Description

[Technical field]

[0001] The utility model relates to the technical field of charging equipment, in particular to a charging base and a charging device. [Background technology]

[0002] With the development of science and technology, the functions of smart electronic devices are becoming more and more abundant, and people are using smart electronic devices more and more frequently. Correspondingly, in daily life, the charging frequency of smart electronic devices is also increased. For the charging process of electronic devices, the traditional method is to charge by connecting with a data cable. Generally, it is necessary to align the interface of the data cable with the charging interface of the electronic device. During the connection process, it is usually necessary to hold the mobile phone with the hand to better connect the interface of the data cable with the charging interface of the electronic device. In order to improve the convenience of charging, some charging bases that automatically align with the charging interface have also appeared. That is, people put the charging interface of the electronic device roughly on the charging base when using it, and the charging port on the base can automatically align with the charging interface due to the magnetic attraction. However, after long-term use, the friction between the charging port and the base shell during each alignment operation will cause wear of the charging port, thereby reducing the service life.

[0049] Please refer to Figure 1-Figure 3 Combined with Figure 7 The first embodiment of the utility model provides a charging base 1 for charging an electronic device 2. The charging base 1 includes a shell 10 and a charging assembly 11. The shell 10 defines a receiving cavity 100 and a side of the shell 10 is provided with an avoidance hole 101 connected to the receiving cavity 100. A soft plastic part 14 is installed in the receiving cavity 100, and part of the soft plastic part 14 is exposed through the avoidance hole 101; the charging assembly 11 includes a circuit board 110 arranged in the receiving cavity 100 and a first charging head 111 that can pass through the soft plastic part 14 and be exposed to the shell 10. The first charging head 111 is electrically connected to the circuit board 110. The first charging head 111 and at least part of the soft plastic part 14 can be relative to the shell 10. Activity; Compared with the traditional automatic alignment charging device, the charging base 1 of the utility model is also provided with a soft rubber part 14 around the charging component 11. The soft rubber part 14 itself has the characteristics of good cushioning and easy deformation. When the electronic device 2 needs to be charged, the charging component 11 automatically aligns with the charging port of the electronic device 2, and the soft rubber part 14 also moves accordingly to ensure that the charging component 11 will not have friction contact with the shell 10 during the movement, thereby avoiding the friction loss of the charging component 11 caused by long-term movement and increasing the service life. At the same time, due to its good ductility, the soft rubber part 14 can also expand the range of movement of the charging component 11, thereby increasing the user's fault tolerance when performing blind alignment for charging.

[0050] Specifically, the soft plastic part 14 should also have a certain heat resistance because the charging component 11 will continue to emit heat during charging.

[0051] For further information, please refer to Figure 4-5BThe soft rubber part 14 includes a fixed part 140 connected to the shell 10, a movable part 141 surrounding the avoidance hole 101 and exposed from the shell 10, and a bent part 142 connecting the fixed part 140 and the movable part 141; the movable part 141 includes a fixed groove 143 arranged around the first charging head 111, and the movable part 141 can move relative to the shell 10; the bent part 142 limits the movable range of the charging component 11. Due to the deformable characteristics of the soft rubber, the charging component 11 can move freely within a certain range of the avoidance hole 101. At the same time, the bent part 142 also separates the charging component 11 from the edge of the avoidance hole 101, so that it will not contact the avoidance hole 101 during movement, reducing wear and tear during use.

[0052] Specifically, the extending direction of the bent portion 142 is toward the interior of the accommodating cavity 100 , and the overall shape is more beautiful, and the electrical connection between the charging assembly 11 and the electronic device 2 is not hindered.

[0053] Furthermore, the fixing portion 140 is provided with a plurality of mounting holes 1400, and a plurality of mounting posts 105 are correspondingly provided in the accommodating cavity 100. The mounting posts 105 pass through the mounting holes 1400 to fix the soft plastic part 14. The soft plastic part 14 is fixed from the inside of the base, making full use of the accommodating cavity 100 and reducing the thickness and volume of the device.

