[0002] Door locks are key components to ensure home safety, and the base plate, which is in close contact with the door, is crucial in selection. Currently on the market, some door locks use rigid materials as base plates, which can provide stable structural support, ensure that the door locks are not easily deformed during installation and daily use, and maintain good mechanical properties. However, rigid materials are expensive, and have poor buffering effects when facing external impacts, which can easily cause damage to door lock components and reduce service life. In addition, abnormal noises are prone to occur when they directly contact the door panel. Although the use of elastic materials as base plates can effectively buffer external forces, reduce component damage, and reduce abnormal noises, the stability of elastic materials is poor, making it difficult to ensure long-term stable operation of door locks, affecting normal unlocking and locking functions.

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0024] Reference Figure 1-7 As shown, the door lock with a short sealing plate structure includes a base plate 1 and a housing 2 mounted on the base plate 1;

[0025] The bottom plate 1 includes a buffer pad 11 and a rigid plate 12;

[0026] The rigid plate 12 is fixedly connected to the outer shell 2, and the buffer pad 11 is located between the rigid plate 12 and the outer shell 2. The rigid plate 12 is smaller than the outer shell 2 and the buffer pad 11. A groove 111 for the rigid plate 12 to enter is provided at a position corresponding to the rigid plate 12 on the buffer pad 11, and the depth of the groove 111 is greater than the thickness of the rigid plate 12.

[0027] The rigid plate 12 is embedded in the groove 111 of the buffer pad 11. The buffer pad 11 first contacts the door to reduce the force of the rigid plate 12 contacting the door. When the door lock is opened or closed, the lock core rotates to apply the door lock force. The buffer pad 11 buffers the force by deformation. When the buffer pad 11 is deformed, the part of the buffer pad 11 corresponding to the rigid plate 12 maintains its original shape, ensuring that the lock core and the housing 2 will not make abnormal noises. At the same time, the rigid plate 12 provides support force to ensure that the lock core and the housing 2 remain in place.

[0028] In the prior art, a rigid plate 12 is used to contact the door. During daily use, the rigid plate 12 can provide good supporting force to resist the torsional force caused by the rotation of the lock body. However, when faced with external force impact, the rigid plate 12 will conflict and collide with the door lock to produce abnormal noise, and it is easy to cause the door lock to be squeezed and deformed, resulting in the door being unable to open and close normally. A buffer pad 11 is used to contact the door, which can absorb the torsional force and abnormal noise caused by the rotation of the lock body, but at the same time it will cause the buffer pad 11 and the door lock to be displaced, such as the displacement of the lock core and the lock hole, resulting in the inability to rotate normally, thereby making the door unable to open or close normally. The utility model nests the rigid plate 12 in the buffer pad 11, and the buffer pad 11 contacts the door to absorb the force, and the rigid plate 12 provides supporting force to strengthen the direct connection between the door lock and the door. At the same time, the manufacturing cost of the buffer pad 11 is lower than that of the rigid plate 12. By reducing the size of the rigid plate 12, the manufacturing cost of the door lock can be effectively reduced.

[0029] The rigid plate 12 at least covers the portion of the housing 2 for connecting the lock cylinder.

[0030] When the door is opened or closed, the lock core rotates, thereby driving the shell 2 to rotate. The shell 2 is connected to the buffer pad 11. The rotation of the shell 2 drives the buffer pad 11 to rotate. The buffer pad 11 deforms to absorb the force of the rotation of the shell 2. The rigid plate 12 embedded in the buffer pad 11 hinders the deformation of the corresponding part of the buffer pad 11, thereby ensuring that the position of the lock core remains intact. At the same time, other parts of the buffer pad 11 absorb the rotation force to reduce abnormal noise between the door lock and the door.

[0031] The rigid plate 12 has a positioning post 121 , and the housing 2 is provided with a positioning groove 21 at a position corresponding to the positioning post 121 . The positioning post 121 passes through the buffer pad 11 and is inserted into the positioning groove 21 .

[0032] The positioning column 121 passes through the through hole of the buffer pad 11 and is inserted into the positioning groove 21. The rigid plate 12 can be quickly installed on the buffer pad 11 through the positioning column 121, and the buffer pad 11 can be installed in the shell 2 at the same time. The setting of the positioning column 121 can also play a fixing role when the shell 2 and the buffer pad 11 are displaced, reducing the displacement. When the shell 2 and the buffer pad 11 are greatly displaced due to external force, the door lock is driven to move as a whole to ensure that the lock core will not be deformed due to the displacement of a single component of the shell 2 or the buffer pad 11.

[0033] A display 22 is arranged in the shell 2, and a receiving groove 23 for receiving the display 22 is arranged at a position corresponding to the display 22 on the shell 2, the bottom of the receiving groove 23 corresponds to the buffer pad 11, and the buffer pad 11 is attached to the bottom of the outside of the receiving groove 23, and the bottom of the receiving groove 23 cooperates with the buffer pad 11 to fit with the door.

[0034] The receiving groove 23 is used to protect the display 22 from being damaged by external forces. At the same time, the receiving groove 23 fits tightly with the door through the buffer pad 11, so that there is no vibration and friction between the receiving groove 23 and the door. The buffer pad 11 plays a buffering role for the receiving groove 23, thereby reducing the collision force on the display 22.

[0035] The receiving groove 23 is provided with a through groove 24 , and the housing 2 is provided with a wiring groove 25 . The through groove 24 is used for the wire to pass through and connect to the wiring groove 25 .

[0036] The display 22 is connected to the wiring slot 25 through a wire, and the wire passes through the through slot 24. The through slot 24 provides a safe space for the wire to avoid the wire contacting with a conductive material to cause a short circuit, thereby improving the safety of the door lock.

[0037] The buffer pad 11 is provided with a sinking groove 112 corresponding to the display screen portion. The sinking groove 112 abuts against the bottom of the outer portion of the receiving groove 23 and leaves a channel for the wire to pass through.

[0038] The sunken groove 112 is used to provide flatness for the portion of the display screen corresponding to the buffer pad 11, so that the display 22 can fit better on the door. At the same time, the sunken groove 112 interferes with the accommodating groove 23 to separate the rigid plate 12 and the wire, avoiding the phenomenon of short circuit caused by the wire contacting the rigid plate 12, thereby improving the safety of the door lock.

[0039] The rigid plate 12 is provided with an assembly notch 122 for matching with the sunken groove 112 , and the assembly notch 122 is used to separate the rigid plate 12 from the wiring slot 25 .

[0040] The assembly notch 122 cooperates with the sunken groove 112 to ensure that the rigid plate 12 and the buffer pad 11 have a better flat surface, so that the rigid plate 12 and the buffer pad 11 fit closely to the door. At the same time, the wiring groove 25 will conflict with the buffer pad 11, causing the buffer pad 11 to wear and break. The assembly notch 122 is set so that after the buffer pad 11 corresponding to the wiring groove 25 is partially broken, the wiring groove 25 will not contact the rigid plate 12, thereby improving the safety of the door lock.

[0041] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
