[0035] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] The following is a reference appendix. Figures 1 to 8 This invention describes a charging device according to an embodiment of the present invention.

[0037] like Figures 1 to 6 As shown, the charging device of this utility model embodiment includes: a battery cell 3, a housing 1, and a connector 2. The battery cell 3 is disposed inside the housing 1, and the housing 1 is provided with a storage area 13, the storage area 13 including a first direction (e.g., along a first direction). Figure 7 The first and second accommodating areas (131 and 132) are connected sequentially in the vertical direction.

[0038] The connector 2 includes a charging head 21, which is electrically connected to the battery cell 3. The charging head 21 includes a connected charging base 211 and a plug 212. In the stored state, the plug 212 is inserted into the first receiving area 131, and the charging base 211 is fixed to the second receiving area 132. In the first use state, the charging base 211 is fixed to the second receiving area 132, and the plug 212 and the first receiving area 131 are located on both sides of the charging base 211.

[0039] According to the charging device of the embodiment of the utility model, when the user does not use the charging device, it can be switched to the storage state, at this time, the plug part 212 is inserted into the first containing area 131 to store the plug part 212, which reduces the risk of damage of the plug part 212 due to collision of external articles. When the user uses the charging device, it can be switched to the first use state, at this time, the plug part 212 and the first containing area 131 are located on both sides of the charging seat 211 along the first direction to move the plug part 212 out of the first containing area 131, thereby facilitating the user to charge through the plug part 212. And the charging device can fix the charging seat 211 in the second containing area 132 in the first use state, which can avoid the problem of poor contact of the plug part 212 with the mobile terminal due to the shaking of the charging head 21, and is beneficial to improve the user experience.

[0040] It can be understood that the charging device of the embodiment of the utility model can be relatively fixed with the second containing area 132 whether in the storage state or in the first use state, thereby avoiding the problem of shaking of the charging head 21 relative to the shell 1 when the charging device is in the storage state or the first use state, and improving the firmness of the connection of the charging head 21.

[0041] Among them, the structure of the plug part 212 can be type-c type, micro type or lightning type, so as to different interface type electronic equipment, the utility model does not make limitation to the specific type of plug part 212.

[0042] The charging device of the embodiment of the utility model can be a mobile power supply and can be miniaturized to facilitate the user to carry.

[0043] Optionally, the wall surface of the shell 1 is provided with an open mouth 113, the open mouth 113 constitutes at least part of the second containing area 132, and the first containing area 131 is located in the shell 1. In the first use state, the plug part 212 is located on the side of the open mouth 113 away from the first containing area 131. It can be understood that in the first use state, the plug part 212 is located outside the open mouth 113, that is, the plug part 212 is located outside the shell 1, thereby facilitating the plug part 212 to be connected with other electronic equipment, and improving the convenience and compatibility of the charging device in use.

[0044] For example, the space surrounded by the open mouth 113 can constitute the entire second containing area 132.

[0045] For another example, the space surrounded by the open mouth 113 constitutes part of the second containing area 132, and the other part of the second containing area 132 is located inside the shell 1.

[0046] Optionally, the housing 1 includes an outer shell 11 and a fixing frame 12. The fixing frame 12 is disposed inside the outer shell 11 and has a receiving groove 121. The receiving groove 121 forms a first receiving area 131 and at least a portion of a second receiving area 132. An opening 113 is disposed on the outer shell 11 and is arranged opposite to the receiving groove 121. It is understood that a portion of the second receiving area 132 is formed within the opening 113, and another portion of the second receiving area 132 is formed within the receiving groove 121. The first receiving area 131 is located at the bottom of the receiving groove 121, which facilitates the processing and manufacturing of the housing 1 and provides better protection for the plug portion 212.

[0047] Optionally, the housing 1 is provided with a snap-fit ​​part 14, which engages with the charging base 211 in at least one of the storage state and the first use state. It can be understood that the charging base 211 can engage with the snap-fit ​​part 14 in both the storage state and the first use state of the charging head 21, thereby facilitating the fixation of the charging head 21 and providing a simple structural design that is easy to assemble and disassemble.

[0048] For example, the snap-fit ​​portion 14 is along the second direction (e.g. Figure 7 The charging head 21 is positioned on at least one side of the storage area 13 in the left-right direction, with the first direction orthogonal to the second direction. It is understood that the insertion and removal direction of the charging head 21 can be arranged orthogonally to the direction in which the locking force is applied by the latching part 14, thereby further improving the stability of the charging head 21 in the storage state or the first use state.