[0054] For further information, please refer to Figure 2 The movable portion 141 is provided with an inclined surface 1410 which is inclined from the fixed groove 143 toward the curved portion 142; the purpose of providing the inclined surface 1410 is to guide the movement direction of the charging component 11 during its movement; specifically, because the inclined surface 1410 has an inclined angle, the force direction of the fixed groove 143 is toward the curved portion 142, so that when the charging component 11 is charged, the charging component 11 arranged in the fixed groove 143 can move more easily toward the direction of the curved portion 142 under force, because the curved portion 142 is arranged around the fixed groove 143, that is, the charging component 11 can move around the avoidance hole 101.

[0055] Specifically, the setting of the inclined surface 1410 also physically separates the charging component 11 disposed in the fixing groove 143 from the avoidance hole 101, thereby reducing the wear of the charging component 11 and the avoidance hole 101 and increasing the service life.

[0056] Furthermore, please combine Figure 2 and Figure 3 The size of the avoidance hole 101 is larger than the size of the first charging head 111 and / or the depth of the accommodating cavity 100 is larger than the height of the charging component 11, so that the first charging head 111 drives the circuit board 110 to move horizontally and / or vertically relative to the shell 10; the size relationship of each component is limited, and the free movement of the charging component 11 can be guaranteed while reducing the contact wear between the components.

[0057] For further information, please refer to Figure 5A and Figure 5B The shell 10 is provided with a chamfered surface 107 around the edge of the avoidance hole 101 , thereby reducing the friction between the soft rubber part 14 and the avoidance hole 101 .

[0059] Specifically, the connecting member 1110 provided in the first embodiment of the present invention is a spring-type probe.

[0060] For details, please combine Figure 4-5B A through hole 144 is also provided in the fixing groove 143 , and the circuit board 110 is inserted into the accommodating cavity 100 through the through hole 144 , and the first charging head 111 is placed in the fixing groove 143 .

[0061] Furthermore, the height of the magnetic seat body 1113 is greater than the height of the magnetic element 1112; the raised portion of the magnetic seat body 1113 forms a guide section. When charging, the guide section is first connected to the charging port under the action of magnetic attraction, and then the connector 1110 is electrically connected to the charging port within the range of the guide section. Under the action of the secondary alignment, the connection success rate of the charging port can be greatly improved, ensuring the stability of the contacts after alignment.

[0062] Furthermore, the horizontal plane where the maximum height of the magnetic seat body 1113 is located is lower than the horizontal plane where the avoidance hole 101 is located; this design is to prevent the charging component 11 from moving out of the range of the avoidance hole 101 when connecting the electronic device 2, thereby improving the charging stability.

[0063] Furthermore, a counterweight 13 is provided in the accommodating cavity 100, and a plurality of support columns 106 are provided on two opposite sides of the shell 10 in the accommodating cavity 100, and the support columns 106 jointly abut against the counterweight 13; the provision of the counterweight 13 can improve the stability of the entire device when charging the electronic device 2, and the provision of the support columns 106 in the accommodating cavity 100 can limit the various parts in the accommodating cavity 100, and can also improve the equipment stability of the charging base 1.

A soft rubber part is installed in the receiving cavity, and part of the soft rubber part is exposed through the avoidance hole. The charging assembly includes a circuit board arranged in the receiving cavity and a first charging head that can pass through the soft rubber part and be exposed to the shell. The first charging head is electrically connected to the circuit board, and the first charging head and at least part of the soft rubber part can move relative to the shell. Compared with the traditional automatic alignment charging device, the charging base of the utility model is further provided with a soft rubber part around the charging assembly. The soft rubber part itself has the characteristics of good buffering and easy deformation. When the electronic device needs to be charged, the charging assembly automatically aligns with the charging port of the electronic device, and the soft rubber part also moves accordingly, ensuring that the charging assembly will not rub against the shell during the movement, avoiding the friction loss of the charging assembly due to long-term movement, and increasing the service life. At the same time, due to its good ductility, the soft rubber part can also expand the range of movement of the charging assembly, increasing the user's fault tolerance when blindly aligning the charging.

