The battery interface part B is only connected with the electrical interface and the battery body A, the states of the battery and the battery buckle plate are shown in fig. 6(a) and 6(B) when in use, the battery 6-2 is matched and connected with the power supply interface of equipment such as a camera and the like through the battery buckle plate 6-1, and the locking and interface part on the battery buckle plate 6-1 has the standard size and structure defined by ARRI, as shown in fig. 3 and 4; the locking and unlocking structure of the battery 6-2 according to the present invention and a partial enlarged view thereof are shown in fig. 7.

As shown in FIG. 8, the invention comprises a lock catch body 7-2, a key 7-3 and a torsion spring 7-4, wherein the lock catch body 7-2 is provided with a lock catch locking mechanism 7-2-1 and a lock catch limiting mechanism 7-2-4, specifically, the lock catch body 7-2 is arranged at the side of the lock catch limiting mechanism 7-2-4, the lock catch locking mechanism 7-2-1 is arranged at the side of the lock catch body 7-2, namely, the lock catch limiting mechanism 7-2-4, the lock catch body 7-2 and the lock catch locking mechanism 7-2-1 are arranged in sequence, the lock catch rotating shaft 7-2-3 is arranged on the lock catch limiting mechanism 7-2-4, of course, the lock catch rotating shaft 7-2-3 can also be arranged on the lock catch body 7-2, the lock catch limiting mechanism 7-2-4 has the advantages that when the battery 6-2 and the battery buckle plate 6-1 are unlocked, the lock catch limiting mechanism 7-2-4 is larger in area compared with the lock catch body 7-2, the lock catch rotating shaft 7-2-3 is arranged on the lock catch limiting mechanism 7-2-4 and can be close to the key 7-3 in the horizontal direction as much as possible, and the battery can be unlocked easily when the key 7-3 is pressed to enable the lock catch body 7-2 to rotate. The inner side wall of the battery 6-2 is provided with a first concave part 11-1, the first concave part 11-1 limits the movement range and angle of the lock catch limiting mechanism 7-2-4, so that the lock hook 3-1 cannot be separated from the lock catch locking mechanism 7-2-1, a surface, which is in contact with the key 7-3, of the lock catch limiting mechanism 7-2-4 is a lock catch stress surface 7-2-2, and when the key 7-3 is pressed down, the stress force is transmitted to the lock catch body 7-2 from the lock catch stress surface 7-2-2, so that the lock catch body 7-2 rotates; one end of the torsion spring 7-4 is arranged on the inner side wall of the battery 6-2, the other end is connected with the lock catch body 7-2, the lock catch body 7-2 can rotate around the lock catch rotating shaft 7-2-3 together with the lock catch limiting mechanism 7-2-4 when stressed, when the matched battery 6-2 is inserted into the battery buckle plate 6-1, as shown in figure 10a, a lock hook guide surface 3-11 on the lock hook 3-1 is contacted with a lock catch locking mechanism 7-2-1 on the lock catch body 7-2, along with the continuous relative movement of the battery 6-2 and the battery buckle plate 6-1, the lock hook guide surface 3-11 continuously applies acting force to the lock catch locking mechanism 7-2-1 to enable the lock catch body 7-2 to rotate around the lock catch rotating shaft 7-2-3 along the clockwise direction, simultaneously compressing the torsion spring 7-4; after the lock hook guide surface 3-11 slides over the lock hook locking mechanism 7-2-1, the lock hook body 7-2 rotates around the lock hook rotary pump 7-2-3 along the counterclockwise direction under the action of the resilience force of the torsion spring 7-4, when the lock hook limiting mechanism 7-2-4 abuts against the first concave part 11-1, the lock hook body 7-2 stops rotating, meanwhile, the lock hook locking mechanism 7-2-1 contacts with the lock hook locking surface 3-12 to enable the battery 6-2 and the battery buckle plate 6-1 to be in a locking state, and the locked state schematic diagram is shown in fig. 10 b.

In this embodiment, the latch locking mechanism 7-2-1 is designed to have an arc-shaped circumference, that is, the latch locking mechanism 7-2-1 is substantially a cylindrical structure, and the latch locking mechanism 7-2-1 of this structure can simultaneously perform guiding and locking functions, and in a specific implementation, can be designed to have another form, as shown in fig. 9, the latch locking mechanism 7-2-1 has a latch guiding surface 7-2-5, in the embodiment shown in fig. 9, the latch guiding surface 7-2-1 is designed to be arc-shaped, and the latch locking mechanism 7-2-1 utilizes the latch guiding surface 7-2-5 to realize a relative movement with the latch hook guiding surface 3-11, so that the latch locking mechanism 7-2-1 can be more easily slid into the lower portion of the latch hook 3-1, and then locking is performed.

When the battery 6-2 needs to be taken down from the battery buckle 6-1, as shown in fig. 11, the key 7-3 rotates anticlockwise around the key rotating shaft 7-3-2 under the action of the external force in the width direction (the direction indicated by the arrow in fig. 11) of the battery 6-2, because the key 7-3 has one surface, namely the key force applying surface 7-3-1, which is abutted against the lock catch force receiving surface 7-2-2 on the lock catch limiting mechanism 7-2-4, the acting force applied on the key 7-3 is applied to the lock catch force receiving surface 7-2-2 through the key force applying surface 7-3-1, so that the lock catch body 7-2 and the lock catch limiting mechanism 7-2-4 rotate clockwise around the lock catch rotating shaft 7-2-3 together, and meanwhile, the torsion spring 7-4 is compressed until the latch locking mechanism 7-2-1 is separated from the locking surface 3-12 of the latch hook, and then the battery can be pulled out. Different from the prior art, the unlocking device can be operated by holding the battery with one hand, and is simple and reliable.

