Charging equipment

Abstract

The present application provides a charging device, including a shell, two limit members, a charging member, and a transmission assembly. The shell has a receiving space and an abutment surface. Two limit members are arranged on the abutment surface, and the two limit members are axially symmetrically arranged and can rotate. The charging member is installed in the shell, and the charging member corresponds to the area between the two limit members. The transmission assembly is installed in the shell, and the transmission assembly connects the two limit members. When one of the limit members rotates along a first direction, it drives the transmission assembly to move. The movement of the transmission assembly can drive the other limit member to rotate synchronously in a direction opposite to the first direction, and the two limit members move in opposite directions. By adding a transmission assembly to the receiving space in the shell, as long as one limit member rotates outward, the transmission of the transmission assembly can make the other limit member rotate outward synchronously, so that the electronic device will not be offset during the movement. The position accuracy of the electronic device relative to the charging member is improved.

[0002] At present, electronic devices are usually placed on charging devices and charged by charging components on the charging devices. However, since the position of the charging components on the charging devices is fixed, if the electronic devices are not positioned accurately with the charging components when placed, the charging efficiency of the electronic devices will be reduced, or even charging will fail. Summary of the invention

[0004] A shell having a receiving space, wherein the shell has an abutting surface;

[0005] Two limiting members are arranged on the abutting surface, the two limiting members are arranged axially symmetrically, each limiting member can rotate around its own rotation center, and each limiting member is extended from the rotation center toward the direction close to the other limiting member;

[0006] A charging component, mounted on the housing, the charging component corresponds to the area between the two limiting components; and

[0007] A transmission assembly is mounted on the shell, and the transmission assembly is connected to the two limit members. When one of the limit members rotates along a first direction, it drives the transmission assembly to move. The movement of the transmission assembly can drive the other limit member to rotate synchronously in a direction opposite to the first direction, and the two limit members move in opposite directions.

[0008] The charging device provided by the present application firstly adds two limit members on the abutting surface of the shell, and uses the two limit members to limit the electronic device, so that the electronic device is limited between the two limit members.

When the electronic device abuts against the two limit members, as long as one of the limit members rotates outward, the other limit member can be synchronously rotated outward through the transmission of the transmission assembly, so that the electronic device will not be offset during the movement, and is always stuck in the middle of the two limit members, that is, the center line of the electronic device always coincides with the center line of the two limit members. The position accuracy of the electronic device relative to the charging component is improved, and the charging efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following are preferred implementations of the present application. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications are also considered to be within the scope of protection of the present application.

[0029] Before introducing the technical solution of the present application, the technical problems in the related technology are introduced in detail.

[0030] In daily life, charging devices are usually used to charge electronic devices. Specifically, the charging device includes a charging piece, which can be of various structures, for example, a wireless charging coil. At this time, you only need to place the electronic device on the charging device and align the receiving coil of the electronic device with the charging coil of the charging device to charge the electronic device. However, the electronic device usually cannot be aligned with the charging piece when placed, resulting in inaccurate positioning of the electronic device and the charging piece, reducing the charging efficiency of the electronic device. If the position difference between the electronic device and the charging piece is too large, charging may not even be possible.

