Description

Technical Field

[0001] The invention relates to the field of external interfaces, and in particular to an external interface device and an access method for computer peripheral equipment. Background Art

[0002] The computer power interface is a computer peripheral device. The function of the power interface is to connect the computer host to an external power supply to provide power to the computer. This interface is usually designed to correspond to the output power jack of the power supply inside the computer host to ensure the normal operation of the computer. Computer peripheral devices usually refer to hardware devices that are connected to a computer or other host and do not need to be installed inside the host. These devices exchange data and supply power with the host through the interface, thereby enhancing the portability of the device. At the same time, these devices can be powered independently, reducing the energy consumption of the host and improving the stability and reliability of the system.

[0003] Some invention patents related to external connection are disclosed in the prior art. A Chinese patent with publication number CN212933465U discloses a computer power supply with an external charging interface. The computer power supply includes a power supply case and a power module arranged inside the computer case. The computer power supply is also provided with a switch module and multiple charging components. The switch module is electrically connected to the power module, wherein the charging components include a constant voltage module, a fast charging module and a charging interface. The constant voltage module, the fast charging module and the charging interface are connected in sequence, and the constant voltage modules of each charging component are respectively connected in parallel to the switch module.

[0004] In the prior art, the interface of the external power supply of the computer is mostly fixed, and mostly adopts a plug-in connection, which is fixed by the extrusion and friction between the plug and the inner wall of the socket to form a certain degree of stability. However, in actual application, this fixed plug, on the one hand, will cause the wiring terminal to protrude outward, and after docking, the connecting line needs to be bent and extended to another device for connection, which is easy to cause bending damage to the connection point between the connecting line and the plug wiring. On the other hand, it is easy to become loose under the pulling of external force, affecting the stability of the voltage of the external power supply. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an external interface device and access method for computer peripheral equipment.

[0006] In order to achieve the above purpose, the technical solution adopted by the present invention is:

[0007] In a first aspect, an external interface device for a computer peripheral device is provided, comprising a cover plate and a circuit board, and further comprising:

[0008] A connecting socket, the end of which is fixedly plugged with three electrical terminals;

[0009] A capacitor, one end of which is electrically connected to the circuit board, and the other end of which is electrically connected to two electrical terminals of the connector through a neutral wire and a live wire respectively;

[0010] A rotating seat, the rotating seat is rotatably connected to the two ear plates of the connecting seat, and is connected to an external socket through a connecting assembly, the external socket has a plug interface, three conductive plugs are fixedly plugged into the plug interface, the three conductive plugs are electrically connected to the three power terminals respectively through a conductive wire group, and a power plug is plugged into the plug interface;

[0011] Two clamping claws, the two clamping claws are symmetrically arranged inside the plug interface to clamp the power plug plugged into the plug interface;

[0012] The locking assembly is used to lock the state of the external socket and lock the two clamping claws when the external socket and the rotating seat are flipped to vertically upward or vertically downward to maintain the stability of the power connection.

[0013] It should be understood that the cover is fixedly mounted on the computer housing by bolts, the two sides of the circuit board are positioned on the inner wall of the computer housing by bolts, and the two ends of the capacitor are electrically connected to the circuit board and the two power terminals respectively. The capacitor is used to charge the capacitor when the power supply voltage is higher than the voltage across the load (capacitor) to keep the voltage across the load unchanged; when the power supply voltage is lower than the voltage across the load, the capacitor discharges to the load to keep the voltage across the load unchanged with the power supply voltage. This mechanism helps to smooth out voltage fluctuations, making the voltage stabilization effect better and the ripple smaller, thereby improving the performance and stability of the circuit.

