DETAILED DESCRIPTION

[0036] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] like Figures 1 to 5 As shown, one embodiment of the present invention provides a pop-up charger, comprising a housing 1 and a base 2, a plug 3, an elastic member 35, a first stopper 8, a second stopper 5, and a third stopper 6, all disposed within the housing 1. The plug 3 is slidably connected to the base 2, sliding along a first direction between a first position and a second position. The plug 3 includes a pin 33 extending along the first direction, which is configured to plug into a socket. The elastic member 35 is configured to provide a tendency for the outer end of the pin 33 to pass through the housing 1. The first stopper 8 is disposed on the plug 3. The second stopper 5 and the third stopper 6 are each rotatably connected to the base 2.

[0038] Reference Figure 3When the plug 3 is in the first position, the plug 3 extends out of the housing 1 and can be connected to an external device. At this time, the second stopper 5 and the first stopper 8 engage to keep the plug 3 in the first position, that is, the plug 3 is always extended out of the housing 1.

[0039] Reference Figure 4 , the plug 3 moves from the first position to the second position, retracts into the housing 1, and the first stopper 8 disengages from the second stopper 5 and moves toward the third stopper 6 until the third stopper 6 and the first stopper 8 engage. Under the action of an external force, the second stopper 5 disengages from the first stopper 8. At this time, the elastic member 35 drives the plug 3 toward the second position, and the third stopper 6 moves along with the plug 3 toward the second position. After the plug 3 moves to the second position, the third stopper 6 and the first stopper 8 engage. During this process, the plug 3 gradually enters the housing 1. The engagement between the third stopper 6 and the first stopper 8 keeps the plug 3 in the second position.

[0040] In this embodiment, two or three pins are provided, and the two or three pins are parallel to each other.

[0041] Reference Figure 2 In this embodiment, the pop-up charger further includes a button 41 and a spring 42. A key hole 13 is provided on the housing 1. The key hole 13 penetrates a side wall of the housing 1 along the second direction. The button 41 slides in the key hole 13.

[0042] The second limiting member 5 and the third limiting member 6 are both disposed between the button 41 and the base 2. The second limiting member 5 has a first end 51 and a second end 52 that are oppositely disposed. The rotation axis of the second limiting member 5 is disposed between the first end 51 and the second end 52. The first end 51 is adapted to engage with the first limiting member 8 for blocking, and the second end 52 abuts against the button 41.

[0043] The third limiting member 6 has a third end 61 and a fourth end 62 arranged opposite to each other, and the rotation axis of the third limiting member 6 is set between the third end 61 and the fourth end 62. The third end 61 is suitable for blocking and cooperating with the first limiting member 8, and the fourth end 62 abuts against the button 41.

[0044] A first return member 53 is disposed between the first end 51 and the base 2. The first return member 53 is elastic, allowing the first end 51 to move toward the first stopper 8. A second return member 63 is disposed between the fourth end 62 and the base 2. The second return member 63 is elastic, allowing the fourth end 62 to move toward the first stopper 8. In this embodiment, the second stopper 5 can drive the first end 51 toward the first stopper 8 via the first return member 53 in the absence of external force, thereby enabling a snap-fit ​​engagement with the first stopper 8. Similarly, the fourth end 62 can snap-fit ​​engagement with the first stopper 8 under the drive of the second return member 63. Both the first return member 53 and the second return member 63 are compressed springs 42. One end of the first return member 53 is fixed to the base 2, and the other end is fixed to the first end 51. One end of the second return member 63 is fixed to the base 2, and the other end is fixed to the fourth end 62.

[0045] Reference Figure 3 and Figure 4 In this embodiment, the second limiting member 5 and the third limiting member 6 are both rod-shaped. The rotation axis of the second limiting member 5 for rotational connection with the base 2 is set in the middle of the second limiting member 5. Similarly, the rotation axis of the third limiting member 5 and the base 2 is set in the middle of the third limiting member 6. The working state of the second limiting member 5 and the third limiting member 6 is the same as that of a seesaw. When the second end 52 is pressed toward the base 2, the first end 51 moves in a direction away from the base 2. When an external force is applied to the plug 3 to retract the shell 1, the plug 3 can be driven into the shell 1; when the third end 61 is pressed toward the base 2, the fourth end 62 moves in a direction away from the base 2. At this time, the elastic member 35 drives the plug 3 to move out of the shell 1 and pass through the shell 1.

