[0026] Please refer to Figure 1 to Figure 2 The utility model proposes a charging device, including multiple mobile terminals 13 and a charger 100, the charger 100 includes a host 11 and multiple charging seats 12, the host 11 is recessed with multiple installation cavities 112 arranged at intervals, the cavity wall of each installation cavity 112 is provided with a first electrode 111, the outer surface of each charging seat 12 is installed with a second electrode 121, each charging seat 12 at least partially enters any installation cavity 112, and each first electrode 111 is connected to each second electrode 121 in a one-to-one correspondence.

[0027] In this embodiment, the charger 100 can be a plug-in direct charging type. The multiple installation cavities 112 opened by the charging seat 12 correspond one-to-one to the multiple charging seats 12. For the scenario where only a single charging seat 12 is required, the required charging seat 12 can be installed. If there are a large number of mobile terminals 13 to be charged at the same time, the installation cavities 112 on the host 11 can be set to only meet the basic needs. There is no need to set the maximum number of mobile terminals 13. Therefore, the overall volume of the charger 100 can be effectively reduced.

[0028] In order to realize the detachable connection between the charging seat 12 and the host 11, a charging seat 12 is plugged into a mounting cavity 112, and the second electrode 121 provided on each charging seat 12 can be provided at the bottom or the peripheral side. The number of charging seats 12 can be greater than the number of charging cavities 123 on the host 11. Then, according to specific usage requirements, the required charging seats 12 are installed on the host 11. The parts of each charging seat 12 plugged into the mounting cavity 112 can be set to the same shape and size. In the process of plugging the charging seat 12, a charging seat 12 can be quickly plugged into any mounting cavity 112 without being placed in a special corresponding mounting cavity 112.

[0029] The bottom of the charging seat 12 enters the installation cavity 112, and the top surface of the charging seat 12 can be kept flush with the upward opening periphery of the installation cavity 112 of the host 11, so that the surfaces of multiple charging seats 12 are on the same plane, so that the surface of the charger 100 remains flat, which is convenient for users to take and use, and improves the aesthetics of the charger 100. Multiple charging seats 12 are plugged into the installation cavity 112, and the upwardly opening installation cavity 112 can also be effectively blocked, thereby preventing foreign matter from entering the installation cavity 112, resulting in a short circuit or poor contact between the first electrode 111 and the second electrode 121.

[0030] In this embodiment, each charging cavity 123 is provided with a charging electrode 124 , and the outer surface of each mobile terminal 13 is provided with a charging contact 131 . Each mobile terminal 13 is plugged into a charging cavity 123 , and each charging electrode 124 is connected to each charging contact 131 in a one-to-one correspondence.

[0031] Different mobile terminals 13 have different functions and forms. Multiple mobile terminals 13 are divided into multiple categories. The same category includes at least one mobile terminal 13 and the shape and size remain the same. The charging contacts 131 on the mobile terminals 13 of different categories are set at different positions on the outer surface. For different categories of mobile terminals 13, the charging electrodes 124 in the charging cavities 123 of multiple charging seats 12 are also set at different positions. At the same time, the shapes of each charging cavity 123 are different, and the charging cavities 123 of multiple charging seats 12 are set into different shapes corresponding to different categories of mobile terminals 13. With such a setting, different categories of mobile terminals 13 cannot enter the charging cavity 123 that does not match them, which can meet the charging needs of specific categories of mobile terminals 13. The easily replaceable charging seat 12 does not require additional expansion of the host 11 for specific categories of mobile terminals 13. While maintaining the overall small size of the charger 100, it also speeds up the charging efficiency of the mobile terminal 13.