[0014] When an external power source is needed, the power plug is inserted into the plug interface, electrically connected to the three conductive plugs, and then the external socket is turned over, and the external socket will synchronously drive the rotating seat to turn over. When the external socket and the rotating seat are turned to vertically upward or vertically downward, the locking component is locked, that is, the state of the rotating seat is locked, and the two clamping claws are locked to maintain the stability of power connection;

[0015] During the process of flipping the external socket after the power connection is completed, the external socket is flipped upward or downward to achieve the natural extension of the power connection direction downward or the extension of the power connection direction upward. In the process of flipping the external socket, when the plug connector is flipped to vertically upward or vertically downward along the rotating seat, the locking component locks the state of the rotating seat and locks the two clamping claws to maintain the stability of the power connection;

[0016] The locking of the rotating seat after flipping reduces the space at the rear end of the computer host occupied by the power plug, and provides an opportunity to adjust along the wiring direction required by the wire, which is conducive to reducing the degree of bending at the connection point of the power plug and the connecting wire, thereby helping to avoid bending damage to the connection point of the connecting wire and the plug wiring;

[0017] The clamping and locking of the power plug ensures that the power plug is firmly positioned in the socket of the external socket, which helps to prevent the connection between the power plug and the external socket from loosening due to external force, thereby maintaining the stability of the power supply and preventing unstable power supply caused by loose connection. This helps to further maintain the stability of the voltage during the external power supply process under the voltage stabilization effect of the capacitor.

[0018] As a further embodiment of the present invention, the connection assembly comprises:

[0019] A connecting groove is provided on the surface of the rotating seat, the external socket is inserted into the connecting groove, and a first supporting spring is fixedly connected between the external socket and the inner wall of the connecting groove.

[0020] It should be understood that when the power plug is plugged into the external socket, if the docking is not accurate, the external socket will compress the first support spring under the plugging force, and the first support spring will give way to a certain degree of elasticity to reduce the rigidity.

[0021] As a further embodiment of the present invention, it also includes:

[0022] Two limiting grooves, the two limiting grooves are respectively arranged on two side walls of the connecting groove;

[0023] Two limit blocks are symmetrically fixedly connected to two ends of the external socket and are slidably arranged in the two limit grooves respectively.

[0024] It should be understood that by providing the limiting groove and the limiting block, the sliding direction of the external socket and the connecting groove is restricted, thereby preventing the connecting socket from turning over in the connecting groove.

[0025] As a further embodiment of the present invention, the locking assembly comprises:

[0026] Two linkage plates, the two linkage plates are respectively fixedly connected to the surfaces of the two clamping claws and respectively penetrate the external sockets, and linkage grooves are respectively opened on the surfaces of the two linkage plates, and the linkage grooves include straight grooves and oblique grooves;

[0027] Two linkage pins, the two linkage pins are slidably arranged in the two straight grooves respectively, and the ends are fixedly connected with connecting plates, and the two connecting plates are respectively connected with sliding support members between the two sides of the external socket;

[0028] Two supporting pins, wherein elastic supporting members are connected between the two supporting pins and the two connecting plates respectively;

[0029] Two cam grooves, the two cam grooves are respectively fixedly connected to the two sides of the connecting seat, the cam grooves include a first arc groove and two clamping grooves, and the supporting pin is slidably arranged in the first arc groove.

[0030] It should be understood that in the process of flipping the external socket, the external socket will drive the linkage plate, the connecting plate and the supporting pin to move synchronously, the supporting pin will move in the first arc groove, the first arc groove will push the supporting pin outward, the supporting pin will push the elastic supporting member, the elastic supporting member will synchronously push the connecting plate, the connecting plate drives the linkage pin from the straight groove into the inclined groove, and in the process of the linkage pin moving in the inclined groove, the linkage pin will push the linkage plate, so that the linkage plate drives the clamping claw to clamp the power plug, after the clamping claw clamps the power plug, when the supporting pin continues to push the elastic supporting member, the elastic supporting member will be compressed, always giving the connecting plate a pushing tendency force, and gradually increasing the thrust until the supporting pin moves to the end of the first arc groove, and under the support of the elastic supporting member, the supporting pin moves into the clamping groove, at this time, the first pair of supporting pin positions are positioned, and the supporting pin is maintained with a stable pushing tendency force, thereby ensuring that the clamping claw stably clamps the power plug;

[0031] It should be noted that after the external socket is flipped and adjusted, the locking assembly not only realizes the positioning of the external socket in the flipped state, but also maintains the clamping force of the clamping claws to clamp the power plug, which is conducive to maintaining a stable connection between the power plug and the external socket.

