[0037] In order to make the purpose, technical solutions and advantages of this application clearer, the following will be combined with the attached Figure 1-4 The present application is further described in detail. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0038] It should be understood that although the terms first, second, third, etc. may be used to describe in the embodiments of the present application, these descriptions should not be limited to these terms. These terms are only used to distinguish the descriptions. For example, without departing from the scope of the embodiments of the present application, the first may also be referred to as the second, and similarly, the second may also be referred to as the first.

[0039] The present application provides an anti-theft structure for a vehicle door lock, comprising: a handle base 2 to which a lock core assembly 1 is fixed; the lock core assembly 1 is connected to a door lock assembly 4 via a lock core connecting rod 3; it is characterized in that an anti-theft structure 5 is arranged on the handle base 2 above the lock core assembly 1; the anti-theft structure 5 comprises: a shielding plate 51 and an alarm device arranged on the shielding plate 51; the right side of the shielding plate 51 is clamped on the handle base 2.

[0040] It can be understood that the present application connects the shielding plate 51 and the handle base 2 through a snap-on structure, which is structurally convenient for installation and disassembly; wherein, through the alarm device on the shielding plate 51, when the thief's tool approaches the shielding plate 51 or touches the shielding plate 51, the alarm device can be triggered, thereby playing the role of an anti-theft alarm to warn people and scare away thieves. Through the design of the shielding plate 51, it is possible to prevent theft tools from extending between the door glass and the outer water cut, and abnormally opening the door, thereby enhancing the anti-theft effect of the door lock.

[0041] Specifically, the shielding plate 51 is made of hard plastic material. The advantages of this design are that it is easy to process and reduces costs.

[0042] Optionally, the upper and lower edges of the inner middle part of the handle base 2 are both provided with a first reinforcing rib 21, wherein two second reinforcing ribs 22 are also provided on the handle base 2 between the upper and lower edges; an oblique reinforcing rib 24 is provided between the second reinforcing rib 22 and the first reinforcing rib 21; the oblique reinforcing rib 24 divides the space enclosed by the second reinforcing rib 22 and the first reinforcing rib 21 into a continuous trapezoidal area; a longitudinal reinforcing rib 23 is provided between the two second reinforcing ribs 22; the advantage of this design is that the connection strength of the handle base 2 is improved as a whole by the second reinforcing rib 22, the first reinforcing rib 21, the oblique reinforcing rib 24 and the longitudinal reinforcing rib 23, while the vibration resistance and fatigue resistance of the handle base 2 are increased.

[0043] Optionally, the shielding plate 51 is a slide-like structure as a whole, which includes a bending portion 510 in the middle, a shielding portion 511 integrally connected to the left side of the bending portion 510, a transition portion 512 integrally connected to the right side of the bending portion 510, and a fixing portion 513 extending downward on the side of the transition portion 512 away from the bending portion 510; an arc-shaped protective plate 518 is extended downward on the left side of the shielding portion 511; wherein the protective plate 518, the shielding portion 511, the bending portion 510 and the transition portion 512 jointly cover the top of the lock core assembly 1.

[0044] It can be understood that the design advantages of the shielding plate 51 as a whole being a slide-like structure are as follows: the overall strength of the shielding plate 51 designed with a slide-like structure is improved, and secondly, the bending portion 510 plays a avoiding role, which facilitates the installation and fixation of the shielding plate 51.

[0045] Optionally, two fixing pins 514 are arranged side by side on the right side of the fixing portion 513 , and correspondingly, a fixing slot for engaging with the fixing pins 514 is arranged on the handle base 2 ; a reinforcing rib is arranged on one side of each fixing pin 514 .

[0046] Optionally, a Z-shaped positioning pin 515 is provided on the fixing portion 513 between two adjacent fixing pins 514, and correspondingly, a positioning groove for cooperating with the positioning pin 515 is provided on the handle base 2; through the design of the positioning pin 515, the installation and positioning between the fixing portion 513 and the handle base 2 are facilitated, and the connection strength between the fixing portion 513 and the handle base 2 is further strengthened.

[0047] Optionally, in order to further enhance the overall strength of the shielding plate 51 , at least two diamond-shaped reinforcing ribs 516 are provided at the lower end of the connection between the bending portion 510 and the shielding portion 511 and at the upper end of the connection between the bending portion 510 and the transition portion 512 .

[0048] Optionally, a mounting hole 517 is provided on the shielding portion 511; an alarm device is provided at the mounting hole 517; wherein the shielding portion 511 corresponds to the top of the lock core swing arm 6 of the lock core assembly 1; the advantage of this design is that it is easy for the theft tool to trigger the alarm device, thereby sounding an alarm in the first time to scare away the thief.

[0049] The alarm device includes an alarm sensor and a buzzer; wherein the alarm sensor is electrically connected to a connector 52 on the handle base 2 via a wiring harness, and the connector 52 is electrically connected to the buzzer via a wiring harness; the alarm sensor is an infrared sensor or a pressure sensor.

[0050] When the stealing tool approaches or touches the shielding plate 51, the alarm sensor is triggered. At this time, the beeper emits an alarm sound according to the alarm signal sent by the alarm sensor to scare away the thief.

[0051] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.
