[0031] Combine the following Figure 1-Figure 3 The locking assembly of the utility model is described.

[0032] The utility model provides a locking assembly, referring to Figures 1 to 3 , which comprises: a main body 10, a locking tongue 20 and a side slider 30. The main body 10 has a first slot 11 and a second slot 12 connected to the first slot 11. The side slider 30 can be slidably installed in the second slot 12, and the locking tongue 20 can be slidably installed in the first slot 11. The sliding direction of the side slider 30 is perpendicular to the sliding direction of the locking tongue 20. The side slider 30 is arranged against one side of the locking tongue 20, and the end of the locking tongue 20 is provided with a first locking portion 21 that can cooperate with the member to be locked. Figure 2 and Figure 3 As shown, one of the side slider 30 and the locking tongue 20 is provided with a first limiting groove 22 , and the other is provided with a first limiting block 31 convexly, and the first limiting block 31 is adapted to the first limiting groove 22 .

[0033] One side wall of the first groove body 11 has a first opening, and one end of the locking tongue 20 provided with the locking portion extends out of the first groove body 11 through the first opening. One side wall of the second groove body 12 has a second opening, and the second opening is located on one side wall of the first groove body 11, so that the interior of the first groove body 11 is connected with the interior of the second groove body 12. When the side slider 30 slides along the second groove body 12, it can extend out of the second groove body 12 from the second opening and contact one side of the locking tongue 20.

[0034] like Figure 4As shown, the first locking portion 21 is a protrusion arranged at the end of the lock tongue 20, thereby forming a first step surface at the end of the lock tongue 20. A notch is provided at one end of the member to be locked close to the lock tongue 20, forming a second step surface. The lock tongue 20 slides out of the first slot 11, and the protrusion is accommodated in the notch, so that the first step surface fits with the second step surface, thereby pressing and fixing the member to be locked in the target position. In addition, the first locking portion 21 can also be a socket, and correspondingly, a protrusion is provided at the end of the member to be locked, and the protrusion is inserted into the socket, which can also fix the member to be locked in the target position to prevent the member to be locked from moving accidentally. Alternatively, the first locking portion 21 is a protrusion, and correspondingly, the member to be locked is provided with a socket that cooperates with the protrusion.

[0035] Optional, such as Figure 2 As shown, the first limit block 31 is arranged at the end of the side slider 30, and correspondingly, the first limit groove 22 is located on the lock tongue 20. Of course, the first limit groove 22 can also be arranged on the side slider 30, and the protrusion can be arranged on the lock tongue 20. When the locking assembly is in the unlocked state, as shown in FIG. Figure 2 As shown, the first limit block 31 is clamped in the first limit groove 22 to restrict the movement of the lock tongue 20 along the first direction; the side slider 30 cooperates with the groove wall of the first groove body 11 to restrict the movement of the lock tongue 20 along the second direction, thereby stabilizing the lock tongue 20 and preventing the lock tongue 20 from falling out of the first groove body 11. The first direction is the sliding direction of the lock tongue 20, and the second direction is the sliding direction of the side slider 30.

[0036] When the locking member needs to be locked, the side slider 30 moves away from the locking tongue 20. Figure 3 As shown, the first limit block 31 is disengaged from the first limit groove 22, and the lock tongue 20 slides along the first slot body 11, so that the first locking portion 21 cooperates with the part to be locked to achieve locking. At this time, the side slider 30 can push the lock tongue 20 from the side to restrict the freedom of movement of the lock tongue 20 in the first slot body 11. When unlocking is required, the lock tongue 20 slides in a direction away from the part to be locked, the first locking portion 21 is disengaged from the part to be locked, and the side slider 30 slides toward the lock tongue 20, as shown in FIG. Figure 2 As shown, the first limiting block 31 is clamped in the first limiting groove 22, so as to constrain the locking tongue 20 in the first groove body 11 to prevent it from falling out.

