An embodiment of the present invention provides a battery locking device 100, the battery locking device 100 is used for detachably mounting a battery 400, wherein the battery 400 is disposed in a containing cavity 500 of a housing 10 (not shown). In the present embodiment, the battery includes a storage battery 400, a battery, and other components capable of supplying electric energy. The battery lock device 100 is generally mounted on an electric vehicle such as an electric motorcycle or an electric bicycle.

As shown in fig. 1 to 3 and 12, the battery locking device 100 includes a latch 20, a rotation connection assembly 30, and a position limiting connection assembly 40, wherein a front surface of the latch 20 is formed with a fastening portion 21 capable of being fastened to a battery 400, and a rear surface of the latch 20 is provided with the rotation connection assembly 30 and the position limiting connection assembly 40. Note that the front surface of the clip 20 is a surface of the clip 20 facing the battery 400, and the back surface of the clip 20 is a surface of the clip 20 facing away from the battery 400.

The buckle 20 is rotatably connected to the housing 10 through the rotating connection assembly 30, the end of the limiting connection assembly 40 can extend to the housing 10 to limit the rotation of the buckle 20, so that the buckle portion 21 of the buckle 20 is buckled with the top of the battery 400, and the end of the limiting connection assembly 40 can also be retracted to the buckle 20 to release the connection between the buckle 20 and the battery 400 through the buckle 20.

It can be understood that the buckle 20 can rotate relative to the housing 10, when the battery 400 needs to be fixedly mounted, the user rotates the buckle 20 in a direction close to the battery 400, and after the buckle 20 rotates to the target position, the limit connection assembly 40 extends to the housing 10 to limit the rotation of the buckle 20, so that the buckling part 21 of the buckle 20 is buckled with the top of the battery 400 to limit the movement of the battery 400, i.e. the mounting and fixing of the battery 400 are completed.

When the battery 400 needs to be released from the fixing, the limit connection assembly 40 retracts into the buckle 20, and the buckle 20 rotates in a direction away from the battery 400, so that the connection between the buckle 20 and the battery 400 is released, that is, the fixing of the battery 400 is released.

In summary, compared with the prior art, the battery locking device 100 has at least the following advantages: on one hand, the battery locking device 100 has strong stability for installing and fixing the battery 400 through the battery locking device 100, and can avoid the phenomenon that the battery 400 moves up and down to cause poor contact between the battery 400 and a power supply interface of a vehicle; on the other hand, the battery locking device 100 has a compact overall structure and occupies a small space, so that the private space of a user in the electric motorcycle can be increased to a great extent, and the user can complete the fixed installation of the battery 400 or release the fixation of the battery 400 only by rotating the fastening component, and the operation is simple and convenient.

In order to make the technical solution of the present invention better understood, the technical solution of the embodiment of the present invention will be clearly and completely described below with reference to fig. 1 to 13.

Further, as a specific implementation manner in some embodiments of the present invention, as shown in fig. 2, fig. 3 and fig. 5, in order to improve the compactness of the overall structure of the battery locking device 100 and protect the internal components, the back surface of the buckle 20 is formed with the mounting cavity 22, the limiting connection assembly 40 and the rotating connection assembly 30 are transversely disposed in the mounting cavity 22, and both end portions of the limiting connection assembly 40 and the rotating connection assembly 30 can extend out of the mounting cavity 22.

In addition, the battery locking device 100 further includes a manual opening and closing assembly 50 vertically disposed on the back of the buckle 20, a portion of the manual opening and closing assembly 50 is exposed out of the buckle 20 from the mounting cavity 22, and a portion of the manual opening and closing assembly 50 extends into the mounting cavity 22 and can interact with the limiting connection assembly 40, so that two ends of the limiting connection assembly 40 extend out of the buckle 20 to be connected with the housing 10 or retract to the buckle 20.

