[0030] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application 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 this application and are not intended to limit this application.

[0032] Reference Figures 1 to 6 In one embodiment of the present invention, a flip-type portable charger is proposed, including a battery compartment 1 for installing a battery, a power access port is provided on one end face of the battery compartment 1, and an open end begins on the other end face, a charging mainboard 11 connected to the power access port is provided inside the battery compartment 1, a battery slot 12 is provided between the charging mainboard 11 and the open end, a flip structure 4 is rotatably connected to one side of the open end, the flip structure 4 is provided with a locking structure 5 relative to the battery compartment 1, a charging module 2 is provided between the flip structure 4 and the charging mainboard 11, the charging module 2 is electrically connected to the charging mainboard 11 and wrapped around the battery slot 12, and the charging module 2 is provided with a switch structure relative to the flip structure 4.

[0033] The flip cover structure 4 is rotatably connected to the top of the battery compartment 1, and the power access port is opened at the bottom of the charging compartment. The battery is inserted into the battery slot 12 along the open end toward the power access port, so that the battery electrodes can be stably connected to the charging motherboard 11, making the battery charging more stable.

[0034] The flip cover structure 4 is rotatably connected to the battery compartment 1, and is provided with a locking structure 5 relative to the battery compartment 1. The locking structure 5 can ensure the stability of the battery placement when the battery is installed in the battery compartment 1, and the battery can be directly placed in the battery compartment 1 during transportation to make it easy to carry. The flip cover structure 4 itself is easy to disassemble and install, which can facilitate the use of the battery compartment 1.

[0035] A charging module 2 is provided between the charging mainboard 11 and the flip structure 4, including a positive charging electrode and a negative charging electrode, both of which are connected to the charging mainboard 11 and are uniformly controlled by the charging mainboard 11 for charging. At least one group of electrodes is connected to the bottom surface of the flip structure 4. The charging mainboard 11 is provided with a switch structure facing the flip structure 4, and the two electrodes are connected by means of the switch structure. Generally, the switch structure is a circuit that can only be activated when the flip structure 4 is closed. The charging mainboard 11 starts after receiving the activation command, which can ensure the stability of the charger.

[0036] See also Figures 2 to 4 In one embodiment of the present application, a positive electrode spring clip 21 is provided at one end of the charging module 2 facing the charging mainboard 11, and a negative electrode hardware 22 is provided at one end of the charging module 2 facing the flip cover structure 4; when the locking structure 5 is snapped into the battery compartment 1, the negative electrode hardware 22 is arranged opposite the positive electrode spring clip 21.

[0037] Because the battery has positive and negative poles, the positive charging pole of the charger needs to correspond to the positive pole of the battery, and the negative charging pole needs to correspond to the negative pole of the battery in order to charge the battery normally. The battery itself is generally provided with a connector at the positive pole to distinguish the positive and negative poles. In order to ensure the stability of charging, a restrictive structure needs to be designed in the battery compartment 1. Compared with the negative pole, the end with the positive pole connector is easier to design. It is only necessary to recess the positive charging pole inward at the position corresponding to the positive pole. Only the positive pole connector can be extended into and connected to the positive charging pole, so as to prevent reverse connection.

[0038] In this application, the battery needs to be inserted into the battery compartment 1 before the flip cover structure 4 is closed. One of the pins of the battery will first contact the bottom of the battery compartment 1. In order to protect the battery, preferably, the positive electrode spring 21 is arranged at one end of the charging motherboard 11, and the negative electrode hardware 22 is connected to the flip cover structure 4.

[0039] See also Figures 1 to 2 In one embodiment of the present application, the battery compartment 1 is provided with a heat dissipation window toward the battery slot 12 , and a baffle 13 is provided at one end of the battery slot 12 toward the charging motherboard 11 . The baffle 13 is wrapped around the positive electrode spring piece 21 , and the position of the positive electrode spring piece 21 cannot exceed the end of the baffle 13 toward the battery slot 12 .

[0040] The battery generates heat when charging. In order to be able to observe the battery status and quickly dissipate the heat from the battery, preferably, a heat dissipation window is opened relative to the battery to ensure ventilation.

[0041] Because the negative electrode of the battery is relatively flat, the positive electrode spring 21 is protected by the baffle 13, which can prevent the negative electrode of the battery from contacting the positive electrode spring 21 when the battery is placed upside down, thereby preventing mischarging and eliminating the risk of mischarging.