[0037] The locking assembly provided by the embodiment of the utility model has a sliding direction of the lock tongue 20 and the side slider 30 that is perpendicular, and the end of the lock tongue 20 is provided with a first locking portion 21 that cooperates with the piece to be locked, and the first locking portion 21 can cooperate with or unlock the piece to be locked as the lock tongue 20 slides in the first slot body 11, and the side slider 30 and the lock tongue 20 have a matching first limiting groove 22 and a first limiting block 31, and the first limiting groove 22 and the first limiting block 31 cooperate to constrain the lock tongue 20 in the first slot body 11 to prevent the lock tongue 20 from falling out of the first slot body 11 in the unlocked state.

[0038] like Figure 2 As shown, the structural member in which the first limiting groove 22 is provided in the side slider 30 and the locking tongue 20 is also provided with a second limiting groove 23 . When the locking portion is disengaged from the member to be locked, the first limiting block 31 is received in the second limiting groove 23 .

[0039] like Figure 2 and Figure 3 As shown, the second limiting groove 23 and the first limiting groove 22 are arranged in parallel on the lock tongue 20, and the notches of both are facing the side slider 30. When the locking assembly is in the state of locking the member to be locked, the first limiting block 31 is received in the second limiting groove 23. Optionally, the side slider 30 can push the lock tongue 20 from the side to constrain the position of the lock tongue 20 in the first groove body 11. When the locking assembly is in the unlocked state, the limiting protrusion is clamped in the first limiting groove 22. Figure 2 As shown, the second limiting groove 23 is formed by a notch provided at the end of the locking tongue 20. Of course, the second limiting groove 23 can also be adapted to the size of the first limiting block 31, and is snap-fitted.

[0040] For the stability of the connection, the side slider 30 and the locking tongue 20 are provided with a first limit block 31 and a second limit block 32, and a third limit groove is formed between the first limit block 31 and the second limit block 32, and a third limit block is formed between the first limit groove 22 and the second limit groove 23. When the locking assembly is in the unlocked state, the first limit block 31 is clamped in the first limit groove 22, and the third limit block is clamped in the third limit groove, so as to strengthen the constraint on the locking tongue 20 and prevent it from falling out of the first groove body 11. Figure 2 and Figure 3 As shown, the second limiting groove 23 and the first limiting groove 22 are arranged in parallel on the lock tongue 20, and the first limiting block 31 and the second limiting block 32 are convexly arranged in parallel on the side slider 30. When the locking assembly is in the unlocked state, the first limiting block 31 and the second limiting block 32 are both received in the second limiting groove 23.

[0041] It is understandable that the first limiting groove 22 and the second limiting groove 23 may also be provided on the side sliding block 30 , and correspondingly, the first limiting block 31 is provided on the side sliding block 30 .

[0042] like Figure 2 and Figure 3 As shown, the locking assembly further includes a first elastic member 40, one end of the first elastic member 40 is connected to the groove wall of the first groove body 11, and the other end of the first elastic member 40 is connected to the end of the locking tongue 20 away from the locking portion. It can be understood that the first elastic member 40 and the groove wall of the first groove body 11 and the end of the locking tongue 20 can be fixedly connected or abutted, as long as the first elastic member 40 can be fixed between the groove wall of the first groove body 11 and the locking tongue 20.

[0043] like Figure 2 As shown, the first elastic member 40 is a spring, and the spring is clamped between one end of the lock tongue 20 away from the locking portion and the groove wall of the first groove body 11. Optionally, when the locking assembly locks the member to be locked, the first elastic member 40 is in a natural state; or, when the locking assembly locks the member to be locked, the first elastic member 40 can push the lock tongue 20, so that the lock tongue 20 and the member to be locked are closely matched, thereby improving the stability of the locked state. When unlocking is required, the side slider 30 is pushed to move in a direction away from the lock tongue 20, so that the first limit block 31 is disengaged from the second limit groove 23, and the lock tongue 20 and the side slider 30 are unlocked; then the lock tongue 20 can move in a direction away from the member to be locked until the first limit block 31 is clamped in the first limit groove 22. At this time, the first elastic member 40 accumulates energy. With the cooperation of the first limit block 31 and the first limit groove 22, the lock tongue 20 is prevented from being disengaged from the first groove body 11 under the action of the first elastic member 40 that accumulates energy.

