mounting groove 101, and the locking member 23 is fixed to the groove wall of the mounting groove 101. The locking member 23 cooperates with the first support piece 22, thus fixing the first support piece 22, which in turn fixes the fingerprint recognition body 21. Since the side wall of the fingerprint recognition body 21 has a skirt 211 extending along its circumferential direction, and the groove wall of the mounting groove 101 has a snap-fit ​​groove, the skirt 211 is located in the snap-fit ​​groove. Therefore, the skirt 211 on the fingerprint recognition body 21 effectively further fixes the fingerprint recognition body 21. In other words, in this embodiment, the locking member 23 cooperates with the first support piece 22 to fix the fingerprint recognition body 21, and the skirt 211 on the side wall of the fingerprint recognition body 21 engages with the snap-fit ​​groove on the housing 10, thereby fixing the fingerprint recognition body 21 again. This is equivalent to fixing the fingerprint recognition body 21 simultaneously through the skirt 211 and the locking member 23, ensuring that the fingerprint recognition body 21 is fixed relatively stably. Furthermore, by setting the skirt 211, the number of locking members 23 can be reduced, avoiding the problem of low internal space utilization of the housing 10 caused by excessive use of locking members 23. In other words, by setting the skirt 211 on the side wall of the fingerprint recognition body 21, the internal space utilization of the housing 10 can be effectively improved.

[0025] It should be noted that, in this embodiment, the fingerprint recognition body 21 may include a fingerprint recognition chip, which can be packaged using LGA packaging technology, thus the fingerprint recognition body 21 is essentially a packaged fingerprint recognition chip. Furthermore, the fingerprint recognition body 21 includes a contact surface and a connecting surface facing away from each other. The contact surface is used for the user's finger to press or touch, enabling the fingerprint recognition body 21 to recognize the user's fingerprint. The connecting surface connects to a first support piece 22, which effectively supports the fingerprint recognition body 21, ensuring that it is not easily deformed when pressed and remains relatively stable. The sidewall of the fingerprint recognition body 21 is the surface between the contact surface and the connecting surface.

[0026] In addition, in this embodiment, the first support piece 22 can be a steel sheet, and the thickness of the first support piece 22 can be relatively thick, thereby ensuring that the first support piece 22 has a good supporting effect on the fingerprint recognition body 21. Of course, the first support piece 22 can also be formed of other materials, for example, the first support piece 22 can be formed of an alloy. In this embodiment, it is not limited in this respect. In addition, the thickness of the first support piece 22 can be set according to actual needs, for example, the thickness of the first support piece 22 is 2 mm, for another example, the thickness of the first support piece 22 is 3 mm, for another example, the thickness of the first support piece 22 is 1 mm. In this embodiment, it is not limited in this respect.

[0027] Furthermore, in this embodiment, the skirt 211 may extend circumferentially along the fingerprint recognition body 21, and the skirt 211 may only be provided on a portion of the sidewalls of the fingerprint recognition body 21, which is equivalent to the skirt 211 not completely surrounding the fingerprint recognition body 21 circumferentially; of course, the skirt 211 may also completely surround the fingerprint recognition body 21 circumferentially. This embodiment does not limit the scope of the embodiment.

[0028] In addition, in this embodiment, the skirt 211 and the fingerprint recognition body 21 can be an integral structure, that is, when the fingerprint recognition chip is packaged by LGA packaging process to form the fingerprint recognition body 21, the skirt 211 can be formed directly.

[0029] In addition, in this embodiment, the size of the card slot along the direction from the fingerprint recognition body 21 to the first support piece 22 can be larger than the size of the skirt 211. This ensures, on the one hand, that the card slot fixes the fingerprint recognition body 21 and prevents the fingerprint recognition body 21 from detaching from the housing 10. On the other hand, it ensures that the fingerprint recognition body 21 can move when the user presses it, thus ensuring that the fingerprint recognition body 21 can be pressed.

[0030] In addition, in some embodiments, the surface of the first support piece 22 facing away from the fingerprint recognition body 21 may be provided with an anti-collision protrusion 221, and the anti-collision protrusion 221 extends in a direction away from the first support piece 22.