[0042] See also Figure 4 In one embodiment of the present application, the switch structure is a connecting hardware 3, which is connected to one side of the battery slot 12, one end of the connecting hardware 3 is connected to the charging motherboard 11, and the other end is provided with an elastic connecting end 31 facing the flip structure 4; when the locking structure 5 is clamped to the battery compartment 1, the negative pole hardware 22 abuts against the elastic connecting end 31.

[0043] In order to protect the equipment and avoid potential dangers, the charging module 2 needs to be closed after the flip structure 4 is closed before it can work. The connecting hardware 3 can be relatively stably connected to the charging mainboard 11 to avoid damage to the battery compartment 1 when it vibrates violently, causing the equipment to malfunction. Before the flip structure 4 is closed, the farthest end of the elastic connecting end 31 cannot be connected to the negative pole hardware 22, which can play the role of a switch structure very well. When the flip structure 4 is closed, the negative pole hardware 22 and the elastic connecting end 31 can be deformed to form a more stable connection, which can effectively ensure the stable operation of the charging compartment.

[0044] See also Figures 3 and 4 In one embodiment of the present application, a rotating shaft 14 is provided on the inner wall of the battery compartment 1 toward the elastic connection end 31, the negative electrode hardware 22 is rotatably connected to the rotating shaft 14, and the flip cover structure 4 is connected to the end of the negative electrode hardware 22 away from the battery slot 12.

[0045] The negative electrode hardware 22 is directly connected to the rotating shaft 14, so that the negative pole of the charging module 2 can be stably connected to the charging mainboard 11 at the first time. The flip cover structure 4 can be used to compress the negative electrode hardware 22 to make the connection between the two more stable. Such a structure is relatively simple and can further reduce the size of the charger, making the charger easy to carry.

[0046] See also Figures 3 to 6 In one embodiment of the present application, the flip cover structure 4 includes a flip cover 41 and a sliding cover 45: the bottom edge of the flip cover 41 is provided with a mounting groove 42 for mounting the negative electrode hardware 22, and the end of the flip cover 41 facing away from the mounting groove 42 is provided with a buckle 43; the sliding cover 45 is slidably connected to the flip cover 41, and the sliding cover 45 is provided with a limiting slide groove 46 relative to the buckle 43, and the buckle 43 is slidably connected to the limiting slide groove 46, the side wall of the sliding cover 45 is provided with a first hook, and the inner wall of the battery compartment 1 is provided with a second hook, and the first hook and the second hook constitute a locking structure 5; when the sliding cover 45 slides in a direction away from the switch structure, the first hook releases the second hook, thereby realizing the loosening of the flip cover structure 4 relative to the battery compartment 1.

[0047] The flip cover 41 wraps around the negative electrode hardware 22 through the installation groove 42, which can prevent the negative electrode hardware 22 from being electrically connected to the outer wall of the battery compartment 1, avoiding safety hazards. The flip cover 41 and the sliding cover 45 are slidably connected. The design of the buckle 43 and the limiting slide groove 46 can limit the sliding range of the sliding cover 45 to prevent the sliding cover 45 from separating from the flip cover 41. The side of the sliding cover 45 is provided with a first hook, and the interior of the battery compartment 1 is relatively provided with a second hook. The two buckles 43 are locked with each other during the sliding process of the sliding cover 45, which can effectively lock the flip cover structure 4, ensure the stability of battery charging, and make the charger of this application easy to carry.

[0048] See also Figures 4 to 6 In one embodiment of the present application, an elastic arm is provided at the top of the flip cover 41 facing the sliding cover 45, and an arc-shaped convex rib 44 is provided at the end of the elastic arm away from the flip cover 41. At least two arc-shaped grooves 47 are provided on the inner side of the sliding cover 45 along the sliding direction of the sliding cover 45. The distance between the two arc-shaped grooves 47 farthest apart is less than or equal to the length of the limiting slide groove 46, and the arc-shaped convex rib 44 is clamped in one of the arc-shaped grooves 47.

[0049] When the arc-shaped ridge 44 is connected to the arc-shaped groove 47, the elastic arm will push the flip cover 41 away from the sliding cover 45, making the connection between the buckle 43 and the limiting slide groove 46 tighter. The multiple arc-shaped grooves 47 can be used to limit the different states of the sliding cover 45. This structure can help position the sliding cover 45 and prevent it from loosening. This structure can make the flip cover structure 4 easy to use.
