[0016] Please refer to Figure 1 and Figure 2 ,in, Figure 1 This is a three-dimensional assembly diagram of a key lock 10 with a modular structure provided by an embodiment of the present utility model. Figure 2 yes Figure 1The following is an exploded diagram of a key lock. The key lock 10 includes an electronic module 11, a mechanical module 12, a middle frame 13, and a locking beam 15. The middle frame 13 integrates and secures the electronic module 11, the mechanical module 12, and the locking beam 15 into a single unit. The locking beam 15 extends from the upper end of the middle frame 13, and the electronic module 11 is exposed from the side of the middle frame 13. In this embodiment, the key lock 10 operates using power provided by a battery 20. In other embodiments, the key lock 10 can operate using power provided by other devices.

[0017] In this embodiment, the middle frame 13 includes a body 130. The body 130 is a frame structure having an upper end, a lower end opposite the upper end, and side surfaces located between the upper and lower ends. The body 130 is provided with a first receiving space 132. The first receiving space 132 has an opening 131 on one side surface of the body 130. The electronic module 11 is received and fixed in the first receiving space 132 through the opening 131, and the password input device of the electronic module 11 is exposed through the opening 131 for user access. The electronic module 11 cooperates with the body 130 to form a second receiving space 134. The mechanical module 12 is received and fixed in the second receiving space 134, realizing mutual cooperation between the electronic module 11 and the mechanical module 12. The mechanical module 12 includes a locking device. The electronic module 11 controls the locking device to cooperate with the lock beam 15 to achieve locking or unlocking functions.

[0018] Please refer to Figure 3 and Figure 4 , Figure 3 and Figure 4 for Figure 1 The electronic module shown is a schematic diagram of an exploded view from two different angles. The electronic module 11 includes a front shell 111, a password input device 113, a drive member 114, a control board 115 and a bracket 117. The front shell 111 and the bracket 117 cooperate to form a third receiving space (not shown in the figure), and the password input device 113 and the control board 115 are accommodated in the third receiving space (not shown in the figure). The front shell 111 and the bracket 117 are fixed as a whole by a mechanical connection. The other components of the electronic module 11 are clamped between the front shell 111 and the bracket 117, making the electronic module 11 a modular integrated structure. The direction extending from the bracket 117 to the front shell 111 is defined as the first direction.

[0019] The control board 115 includes an electrode interface 1151, a sensor 1153, and a driver interface 1155. The electrode interface 1151 and the driver interface 1155 are located on a side of the control board 115 near the bracket 117 and near the lower end of the body 130. The sensor 1153 is located on a side of the control board 115 near the front housing 111. In this embodiment, the electrode interface 1151 is a positive and negative electrode interface; the relative positions of the positive and negative electrode interfaces are not limited. The number of sensors 1153 can be one or more, and in this embodiment, multiple sensors are used as an example for description.

[0020] The bracket 117 is provided with a control panel mounting groove 1171 . The control panel mounting groove 1171 is provided on a side of the bracket 117 close to the front housing. The outer edge of the control panel mounting groove 1171 has a protrusion 1172 .

[0021] The password input device 113 includes a button 1131 and a waterproof gasket 1133. The password input device 113, control panel 115, and bracket 117 are stacked sequentially on the front housing 111 along a first direction. The control panel 115, panel mounting slot 1171, and waterproof gasket 1133 are shaped to match each other, with the control panel 115 securely positioned within the panel mounting slot 1171. The waterproof gasket 1133 extends in the opposite direction of the first direction to form a sidewall 11331, which fits over the protrusion 1172 of the bracket 117. This ensures that the control panel mounting slot 1171 and the control panel 115, when secured within the slot, are tightly covered by the waterproof gasket 1133. Of course, in other embodiments, the positions of the protrusion 1172 and the side wall 11331 can be interchanged, that is, the protrusion 1172 is set on the waterproof pad 1133, and the side wall 11331 is set on the outer edge of the control board mounting groove 1171. The two are engaged so that the control board 115 is tightly covered by the waterproof pad 1133, thereby achieving a waterproof effect.

[0022] It should be noted that the waterproof pad 1133 is made of waterproof soft material and has a waterproof function. When the key lock 10 encounters water, it can protect the control board 115 from being affected. In this embodiment, the waterproof pad 1133 can be made of silicone.

