Description

Technical Field

[0001] This application relates to the field of battery pack technology, and in particular to a battery cover, a battery pack, and an infrared sight. Background Technology

[0002] An infrared sight is a device that uses infrared technology for aiming, primarily used to provide accurate aiming capabilities at night or in low-light environments. Currently, most infrared sights use standard battery types, such as 18650, 18700, and CR123A batteries, which offer advantages such as portability and versatility; however, the limited capacity of a single battery results in insufficient battery life. Therefore, some sights utilize removable battery packs for power supply.

[0003] The detachable battery pack structure of existing sight products usually does not have a self-locking function, which can easily lead to accidental contact by the user, causing the battery pack to pop up, the device to lose power, and affecting the user experience.

[0004] Therefore, in view of the above-mentioned technical problems, how to provide a detachable structure with a self-locking function is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] It should be noted that in this embodiment, the orientation or positional relationship indicated by terms such as "upper," "lower," "front," and "rear" is based on the orientation or positional relationship shown in the accompanying drawings. It is used only for the convenience of describing this application and for simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application. Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0050] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0051] like Figure 1 As shown, in this embodiment, a battery cover 10 is provided. The battery cover 10 includes a cover body 1, a pressing part 2, a toggle part 3, and a locking part 4. The cover body 1 is disposed on the opening side of the battery compartment 40, and the pressing part 2 is disposed on the cover body 1. The pressing part 2 can be movably disposed relative to the cover body 1 along the pressing direction. That is, when the pressing part 2 is pressed, the pressing part 2 can move along the pressing direction. When it is released, the pressing part 2 can also reset in the opposite direction to the pressing direction.

[0052] The actuating part 3 is movably mounted on the pressing part 2 and is fixed relative to the pressing part 2 in the aforementioned pressing direction. That is, the actuating part 3 and the pressing part 2 move synchronously in the pressing direction. When the pressing part 2 moves in the pressing direction or in the opposite direction, the actuating part 3 can move synchronously accordingly. Furthermore, the actuating part 3 can also move relative to the pressing part 2. When the actuating part 3 moves to the first position on the pressing part 2, the actuating part 3 can be fixed relative to the cover 1 in the pressing direction. Thus, with the actuating part 3 and the pressing part 2 fixed relative to each other in the pressing direction, the pressing part 2 is also fixed relative to the cover 1 in the pressing direction, making it impossible to press the pressing part 2. When the actuating part 3 moves to the second position on the pressing part 2, the actuating part 3 moves relative to the cover 1 in the pressing direction, causing the pressing part 2 to also move relative to the cover 1, allowing the pressing part 2 to be pressed.

[0053] The locking part 4 is used to lock relative to the battery compartment 40. When the locking part 4 is in the locked position, it locks relative to the battery compartment 40, preventing the battery cover 10 from being opened. When the locking part 4 is in the unlocked position, it unlocks relative to the battery compartment 40, allowing the battery cover 10 to be opened quickly. The locking part 4 is connected to the pressing part 2, and it can switch between the locked and unlocked positions depending on the position of the pressing part 2. Thus, the movement of the pressing part 2 controls the relative locking and unlocking of the battery cover 10 and the battery compartment 40.

[0054] It should be noted that the relative locking of the locking part 4 and the battery compartment 40 means that the locking part 4 can be directly locked to the battery compartment 40, or the locking part 4 can be locked to the device body 30 that fixes the battery compartment 40, so as to ensure that the battery cover 10 is fixed relative to the battery compartment 40 and cannot be opened in the locked state, both of which fall within the protection scope of this application.

[0055] Furthermore, there are various ways to connect the locking part 4 and the pressing part 2, such as rotational connection, sliding connection, contact connection, etc. These will not be described in detail here. The key is to ensure that the locking part 4 can make corresponding movements according to the movement of the pressing part 2. Of course, the locking part 4 should remain in the locked position when the pressing part 2 is not pressed to ensure the locking effect of the locking part 4. After the pressing part 2 is pressed, the locking part 4 can gradually move to the unlocked position, thereby realizing the relative locking and unlocking of the battery cover 10 and the battery compartment 40.

[0056] In summary, when the toggle part 3 is in the first position, it is fixed relative to the cover 1 in the pressing direction, the pressing part 2 cannot be pressed down, and the locking part 4 is locked relative to the battery compartment 40 in the locking position. The battery cover 10 is in a self-locking state to prevent the user from accidentally touching it and causing the device to lose power during use. When the toggle part 3 is in the second position, it moves relative to the cover 1 in the pressing direction. At this time, the pressing part 2 can be pressed down. After the pressing part 2 is pressed down, the locking part 4 will move to the unlocking position, thereby unlocking the battery cover 10 and the battery compartment 40, so that the user can remove and replace the battery.