[0031] Because the first support piece 22 has an anti-collision protrusion 221 on its surface opposite to the fingerprint recognition body 21, after the fingerprint recognition body 21 and the first support piece 22 are installed on the housing 10, once the user's finger presses the fingerprint recognition body 21 at the position corresponding to the anti-collision protrusion 221, the fingerprint recognition body 21 can be moved. The presence of the anti-collision protrusion 221 ensures that when the user presses the fingerprint recognition body 21, the anti-collision protrusion 221 moves with the first support piece 22 and abuts against the housing 10, thereby preventing the housing 10 from moving the anti-collision protrusion 221 and thus preventing the fingerprint recognition body 21 from moving continuously, avoiding excessive pressure on the fingerprint recognition body 21. In other words, by providing the anti-collision protrusion 221 on the surface of the first support piece 22 opposite to the fingerprint recognition body 21, excessive pressure on the fingerprint recognition body 21 can be effectively prevented when it is pressed.

[0032] It should be noted that the number of anti-collision protrusions 221 can be set according to actual needs. For example, the number of anti-collision protrusions 221 can be one, or for example, the number of anti-collision protrusions 221 can be two. In this regard, the embodiments of this application do not limit it. In addition, when there are multiple anti-collision protrusions 221, the multiple anti-collision protrusions 221 can be distributed at intervals.

[0033] Furthermore, in this embodiment, the shape of the anti-collision protrusion 221 can be set according to actual needs. For example, the anti-collision protrusion 221 can be columnar, or it can be strip-shaped. This embodiment does not limit the shape of the anti-collision protrusion 221.

[0034] Furthermore, in this embodiment, the anti-collision protrusion 221 can be integrally formed with the first support piece 22, resulting in higher overall strength of the first support piece 22 and the anti-collision protrusion 221. Of course, the anti-collision protrusion 221 can also be connected to the surface of the first support piece 22 facing away from the fingerprint recognition body 21 in other ways. For example, the anti-collision protrusion 221 can be welded to the surface of the first support piece 22 facing away from the fingerprint recognition body 21, or, for another example, the anti-collision protrusion 221 can be connected to the surface of the first support piece 22 facing away from the fingerprint recognition body 21 via a connector. This embodiment does not limit the specific connection methods described herein. Connectors include, but are not limited to, bolts, pins, etc.

[0035] In addition, in some embodiments, a first hook 222 is provided on the first support piece 22, and the first hook 222 abuts against the locking member 23 so that the locking member 23 cooperates with the first support piece 22.

[0036] Because the first support piece 22 is provided with a first hook 222, after the first support piece 22 is placed in the mounting groove 101 on the housing 10, the first hook 222 can abut against the locking member 23, thereby locking the first hook 222 and ensuring that the locking member 23 cooperates with the first support piece 22, thus fixing the first support piece 22. That is, by providing the first hook 222 on the first support piece 22, it is convenient for the locking member 23 to cooperate with the first support piece 22.

[0037] Furthermore, in this embodiment, the first hook 222 can be integrally formed with the first support piece 22, resulting in higher overall strength of the first support piece 22 and the first hook 222. Of course, the first hook 222 can also be connected to the first support piece 22 in other ways, such as welding it to the first support piece 22, or connecting it to the first support piece 22 via a connector. This embodiment does not limit the specific connection methods described herein. Connectors include, but are not limited to, bolts and pins.

[0038] It should be noted that, along the direction from the fingerprint recognition body 21 to the first support piece 22, the locking member 23 may have a first side and a second side, with the first side closer to the fingerprint recognition body 21 and the second side farther away from the fingerprint recognition body 21. The first hook 222 may be located on the second side of the locking member 23. Thus, when the fingerprint recognition body 21 detaches from the housing 10, the fingerprint recognition body 21 drives the first support piece 22 to move, and the first support piece 22 drives the first hook 222 to move. Therefore, the locking member 23 can block the first hook 222, preventing the fingerprint recognition body 21 from detaching from the housing 10. Specifically, when the fingerprint recognition body 21 is pressed, the fingerprint recognition body 21 moves along the direction from the first side to the second side of the locking member 23, causing the first hook 222 to move along the same direction. Thus, the locking member 23 will not affect the movement of the first hook 222, ensuring that the fingerprint recognition body 21 can be pressed.

