The first lock body 42 can also be called a first lock tongue, a left lock body, or a left lock tongue, and the second lock body 43 can also be called a second lock tongue, a right lock body, or a right lock tongue.

[0037] The first lock body 42 is operated to move in the unlocking direction, the first lock body 42 drives the linkage member 41 to move, and the linkage member 41 drives the second lock body 43 to move in the unlocking direction.

[0038] The infrared observer power supply device provided in the embodiment of the present application includes a battery compartment 1, a battery rack 2, a battery cover 3 and a lock assembly 4. The battery rack 2 is inserted into the battery compartment 1, the battery cover 3 is pressed on the battery rack 2, and the lock assembly 4 is arranged on the battery cover 3, which can lock or unlock the battery cover 3 with the battery compartment 1. Among them, the lock assembly 4 includes a linkage 41, a first lock body 42 and a second lock body 43. The first end of the first lock body 42 is connected to the linkage 41, and the second end can be engaged with the battery compartment 1; the first end of the second lock body 43 is connected to the linkage 41, and the second end can be engaged with the battery compartment 1; in this way, the first lock body 42 is operated to move in the unlocking direction, the first lock body 42 can drive the linkage 41 to move, and the linkage 41 can drive the second lock body 43 to move in the unlocking direction, so that the battery cover 3 and the battery compartment 1 can be unlocked, so as to facilitate the replacement of the battery of the infrared observer power supply device.

[0039] See also Figure 2 As shown, in one embodiment, the battery cover 3 includes a bottom plate 31 and a top cover 32. The bottom plate 31 may also be referred to as a support plate, and the top cover 32 may also be referred to as a top cover or a protective cover. The top cover 32 is disposed above the bottom plate 31 and connected to the bottom plate 31, and a receiving space is formed between the top cover 32 and the bottom plate 31. Exemplarily, the top cover 32 and the bottom plate 31 may be fixedly connected by screws.

[0040] The lock assembly 4 is arranged in the accommodation space, which can reduce the risk of the lock assembly 4 being unlocked due to being touched by mistake. Exemplarily, when the battery cover 3 is locked with the battery compartment 1, the second end 421 of the first lock body can extend out of the accommodation space and engage with the first lock hole 11 on the battery compartment 1, and the second end 431 of the second lock body can extend out of the accommodation space and engage with the second lock hole 12 on the battery compartment 1. The linkage member 41 of the lock assembly 4 can be supported on the bottom plate 31, and a support block 422 is provided at the bottom of the first lock body 42, and the support block 422 is supported on the bottom plate 31. A support rib can be provided on the bottom plate 31 relative to the second lock body 43, and the second lock body 43 is supported on the support rib, which can increase the reliability of the battery cover 3 and the battery compartment 1. Further, a support column is provided on the first lock body 42 and the second lock body 43, and the support column is perpendicular to the unlocking direction to limit the shaking of the first lock body 42 and the second lock body 43 in this direction.

[0041] The top cover 32 is provided with an elongated hole 33, and the first lock body 42 is provided with an operating handle 423, which corresponds to the elongated hole 33; wherein the direction of the long side of the elongated hole 33 is the same as the unlocking direction of the first lock body 42. Exemplarily, when the second end 421 of the first lock body extends out of the accommodation space and is engaged with the first lock hole 11 on the battery compartment 1, there is a gap between the operating handle 423 and the inner wall of the elongated hole 33 close to the first lock hole 11, so as to facilitate the operation of the operating handle 423. Further, the operating handle 423 of the first lock body 42 may protrude from the elongated hole 33. Further, a limiting rib may be provided on the cover plate relative to the first lock body 42 and the second lock body 43, and the first lock body 42 and the second lock body 43 are respectively abutted against the corresponding limiting ribs.

[0042] See also Figure 2 As shown, in one embodiment, the first end of the linkage member 41 has a first wedge surface 411, the first end of the first lock body 42 has a second wedge surface 424, and the second wedge surface 424 abuts against the first wedge surface 411; the second end of the linkage member 41 has a third wedge surface 412, and the first end of the second lock body 43 has a fourth wedge surface 432, and the third wedge surface 412 abuts against the fourth wedge surface 432. In this way, when the first lock body 42 moves in the unlocking direction, the second wedge surface 424 of the first lock body 42 applies a force to the first wedge surface 411 of the linkage member 41, so that the linkage member 41 moves along the second wedge surface 424 of the first lock body 42. The third wedge surface 412 of the linkage member 41 applies a force to the fourth wedge surface 432 of the second lock body 43, so that the second lock body 43 moves along the third wedge surface 412 of the linkage member 41, that is, the linkage member 41 drives the second lock body 43 to move in the unlocking direction.

[0043] In one embodiment, a driving block is provided at the bottom of the first lock body 42 near the linkage member 41, and a second wedge surface 424 is provided on the driving block. A connecting hole is provided on the second lock body 43, and an inner surface of the connecting hole is a fourth wedge surface 432.