[0049] like Figures 6 to 8 As shown, the receiving groove 121 on the mounting bracket 12 has a contoured cavity that is substantially the same in shape as the plug portion 212. In the retracted state, the plug portion 212 extends toward the bottom of the receiving groove 121 and fits within the contoured cavity (i.e., the receiving groove 121) enclosed by the mounting bracket 12, thereby improving the stability of the charging head 21 after it is retracted.

[0050] like Figures 6 to 8 As shown, the snap-fit ​​portion 14 is provided on at least one of the housing 11 and the mounting bracket 12. For example, both the housing 11 and the mounting bracket 12 are provided with snap-fit ​​portions 14 to improve the secure installation of the charging head 21.

[0051] Optionally, such as Figure 4 and Figure 5 As shown, the latching part 14 includes a latch 141, which is disposed on the housing 11. The charging base 211 has a wiring segment 2113, which is latched with the latch 141. It can be understood that the wiring segment 2113 of the charging base 211 is connected to the cable 22, and the latch 141 can be elastically latched with the wiring segment 2113, thereby fixing the connection position of the cable 22 and the charging base 211 to improve the firmness of the connection between the connector 2 and the housing 1.

[0052] For example, as shown in Figure 4 and Figure 5 The buckle 141 includes two clamping protrusions arranged on both sides of the width direction of the wiring groove 114, and the wiring segment 2113 of the charging base 211 is clamped between the two clamping protrusions to fix the charging base 211.

[0053] Optionally, as shown in Figure 4 , Figure 7 and Figure 8 The clamping portion 14 further includes a spring sheet 142 arranged in the accommodating groove 121, and the spring sheet 142 elastically abuts against the charging base 211. It can be understood that by arranging the spring sheet 142 in the accommodating groove 121, on the one hand, the clamping structure of the clamping portion 14 can be hidden, so that the appearance of the charging device is beautiful and the integrity is good. On the other hand, the degree of integration of the charging device can be improved, and the mounting structure of the charging head 21 is more compact.

[0054] For example, the spring sheet 142 can be a metal spring sheet 142, which clamps the charging base 211 by using the elastic force of the metal spring sheet 142 itself.

[0055] In the examples of the present application, the spring sheet 142 is two, and the two spring sheets 142 are arranged on opposite sides of the charging base 211. The two spring sheets 142 can jointly clamp and fix the charging base 211 to further improve the stability of the charging head 21 after installation.

[0056] For example, as shown in Figure 4 and Figure 5 The side wall of the charging base 211 is provided with a groove 2114, and the spring sheet 142 elastically abuts against the groove 2114. It can be understood that the position where the charging base 211 abuts against the spring sheet 142 is recessed inward to form the groove 2114. On the one hand, the abutting structure of the groove 2114 and the spring sheet 142 can positionally constrain the fixed charging base 211, and on the other hand, when the charging base 211 is disassembled, the spring sheet 142 will produce a "click" sound due to disengagement or clamping into the groove 2114, so as to prompt the user that the charging base 211 is installed in place, thereby improving the user experience.

[0057] As shown in Figure 8 The shell 1 further includes a fastener 15, and the spring sheet 142 is detachably connected with the fixing frame 12 through the fastener 15. For example, the fastener 15 is a screw, and the spring sheet 142 is connected with the fixing frame 12 through the screw, which can facilitate the installation and disassembly of the spring sheet 142.

[0058] For example, as shown in Figure 7As shown, the fixing frame 12 is also connected with the shell 1 by screws, so that the operator can assemble the shell 1 and the fixing frame 12. The shell 1 comprises a first half shell 111 and a second half shell 112, which can be connected by clamping, bonding or screwing to enclose a cavity for accommodating the battery cell 3 and the fixing frame 12.

[0059] In some embodiments, as shown in Figure 4 , Figure 6 and Figure 8 , the shell 1 further comprises a moving button 16 having a stop portion 161, and the charging seat 211 has a boss 2115, the moving button 16 being slidable relative to the outer shell 11 between a locking position and a release position, in the locking position, the stop portion 161 is pressed on the boss 2115 to limit the charging seat 211 from being separated from the outer shell 11, and in the release position, the stop portion 161 is spaced apart from the boss 2115. It can be understood that when the moving button 16 is moved to the locking position, the stop portion 161 can be pressed on the boss 2115, and under the constraint of the stop portion 161, the charging seat 211 will not be separated from the receiving area 13, thereby ensuring the firmness of the installation of the charging head 21 and avoiding the risk of loosening of the charging head 21 from the shell 1.

