When the battery 50 needs to be replaced or charged, the entire battery pack 30 with the battery 50 mounted thereon may be directly replaced, or the battery pack 30 may be removed and charged directly through the interface 31 of the battery pack 30.
In addition, the locking member 40 only needs to be connected to the battery box 30 and can be connected to the base 20 in a snap-fit manner, and the specific structure is not limited herein. For example, in one embodiment, as shown in fig. 3-4, the catch member 40 has opposite first and second ends 41, 42; the first end 41 is hinged to the battery box 30, and the second end 42 is clamped with the base 20. The first end 41 of the locking member 40 may be provided with a hinge hole 45, the battery case 30 is provided with a cylindrical hinge protrusion 310, and the locking member is hinged on the battery case 30 through the hinge hole 45 and the hinge protrusion 310.
In this embodiment, as shown in fig. 3 to 4, the second end 42 of the locking member 40 is provided with an elastic clipping structure 46, and the elastic clipping structure 46 is elastically clipped to the base 20. Specifically, the elastic clamping structure 46 is U-shaped and has a first elastic arm 461 and a second elastic arm 462, the first elastic arm 461 is connected to the locking element 40, and a clamping protrusion 463 is disposed on a surface of the second elastic arm 462 departing from the first elastic arm 461. Base 20 is equipped with the joint portion 241 relative with the tank bottom of mounting groove 21, and lock catch piece 40 is when the joint with base 20, protruding 463 extends of joint portion 241 is close to one side of the tank bottom of mounting groove 21, and then joint portion 241 can restrict protruding 463 of joint is to keeping away from the direction rotation of mounting groove 21.
Of course, the second elastic arm 462 may be provided with a locking hole, the base 20 may be provided with a locking protrusion, and the locking hole and the locking protrusion may be locked to each other by the deformation of the second elastic arm 462. The specific design can be set according to practical situations so as to realize the clamping between the locking fastener 40 and the base 20.
In addition, for convenience of operation, as shown in fig. 3 to 4, the surface of the locking member 40 facing away from the mounting groove 21 may further be provided with a first recess 47 and a second recess 48, the first recess 47 is located on the side of the first resilient arm 461 facing away from the second resilient arm 462, and the second recess 48 is located on the side of the second resilient arm 462 facing away from the first resilient arm 461. In a specific operation, the user's hand can be placed in the first recess 47 and the second recess 48, and the second elastic arm 462 is driven to move towards the first elastic arm 461 to generate an elastic deformation, so that the elastic clamping structure 46 is clamped to the base 20.
In one embodiment, as shown in fig. 3 to 6, the first end 41 is further provided with a first fastening portion 43, the base 20 is further provided with a second fastening portion 22, and the locking member 40 rotates around its hinge axis to have a first position and a second position. When the locking member 40 is in the first position, the battery case 30 can be disengaged from the mounting groove 21. When the locking member 40 is located at the second position, the second end 42 is clamped to the base 20, and the first fastening portion 43 is fastened to the second fastening portion 22 to limit the first fastening portion 43 to be away from the bottom of the mounting groove 21 in a direction perpendicular to the bottom of the mounting groove 21.
It can be understood that, because the first end 41 of the locking member 40 and the battery case 30 are hinged to each other, the locking member 40 may be pushed toward the notch of the mounting groove 21 (or away from the bottom of the mounting groove) during the installation or use of the battery case 30, and the battery case 30 may tilt out of the mounting groove 21. Therefore, by providing the first fastening portion 43 at the first end 41 of the locking element 40 and providing the second fastening portion 22 on the base 20, when the locking element 40 is in the second position (i.e. when the second end 42 of the locking element 40 is fastened to the base 20), the first fastening portion 43 is located at the second fastening portion 22 for fastening, specifically, the first fastening portion 43 has a limiting surface 431, and the limiting surface 431 is located at a side of the second fastening portion 22 close to the bottom of the mounting groove and faces the second fastening portion 22, so that the second fastening portion 22 can limit the first fastening portion 43 away from the bottom of the mounting groove 21 in a direction perpendicular to the bottom of the mounting groove 21. And then make the first end 41 of the locking part 40 fixed relative to the base 20 under the mutual cooperation of the first buckling part 43 and the second buckling part 22, when the battery box 30 exerts an acting force to the locking part 40 in the direction away from the bottom of the mounting groove 21 due to vibration and the like, the first buckling part 43 and the second buckling part 22 can be mutually abutted and overcome the acting force from the battery box 30, so as to avoid the battery box 30 from tilting out of the mounting groove 21, and ensure that the mounting of the battery box 30 is more stable and firm.