[0057] Please refer to Figure 2 The cover 1 includes an upper cover 11 with a pressing hole 111 and a lower cover 12 fixedly connected to the upper cover 11. The upper cover 11 and the lower cover 12 are fixedly connected to form the housing structure of the battery cover 10. The pressing part 2 includes a pressing button 21 disposed in the pressing hole 111. The pressing button 21 can move between the upper cover 11 and the lower cover 12. A toggle groove 23 is provided on the pressing button 21. The two side walls opposite to the toggle groove 23 are provided with sliding grooves 26.

[0058] The actuating part 3 includes an actuating plate 32 with its side extending into the slide groove 26 and an actuating key 31 fixedly connected to the actuating plate 32. The actuating key 31 is located in the actuating groove 23 and is exposed relative to the pressing part 2 for easy manual actuation. The actuating key 31 can drive the actuating plate 32 to move along the slide groove 26, thereby switching the actuating part 3 between a first position and a second position. It should be noted that the above description indicates that the actuating part 3 and the pressing part 2 are relatively fixed in the pressing direction. This function can be achieved by the cooperation of the slide groove 26 and the actuating plate 32. That is, without affecting the normal sliding of the actuating part 3 along the slide groove 26, the side of the actuating plate 32 is engaged with the slide groove 26 in the pressing direction, thereby achieving relative fixation of the actuating part 3 and the pressing part 2 in the pressing direction.

[0059] In one embodiment, both the toggle plate 32 and the toggle key 31 have a limiting hole 33 opening towards the lower cover 12 at least in the former. Please refer to [reference needed]. Figure 2 and Figure 4 A limiting protrusion 121 is provided on the lower cover 12. When the actuating part 3 is in the first position, the limiting hole 33 and the limiting protrusion 121 are misaligned, so that the limiting protrusion 121 abuts against the actuating plate 32, preventing the actuating plate 32 from moving in the pressing direction, and thus preventing the pressing part 2 from being pressed down. When the actuating part 3 is in the second position, the limiting hole 33 corresponds to the limiting protrusion 121, so that the limiting protrusion 121 and the actuating plate 32 are released from the limiting abutment effect, allowing the actuating plate 32 to move in the pressing direction, and thus allowing the pressing part 2 to be pressed down.

[0060] In another embodiment, please refer to Figure 10 The actuating plate 32 has a locking tongue 35 that can pass through the actuating groove 23 at one end, and the upper cover 11 has a limiting groove 112 corresponding to the locking tongue 35. When the actuating part 3 is in the first position, the locking tongue 35 can be inserted into the limiting groove 112, thereby realizing the limiting engagement between the actuating plate 32 and the upper cover 11 in the pressing direction, so that the actuating plate 32 cannot move in the pressing direction, and thus the pressing part 2 cannot be pressed down. When the actuating part 3 is in the second position, the locking tongue 35 can disengage from the limiting groove 112, thereby releasing the engagement between the actuating plate 32 and the limiting groove 112, so that the pressing part 2 can be pressed down.

[0061] Additionally, a self-locking mark 25 can be installed at the bottom of the actuating groove 23, please refer to [reference needed]. Figure 3 When the toggle part 3 is in the first position, the self-locking mark 25 is exposed relative to the toggle button 31, allowing the user to directly observe it, indicating that the battery cover 10 is in a self-locking state. When the toggle part 3 is in the second position, the toggle button 31 covers the self-locking mark 25, indicating that the battery cover 10 is unlocked. This method allows the user to intuitively observe the self-locking and unlocking states of the battery cover 10, facilitating user operation.

[0062] The actuating groove 23 also has a locking groove 27 and an unlocking groove 28 on its groove wall. Please refer to [reference needed]. Figure 6 A screw hole 34 is provided on the toggle key 31. Please refer to [reference needed]. Figure 9 A ball screw 5 is installed in the screw hole 34. The ball screw 5 moves with the toggle button 31. When the toggle part 3 is in the first position, the end of the ball screw 5 is in the locking groove 27. When the toggle part 3 is in the second position, the end of the ball screw 5 is in the unlocking groove 28. The cooperation between the ball screw 5 and the locking groove 27 and unlocking groove 28 allows the toggle part 3 to accurately reach the first or second position and apply a certain pressure at the corresponding position, ensuring the stability of the toggle part 3 in the first or second position. Furthermore, when switching between the first and second positions, the characteristics of the ball screw 5 can be used to give the user a clear operating feel, ensuring that the toggle part 3 can accurately switch between the first and second positions.