[0044] When it is necessary to lock the part to be locked, the side slider 30 slides away from the locking tongue 20, so that the first limit block 31 is disengaged from the first limit groove 22, and the first elastic member 40 releases the elastic force, pushing the first locking portion 21 to cooperate with the part to be locked to achieve automatic locking.

[0045] By providing the first elastic member 40 , during the locking process, it is only necessary to push the side slider 30 , and the locking tongue 20 can be automatically popped out under the action of the first elastic member 40 , so that locking is convenient.

[0046] Specifically, Figure 3 As shown, the locking tongue 20 is provided with a first receiving groove 24, one end of the first elastic member 40 is inserted into the first receiving groove 24, and the other end abuts against the groove wall of the first groove body 11, so that the first elastic member 40 is clamped between the groove bottom of the first receiving groove 24 and the groove wall of the first groove body 11.

[0047] The first receiving groove 24 provides guidance for the first elastic member 40 to prevent the first elastic member 40 from tilting during deformation, thereby preventing the locking tongue 20 from getting stuck in the first groove body 11 .

[0048] There are multiple first elastic members 40 , and the multiple first elastic members 40 are arranged in parallel. Correspondingly, the locking tongue 20 is provided with multiple first receiving grooves 24 , and the multiple first receiving grooves 24 are arranged one-to-one correspondingly to the multiple first elastic members 40 .

[0049] like Figure 3 As shown, there are two first elastic members 40 , and the locking tongue 20 is provided with two first receiving grooves 24 . The two first receiving grooves 24 are arranged in a one-to-one correspondence with the two first elastic members 40 .

[0050] Optionally, a groove 13 is provided on a groove wall of the first groove body 11 away from the first locking portion 21, and the notch of the groove 13 faces the interior of the first groove body 11, so that the first groove body 11 is connected with the groove 13. The lock tongue 20 is provided with a boss corresponding to the groove 13, and the boss is adapted to the groove 13. The boss forms a first step surface on the end surface of the lock tongue 20, and the groove 13 forms a second step surface on the groove wall of the first groove body 11. When the locking assembly is in the unlocked state, the first limit block 31 is clamped in the first limit groove 22, and the first step surface is abutted against the second step surface to form a constraint.

[0051] When two first elastic members 40 are provided, one of the first elastic members 40 is against the bottom of the groove 13, and the other first elastic member 40 is against the groove wall of the groove 13 provided in the first groove body 11, so that the two first elastic members 40 are provided in one-to-one correspondence with the two parallel surfaces of the second step surface.

[0052] like Figure 2 and Figure 3 As shown, the locking assembly further includes a second elastic member 50, one end of which is connected to the groove wall of the second groove body 12, and the other end of the second elastic member 50 is connected to the side slider 30. It can be understood that the second elastic member 50 can be set against or fixedly connected to the side slider 30 and the groove wall of the second groove body 12, as long as the second elastic member 50 can be sandwiched between the side slider 30 and the groove wall of the second groove body 12.

[0053] The second elastic member 50 is a spring or a memory alloy or other elastic structural member. Figure 3 As shown, the side slider 30 is provided with a second receiving groove 33 , a portion of the second elastic member 50 is received in the second receiving groove 33 , and another portion of the second elastic member 50 extends out of the second receiving groove 33 and abuts against the groove wall of the second groove body 12 .

[0054] When the locking assembly is in the unlocked state, the second elastic member 50 pushes the side slider 30 to abut against one side of the lock tongue 20, and cooperates with the groove wall of the first groove body 11 to constrain the movement freedom of the lock tongue 20 along the second direction. At this time, the first limit block 31 is clamped in the first limit groove 22. When it is necessary to lock the part to be locked, the side slider 30 is pushed to make the first limit block 31 escape from the first limit groove 22. The lock tongue 20 pops out under the action of the first elastic member 40, so that the first locking part 21 cooperates with the part to be locked. After the side slider 30 is released, the second elastic member 50 rebounds and pushes the side slider 30 to abut against one side of the lock tongue 20 again.

