A touch panel is provided on the second lock body, and the touch panel is connected to the processor via a wire. A second handle is rotatably connected to the second lock body, and one end of the shaft extends into the second handle.

[0009] The technical effects and advantages of this utility model are as follows:

[0010] The combined action of the limiting spring and the positioning rubber plate effectively mitigates the impact force generated by the collision between the door panel and the door frame.

[0011] The limit spring is sleeved on the square shaft and can extend and retract axially to absorb longitudinal force, preventing the square shaft from separating from the lock cylinder; the positioning rubber plate is made of elastic material and fills the gap between the lock cylinder and the lock body through a snap-fit ​​structure, buffering radial shaking and preventing the lock cylinder from loosening and falling off.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] The lock with shock absorption and protection function disclosed in this embodiment aims to solve the problem of lock cylinder structure falling off due to impact between the door panel and the door frame in existing electronic locks. By optimizing the lock body connection structure and electrical control module, stable operation of the lock cylinder and intelligent unlocking function are achieved.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the lock with shock absorption and protection function in this embodiment includes:

[0021] First lock body 1: It is detachably connected to the second lock body 2 by bolts to form an integral lock frame.

[0022] The second lock body 2 is made of the same material as the first lock body 1. Its surface is embedded with a touch panel 10 and is rotatably connected to a second handle 11. The second handle 11 is rotatably engaged with the second lock body 2 through a bearing.

[0023] Connection component: disposed between the first lock body 1 and the second lock body 2, specifically including:

[0024] Lock cylinder 3: Internally integrated electromagnetic drive mechanism for controlling the extension and retraction of the bolt;

[0025] Square shaft 4: Both ends extend into the square grooves of the first handle 7 and the second handle 11 respectively, realizing the mechanical linkage between the handle and the lock cylinder;

[0026] Limiting spring 5: Sleeve on one end of square shaft 4 near the first lock body 1, providing axial buffer force when the lock body is impacted;

[0027] Positioning rubber plate 6: Its edge is provided with a boss that engages with the first lock body 1 and the second lock body 2, and a through hole is opened in the center for the square shaft rod 4 to pass through, absorbing radial impact force through elastic deformation.

[0028] like Figure 2 As shown, an STM32F103C8T6 processor 8 is fixed at the top of the inner cavity of the first lock body 1. Its functions are: to receive input signals from the touch panel 10, to determine the correctness of the password through the internal program, to control the electromagnetic drive mechanism of the lock cylinder 3, and to monitor the battery power.

[0029] The cover plate 9 on one side of the processor 8 is connected to the first lock body 1 by a snap-fit. A battery is installed between the cover plate 9 and the processor 8 to power the processor 8, the lock cylinder 3 and the touch panel 10.

[0030] The second lock body 2 has a touch panel 10 of model TTP223 on its surface. Its function is to receive a 4-6 digit numeric password input by the user, transmit the electrical signal to the processor 8 through the wire, and integrate an LED indicator. The LED indicator shows green when the password is correct and red when it is incorrect.

[0031] The specific working principle is as follows, and the installation status is as follows: Figure 2 As shown, the first lock body 1 and the second lock body 2 are fixed to both sides of the door panel by bolts. The lock cylinder 3 passes through the thickness direction of the door panel. The two ends of the square shaft rod 4 are respectively inserted into the square holes of the first handle 7 and the second handle 11. The limit spring 5 is in a natural extension and retraction state. The positioning rubber plate 6 is tightly engaged between the two lock bodies to eliminate assembly gaps.

[0032] During the unlocking process, the user is Figure 1 When the password is entered on the touchpad 10 shown, the touchpad 10 of the TTP223 transmits the signal to the STM32F103C8T6 processor 8. After the processor 8 verifies the password, it controls the electromagnetic mechanism of the lock cylinder 3 to be energized, driving the bolt to retract. At this time, rotating the first handle 7 or the second handle 11 will drive the lock cylinder 3 to complete the mechanical unlocking through the square shaft rod 4.

[0033] When the door panel collides with the door frame Figure 3 The limiting spring 5 shown absorbs the impact force through axial extension and contraction, preventing the square shaft rod 4 from separating from the lock cylinder 3; the positioning rubber plate 6 buffers the radial force through elastic deformation, preventing the lock cylinder 3 from shaking in the lock body, and the double protection ensures the stability of the lock cylinder structure.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