[0032] As a further embodiment of the present invention, a groove is provided in the middle of the inner wall of the arc-shaped groove, and the groove is used to limit the support pin when the support pin is in the middle position of the first arc-shaped groove.

[0033] It should be understood that by providing the groove, when the support pin is located in the middle position of the first arc-shaped groove, the support pin will fall into the groove under the support of the elastic support member, and the position of the support pin is maintained under the limit of the groove, thereby indirectly maintaining the state of the rotating seat and the external socket, so that the external socket is oriented in a direction convenient for docking with the power plug, which is convenient for the user to have enough space and observation field to dock the power plug;

[0034] It should be further explained that when the external socket needs to be flipped over, the support pin will squeeze the elastic support member to give way and disengage from the groove.

[0035] In a second aspect, a method for accessing an external interface device of a computer peripheral device is provided, comprising the following steps:

[0036] Step 1: Connect the power plug: Insert the power plug into the socket of the external socket to make a conductive connection with the external power source;

[0037] Step 2, flipping the external socket: flipping the external socket upward or downward, so that the power connection direction is naturally extended downward or along the power connection direction of the upward direction, and in the process of flipping the external socket, when the locking component flips the external socket and the rotating seat to vertically upward or vertically downward, the state of the external socket is locked, and the two clamping claws are locked to maintain the stability of the power connection;

[0038] Step 3: Power on: Turn on the external power supply to power on.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] The present invention inserts a power plug into the plug interface and electrically connects with three conductive plugs, then flips the external socket, and the external socket will synchronously drive the rotating seat to flip. When the external socket and the rotating seat are flipped to vertically upward or vertically downward, the locking component is locked, that is, the state of the rotating seat is locked, and the two clamping claws are locked to maintain the stability of power connection.

[0041] The locking of the rotating seat in the flipped state reduces the space at the rear end of the computer host occupied by the power plug and provides an opportunity to adjust the wiring direction along the required wiring of the wire, which is beneficial to reduce the degree of bending at the wiring point of the power plug and the connecting wire, thereby helping to avoid bending damage to the wiring point of the connecting wire and the plug wiring.

[0042] The clamping and locking of the power plug ensures that the power plug is firmly positioned in the socket of the external socket, which is beneficial to prevent the connection between the power plug and the external socket from loosening due to external force, thereby maintaining the stability of power supply and avoiding unstable power supply caused by loose power connection. It is beneficial to further maintain the stability of voltage during external power-on under the voltage stabilizing effect of the capacitor. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0059] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0060] like Figures 2 to 15 The external interface device of a computer peripheral device shown in the figure comprises a cover plate 1 and a circuit board 2, and also comprises:

[0061] A connecting base 3, the end of which is fixedly plugged with three electrical terminals 4;

[0062] A capacitor 5, one end of the capacitor 5 is electrically connected to the circuit board 2, and the other end of the capacitor 5 is electrically connected to two power terminals 4 of the connector 3 through a neutral line 6 and a live line 7 respectively;

[0063] The rotating seat 9 is rotatably connected to the two ear plates of the connecting seat 3, and is connected to an external socket 10 through a connecting assembly. The external socket 10 has a plug interface 101, and three conductive plugs 102 are fixedly plugged into the plug interface 101. The three conductive plugs 102 are electrically connected to the three power terminals 4 through conductive wire groups 103 respectively, and a power plug 11 is plugged into the plug interface 101;

[0064] Two clamping jaws 12, the two clamping jaws 12 are symmetrically arranged inside the plug interface 101, and clamp the power plug 11 plugged into the plug interface 101;

[0065] The locking assembly is used to lock the state of the external socket 10 and lock the two clamping claws 12 when the external socket 10 and the rotating seat 9 are flipped to vertically upward or vertically downward to maintain the stability of the power connection.

[0066] Specifically, two of the three power terminals 4 are used for connecting the live wire 7 and the neutral wire 6 , and the other power terminal 4 is used for connecting the ground wire 8 , and one end of the ground wire 8 away from the power terminal 4 is connected to the cover plate 1 .