[0046] The spring 42 is arranged between the base 2 and the button 41. The spring 42 expands and contracts along the second direction so that the button 41 tends to move away from the base 2. There is a non-zero angle between the first direction and the second direction.

[0047] In combination with the movement process of the second limit member 5 and the third limit member 6, when the plug 3 is in the second position, press the button 41 to move the button 41 toward the base 2. At this time, the second end 52 and the third end 61 move toward the base 2, and the first end 51 and the fourth end 62 move away from the base 2. The first limit member 8 does not cooperate with the second limit member 5 and the third limit member 6. The base 2 moves toward the first position driven by the elastic member 35, and directly passes through the shell 1 without any interference during the movement. When the base 2 moves to the first position, release the button 41, and the first end 51 and the first limit member 8 cooperate to keep the plug 3 from passing through the shell 1.

[0048] When the plug 3 is in the first position, the button 41 is pressed, the first end 51 and the first limit member 8 are disengaged, and an external force is applied to the plug 3 to drive the plug 3 to move toward the shell 1, so that the plug 3 moves from the first position to the second position. When the plug 3 completely enters the shell 1, the plug 3 is in the second position. At this time, the button 41 is released, and the button 41 moves in the direction away from the base 2. At this time, the fourth end 62 and the first end 51 move toward the base 2, and the fourth end 62 and the first limit member 8 are blocked and cooperated to keep the plug 3 in the shell 1.

[0049] As an example, the first end 51, the second end 52, the third end 61 and the fourth end 62 are collinear, the second end 52 and the third end 61 are close to each other, the first end 51 is located on the side of the second end 52 away from the third end 61, and the fourth end 62 is located on the side of the third end 61 away from the second end 52; a protrusion is provided on the side of the button 41 close to the base 2, and the protrusion abuts the second end 52 and the third end 61.

[0050] In this embodiment, in order to shorten the moving path of the button 41 , a protrusion is provided on the button 41 , and the protrusion is used to simultaneously control the movement of the second end 52 and the third end 61 .

[0051] In this embodiment, a limiting hole is provided on the plug 3, which passes through the plug 3 along the second direction and constitutes a first limiting member 8. Two second limiting members 5 and two third limiting members 6 are provided, respectively. The two second limiting members 5 are provided on either side of the plug 3 along the second direction. The two second limiting members 5 are arranged relative to each other so that their first ends 51 are symmetrically arranged with respect to the base 2. When the plug 3 moves to the first position, the first ends 51 of the two second limiting members 5 simultaneously engage with the limiting hole. Similarly, two third limiting members 6 are provided on either side of the plug 3 along the second direction. The two third limiting members 6 are arranged relative to each other so that their fourth ends 62 are symmetrically arranged with respect to the base 2. When the plug 3 moves to the second position, the two third limiting members 6 simultaneously engage with the limiting hole.

[0052] Reference Figure 2 and Figure 3 There are two buttons 41, and the two buttons 41 are arranged on both sides of the base 2 along the second direction; the multiple springs 42 are divided into multiple first springs 42 and multiple second springs 42, and the multiple first springs 42 are arranged between one of the buttons 41 and the base 2, and the multiple second springs 42 are arranged between the other button 41 and the base 2.

[0053] In this embodiment, multiple first springs 42 are arranged on one side of the base 2, and multiple second springs 42 are arranged on the other side of the base 2. The multiple first springs 42 are used to provide a tendency for the buttons 41 on one side to move away from the base 2, and the second springs 42 are used to provide a tendency for the buttons 41 on the other side to move away from the base 2.

[0054] As an example, the plug 3 further includes a guide rod 31 and a base plate 32. A pin 33 and an elastic member 35 are disposed on either side of the base plate 32 along a first direction. The pin 33 is used to connect to the socket, and two pins 33 are provided. The base plate 32 is provided with a guide hole extending along the first direction. One end of the guide rod 31 is fixed to the base 2, while the other end of the guide rod 31 passes through the guide hole and extends through the base plate 32. The elastic member 35 is a compression spring 42, which is sleeved on the guide rod 31. One end of the elastic member 35 abuts the base plate 32, and the other end abuts the base 2.

[0055] Two guide rods 31 are provided, and the two guide rods 31 are arranged in parallel to allow the seat plate 32 to move smoothly along the guide rods 31. Two guide holes are also provided accordingly, and the elastic member 35 provides power to the seat plate 32 to move toward the direction of passing through the shell.