[0031] In order to solve the above problems, this application provides a charging device. Please refer to Figure 1-Figure 6 , Figure 1 It is a schematic diagram of the three-dimensional structure of a charging device in one embodiment of the present application. Figure 2 This is a perspective view of a charging device in one embodiment of the present application. Figure 3 for Figure 1 Schematic diagram of the cross section along the AA direction. Figure 4 This is a schematic diagram of an electronic device not abutting against a limiting member in one embodiment of the present application. Figure 5 This is a schematic diagram of an electronic device abutting against a limiting member in one embodiment of the present application. Figure 6 It is a schematic diagram of an electronic device when the movement is completed in one embodiment of the present application. The embodiment of the present application provides a charging device 1, including a shell 10, two limit members 20, a charging member 30, and a transmission assembly 40. Among them, the shell 10 has a receiving space 11, and the shell 10 has an abutment surface 12. Two limit members 20 are arranged on the abutment surface 12, and the two limit members 20 can rotate in a direction parallel to the abutment surface 12. Each of the limit members 20 can rotate around its own rotation center 200. The two limit members 20 are axially symmetrical, and each of the limit members 20 extends from the rotation center 200 toward the direction close to the other limit member 20. The charging member 30 is installed in the shell 10, and the charging member 30 corresponds to the area between the two limit members 20. The transmission assembly 40 is mounted on the housing 10, and the transmission assembly 40 is connected to the two limiting members 20. When one of the limiting members 20 rotates in a first direction, the transmission assembly 40 is driven to move, and the movement of the transmission assembly 40 can drive the other limiting member 20 to rotate synchronously in a direction opposite to the first direction, and the two limiting members 20 move in opposite directions. It can also be understood that when the electronic device 2 abuts against the two limiting members 20, one of the limiting members 20 rotates in a direction away from the electronic device 2 and drives the transmission assembly 40 to move, and the movement of the transmission assembly 40 can drive the other limiting member 20 to rotate synchronously in a direction away from the electronic device 2.

[0032] The charging device 1 provided in this embodiment includes but is not limited to an adapter (i.e., a charger), which is used to charge mobile phones, smart watches, Bluetooth headsets, tablet computers, laptop computers, PDAs, and other electronic devices 2 with charging functions. The following text of this application uses the charging device 1 as an adapter and the electronic device 2 as a mobile phone for illustration. Optionally, the charging device 1 can be a wired charging device 1, that is, the charging device 1 and the electronic device 2 are charged by transmitting electrical energy through a charging line to charge the electronic device 2. Alternatively, the charging device 1 can also be a wireless charging device 1, that is, the charging device 1 and the electronic device 2 can be charged through a charging coil when they are close to each other.

[0033] The charging device 1 provided in this embodiment includes a housing 10, and a receiving space 11 is provided in the housing 10. The housing 10 is used to carry and protect various structural components arranged in the receiving space 11. In addition, part of the appearance surface of the housing 10 can also be used as an abutment surface 12, which is used to carry the electronic device 2, so that the electronic device 2 is placed on the housing 10 and then cooperates with the charging component 30 for charging.

[0034] In addition, the charging device 1 generally includes a horizontal charging device 1 and a vertical charging device 1. When the charging device 1 is a horizontal charging device 1, it generally includes a shell 10, and the abutting surface 12 is horizontal. When the charging device 1 is a vertical charging device 1, it generally includes at least two shells 10, and the shells 10 are arranged at an angle, so that the abutting surface 12 is an inclined surface, so that the electronic device 2 can be "standing up" when charging, and does not affect the viewing of the picture on the display screen of the electronic device 2. The charging device 1 provided in this embodiment is illustrated as a vertical charging device 1. Of course, in other embodiments, the charging device 1 can also be a horizontal charging device 1.

[0035] The charging device 1 provided in this embodiment also includes two limiting members 20. The function of the two limiting members 20 is to limit the position of the electronic device 2 in one direction on the abutting surface 12, so that the electronic device 2 cannot be placed randomly on the abutting surface 12, but must be placed between the two limiting members 20. When the electronic device 2 abuts against the two limiting members 20, since one limiting member 20 extends toward the other limiting member 20, the two limiting members 20 can rotate in a direction away from the electronic device 2, thereby increasing the distance between the two limiting members 20, which does not affect the continued movement of the electronic device 2 and can also play the role of limiting the electronic device 2.

