[0002] Charging docks are typically used in vehicles to charge electronic devices. Since vehicles inevitably experience up-and-down bumps and side-to-side swaying during driving, in order to ensure that the electronic devices maintain a stable electrical connection with the charging dock throughout the charging process, the charging dock needs to have an anti-detachment function to prevent the electronic devices from falling out of the charging dock. At the same time, in order to allow the electronic devices to be quickly and smoothly removed from the charging dock after charging is completed, the anti-detachment function needs to be able to be quickly released.

[0003] In related technologies, the charging dock achieves anti-detachment and quick detachment through two states of the locking mechanism. However, the locking mechanism has problems such as poor stability of the locking state, inability to quickly release the locking state, and inconvenient operation steps for releasing the locking state.

[0025] like Figures 1 to 10As shown, this embodiment provides a charging dock for charging an electronic device 60, including a housing. The housing includes a back panel 10, a surrounding panel 20, and a base 30. The back panel 10, the surrounding panel 20, and the base 30 form a mounting position for mounting the electronic device 60 and a charging position for charging the electronic device 60. The electronic device 60 includes a first end located at the bottom and a second end located at the top. When the electronic device 60 is located in the mounting position, the first end of the electronic device 60 is located inside the base 30, and the electronic device is located outside the surrounding panel 20, forming a mounting space between it and the back panel 10. When the electronic device 60 is located in the charging position, the first end of the electronic device 60 is located inside the base 30, and the electronic device 60 is limited by the surrounding panel 20 and the back panel 10. When the first end of the electronic device 60 is located inside the base 30, and the electronic device 60 rotates with its first end as the center of rotation, the electronic device 60 can move and switch between the mounting position and the charging position.

[0026] In use, first insert the first end of the electronic device 60 into the base tray 30 and place the electronic device 60 at an angle on the base tray 30, so that the electronic device 60 enters the mounting position. Then, push the second end of the electronic device 60, so that the electronic device 60 rotates around the first end as the rotation center in the direction of the back stop 10, and moves from the mounting position into the charging position. Similarly, after the electronic device 60 has finished charging, push the second end of the electronic device 60, so that the electronic device 60 rotates around the first end as the rotation center in the direction away from the back stop 10, so that the electronic device 60 moves from the charging position into the mounting position. Then, remove the electronic device 60 from the mounting position along the tilt direction of the electronic device. Through the above settings, the charging stand of this embodiment realizes the quick insertion and removal of the electronic device 60, and the disassembly and assembly process is simple and easy to use.

[0027] In some embodiments, such as Figure 1 , 5 As shown in Figure 8, the housing is provided with an elastic locking assembly 40; the elastic locking assembly 40 has a first guide surface 4222, the first guide surface 4222 is adapted to the electronic device, so that when the electronic device moves from the mounting position to a certain position of the charging position with its first end as the rotation center, it can squeeze the first guide surface 4222 to retract the elastic locking assembly, and when the electronic device moves to the charging position, the elastic locking assembly 40 extends, so that the elastic locking assembly 40 can limit the electronic device after the electronic device enters the charging position.

[0028] In some embodiments, such as Figure 1 , 5As shown in Figure 8, the housing is provided with an elastic locking assembly 40; the elastic locking assembly 40 has a second guide surface 4221, which is adapted to the electronic device so that when the electronic device moves from the charging position to a certain position of the mounting position with its first end as the rotation center, it can squeeze the second guide surface to retract the elastic locking assembly 40, so that the electronic device can be disengaged from the charging position and moved to the mounting position. This facilitates the user to remove the electronic device.

[0029] Specifically, such as Figure 1 As shown, the enclosure 20 is located on both sides of the back wall 10 and extends along the first direction ( Figure 1 (As shown in the X direction), the enclosure 20 is used to clamp the electronic device, the base 30 is fixedly connected to the back block 10 and located below the enclosure 20, and the base 30 is used to support the electronic device; an elastic locking assembly 40 is provided inside the enclosure 20, the accommodating space above the base 30 and located between the elastic locking assemblies 40 is set as the charging position, and the accommodating space above the base 30 and located on the outer side of the elastic locking assembly 40 along the first direction is set as the mounting position. When the electronic device 60 is in the charging position, the back block 10 abuts against the surface of the electronic device 60, and enclosures 20 are respectively provided on both sides of the back block 10 to clamp the electronic device 60, and the base 30 is fixedly connected to the back block 10 and used to support the electronic device 60; when the electronic device 60 is installed in the charging position, the back block 10 fits against the back side of the electronic device 60, and the enclosure 20 is connected to the back block 10. Figure 2 The bottom support 30 is connected to the lower section of the back panel 10 near the bottom, located on the left and right sides in the direction shown, and is located on the upper section near the top of the back panel 10. The bottom support 30 extends outward from the lower left and lower right corners of the back panel 10 to wrap and support the two bottom corners of the electronic device 60.