Further, as a specific implementation manner in some embodiments of the present invention, as shown in fig. 2, fig. 3, fig. 7 and fig. 8, the limiting connection assembly 40 includes a first elastic component 41 and two limiting components 42, and a middle portion of each of the two limiting components 42 is connected to a portion of the manual opening and closing assembly 50 extending into the installation cavity 22. One end of one limiting member 42 abuts against one end of the first elastic member 41, and the other end is movably inserted into one side of the buckle 20 and can extend out of the mounting cavity 22 to be movably connected with the housing 10; one end of the other limiting member 42 abuts against the other end of the first elastic member 41, and the other end is movably inserted into the other side of the buckle 20 and can extend out of the mounting cavity 22 to be movably connected with the housing 10, so that one end of each limiting member 42 can extend out of the buckle 20 to be connected with the housing 10 or retract to the buckle 20.

It should be noted that, when the position of the retaining member 42 on the buckle 20 needs to be released, a user only needs to use the manual opening and closing assembly 50, and the two retaining members 42 are retracted into the buckle 20 under the action of the manual opening and closing assembly 50, so that the position of the retaining member 42 on the buckle 20 can be released, and then the buckle 20 is rotated to release the fixation of the battery 400.

It should be noted that, when the manual opening and closing assembly 50 is operated, the first elastic element 41 is in a compressed state to generate an elastic force opposite to the acting force, and after the position of the limiting element 42 on the buckle 20 is released, the two limiting elements 42 can be restored to the initial positions under the action of the first elastic element 41, that is, one end of the limiting element 42 extends out of the installation cavity 22. At this time, the first elastic member 41 may not have an elastic force in a natural state.

In an alternative embodiment, the manual opening and closing assembly 50 includes a hand-pulling portion (not shown) and two elastic connection portions (not shown), wherein one end of each elastic connection portion (not shown) is connected to the hand-pulling portion (not shown), and the other end is connected to the corresponding limiting member 42. It can be understood that, when a user manually stretches the pulling portion (not shown), the two elastic connection portions (not shown) can respectively drive the limiting members 42 to move inward, that is, the limiting members 42 retract to the buckle 20, so as to release the position limitation on the buckle 20, and further release the fixing of the battery 400 by the buckle 20.

When the user manually stretches the pulling portion (not shown), the two elastic connecting portions (not shown) are elastically deformed, and the first elastic member 41 is compressed and also elastically deformed.

When the user releases the pulling portion (not shown), the pulling portion (not shown) returns to the original position by the action of the two elastic connecting portions (not shown). Meanwhile, the two limiting members 42 move outwards under the action of the first elastic member 41, that is, the limiting members 42 extend out of the mounting cavity 22 to be movably connected with the housing 10, so as to limit the position of the buckle 20 again.

In another alternative embodiment of this embodiment, as shown in fig. 2, 3 and 6, the manual opening and closing assembly 50 includes a key 51 and a second elastic member 52, the key 51 includes a head 511 and two rigid connecting portions 512, a portion of the head 511 is exposed from the buckle 20, and the bottom of the head 511 is provided with the second elastic member 52 to drive the head 511 to move back and forth along the pressing direction. In addition, one end of each rigid connection portion 512 is connected to the head portion 511, and the other end thereof is movably inserted into the corresponding limiting member 42 along the pressing direction, so that the other end of the corresponding limiting member 42 extends out of the housing 10 or retracts into the buckle 20.

Further, as a specific implementation manner in some embodiments of the present invention, in order to make the limiting member 42 slide more smoothly, as shown in fig. 6 to fig. 8, two rigid connection portions 512 are formed with a guide surface 5121 gradually inclined from the head portion 511 to the limiting member 42, each limiting member 42 is provided with a guide hole 421 capable of matching with the guide surface 5121, and the rigid connection portions 512 are movably inserted into the corresponding guide holes 421. It should be noted that, when the user presses the key 51, the rigid connection portion 512 moves downward, and as the downward distance of the rigid connection portion 512 increases, the limiting member 42 is driven to slide inward, that is, the limiting member 42 retracts into the buckle 20, so that the buckle 20 can rotate in a direction away from the battery 400, and the battery 400 is released from being mounted and fixed.