[0063] In addition, a spring can be provided on the toggle plate 32, with the other end of the spring abutting against the button 21, so that the spring provides elastic force for the toggle part 3 to move to the first position. This ensures that the battery cover 10 can be self-locked by the spring force without the intervention of external force. The spring can only be compressed when the user manually drives the toggle part 3, thereby effectively preventing the toggle part 3 from accidentally reaching the second position and preventing the user from accidentally touching the toggle button 31 and causing the battery cover 10 to open.

[0064] Please refer to Figure 2 The button 21 has outwardly extending blocks 22 on both sides. The extension blocks 22 are located between the upper cover 11 and the lower cover 12. The extension blocks 22 and the pressing hole 111 are mutually restricted in the pressing direction, thereby preventing the button 21 from coming out of the pressing hole 111. Of course, the setting of the extension blocks 22 does not affect the normal movement of the pressing part 2 in the pressing direction.

[0065] In this embodiment, the locking part 4 and the pressing part 2 are connected by contact. Please refer to [link / reference]. Figure 2 and Figure 5 The extension block 22 is provided with a first inclined surface 24 that slopes downward. The locking part 4 includes a latch 41 with a second inclined surface 45 on one side and a latch 42 provided on the other side of the latch 41. The first inclined surface 24 contacts the second inclined surface 45 to form a wedge structure. When the first inclined surface 24 moves downward, the second inclined surface 45 will move towards the pressing button 21. Conversely, when the first inclined surface 24 moves upward, it will push the second inclined surface 45 to move away from the pressing button 21.

[0066] The latch 41 is located between the upper cover 11 and the lower cover 12, and the latch 42 can penetrate the side wall of the upper cover 11. Thus, when the latch 42 extends out of the side wall of the upper cover 11, the locking part 4 can be locked relative to the battery compartment 40; when the latch 42 retracts into the upper cover 11, the locking part 4 can be unlocked relative to the battery compartment 40. Furthermore, due to the wedge engagement of the first inclined surface 24 and the second inclined surface 45, when the extension block 22 moves in the pressing direction, the first inclined surface 24 moves downward in the pressing direction, and the second inclined surface 45 moves towards the pressing button 21. The latch 42 can move towards the inside of the cover 1 and reach the unlocked position. Alternatively, when the extension block 22 moves in the opposite direction to the pressing direction, the first inclined surface 24 presses the second inclined surface 45, causing the second inclined surface 45 to move away from the pressing button 21. The latch 42 can move towards the outside of the cover 1 and reach the locked position.

[0067] It should be noted that, to ensure the locking effect of the battery cover 10, there are at least two locking parts 4, which are respectively arranged on both sides of the cover 1 to ensure a stable locking effect. The two locking parts 4 have the same structure, and only one locking part 4 will be described as an example here.

[0068] A first return spring 44 is provided between the latch 41 of the locking part 4 and the side wall of the upper cover 11 (refer to 2). The first return spring 44 can provide the locking part 4 with an elastic force to move toward the unlock position. When the pressing button 21 moves downward, the elastic force can make the latch 42 move automatically toward the unlock position, realizing the automatic unlocking of the battery cover 10. A second return spring 124 is provided between the pressing button 21 and the lower cover 12. The second return spring 124 can provide the pressing part 2 with an elastic force to move toward the upper cover 11. That is, when the pressing force of the pressing part 2 disappears, the elastic force can make the pressing button 21 automatically reset so that it can be pressed again when unlocking.

[0069] It should be noted that the elastic force provided by the second return spring 124 should be greater than that provided by the first return spring 44. That is, when the pressing force of the pressing part 2 disappears, the elastic force of the second return spring 124 can overcome the elastic force of the first return spring 44, so that the pressing button 21 reaches the upper cover 11. At this time, with the cooperation of the first inclined surface 24 and the second inclined surface 45, the latch 42 can automatically reach the locking position. In addition, the elastic force of the first return spring 44 and the second return spring 124 on the corresponding parts should be uniform and stable to avoid the situation where the elastic force on one side of the corresponding parts is large and the elastic force on the other side is small, which would affect the normal movement of the locking part 4 and the pressing part 2.