[0067] It should be understood that the cover plate 1 is fixedly mounted on the housing of the computer host by bolts, the two sides of the circuit board 2 are positioned on the inner wall of the housing of the computer host by bolts, and the two ends of the capacitor 5 are electrically connected to the circuit board 2 and the two power terminals 4 respectively. The capacitor 5 is used when the power supply voltage is higher than the voltage across the load capacitor 5, the power supply charges the capacitor 5 to keep the voltage across the load unchanged; when the power supply voltage is lower than the voltage across the load, the capacitor 5 discharges to the load to keep the voltage across the load unchanged with the power supply voltage. This mechanism helps to smooth out voltage fluctuations, making the voltage stabilization effect better and the ripple smaller, thereby improving the performance and stability of the circuit.

[0068] When an external power source is needed, the power plug 11 is inserted into the plug port 101, electrically connected to the three conductive plugs 102, and then the external socket 10 is turned over, and the external socket 10 will synchronously drive the rotating seat 9 to turn over. When the external socket 10 and the rotating seat 9 are turned over to vertically upward or vertically downward, the locking assembly is locked, that is, the state of the rotating seat 9 is locked, and the two clamping claws 12 are locked to maintain the stability of the power connection;

[0069] During the process of flipping the external socket 10 after the connection is completed, the external socket 10 is flipped upward or downward to achieve the natural extension of the connection direction downward or the connection direction upward. In the process of flipping the external socket 10, the locking component locks the state of the rotating seat 9 when the plug connector is flipped to vertically upward or vertically downward along with the rotating seat 9, and the two clamping claws 12 are locked to maintain the stability of the connection.

[0070] The locking of the rotating seat 9 after flipping reduces the space at the rear end of the computer host occupied by the power plug 11, and provides an opportunity to adjust along the wiring direction required by the wire, which is conducive to reducing the degree of bending at the connection point of the power plug 11 and the connecting wire, thereby helping to avoid bending damage to the connection point of the connecting wire and the plug wiring;

[0071] The clamping and locking of the power plug 11 realizes the stable positioning of the power plug 11 in the socket of the external socket 10, which is conducive to preventing the connection between the power plug 11 and the external socket 10 from loosening due to external force, thereby maintaining the stability of power supply and preventing the power supply from being unstable due to loose connection. It is conducive to further maintaining the stability of voltage during the external power supply process under the voltage stabilizing effect of the capacitor 5.

[0074] It should be understood that in the process of plugging the power plug 11 into the external socket 10, if the docking is not accurate, the external socket 10 will compress the first support spring 14 under the plugging force, and the first support spring 14 will give a certain elasticity to reduce the rigidity.

[0076] Two limiting grooves 15, the two limiting grooves 15 are respectively opened on two side walls of the connecting groove 13;

[0077] Two limit blocks 16 are symmetrically fixedly connected to two ends of the external socket 10 and are slidably disposed in the two limit slots 15 .

[0078] It should be understood that by providing the limiting groove 15 and the limiting block 16 , the sliding direction of the external socket 10 and the connecting groove 13 is limited, thereby preventing the connecting socket 10 from turning over in the connecting groove 13 .

[0079] As a further embodiment of the present invention, the locking assembly comprises:

[0080] Two linkage plates 17, the two linkage plates 17 are respectively fixedly connected to the surfaces of the two clamping claws 12, and respectively penetrate the external socket 10, and linkage grooves 18 are opened on the surfaces of the two linkage plates 17, and the linkage grooves 18 include a straight groove 1801 and an oblique groove 1802;

After the clamping jaw 12 clamps the power plug 11, when the support pin 21 continues to push the elastic support member, the elastic support member will be compressed, always giving the connecting plate 20 a pushing force, and gradually increasing the thrust until the support pin 21 moves to the end of the first arc-shaped groove 2201. Under the support of the elastic support member, the support pin 21 moves into the clamping groove 2202. At this time, the first pair of support pins 21 are positioned, and the support pins 21 are maintained to maintain a stable pushing force, thereby ensuring that the clamping jaw 12 stably clamps the power plug 11.

[0085] It should be noted that after the external socket 10 is flipped and adjusted, the locking assembly not only realizes the positioning of the external socket 10 in the flipped state, but also maintains the clamping force of the clamping claw 12 to clamp the power plug 11, which is conducive to maintaining a stable connection between the power plug 11 and the external socket 10.