[0082] 2. The soft rubber part of the charging base provided by the utility model includes a fixed part connected to the shell, a movable part surrounding the avoidance hole and exposed from the shell, and a bent part connecting the fixed part and the movable part; the movable part includes a fixed groove arranged around the first charging head, and the movable part can move relative to the shell; the bent part limits the movable range of the charging component. Due to the deformable characteristics of the soft rubber, the charging component can move freely within a certain range of the avoidance hole. At the same time, the bent part also separates the charging component from the edge of the avoidance hole, so that it will not contact the avoidance hole during movement, thereby reducing wear and tear during use.

[0083] 3. The movable part of the charging base provided by the utility model is provided with an inclined surface inclined from the fixed groove to the curved part; the purpose of setting the inclined surface is to guide the movement direction of the charging component during movement; the edge of the shell surrounding the avoidance hole is provided with a chamfered inclined surface; the friction between the soft rubber part and the avoidance hole is reduced.

[0084] 4. The avoidance hole size of the charging base provided by the utility model is larger than the size of the first charging head and / or the depth of the accommodating cavity is larger than the height of the charging assembly, so that the first charging head drives the circuit board to move horizontally and / or vertically relative to the shell; the size relationship of each component is limited, and the free movement of the charging assembly can be guaranteed while reducing the contact wear between the components.

[0085] 5. The first charging head of the charging base provided by the utility model includes a connecting piece, which is a wire or a conductive spring or a spring-type probe; a fixing seat for fixing the connecting piece, a magnetic suction piece arranged around the fixing seat, and a magnetic suction seat body arranged around the magnetic suction piece, and the magnetic suction seat body is arranged in a fixing groove; the charging component is a hierarchical structure surrounded by layers, which improves the safety during charging, and the magnetic suction piece can drive the connecting piece to automatically align with the charging port of the electronic device when subjected to magnetic force; the height of the magnetic suction seat body is greater than the height of the magnetic suction piece; the raised part of the magnetic suction seat body forms a guide section, and when charging, the guide section is first connected to the charging port under the action of magnetic attraction, and then the connecting piece is electrically connected to the charging port within the range of the guide section, and under the action of secondary alignment, the connection success rate of the charging port can be greatly improved, and the stability of the contacts after alignment is guaranteed.

[0086] 6. The horizontal plane of the charging base provided by the utility model is lower than the horizontal plane where the avoidance hole is located; this design is to prevent the charging component from moving out of the range of the avoidance hole when connecting the electronic device, thereby improving the charging stability.

[0087] 7. The shell of the charging base provided by the utility model is provided with a plug-in slot on one side of the avoidance hole, and the charging base also includes a backrest, which is detachably arranged in the plug-in slot; the backrest is used to support the electronic device being charged, and due to the support of the backrest, the electronic device can maintain a more stable state when charging on the charging base; at the same time, the backrest is detachable and replaceable, which is convenient for replacing backrests of different sizes when charging different electronic devices, greatly facilitating the daily use of users; the interior of the backrest is provided with a support plate that at least abuts against the opposite sides of the backrest; the interior of the backrest is hollow, and the shape of the backrest supported by the support plate is not deformed, which reduces the weight of the charging base while conveniently supporting the electronic device, meeting the lightweight requirement.

[0088] 8. There is a gap between the end of the backrest of the charging base provided by the utility model that is close to the avoidance hole and the edge of the avoidance hole; the gap is set so that the electronic device can lean against the backrest when charging, so that the backrest can provide stable support for the electronic device and improve the charging stability of the charging device.

[0089] 9. The backrest of the charging base provided by the utility model is provided with a limit groove on one side close to the avoidance hole; the limit groove is a groove that is concave inward as a whole, and its purpose is to limit the movement of the electronic device leaning on the backrest, to ensure that the electronic device will not move easily due to external collision during charging, and to ensure the stability of charging.

[0090] 10. The utility model also provides a charging device, including a second charging head and the charging base as described above, one end of the second charging head is magnetically connected to the first charging head, and the other end is electrically connected to the electronic device; it has the same beneficial effects as the above-mentioned charging base, which will not be repeated here.

[0091] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the principles of the present invention should be included in the protection scope of the present invention.
