The elastic member rebounds to engage the lock lock mechanism with the lock hook locking surface. The present invention not only makes it easier to lock the lock hook with the lock lock mechanism, but also makes the lock hook and the lock lock mechanism more firmly fixed, preventing the lock hook from falling off the lock lock mechanism. The present invention also provides an unlocking mechanism for a camera battery, which is used to unlock the above-mentioned locking structure, and also provides a camera battery using the above-mentioned locking and unlocking mechanism.

Description

Technical Field

[0001] The invention belongs to the field of power supply for film and television equipment, and more particularly relates to a locking and unlocking structure for a camera battery and a battery. Background Art

[0002] At present, large batteries in the field of film and television equipment power supply mainly use two forms of interfaces and locking methods to power the equipment. One is the V-type interface defined by the Japanese camera manufacturer SONY, such as Figure 1 As shown, the V-shaped battery plate 1-1 installed on the device and the V-shaped battery 1-2 providing external power supply. One is the A-type interface defined by Antonbauer, an American camera equipment manufacturer, such as Figure 2 As shown, the A-type battery plate 2-1 installed on the device and the A-type battery 2-2 providing external power. Currently, most large batteries and devices using large batteries in the industry are designed according to these two interface formats or slightly modified. The locking and unlocking methods are also basically designed based on these two formats.

[0003] As the German camera manufacturer ARRI's products continue to gain increasing acceptance within the industry, they have introduced a third interface and a locking and unlocking method, distinct from the previous two. Consequently, manufacturers of large batteries that support these interfaces have also begun developing batteries that accommodate this new interface and locking and unlocking method.

[0004] like Figure 3 As shown in the figure, this is a new interface proposed by ARRI. The interface is located on the battery plate. The battery plate can be installed independently or integrated into the camera and other equipment. When it is necessary to power the camera and other equipment, the battery and the battery plate are adapted and automatically locked, and the power is supplied to the equipment through the power supply interface 3-2. Figure 4 As shown in FIG5 , in order to make the battery and the battery plate compatible, a lock 4-2 needs to be provided on the battery to cooperate with the lock hook 3-1 of the battery plate to perform the locking and unlocking functions.

[0005] Currently, the structure of the supporting battery products on the market is shown in Figure 5. When the battery is inserted, the lock hook guide surface 3-11 and the lock buckle guide surface 4-22 work together to move the button 4-1 downward until the two guide surfaces are relatively disengaged. The button 4-1 then rebounds until the lock hook locking surface 3-12 and the lock buckle locking surface 4-21 contact and lock. To unlock, you need to manually push the button downward until the two locking surfaces disengage, and then remove the battery to complete the unlocking operation.

[0006] The problem with this technical solution is that during the unlocking operation, according to popular operating habits, the thumb applies force on button 4-1, while the other four fingers act on the right side of the battery, forming a grip on the battery. The thumb's force is directed downward, while the other four fingers need to apply force in the direction of battery unlocking. In other words, the force direction of the thumb and the other four fingers is basically in a vertical state, which is very inconvenient during operation. In addition, due to the battery capacity requirements, the battery itself is relatively wide and thick, which makes it even more difficult to operate in actual operation, reducing the customer experience. In addition, if the button is accidentally left unlocked, there is a risk of the battery falling off, causing unstable power supply or even damage due to falling.

[0007] Therefore, it is necessary to propose an effective solution. Summary of the Invention

[0008] 1. Problem to be solved

[0009] In response to the problem in the prior art that the camera battery is inconvenient to unlock when powered, the present invention provides a locking and unlocking structure and a battery for a camera battery. The locking structure in the present invention cooperates with a button, which can effectively solve the problem of inconvenient unlocking operation in the prior art when unlocking using the button.

[0010] 2. Technical solution

[0011] In order to solve the above problems, the technical solution adopted by the present invention is as follows: a locking structure for a camera battery, which is adapted to the lock hook on the battery buckle plate, the lock hook includes a lock hook locking surface and a lock hook guide surface, and the locking structure of the camera battery includes a lock body and an elastic member, one end of the elastic member is connected to the lock body, and the other end is arranged on the inner side wall of the battery, and a lock lock mechanism is provided on the lock body. When the lock lock mechanism conflicts with the lock hook, the elastic member is deformed by force, and the lock lock mechanism uses the lock hook guide surface to slide under the lock hook, and the elastic member rebounds to engage the lock lock mechanism with the lock hook locking surface. This technical solution not only makes it easier for the lock hook to lock with the lock buckle locking mechanism, but also makes the locking surface of the lock hook fit more closely with the lock buckle locking mechanism, preventing the lock buckle locking mechanism from falling off from under the lock hook; and when unlocking the locking structure in this technical solution, only force needs to be applied in the gripping direction to make the lock hook fall off from the lock buckle locking mechanism, and at the same time, the battery can be pulled out by gripping, which is a more ergonomic unlocking operation and can effectively improve the user experience.