The first fastening portion 43 and the second fastening portion 22 can be formed in various ways, for example, the first end 41 of the locking element 40 is provided with a convex pillar, which is the first fastening portion 43. A limiting protrusion 22 is formed on the inner wall surface of the mounting groove 21, the limiting protrusion 22 extends along the width direction of the mounting groove 21, and the limiting protrusion 22 is the second buckling part 22. When the locking element 40 rotates to the second position, the convex column on the first end 41 also moves to the side of the limiting protrusion 22 close to the bottom of the mounting groove 21, and then the second buckling part 22 can limit the first buckling part 43 to move towards the direction far away from the bottom of the mounting groove.
For another example, referring to fig. 3 and 5, in order to facilitate the processing and increase the compactness of the overall structure, the first fastening portion 43 is a limiting groove 43, the second fastening portion 22 is a limiting protrusion 22, and when the locking member 40 is at the second position, the limiting protrusion 22 is clamped in the limiting groove 43. The first end 41 is provided with a limiting groove 43, and the limiting protrusion 22 is of a columnar structure and extends along the width direction of the base 20; when the locking member 40 is at the second position, the limiting protrusion 22 is clamped in the limiting groove 43.
In the present embodiment, the stopper groove 43 is formed on the hinge arm 44 of the locker 40 and penetrates the hinge arm 44 in the width direction of the battery case 30. In addition, the position-limiting groove 43 has a starting end and a terminating end in the extending direction of the position-limiting groove 43, and the starting end penetrates the end of the hinge arm 44 so that the position-limiting protrusion 22 is engaged into the position-limiting groove 43 from the starting end. When the locking member 40 is in the second position, the limiting projection 22 abuts against the terminal end of the limiting groove 43.
In one embodiment, as shown in fig. 3 or 4, the position-limiting groove 43 extends along the rotation direction of the locking element 40, so that the engagement process between the position-limiting protrusion 22 and the position-limiting groove 43 is smoother.
In one embodiment, as shown in fig. 7, the battery case 30 has a first side 32 and a second side 33 opposite to each other, and the first side 32 and the second side 33 are both provided with a hinge protrusion 310 hinged to the locking member 40, i.e. the locking member 40 is hinged to two opposite sides of the battery case 30 at the same time, so as to better limit the battery case 30 in the mounting groove 21. As shown in fig. 5, the mounting groove 21 has a first wall surface 211 facing the first side surface 32 and a second wall surface 212 facing the second side surface 33, and the first wall surface 211 and the second wall surface 212 are mainly used for preventing the battery case 30 from rotating and deflecting in the mounting groove 21 and limiting the mounting angle of the battery case 30. In addition, the first wall surface 211 and the second wall surface 212 are both provided with the limiting protrusions 22; first side 32 with second side 33 is equipped with the groove 34 of stepping down respectively, the groove 34 of stepping down is followed the depth direction of mounting groove 21 extends, and is used for battery case 30 packs into during the mounting groove 21, for spacing arch 22 provides the passageway of stepping down.
The arrangement of the receding groove 34 enables the battery box 30 to be smoothly mounted in the mounting groove 21 on the basis of avoiding rotation or deflection in the mounting groove 21 due to the width of the adaptive mounting groove 21. In particular, the battery case 30 can be mounted in the mounting groove 21 with the relief groove 34 facing the position-limiting protrusion 22 in the mounting groove 21, and then the locking member 40 can be driven to the second position.
In an embodiment, referring to fig. 3 and 7, the locking element 40 further has two opposite hinge arms 44, each hinge arm 44 is provided with the limiting slot 43 and a hinge hole 45 hinged to the hinge protrusion 310; the first side surface 32 and the second side surface 33 are further respectively provided with a limiting boss 35, and when the locking element 40 is located at the second position, the hinge arm 44 is located at one side of the limiting boss 35 departing from the groove bottom of the installation groove 21.
Specifically, retaining boss 35 has a retaining land, which may be planar and facing the slot of mounting slot 21, and hinge arms 44 extend generally along the length of battery compartment 30 and parallel thereto when catch member 40 is in the second position. It can be understood that when the battery case 30 has a tendency to move toward the notch of the mounting groove 21 in a shock state, the position restricting projection 35 abuts against the hinge arm 44 of the locking piece 40. Because the articulated arm 44 is provided with the limit groove 43 clamped with the limit protrusion 22, the articulated arm 44 is not easy to rotate and can apply reverse acting force to the limit boss 35, so that the battery box 30 is firmly pressed in the mounting groove 21, and the battery box 30 is prevented from tilting out of the mounting groove 21.
In one embodiment, as shown in fig. 8, the battery box 30 includes a first box body 38 and a second box body 39, and the first box body 38 and the second box body 39 are connected by screws and jointly enclose a mounting cavity; the battery 50 is compressed within the mounting cavity by the first casing 38 and the second casing 39 together.
Specifically, in this embodiment, the first box body 38 and the second box body 39 are square boxes with open slots, the openings of the first box body 38 and the second box body 39 are opposite and fixedly connected through screws, and the two open slots of the first box body 38 and the second box body 39 enclose a mounting cavity together.