In this embodiment, as shown in fig. 7 and 8, the guiding hole 421 is a rectangular hole, and the wall of the hole on the side where the guiding hole 421 contacts with the inclined guiding edge is an inclined surface, and the angle of the inclined surface matches with the angle of the guiding surface 5121. Thus, the rigid connection portion 512 can be prevented from being jammed or stuck when sliding along the guide hole 421, and the user experience can be prevented from being affected.

Of course, in other embodiments, the guiding hole 421 may also be in other shapes such as trapezoid, square, etc., which the present invention is not limited to, and those skilled in the art can adjust adaptively.

Further, as a specific implementation manner in some embodiments of the present invention, as shown in fig. 3, fig. 8, fig. 12 and fig. 13, the two sides of the casing 10 are respectively formed with mounting ribs 11, and each mounting rib 11 is provided with a limiting hole 111 for movably inserting the other end of the corresponding limiting member 42. It should be noted that, when the buckle 20 rotates to the target position, one end of the limiting member 42 extends out of the installation cavity 22 and extends into the limiting hole 111, so that the limiting member 42 is movably connected with the housing 10 to limit the movement of the buckle 20.

In addition, as shown in fig. 12, on one side of the mounting rib 11 close to the mounting cavity 22, a clearance groove 112 is further formed on each mounting rib 11, and when the buckle 20 rotates relative to the fixing plate, the other end of the corresponding limiting member 42 is movably inserted into each clearance groove 112, so as to avoid interference in the rotation process of the buckle 20. It should be noted that the shape of the clearance groove 112 matches the shape of the motion track of the position-limiting element 42 during the rotation of the buckle 20.

It can be understood that, during the movement process of the buckle 20 approaching (or departing) the battery 400, one end of the limiting member 42 is in a state of extending out of the installation cavity 22, and one end of the limiting member 42 is inserted into the clearance groove 112 and can slide along the clearance groove 112, so as to avoid the interference generated during the rotation process of the buckle 20 and the abrasion of the components.

Further, as a specific embodiment of the battery locking device 100 provided by the present invention, as shown in fig. 8, fig. 9 and fig. 12, the rotation connection assembly 30 includes a rotation shaft 31 and a third elastic member 32, the rotation shaft 31 is transversely disposed on the buckle 20, and both ends of the rotation shaft respectively extend out of the installation cavity 22 to be rotatably connected with the housing 10, the third elastic member 32 is sleeved on the rotation shaft 31 in the installation cavity 22, so as to drive the buckle 20 to rotate toward the direction departing from the battery 400 automatically relative to the housing 10.

In the present embodiment, as shown in fig. 5, the buckle 20 is provided with a first mounting hole 23, and as shown in fig. 12, the housing 10 is provided with a second mounting hole 113 corresponding to the first mounting hole 23. Specifically, when the hinge 31 is installed, the hinge 31 passes through the second mounting hole 113, the first mounting hole 23 and the third elastic member 32 in sequence from the outside of the housing 10, and two ends of the hinge 31 respectively extend out of the mounting cavity 22 to be rotatably connected with the housing 10. In addition, an E-shaped circlip (not shown) is further disposed on both sides of the rotating shaft 31 for limiting the movement of the rotating shaft 31, so as to prevent the position of the rotating shaft 31 from shifting when the buckle 20 rotates around the rotating shaft 31, which affects the fixing of the buckle 20 to the battery 400.

It should be noted that, when it is needed to mount and fix the battery 400, the buckle 20 uses the axis of the rotating shaft 31 as a rotation center, and the user rotates the buckle 20 toward a direction close to the battery 400, so that the buckle 20 abuts against the top of the battery 400, thereby limiting the movement of the battery 400, i.e. completing the mounting and fixing of the battery 400.