[0044] See also Figure 2 As shown, in one embodiment, the linkage member 41 is a plate-shaped structure supported on the upper surface of the bottom plate 31; a stopper 34 is provided on the bottom plate 31, and the second end of the linkage member 41 abuts against the stopper 34. In this way, the second wedge surface 424 of the first lock body 42 applies a force to the first wedge surface 411 of the linkage member 41, and the stopper 34 applies a horizontal reverse force to the linkage member 41, so that the linkage member 41 moves vertically upward under the relative movement of the first wedge surface 411 and the second wedge surface 424, and then drives the second lock body 43 to move in the unlocking direction, that is, the first lock body 42 is operated to move in the unlocking direction, the second wedge surface 424 at the first end of the first lock body 42 pushes the linkage member 41 to move upward, and the third wedge surface 412 at the second end of the linkage member 41 pushes the fourth wedge surface 432 at the second end of the second lock body 43, driving the second lock body 43 to move in the unlocking direction.

[0045] The normal direction of the first wedge-shaped surface 411 is obliquely downward (in an ascending wedge shape), and the normal direction of the second wedge-shaped surface 424 is obliquely upward. In this way, the first lock body 42 moves in the unlocking direction. For example, the first lock body 42 moves to the left, releasing the clamping connection between the first lock body 42 and the battery compartment 1, driving the linkage member 41 to move, and the linkage member 41 drives the second lock body 43 to move in the unlocking direction, releasing the clamping connection between the second lock body 43 and the battery compartment 1, thereby achieving simultaneous unlocking of the second lock body 43 by unlocking the first lock body 42.

[0046] In one embodiment, guide posts (not shown in the figure) are vertically arranged on both sides of the linkage member, so that the linkage member 41 can be easily moved up and down in the vertical direction under the action of the first lock body 42 .

[0047] See also Figure 2As shown, in one embodiment, the second end of the linkage member 41 has a protrusion, and a third wedge surface 412 is formed on a side surface of the protrusion close to the first end of the linkage member 41; the normal direction of the third wedge surface 412 is obliquely upward (in a descending wedge shape); a groove cavity 433 is provided on the second lock body 43, and a fourth wedge surface 432 is formed on a side wall of the groove cavity 433, and the normal direction of the fourth wedge surface 432 is obliquely downward; the top of the protrusion extends into the groove cavity 433, and the third wedge surface 412 abuts against the fourth wedge surface 432. That is, the normal direction of the third wedge surface 412 is obliquely opposite to that of the first wedge surface 411, so that the movement of the first lock body 42 drives the linkage member 41 to move, and the linkage member 41 can drive the second lock body 43 to move in the opposite direction of the first lock body 42. For example, the first lock body 42 moves to the left to release the clamping connection between the first lock body 42 and the battery compartment 1, and the linkage member 41 can drive the second lock body 43 to move to the right to release the clamping connection between the second lock body 43 and the battery compartment 1.

[0048] In one embodiment, the shape of the protrusion at the second end of the linkage 41 is adapted to the shape of the groove 433 of the second lock body 43, so that when the second lock body 43 is unlocked from the battery compartment 1, the protrusion at the second end of the linkage 41 is inserted into the groove 433 of the second lock body 43, which can limit the movement of the second lock body 43 in the unlocking direction.

[0049] See also Figure 2 As shown, in one embodiment, the battery cover 3 also includes a first electrode plate 35, which is arranged below the bottom plate 31; a battery spring 36 is provided on the first electrode plate 35.

Exemplarily, the first electrode plate is a negative electrode plate, and the second electrode plate is a positive electrode plate.

[0050] See also Figure 2 As shown, in one embodiment, the infrared observer power supply device further includes a sealing ring 5, which is located on the step surface at the opening of the battery compartment 1 component, and the bottom plate 31 is pressed on the sealing ring 5, so that the infrared observer power supply device can have a certain waterproof performance, so that it can work normally in an outdoor environment under bad weather. Among them, the shape of the sealing ring 5 is adapted to the shape of the bottom plate 31 of the battery cover 3, and its material can be rubber. The battery compartment 1 may include a battery rack 2 accommodating portion and a battery cover 3 accommodating portion, and the step surface may be an accommodating surface between the battery rack 2 accommodating portion and the battery cover 3 accommodating portion.

In this way, a force is applied to the first lock body 42 to make the first lock body 42 move along the unlocking direction, compress the first resetting elastic member 44, and the first lock body 42 drives the linkage member 41 to move, and the linkage member 41 drives the second lock body 43 to move along the unlocking direction, compressing the second resetting elastic member 45. After the force is stopped from being applied to the first lock body 42, the first resetting elastic member 44 is reset under the action of its stored elastic potential energy, and can drive the first lock body 42 to reset, and the second resetting elastic member 45 is reset under the action of its stored elastic potential energy, and can drive the second lock body 43 to reset, so as to facilitate the disassembly and maintenance of the battery cover 3 and the battery compartment 1.