[0023] There are multiple buttons 1131, each with a corresponding identifier. The identifier can be a number, letter, or other symbol, which is not specifically limited here. The sensor 1153 of the control panel 115 corresponds one-to-one with each button 1131 to sense whether the corresponding button 1131 is operated. In this embodiment, the sensor 1153 can be a pressure sensor or other type of sensor. The front housing 111 is provided with a button hole 1111 corresponding one-to-one with each of the multiple buttons 1131. The button 1131 extends from the button hole 1111 for operation (e.g., pressing) to enter password information. It should be noted that the number of buttons 1131, sensors 1513, and button holes 1111 can be increased or decreased according to actual circumstances. In some cases, the number of buttons 1131, sensors 1513, and button holes 1111 can be only one. The number of buttons 11311 and sensors 1513 does not need to correspond one-to-one and can be adjusted according to actual needs.

[0024] Bracket 117 is further provided with a first through-hole 1175, a receiving cavity 1173, and a second through-hole 1179. First through-hole 1175 corresponds one-to-one with electrode interface 1151, receiving cavity 1173 communicates with second receiving space 134, and second through-hole 1179 connects receiving cavity 1173 with a third receiving space (not shown). Driver 114 is partially housed in receiving cavity 1173, with one end of driver 114 passing through second through-hole 1179 to electrically connect to driver interface 1155 on control board 115, and the other end extending into second receiving space 134. To ensure waterproofing, the gap between driver 114 and second through-hole 1179 is filled with waterproof glue. In this embodiment, driver 114 may be a motor.

[0025] It will be appreciated that in this embodiment, a plurality of screw holes (not shown) are reserved along the first direction on the front housing 111, password input device 113, control board 115, and bracket 117. The electronic module 11 is assembled into an integrated structure by bolting, so that the electronic module 11 can be used as a standard component. In other embodiments, the electronic module 11 can be packaged using other methods, such as welding or adhesive curing.

[0026] Please also see Figure 5 , Figure 5 for Figure 1 The main body 130 is provided with a fourth receiving space 1301 , and the first receiving space 131 and the fourth receiving space 1301 are connected by a fixing frame opening 137 .

[0027] The middle frame 13 also includes a fixing frame 135. The fixing frame 135 has a door-like structure, comprising a cross arm 1351, a first clamping arm 1353, and a second clamping arm 1354. The cross arm 1351 connects the first and second clamping arms 1353 and 1354. The first clamping arm 1353 is provided with fixing posts 13531 that correspond one-to-one with the first through-holes 1175. The shape of the fixing frame opening 137 corresponds to that of the first clamping arm 1353, allowing the fixing frame 135 to be inserted into the fourth receiving space 1301 through the fixing frame opening 137 and secured therein. The fixing posts 13531 are located on the side of the first clamping arm 1353 that is closest to the first receiving space 131.

[0028] In this embodiment, a sealing gasket 138 is used to waterproof the electrode interface 1151 of the control board 115. The sealing gasket 138 and the fixing bracket 135 are stacked on the bracket 117 in a first direction, with the first clamping arm 153 abutting the sealing gasket 138. The sealing gasket 138 defines a third through-hole 1381, which corresponds one-to-one with the first through-hole 1175. The fixing post 13531 passes through the third through-hole 1381 of the sealing gasket 138 and the first through-hole 1175 of the bracket 117, abutting the electrode interface 1151 of the control board 115.

[0029] It should be noted that in this embodiment, the number of the first through hole 1175, the third through hole 1381 and the fixing post 13531 are all two. In other embodiments, the number of the first through hole 1175, the third through hole 1381 and the fixing post 13531 varies with the actual configuration of the electrode interface 1151.

[0030] The mounting bracket 135 also includes a passageway 1357. One end of the conductive wire 136, which connects the battery 20 to the control board 115, is received in the passageway 1357 and electrically connected to the battery 20. The other end of the conductive wire 136 is wound into a spiral and sleeved around the fixing post 13531. The wire passes through the third through-hole 1381 and the first through-hole 1175 along with the fixing post 13531, and finally electrically connects to the electrode interface 1151 of the control board 115. The gap between the first through-hole 1175, the fixing post 13531, and the conductive wire 136 is filled with waterproof glue. In other embodiments, the conductive wire 136 can be replaced by a conductive sheet.

[0031] It should be noted that to achieve waterproofing, the sealing gasket 138 is made of a soft, waterproof material. This provides a waterproof function, protecting the control board 115 from damage when the key lock 10 comes into contact with water. In this embodiment, the sealing gasket 138 may be made of silicone. It will be appreciated that while the sealing gasket 138 protects the control board 115 from damage when exposed to water, the gaps between the first through-hole 1175, the fixing post 13531, and the conductive wire 136 are filled with waterproof glue, which not only enhances the waterproofing effect but also helps to improve the stability of the electrical connection between the conductive wire 136 and the control board 115.