[0012] Furthermore, the battery pack further includes a latch stopper mechanism, which is disposed on the side of the latch body and has a first recessed portion disposed on the inner sidewall of the battery. The first recessed portion is used to limit the range of motion of the latch stopper mechanism so that the lock hook does not separate from the latch locking mechanism. This technical solution utilizes the first recessed portion disposed on the inner sidewall of the battery to limit the range of motion of the latch stopper mechanism, allowing the lock hook to more securely engage with the latch locking mechanism, thereby effectively reducing the risk of the battery accidentally falling off the battery plate.

[0013] Furthermore, the elastic member is a torsion spring, and the latch limiting mechanism is provided with a latch shaft. When the guide surface of the lock hook contacts the latch locking mechanism, the latch body rotates about the latch shaft, twisting the torsion spring until the latch locking mechanism slides under the lock hook. The torsion spring then rebounds, causing the latch locking mechanism to engage with the latch locking surface of the lock hook. In this technical solution, the latch shaft is provided on the latch limiting mechanism. Since the latch limiting mechanism has a larger area than the latch body, a longer torque can be applied to rotate the latch body, whether locking or unlocking, making operation more convenient.

[0014] Furthermore, the elastic member is a spring. When the lock hook guide surface conflicts with the lock buckle locking mechanism, the spring is compressed until the lock buckle locking mechanism slides under the lock hook, and then the spring rebounds to engage the lock buckle locking mechanism with the lock hook locking surface.

[0015] Furthermore, the buckle locking mechanism has a buckle guide surface, which is arcuate, and the buckle locking mechanism uses the buckle guide surface to slide over the hook guide surface. The provision of the buckle guide surface allows the hook locking mechanism to more easily contact the buckle, with the buckle guide surface first contacting the hook guide surface. The arcuate design of the buckle guide surface allows the buckle locking mechanism to move more smoothly relative to the hook.

[0016] The present invention also provides a camera battery unlocking structure for unlocking the aforementioned camera battery locking structure. The unlocking structure includes a button. When the button is pressed, one surface of the button abuts against a surface of a latch body, pressing the latch body downward to release the lock hook from the latch locking mechanism. This technical solution makes it very convenient to unlock the battery from the battery plate; simply applying force to the button in the gripping direction causes the lock hook to fall off the latch locking mechanism, while simultaneously gripping and removing the battery. This provides a more ergonomic unlocking operation and effectively improves the user experience.

[0017] Furthermore, the unlocking mechanism includes a button. When the button is pressed, one surface of the button abuts against one surface of the lock stopper, pressing the lock body downward and causing the lock hook to disengage from the lock lock mechanism. Because the lock stopper has a larger area than the lock body, the button abuts against one surface of the lock stopper, providing a larger force-bearing area during unlocking and a better operating experience.

[0018] Furthermore, it also includes a button shaft, which is arranged on the inner wall of the battery, and the button can rotate around the button shaft;

[0019] Alternatively, the battery may further include a key spring, one end of which is connected to the key and the other end of which is disposed on the inner wall of the battery. When the key is pressed, the key may rotate about the key axis or compress the key spring and drive the lock body to move, causing the lock hook to disengage from the lock mechanism.

[0020] Furthermore, the button does not protrude from the surface of the battery in height. The button in this technical solution does not protrude from the surface of the battery in height, which can better protect the button, especially when the battery accidentally falls, it can prevent the button from being impacted.

[0021] The present invention also provides a camera battery, which adopts the above-mentioned camera battery locking structure and also includes an unlocking structure, wherein the unlocking structure includes a button. When the button is pressed, one surface of the button abuts against one surface of a lock body, and the lock body is pressed downward to cause the lock hook to disengage from the lock locking mechanism.

[0022] or,

[0023] The above-mentioned camera battery locking structure also includes an unlocking structure, which includes a button. When the button is pressed, one surface of the button abuts against one surface of the lock limit mechanism, pressing the lock limit mechanism and the lock body downward, causing the lock hook to disengage from the lock mechanism. In this technical solution, one surface of the button can abut against the lock body or a surface of the lock limit mechanism, thereby causing the lock body to move downward and disengage the lock hook from the lock mechanism. Because the lock limit mechanism has a larger area than the lock body, the button abuts against one surface of the lock limit mechanism, resulting in a larger force-bearing surface during unlocking and a better operating experience.