[0060] In addition, when it is necessary to separate the charging head 21 from the shell 1, the user can slide the moving button 16 to the release position, at which time the stop portion 161 is spaced apart from the boss 2115, and the user can pull the charging head 21 with a little force to pull it out.

[0061] In some embodiments, as shown in Figure 8 , the shell 1 further comprises a resilient member 17 connected with the fixing frame 12 and the moving button 16, the resilient member 17 having an elastic force for driving the moving button 16 to move from the release position to the locking position. It can be understood that after the user slides the moving button 16 to the release position, the resilient member 17 can drive the moving button 16 to automatically return to the locking position, on the one hand, it can improve the convenience of the user during use, and the operation is convenient. On the other hand, since the resilient member 17 has an elastic force for driving the moving button 16 to move from the release position to the locking position, the probability of the moving button 16 moving to the release position due to accidental touch can be reduced, which is beneficial to improve the reliability of the fixation of the charging head 21.

[0062] Optionally, as shown in Figures 1 to 3 , the connector 2 further comprises a cable 22, one end of the cable 22 being electrically connected with the battery cell 3, and the other end of the cable 22 being electrically connected with the charging head 21, the charging head 21 further having a second use state, in the second use state, the charging head 21 is separated from the shell 1. It can be understood that the user can select different charging modes according to the actual use scene to expand the application range of the charging equipment.

[0063] In some embodiments, the charging device has different charging modes as follows:

[0064] The first use state (as shown in FIG. 2A) : the user fixes the charging base 211 at the open port 113, and the plug portion 212 extends out of the storage area 13, and the plug portion 212 is directly connected to the mobile terminal, so that the user can use the charging device without holding it. Figure 2 The second use state (as shown in FIG. 2B) : the user can take out the charging head 21 from the storage area 13, so that the charging head 21 is not connected to the shell 1, and the user can separate the mobile terminal from the shell 1 by a certain distance, for example, the charging device (the shell 1) can be placed on a table or in a pocket, and used as a common charging device.

[0065] Figure 3 In other examples, the charging device can also not be designed with the cable 22, that is, the charging head 21 can be directly electrically connected to the circuit board in the shell 1.

[0066] Optionally, as shown in FIG. 2C, the shell 1 is provided with a wiring groove 114, and at least part of the cable 22 is arranged in the wiring groove 114, and the wiring groove 114 is in communication with the open port 113. The wiring groove 114 can arrange the cable 22, so as to further reduce the occupied space of the charging device. Since the wiring groove 114 is in communication with the open port 113, the user can pull the cable 22 to take out the charging head 21 from the storage area 13, so as to facilitate the daily use of the user.

[0067] For example, the wiring groove 114 can be arranged on one wall surface of the shell 1, or arranged on multiple wall surfaces of the shell 1, and the arrangement path and arrangement position of the wiring groove 114 are not limited in the present application. Figures 1 to 3 As shown in FIG. 2D and FIG. 2E, the charging base 211 has a first wall surface 2111 away from the plug portion 212 and a second wall surface 2112 adjacent to the plug portion 212. In the storage state, the first wall surface 2111 is flush with the open port 113, and in the first use state, the second wall surface 2112 is flush with the open port 113. It can be understood that after the charging head 21 is stored, the outer wall surface (the first wall surface 2111) of the charging base 211 is flush with the outer wall surface (the end surface of the open port 113) of the shell 1, so that the appearance of the charging device after storage is more regular, has better integrity, and has an attractive appearance.

[0068]

[0069] Figure 1 Figure 2 It can be understood that after the charging head 21 is stored, the outer wall surface (the first wall surface 2111) of the charging base 211 is flush with the outer wall surface (the end surface of the open port 113) of the shell 1, so that the appearance of the charging device after storage is more regular, has better integrity, and has an attractive appearance.

[0070] ​​​​When the charging head 21 is fixed at the position of the open hole 113 (i.e. the first use state), at this time, the charging seat 211 is clamped with the fixed frame 12, and the outer wall surface (the second wall surface 2112) of the charging seat 211 is flush with the outer wall surface (the end surface of the open hole 113) of the shell 1, so that the charging equipment in this use state occupies a smaller space, has a beautiful appearance, and has better integrity.