[0032] In one embodiment, the key lock 10 is powered by a built-in battery 20. A battery compartment 133 is provided inside the key lock 10 to accommodate and secure the battery 20.

[0033] Please refer to Figure 1 、 Figure 5 and Figure 6 ,in, Figure 1 This is a schematic diagram of the three-dimensional structure of a key lock provided by an embodiment of the utility model. Figure 5 for Figure 1 The exploded diagram of the middle frame shown in FIG. Figure 6 for Figure 1 The battery compartment is shown as a schematic diagram of the three-dimensional structure of the battery compartment in the state of receiving the battery. The middle frame 13 also includes a battery compartment 133, which receives the battery 20. The battery compartment 133 is received within the fourth receiving space 1301 of the main body 130. In this embodiment, the battery 20 is a button-type battery, and the number is two. In other embodiments, the battery 20 does not necessarily need to be a button-type battery, and the number of batteries 20 can be set as needed, and can be one or more.

[0034] The middle frame 13 also includes an installation opening 139, through which the battery compartment 133 can be removed or installed into the fourth receiving space 1301, facilitating replacement of the battery 20. In this embodiment, the installation opening 139 is provided at the lower end of the middle frame 13, and the fourth receiving space 1301 is provided near the lower end of the middle frame 13 and communicates with the outside world through the installation opening 139. After the fixing frame 135 is inserted into the fourth receiving space 1301 through the fixing frame opening 137, the battery compartment 133 containing the battery 20 can be installed into the fourth receiving space 1301 through the installation opening 139 and clamped between the first clamping arm 1353 and the second clamping arm 1354 of the fixing frame 135. The clamping of the fixing frame 135 fixes the battery compartment 133, making it difficult for the battery compartment 133 to easily withdraw from the main body 130 through the installation opening 139; and the shape of the fixing frame opening 137 does not match the battery compartment 133, so the fixing frame 135 that clamps the battery compartment 133 cannot withdraw from the main body 130 through the fixing frame opening 137. As a result, the fixing frame 135 and the battery compartment 133 cooperate and fix each other.

[0035] Furthermore, the battery compartment 133 is provided with a receiving and fixing portion 1333 for mounting and fixing the battery 20. An outer cover 1335 is provided at one end of the receiving and fixing portion 1333. The connection between the receiving and fixing portion 1333 and the outer cover 1335 forms a neck 13331. The outer cover 1335 is shaped to correspond to the mounting opening 139 of the middle frame 13. To achieve waterproofing, a sealing ring 13332 is provided on the neck 13331. When the battery compartment 133 is installed in the fourth receiving space 1301, the sealing ring 13332 forms an interference fit with the inner wall of the mounting opening 139, thereby protecting the internal components of the key lock 10 from damage when exposed to water.

[0036] It should be noted that the sealing ring 13332 is made of waterproof soft material and has a waterproof function. In this embodiment, the sealing ring 13332 can be made of silicone or rubber.

[0037] Please refer to Figure 2 and Figure 7 ,in, Figure 2 yes Figure 1 The exploded diagram of the key lock is shown in the figure. Figure 7 for Figure 1 The mechanical module 12 includes a locking device 121, an upper cover 123, and a lower cover 125, wherein the upper cover 123 and the lower cover 125 cooperate to form a fifth receiving space (not shown) for receiving the locking device 121. The upper cover 123 and the lower cover 125 are fixed as a whole by a mechanical connection. The locking device 121 is clamped between the upper cover 123 and the lower cover 125, making the mechanical module 12 a modular integrated structure. The locking device 121 includes a first marble 1211 and a second marble 1212 that abut against each other, and a third marble 1213 that is spaced apart from the second marble 1212.

[0038] The locking device 121 also includes a limit member 1215 and a reset member 1217. The reset member 1217 is sleeved on the end of the limit member 1215 close to the upper end of the main body 130, and one end of the reset member 1217 is connected to or abuts the second marble 1212, and the other end is connected to or abuts the third marble 1213. In this embodiment, the elastic member 155 can be a spring. The lower cover 125 is provided with a fourth through hole 1251, and a portion of the limit member 1215 extends from the fourth through hole 1251 and is accommodated and fixed in the fifth accommodation space (not shown). Since the mechanical module 12 is accommodated in the second accommodation space 134, the portion of the limit member 1215 exposed from the lower cover 125 is movably connected to the end of the driving member 114 extending into the second accommodation space 134, thereby realizing the connection between the electronic module 11 and the mechanical module 12. The control board 115 of the electronic module 11 can control the locking device 121 by controlling the driving member 114.