[0039] In addition, in this embodiment of the application, a fixing groove may be provided on the groove wall of the mounting groove 101, and some locking members 23 are embedded in the fixing groove. In addition, some locking members 23 abut against the first hook 222.

[0040] In some embodiments, the fingerprint recognition module 20 may also include a first circuit board 24; a portion of the first circuit board 24 is located between the fingerprint recognition body 21 and the first support piece 22, and a connector 25 is provided on another portion of the first circuit board 24; a mounting hole 102 is provided inside the housing 10, the mounting hole 102 is misaligned with the mounting groove 101, and the mounting hole 102 communicates with the mounting groove 101, and the connector 25 is installed in the mounting hole 102; a flexible member 30 is provided in the housing 10, and the flexible member 30 seals the mounting hole 102.

[0041] Since part of the first circuit board 24 is located between the fingerprint recognition body 21 and the first support piece 22, and another part of the first circuit board 24 is provided with a connector 25, and the housing 10 has a mounting hole 102 inside, which is misaligned with the mounting groove 101 and communicates with it, when the fingerprint recognition module 20 is installed on the housing 10, the first circuit board 24 can be stretched so that the connector 25 is installed in the mounting hole 102, thereby allowing the connector 25 to be connected to other components inside the housing 10. In addition, a flexible member 30 is provided in the housing 10, which seals the mounting hole 102, ensuring that liquid outside the housing 10 does not flow into the housing 10 from the mounting hole 102, thus preventing the internal components of the housing 10 from being affected by liquid. In other words, by providing the first circuit board 24, it is convenient for the user to transmit signals to the components connected to the connector 25 inside the housing 10 through the connector 25 after pressing the fingerprint recognition body 21.

[0042] In addition, in this embodiment, the flexible member 30 can be a silicone plug. Of course, the flexible member 30 can also be other types, such as foam. This embodiment does not limit the specific type of flexible member.

[0043] In addition, in this embodiment, the connector 25 can pass through the mounting hole 102 and adhesive can be applied to the mounting hole 102 to waterproof the housing 10, preventing liquid from entering the housing 10 through the mounting hole 102 and causing damage to the devices inside the housing 10.

[0044] It should be noted that the electronic device may also include a motherboard, which is located in the housing 10. The connector 25 is connected to the motherboard, that is, the connector 25 can be connected to the connector 25 on the motherboard. Thus, when the fingerprint recognition body 21 is pressed with a protective cover, the fingerprint recognition body 21 can transmit the pressing signal to the first circuit board 24, and the first circuit board 24 transmits the signal to the motherboard through the connector 25.

[0045] It should also be noted that, in the embodiments of this application, the first circuit board 24 can be a flexible printed circuit (FPC).

[0046] In addition, in some embodiments, the first support piece 22 is provided with an anti-collision protrusion 221 on the surface away from the fingerprint recognition body 21, the flexible member 30 extends to the outside of the mounting hole 102, and the anti-collision protrusion 221 and the flexible member 30 are positioned opposite each other in the direction from the inside to the outside of the housing 10, and there is a gap between the anti-collision protrusion 221 and the flexible member 30.