[0055] In one embodiment, the opposite side groove walls of the first groove body 11 fit with the two sides of the side slider 30 to play a guiding role. In another optional embodiment, the opposite side groove walls of the second groove body 12 are provided with guide grooves, and the opposite sides of the side slider 30 have guide blocks adapted to the guide grooves. The second groove body 12 can be provided with a guide groove only on a single side groove wall, or can be provided with guide grooves on two opposite groove walls. Among them, the guide blocks are in the shape of long strips and are provided one by one with the guide grooves. The guide blocks can be convexly provided on the side walls of the side slider 30, or the side slider 30 can be clamped in the guide groove along the thickness direction to serve as guide blocks.

[0056] Specifically, Figure 4 As shown, the main body 10 includes a base 15 and a cover plate 16. The second slot body 12 and the first slot body 11 are both arranged on the base 15. The base 15 is fixedly connected to the cover plate 16 so that the cover plate 16 and the bottom of the second slot body 12 form opposite side slot walls of the guide slot.

[0057] The base 15 and the cover 16 are respectively provided with fastening holes, and the fasteners 60 pass through the fastening holes to fix the base 15 and the cover 16. The main body 10 includes the base 15 and the cover 16 which are separately arranged, so as to facilitate the assembly of the components. Figure 3 As shown, two fasteners 60 are disposed near two sides of the cover plate 16 so that the base 15 and the cover plate 16 are fixedly connected.

[0058] The locking tongue 20 has a concave surface 25, which can fit the shape of a human fingertip.

[0059] like Figure 1 As shown, in order to facilitate pushing the lock tongue 20, a concave surface 25 is provided on the outer surface of the lock tongue 20. The shape of the concave surface 25 is adapted to the shape of the fingertips of the human body, which is convenient for pushing by fingers.

[0060] Combine the following Figure 4-Figure 5 The utility model describes a battery compartment.

[0061] The utility model also provides a battery compartment, such as Figure 4 and Figure 5 As shown, it includes a battery can 80, a battery cover 70 and the locking assembly as described above, the battery cover 70 can be opened and closed and installed at the opening of the battery can 80, and the main body 10 is fixedly connected to the battery can 80. The battery cover 70 is provided with a second locking portion 71, one of the first locking portion 21 and the second locking portion 71 is a card slot, and the other is a card block, and the card block can be carded in the card slot.

[0062] In one embodiment, one end of the battery cover 70 is rotatably connected to the battery barrel 80. For example, the battery barrel 80 has two ears, and connecting shafts are protruding from opposite sides of the battery cover 70, and the two connecting shafts are inserted between the two ears in a one-to-one correspondence. Alternatively, the battery barrel 80 and the battery cover 70 are provided with corresponding connecting holes, and the rotating shaft is inserted into the connecting hole, and the battery cover 70 is rotatably connected to the battery barrel 80 through the rotating shaft.

[0063] like Figure 4 As shown, the first locking portion 21 is a block disposed at the end of the locking tongue 20, and the second locking portion 71 is a slot. Figure 5 As shown, the card slot is a notch provided at the end of the battery cover 70, thereby forming a third step surface at the end of the battery cover 70. Correspondingly, one side surface of the card block is flush with the lock tongue 20, and a fourth step surface is formed at the end of the lock tongue 20. When the first locking portion 21 cooperates with the second locking portion 71, the fourth step surface is laid on the third step surface. Alternatively, the card slot is a blind hole provided at the end of the battery cover 70, and correspondingly, a card block is provided at the end of the lock tongue 20. It is understandable that when the card block is mounted in the card slot, the surface of the lock tongue 20 and the surface of the battery cover 70 smoothly transition, thereby improving the aesthetics after locking.

[0064] In order to facilitate opening of the battery cover 70, a groove 72 is provided on the surface of the battery cover 70. Figure 4 and Figure 5 As shown, the groove 72 is arranged close to the second locking portion 71 .

[0065] The battery compartment provided by the embodiment of the utility model can lock the battery cover 70 on the battery tube 80 by the locking assembly, so as to prevent the battery cover 70 from being opened accidentally, thereby improving the sealing and impact resistance of the battery compartment.