It should be noted that, after the battery 400 is mounted and fixed, the third elastic member 32 is elastically deformed to generate an elastic force. When the battery 400 needs to be released from the fixing, the clip 20 automatically rotates in a direction away from the battery 400 with the axis of the rotating shaft 31 as a rotation center by the third elastic member 32, so that the battery 400 is released from the fixing of the clip 20.

Of course, in other embodiments, other suitable structures may be adopted to be rotatably disposed on the housing 10, which is not limited by the present invention and can be adaptively adjusted by those skilled in the art.

Further, as a specific embodiment of the battery locking device 100 provided by the present invention, as shown in fig. 2, fig. 5, fig. 7 and fig. 8, the buckle 20 is provided with a mounting seat 221 in the mounting cavity 22 in a protruding manner, the mounting seat 221 is transversely provided with a mounting groove (not shown) and a sliding channel (not shown), the mounting groove (not shown) is transversely provided with a first elastic member 41 therein, and the sliding channel (not shown) is transversely provided with a limiting member 42 therein; and a first limit structure (not shown) is disposed at the bottom of the mounting seat 221, and the first limit structure (not shown) abuts against a portion of the third elastic element 32. In addition, a second limiting structure (not shown) is disposed on the top of the mounting seat 221, wherein the second elastic member 52 of the manual opening and closing assembly 50 is disposed between the head 511 and the second limiting structure (not shown).

It is understood that when the button 51 is acted upon by a force, the button 51 moves downward, so that the second elastic member 52 is compressed to generate an elastic force; when the acting force on the button 51 is released, the button 51 is restored to the initial position under the action of the second elastic member 52, which is convenient for the user to use next time.

It should be noted that, when the key 51 is not pressed, the key 51 is in a pre-pressed state of the second elastic member 52, the limiting member 42 is in a pre-pressed state of the first elastic member 41, and the limiting member 42 extends out to enter the limiting hole 111 of the housing 10; at this time, the third elastic member 32 is in an operating state, and the generated torsion rotates the latch 20 in a direction away from the battery 400, but the position of the latch 20 can be limited by the limiting member 42 engaging with the limiting hole 111, so that the latch 20 does not rotate around the rotating shaft 31 in a direction away from the battery 400.

In addition, when the key 51 is in a pressed state, the key 51 moves downward to be in a pressed state of the second elastic member 52, the guide holes 421 of the two limiting members 42 contact the rigid connection portion 512, and as the key 51 moves downward, the rigid connection portion 512 presses the hole walls of the guide holes 421 to enable the limiting members 42 to slide inward along the sliding channel (not shown) (specifically, the two limiting members 42 approach to the center), and when the key 51 touches the second limiting structure (not shown) to stop moving, the limiting members 42 contract into the buckle 20 to release the matching between the limiting members 42 and the limiting holes 111. At this time, the stopper 42 is in a pressed state of the first elastic member 41, and the torsion generated by the third elastic member 32 rotates the latch 20 in a direction away from the battery 400, thereby releasing the fixation of the battery 400.

In addition, when the key 51 is pressed downward without an acting force, the key 51 is pressed upward by the elastic force of the second elastic member 52, and the two position-limiting members 42 are not pressed by the rigid connection portion 512 and are then moved outward by the elastic force of the first elastic member 41 (not shown in the figure) along the sliding channel (specifically, the two position-limiting members 42 are moved away from the center), so that the position-limiting members 42 are moved into the position-limiting holes 111 again, and the position-limiting members 42 are engaged with the position-limiting holes 111, thereby limiting the position of the buckle 20.

Based on above-mentioned battery locking device 100, as shown in fig. 9 and fig. 10, the embodiment of the present invention further provides an electric vehicle, wherein the electric vehicle includes a seat barrel 200, a cover plate 300, a battery 400 and the above-mentioned battery locking device 100, the cover plate 300 covers the seat barrel 200 to form the casing 10 of the battery locking device 100 with the accommodating cavity 500, protect the battery 400 from external damage, and prolong the service life of the battery 400.