[0047] Since the flexible member 30 extends to the outside of the mounting hole 102, and the anti-collision protrusion 221 and the flexible member 30 are positioned opposite each other in the direction from the inside to the outside of the housing 10, when the user presses the fingerprint recognition body 21 at the position opposite the anti-collision protrusion 221, the fingerprint recognition body 21 will be pressed and moved. This causes the fingerprint recognition body 21 to move the first support piece 22, which in turn moves the anti-collision protrusion 221. After the anti-collision protrusion 221 moves, it abuts against the flexible member 30. The flexible member 30 then prevents the first support piece 22 from moving further, thereby preventing the fingerprint recognition body 21 from moving further and avoiding excessive pressure on the fingerprint recognition body 21. Furthermore, the contact between the flexible member 30 and the anti-collision protrusion 221 also ensures that the reaction force provided by the flexible member 30 to the anti-collision protrusion 221 is transmitted to the user's finger during the user's pressing of the fingerprint recognition body 21, making the user feel more comfortable. By setting the flexible part 30 to extend to the outside of the mounting hole 102, and the anti-collision protrusion 221 to be positioned opposite the flexible part 30, the fingerprint recognition body 21 can be prevented from being excessively pressed when the user presses it. The flexible part 30 can also block and buffer the anti-collision protrusion 221, ensuring that the user can press the fingerprint recognition body 21 more comfortably.

[0048] In some embodiments, the fingerprint recognition module 20 further includes a dome switch 26, a second circuit board 27, and a second support plate 28; the second circuit board 27 has a first surface and a second surface facing away from each other, the dome switch 26 is disposed on the first surface, and the second support plate 28 is connected to the second surface; the bottom of the mounting groove 101 is provided with a through hole 103, which has a first side and a second side facing away from each other along the direction from the inside to the outside of the housing 10, the first support plate 22 is located on the first side, and the dome switch 26, the circuit board, and the second support plate 28 are located on the second side; a transmission member 29 is provided in the through hole 103, one end of the transmission member 29 abuts against the first support plate 22, and the other end of the transmission member 29 abuts against the dome switch 26.

[0049] Since the dome switch 26 is disposed on the first surface and the second support plate 28 is connected to the second surface, the second support plate 28 can support the second circuit board 27. Because the bottom of the mounting groove 101 has a through hole 103, and a transmission member 29 is disposed in the through hole 103, with one end of the transmission member 29 abutting against the first support plate 22 and the other end abutting against the dome switch 26, when the user presses the fingerprint recognition body 21, the fingerprint recognition body 21 can drive the first support plate 22 to move. This allows the first support plate 22 to exert force on the transmission member 29, which in turn exerts force on the dome switch 26. Consequently, the dome switch 26 can transmit a signal to the second circuit board 27, ensuring that the second circuit board 27 receives the signal. In other words, by setting the transmission member 29, when the user presses the fingerprint recognition body 21, it is ensured that the dome switch 26 is pressed, thereby transmitting the signal to the second circuit board 27.

[0050] It should be noted that, in this embodiment of the application, the second circuit board 27 can be a flexible printed circuit (FPC).

[0051] In addition, in this embodiment, the second support sheet 28 can be a steel sheet, and the thickness of the second support sheet 28 can be relatively thick, thereby ensuring that the second support sheet 28 has a good supporting effect on the fingerprint recognition body 21. Of course, the second support sheet 28 can also be formed of other materials, for example, the second support sheet 28 can be formed of an alloy. In this embodiment, it is not limited in this respect. In addition, the thickness of the second support sheet 28 can be set according to actual needs, for example, the thickness of the second support sheet 28 is 1 mm, for another example, the thickness of the second support sheet 28 is 0.5 mm, for another example, the thickness of the second support sheet 28 is 1.5 mm. In this embodiment, it is not limited in this respect.

[0052] In addition, in this embodiment, the dome switch 26 can be directly soldered onto the second circuit board 27, and in this embodiment, the transmission component 29 can directly abut against the dome switch 26, thereby eliminating the need for the bracket for mounting the dome switch 26 and further saving space inside the housing 10.

[0053] In addition, in some embodiments, a second hook 281 is provided on the second support piece 28, and a snap-fit ​​hole 104 is provided in the housing 10. The second hook 281 snaps into the snap-fit ​​hole 104 to fix the second support piece 28.

[0054] Since the second support piece 28 is provided with a second hook 281 and the housing 10 is provided with a snap-fit ​​hole 104, when the second support piece 28 is installed in the housing 10, the second hook 281 can be directly snapped into the snap-fit ​​hole 104, thereby fixing the second support piece 28. That is, by providing the second hook 281, it is easy to fix the second support piece 28 in the housing 10, thus facilitating the installation of the second support piece 28.