[0056] As an example, the pop-up charger further includes a circuit board 7 and two connecting bars 71. The circuit board 7 is disposed within the housing 1, with one side of the circuit board 7 fixed to the housing 1. The two connecting bars 71 are respectively fixed to opposite sides of the circuit board 7 in the third direction, and the connecting bars 71 extend along the first direction. The plug 3 further includes two connecting pieces 34, which are fixed to opposite sides of the pins 33 in the third direction. Each connecting piece 34 slides on a connecting bar 71, and the connecting pieces 34 are respectively electrically connected to the connecting bar 71 and the pins 33. The first direction, the second direction, and the third direction are perpendicular to each other.

[0057] In this embodiment, the electrical connection between the pins 33 and the circuit board 7 is achieved through the connection bar 71 and the connection piece 34. The connection bar 71 is fixed, but the connection piece 34 can slide relative to the connection bar 71, so that the connection piece 34 can move with the pins 33. Compared with using a long wire to maintain the connection between the pins 33 and the circuit board 7, long wires are prone to getting tangled or moving to other locations. In this embodiment, the connection piece 34 and the connection bar 71 can avoid the problem of long wires.

[0058] As an example, the base 2 includes a first sub-base 21 and a second sub-base 22. The first sub-base 21 is provided with a first groove 23, and the second sub-base 22 is provided with a second groove 24.

The second groove 24 has a fourth opening, a fifth opening, and a sixth opening. The fifth opening and the sixth opening are arranged on opposite sides of the second sub-base 22. The first opening and the fourth opening are opposite and connected to form a cavity for placing the plug 3. The second opening and the fifth opening are opposite and connected to form a first side opening. The third opening and the sixth opening are opposite and connected to form a second side opening.

[0059] One side of the seat plate 32 slides in the first side opening, and the other side of the seat plate 32 slides in the second side opening.

[0060] The first sub-base 21 is provided with a first socket, which extends along the second direction and communicates with the first groove 23. The first socket directly faces the keyhole 13, and a protrusion on one of the keys 41 extends from the socket into the first groove 23. Similarly, the second sub-base 22 is provided with a second socket, which extends along the second direction and communicates with the first groove 23. The second socket directly faces the keyhole 13, and a protrusion on another key 41 extends from the socket into the first groove 23.

[0061] The first sub-base 21 and the second sub-base 22 are symmetrically and detachably connected to form the base 2, so that the plug 3 can be assembled into the base 2. In this embodiment, the two pins 33 are arranged on opposite side walls of the base plate 32 and are located outside the base 2. Therefore, a second opening and a third opening are provided on the first sub-base 21, and a fifth opening and a sixth opening are provided on the second sub-base 22. The above-mentioned openings are used to accommodate the pins 33 on the outside of the base 2.

[0062] Reference Figure 2 As an example, the housing 1 includes a housing body 11 and an end cap 12. The housing body 11 has a cavity, is closed at one end in a first direction, and forms an opening at the other end in the first direction, into which the end cap is inserted.

In actual use, the first through hole 18 and the second through hole 19 can pass through the pin 33. In this embodiment, the housing 1 is also formed by the housing body 11 and the end cap 12, which are detachably connected. This also facilitates the assembly of the base 2 and the plug 3 into the housing 1.

[0063] Reference Figure 5As an example, a first male buckle 14 is provided on the end cap 12, a second male buckle 15 is provided on the inner wall of the shell body 11, and a first female buckle 27 and a second female buckle 28 are provided on the seat plate 32.

Similarly, the two second male buckles 15 on the same side of the shell 1 are snap-connected to the second female buckle 28 on the first sub-base 21, and the two second male buckles 15 on the other side of the shell 1 are used to snap-connect to the second female buckle 28 on the second sub-base 22 to fix the base 2 in the shell 1.

[0064] As an example, a first insertion groove 16 and a second insertion groove 17 are respectively provided on opposite sides of the end cap 12. The first insertion groove 16 and the second insertion groove 17 both extend along a first direction. One connecting strip 71 is inserted into the first insertion groove 16, and the other connecting strip 71 is inserted into the second insertion groove 17. The first insertion groove 16 and the second insertion groove 17 can prevent the connecting strip 71 from moving freely and thus stabilize it. They also serve to determine the installation position of the connecting strip 71 during assembly and provide a positioning function.

[0065] In this embodiment, the first insertion groove 16 is formed by two L-shaped plates fixed to the end plate at intervals. The first insertion groove 16 has two openings, one of which faces the center of the end cap 12 and the other faces the housing 1. The connecting strip 71 is inserted into the end cap 12 through the opening facing the housing 1.