[0024] A camera battery employs the aforementioned locking structure for a camera battery and further includes an unlocking structure comprising a button and a button shaft. The button shaft is disposed on the inner sidewall of the battery. When the button is pressed, the button rotates about the button shaft, causing one surface of the button to abut against a surface of a latch stopper mechanism. The latch stopper mechanism and the latch body are then pressed downward, causing the lock hook to disengage from the latch locking mechanism. In this technical solution, the locking structure employs a torsion spring to lock the lock hook with the latch locking mechanism, while the unlocking structure employs the button shaft to rotate the button. This structurally makes the coordination of the locking and unlocking structures simpler and more reliable.

[0025] A camera battery employs the aforementioned locking structure for a camera battery and further includes an unlocking structure comprising a button and a button spring. One end of the button spring is connected to the button, and the other end is disposed on the inner wall of the battery. When the button is pressed, the button spring is deformed by force, causing one surface of the button to abut against a surface of a latch body. The latch body is then pressed downward, causing the lock hook to disengage from the latch locking mechanism. In this technical solution, the locking structure employs a spring to lock the lock hook with the latch locking mechanism, while the unlocking structure employs a button spring to achieve depression and rebound of the button. This structurally makes the coordination of the locking and unlocking structures simpler and more reliable.

[0026] Furthermore, the lock catch locking mechanism has a lock catch guide surface, which is arc-shaped, and the lock catch locking mechanism uses the lock catch guide surface to slide over the lock hook guide surface. The arc-shaped lock catch guide surface design enables the lock catch locking mechanism to move more smoothly relative to the lock hook.

[0027] 3. Beneficial effects

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] (1) The present invention can very conveniently lock and unlock the battery and the battery plate. In particular, when unlocking, only force is applied in the gripping direction to release the battery plate from the locking mechanism. At the same time, the battery can be pulled out by gripping it tightly. This makes the unlocking operation more ergonomic and can effectively improve the user experience.

[0030] (2) The elastic locking components such as springs and torsion springs and the limit design of the present invention can effectively prevent the battery from falling off the battery plate due to external factors;

[0031] (3) The design of the present invention can more effectively seal the interior of the battery and has a better waterproof effect;

DETAILED DESCRIPTION

[0053] The present invention will be further described below with reference to specific embodiments.

[0054] Example 1

[0055] The present invention provides a locking and unlocking structure for a camera battery and a camera battery, as shown in FIG6(b), wherein the battery is divided into a battery main body A and a battery interface part B. The battery main body A mainly includes a battery cell, a matching circuit board, etc., and the battery interface part B mainly includes a lock body 7-2, a button 7-3, and an electrical performance interface, etc. The battery interface part B has only an electrical performance interface connected to the battery main body A. The states of the battery and the battery plate during use are shown in FIG6(a) and FIG6(b). The battery 6-2 is connected to the power supply interface of a device such as a camera through the battery plate 6-1. The locking and interface parts on the battery plate 6-1 are of standard size and structure defined by ARRI, as shown in FIG6(a). Figure 3 and Figure 4 As shown; the locking and unlocking structure of the supporting battery 6-2 involved in the present invention and its partial enlarged view, as Figure 7 shown.