[0055] It should be noted that, in this embodiment, the second support piece 28 can also be bonded to the housing 10 with adhesive, thereby fixing the second support piece 28. Alternatively, in this embodiment, the second hook 281 on the second support piece 28 can be engaged with the snap-fit ​​hole 104 on the housing 10, and the second support piece 28 can be bonded to the housing 10 with adhesive, ensuring that the second support piece 28 is firmly fixed.

[0056] Furthermore, in this embodiment, the second hook 281 can be integrally formed with the second support piece 28, resulting in higher overall strength of the second support piece 28 and the second hook 281. Of course, the second hook 281 can also be connected to the second support piece 28 in other ways, such as welding it to the second support piece 28, or connecting it to the second support piece 28 via a connector. This embodiment does not limit the specific connection methods described herein. Connectors include, but are not limited to, bolts, pins, etc.

[0057] Furthermore, in this embodiment, the number of second hooks 281 can be set according to actual needs. For example, if there are two second hooks 281, they can be spaced apart. Or, for example, if there are four second hooks 281. The specific number of second hooks 281 is not limited in this embodiment.

[0058] In addition, in some embodiments, the transmission member 29 includes a first transmission part 291 and a second transmission part 292, the first transmission part 291 and the second transmission part 292 are connected, the first transmission part 291 abuts against the first support piece 22, and the second transmission part 292 abuts against the dome piece 26; the first transmission part 291 is a flexible transmission part, and the second transmission part 292 is a rigid transmission part.

[0059] Since the first transmission part 291 abuts against the first support piece 22 and the second transmission part 292 abuts against the dome switch 26, when the user presses the fingerprint recognition body 21, the fingerprint recognition body 21 can transmit force to the first transmission part 291 through the first support piece 22. This causes the first transmission part 291 to drive the second transmission part 292 to move, and the second transmission part 292 applies force to the dome switch 26, causing the dome switch 26 to be stressed and thus transmit a signal to the second circuit board 27. Because the first transmission part 291 is a flexible transmission part and the second transmission part 292 is a rigid transmission part, when the user presses the fingerprint recognition body 21, the first support piece 22 applies force to the first transmission part 291. The flexibility of the first transmission part 291 provides a certain buffering effect, thus preventing the transmission part 29 from rigidly pressing against the dome switch 26, which could lead to the dome switch 26 easily failing. By setting the first transmission part 291 as a flexible transmission part and the second transmission part 292 as a rigid transmission part, the problem of the hot dome 26 being prone to failure can be avoided while ensuring that the hot dome 26 is pressed.

[0060] It should be noted that, in the embodiments of this application, the first transmission part 291 can be soft rubber, and the second transmission part 292 can be a transmission rod.

[0061] In addition, in this embodiment, a buffer can also be provided at the end of the second transmission part 292 away from the first transmission part 291. The buffer abuts against the dome switch 26, which can further prevent the transmission part 29 from hard-pressing against the dome switch 26, thus avoiding the problem of the dome switch 26 being prone to failure. The buffer can be silicone, foam, etc.

[0062] In addition, in some embodiments, the second transmission part 292 is provided with a slot 2921, and the first transmission part 291 is provided with a receiving platform 2911, which is embedded in the slot 2921.

[0063] Since the second transmission part 292 is provided with a slot 2921 and the first transmission part 291 is provided with a locking platform 2911, when it is necessary to connect the first transmission part 291 and the second transmission part 292, the locking platform 2911 on the first transmission part 291 can be directly locked into the slot 2921 on the second transmission part 292, thereby facilitating the connection between the first transmission part 291 and the second transmission part 292.

[0064] It should be noted that, in the embodiments of this application, the first transmission part 291 and the second transmission part 292 can also be injection molded into an integral structure through a double injection molding process, which can effectively avoid the problem of easy separation between the first transmission part 291 and the second transmission part 292.