[0036] The charging device 1 provided in this embodiment also includes a charging component 30, and the charging device 1 mainly charges the electronic device 2 through the charging component 30. The charging component 30 can be a wired charging component 30, and the charging component 30 can be arranged outside the housing 10 to cooperate with the socket of the electronic device 2 for charging. Alternatively, the charging component 30 can also be a wireless charging component 30, and the charging component 30 can be arranged in the housing 10, that is, in the receiving space 11. For example, the charging component 30 is a wireless charging coil to cooperate with the receiving coil in the electronic device 2 for charging. This embodiment is illustrated as a wireless charging coil.

[0037] Furthermore, the charging component 30 corresponds to the area between the two limiting members 20, that is, there are various positional relationships between the charging component 30 and the two limiting members 20. For example, the charging component 30 can be arranged between the two limiting members 20, or the charging component 30 can be arranged on one side of the two limiting members 20. However, no matter where the charging component 30 is arranged, the charging component 30 corresponds to the area between the two limiting members 20. In other words, in the direction parallel to the movement of the electronic device 2 (such as Figure 4As shown in the direction D3 in the figure, the orthographic projection of the charging component 30 on the two limiting members 20 is located between the two limiting members 20. Since the electronic device 2 is limited between the two limiting members 20, making the charging component 30 correspond to the area between the two limiting members 20 can improve the alignment accuracy between the electronic device 2 and the charging component 30 and improve the charging efficiency. Optionally, the charging component 30 is arranged on the midline of the two limiting members 20 (such as Figure 2 That is, the charging member 30 is arranged corresponding to the center between the two limiting members 20. In other words, the distance between the charging member 30 and the two limiting members 20 is equal.

[0038] The charging device 1 provided in this embodiment further includes a transmission assembly 40, which is disposed in the receiving space 11 and connects the two stoppers 20. The function of the transmission assembly 40 is to transmit force, and transmit the force of one stopper 20 to the other stopper 20 through the transmission and displacement of the transmission assembly 40, so that the other stopper 20 can also move synchronously. For example, when the electronic device 2 abuts against the two stoppers 20, one of the stoppers 20 flips outward (such as Figure 5 Then, the stopper 20 can rotate in the second direction (as shown in the D1 direction) through the movement of the transmission assembly 40. Figure 5 The direction D2 in the figure is transmitted to another stopper 20, so that the other stopper 20 also rotates outward (as shown in the direction D2 in the figure). Figure 5 The other direction D1 is shown in the figure), and finally the two limit members 20 are rotated outward synchronously. As a result, the electronic device 2 will not deviate during the movement and will always be stuck in the middle of the two limit members 20, that is, the center line of the electronic device 2 always coincides with the center line of the two limit members 20. The position accuracy of the electronic device 2 relative to the charging member 30 is improved, and the charging efficiency is improved. At this time, if the charging member 30 is also arranged on the center line of the two limit members 20, the electronic device 2 can be aligned with the charging member 30 in the arrangement direction of the two limit members 20.

[0039] Please refer to Figure 7 , Figure 7 Schematic diagram of the three-dimensional structure of the transmission assembly 40 and the limiting member 20 in one embodiment of the present application. In this embodiment, the transmission assembly 40 includes two rotating members 41 and two connected transmission members 42, one limiting member 20 is connected to one rotating member 41, and one transmission member 42 is rotatably connected to a first side 411 of one rotating member 41; another limiting member 20 is connected to another rotating member 41, and another transmission member 42 is rotatably connected to a second side 412 of another rotating member 41, wherein the first side 411 and the second side 412 are arranged opposite to each other;

[0040] When one of the limiting members 20 rotates in a direction away from the electronic device 2, it can drive one of the rotating members 41 to rotate in a first direction and drive the two transmission members 42 to move in a second direction. At the same time, it can drive the other rotating member 41 to rotate in a direction opposite to the first direction, so as to drive the other limiting member 20 to rotate synchronously in a direction away from the electronic device 2.