[0030] Specifically, when the electronic device 60 is located in the charging position, the elastic locking assembly 40 extends from the enclosure 20 and limits the electronic device 60; part of the elastic locking assembly 40 is connected to the inside of the housing, and part extends out of the housing and engages with the electronic device 60 to ensure that the electronic device 60 is stably installed on the charging base; the back cover 10 is provided with a charging contact 11, which is used to electrically connect with and charge the electronic device 60 when it is located in the charging position. The electronic device 60 has a charging interface on its back side that mates with the charging contact 11. The charging contact 11 is formed as a protrusion extending in the direction of the electronic device 60, so that the charging contact 11 can be inserted into the charging interface to electrically connect with the electronic device 60 and charge the electronic device 60. In this embodiment, the back cover 10, the enclosure 20, and the base 30 are integrated into one structure to improve the structural stability of the charging base. In other embodiments, the back cover 10, the enclosure 20, and the base 30 can also be configured as separate connection structures, connected by a fixed connection method such as snap-fit ​​or plug-in to form a whole.

[0031] In this embodiment, the back block 10, the enclosure 20, and the base support 30 limit the electronic device 60 from different directions. Specifically, the back block 10 limits the back side of the electronic device 60, the enclosure 20 limits the left and right sides of the electronic device 60 to prevent the upper part of the electronic device 60 from coming off from the left and right sides, the elastic locking assembly 40 on the enclosure 20 limits the front side of the electronic device 60 to prevent the upper part of the front side of the electronic device 60 from tilting forward and coming off the mounting base 41, and the base support 30 limits the two bottom corners of the electronic device 60 to prevent the bottom of the electronic device 60 from coming off the base support 30 from the front and left and right sides. The above settings ensure that the connection between the electronic device 60 and the charging base is stable during the charging process, and prevent the electronic device 60 from coming off the charging base due to vehicle bumps.

[0032] In some embodiments, such as Figure 1 , 2 As shown in Figure 3, the back panel 10 is provided with an anti-detachment protrusion 12 extending towards the charging position. The top of the anti-detachment protrusion 12 is provided with a magnet 121 for adsorbing the electronic device 60. The anti-detachment protrusion 12 protrudes from the surface of the back panel 10, and the magnet 121 is located on the top of the anti-detachment protrusion 12. When the electronic device 60 is located in the charging position, the anti-detachment protrusion 12 can be inserted into the corresponding position in the electronic device 60, so that the magnet 121 on the top of the anti-detachment protrusion 12 can adsorb the magnet 121 or iron piece located at the corresponding position on the electronic device 60, further improving the stability of the installation connection between the charging base and the electronic device 60, and preventing the electronic device 60 from detaching from the charging base through the upper opening of the charging base.

[0033] In some embodiments, such as Figure 5 , 6 As shown, the elastic locking assembly 40 includes a mounting base 41, a locking buckle 42, and an elastic element 43. The locking buckle 42 is provided with a rotating shaft 421, and the locking buckle 42 is hinged to the mounting base 41 via the rotating shaft 421, allowing the locking buckle 42 to rotate along the rotating shaft 421 and form a reset state and a rotating state. The elastic element 43 is located between the locking buckle 42 and the mounting base 41, allowing the locking buckle 42 to extend from the enclosure 20 and limit the electronic device 60 in the reset state. Specifically, as... Figure 5 As shown, the latch 42 is located inside the mounting base 41 and can rotate within a certain range along the rotating shaft 421. When the latch 42 is in the reset state, under the pushing force of the elastic member 43, the other side of the latch 42 relative to the rotating shaft 421 can protrude from the surface of the enclosure 20 and abut against the electronic device 60. During the process of the electronic device 60 being inserted into and removed from the charging base, the side wall of the electronic device 60 abuts against and pushes the latch 42 toward the side where the elastic member 43 is located. After the electronic device 60 is completely inserted into or removed from the charging base, the latch 42 returns to the reset state.