[0065] In some embodiments, a sealing ring 293 is fitted onto the transmission component 29, and the sealing ring 293 abuts against the wall of the through hole 103. By providing the sealing ring 293, the sealing ring 293 can effectively seal the gap between the transmission component 29 and the through hole 103, effectively preventing liquid from flowing from the through hole 103 to the dome switch 26 and causing damage to the dome switch 26. That is, by providing the sealing ring 293, the waterproofness of the housing 10 can be effectively improved, thereby protecting the dome switch 26 and preventing the dome switch 26 from being damaged by contact with liquid.

[0066] It should be noted that the sealing ring 293 can be made of silicone, i.e., the sealing ring 293 is a silicone ring. Of course, the sealing ring 293 can also be made of rubber, i.e., the sealing ring 293 is a rubber ring. The specific material of the sealing ring 293 is not limited in this embodiment.

[0067] In addition, in this embodiment, the sealing ring 293 can be injection molded onto the transmission component 29 using a liquid injection molding process, thereby effectively avoiding the problem of the sealing ring 293 easily separating from the transmission component 29. Furthermore, when the transmission component 29 includes a first transmission part 291 and a second transmission part 292, the sealing ring 293 can be fitted onto the second transmission part 292.

[0068] In addition, in this embodiment, when assembling the fingerprint recognition device on the housing 10, the assembly process can be as follows: First, the dome switch 26, the second circuit board 27, and the second support plate 28 are installed in the housing 10, and the second hook 281 on the second support plate 28 is engaged in the engagement hole 104 on the housing 10, so that the second support plate 28 is fixed. Then, the transmission member 29 is passed through the through hole 103 on the housing 10, and the transmission member 29 is in contact with the overload plate. Then, the first circuit board 24 is tilted, so that the connector 25 on the first circuit board 24 is moved to the mounting hole 102, and the connector 25 is passed through the mounting hole 102. Then, the fingerprint recognition body 21 is embedded in the mounting groove 101, and the skirt 211 on the fingerprint recognition body 21 cooperates with the engagement groove, so that the first hook 222 on the first support plate 22 cooperates with the locking member 23. Finally, glue can be applied to the connector 25, and the mounting hole 102 is sealed by the flexible member 30.

[0069] It should be noted that, in the embodiments of this application, electronic devices include, but are not limited to, controllers, smart devices, terminal products, etc., wherein smart devices include, for example, smartphones, smart TVs, smart speakers, smart robots, VR devices, AR devices, XR devices, etc., and terminal products include, for example, personal computers, tablet computers, etc.

[0070] In this embodiment, since the first support piece 22 is connected to the fingerprint recognition body 21, it can support the fingerprint recognition body 21. Because the housing 10 has a mounting groove 101, the fingerprint recognition body 21 is mounted in the mounting groove 101. The first support piece 22 is located in the mounting groove 101, and the locking member 23 is fixed to the groove wall of the mounting groove 101. The locking member 23 cooperates with the first support piece 22, thus fixing the first support piece 22, which in turn fixes the fingerprint recognition body 21. Since the side wall of the fingerprint recognition body 21 has a skirt 211 extending along its circumferential direction, and the groove wall of the mounting groove 101 has a snap-fit ​​groove, the skirt 211 is located in the snap-fit ​​groove. Therefore, the skirt 211 on the fingerprint recognition body 21 effectively further fixes the fingerprint recognition body 21. In other words, in this embodiment, the locking member 23 cooperates with the first support piece 22 to fix the fingerprint recognition body 21, and the skirt 211 on the side wall of the fingerprint recognition body 21 engages with the snap-fit ​​groove on the housing 10, thereby fixing the fingerprint recognition body 21 again. This is equivalent to fixing the fingerprint recognition body 21 simultaneously through the skirt 211 and the locking member 23, ensuring that the fingerprint recognition body 21 is fixed relatively stably. Furthermore, by setting the skirt 211, the number of locking members 23 can be reduced, avoiding the problem of low internal space utilization of the housing 10 caused by excessive use of locking members 23. In other words, by setting the skirt 211 on the side wall of the fingerprint recognition body 21, the internal space utilization of the housing 10 can be effectively improved.