[0041] This embodiment provides a specific structure of a transmission assembly 40. The transmission assembly 40 may include a rotating member 41 and a transmission member 42. When a stopper 20 rotates outward, it can drive a rotating member 41 to rotate along a first direction. The first direction here can also be understood as the same rotation direction as the stopper 20 (e.g., Figure 7 The rotation of the rotating member 41 can drive the transmission member 42 connected to the transmission member 42 to move along the second direction (as shown in the direction D1 in FIG. 1 ). Figure 7 The second direction can be leftward or rightward. When the transmission member 42 moves, it can drive another transmission member 42 to move as well. At the same time, the movement of another transmission member 42 can drive another rotating member 41 in the opposite direction to the first direction (such as Figure 7 The other limiting member 20 is rotated in the direction D1 (as shown in the other direction D1), and finally drives the other limiting member 20 to rotate outward.

[0042] In addition, the present application does not limit which transmission member 42 is connected to the first side 411 of the rotating member 41, or which transmission member 42 is connected to the second side 412 of the rotating member 41. Figure 7 As shown, the transmission member 42 on the left can be connected to the lower side of the rotating member 41, and the rotation key on the right can be connected to the upper side of the rotating member 41, and the second direction is toward the left. Of course, in other embodiments, the transmission member 42 on the left can be connected to the upper side of the rotating member 41, and the rotation key on the right can be connected to the lower side of the rotating member 41, and the second direction is toward the right.

[0043] Optionally, the rotating member 41 includes but is not limited to a gear, and the transmission member 42 includes but is not limited to a rack.

[0044] Please refer to Figure 8 , Figure 8 In another embodiment of the present application Figure 1Partial cross-sectional schematic diagram along the AA direction. In this embodiment, the transmission assembly 40 further includes a support member 43 and an elastic member 44, and the two transmission members 42 are respectively connected to opposite sides of the support member 43; the housing 10 is provided with a blocking member 13, and the blocking member 13 is arranged in the receiving space 11, and the blocking member 13 and at least one of the transmission members 42 are arranged on the same side of the support member 43; one end of the elastic member 44 contacts the support member 43, and the other end of the elastic member 44 contacts the blocking member 13; when the two transmission members 42 move, the elastic member 44 is in a deformed state.

[0045] In this embodiment, the transmission assembly 40 may further include a support member 43 and an elastic member 44, wherein the support member 43 is used as an intermediate member to connect the two transmission members 42, that is, the two transmission members 42 are respectively connected to the opposite sides of the support member 43. And because one transmission member 42 is to be connected to the first side 411 of the rotating member 41, and the other transmission member 42 is to be connected to the second side 412 of the rotating member 41, the transmission member 42 on one side may be arranged at a lower position, and the transmission member 42 on the other side may be arranged at an upper side.

[0046] In addition, the housing 10 is further provided with a blocking member 13, and the number of the blocking member 13 may be one, that is, the blocking member 13 and one transmission member 42 may be provided on one side of the support member 43. Alternatively, the number of the blocking members 13 may be two, and the blocking members 13 may be provided on opposite sides of the support member 43, that is, the blocking member 13 and two transmission members 42 may be provided on the same side of the support member 43. Subsequently, an elastic member 44 may be added so that both ends of the elastic member 44 contact the support member 43 and the blocking member 13, so that when the transmission member 42 moves, the elastic member 44 will be elastically deformed, thereby generating a restoring force, and the restoring force may cause the transmission member 42 to move in the reverse direction, thereby causing the rotating member 41 and the limiting member 20 to move in the reverse direction (i.e., move in the direction close to the electronic device 2) and return to their original positions.

[0047] Alternatively, if Figure 8 As shown, when the elastic member 44 is arranged on the side close to the second direction, the elastic member 44 will be in a compressed state, and the elastic member 44 only needs to abut the support member 43 and the blocking member 13. Specifically, the support member 43 and the blocking member 13 are provided with a convex column, and the elastic member 44 is sleeved with the convex column. Alternatively, when the elastic member 44 is arranged on the side away from the second direction, the elastic member 44 will be in a stretched state, and the elastic member 44 only needs to connect the support member 43 and the blocking member 13. Specifically, the elastic member 44 bonds the support member 43 and the blocking member 13.

