[0002] As battery-powered electrical devices become increasingly diverse, the market demand for chargers that are easy to take and put away batteries is also growing. In order to solve the portable charging of batteries, the prior art proposes a portable charging device that provides a charging interface, a power cord, and a container for accommodating / installing batteries. Among them, the containers for accommodating / installing batteries are currently common: a battery holder and a battery compartment similar to a storage box. Among them, when charging a battery holder charger, the battery is inserted into the battery holder, and the battery holder is connected to a power source to charge the battery. In this way, the battery is easy to loosen or fall off during the charging process, resulting in charging interruption and short circuit of the metal contacts of the battery. The charger using a battery compartment similar to a storage box usually forms a accommodating cavity inside through a box body and a box cover to accommodate the battery. The box cover can be opened and closed to open or close the accommodating cavity, which is convenient for taking and putting the battery, and can effectively prevent the battery from loosening or falling during the charging process. However, for some batteries that are used frequently, the storage box needs to be opened and closed frequently. Some storage boxes use a press-lock method to lock the lid, and the lid can be unlocked by pressing the lock. However, during actual use, the lock often gets stuck or loose, making it difficult to reset, which affects the closing and locking of the lid again. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides a charger with convenient battery access. Figures 1 to 4 ,include:

[0025] The box body includes a battery compartment 10, and the battery compartment 10 is provided with a receiving cavity 13 for receiving a battery 20; the battery compartment 10 is a through U-shaped compartment; an automatically reset elastic lock buckle 12 is provided on the first side wall of the receiving cavity 13, and the elastic lock buckle 12 has two states of withdrawing from the lock hole of the battery 20 and extending into the lock hole of the battery 20; at least one positioning member for positioning the battery 20 is provided on the second side wall of the U-shaped compartment; the second side wall is arranged opposite to the first side wall;

[0026] A plurality of charging contacts 131 for electrically connecting to the positive and negative electrodes of the battery 20 ; the charging contacts 131 are disposed in the accommodating cavity 13 .

[0027] In the present invention, the battery compartment 10 is a through U-shaped compartment, which should be understood as follows: the U-shaped compartment includes a bottom surface and two opposite side surfaces, and the other two opposite side surfaces are not provided with side walls, so that batteries 20 of different widths can be accommodated in the U-shaped compartment.

[0028] The two states of the elastic lock buckle 12 are an unlocked state and a locked state, namely: when the elastic lock buckle 12 is in the unlocked state, the elastic lock buckle 12 withdraws from the lock hole of the battery 20, and the battery 20 can be easily put into / taken out of the battery compartment 10; when the elastic lock buckle 12 is in the locked state, the elastic lock buckle 12 extends into the lock hole of the battery 20, and the battery 20 cannot be easily put into / taken out of the battery compartment 10. The elastic lock buckle 12 realizes the change between the unlocked state and the locked state by the elasticity of the elastic lock buckle 12 or the deformation of the deformable elastic member provided in the elastic lock buckle 12.

[0029] It should be noted that, see Figure 6 The charger used in the utility model is suitable for a battery 20 with a positioning block on one side of the surface of the battery 20, and the positioning block matches the positioning member in number and structure. That is, when the positioning block is two positioning protrusions 22, the positioning member also corresponds to two positioning grooves 11; when the positioning block is two positioning grooves 11, the positioning member corresponds to two positioning protrusions 22. Preferably, the positioning block is a positioning protrusion 22, and the positioning member is a positioning groove 11.

[0030] In some embodiments, a lock slot for accommodating the elastic lock 12 is provided on one side wall of the accommodating cavity 13, and the elastic lock 12 includes a mounting plate 121, a lock tongue 122 and an elastic member, one end of the elastic member is connected to the mounting plate 121, and the other end is connected to the side wall of the lock slot, and the lock tongue 122 is provided on a side of the mounting plate 121 away from the elastic member; when the elastic member is compressed until the lock tongue 122 withdraws from the accommodating cavity 13, it is in an unlocked state, and when the elastic member is not subjected to external force, the lock tongue 122 extends into the accommodating cavity 13, it is in a locked state. Figure 5 When the battery 20 is placed in the accommodating cavity 13, the elastic member extends into the accommodating cavity 13 to press the battery 20 or extends into the locking groove 21 correspondingly arranged on the battery 20 to clamp the battery 20 so that the battery 20 is fixed in the accommodating cavity 13; when the battery 20 is placed in or needs to be taken out, the elastic member is pressed and withdraws from the accommodating cavity 13, so that the battery 20 can be easily placed in or taken out of the accommodating cavity 13.

