[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A door hinge assembly with a built-in limiter includes a connecting hole at the left end of a body component. A door component is located below the left end of the body component. A first mounting seat is vertically provided at the right end of the door component. A second mounting seat is horizontally provided on one side of the first mounting seat. A positioning roller is rotatably mounted in the first mounting seat. A hinge pin is coaxially mounted on the positioning roller. The connecting hole of the body component is bolted to the top of the hinge pin. A push rod is slidably mounted in the second mounting seat. One side of the push rod cooperates with the positioning roller through a needle roller. A connecting rod is fixedly mounted on the other side of the push rod. A spring is fitted on the connecting rod. Threaded pins are provided at both ends of the spring and fixedly connected to the push rod. The threaded pins are screwed onto one end of the second mounting seat.

[0006] A further preferred embodiment of this utility model is that the body part is arc-shaped, and a weight-reducing groove is provided on the rear side of the body part.

[0007] A further preferred embodiment of this utility model is as follows: a fixing plate is fixedly installed on both the body parts and the door parts, and each fixing plate has four mounting holes.

[0008] A further preferred embodiment of this utility model is: a limiting block is fixedly installed on the outer wall of the first mounting seat of the door component.

[0009] The present invention has the following advantages:

[0010] 1. This utility model solves the problem caused by separating the door hinge and the limiter by integrating the limiter into the first mounting base, which facilitates vehicle assembly and improves assembly speed.

[0011] 2. This utility model can better ensure the lightweighting of vehicles by setting weight reduction grooves, which meets production requirements. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1:

[0019] according to Figure 1-4 As shown, a door hinge assembly with a built-in limiter includes a connecting hole at the left end of a body component 1. A door component 2 is located below the left end of the body component 1. A first mounting seat 8 is vertically located at the right end of the door component 2. A second mounting seat 9 is horizontally located on one side of the first mounting seat 8. A positioning roller 12 is rotatably mounted inside the first mounting seat 8. A hinge pin 11 is coaxially mounted on the positioning roller 12. The connecting hole of the body component 1 is connected to the top of the hinge pin 11 by a bolt 6. A push rod 13 is slidably mounted inside the second mounting seat 9. One side of the push rod 13 cooperates with the positioning roller 12 through a needle roller. Here, the needle roller is rotatably mounted at the junction of the first mounting seat 8 and the second mounting seat 9. A connecting rod is fixedly mounted on the other side of the push rod 13. A spring is fitted on the connecting rod. Threaded pins 10 are respectively provided at both ends of the spring and fixedly connected to the push rod 13. The threaded pins 10 are screwed onto one end of the second mounting seat 9. This arrangement allows for spring adjustment.

[0020] The body part 1 is arc-shaped, and a weight reduction groove 3 is provided on the rear side of the body part 1. This design can ensure the vehicle's lightweight design.

[0021] Both body part 1 and door part 2 are fixedly installed with mounting plates 5. Each mounting plate 5 has four mounting holes 7, which facilitates the installation of the door and the body, facilitates the assembly of the whole vehicle, and improves the assembly cycle.

[0022] A limit block 4 is fixedly installed on the outer wall of the first mounting seat 8 of the door component 2, which can serve as a limit.