[0032] Furthermore, each charging cavity 123 is provided with a convex positioning column 126 at the bottom of the cavity, and each mobile terminal 13 is provided with a concave positioning hole, and each positioning column 126 is plugged into each positioning hole one by one. The plug-in form of the positioning column 126 and the positioning hole allows the mobile terminal 13 to be installed in the charging cavity 123 and remain stable, avoiding the displacement of the mobile terminal 13 during the process of moving the charger 100, which affects the electrical connection between the charging electrode 124 and the charging contact. At the same time, the positioning holes can be provided with different shapes on both sides, and the corresponding positioning holes are also provided with different shapes on both sides, so that the plug-in of the positioning column 126 and the positioning hole has a fool-proof effect, ensuring that the charging contact provided on one side of the mobile terminal 13 corresponds to the direction of the charging electrode 124 in the charging cavity 123, thereby improving the plug-in assembly efficiency of the two.

[0033] In this embodiment, please refer to Figure 3 and Figure 4 , a connection column 122 is convexly provided at the bottom of each charging seat 12, and each installation cavity 112 is concavely provided with a plurality of connection holes 113 corresponding to each connection column 122, and each connection column 122 is plugged and matched with each connection hole 113 one by one. The connection columns 122 on the charging seat 12 can be arranged at each vertex of the bottom of the charging seat 12, so as to improve the connection stability between the charging seat 12 and the host 11. In other embodiments, the detachable connection between the charging seat 12 and the host 11 can be in the form of a latch, a buckle, etc., which is not limited here.

[0034] Furthermore, abutment portions 114 are convexly provided on the peripheral wall of each installation cavity 112, and a plurality of connection holes 113 are provided on each abutment portion 114. Each charging stand 12 is provided with a convex portion 125 extending along the peripheral edge, and a plurality of connection posts 122 are installed on each convex portion 125. When each connection post 122 is plugged into each connection hole 113 in a one-to-one correspondence, a convex portion 125 abuts against an abutment portion 114. The convex abutment portion 114 provided in the installation cavity 112 can effectively increase the length of the connection hole 113, and the length of the corresponding connection post 122 can also be increased. The longer connection post 122 and the connection hole 113 enhance the assembly connection strength between the charging stand 12 and the host 11. The abutment portion 114 and the protrusion 125 of the charging seat 12 abut against each other, which can effectively prevent over-fitting between the charging seat 12 and the mounting cavity 112. The abutment portion 114 and the protrusion 125 can limit the contact distance between the first electrode 111 and the second electrode 121, and can also achieve precise positioning of the first electrode 111 and the second electrode 121 according to the relative positions of the first electrode 111 and the second electrode 121.

[0035] A plurality of reinforcing ribs are provided between the outer surface of the recessed charging cavity 123 of the charging seat 12 and the plurality of connecting columns 122 provided on the protrusion 125 . The reinforcing ribs are used to enhance the structural strength of the protrusion 125 . During the installation process, the provided reinforcing ribs can effectively resist the pressure applied from the outside.

[0036] Specifically, each connection column 122 is provided with a through hole 1221. When a charging base 12 is assembled with the host 11, each through hole 1221 is connected to a connection hole 113. A screw assembly assembled in the corresponding through hole 1221 and the connection hole 113 is provided between the host 11 and each charging base 12. In other embodiments, a bolt or other assembly for connecting the through hole 1221 and the connection hole 113 may be provided between the through hole 1221 and the connection hole 113.

[0037] In this embodiment, a control board is provided in the host 11, and the control board is electrically connected to each first electrode 111. The control board is used to control the on / off state of each first electrode 111. The first electrode 111 in the on state is connected to the second electrode 121, and the first electrode 111 in the off state is not connected to the second electrode 121. The control board can control the on / off state of the first electrode 111 in the form of active control or passive control. The active control can be through an external button. After the charging stand 12 is installed on the host 11, the user controls the on / off state of the first electrode 111 by pressing a button, thereby realizing precise control of the on / off state of any first electrode 111. The passive control can be set to a contact sensing form. When the first electrode 111 contacts the second electrode 121, the sensor or other sensing form provided in the first electrode 111 is triggered, and the first electrode 111 is automatically controlled to be powered on, thereby realizing automatic and accurate sensing.