[0070] Furthermore, when there is no external force applied to the pressing part 2, the pressing part 2 will abut against the upper cover 11 on the outer edge of the pressing hole 111 under the action of the second return spring 124, at which time the position of the toggle part 3 can be adjusted. However, during the pressing process of the pressing part 2, the position of the toggle part 3 cannot be adjusted arbitrarily. For example, when the limiting boss 121 and the limiting hole 33 are inserted, the toggle part 3 cannot change position during the pressing process of the pressing part 2 due to the insertion state of the two. For another example, after the locking tongue 35 of the toggle plate 32 is disengaged from the locking groove 112, it can abut against the inner wall of the upper cover 11, thereby keeping the toggle part 3 stably in the second position. Only when the external force on the pressing part 2 disappears and it returns to the original position can the position of the toggle part 3 be adjusted, thereby avoiding the situation where the pressing part 2 cannot return to the original position due to the adjustment of the toggle part 3 during the pressing process.

[0071] In addition, please refer to Figure 2 and Figure 8 The lower cover 12 is provided with a guide groove 123 and a guide post 122. The locking pin 41 can engage with the guide groove 123 for limiting, thereby allowing the locking part 4 to slide stably along the guide direction of the guide groove 123; please refer to Figure 7 The pressing button 21 has a guide hole 29 that mates with the guide post 122, allowing the pressing part 2 to move stably along the guide direction of the guide post 122. The second return spring 124 can be embedded in the inner ring of the guide post 122 or sleeved on the outer circumference of the guide post 122, achieving an elastic connection between the pressing button 21 and the lower cover 12. Alternatively, several slots can be formed on the pressing button 21, with the second return spring 124 independently located on the outside of the guide post 122 and stably inserted into the slots. Similarly, a spring hole 43 can be provided on the locking pin 41, allowing the first return spring 44 to be stably inserted into the spring hole 43.

[0072] This application also provides a battery pack, please refer to... Figure 11 The battery pack includes the aforementioned battery cover 10 and a battery cell 20 fixedly connected to the cover body 1 of the battery cover 10. The battery cover and the battery cell can also be detachably connected.

[0073] This application also provides an infrared sight; please refer to... Figure 11 and Figure 12 The infrared sight includes a device body 30 and a battery pack. A battery compartment 40 is fixedly provided on the device body 30. A slot 50 is provided on the wall of the battery compartment 40 or on the device body 30. An elastic element 60 is provided at the bottom of the battery compartment 40. The elastic element 60 can be a spring.

[0074] The battery pack is the aforementioned battery pack including a battery cover 10 and battery cells 20. The battery cells 20 are placed inside the battery compartment 40. When the battery pack is installed in place, the bottom of the battery cell 20 can press against the elastic member 60, thereby providing the elastic member 60 with an elastic force to release the battery cell 20 from the battery compartment 40. In the first state, the actuating part 3 of the battery pack is located in the first position, and the pressing part 2 is fixed relative to the cover 1 in the pressing direction. At this time, the locking part 4 of the battery pack can be locked with the slot 50 in the locking position, thereby locking the battery pack relative to the battery compartment 40. In the second state, the actuating part 3 is located in the second position, and the pressing part 2 moves relative to the cover 1 in the pressing direction. Through the movement of the pressing part 2, the locking part 4 can be gradually moved to the unlocking position, thereby unlocking the locking part 4 from the slot 50 in the locking position, and thus unlocking the battery pack relative to the battery compartment 40.

[0075] Furthermore, when the battery pack is inserted into the battery compartment 40 of the device body 30, the toggle switch 31 needs to be moved to the second position, i.e., the battery cover 10 is released from self-locking. At this time, the user cannot see the self-locking mark 25 from the front. When the battery pack is inserted into the battery compartment 40 housing, the latches 42 of the main latches 41 on both sides retract inward under the pressure of the edge of the device column structure. When the user presses the battery pack into place, the latches 42 engage with the slots 50, and the battery pack is installed in place. At this time, the user can move the toggle switch 3 to the first position, and the battery cover 10 self-locks. At this time, the self-locking mark 25 is exposed, and the pressing part 2 cannot be pressed down, which has the effect of preventing accidental contact. If the user wants to remove the battery pack, the toggle switch 3 needs to be moved to the second position and the pressing part 2 needs to be pressed down forcefully. At this time, the locking parts 4 on both sides slide into the cover 1 under the action of the first return spring 44, the latches 42 disengage from the slots 50, and the battery pack pops out under the elastic force of the elastic member 60 in the battery compartment 40, so that the user can easily remove it for replacement.

[0076] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0077] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application.
