[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 and Figure 3 The utility model provides an embodiment: a door lock device for an electric side sliding door, including a car body 1 and a synchronous belt 7, a U-shaped plate 3 is fixedly connected to the left side of the front end of the car body 1, a rotating rod 4 is rotatably connected to the middle part of the front end of the U-shaped plate 3, and the rear end of the rotating rod 4 passes through the U-shaped plate 3, and the upper and lower ends of the inner front side of the U-shaped plate 3 are both rotatably connected to the screw rod 5, and the outer sides of the screw rod 5 and the rotating rod 4 are both fixedly connected to the synchronous wheel 6, and the multiple synchronous wheels 6 are connected by the synchronous belt 7. The outer side of the screw rod 5 is threadedly connected to a movable rod 8, and the rear side of the movable rod 8 passes through the car body 1, and a fixed frame 11 is provided on the inner side of the U-shaped plate 3. The rear end of the rotating rod 4 passes through the fixed frame 11 and is rotatably connected to the inner side of the middle part of the front end of the fixed frame 11, and a buffer mechanism 2 is provided inside the fixed frame 11. The left and right sides of the two movable rods 8 are fixedly connected to the sliders 9, and the left and right sides of the upper and lower ends of the inner front wall of the U-shaped plate 3 are fixedly connected to the sliding rods 10, and the sliding rods 9 are respectively slidably connected to the corresponding outer walls of the sliding rods 10;

[0032] Specifically, the synchronous wheel 6 on the outer side of the rotating rod 4 will rotate accordingly. At this time, the synchronous wheels 6 on the outer sides of the two screw rods 5 will also rotate synchronously. As the synchronous wheels 6 rotate, the screw rods 5 begin to work, and the movable rod 8 on the outer side will move backward accordingly and accurately insert into the installation hole reserved in advance in the vehicle body 1. This design cleverly utilizes the working principle of the screw rod 5 to achieve the precise positioning and installation of the movable rod 8. Through this mechanical linkage design, the installation process of the entire door lock device becomes extremely simple and efficient. The operator only needs to rotate the rotating rod 4 to install the door lock device, which greatly reduces the workload. At the same time, this design also ensures the accuracy and stability of the installation of the door lock device, meeting the needs of users.

[0033] Reference Figure 1 and Figure 4The buffer mechanism 2 includes a first hollow rod 201 and a connecting rod 211. The first hollow rod 201 is fixedly connected to the inner left side of the fixed frame 11. The first T-shaped rod 202 is slidably connected to the inner part of the first hollow rod 201. A first spring 203 is arranged on the outer side of the first hollow rod 201. One end of the first spring 203 is fixedly connected to the inner left side of the fixed frame 11. The other end of the first spring 203 is fixedly connected to the inner left side of the first T-shaped rod 202. The upper and lower sides of the inner part of the fixed frame 11 are fixedly connected to the second hollow rod 204. The second hollow rod 204 is slidably connected to the inner part of the second T-shaped rod 205. A second spring 206 is provided on the outside of the rod 204, one end of the second spring 206 is fixedly connected to one side of the interior of the fixed frame 11, the other ends of the two second springs 206 are respectively fixedly connected to one side of the corresponding second T-shaped rods 205, the adjacent ends of the two second T-shaped rods 205 are rotatably connected to the first rotating shaft 207, the interior of the fixed frame 11 is slidably connected to a spring plate 208, the upper and lower ends of the left side of the spring plate 208 are both fixedly connected to a fixed plate 209, the rear side of the fixed plate 209 is rotatably connected to a second rotating shaft 210, and the two second rotating shafts 210 are respectively connected to the corresponding first rotating shafts 207 through connecting rods 211;

[0034] Specifically, when the door 15 is closed, the door 15 generates an impact force on the spring plate 208, and the spring plate 208 will move to the left, and it will be linked with the second rotating shaft 210, thereby driving the second rotating shaft 210 to rotate. At the same time, the first rotating shaft 207 will also rotate through the connecting rod 211, and the second T-shaped rod 205 will accurately enter the second hollow rod 204. However, as the spring plate 208 continues to move to the left, it will squeeze the first T-shaped rod 202, and the first spring 203 will be squeezed, generating a reaction force. This reaction force is not a simple resistance, but accurately guides the first T-shaped rod 202 into the first hollow rod 201. The design of this step is ingenious in that it effectively reduces the impact force of the door 15 on the door lock structure. This shock absorption effect not only protects the door lock structure and makes it less susceptible to damage, but also improves the durability and stability of the entire door 15 system. When the door 15 needs to be opened, the first spring 203 and the second spring 206 will release the potential energy that was squeezed before. The release of this potential energy is fast and powerful, which drives the spring plate 208 to quickly return to the original position. This recovery mechanism not only improves the reaction speed of the door lock structure, but also enhances its service life and practicality.

[0036] Specifically, the vehicle door 15 can be opened and closed through the cooperation of the first electric push rod 13 and the second electric push rod 21, and the observation window 16 can facilitate passengers to observe the external situation at any time.

[0037] Reference Figure 2 , the first electric push rod 13 and the second electric push rod 21 are both electrically connected to the external controller;

[0038] Specifically, the operation of the first electric push rod 13 and the second electric push rod 21 can be controlled by an external controller.

[0039] Working principle: When installing the door lock device, first carry it to the front of the vehicle body 1 where it is to be installed, and then rotate the rotating rod 4. At this time, the synchronous wheel 6 on the outside thereof will rotate accordingly, and the synchronous wheels 6 on the outside of the two screw rods 5 will rotate accordingly through the synchronous belt 7. At this time, the movable rod 8 on the outside of the screw rod 5 will move backward and be inserted into the installation hole reserved in advance in the vehicle body 1. The installation of the door lock device is relatively simple, thereby reducing the workload of the staff and meeting the needs of the users. The vehicle door 15 can be driven to move to the left by the first electric push rod 13. When the locking buckle 18 completely enters the interior of the fixed frame 11, the buckle 22 can be driven forward by the second electric push rod 21 to be inserted into the locking buckle 18 to limit and fix the vehicle door 15. When the vehicle door 15 is closed, The spring plate 208 generates an impact force. At this time, the spring plate 208 moves to the left under the action of the impact force, thereby driving the second rotating shaft 210 to rotate, and the first rotating shaft 207 rotates accordingly through the connecting rod 211. At this time, the second T-shaped rod 205 enters the second hollow rod 204, and then the spring plate 208 continues to move to the left to squeeze the first T-shaped rod 202. At this time, the first spring 203 is squeezed and drives the first T-shaped rod 202 to enter the first hollow rod 201, which can reduce the impact force of the car door 15 on the door lock structure, and the door lock structure is not easily damaged. When the car door 15 is opened, the first spring 203 and the second spring 206 release the squeezed potential energy and drive the spring plate 208 to return to its original state, thereby improving the practicality of the device.