[0031] The positioning groove 11 can be used to align the battery 20 when the battery 20 is installed, and can cooperate with the locking tongue 122 to lock the battery 20 to prevent the battery 20 from detaching from the battery compartment 10 when it is shaken or dropped during charging.

[0032] The elastic member may be a common elastic member, such as a spring or a spring sheet.

[0033] The locking tongue 122 may be made of a rubber elastic material, which may be deformed under pressure and reset when the external force is removed, so that it can not only be used to compress the battery 20 but also prevent the locking tongue 122 from damaging the battery 20 .

[0034] In some embodiments, the mounting plate 121 is an L-shaped plate including a first section 1211 and a second section 1212, and the locking tongue 122 is disposed in the first section 1211; the second section 1212 is provided with a pull head 123 perpendicular to the second section 1212. The pull head 123 is located on the surface of the battery compartment 10, so as to facilitate manually pushing the first section 1211 of the mounting plate 121 away from the accommodating cavity 13, so as to realize that the locking tongue 122 withdraws from the accommodating cavity 13 and unlocks the locked state of the battery 20.

[0035] In some embodiments, the connection between the first section 1211 and the second section 1212 is smoothly transitioned; and / or

[0036] The side wall of the locking groove provided in the accommodating cavity 13 is smoothly transitioned with the surface of the battery compartment 10 , so as to facilitate the sliding of the mounting plate 121 and also facilitate the taking out and putting in of the battery 20 .

[0037] In some embodiments, the battery compartment 10 is further provided with a clearance groove 133 connected to the accommodating cavity 13; the clearance groove 133 is arranged on the side wall of the accommodating cavity 13 where the elastic lock buckle 12 is arranged, and is used to manually buckle the battery 20 when it is in the unlocked state, making it easy to take and put the battery 20.

[0038] In other embodiments, an elastic buffer block made of elastic material and not higher than the charging contact 131 is further provided on the bottom surface of the accommodating cavity 13. The size of the elastic buffer block is smaller than the bottom surface area of ​​the accommodating cavity 13, so that there is a certain gap between the battery 20 and the bottom surface of the accommodating cavity 13, which can not only provide expansion space for the charging of the battery 20, especially the volume change of the lithium-ion battery 20 during the charging process, but also have a heat dissipation effect; furthermore, the elastic buffer block can also push the battery 20 upward by a certain space after the elastic lock 12 is unlocked, which is more conducive to taking and placing the battery 20.

[0039] In some embodiments, a charging port 14 is provided on one side of the battery compartment 10 , and the charging port 14 is a waterproof plug provided in a sunken manner.

[0040] In some embodiments, the waterproof plug is provided with a waterproof cap.

[0041] In some embodiments, a display screen 15 is further provided on the surface of the charger for convenient battery access, and the display screen 15 is electrically connected to the charging interface 14 and the charging contacts 131 .

[0042] In some embodiments, see Figure 6 The charging contact 131 is located on the bottom surface of the U-shaped compartment, so that when the battery 20 is pressed and fixed in the battery compartment 10, the metal electrode 23 on the battery 20 is also pressed to contact with the charging contact 131 and maintain its contact state, thereby avoiding unsuccessful or intermittent charging due to loose contact between the battery 20 and the charging contact 131.

[0043] It should be noted that, at this time, the metal electrode 23 of the battery 20 used for charging also needs to be arranged at a corresponding position on the corresponding side surface.

[0044] In some embodiments, the charging interface 14 is a waterproof plug that is sunken and provided with a waterproof cap. When the charging interface 14 is not in use, the dust cap is covered to protect the interface and extend its service life. The charging interface 14 is also provided with an insertion direction mark to avoid damage to the charger due to incorrect insertion.

[0045] In some embodiments, a display screen 15 is also provided on the surface of the battery 20 charger, and the display screen 15 is electrically connected to the charging interface 14 and the charging contacts 131, and is used to display the charge level of the battery 20 and indicate whether the charging is successful or not, so as to facilitate user observation.

[0046] In some embodiments, a storage groove 132 for storing the battery 20 wire is also provided on the bottom surface of the U-shaped compartment, so as to facilitate the storage of the wires attached to the battery 20.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