The invention also has improvement in the aspect of preventing accidental falling caused by external factors, as shown in fig. 10(b) and fig. 11, when a battery 6-2 is inserted into a battery buckle plate 6-1 and is in a locking state, if the battery 6-2 tends to fall off from the battery buckle plate 6-1 due to the external factors such as vibration and the like, a tensile force is applied to the battery lock catch locking mechanism 7-2-1 by a lock catch locking surface 3-12, so that the lock catch body 7-2 has a tendency to rotate anticlockwise around a lock catch rotating shaft 7-2-3, at the moment, the lock catch limiting mechanism 7-2-4 is limited by a first concave part 11-1, the rotation of the lock catch body 7-2 is limited, and the lock catch locking mechanism 7-2-1 cannot be separated from the lock catch locking surface 3-12 of the battery buckle plate, the battery buckle plate has the function of preventing the battery from being accidentally separated from the battery buckle plate. The first concave part 11-1 is a concave part arranged on the inner side wall of the battery 6-2, the lock catch limiting mechanism 7-2-4 is sunk into the first concave part 11-1, the first concave part 11-1 is designed according to the shape of the lock catch limiting mechanism 7-2-4 of the lock catch body 7-2, the rotation of the lock catch 7-2 when the battery 6-2 is matched with the battery buckle plate 6-1 cannot be influenced, the lock catch body 7-2 is limited to a certain extent when rotating, and therefore the battery 6-2 is prevented from falling off from the battery buckle plate 6-1.

As shown in FIG. 15, the battery 6-2 has a concave portion 15-2 on the side to reduce the holding width as much as possible for easier holding, and a plurality of small convex strips 15-3 are distributed on the concave portion 15-2 to increase the friction force and prevent falling. When the operator presses the button 7-3 to the bottom with the finger, the inconvenience may be caused by the insufficient contact surface between the finger and the button 7-3 due to the large thickness of the battery 6-2, and the operation comfort is improved by increasing the contact surface between the finger and the button 7-3 as much as possible by the button groove chamfer 15-1. In addition, the key 7-3 is disposed in another recess portion of the side of the battery 6-2 such that the key 7-3 does not protrude in height from the surface of the battery 6-2, which is a design such that the key 7-3 is more protected in the case where the battery 6-2 is dropped, as shown in fig. 16.

The other parts of this embodiment are the same as those of embodiment 1, except that: the spring 7-5 is used for replacing the torsion spring 7-4 in the embodiment 1, and because the acting force applied on the key 7-3 can be applied on the lock catch stress surface 7-2-2 through the key force application surface 7-3-1 and the spring 7-5 is compressed downwards, the key rotating shaft 7-3-2 and the lock catch rotating rod 7-2-3 are not needed, one end of the spring 7-5 is arranged on the inner side wall of the battery 6-2, and the other end is connected with the lock catch body 7-2; the key rotating shaft 7-3-2 is replaced by a key spring 7-3-3, one end of the key spring 7-3-3 is arranged on the inner side wall of the battery, and the other end is connected with the key 7-3.

As shown in fig. 12 and 13, when the battery 6-2 is inserted into the battery buckle plate 6-1, the latch hook guide surface 3-11 on the latch hook 3-1 contacts with the latch hook guide surface 7-2-5 on the latch body 7-2 to apply an acting force, so that the latch body 7-2 moves downward, and the spring 7-5 is compressed, after sliding over the latch hook guide surface 3-11, the latch body 7-2 rebounds upward under the acting force of the spring 7-5 until the latch stopper 7-2-4 abuts against the first recess 11-1, and the latch locking mechanism 7-2-1 contacts with the latch hook locking surface 3-12 to lock the battery 6-2 and the battery buckle plate 6-1, and the locked state is schematically shown in fig. 13.

When the battery 6-2 needs to be taken down from the battery buckle 6-1, as shown in fig. 14, the button 7-3 is pressed (the direction indicated by the arrow in fig. 14 is forced), the button 7-3 moves leftwards (the direction indicated by the arrow in fig. 14), meanwhile, the force is transmitted to the lock catch force bearing surface 7-2-2 through the button force bearing surface 7-3-1, so that the lock catch body 7-2 moves downwards, the spring 7-5 is compressed, and the battery can be pulled out when the lock catch locking mechanism 7-2-1 is separated from the lock catch locking surface 3-12. In the embodiment, different from the design of the key 7-3 in the embodiment 1, the key 7-3 is arranged on the battery 6-2 through a key spring 7-3-3, when the key 7-3 is pressed down, the key spring 7-3-3 is compressed, the acting force is transmitted to the lock catch stress surface 7-2-2 through the key force application surface 7-3-1, and the lock catch body 7-2 moves downwards; when the battery is concretely implemented, one end of the key spring 7-3-3 is arranged on the inner side wall of the battery 6-2, and the other end is connected with the key 7-3.

Similarly, when the battery 6-2 is inserted into the battery buckle plate 6-1 and is in a locked state, as shown in fig. 13 and 14, if the battery 6-2 tends to be disengaged from the battery buckle plate 6-1 due to external factors such as vibration and the like, the locking surface 3-12 of the locking hook can apply a pulling force to the locking mechanism 7-2-1 of the locking hook, so that the locking limiting mechanism 7-2-4 of the locking hook is limited by the first concave part 11-1, and displacement is limited, so that the locking mechanism 7-2-1 of the locking hook cannot be disengaged from the locking surface 3-12 of the locking hook, and the effect of preventing the battery 6-2 from being accidentally disengaged from the battery buckle plate 6-1 is achieved.
