DETAILED DESCRIPTION

[0024] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0025] refer to Figures 1 to 4 As shown, the utility model discloses a battery compartment structure of a lock, comprising a lock body 1, a battery compartment 2, an elastic member 3, a rotating buckle 4 and a linkage mechanism;

[0026] A battery compartment inlet and outlet 11 is provided on the side of the lock body 1;

[0027] The battery compartment 2 is movably fitted in the battery compartment inlet and outlet 11, and a limiting groove 21 is provided on the side of the inner end thereof;

[0028] The elastic member 3 is arranged between the inner end surface of the battery compartment 2 and the lock body 1, and is used to pop out the battery compartment 2;

[0029] The rotating buckle 4 is rotatably fitted in the lock body 1, and a hook 41 is provided at the first end thereof to be hooked in the limiting groove 21 by elastic activity, so that the battery compartment 2 compresses the elastic member 3 without being ejected;

[0030] The linkage mechanism is linked to rotate the buckle 4 when or after the lock is unlocked to make the hook 41 disengage from the limiting groove 21 .

[0031] Through the above scheme, the utility model sets a linkage mechanism so that the unlocking action of the lock is linked to the action of the rotating buckle 4. After the user unlocks the lock using a key or through identity recognition, when the knob 20 of the lock is rotated to a certain angle, the linkage structure can be used to make the hook 41 of the rotating buckle 4 disengage from the limiting groove 21 of the battery compartment 2, and the battery compartment 2 is no longer stuck and will be popped out by the elastic member 3, thereby realizing the opening of the battery compartment 2, which is convenient for replacing the battery. The battery compartment 2 can be popped out by turning the knob 20, and the operation is relatively convenient and quick. Since the battery compartment inlet and outlet 11 are arranged on the side of the lock body 1, the battery compartment 2 can be opened without disassembling the entire lock. At the same time, the prerequisite for opening the battery compartment 2 is that the lock is unlocked, that is, the battery compartment 2 can be popped out only in the unlocked state, and the safety of the lock can also be guaranteed.

[0032] Specific embodiments of the present utility model are shown below.

[0033] The above-mentioned linkage mechanism includes a slider 5, a rotating shaft 6 and a cam 7; the slider 5 is slidably fitted in the lock body 1, and its first end is opposite to the second end of the rotating buckle 4; the rotating shaft 6 rotatably penetrates the lock body 1; the end of the rotating shaft 6 located inside the door is coaxially connected to the lock tongue 10 of the lock, and the end located outside the door is coaxially connected to the knob 20 of the lock; the cam 7 is arranged on the axis of the rotating shaft 6 and is opposite to the second end of the slider 5; the convex portion 71 of the cam 7 abuts against the second end of the slider 5 as the rotating shaft 6 rotates and pushes the slider 5 to move, thereby rotating the rotating buckle 4 to realize that the hook 41 disengages from the limiting groove 21, so that the battery compartment 2 is ejected out of the battery compartment inlet and outlet 11 by the elastic member 3.

[0034] In this embodiment, the lock is an elongated lock as a whole, so the battery compartment inlet and outlet 11 can be set on the end surface of the lock body 1, preferably the upper end surface, which is easier to observe and take out the battery compartment 2.

[0035] In this embodiment, limiting grooves 21 are symmetrically provided on both side surfaces of the inner end of the battery compartment 2, the number of rotating buckles 4 is designed to be two, and a tension spring 8 is connected between the hooks 41 of the two rotating buckles 4. The elastic force of the tension spring 8 allows the two rotating buckles 4 to be reset at the same time, so that the two hooks 41 are tightly fitted in the limiting grooves 21 on both sides of the battery compartment 2; correspondingly, the first end of the slider 5 is provided with an arc surface 51 for the second ends of the two rotating buckles 4 to flexibly fit.

[0036] The elastic member 3 is a spring fixed in the lock body 1. In this embodiment, there are two springs, which makes the structure more stable.

[0037] Furthermore, the spring is made of a conductive material and is electrically connected to the circuit board of the lock; a conductive column that movably contacts the spring is provided in the battery compartment 2. With this structure, the elastic member 3 and the conductive column can be used as one of the electrodes of the lock, simplifying the circuit connection structure inside the lock, making the product structure more delicate and compact.

[0038] The end surface of the hook 41 is provided with a guide bevel 411 for the side of the inner end of the battery compartment 2 to flexibly cooperate with. Since the hook 41 can automatically reset by elasticity (see the tension spring 8 above), when the battery compartment 2 is completely taken out, the hook 41 will reset and block the trajectory of the battery compartment 2 entering the lock body 1. By providing the guide bevel 411, the hook 41 can be pushed outwards during the process of the battery compartment 2 being pushed into the lock body 1, so that the battery compartment 2 can be pushed in without turning the knob 20, and the battery compartment 2 can be quickly loaded.

[0039] The second end of the rotating buckle 4 is provided with a swing arm 42 for the first end of the slider 5 to movably abut. The swing arm 42 and the hook 41 form an angle of about 90°, so that when the swing arm 42 is pushed by the slider 5, the rotating buckle 4 drives its hook 41 to move in the direction of leaving the limiting groove 21 (i.e., away from the side of the battery compartment 2).

[0040] The lock body 1 is provided with a slide groove 12 for the sliding block 5 to slide with.

[0041] Both sides of the convex portion 71 are chamfered so as to more smoothly contact with the second end of the slider 5 and push the slider 5 .

[0042] The rotation process of the above-mentioned rotating shaft 6 is set as follows: 0° is the locked state of the lock (see Figure 2 ), 90° is the unlocked state of the lock, and 150° is the battery compartment pop-up state of the lock, that is, when unlocking normally, the user can unlock the lock by turning the knob 20 to 90° (see Figure 3 ), at this time, the convex portion 71 of the cam 7 is still not in contact with the slider 5, and the battery compartment 2 will not be ejected, avoiding affecting the normal use of the lock; and when the user needs to open the battery compartment 2, after normal unlocking, it is necessary to continue to turn the knob 20 to 150 degrees, at which time the battery compartment 2 will be ejected and the battery can be replaced (see Figure 4 ).

[0043] The lock of this embodiment can be unlocked by a key or by identity recognition, such as fingerprint, voiceprint, iris, ID card, etc. In order to further improve security, a limit mechanism can be designed for the rotation angle of the knob 20, which allows the knob 20 to rotate only 90°, that is, the knob 20 cannot rotate to 150° when the limit mechanism is not unlocked. The limit mechanism can only be unlocked by a key (which can be achieved through the positional relationship between the key and the lock core). In this way, the product can be designed so that the battery compartment 2 can only be unlocked by a key to avoid accidental touch or unauthorized opening of the battery compartment 2.

[0044] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