[0048] In this embodiment, by adding a support member 43, a blocking member 13, and an elastic member 44, when the electronic device 2 is completely charged and removed from the charging device 1, the restoring force of the elastic member 44 can cause the transmission member 42 to move in the opposite direction, thereby causing the rotating member 41 and the limiting member 20 to move in the opposite direction (i.e., in a direction close to the electronic device 2). Figure 4 In addition, when the electronic device 2 is inserted between the two stoppers 20, since the stoppers 20 will move toward the direction close to the electronic device 2, the two stoppers 20 will give the electronic device 2 a squeezing force, thereby clamping the electronic device 2 and improving the stability of the electronic device 2.

[0049] Please refer to Fig. 9 , Fig. 9 This is a perspective view of a charging device in another embodiment of the present application. In this embodiment, the housing 10 has a first side 14 and a second side 15 that are perpendicular to the second direction and are disposed opposite to each other, the second direction is toward the second side 15, and the transmission assembly 40 and the two stoppers 20 are disposed close to the first side 14.

[0050] In this embodiment, the transmission assembly 40 and the two stoppers 20 can be arranged close to the movement direction (i.e., the second direction) away from the transmission member 42. In other words, the transmission assembly 40 and the two stoppers 20 are arranged close to the first side 14. In this way, the distance between the transmission assembly 40 and the second side 15 can be increased, thereby reserving more space for the movement of the transmission assembly 40. It can also be understood that the angle at which the stoppers 20 can rotate is increased, and a larger electronic device 2 can be clamped.

[0051] Please refer to Figure 10-11 , Fig.10 It is a schematic diagram of the three-dimensional structure of the shell in one embodiment of the present application. Fig.11 It is a side view of a limit member, a transmission assembly, and a connector in one embodiment of the present application. In this embodiment, the charging device 1 also includes a connector 50, and the housing 10 has a through hole 16 connected to the accommodating space 11, and at least part of the connector 50 is arranged in the through hole 16, and one end of the connector 50 is connected to the limit member 20, and the other end is connected to the rotating member 41. In this embodiment, the connector 50 can be used to connect the limit member 20 and the rotating member 41 together. The connector 50 and the limit member 20 can be an integrated structure, and different names are artificially given to different parts for ease of understanding. Or the connector 50 and the limit member 20 can be a split structure.

[0052] Please refer to Figure 12-13 , Fig.12 This is a perspective view of a charging device in another embodiment of the present application. Fig.13The figure is a side view of a position-limiting member, a transmission assembly, and a connecting member in another embodiment of the present application. In this embodiment, the housing 10 has a first side 14 and a second side 15 which are perpendicular to the second direction and are arranged opposite to each other, and the second direction is toward the second side 15; the connecting member 50 includes a first portion 51, a second portion 52, and a third portion 53, the first portion 51 is connected to the position-limiting member 20, the third portion 53 is connected to the rotating member 41, the second portion 52 is bent and connected between the first portion 51 and the third portion 53, and the third portion 53 is closer to the first side 14 than the first portion 51.

[0053] In this embodiment, the connecting member 50 can be designed in a "Z" shape, so that the limiting member 20 and the rotating member 41 are not in the same direction, and the rotating member 41 is eccentrically arranged with respect to the rotating member 41, and is arranged close to the first side 14. In this way, the distance between the transmission component 40 and the second side 15 can be increased, thereby reserving more space for the movement of the transmission component 40, which can also be understood as increasing the rotation angle of the limiting member 20, and a larger electronic device 2 can be clamped.

[0054] Please refer to Fig.14 , Fig.14 Schematic diagram of the three-dimensional structure of the housing in another embodiment of the present application. In this embodiment, the housing 10 has a through hole 16 connected to the receiving space 11, and the through hole 16 extends in a direction away from the transmission member 42.