[0039] The lock beam 15 is roughly U-shaped and includes two arms. The lock beam 15 also includes a lock tongue 151, a first locking groove 153 for accommodating the first marble 1211, a second locking groove 154 for accommodating the third marble 1213, and an elastic member 155. Among them, the lock tongue 151 and the first locking groove 153 are arranged on one arm of the lock beam 15, the first locking groove 153 is located above the lock tongue 151, and the second locking groove 154 is correspondingly arranged on the other arm of the lock beam 15. The elastic member 155 is arranged at the bottom of the lock tongue 151 to provide an upward thrust for the lock tongue 151. The main body 130 of the middle frame 13 is correspondingly provided with a lock tongue mounting groove 1303, and the bracket 117 is provided with a fixing groove 1177 corresponding to the lock tongue mounting groove 1303. The fixing groove 1177 cooperates with the lock tongue mounting groove 1303 to fix the lock tongue 151 and the elastic member 155.

[0040] Specifically, one side of the first marble 1211 abuts against the inner wall of the first locking groove 153, and the other side abuts against the second marble 1212. One side of the third marble 1213 abuts against the inner wall of the second locking groove 154, and the other side abuts against the limiter 1215. The limiter 1215 is arranged between the second marble 1211 and the third marble 1213. Furthermore, the first locking groove 153 and the second locking groove 154 are both arc concave structures, so that the first locking groove 153 and the second locking groove 154 can fit tightly with the corresponding marbles when accommodating the first marble 1211 and the third marble 1213.

[0041] The limiting member 1215 includes two arc concave structures 12151 arranged in opposite directions. Specifically, when the key lock 10 is in the open state, the arc concave structures 12151 arranged in opposite directions respectively accommodate the second marble 1212 and the third marble 1313, and the first marble 1211, the second marble 1212 and the third marble 1213 are arranged in a straight line.

[0042] It will be appreciated that in this embodiment, the upper cover 123 and the lower cover 125 are provided with a plurality of screw holes (not shown) corresponding to the normal direction of the first direction, and the mechanical module 12 is installed as an integrated structure using bolts, so that the mechanical module 12 can be used as a standard component. In other embodiments, the mechanical module 12 can be packaged using other methods, such as welding or adhesive curing. In addition, the upper cover 123, the lower cover 125, and the bracket 117 are provided with a plurality of bolt holes corresponding to the first direction, and the electronic module 11 and the mechanical module 12 are further fixed together by bolts.

[0043] See also Figure 8 , showing the three-dimensional structure of the key lock 10 in the locked and unlocked states respectively, in order to show the working relationship between the locking device 121 and the lock beam 15 and the driving member 117, Figure 8Some components of the electronic module 11 and the mechanical module 12 are not shown. It is understood that in the actual assembly process, the electronic module 11 and the mechanical module 12 are still modular integrated structures. The working principle of the key lock 10 is as follows:

[0044] To unlock the door, a password is entered through the password input device 113. The control panel 115 determines that the entered password is correct and controls the rotation of the driver 114. Since the limiting member 1215 is movably connected to the driver 114, it further drives the limiting member 1215 to rotate accordingly, causing the two arcuate concave structures 12151 to move toward the second and third marbles 1212, 1213, respectively. The rotation of the limiting member 1215, after being driven by the reset member 1217, forces the second and third marbles 1212, 1213 to move toward the limiting member 1215. Simultaneously, because the elastic member 155 provides an upward thrust to the lock tongue 151, the two arms of the lock beam 15 respectively exert a thrust on the first and third marbles 1211, 1213, toward the limiting member 1215. The action of these two components causes the first, second, and third marbles 1211, 1212, and 1213 to move toward the two arcuate concave structures 12151. When the first marble 1211 and the third marble 1213 leave the first locking groove 153 and the second locking groove 154 respectively, the lock tongue 151 pops out of the middle frame 13 to unlock the smart lock 10.

[0045] When locking, the control panel 115 controls the rotation of the driving member 114, and the limiting member 1215 connected to the driving member 114 also rotates accordingly. Furthermore, the rotation of the limiting member 1215, after being transmitted by the reset member 1217, causes the second marble 1212 and the third marble 1213 to respectively leave the two arc concave structures 12151. Under the push of the reset member 1217, the first marble 1211 and the third marble 1213 are respectively accommodated in the first locking groove 153 and the second locking groove 154. At this time, the first locking groove 153, the second locking groove 154, the first marble 1211, the second marble 1212, the third marble 1213 and the limiting member 1215 are arranged in a straight line, realizing the locking of the smart lock 10;