[0034] Specifically, such as Figure 1 , 2 As shown in Figure 4, the latch 42 also has a latch 422. The pivot 421 and the latch 422 are located at both ends of the latch 42. The side surface of the enclosure 20 facing the charging position has a through hole, and the latch 422 can extend from the through hole to the charging position. By setting the pivot 421 and the latch 422 at both ends of the latch 42, and by reasonably setting the length of the latch 42 body and the position and elasticity of the elastic element 43, the force required for the electronic device 60 to be inserted into and removed from the charging base is more appropriate.

[0035] In some embodiments, such as Figure 8As shown, the latch 422 has a first guide surface 4222 and a second guide surface 4221, which facilitates the insertion of the electronic device 60 into the charging position along the first guide surface 4222 and its removal from the charging position along the second guide surface 4221. During the insertion of the electronic device 60 into the charging position, its two side walls abut against the first guide surface 4222 of the latch 422 and are inserted into the charging position along the guiding direction of the first guide surface 4222. During the removal of the electronic device 60 from the charging position, its two side walls abut against the second guide surface 4221 of the latch 422 and are removed from the charging position along the second guide surface 4221. By providing the second guide surface 4221 and the first guide surface 4222 on the latch 422, the process of inserting and removing the electronic device 60 from the charging position is made more convenient and smooth.

[0036] In some embodiments, such as Figure 6 , 7 As shown, the latch 42 is also provided with a hook 423, which is used to position the latch 42 in its reset state. When the latch 42 is in the reset state, the hook 423 abuts against the mounting base 41 to prevent the latch 42 from moving excessively under the action of the elastic member 43.

[0037] In some embodiments, such as Figures 1 to 4 As shown, a baffle 31 is formed on the base 30 opposite to the back baffle 10. When the electronic device 60 is located in the charging position, its bottom end is clamped between the baffle 31 and the back baffle 10. In this embodiment, the bottom end of the electronic device 60 is located between the base 30 and the back baffle 10 and can rotate within a certain range. For example, the electronic device 60 can be positioned within the mounting base 41 as follows: Figure 9 , Figure 10 The two states shown.

[0038] In some embodiments, such as Figure 3 , 4 As shown, the baffle 31 has a baffle 32 extending toward the back block 10 on one side surface facing the back block 10. The baffle 32 has several pieces arranged in parallel, and the baffle 32 is arranged perpendicular to the front side wall of the electronic device 60 to form a stable support for the front side of the electronic device 60 and prevent the lower part of the electronic device 60 from coming out of the charging base.

[0039] Specifically, such as Figure 7 , 8 As shown, the elastic element 43 is a compression spring, and the latch 42 is a sheet-shaped elastic latch 42.

[0040] In some embodiments, the charging contact 11 is configured as an elastic contact, and a circuit board 50 is disposed inside the housing, with the elastic contact electrically connected to the circuit board 50.

[0041] like Figure 9 , 10 As shown, in this embodiment, the process of inserting the electronic device 60 into the charging dock includes the following steps: Figure 9 The intermediate states shown and as Figure 10 As shown in the completed state, during the process of inserting the electronic device 60 into the charging dock, first, the bottom of the electronic device 60 is positioned as follows: Figure 9 Place the electronic device 60 onto the base 30 of the charging dock in the direction indicated by the middle arrow, so that the electronic device 60 is in the mounting position, and then... Figure 10 The electronic device 60 is pushed towards the back stop 10 in the direction indicated by the middle arrow, so that both sides of the electronic device 60 are clamped between the locking tongue 422 of the elastic locking assembly 40 and the back stop 10, so that the electronic device 60 enters the charging position, and the elastic locking assembly 40 prevents the electronic device 60 from moving along the back stop 10. Figure 10 The electronic device 60 is dislodged from the charging base in the opposite direction of the arrow shown, and the anti-dislodgement protrusion 12 and magnet 121 prevent the electronic device 60 from dislodging from the top of the charging base, so as to realize the anti-dislodgement function of the charging base for the electronic device 60.

[0042] In summary, the charging dock provided in the above embodiments can improve the connection stability of the electronic device 60 during the charging process, prevent the electronic device 60 from detaching from the charging dock, and is convenient and easy to use when inserting and removing the electronic device 60.

[0043] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Those skilled in the art should understand that this application includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this application will be included within the scope of the claims.