[0056] like Figure 8 As shown, the present invention includes a lock body 7-2, a button 7-3, and a torsion spring 7-4, wherein the lock body 7-2 is provided with a lock locking mechanism 7-2-1 and a lock limiting mechanism 7-2-4. Specifically, the lock body 7-2 is provided on the side of the lock limiting mechanism 7-2-4, and the lock locking mechanism 7-2-1 is provided on the side of the lock body 7-2, that is, the lock limiting mechanism 7-2-4, the lock body 7-2 and the lock locking mechanism 7-2-1 are provided in sequence, and the lock shaft 7-2-3 is provided on the lock limiting mechanism 7- 2-4. Of course, the lock shaft 7-2-3 can also be set on the lock body 7-2. The advantage of setting it on the lock limiting mechanism 7-2-4 is that when the battery 6-2 and the battery buckle plate 6-1 are unlocked, since the lock limiting mechanism 7-2-4 has a larger area than the lock body 7-2, the lock shaft 7-2-3 is set on the lock limiting mechanism 7-2-4 and can be as close to the button 7-3 as possible in the horizontal direction. When the button 7-3 is pressed hard to rotate the lock body 7-2, the battery can be easily unlocked. A first recessed portion 11-1 is provided on the inner side wall of the battery 6-2. The first recessed portion 11-1 limits the range of motion and angle of the lock limit mechanism 7-2-4 so that the lock hook 3-1 will not separate from the lock locking mechanism 7-2-1. The lock limit mechanism 7-2-4 has a surface in contact with the button 7-3 as a lock force surface 7-2-2. When the button 7-3 is pressed, the force is transmitted from the lock force surface 7-2-2 to the lock body 7-2, thereby causing the lock body 7-2 to rotate; one end of the torsion spring 7-4 is provided on the inner side wall of the battery 6-2, and the other end is connected to the lock body 7-2. When subjected to force, the lock body 7-2 can rotate around the lock shaft 7-2-3 together with the lock limit mechanism 7-2-4. When the matching battery 6-2 is inserted into the battery buckle plate 6-1, as shown in FIG. Figure 10a As shown, the lock hook guide surface 3-11 on the lock hook 3-1 contacts the lock buckle locking mechanism 7-2-1 on the lock buckle body 7-2. As the battery 6-2 and the battery buckle plate 6-1 continue to move relative to each other, the lock hook guide surface 3-11 continuously applies force to the lock buckle locking mechanism 7-2-1, causing the lock buckle body 7-2 to rotate clockwise around the lock buckle shaft 7-2-3, while compressing the torsion spring 7-4. When the lock hook guide surface 3-11 slides over the lock buckle After the locking mechanism 7-2-1 is tightened, the lock body 7-2 rotates counterclockwise around the lock pull 7-2-3 under the action of the rebound force of the torsion spring 7-4. When the lock limit mechanism 7-2-4 presses against the first recessed portion 11-1, the lock body 7-2 stops rotating. At the same time, the lock locking mechanism 7-2-1 contacts the locking surface 3-12 of the lock hook, so that the battery 6-2 and the battery buckle plate 6-1 are in a locked state. The schematic diagram of the locked state is shown in FIG. Figure 10b shown.

[0057] In this embodiment, the circumference of the lock buckle locking mechanism 7-2-1 is designed as an arc surface, that is, the lock buckle locking mechanism 7-2-1 is roughly a cylindrical structure. The lock buckle locking mechanism 7-2-1 of this structure can play the role of guiding and locking at the same time. In specific implementation, it can also be designed in another form, such as Figure 9 As shown, the lock locking mechanism 7-2-1 has a lock guide surface 7-2-5. Figure 9 In the embodiment shown, the latch guide surface 7-2-1 is designed to be arc-shaped, and the latch locking mechanism 7-2-1 utilizes the latch guide surface 7-2-5 to achieve relative movement with the lock hook guide surface 3-11, which can make it easier for the latch locking mechanism 7-2-1 to slide under the lock hook 3-1 and then lock it.

[0058] When it is necessary to remove the battery 6-2 from the battery plate 6-1, Figure 11 As shown, the button 7-3 is in the width direction of the battery 6-2 ( Figure 11 Under the action of an external force (in the direction indicated by the arrow in the middle), the button rotates counterclockwise around the key shaft 7-3-2. Since the button 7-3 has a surface, namely the button force-applying surface 7-3-1, which contacts the lock force-bearing surface 7-2-2 of the lock limit mechanism 7-2-4, the force applied to the button 7-3 is applied to the lock force-bearing surface 7-2-2 through the button force-applying surface 7-3-1, causing the lock body 7-2 and the lock limit mechanism 7-2-4 to rotate clockwise around the lock shaft 7-2-3, while compressing the torsion spring 7-4 until the lock mechanism 7-2-1 disengages from the lock hook locking surface 3-12, allowing the battery to be removed. Unlike the prior art, the present invention can be unlocked by simply holding the battery with one hand, which is simple and reliable.

[0059] The present invention also has improvements in preventing accidental falling caused by external factors, as shown in Figures 10(b) and Figure 11As shown, when the battery 6-2 is inserted into the battery buckle plate 6-1 and is in a locked state, if it is affected by external factors such as vibration, causing the battery 6-2 to tend to fall off the battery buckle plate 6-1, the lock hook locking surface 3-12 will apply a pulling force to the battery lock buckle locking mechanism 7-2-1, so that the lock buckle body 7-2 tends to rotate counterclockwise around the lock buckle shaft 7-2-3. At this time, the lock buckle limiting mechanism 7-2-4 will be restricted by the first recessed portion 11-1, so that the rotation of the lock buckle body 7-2 is restricted, so that the lock buckle locking mechanism 7-2-1 cannot be separated from the battery buckle plate lock hook locking surface 3-12, thereby preventing the battery from accidentally separating from the battery buckle plate. The first recessed portion 11-1 is a recessed portion arranged on the inner side wall of the battery 6-2, and the lock limit mechanism 7-2-4 is sunken into the first recessed portion 11-1. The first recessed portion 11-1 is designed according to the shape of the lock limit mechanism 7-2-4 of the lock body 7-2. It will not affect the rotation of the lock 7-2 when the battery 6-2 is matched with the battery buckle plate 6-1, and the lock body 7-2 is subject to certain restrictions during rotation, thereby preventing the battery 6-2 from falling off the battery buckle plate 6-1.