[0055] In this embodiment, a through hole 16 can be opened on the shell 10, and the opening of the through hole 16 can be extended in a direction away from the transmission member 42, so that the limit member 20 and the rotating member 41 can move along the extension direction of the through hole 16, thereby separating the rotating member 41 from the transmission member 42, and then the inclination angle of the limit member 20 can be adjusted to adjust the distance between the two limit members 20, so that the charging device 1 can adapt to electronic devices 2 of more sizes.

[0056] Optionally, when the transmission member 42 is connected to the upper side of the rotating member 41, the extension direction of the through hole 16 extends downward, and an adjustable baffle can be provided on the hole wall. When the angle does not need to be adjusted, the baffle is used to block the movement of the limiting member 20 in the through hole 16. When the angle needs to be adjusted, the baffle is withdrawn so that the limiting member 20 can move in the through hole 16.

[0057] Please refer to Fig.15 , Fig.15 In another embodiment of the present application Figure 1Partial cross-sectional schematic diagram of the housing along the AA direction. In this embodiment, the transmission assembly 40 further includes a support member 43, and the two transmission members 42 are respectively connected to opposite sides of the support member 43; the housing 10 is provided with a sliding structure 60, the sliding structure 60 is arranged in the receiving space 11, the sliding structure 60 is provided with a sliding groove 61, and the support member 43 is arranged in the sliding groove 61.

[0058] In this embodiment, a sliding structure 60 can be provided on the housing 10 in the receiving space 11, and a sliding groove 61 can be provided on the sliding structure 60, and the support member 43 is provided in the sliding groove 61. In this way, the support member 43 can slide in the sliding groove 61, thereby driving the movement of the two transmission members 42. Optionally, a baffle is also provided on the surface where the sliding groove 61 is provided to prevent the support member 43 from falling from the sliding groove 61.

[0059] Please refer to Fig.16 , Fig.16 This is a schematic diagram of the three-dimensional structure of a charging device in another embodiment of the present application. In this embodiment, the two limiting members 20 include a first limiting member 21 and a second limiting member 22, the first limiting member 21 includes a first sub-limiting member 211 and a second sub-limiting member 212, the second limiting member 22 includes a third sub-limiting member 221 and a fourth sub-limiting member 222, the first sub-limiting member 211 and the third sub-limiting member 221 are arranged axially symmetrically, the second sub-limiting member 212 and the fourth sub-limiting member 222 are arranged axially symmetrically, and the distance between the first sub-limiting member 211 and the third sub-limiting member 221 is greater than the distance between the second sub-limiting member 212 and the fourth sub-limiting member 222.

[0060] In this embodiment, the two limit members 20 may be the first limit member 21 and the second limit member 22, respectively, and each limit member 20 may be composed of two sub-limit members. And the sub-limit members are arranged in axial symmetry. The first sub-limit member 211 and the third sub-limit member 221, and the second sub-limit member 212 and the fourth sub-limit member 222 may be arranged along the moving direction of the electronic device 2. In addition, the distance between each group of limit members 20 may be set to be unequal, that is, the distance between the first sub-limit member 211 and the third sub-limit member 221 is greater than the distance between the second sub-limit member 212 and the fourth sub-limit member 222, so that more sizes of electronic devices 2 can be adapted. When a smaller electronic device 2 is inserted, there are sub-limit members with smaller spacing for it to use.

[0061] Please refer again Figure 1In this embodiment, the housing 10 is provided with a resisting member 70, which is provided outside the receiving space 11 and on one side of the extending direction of the limiting member 20. By adding the resisting member 70 to resist the electronic device 2, the position of the electronic device 2 in the moving direction is limited, thereby further improving the positioning accuracy between the electronic device 2 and the charging member 30 and further improving the charging efficiency.