[0038] Specifically, each first electrode 111 includes an elastic portion 1111, each second electrode 121 is a planar electrode, each charging seat 12 is inserted into a mounting cavity 112, and a planar electrode abuts against an elastic portion 1111. The elastic portion 1111 extends outward to contact the planar electrode, and the elastic portion 1111 is compressed by the pressure of the planar electrode, so that the elastic portion 1111 accumulates elastic potential energy, and the elastic potential energy continuously applies pressure to the planar electrode, so that the elastic portion 1111 and the planar electrode remain in contact, thereby improving the electrical connection stability of the first electrode 111 and the second electrode 121. At the same time, the first electrode 111 can be provided with a pressure sensor that can detect the elastic potential energy, and when the elastic portion 1111 is compressed, the effect of automatically controlling the power supply of the first electrode 111 is achieved.

[0039] Furthermore, the charging contacts 131 provided on the mobile terminal 13 may also be provided as planar electrodes, and the charging electrode 124 exposed in the charging cavity 123 may also be provided with an elastic portion 1111. The contact relationship and contact method between the two are consistent with the above-mentioned first electrode 111 and second electrode 121, and will not be elaborated here.

[0040] In one embodiment, the first electrode 111 is provided with two elastic parts 1111 corresponding to the positive and negative electrodes respectively, and the planar electrode of the second electrode 121 is provided with positive and negative electrodes corresponding to the two elastic parts 1111. When the charging stand 12 provided with the second electrode 121 is installed on the host 11 in the correct direction, the positive and negative electrodes of the two elastic parts 1111 are connected to the positive and negative electrodes of the second electrode 121 in a corresponding manner. If the plug-in direction of the charging stand 12 is wrong, the positive and negative electrodes of the two elastic parts 1111 are not connected to the positive and negative electrodes of the second electrode 121 in a corresponding manner. The corresponding electrical connection relationship between the second electrode 121 and the first electrode 111 is set so that the installation direction of each charging stand 12 remains consistent, so that the user does not need to change the direction when charging. In other embodiments, for mobile terminals 13 with larger specifications, it is necessary to install them in the wrong direction for charging, which can also be achieved by adjusting the corresponding relationship between the positive and negative electrodes of the second electrode 121 and the first electrode 111.

[0041] In another embodiment, the control panel further includes a plurality of light-emitting components, which are exposed on the top surface of the host 11, and each light-emitting component is electrically connected to each first electrode 111 in a one-to-one correspondence, and the power-on and power-off states of the two are the same. The power-on state of the first electrode 111 is determined in the form of a light-emitting component. When the first electrode 111 is powered on, the light-emitting component is lit, and when the first electrode 111 is powered off, the light-emitting component is extinguished. The light-emitting component can also be associated with the state of connection between the first electrode 111 and the second electrode 121, and is electrically connected to the sensor in the above-mentioned first electrode 111. When the first electrode 111 is connected to the second electrode 121, the light-emitting component is turned on, and when the first electrode 111 is not connected to the second electrode 121, the light-emitting component is turned off.

[0042] In this embodiment, a mounting bracket 127 is protruded from one side of the charging stand 12 facing the host 11. The mounting bracket 127 extends into the mounting cavity 112 and a PCB is mounted on one end. The PCB is provided with a second electrode 121, and the bottom of the mounting cavity 112 is provided with a first electrode 111. The PCB and the mounting bracket 127 may be in a detachable connection form. The PCB is used to realize the electrical connection between the charging electrode 124 and the second electrode 121. In this way, the current transmitted by the first electrode 111 can be connected to the charging contact 131 through the second electrode 121 and the charging electrode 124. Similarly, a light-emitting element electrically connected to the charging electrode 124 may also be provided on the PCB. The light-emitting element may be used to prompt the user whether the charging electrode 124 and the charging contact 131 are connected after the mobile terminal 13 enters the charging cavity 123. When the two are connected, the light-emitting element is turned on, and when the two are disconnected, the light-emitting element is turned off.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