[0060] like Figure 15 As shown, a recessed portion 15-2 is provided on the side of the battery 6-2 to minimize the gripping width and make it easier to hold. A number of small ridges 15-3 are distributed on the recessed portion 15-2 to increase friction and prevent it from falling. When the operator's finger presses the button 7-3 to the bottom, it may be inconvenient because the thickness of the battery 6-2 is large, resulting in insufficient contact between the finger and the button 7-3. The chamfered corner 15-1 of the button groove can maximize the contact area between the finger and the button 7-3, thereby improving the comfort of operation. In addition, the button 7-3 is provided in another recessed portion on the side of the battery 6-2, so that the button 7-3 does not protrude in height from the surface of the battery 6-2. This design allows the button 7-3 to be more protected in the event that the battery 6-2 falls. Figure 16 shown.

[0061] Example 2

[0062] The other parts of this embodiment are the same as those of embodiment 1, except that: a spring 7-5 is used instead of the torsion spring 7-4 in embodiment 1. Since the force applied to the button 7-3 can be applied to the lock force surface 7-2-2 through the button force surface 7-3-1 and compress the spring 7-5 downward, there is no need for a button shaft 7-3-2 and a lock pull 7-2-3. One end of the spring 7-5 is arranged on the inner wall of the battery 6-2, and the other end is connected to the lock body 7-2. A button shaft 7-3-2 is replaced by a button spring 7-3-3. One end of the button spring 7-3-3 is arranged on the inner wall of the battery, and the other end is connected to the button 7-3.

[0063] like Figure 12 and Figure 13 As shown, when the battery 6-2 is inserted into the battery buckle plate 6-1, the lock hook guide surface 3-11 on the lock hook 3-1 contacts the lock guide surface 7-2-5 on the lock body 7-2 and exerts a force to move the lock body 7-2 downward and compress the spring 7-5. After sliding over the lock hook guide surface 3-11, the lock body 7-2 rebounds upward under the force of the spring 7-5 until the lock limit mechanism 7-2-4 presses against the first recessed portion 11-1. At the same time, the lock locking mechanism 7-2-1 contacts the lock hook locking surface 3-12 to put the battery 6-2 and the battery buckle plate 6-1 in a locked state. The schematic diagram of the locked state is shown in FIG. Figure 13 shown.

[0064] When it is necessary to remove the battery 6-2 from the battery plate 6-1, Figure 14 As shown, press and hold button 7-3 ( Figure 14 Press the key 7-3 to move left (as shown in the direction indicated by the arrow). Figure 14 The button 7-3-1 is pressed in the direction indicated by the middle arrow, and the force is simultaneously transmitted to the latch force surface 7-2-2 through the button force application surface 7-3-1, causing the latch body 7-2 to move downward, while compressing the spring 7-5. When the latch locking mechanism 7-2-1 is disengaged from the lock hook locking surface 3-12, the battery can be removed. In this embodiment, unlike the design of the button 7-3 in Example 1, the button 7-3 is set on the battery 6-2 through a button spring 7-3-3. When the button 7-3 is pressed, the button spring 7-3-3 is compressed, and the force is transmitted to the latch force surface 7-2-2 through the button force application surface 7-3-1, causing the latch body 7-2 to move downward. In a specific implementation, one end of the button spring 7-3-3 is set on the inner wall of the battery 6-2, and the other end is connected to the button 7-3.

[0065] Similarly, when the battery 6-2 is inserted into the battery plate 6-1 and is locked, Figure 13 、 14 As shown, if the battery 6-2 tends to detach from the battery plate 6-1 due to external factors such as vibration, the lock hook locking surface 3-12 will apply a pulling force to the lock latch locking mechanism 7-2-1, so that the lock latch limiting mechanism 7-2-4 is restricted by the first recessed portion 11-1, resulting in limited displacement, so that the lock latch locking mechanism 7-2-1 cannot detach from the lock hook locking surface 3-12, thereby preventing the battery 6-2 from accidentally detaching from the battery plate 6-1.
